Abstract

The elevation in pulmonary artery pressure and in left ventricular enddiastolic pressure in ischemic heart disease is partially caused by an increased ventricular stiffness [1,3,5]. Nitroglycerin does not only immediately alleviate angina, it also induces a reduction of ventricular stiffness at rest (Fig. 1). We have previously shown that this improvement of ventricular stiffness could be due to a reduction of ischemia caused by a decrease in myocardial oxygen consumption [6] We have now investigated whether improvement of ischemia after coronary bypass surgery would result in a similar change of ventricular stiffness.
