Implantable defibrillator therapy and mortality in patients with non-ischaemic dilated cardiomyopathy : An updated meta-analysis and effect on Dutch clinical practice by the Task Force of the Dutch Society of Cardiology.

BACKGROUND: Primary prophylactic implantable cardioverter-defibrillators (ICDs) in patients with non-ischaemic cardiomyopathy (NICMP) remains controversial. This study sought to assess the benefit of ICD therapy with or without cardiac resynchronisation therapy (CRT) in patients with NICMP. In addition, data were compared with real-world clinical data to perform a risk/benefit analysis. METHODS: Relevant randomised clinical trials (RCTs) published in meta-analyses since DANISH, and in PubMed, EMBASE and Cochrane databases from 2016 to 2020 were identified. The benefit of ICD therapy stratified by CRT use was assessed using random effects meta-analysis techniques. RESULTS: Six RCTs were included in the meta-analysis. Among patients without CRT, ICD use was associated with a 24% reduction in mortality (hazard ratio [HR]: 0.76; 95% confidence interval [CI]: 0.62-0.93; P = 0.008). In contrast, among patients with CRT, a CRT-defibrillator was not associated with reduced mortality (HR: 0.74, 95% CI 0.47-1.16; P = 0.19). For ICD therapy without CRT, absolute risk reduction at 3­years follow-up was 3.7% yielding a number needed to treat of 27. CONCLUSION: ICD use significantly improved survival among patients with NICMP who are not eligible for CRT. Considering CRT, the addition of defibrillator therapy was not significantly associated with mortality benefit compared with CRT pacemaker.

URGENT 1.5: diagnostic accuracy of the modified HEART score, with fingerstick point-of-care troponin testing, in ruling out acute coronary syndrome.

BACKGROUND: The HEART score is a validated risk stratification tool for chest pain patients presenting to the emergency department and was recently investigated for implementation in a pre-hospital setting. Fingerstick (capillary blood) point-of-care (POC) troponin testing enables quick measurements outside the hospital and seems easier to implement than the current venous blood sampling techniques. This study investigates the diagnostic accuracy of the modified HEART score, integrating fingerstick POC troponin testing, in ruling out acute coronary syndrome (ACS). METHODS: The data of 96 patients with chest pain, included in a study investigating a novel POC troponin device under development at the cardiac emergency department, were analysed retrospectively. Based on the patients' admission data and capillary POC high-sensitivity troponin I (hs-cTnI) results, the modified HEART score was determined. The outcome measure, for evaluating the diagnostic accuracy of the modified HEART score, was the occurrence of ACS. RESULTS: Of the total study population, 33 patients (34%) were diagnosed with ACS. Seventeen patients (18%) were classified as low risk (0-3 points) and one patient (6%) in this group was diagnosed with ACS. The sensitivity and negative predictive value of the modified HEART score was 97.0 and 97.6%, respectively. CONCLUSION: The modified HEART score, integrating capillary POC hs-cTnI results, is a promising tool for ruling out ACS in patients with chest pain presenting to the cardiac emergency department. These results encourage prospective investigation into the integration of fingerstick POC troponin testing in the modified HEART score in a pre-hospital setting.

Ischaemia with no obstructive coronary arteries.

Ischaemia with no obstructive coronary arteries (INOCA) is a common ischaemic heart disease with a female preponderance, mostly due to underlying coronary vascular dysfunction comprising coronary microvascular dysfunction and/or epicardial coronary vasospasm. Since standard ischaemia detection tests and coronary angiograms are not suitable to diagnose coronary vascular dysfunction, INOCA is often overlooked in current cardiology practice. Future research, including large outcome trials, is much awaited. Yet, adequate diagnosis is possible and treatment options are available and vital to reduce symptoms and most probably improve cardiovascular prognosis. This review intends to give a brief overview of the clinical presentation, underlying pathophysiology, and the diagnostic and treatment options in patients with suspected INOCA.

Off-site primary percutaneous coronary intervention in a new centre is safe: comparing clinical outcomes with a hospital with surgical backup.

OBJECTIVES: To evaluate the procedural and clinical outcomes of a new primary percutaneous coronary intervention (PPCI) centre without surgical back-up (off-site PCI) and to investigate whether these results are comparable with a high volume on-site PCI centre in the Netherlands. BACKGROUND: Controversy remains about the safety and efficacy of PPCI in off-site PCI centres. METHODS: We retrospectively analysed clinical and procedural data as well as 6­month follow-up of 226 patients diagnosed with ST-elevated myocardial infarction (STEMI) who underwent PPCI at VieCuri Medical Centre Venlo and 115 STEMI patients who underwent PPCI at Catharina Hospital Eindhoven. RESULTS: PPCI patients in VieCuri Medical Centre had similar procedural and clinical outcomes to those in Catharina Hospital. Overall there were no significant differences. The occurrence of procedural complications was low in both groups (8.4 % VieCuri vs. 12.3 % Catharina Hospital). In the VieCuri group there was one procedural-related death. No patients in either group needed emergency surgery. At 30 days, 17 (7.9 %) patients in the VieCuri group and 9 (8.1 %) in the Catharina Hospital group had a major adverse cardiac event. CONCLUSION: Performing PPCI in an off-site PCI centre is safe and effective. The study results show that the procedural and clinical outcomes of an off-site PPCI centre are comparable with an on-site high-volume PPCI centre.

The first year of the Venlo percutaneous coronary intervention program: procedural and 6-month clinical outcomes.

OBJECTIVES: Analysis of the first results of off-site percutaneous coronary interventions (PCI) and fractional flow reserve (FFR) measurements at VieCuri Medical Centre for Northern Limburg in Venlo. BACKGROUND: Off-site PCI is accepted in the European and American Cardiac Guidelines as the need for PCI increases and it has been proven to be a safe treatment option for acute coronary syndrome. METHODS: Retrospective cohort study reporting characteristics, PCI and FFR specifications, complications and 6-month follow-up for all consecutive patients from the beginning of off-site PCI in Venlo until July 2012. If possible, the data were compared with those of Medical Centre Alkmaar, the first off-site PCI centre in the Netherlands. RESULTS: Of the 333 patients, 19 (5.7 %) had a procedural complication. At 6 months, a major adverse cardiovascular event (MACE) occurred in 43 (13.1 %) patients. There were no deaths or emergency surgery related to the PCI or FFR procedures. There was no significant difference in occurrence of a MACE or adverse cerebral event between the Alkmaar and Venlo population in the 30-day follow-up. CONCLUSION: This study demonstrates off-site PCI at VieCuri Venlo to have a high success rate. Furthermore, there was a low complication rate, low MACE and no procedure-related mortality.

Design and rationale of the NetherLands registry of invasive Coronary vasomotor Function Testing (NL-CFT).

BACKGROUND: Angina without angiographic evidence of obstructive coronary artery disease (ANOCA) is a highly prevalent condition with insufficient pathophysiological knowledge and lack of evidence-based medical therapies. This affects ANOCA patients prognosis, their healthcare utilization and quality of life. In current guidelines, performing a coronary function test (CFT) is recommended to identify a specific vasomotor dysfunction endotype. The NetherLands registry of invasive Coronary vasomotor Function testing (NL-CFT) has been designed to collect data on ANOCA patients undergoing CFT in the Netherlands. METHODS: The NL-CFT is a web-based, prospective, observational registry including all consecutive ANOCA patients undergoing clinically indicated CFT in participating centers throughout the Netherlands. Data on medical history, procedural data and (patient reported) outcomes are gathered. The implementation of a common CFT protocol in all participating hospitals promotes an equal diagnostic strategy and ensures representation of the entire ANOCA population. A CFT is performed after ruling out obstructive coronary artery disease. It comprises of both acetylcholine vasoreactivity testing as well as bolus thermodilution assessment of microvascular function. Optionally, continuous thermodilution or Doppler flow measurements can be performed. Participating centers can perform research using own data, or pooled data will be made available upon specific request via a secure digital research environment, after approval of a steering committee. CONCLUSION: NL-CFT will be an important registry by enabling both observational and registry based (randomized) clinical trials in ANOCA patients undergoing CFT.

Purulent pericarditis, an uncommon entity in modern practice: a case report.

We report an 82-year-old female with pneumococcal pneumonia. Antimicrobial therapy was started in an early stage of the disease. On the 10th day of admission she developed peripheral pitting oedema with elevated jugular venous pressure and a drop in blood pressure. Her electrocardiogram showed sinus tachycardia and concave upward ST-segment elevation in almost all leads. A transthoracic two-dimensional echocardiogram revealed a large circumferential pericardial effusion, with diastolic collapse of the right atrium and a mitral inflow pattern that suggested cardiac tamponade. Emergency pericardiocentesis was performed, releasing 600 cc of thick green purulent material, followed by good haemodynamic recovery. The haemodynamic state, pneumonic infiltrate and inflammatory parameters responded gradually to antimicrobial therapy and the patient recovered and was discharged after six weeks. We conclude that even susceptible strains of Streptococcus pneumonia in a patient with no predisposing factors may still cause purulent pericarditis, even in the era of adequate antibiotic therapy.

Delays in the treatment of patients with acute coronary syndrome: Focus on pre-hospital delays and non-ST-elevated myocardial infarction.

Delays in patients suspected of acute coronary syndrome (ACS) should be kept as short as possible to reduce complications and mortality. In this review we discuss the substantial pre-hospital delays of ST-elevated myocardial infarction (STEMI) patients as well as non-STEMI patients. The pre-hospital delays include patient, doctor and emergency medical transport (EMT) delay. Patient delay is among the longest in the pre-hospital chain of ACS patients. Interventions as mass media campaigns or individual education programs have not yet shown much improvement. Patients with chest pain most often contact the general practitioner (GP) instead of the recommended EMT, increasing delays as well. To decrease the delays by referring all patients promptly and without restriction to the emergency department (ED) is not feasible. Up to 80% of the patients with chest pain do not have a cardiac diagnosis and thus referral of all these patients would result in overcrowding of the ED. Triage is therefore crucial. Triage of patients with chest pain is therefore imperative and there is a great need of (validated) triage tools.

Safety and feasibility of prehospital thrombolysis in combination with active rescue PCI strategy for acute ST-elevation myocardial infarction.

BACKGROUND/OBJECTIVES: The purpose of this observational study was to provide an impression of the outcomes of prehospital thrombolysis in combination with an active coronary angioplasty intervention (PCI) strategy for acute ST-elevation myocardial infarction. METHODS: In a group of 151 consecutive patients the following parameters were measured: time delay, percentage of reperfusion, reocclusion, stroke, death, need for PCI and the number of protocol violations. RESULTS: The diagnosis by the ambulance paramedics was made in 8±6 minutes, followed by thrombolysis in 13±7 minutes (median±SD). In 2% (3) of the patients the thrombolytic agent was erroneously administered without complications. The elapsed time from onset of symptoms to treatment was a median of 112±77 minutes. Five percent (7) of the patients died in the first 30 days and 2% (3) suffered an intracerebral haemorrhage. Reperfusion was documented in 76% (112) of the patients, from which 18% (20) reoccluded in the following 24 hours. In patients where reperfusion was not established or reocclusion occurred, patients underwent rescue/facilitated PCI: in total 37% (55 patients). After three months 9% (13) of the patients had severly impaired (EF <40%) left ventricular function. CONCLUSION: In our region, we successfully implemented the prehospital thrombolysis system achieving a competitive call-to-needle time and reperfusion rate. The percentage of patients who violated the protocol, suffered an intracerebral haemorrhage, died and/or had severely impaired left ventricular function was acceptable.

Posterolateral defect of the normal human heart investigated with nitrogen-13-ammonia and dynamic PET.

UNLABELLED: The posterolateral defect is a common artifact seen when static 13N-ammonia imaging with PET is used to assess myocardial perfusion. The aim of this study was to compare dynamic and static. 13N-ammonia PET and to obtain more insight into the cause of the posterolateral defect. METHODS: Dynamic 13N-ammonia PET was performed in 19 healthy nonsmoking volunteers at rest. Perfusion was assessed in the early phase of the study using a curve fit method over the first 90 sec. Nitrogen-13 accumulation (static PET) was assessed 4 to 8 min after injection. Each study was normalized to a mean of 100. The average distribution of normalized perfusion and activity was calculated in 24 segments. Heterogeneity of both activity and perfusion distribution were assessed and the activity distribution was compared with perfusion distribution. RESULTS: Perfusion distribution was homogeneous, with the exception of the inferior and apical regions. Activity distribution was inhomogeneous, with a lower activity in the posterolateral and apical regions. In the whole left ventricle, significant differences in distribution were found between static and dynamic imaging. CONCLUSION: Perfusion distribution was significantly different on dynamic images compared to static images. The posterolateral defect was not found on dynamic images. The posterolateral defect and other inhomogeneities in activity distribution are caused by tracer-dependent features, probably a redistribution of metabolites of 13N-ammonia.

Quantitative myocardial mapping of perfusion and metabolism using parametric polar map displays in cardiac PET.

UNLABELLED: Most efficacy studies of cardiac PET in demonstrating myocardial ischemia and viability have been performed using one or more transversal static images of the heart. In contrast, in this paper we describe a method of functional imaging of the complete left ventricular myocardium for perfusion with nitrogen-13-ammonia, both at rest and during a dipyridamol stress test, and of glucose metabolism with 18F-fluorodeoxyglucose (18FDG). METHODS: This was performed by using the data of each of 48 radial segments of 10 short-axis images as tissue data and LV cavity data of three basal planes as blood pool data. The study describes the results of 19 normal volunteers and 36 patients with coronary artery disease. From the data of the normal volunteers a 95% normal confidence interval was calculated for each imaging modality. These intervals were then used to describe the patient data as normal, ischemic or infarcted. RESULTS: The results of analysis of the parametric images was compared with the results of static analysis of the same patient data and found to be less dependant on the detection threshold used. CONCLUSION: The described method enables the routine application of functional PET imaging of the total myocardium by the semi-automatic construction of parametric flow and metabolism polar maps. It thus provides an increased performance in the diagnosis, quantification and localization of myocardial ischemia and viability over conventional PET imaging.

A mathematical model for the heterogeneity of myocardial perfusion using nitrogen-13-ammonia.

UNLABELLED: Heterogeneity of left ventricular myocardial perfusion is an important clinical characteristic. Different aspects of this heterogeneity were analyzed. METHODS: The coefficient of variation (v), characterizing heterogeneity, was modeled as a function of the number of segments (n), characterizing spatial resolution of the measurement, using two independent pairs of mutually dependent parameters: the first pair describes v as a power function of n, and the second pair adds a correction for n small. n was varied by joining equal numbers of neighboring segments. Local similarity of the perfusion was characterized by the correlation between the perfusions of neighboring segments. Genesis of the perfusion distribution was modeled by repeated asymmetric subdivision of the perfusion into a volume among two equal subvolumes. These analyses were applied to study the differences between 16 syndrome X patients and 16 age- and sex-matched healthy volunteers using 13N-ammonia parametric PET perfusion data with a spatial resolution of 480 segments. RESULTS: The heterogeneity of patients is higher for the whole range of spatial resolutions considered (2 < or = n < or = 480; for n = 480, v = 0.22 +/- 0.03 and 0.18 +/- 0.02; p < 0.005). This is because the first pair of parameters differs between patients and volunteers (p < 0.005), whereas the second pair does not (p > 0.1). For both groups of subjects there is a significant positive local correlation for distances up to 30 segments. This correlation is a formal description of the patchy nature of the perfusion distribution. CONCLUSION: When comparing values of v, these should be based on the same value of n. The model makes it possible to calculate v for all values of n < or = 480. Mean perfusion together with the two pairs of parameters are necessary and sufficient to describe all aspects of the perfusion distribution. For n small, heterogeneity estimation is less reliable. Patients have a higher heterogeneity because their perfusion distribution is more asymmetrical from the third to the seventh generation of subdivision (8 < or = n < or = 128). Therefore, a spatial resolution of n > or = 128 is recommended for parametric imaging of perfusion with PET. Patients have only a very slightly more patchy distribution than volunteers. The differences in perfusion between areas with low perfusion and areas with high perfusion is larger in patients.

Comparison between positron emission tomography myocardial perfusion imaging and intracoronary Doppler flow velocity measurements at rest and during cold pressor testing in angiographically normal coronary arteries in patients with one-vessel coronary artery disease.

With use of invasive methods, coronary endothelial function is generally studied by examining the response of epicardial coronary arteries to intracoronary administered acetylcholine or to cold pressor testing. Because invasive methods have substantial inherent limitations, studies should attempt to evaluate coronary endothelial function noninvasively. This study examines a noninvasive technique for endothelium-related coronary stress testing. In myocardial regions supplied by nonstenotic coronary arteries, we compared positron emission tomography (PET) myocardial perfusion imaging with intracoronary Doppler flow velocity measurements during endothelium-related stress testing. PET perfusion was examined at rest and during cold pressor testing in 10 patients with 1-vessel coronary artery disease. In nonstenotic coronary arteries, flow velocity measurements were obtained at rest, during cold pressor testing, and during intracoronary administered acetylcholine. Perfusion and flow velocity responses and stress/rest ratios were compared between the techniques during the various circumstances. Positive correlations were found between: (1) cold pressor Doppler flow velocity responses and acetylcholine Doppler flow velocity responses (r = 0.84, SEE = 0.19, p = 0.003); (2) cold pressor PET perfusion responses and cold pressor Doppler flow velocity responses (r = 0.70, SEE = 0.17, p = 0.02); and (3) cold pressor PET perfusion responses and acetylcholine Doppler flow velocity responses (r = 0.62, SEE = 0.19, p = 0.05). These results suggest that in angiographically normal coronary arteries, both the flow velocity and the perfusion responses during cold pressor testing may be related to the response to acetylcholine.

Uptake of radioligands by rat heart and lung in vivo: CGP 12177 does and CGP 26505 does not reflect binding to beta-adrenoceptors.

The biodistribution of (-)-4-(3-t-butylamino-2-hydroxypropoxy)-[5,7-3H-benzimidazol-2-one (CGP12177, a non-selective beta-adrenoceptor antagonist) and 1-[2-(3-carbamoyl-4-hydroxy)-(5-3H-phenoxy)]-2-propanol methanesulfonate, (CGP26505, a beta 1-adrenoceptor antagonist) was studied in rats pretreated with various alpha- and beta-adrenoceptor blocking drugs (5 min before 3H injection, in dosages at which the drugs demonstrated the expected selectivity). Cardiac and pulmonary radioactivity were measured after 10 min, when specific binding was maximal. Uptake of [3H]CGP12177 was linked to binding to beta-adrenoceptors since it was not affected by prazosin or yohimbine, and was equally well inhibited by propranolol, unlabelled CGP12177 and isoprenaline. Moreover, atenolol and CGP20712A inhibited [3H]CGP12177 uptake in heart (predominantly beta 1-adrenoceptors) more potently than ICI 118,551, while in lungs (predominantly beta 2-adrenoceptors) ICI 118,551 was more potent than atenolol or CGP20712A. In contrast, [3H]CGP26505 uptake in the target organs was equally effectively inhibited by propranolol and ICI 118,551, and significantly lowered by alpha-adrenoceptor antagonists. We conclude that [11C]CGP12177, but not [11C]CGP2605 will be suitable for positron emission tomography imaging of beta-adrenoceptors in animals.

Late onset atrioventricular nodal tachycardia.

AV nodal tachycardia may present at any age, but onset in late adulthood is considered uncommon. To evaluate whether onset of AV nodal tachycardias at older age is related to organic heart disease (possibly setting the stage for re-entry due to degenerative structural changes) 32 consecutive patients with symptomatic AV nodal tachycardia were studied. The age at onset of attacks showed a bimodal pattern, with 2 peaks: one between 15 and 35 years (22 patients) and one around 55 years (10 patients). Significantly more older patients had an underlying heart disease (60% versus 14%, P < 0.01), with coronary artery disease in 4 and hypertensive heart disease in 3. Frequent supraventricular ectopic activity was seen during baseline 24-h ambulatory monitoring in all the older patients, versus in only half of the younger patients (P = 0.005). These results indicate that late onset AV nodal tachycardia (i.e. > age 45 years) is not infrequent (33%). The frequent supraventricular arrhythmias on one hand and age-related structural AV nodal changes, potentially enhanced by underlying heart disease on the other, both may contribute to the development of late onset re-entrant AV nodal tachycardia.

Autoperfusion balloon catheter for complicated coronary angioplasty: a prospective study with retrospective controls.

Prolonged angioplasty balloon inflation with an autoperfusion balloon for failed conventional coronary angioplasty, was compared with emergency surgery for this condition. Restenosis was assessed 6 weeks after successful intervention with the autoperfusion balloon. Forty consecutive patients with persistent acute occlusion and/or severe intimal dissection during conventional angioplasty, were treated with the autoperfusion balloon. They were candidates for emergency surgery if it failed. Total inflation time was significantly longer (p < 0.001) with the autoperfusion balloon (27.5; 10-180 min) than with the standard balloon (10; 1-20 min) (median; range). The number of inflations was significantly lower (p < 0.001) with the autoperfusion balloon (2; 1-5 times) than with the standard balloon (5; 2-14 times) (median; range). Two patients died, one before surgery could be performed. The autoperfusion balloon was successful in 26 patients (65%). After 6 weeks, 16 (62%) were asymptomatic without anti-anginal medication, 24 underwent repeat angiography, 10 (42%) had restenosis, 7 (27%) underwent elective bypass surgery. Emergency surgery remained necessary in 13 patients (33%), 9 received arterial grafts. In 31 retrospective controls, who had undergone immediate surgery for the same indication, only venous grafts could be used. Thus, prolonged autoperfusion balloon inflation was successful in 65% of the cases of failed, conventional angioplasty. The angiographic restenosis rate after 6 weeks was 42%. If emergency surgery remained necessary, the autoperfusion balloon facilitated the use of arterial bypass grafts.

Comparison of thallium scintigraphy and positron emission tomography.

Assessment of tissue viability has become an important issue in recent years. Scintigraphic measurements have provided important diagnostic, therapeutic, and prognostic information in patients with myocardial dysfunction, who may improve in left ventricular function after revascularization. For detection of regional myocardial ischemia and viability, thallium 201 (201Tl) has been the most widely used tracer in single-photon scintigraphy. However, 201Tl scintigraphy may underestimate regional viability, especially after myocardial infarction. Positron emission tomography (PET) provides an advanced imaging technology that permits the accurate definition of regional tracer distribution. In combination with nitrogen (13N) ammonia, PET allows for the sensitive and specific detection of coronary artery disease. Several studies indicate the superiority of this approach in comparison with standard 201Tl tomographic (SPECT) imaging. In addition, regional blood flow can be accurately measured with 13N ammonia PET, and this approach can be employed in conjunction with pharmacologic stress imaging to quantify regional flow reserve. In combination with metabolic markers, such as fluorine 18 (18F) deoxyglucose, an indicator of glucose uptake, PET is capable of assessing myocardial viability. Furthermore, the PET approach may differentiate between various forms of cardiomyopathy. More studies are needed to define the cost-benefit ratio of both the 201Tl reinjection and the PET technique for the management of patients with coronary artery disease or cardiomyopathy.

Hemolysis in fresh human blood with a new hemoperfusion pump to prevent myocardial ischemia during coronary angioplasty.

A new, 5 ml, piston type hemoperfusion pump, designed to prevent myocardial ischemia during coronary angioplasty, was evaluated in vitro at different flow rates. The driving pressures necessary to achieve the different flow rates and biochemical indicators of hemolysis, were assessed. Fresh human blood was perfused through 2 angioplasty catheter types, one with distal side holes and another catheter type without side holes but with a tapered distal segment. Despite high driving pressures, shear stress > 200 Pa, turbulent flow and the presence of occlusive valves in the pump, hemolysis proved to be minimal. This is most readily explained by the short period of time during which the blood was subjected to mechanical factors that cause hemolysis. Additionally, the volume of the pump, and hence the amount of blood subjected to mechanical hemolysis, was small. The side holes in the catheter caused obstruction by promoting the formation of clots.

Effectiveness of a physiotherapeutic exercise programme for chronic heart failure patients.

BACKGROUND: This pilot study was conducted to evaluate the design and effects of a physiotherapeutic exercise programme on exercise capacity, muscle strength and quality of life in patients with chronic heart failure. METHODS: Eighteen patients with chronic heart failure were randomly assigned to either a training group (n=9) participating in a physiotherapeutic exercise programme or a regular care control group (n=9). At baseline and after three months patients underwent a maximal bicycle test, a six-minute walk test, a respiratory test, three muscle strength tests and a number of questionnaires pertaining to quality of life. RESULTS: Compared with the control group, a positive trend in the results of the training group was found. All measures showed a greater increase in the intervention group than in the control group. In five measures the difference was significant: 1. distance covered during the six-minute walk test (p=.036), 2. Borg rating of perceived exertion after this walk test (p=.006), 3. 'care and housekeeping' of the activities daily life questionnaire (p=.004), 4. 'symptoms' (p=.048) and 5. 'quality of life' (p=.040) of the Kansas City Cardiomyopathy Questionnaire. CONCLUSION: The study in chronic heart failure patients suggests both that the design of our training programme is workable and that our physiotherapeutic exercises produce positive effects. Further research with more patients is necessary to generalise these results to the population of patients with stable chronic heart failure. To assess the long-term effects of the programme, follow-up research is necessary.
