A: Late diastolic mitral inflow velocity, ACEi: Angiotensin converting enzyme inhibitor, Afib: Atrial fibrillation, ARB: Angiotensin-II receptor blocker, DCM: Dilated cardiomyopathy, E: early diastolic mitral inflow velocity, e’: Early diastolic mitral annular velocity, GLS: Global Longitudinal Strain, IHD: ischemic heart disease, LVEF: Left ventricular ejection fraction, MD: Mechanical dispersion, MRA: Mineralocorticoid receptor antagonist, RV FWS: Right ventricular free wall strain, TAPSE: Tricuspid annular plane systolic excursion. This evidence concerns the gene ACE and coronary artery disorder.
