Effects of 12-month therapy with a beta1-adrenoblocker atenolol on the process of late postinfarction remodeling of the heart and parameters of intracardiac hemodynamics were assessed in an open noncomparative study on 55 survivors of macrofocal myocardial infarction. Therapy with atenolol was associated with: (1) reduction of myocardial hypertrophy in patients with increased left ventricular myocardial mass without effect on its volume, cavity geometry and global systolic function; (2) normalization of initially 'hypertrophic' type of transmitral blood flow. Affecting mainly the demand component of the myocardial oxygen supply/demand ratio atenolol promoted inclusion of hibernating cardiomyocytes into active contraction.
