Effect of long-term therapy with contemporary drugs on diastolic cardiac function in patients with chronic heart failure.

摘要

Bisoprolol, carvedilol, enalapril are widely used for the treatment of patients with chronic heart failure. Definite role in the treatment of these patients is also played by angiotensin-II receptor blockers. Diastolic left ventricular function is widely spread among patients with chronic heart failure and its important value for prognosis has been demonstrated. However effect of modern drugs used for the treatment of chronic heart failure has been poorly studied. We assessed effects of enalapril, its combination with bisoprolol, carvedilol, and irbesartan on parameters of diastolic function in a randomized prospective controlled study on 84 patients with NYHA class III-IV heart failure and left ventricular ejection fraction <40%. It has been shown that left ventricular dysfunction is highly prevalent in patients with chronic heart failure and that differentiated approach to the choice of a drug for the treatment of chronic heart failure requires consideration of the type of diastolic dysfunction.
