[Recurrent cardiac crises in patients with post-infarction cardiosclerosis].

Macrofocal myocardial infarction survivers with repeated cardiac accidents (sudden death and repeated myocardial infarction) in the post-infarction period (a 5-7-year follow-up) differ from similar patients with a stable course of the disease by a greater incidence and persistence of such risk factors as smoking and hyperlipoproteinemia. A thorough and maximally possible correction of these factors is necessary. Regular ergometric tests allow the identification of a high risk group for repeated cardiac accidents among patients with a history of an uncomplicated myocardial infarction. Of prognostic significance are such ergometric parameters as the cause of load cessation, the total displacement of the ST segment and the coefficient of consumption of the myocardial reserves. There has been no direct correlation between the incidence of ventricular arrhythmias revealed at the bicycle ergometric examination and the development of repeated cardiac accidents, which appears to be associated with the adequate symptomatic therapy aimed at maintaining the contractile function of the myocardium.
