The evaluation of left ventricular dyssynchrony in hypertensive patients with a preserved systolic function undergoing gated SPECT myocardial perfusion imaging

Predictors and outcomes of cardiac dyssynchrony among patients with heart failure attending Benjamin Mkapa Hospital in Dodoma, central Tanzania: A protocol of prospective-longitudinal study

“…Moreover, Nagueh et al in Nigeria found that mechanical dyssynchrony in heart failure patients was as high as 27% for those with narrow QRS complex, while it was as high as 78% for those with wide QRS complex [9]. Additionally, among patients with heart failure; 34% prevalence of mechanical dyssynchrony was found in individuals with QRS �120 mms, and 11.9% in those with QRS of �120ms [12]. In another study that was conducted in Ivory Coast, among patients with dilated cardiomyopathy, mechanical Dyssynchrony was estimated to be 70% for intraventricular Dyssynchrony and 47.5% for interventricular Dyssynchrony [13].…”

Value of early detection of left ventricular mechanical dyssynchrony for assessing long‐term outcomes

“…In a study that assessed the impact of early LVD after primary percutaneous coronary intervention, 91% of the patients with LVD developed LV remodeling compared to 2% in patients with no substantial LVD . Assessment of LVD may clinically be more important in patients who are at high risk for, but has not developed, overt heart disease . LVD was an independent predictor of cardiovascular death in a large study that included 1138 individuals from general population who were followed up for a median follow‐up of 11.1 years.…”
