The Role of Hypotension as a Factor of Unfavorable Prognosis in Patients With Chronic Heart Failure

Despite obvious achievements during last decades in studies of pathogenesis and search for effective ways of treatment of chronic heart failure (CHF) it remains one of most severe and prognostically unfavorable diseases of the cardiovascular system. Thereby determination of predictors of death and detection of high risk patients for more active drug interventions on CHF progression appears to be actual. It has been shown in a number of epidemiological and cohort studies that low arterial pressure (AP) serves as an independent risk factor of prognosis in patients with CHF. In this paper we present short literature review on this theme, consideration of possible mechanisms of negative effect of arterial hypotension on function of vitally important organs in patients with CHF, and summation of data of studies which have demonstrated relationship between low level of AP and worsening of prognosis.
