Brugada syndrome presenting as an acute coronary syndrome.

Syncope, non-specific ST-segment alterations and elevated troponin (cTn) are suspicious of an acute coronary syndrome (ACS). While an ACS is excluded when the coronary angiogram returns normal, the raised cTn should prompt a search for other potentially lethal diseases, such as pulmonary embolism, myocarditis or malignant ventricular arrhythmias. Here we describe a 42-year-old man presenting with syncope, ST-segment elevation, cTn rise and a normal angiogram.

Training adherence in early cardiac rehabilitation: EFFECT OF EXERCISE SESSION DURATION.

Purpose: The aim of this study was to analyze the effect of the prolongation of exercise sessions (from 40 to 60 minutes) on training adherence in the rehabilitation of patients with coronary artery disease (CAD).

Methods: In this prospective, randomized clinical trial, 417 CAD patients (mean age = 63 +/- 10 years, 78% males) followed a 7-week exercise training intervention, 3 sessions each week, at 65% of the maximal oxygen uptake capacity. Subjects were randomly assigned to 40-minute (n = 198) or 60-minute (n = 219) exercise sessions, with equal time distribution on the different exercise modalities (42%-treadmill, 33%-bike, and 25%-arm cranking device, in each session).
