OBJECTIVE To evaluate the correlation between feature tracking-derived measurements of the right ventricular myocardium and gestational age in healthy fetuses. METHODS Global and segmental longitudinal peak systolic strain, strain rate and velocity values of the right ventricular myocardium were assessed by a novel feature-tracking technique in 150 healthy fetuses at between 13 and 39 weeks' ...
BACKGROUND Two-dimensional strain echocardiography detects early signs of left ventricular dysfunction; however, it is unknown whether myocardial strain analysis at rest in patients with suspected stable angina pectoris predicts the presence of coronary artery disease (CAD). METHODS AND RESULTS In total, 296 consecutive patients with clinically suspected stable angina pectoris, no previous ca...
AIMS The efficacy of anthracyclines is undermined by potential life-threatening cardiotoxicity. Cardiotoxicity is dependent upon several factors and the timing to its development is variable. Moreover, as adjuvant therapy with trastuzumab often follows, a close monitoring of cardiac function in those treated with anthracyclines is mandatory. Left ventricular ejection fraction (LVEF) by echocard...
AIMS The purpose of this study was to test the hypothesis that left ventricular (LV) mechanical dyssynchrony deteriorates the longitudinal systolic and diastolic function of the left ventricle (LV) in patients with heart failure with a normal LV ejection fraction (HFNEF). METHODS AND RESULTS In patients with HFNEF and in a control group consisting of asymptomatic patients with LV diastolic dy...
BACKGROUND Advanced age is related to left ventricular (LV) remodeling. We sought to investigate the relationships between aging, elevated hemodynamic load, cardiac mechanics, and LV remodeling in an elderly community-based population. METHODS AND RESULTS We studied 1105 subjects (76±5 years, 61% women) without prevalent heart failure, who attended the visit 5 of the ARIC study (Atheroscleros...
BACKGROUND Albuminuria is a marker of endothelial dysfunction and has been associated with adverse cardiovascular outcomes. The reasons for this association are unclear but may be attributable to the relationship between endothelial dysfunction and intrinsic myocardial dysfunction. METHODS AND RESULTS In the Hypertension Genetic Epidemiology Network (HyperGEN) Study, a population- and family-...
