Five-year mortality for stable angina in a medical practice study and a randomized trial.

Objective: Evolution of revascularization and medical therapy has increased the probability of improved survival in patients with stable angina. The present investigation tests the hypothesis that medical practice will generate lower mortality than randomly assigned bypass surgery in the European Coronary Surgery Study (ECSS) two decades earlier.

Method: Using eligibility criteria of ECSS, a clinical decision strategy (CDS) cohort of 362 patients was selected from a nationwide study of medical practice in Sweden.

Atrial septal defect in adults. Thirty-eight-year follow-up of a surgically and a conservatively managed group.

This report describes the long-term (up to 38 years) outcome, in terms of mortality and cardiovascular morbidity, in a non-randomized clinical observation study of a surgically and a conservatively managed group of adult patients with shunt lesions at atrial level. Haemodynamic status was assessed at baseline and at repeat examination. Twelve patients underwent surgical repair of the lesion between these two heart catheterizations, resulting in a marked reduction in heart size and right ventricular systolic pressure.

The role of early surgery following myocardial infarction. European Coronary Surgery Bypass Group.

This co-operative study was a prospective randomised study to evaluate the role of coronary bypass surgery following acute myocardial infarction. The criterion for entry was an early positive exercise tolerance test. All patients who satisfied the clinical criteria of acute myocardial infarction but who were excluded had information on survival obtained after two years.
