β* indicates the changed value of NCP with a 1 unit increase of the determinant. NCP, normalized cardiac power; CI, confidence interval; HCM, hypertrophic cardiomyopathy; LV, left ventricle; BSA, body surface area; EDV, end-diastole volume; BMI, body mass index; EF, ejection fraction; CAD, coronary artery disease.
