[The mass of the myocardium and tolerance for physical exercise in the postinfarct period in hypertension patients]. / Massa miokarda i perenosimost' fizicheskoi nagruzki v postinfarktnom periode u bol'nykh gipertonicheskoi bolezn'iu.

As many as 56 patients with stage-II hypertensive disease (HD) as per the WHO classification were examined. On day 30 of myocardial infarction (MI) the left ventricular myocardium mass was calculated and six months later exercise tolerance was evaluated using bicycle ergometer. The evaluation done showed that the presence of hypertrophy of the Left ventricle in HD patients by day 30 of MI was a prognostic sign of low exercise tolerance in postinfarction period, which fact permits exercise tolerability to be foreseen, and issues related to the patients' fitness for work to be settled as early as the hospital stage of rehabilitation of MI patients.
