[Clinical and instrumental predictors of survival in patients with chronic heart failure and intact systolic left ventricle function]. / Kliniko-instrumental'nye prediktory vyzhivaemosti bol'nykh s khronicheskoi serdechnoi nedostatochnost'iu i sokhranennoi sistolicheskoi funktsiei levogo zheludochka.

165 patients with clinically-manifested chronic heart failure (CHF) and preserved (ejection fraction--EF > 40%) left ventricular (LV) systolic function have been investigated. 135 of them have ischaemic heart disease (IHD) and high blood pressure, 8 patients are without IHD and 22 patients with normal blood pressure. 62 patients have chronic atrial fibrillation. Survival value in patients with CHF and preserved LV systolic function was compared to survival value of those with CHF and impaired ejection fraction (EF < 40%). Patients with preserved LV systolic function have been found to be with better survival value than those with impaired ejection fraction (68 and 33% accordingly).
