Matrix of correlations between the clinical variables and left ventricular systolic and diastolic function

Variable	BMI	Age	Systolic BP	Diastolic BP
p < 0.05; p < 0.01; **p < 0.001.
A, maximum velocity of active mitral filling; AA, area of velocity of active mitral filling; AE, area of velocity of passive mitral filling; BMI, body mass index; BP, blood pressure; DS, deceleration slope; E, maximum velocity of passive mitral filling; EF, ejection fraction; EP, ejection period; FS, fractional shortening; IVRT, isovolumetric relaxation time; LAD, left atrial diameter; LV, left ventricular; MV½12T, mitral valve pressure half-time; PEP, pre-ejection period; VCS, mean velocity of circumferential shortening.
