Clinical Study
End-Systolic Elastance and Ventricular-Arterial Coupling Reserve Predict Cardiac Events in Patients with Negative Stress Echocardiography
Figure 2
Ventricular-arterial coupling reserve, its components and hemodynamic changes during exercise, dipyridamole and dobutamine stress echocardiographies. Bars show changes form rest to peak stress (reserve) in the patients who underwent exercise (green bars), dipyridamole (yellow bars) and dobutamine (red bars) stress echocardiography. CAD: coronary artery disease; CI: cardiac Index; DC: dilated ischemic cardiomyopathy; DCM: idiopathic dilated cardiomyopathy; : arterial elastance index; : LV end-systolic elastance index; : ventricular-arterial coupling ratio; HYP: hypertensive; NL: normals; PVA: pressure-volume area; SVR: systemic vascular resistance; and TEST: diagnostic tests.
