The medical value and cost-effectiveness of an exercise test for sport preparticipation evaluation in asymptomatic middle-aged white male and female athletes.

Background: Cardiovascular events related to high-intensity sport practice are rare but dramatic. Coronary artery disease (CAD) is the leading cause of these events after the age of 35 years. The value of a maximal exercise test (ET) for detection of athletes at risk remains a matter of debate.

Antiarrhythmic drug-induced side effects: a prospective survey of 300 patients.

The purpose of this study was to define the characteristics and the frequency of antiarrhythmic drug-induced side effects. All patients referred for cardiological consultation and treated with antiarrhythmic drugs between April 1992 and October 1993 were prospectively investigated. 300 patients were included in the study: 41 (13.

Benefits of physical activity in the prevention of cardiovascular diseases.

Today it is undisputed that physical exercise and sports activity have beneficial effects in the prevention of cardiovascular diseases. Heberden, who in 1772 brilliantly described the clinical manifestations of angina pectoris, anticipated the benefits of physical exercise when he asked whether "chopping wood for 30 min every day would not be a remedy." These beneficial effects have been demonstrated in primary and in secondary prevention after a heart attack or coronary event.

[Isoforms of creatine kinase and myoglobin in myocardial infarct treated by thrombolysis].

The isoforms of creatinine kinase (CK) and myoglobin were analysed by serial samplings in 45 patients admitted consecutively for myocardial infarction treated by thrombolysis according to the usual indications. Angiographic controls were carried out systematically in the first 24 hours, including 20 cases at the end of thrombolysis. The patients were divided into two groups according to the patency of the infarct related artery: Group I (n = 35) with a patent vessel and Group II (n = 10) with an occluded vessel; 4 patients in Group II were successfully revascularised by angioplasty.

[Infarction in patients aged over 70. Apropos of 194 patients].

Among 498 patients hospitalised for myocardial infarction during a three year period, 194 (39%) were aged over 70 (mean age: 78.6 +/- 6), including 99 women and 95 men. Comparison of this group of patients with those aged under 70 showed a significantly higher hospital mortality (17.
