The severity of coronary artery stenosis which leads to myocardial infarction (MI) has been a matter of controversy. Historical data are in favor of mild luminal stenosis (<50% diameter stenosis) while recent studies suggest hemodynamically-significant coronary stenosis as the main substrate for subsequent MI. Also, mechanical stress resulted from coronary ...

Mitral annular plane systolic excursion (MAPSE) has been suggested as a parameter for left ventricular (LV) function. This review describes the current clinical application and potential implications of routinely using MAPSE in patients with various cardiovascular diseases. Reduced MAPSE reflects impaired longitudinal function and thus provides complementary information to ejection ...

Functional mitral regurgitation (FMR) is thought to be linked with ventricular afterload. However, the relation between aortic stiffness, which is a main determinant of ventricular afterload, and quantitatively assessed mitral regurgitation is unknown. A total of 175 patients (age 61 ± 13; 85 % male) with left ventricular (LV) systolic dysfunction were studied ...

Low-flow, low-gradient (LF-LG) aortic stenosis (AS) may occur with depressed or preserved left ventricular ejection fraction (LVEF), and both situations are among the most challenging encountered in patients with valvular heart disease. In both cases, the decrease in gradient relative to AS severity is due to a reduction in transvalvular ...

Renal function is a strong predictor of adverse events in heart failure. Current renal function measures are imperfect, and cystatin C (CysC) is promoted as a better marker of glomerular filtration rate. This study compares the prognostic use of CysC and derived glomerular filtration rate estimates with other measures of ...

Over a half century ago in Circulation, Dr. Paul Wood aptly described aortic stenosis (AS) as "a simple mechanical fault which, if severe enough, imposes a heavy burden on the left ventricle and sooner or later overcomes it"(1). Our subsequent understanding of the pathophysiology of AS, with more sophisticated tools ...
