Additive beneficial effects of beta blockers in the prevention of symptomatic heart failure.

Unlabelled: The prevention of symptomatic heart failure represents the treatment of patients in the A and B stages of AHA/ACC heart failure classification. Stage A refers to patients without structural heart disease but at risk to develop chronic heart failure. The major risk factors in stage A are hypertension, diabetes, atherosclerosis, family history of coronary artery disease and history of cardiotoxic drug use.

[Physical exercise and sport activities in patients with and without coronary heart disease].

Methods: We studied 100 patients with chest pain, 78 men and 22 women, not older than 65 years, admitted to a coronary care unit.
