  • Background: The interaction of the heart with the systemic vasculature, termed ventricular-arterial coupling, is a central determinant of net cardiovascular performance in normal and pathological conditions. Ventricular and arterial elastance can be easily assessed by echocardiography, both at rest and during stress. Aim: To assess noninvasively left ventricular-arterial coupling in healthy and diseased subjects at rest and during dipyridamole (DIP) stress. Materials and methods: We enrolled 365 patients (63±16 years; 231 males) referred to stress echo lab: 131 \"normals\" (Nl); 86 patients with coronary artery disease, 68 with negative (CAD, SE -) and 18 with positive (CAD, SE+) stress echo; 148 with idiopathic dilated cardiomyopathy (DCM). In all, ventricular-arterial coupling was indexed by the ratio of ventricular force (Systolic Pressure/End-Systolic Volume index) to arterial elastance (EaI, ratio of end-systolic pressure by stroke volume). 2D echo (for ESV and stroke volume) and cuff sphygmomanometer (systolic pressure, multiplied x 0.90 to obtain end-systolic pressure) provided the raw measurements. Results: At rest, EaI was profoundly increased in DCM (6.3±4.4; p.001 vs. all other groups: Nl (literal)
