Left atrial contribution to ventricular filling during the course of evolving heart failure.
BACKGROUND Abnormal left ventricular (LV) filling has been observed in patients with heart failure and is characterized by marked heterogeneity of mitral inflow velocity. In the present study, the contribution of the left atrium to LV filling was examined in eight dogs during the course of evolving heart failure. METHODS AND RESULTS Heart failure was produced by multiple sequential intracoron...
متن کاملChronic Left Ventricular Heart Failure
The effect of the vasodilator prazosin vs placebo on exercise duration until marked dyspnea, and on left ventricular function measured by echocardiography, was evaluated in a double-blind, randomized study in 24 patients with chronic left ventricular failure despite digitalis and diuretic therapy. Compared with the double-blind placebo, prazosin reduced resting systolic and diastolic blood pres...
متن کاملLeft ventricular remodelling in systolic heart failure using ivabradine. Slower is smaller is better?
Tardif and co-workers have published the echocardiographic substudy of the SHIFT trial. This pre-defined substudy included 611 out of 6505 patients from SHIFT, or, in other words, 9.3% of the entire cohort studied in SHIFT. The authors report that of these 611 patients, 96 ivabradineand 104 placebo-treated patients had to be excluded, mainly due to incomplete or unreadable echo recordings, whic...
متن کاملPredictors of left ventricular remodelling and failure in right ventricular pacing in the young
AIMS To identify risk factors for left ventricular (LV) dysfunction in right ventricular (RV) pacing in the young. methods and results: Left ventricular function was evaluated in 82 paediatric patients with either non-surgical (n = 41) or surgical (n= 41) complete atrioventricular block who have been 100% RV paced for a mean period of 7.4 years. Left ventricular shortening fraction (SF) decreas...
متن کاملTime course of sympathovagal imbalance and left ventricular dysfunction in conscious dogs with heart failure.
To elucidate the time course of sympathovagal balance and its relationship to left ventricular function in heart failure, we serially evaluated left ventricular contractility and relaxation and autonomic tone in 11 conscious dogs with tachycardia-induced heart failure. We determined a dynamic map of sympathetic and parasympathetic modulation by power spectral analysis of heart rate variability....
