New analysis from Frost & Sullivan (http://www.patientmonitoring.frost.com), Data Management Systems for Patient Monitoring Markets in Europe, finds that the markets earned revenues of $126.8 million in 2009 and estimates this to reach $161.4 million in 2013. The markets covered in this research service are electrocardiography (ECG), sleep and respiratory, neurological and anaesthesia monitoring.

“European healthcare systems are witnessing a surge in activities involving IT solutions, mainly due to the affordability and need to effectively manage large volumes of data,” notes Frost & Sullivan Research Analyst, CK  Somsainathan. “Most countries are highly receptive to such technology and are fully aware of its benefits, thereby rapidly driving the growth of these systems in Europe.”

The European patient monitoring markets are experiencing significant growth due to the rising number of patients availing healthcare services. Thus, DMSs used in patient monitoring are sufficient for real-time management of data, as they help in instantly charting a patient’s data. Similarly, the stimulus package provided to the healthcare sector in Europe is also fuelling the introduction of cost-effective IT solutions to ease workloads.

However, outdated technology in a few countries is limiting the usage of sophisticated DMSs.

“The inability to electronically document data, due to outdated systems and low levels of awareness are the major hurdles to the DMS market,” explains Somsainathan. “Outdated systems that are not compatible with the latest technological version of DMS are still prevalent across Europe, further hindering growth.”

Low end-user confidence in the successful implementation of such systems and pressure on data management solutions providers to provide swift delivery of systems are some of the other challenges faced by the market participants.

DMS participants should improvise on cost-effective solutions and enhanced open platform software that will help them penetrate the markets more effectively. Early adopters of technology such as Germany, the United Kingdom and France are prototypes for other conservative markets that are gradually adopting such technology. Superior software that will be compatible with old machines, coupled with awareness programmes to present the advantages of using these systems, will help the market participants in promoting their sales.

“Simplified solutions, open platform software and the provision of training for staff on the usage of systems will facilitate the market participants to penetrate the market with ease,” concludes Somsainathan. “However, smaller companies vying for market space should switch to product differentiation techniques for exciting opportunities.”

Data Management Systems for Patient Monitoring Markets in Europe is part of the Patient Monitoring Growth Partnership Services programme, which also includes research in the following markets: Emerging Technologies in Cardiac Monitoring, European Markets for Multiparameter Mid-range Patient Monitors, Patient Monitoring – Business in Saturated Markets, and European Market for Anaesthesia Equipment and Associated Airway Management Devices.

those people with non-permanent AF patients whose AF is not controlled by first-line therapy (usually including beta blockers) and who have at least one of the following risk factors:

• Hypertension requiring 2 drugs of at least 2 different classes
• Diabetes mellitus
• Previous transient attack (TIA), stroke or systemic embolism
• Left atrial diameter ≥50 mm
• Left ventricular ejection fraction <40% (dronedarone not recommended for  those with LVEF <35%) or age 70 years or more and who do not have unstable New York Heart Association (NYHA) class III or IV heart failure.

People who do not meet these criteria, who are currently receiving dronedarone should have the option to continue treatment until they or their clinicians consider it appropriate to stop.

The recommendations from NICE have been broadly welcomed. They follow a sustained campaign by cardiologists and other healthcare professionals (HCP) along with the Arrhythmia Alliance to have dronedarone available for prescription with NHS funding.

A new website, www.multaq.co.uk is available for HCPs, which has specific section for patients, and carries general information about atrial fibrillation and Multaq in particular.

ZOLL also won joint supplier status Level 2 and Level 3 for its AED Pro^® for the next three years.  If fully exercised, the potential revenue for the contract could exceed £1.5 million for all three levels.

The tender process included leading professionals from both the medical community and ambulance services. It scrutinized all aspects vital to the delivery of the BHF Community Resuscitation programme including the clinical aspects of the devices, account management, compliance with resuscitation guidelines and compatibility with the ambulance service.

“One in three people who experience sudden cardiac arrest die before reaching the hospital. Experts believe these figures could be reduced drastically if there were more defibrillators in public places,” stated Claire O’Neill, Community Resuscitation Lead, British Heart Foundation. “We are delighted to be continuing our productive working relationship with ZOLL to place more AEDs in the community.”

Current advice is often confused and this can result in inappropriate restrictions being placed on the travel plans of thousands of patients. Healthcare professionals and patients have not had, until now, clear guidance based on the latest evidence to help give them the right advice. This is going to change in August when the British Cardiovascular Society (BCS)  publishes a report on passengers’ cardiovascular ‘Fitness to Fly’ in the journal, Heart.

On Tuesday 20 July, the report will be launched online at BMJ’s Heart website (http://heart.bmj.com) and on the BCS website (www.bcs.com).  The ‘Fitness to Fly’ report shows that there are very few heart conditions that mean that patients can’t fly safely. However, passengers are advised to inform their airline of any pre-existing heart conditions that they may have and take other precautions in their preparation to fly.

Whilst airlines do have the right to deny passage on the basis of a pre-existing heart condition, this report gives clear evidence that such denial is unnecessary in the vast majority of cases. This will be of great use to the travelling public and to all healthcare professionals and will mean that thousands of heart patients will be able to travel by air, reassured that expert guidelines have shown that it is safe to do so.

The comprehensive report includes a summary table of various specific heart conditions with advice on any necessary guidance or restrictions that should be considered for the passenger, as well as a thorough review and consideration of current evidence within this area.

The report is the result of a working group formed by the British Cardiovascular Society (BCS) at the end of 2008, at the prompting of the House of Lords’ Science and Technology Committee. The working group was led by Dr David Smith, a Consultant Cardiologist based at the Royal Devon and Exeter Foundation Trust, and included representation from Airlines, Aviation authorities and experts from the field of Cardiology.

Keith Fox, President of the BCS said, “The new guidelines on fitness to fly for patients with heart conditions are good news for patients and good news for doctors. The British Cardiovascular Society publication (led by Dr David Smith) advises that there are very few heart conditions that mean a person should not fly.  For the first time, doctors have also been provided with clear and straightforward guidelines.”

“This is a trial of major significance since no anti-arrhythmic drug has ever been shown to reduce major morbidity and mortality in permanent AF patients in a large-scale clinical trial,” said Dr Stuart Connolly, Division of Cardiology, McMaster University, Hamilton, Canada, one of the trial’s principal investigators. “We designed the PALLAS trial to further assess the role of Multaq^® to reduce cardiovascular outcomes in patients with AF.”

The primary objective of the PALLAS (Permanent Atrial fibriLLAtion outcome Study using Dronedarone on top of standard therapy) trial is to demonstrate a reduction in either or both of two composite outcomes which are 1. major cardiovascular events (stroke, systemic arterial embolism, myocardial infarction or cardiovascular death) or 2. cardiovascular hospitalization or death from any cause among patients with permanent atrial fibrillation and additional risk factors. The secondary objectives are to evaluate the efficacy of Multaq^® in preventing cardiovascular death and whether the drug is well-tolerated in this patient population.

About PALLAS

PALLAS* is a multinational, randomized, double-blind, parallel-group, placebo-controlled, multicenter Phase IIIb trial comparing the efficacy of Multaq^® 400mg twice-daily with placebo in permanent AF patients. All patients will receive standard treatment to control heart rate and prevent blood clots (antithrombotic therapy); patients will be randomized to receive additional treatment with either Multaq^® 400mg BID or placebo.

Required risk factors include age above 65 years with at least one of the following major risk factors: systemic arterial embolism, myocardial infarction, documented coronary artery disease, prior stroke, symptomatic heart failure, or the combination of age above 75 years, hypertension and diabetes mellitus. Exclusion criteria include patients with New York Heart Association (NYHA) Class IV heart failure or unstable NYHA Class III heart failure.

The trial has two composite co-primary endpoints: 1. Major cardiovascular events (stroke, systemic arterial embolism, myocardial infarction or cardiovascular death). 2. Cardiovascular hospitalization or death from any cause.

There will be 10,800 patients enrolled in 43 countries at 700 sites. The trial is event-driven with a fixed Common Study End Date, meaning that the study duration will depend upon the occurrence of a statistically required number of outcome events.

Allopurinol is a drug used primarily to treat individuals with excess uric acid. Hyperuricemia can lead to gout and, in extreme cases, kidney failure. Elevated uric acid may also increase risk of developing hypertension and heart disease. Patients with CKD–who most often die from heart disease.

To investigate, Marian Goicoechea, PhD, Jose Luño, MD, Hospital General Universitario Gregorio Marañón, in Madrid, Spain) and their colleagues conducted a prospective, randomized trial of 113 CKD patients who received either allopurinol (100 mg/day) or who continued taking their usual therapy. The researchers assessed kidney disease progression, cardiovascular events and hospitalizations among patients in the study over two years.

The blood levels of uric acid and C-reactive protein significantly decreased in patients treated with allopurinol. In the control group, kidney function declined after two years, but in the allopurinol-treated group, kidney function improved. Allopurinol treatment slowed down kidney disease progression regardless of patients’ age, gender, and diabetes status; their blood levels of uric acid and C-reactive protein; the amount of  protein patients lost in the urine; and the other types of medications patients used. In addition, compared with usual therapy, allopurinol treatment reduced the risk of cardiovascular events by 71% and the risk of hospitalizations by 62%.

While allopurinol has significant potential benefits for CKD patients, “these results have to be confirmed in larger prospective trials and are the basis for a hypothesis that still needs to be tested,” the authors wrote.

Study co-authors include Soledad García de Vinuesa, Ursula Verdalles, Caridad Ruiz-Caro, Jara Ampuero, Abraham Rincón, and David Arroyo of Hospital General Universitario Gregorio Marañón.

Allopurinol in angina pectoris

Another study (2) in the Lancet shows that the drug prolongs exercise capacity in chronic stable angina, and could thus be a cheap alternative to conventional treatments. The study, from Professor Allan D Struthers, University of Dundee, UK, and colleagues.

Experimental evidence on allopurinol suggests that it inhibits the enzyme xanthine oxidase, which in turn reduces the energy used by the heart in each beat or ‘stroke’. If such an effect also occurs in man, this class of inhibitors could become a new treatment for ischaemia in patients with angina pectoris, since it would allow more oxygen and energy to reach heart tissue suffering inadequate blood supply in angina patients. In this study, the authors assessed whether high-dose allopurinol prolongs exercise capability in patients with chronic stable angina.

65 patients (aged 18–85 years) with clinically diagnosed coronary artery disease, a positive exercise tolerance test*, and stable chronic angina pectoris (for at least 2 months) were recruited into a double-blind, randomised, placebo-controlled, crossover study in a hospital and two infirmaries in the UK. Patients were assigned to allopurinol (600 mg per day) or placebo for 6 weeks and then crossed over to take placebo or allopurinol, so that each patient received both treatments in a randomised fashion. The primary endpoint was the time to ST depression, and the secondary endpoints were total exercise time and time to chest pain.

In the first treatment period, 31 patients were allocated to allopurinol and 28 were analysed, and 34 were allocated to placebo and 32 were analysed. In the second period, all 60 patients were analysed. Allopurinol increased the median time to ST depression to 298 s from a baseline of 232 s, and placebo increased it to 249 s. The absolute difference between allopurinol and placebo was 43 s. Allopurinol increased median total exercise time** to 393 s from a baseline of 301 s, and placebo increased it to 307 s, giving an absolute difference between groups of 58 s. Allopurinol also increased the time to chest pain from a baseline of 234 s to 304 s, and placebo increased it to 272 s, an absolute difference between groups of 38 s. No adverse effects of treatment were reported.

The authors say: “Allopurinol is inexpensive compared with some other antianginal drugs such as ranolazine and ivabradine, and has a favourable long-term (>40 years) safety record for the treatment of gout. Compared with older antianginal drugs (nitrates, β blockers), allopurinol is better tolerated because it does not reduce blood pressure or heart rate, and does not cause many side-effects, such as headaches and tiredness, that occur frequently with nitrates and β blockers.”

They conclude: “High-dose allopurinol significantly prolonged the time to ST depression, the total exercise time, and the time to angina in patients with chronic stable angina during a standard exercise test, suggesting that endogenous xanthine oxidase activity contributes somehow to exercise-induced myocardial ischaemia. These results also show that high-dose allopurinol prolongs exercise in stable angina pectoris…on the basis of our results, allopurinol is a useful anti-ischaemic treatment option in patients with angina that has the advantage of being inexpensive, well tolerated and safe in the long term. The precise place of allopurinol in the management of angina pectoris now needs to be explored further, but this drug might be especially appealing for use in developing countries where coronary artery disease is rapidly increasing in frequency and where access to expensive drugs or invasive treatments (angioplasty and bypass surgery) is often restricted.”

In an accompanying Comment, Dr Henry J Dargie, Scottish Advanced Heart Failure Service, Golden Jubilee National Hospital, Clydebank, West Dunbartonshire, UK and Western Infirmary, Glasgow, UK and Dr Renjith Antony Scottish Advanced Heart Failure Service, Golden Jubilee National Hospital, Clydebank, West Dunbartonshire, say: “Although further work is needed to confirm allopurinol’s putative anti-ischaemic effects and to better understand its mechanism of action, allopurinol joins a growing list of compounds that tests the conventional wisdom on what constitutes antianginal therapy. Although prevention of coronary artery disease remains important, protecting the heart muscle from ischaemia is a logical and pragmatic approach to a disabling condition for which several mechanisms might be responsible.”

Dr Tuula Paajanen, a researcher at the Department of Forensic Medicine, University of Tampere, Tampere, Finland, said that over the years there had been a number of studies that had provided conflicting evidence on whether shortness was associated with heart disease.

“The first report on the inverse association between coronary heart disease (CHD) and height was published in 1951 and, since then, the association between short stature and cardiovascular diseases has been investigated in more than 1,900 papers. However, until now, no systematic review and meta-analysis has been done on this topic.

We hope that with this meta-analysis, the association is recognised to be true and in future more effort is targeted to finding out the possible pathophysiological, environmental and genetic mechanisms behind the association, with eyes and minds open to different hypotheses,” she said.

Due to the many different ways that previous studies have investigated the association between height and heart disease, Dr Paajanen and her colleagues decided to compare the shortest group to the tallest group instead of using a fixed height limit.

From the total of 1,900 papers, the researchers selected 52 that fulfilled all their criteria for inclusion in their study. These included a total of 3,012,747 patients. On average short people were below 160.5 cms (5.2 ins) high and tall people were over 173.9 cms (5.7 ins). When men and women were considered separately, on average short men were below 165.4 cms and short women below 153 cms, while tall men were over 177.5 cms and tall women over 166.4 cms.

Dr Paajanen and her colleagues found that compared to those in the tallest group, the people in the shortest group were nearly 1.5 times more likely to die from cardiovascular disease (CVD) or coronary heart disease (CHD), or to live with the symptoms of CVD or CHD, or to suffer a heart attack, compared with the tallest people.

Looking at men and women separately, short men were 37% more likely to die from any cause compared with tall men, and short women were 55% more likely to die from any cause compared with their taller counterparts.

“Due to the heterogeneity of studies, we cannot reliably answer the question on the critical absolute height,” write the authors in their study. “The height cut-off points did not only differ between the articles but also between men and women and between ethnic groups. This is why we used the shortest-vs.-tallest group setting.”

The findings have clinical implications. Dr Paajanen said: “The results of this systematic review and meta-analysis suggest that height may be considered as a possible independent factor to be used in calculating people’s risk of heart disease. Height is used to calculate body mass index, which is a widely used to quantify risk of coronary heart disease.”

It is not known why short stature should be associated with increased risk of heart disease. Dr Paajanen said: “The reasons remain open to hypotheses. We hypothesize that shorter people have smaller coronary arteries and smaller coronary arteries may be occluded earlier in life due to factors that increase risk, such as a poorer socioeconomic background with poor nutrition and infections that result in poor foetal or early life growth.

Smaller coronary arteries also might be more affected by changes and disturbances in blood flow. However, recent findings on the genetic background of body height suggest that inherited factors, rather than speculative early-life poor nutrition or birth weight, may explain the association between small stature and an increased risk of heart disease in later life. We are carrying out further research to investigate these hypotheses.”

Dr Paajanen said that it was important that short people should not be worried by her findings. “Height is only one factor that may contribute to heart disease risk, and whereas people have no control over their height, they can control their weight, lifestyle habits such as smoking, drinking and exercise and all of these together affect their heart disease risk. In addition, because the average height of populations is constantly increasing, this may have beneficial effect of deaths and illness from cardiovascular disease.”

In an editorial on the research published at the same time [2], Jaakko Tuomilehto, Professor of Public Health at the University of Helsinki, Helsinki, Finland, welcomed the study, writing: “The systematic review and meta-analysis on this topic . . . is well justified 60 years after the first observation and the hundreds of other papers which have been published since then on this topic.

The results are unequivocal: short stature is associated with increased risk of coronary heart disease. This meta-analysis provides solid proof for this, but, as the authors conclude ‘The possible pathophysiological, environmental, and genetic background of this peculiar association is not known’.”

He suspects that environmental events affecting growth before and after birth may be involved. “Socio-economic adversity in childhood is . . . associated with delayed early growth and shorter adult stature. The so-called catch-up growth during the first years of life among children who are born small has negative health effects in adulthood; much of the early growth is due to greater fat accumulation. Thus, it is most likely that short stature is the link to coronary heart disease, and that tallness is not a primary factor in preventing the disease, although it indicates healthy growth. Short stature seems to be a marker for risk.”

While more work is needed to understand the exact nature of the mechanisms at work, he writes that information on height can be used now for the prevention of heart disease and other chronic diseases linked to shortness. “Full term babies who are born small are likely to be short as adults. They should receive preventive attention early on.

The primordial prevention of chronic diseases should start during foetal life, and health promotion should be targeted to all pregnant women with the aim of health development of the foetus.

Low birth weight and some other birth characteristics can reveal potential problems during this period of life. After that, in babies with low birth weight, it is important to avoid excessive catch-up growth, i.e. early-life fatness.”

In adult life it becomes more difficult to discover best practices, but Prof Tuomilehto, thinks it is likely short adults would benefit from more aggressive risk factor reduction.

He concludes: “Most of us know approximately our own height ranking, and, if we are at the low end, we should take coronary risk factor control more seriously. On the other hand, tall people are not protected against coronary heart disease, and they also need to pay attention to the same risk factors as shorter people.”

This is the first time that a telehealth system combining remote patient monitoring with motivational educational support tools has been researched, and the results demonstrate significant additional value and effectiveness for managing the health of chronically ill heart failure patients. Previous studies have analyzed the advantages of telehealth in terms of patient care, decrease in hospital admissions and cost savings, such as TEN-HMS (2005)[i]. The CARME study now demonstrates the additional benefit for patients of including remote educational and motivational tools to improve their quality of life.

The study monitored 92 patients with severe heart failure at home, managed by the Hospital Germans Trias i Pujol Heart Failure Clinic. The interactive telehealth system Philips Motiva was used to connect patients to their healthcare providers via their home television and a broadband internet connection. Patients can take vital measurements in their homes and communicate the information to their physician via the system, and they can also receive educational and motivational information from their physician to help manage their health.

Improvement in clinical results and quality of life

The final data from the CARME study show a significant clinical benefit in using the Motiva system to monitor heart failure patients in the home, by comparing clinical outcomes 12 months prior to enrollment with the results obtained during the observation period. Results of the study showed a decrease of 68 percent in heart failure related hospitalizations and a reduction of days spent in hospital by 73 percent.

CARME also reveals that patients showed a continuous and significant improvement in their perception of quality of life over the 12 month observation period, an improvement that ranged from 62 percent to 72 percent (depending on the methodology used to measure it (questionnaires “Minnessota Living with Heart Failure” and EuroQoL respectively).

A post-analysis of the results (not presented at the Congress) shows that, at the beginning of the study, more than half of the patients (56 percent) said that their quality of life was “medium” or “low”; this number decreased to 22 percent at the end. Also, the number of patients that considered their quality of life to be “medium-high” rose from 44 percent at the beginning of the study to 78 percent after one year, and more than one-quarter of respondents (28 percent) considered quality of life to be “almost excellent.”

In addition, satisfaction with the telemonitoring system was high, especially in those patients who had vital measurements added to their educational and motivational tools. Up to 81 percent of these patients wanted to keep the solution in addition to their regular care.

Study design

The patients in the CARME study were randomly assigned to two groups: in one group, the patients received care plan-driven educational videos, motivational messages and questionnaires. The second group received the same information but was also requested to monitor their blood pressure, pulse rate and weight.

“The concept of providing educational support to heart failure patients via their television has significantly contributed to empowering them. Equally important, the CARME study has shown that disseminating patient and disease specific information via the TV, through Philips Motiva, helps family members to gain a better understanding of how to effectively support their loved ones in coping with their disease. This appears to have a very strong impact on outcomes,” said Dr. Josep Lupon, head of the Heart Failure Unit and main researcher of the study.

The future outlook of telehealth solutions

As part of the EU-funded MyHeart research project, Philips and partners are developing an advanced heart-failure management system that could provide more comprehensive information about a patient’s condition and may enable earlier intervention. This experimental heart failure management system consists, among others, of a wearable textile vest with an embedded innovative sensor designed to assess the accumulation of fluid in the lungs, the latter being a potentially life-threatening condition heart-failure patients have a serious risk suffering from. In addition, the EU-funded HeartCycle project headed by Philips explores comprehensive patient-centric solutions based on innovative sensors for chronic disease management at home.

“MRI scanning is unequivocally superior to X ray based imaging methods and is fast becoming an essential diagnostic tool for clinicians. Existing pacemaker technology meant that MRI scans were not safe for over a quarter of a million patients because of the strong magnetic fields it uses” said Dr Jonathan Lyne, cardiologist at Royal Brompton Hospital, London.  “The launch of an MRI safe pacemaker will mean that these patients will not need more invasive or complicated diagnostic procedures and will lead to speedier and more accurate diagnoses.

“Furthermore patients with chronic conditions requiring repeated imaging investigations will be able to benefit from MRI scanning as opposed to X ray based alternatives, helping to reduce the patient’s exposure to radiation.”

Approximately two million Europeans have implanted pacemakers. Until the availability of Medtronic SureScan pacing systems, patients with pacemakers have been strongly discouraged from receiving MRI scans. There is the potential for pacemakers to interact with MRI machines in a manner that could affect the device function or patient safety. According to estimates, 50-75 percent of patients worldwide with implanted cardiac devices are expected to need an MRI scan during the lifetime of their devices.¹

Advisa MRI  –An Advanced Pacing System

Medtronic’s new pacing system provides patients with innovative exclusive technology, such as MVP^® (Managed Ventricular Pacing), which is proven to reduce unnecessary ventricular pacing by 99 percent², and complete automaticity, including Ventricular and Atrial Capture Management (VCM and ACM) and automatic sensing.  Advisa MRI includes sophisticated therapies such as Anti-Tachycardia Pacing (ATP) and diagnostics such as the Cardiac Compass Report™ and tachyarrhythmia management tools that assist in the early detection and termination of atrial fibrillation (AF).

Advisa MRI offers remote follow-up via the Medtronic CareLink^® Network, which transmits comprehensive arrhythmia and diagnostic device data to a physician’s clinic. In addition, the Advisa MRI pacemaker features OptiVol^® Fluid Status Monitoring, which, together with the Heart Failure Management Report, tracks and reports fluid changes using intrathoracic impedance measurements. These measurements may be used to detect potential fluid buildup before heart failure symptoms appear and also are available on Medtronic CareLink Network, enabling a fluid status check from a patient’s home.

Other therapies provided by Advisa MRI include the Rate Drop Response that identifies abrupt cardiac slowing and responds by pacing the heart at an elevated rate, which may reduce the frequency of syncopal (fainting) episodes in patients with apparent cardioinhibitory vasovagal syncope. Advisa MRI also provides high upper tracking rates up to 210 beats per minute (bpm), which may be beneficial for pediatric patients, as well as older active patients.
