Continuous variables are expressed as mean?±?standard deviation; age is expressed as median with range; HFpEF, heart failure with preserved ejection fraction; HCM, hypertrophic cardiomyopathy; LV, left ventricle; EDV: end-diastolic volume; ESV, end-systolic volume; EF, ejection fraction; m, male; f, female; y, years; LAV max, maximum left atrial volume; LAV min, minimum left atrial volume; LAV p-ac, left atrial volume prior to atrial contraction.
*Mitral regurgitation (MR) as defined by visual appearance of a regurgitation jet on cine SSFP.
