*Adjustment for CVRF is defined as age, sex, systolic blood pressure, LDL-cholesterol, smoking status, diabetes and family history of premature cardiovascular disease.
CVRF, cardiovascular risk factors; GLS, global longitudinal strain; LA, left atrium; LAVI, left atrial volume index; LDL, low density lipoprotein; LV, left ventricle; LVEF, left ventricular ejection fraction; RV, right ventricle; TAPSE, tricuspid annular plane systolic excursion.
