RESUMEN
BACKGROUND: Exercise training is included in cardiac rehabilitation programs to enhance physical capacity and cardiovascular function. Among the existing rehabilitation programs, exercises in water are increasingly prescribed. However, it has been questioned whether exercises in water are safe and relevant in patients with stable chronic heart failure (CHF), coronary artery disease (CAD) with normal systolic left ventricular function. The goal was to assess whether a rehabilitation program, including water-based gymnastic exercises, is safe and induces at least similar benefits as a traditional land-based training. METHODS AND RESULTS: Twenty-four male CAD patients and 24 male CHF patients with stable clinical status participated in a 3-week rehabilitation. They were randomized to either a group performing the training program totally on land (CADl, CHFl; endurance + callisthenic exercises) or partly in water (CADw, CHFw; land endurance + water callisthenic exercises). Before and after rehabilitation, left ventricular systolic and cardiorespiratory functions, hemodynamic variables and autonomic nervous activities were measured. No particular complications were associated with both of our programs. At rest, significant improvements were seen in CHF patients after both types of rehabilitation (increases in stroke volume and left ventricular ejection fraction [LVEF]) as well as a decrease in heart rate (HR) and in diastolic arterial pressure. Significant increases in peaks VO(2), HR, and power output were observed in all patients after rehabilitation in exercise test. The increase in LVEF at rest, in HR and power output at the exercise peak were slightly higher in CHFw than in CHFl. CONCLUSIONS: Altogether, both land and water-based programs were well tolerated and triggered improvements in cardiorespiratory function.

Background Exercise training as part of a comprehensive cardiac rehabilitation is recommended for patients with cardiac heart failure. It is a valuable method for the improvement of exercise tolerance. Some studies reported a similar improvement with quadricipital electrical myostimulation, but the effect of combined exercise training and electrical myostimulation in cardiac heart failure has not been yet evaluated in a large prospective multicentre study. Purpose The aim of this study was to determine whether the addition of low frequency electrical myostimulation to exercise training may improve exercise capacity and/or muscular strength in cardiac heart failure patients. Methods Ninety-one patients were included (mean age: 58 ± 9 years; New York Heart Association II/III: 52/48%, left ventricular ejection fraction: 30 ± 7%) in a prospective French study. The patients were randomised into two groups: 41 patients in exercise training and 50 in exercise training + electrical myostimulation. All patients underwent 20 exercise training sessions. In addition, in the exercise training + electrical myostimulation group, patients underwent 20 low frequency (10 Hz) quadricipital electrical myostimulation sessions. Each patient underwent a cardiopulmonary exercise test, a six-minute walk test, a muscular function evaluation and a quality of life questionnaire, before and at the end of the study. Results A significant improvement of exercise capacity (Δ peak oxygen uptake+15% in exercise training group and +14% in exercise training + electrical myostimulation group) and of quality of life was observed in both groups without statistically significant differences between the two groups. Mean creatine kinase level increased in the exercise training group whereas it remained stable in the combined group. Conclusions This prospective multicentre study shows that electrical myostimulation on top of exercise training does not demonstrate any significant additional improvement in exercise capacity in cardiac heart failure patients.

Cardiovascular mortality has decreased over the past 25 years, largely because of acute coronary syndrome care and preventive actions. Nevertheless, the rate of coronary heart disease remains high, with an annual risk of 4.7% (cardiac mortality, myocardial infarction, stroke). Cardiovascular risk factor management must be a priority in primary and secondary prevention, to improve the prognosis of this severe disease, in which absence of symptoms does not mean benignity. The current goals of therapeutic patient education are smoking cessation, regular physical activity, a cardioprotective (Mediterranean) diet, management of stress, good treatment adherence (which improves compliance), judicious use of the care system and help with occupational reintegration. Current and future programmes must be in accordance with the Haute Autorité de Santé recommendations published in 2007.

PURPOSE: The aim of this study was to evaluate the predictive factors of return to work after coronary bypass graft surgery, for the subgroup of professionally active patients aged less than 60 years included in the PERISCOP study. METHODS: In the principal, prospective, multicentre study, 2065 patients were evaluated 20+/-10 days after surgery by exercise testing, echocardiogram and 24-h ambulatory ECG monitoring. A questionnaire was completed one year after surgery. We studied a subgroup of this population, consisting of 530 patients previously defined (94.5% men; mean age: 50.5+/-5.8 years). RESULTS: One year after surgery, five of these patients had died and 21 were lost to follow-up. Among the remaining patients, 340 patients (67.5%) had returned to work. Forty patients (7.9%) had retired, 45 (8.9%) were on sick leave, 22 (4.4%) were unemployed, 49 (9.7%) returned to work after the deadline of 12 months, eight (1.6%) had given insufficient information on return to work. In multivariate analysis, the independent predictors of a failure to return to work were age >51 years [OR: 0.39 (95% CI: 0.25-0.59)], being a manual worker [OR: 0.49 (95% CI: 0.31-0.79)], being from South East France [(OR: 0.42 (95% CI: 0.23-0.74)], presence of angina [OR: 0.40 (95% CI: 0.20-0.82)], dyspnoea [(OR: 0.46 (95% CI: 0.28-0.77)] and a duration of exercise <420 s [(OR: 0.50 (95% CI: 0.33-0.76)]. CONCLUSIONS: Return to work after coronary bypass graft surgery is observed in 67.5% of cases and depends essentially on socio-professional factors and residual symptoms. A regional effect was also observed, which requires further study.

AIMS: Little is known about which patients who have undergone coronary bypass surgery are at risk of future clinical cardiovascular events and may benefit from further medical treatment. We sought to determine if routine non-invasive cardiac investigations performed early after surgery were able to stratify the risk of cardiovascular events in this population. METHODS: Two thousand and sixty-five consecutive patients were enrolled in a prospective multicenter study (PERISCOP). Exercise testing, echocardiography, and 24-h ambulatory ECG monitoring were performed at day 20+/-10 after coronary bypass surgery. Follow-up was performed 1 year after coronary bypass surgery. Causes of all hospitalisation and death occurring within 1 year were documented and classified by an End-point Committee. The principal endpoint was the combination of all-cause deaths and cardiovascular events requiring hospitalisation (myocardial infarction, unstable or severe angina, stroke, congestive heart failure). RESULTS: The 1-year frequency of first events was 155 (8%). In multivariate analysis, exercise duration <420s (RR=1.68; 95% CI: 1.13-2.49), exercise induced ST segment depression >1mm (RR=1.90; 95% CI: 1.18-3.05), and left ventricular (LV) dysfunction (wall motion index <1.15) (RR=1.97; 95% CI: 1.10-3.51) were independent predictors of cardiovascular events and deaths. Ambulatory ECG monitoring had no predictive value. CONCLUSIONS: Exercise testing and echocardiography performed early after coronary bypass surgery are able to identify high-risk patients who may benefit from intensive secondary prevention.
