Effects of exercise training after acute coronary syndromes in octogenarians - prospective 12-month evaluation.

OBJECTIVE: Aim: To demonstrate the impact of individual exercise training on the course of the disease, exercise tolerance and quality of life (QoL) in patients over 75 years after acute coronary syndrome (ACS). PATIENTS AND METHODS: Materials and methods: Study included octogenarians after ACS randomly assigned into two groups: a training group (ExT) subjected to individualized physical training and a control group (CG) with standard recommendations for activity. Patients underwent exercise tolerance test (ETT), 6-minute walk test (6-MWT), NHP and QoL questionnaires evaluation, lab tests, ECG, echocardiographic examination at the beginning and after 2, 6 and 12 months. RESULTS: Results: Study included 51 patients, mean age 80 years, 50% men, all patients completed the study. Initial physical capacity was comparable in both groups. After 2-month training the average ETT exercise time increased by 12.5% (p=0.0004), the load increased by 13% (p=0.0005) and the 6-MWT results improved by 8.3% (p=0.0114). Among CG these changes were not significant. But 6 and 12 months after training cessation 6-MWT results returned to the initial values (p=0.069, p=0.062 respecitvely). Average ETT exercise time and average load decreased significantly after 12 months (p=0.0009, p=0.0006). Level of pain was significantly lower at the end of the training in ExT group (p=0.007), but it returned to initial 12 months later (p=0.48). QoL deteriorated significantly in the ExT group 12 months after training cessation (p=0.04). CONCLUSION: Conclusions: Cardiac rehabilitation in octogenarians after ACS was safe and improved physical performance in a short period of time. Cessation of training resulted in a loss of achieved effects and deterioration of the QoL.

Improvement of exercise tolerance in cardiopulmonary testing with sustained safety after regular training in outpatients with systolic heart failure (NYHA III) and an implantable cardioverter-defibrillator. Prospective 18-month randomized study.

INTRODUCTION: The aim of the study was to evaluate the impact of individual training on the level of physical capacity and echocardiographic parameters in patients with systolic heart failure (SHF), NYHA III and an implantable cardioverter-defibrillator (ICD). MATERIAL AND METHODS: The study included 84 patients with SHF, randomly assigned to one of two groups: with regular training (ICD-Ex) and a control group (ICD-control). The ICD-Ex group participated in a hospital rehabilitation program which after discharge was individually continued for 6 months in an outpatient setting. The ICD-control group participated in a training program during hospitalization, but after discharge did not perform any controlled activities. Prior to discharge, at 6 and 18 months cardiopulmonary exercise testing (CPX), standard echocardiographic examination and the 6-minute walk test (6-MWT) were performed in all patients. RESULTS: After 18 months in the ICD-Ex group most of the CPX parameters improved significantly (VO2 peak, ml/kg/min: 13.0 ±4.1 vs. 15.9 ±6.1, p < 0.0017; VCO2 peak, l/min: 1.14 ±0.34 vs. 1.58 ±0.65, p < 0.0008; Watt: 74.5 ±29.7 vs. 92.6 ±39.1, p < 0.0006; METs 3.72 ±1.81 vs. 4.35 ±1.46, p < 0.0131). In the ICD-control group no significant improvement of any parameter was observed. Left ventricular systolic dimensions remained significantly lower at 18 months only in the ICD-Ex group (49.5 ±11.0 vs. 43.4 ±10.0, p < 0.011). Left ventricular ejection fraction in both groups significantly increased at 6 and 18 months compared to baseline (ICD-Ex: 25.07 ±5.4 vs. 31.4 ±9.2, p < 0.001, vs. 30.9 ±8.9, p < 0.002, ICD-C: 25.1 ±8.3 vs. 29.2 ±7.7, p < 0.012 vs. 30.1 ±9.1, p < 0.005). Distance of the 6-MWT was significantly improved after 6 and 18 months in the ICD-Ex group and was overall longer than in the ICD-control group (491 ±127 vs. 423 ±114 m, p < 0.04). CONCLUSIONS: An individual, 6-month training program, properly controlled in patients with SHF and an implanted ICD, was safe and resulted in a significant improvement of exercise tolerance and capacity and echocardiographic parameters.

The case of patient with advanced congestive heart failure, NYHA III, of ischaemic and valvular aetiology and concomitant diseases is presented. Introduction of 6-month, controlled physical training resulted in improvement of health status, exercise performance, ventilation and left ventricular function. Quality of life got significantly better. This aspect of treatment should be considered in majority of patients with heart failure.

Successful primary coronary angioplasty improves early and long-term outcomes in ST segment elevation acute coronary syndromes in patients above 80 years of age.

BACKGROUND: ST segment elevation myocardial infarction (STEMI) in patients above 80 years of age continues to be a therapeutic challenge. Patients in this age group are rarely included in randomised clinical trials. AIM: Comparison of the effectiveness and safety of STEMI management in octogenarians in hospitals with a 24-hour percutaneous coronary intervention (PCI) capability and hospitals without PCI access. METHODS: A retrospective analysis of medical records of 50 octogenarians who were treated with PCI (group 1) in one center and 50 patients treated noninvasively in the other 3 hospitals (group 2). We evaluated mortality and major adverse cardiac events after 10 days, 30 days and 1 year. RESULTS: There were no significant differences in the demographic characteristics of the study groups. The duration of coronary pain was similar in both groups: 318 min in group 1 vs 383 min in group 2 (NS). Mortality in group 2 was significantly higher than in group 1: 40% vs 14%, respectively, after 10 days (p = 0.0034); 48 vs 18% after 30 days (p = 0.0014); and 54% vs 24% after 1 year (p = 0.0021). Thrombolytic treatment was used in only 40% of the patients in group 2. In group 2, acute heart failure (HF) (Killip class III and IV) was diagnosed more frequently than in group 1 (28% vs 12%, p = 0.034). In patients with Killip class I/II HF, mortality in patients in group 2 and group 1 was 22% vs 9%, at 10 days; 31% vs 14% at 30 days; and 39% vs 20% at 1 year. In patients with Killip class III/IV HF, mortality was 86% vs 50%, at 10 days; 93% vs 50% at 30 days; and 93% vs 50% at 1 year, respectively (all differences NS). In multivariate analysis adjusted for the differences between groups, HF (a negative effect) and a successful PCI (a positive effect) were independent predictors of 1-year survival. CONCLUSIONS: Successful primary PCI in STEMI patients above 80 years of age resulted in a reduction of early and long-term mortality compared to the medically treated patients. The benefits of PCI treatment accrued during the follow-up. In patients treated in the tertiary reference centre in whom PCI was not successful or was not deemed feasible, prognosis was similar to that in the medically treated patients. The latter patients rarely received thrombolytic treatment.
