Background: The prevalence and clinical outcomes of heart failure with preserved left ventricular ejection fraction after acute myocardial infarction have not been well elucidated.
Objective: To analyze the prevalence of heart failure with preserved left ventricular ejection fraction in acute myocardial infarction and its association with mortality.
Methods: Patients with acute myocardial infarction (n = 1,474) were prospectively included.

Objective: To assess the prevalence of ventricular arrhythmias induced by exercise in a population with sleep disorders and to analyze the triggering factors.
Methods: Patients were consecutively selected from the database of the Sleep Clinic of Universidade Federal de São Paulo. All subjects were submitted to basal polysomnography, blood sample collection, physical examination, 12-lead ECG, spirometry, cardiorespiratory exercise study on a treadmill, and echocardiogram.
Objective: To assess the changes in the medicamentous treatment of elderly patients hospitalized with acute myocardial infarction occurring over an 8-year period.
Methods: We retrospectively analyzed 379 patients above the age of 65 years with acute myocardial infarction who were admitted to the coronary unit of a university-affiliated hospital from 1990 to 1997. The patients were divided into 2 groups, according to the period of time of hospital admission as follows: group 1 - from 1990 to 1993; and group 2 - from 1994 to 1997.
