[The prognostic assessment of the reversibility of myocardial dysfunction in patients with ischemic heart disease after aortocoronary bypass].

Forty-six patients with ischemic heart disease with considerable dysfunction of the myocardium were subjected before operation of aortocoronary shunting to veloergometry with calculation of indices of the central hemodynamics by the method of tetrapolar rheoplethysmography, echocardioscopy before and after taking nitroglycerin. Close interrelation was noted between the increase of the stroke volume during veloergometry, increased fraction of output after taking nitroglycerin and improved contractile capacity of the myocardium after aortocoronary shunting.

[The treatment of patients with ischemic heart disease and significant disorder of left ventricular function].

A study is presented of 71 patients with ischemic heart disease verified coronarographically and showing severe disorders of contractile function of the left ventricle. Thirty-eight patients who underwent the operation of aortocoronary shunting showed an improvement of the contractile capacity of the myocardium, and a longer survival as compared with those treated medically. Medical treatment was accompanied by more complications in the form of myocardial infarctions, cardiac insufficiency resulting often in a lethal outcome.

[The hemostatic system and the status of aortocoronary venous autografts in patients with ischemic heart disease after surgery for direct myocardial revascularization based on autopsy research data].

The study was undertaken to examine the relationship between the major hemostatic factors in the early postoperative period and the status of an autovenous graft in 19 patients with coronary heart disease who died 3 to 40 days after aortocoronary bypass surgery. The hemostatic system was monitored on the patients' admission and during the whole observation. Hypercoagulation was recorded in all patients in the first postoperative hours.

[Myocardial function in patients with a history of infectious-allergic myocarditis].

A echocardiographic study of the functional state of the myocardium 4-8 years after a history of infectious-allergic myocarditis in 67 patients revealed in 7.5% a moderate reduction of the contractile capacity of the myocardium and in 4.5% initial signs of left ventricle hypertrophy.
