[Hemodynamics in viral-bacterial pneumonia in middle-aged patients].

Clinico-instrumental investigations were performed in 52 patients with virus-bacterial pneumonia in different periods of disease and 10-12 mos after discharge from hospital. Considerable changes in the hemodynamics of the lesser and greater circulation and left ventricular myocardial contractility preserving for a long time, particularly in a grave form of disease, were revealed. In long-term periods hypertension in the pulmonary artery system persisted. It could result in the occurrence of occult heart failure.
