Myocardial metabolism during increased work states in the porcine left ventricle in vivo.
It is not known whether myocardial energy requirements can be increased to the degree that they exceed myocardial O2 availability in the absence of abnormalities of coronary blood flow or coronary reserve. To determine whether this form of "demand ischemia" occurs, 10 swine were subjected to pressure overload induced by aortic constriction, inotropic and chronotropic stimulation by dobutamine, ...

متن کاملIncreased Regional Myocardial StiEfness of the Left Ventricle During Pacing-induced Angina in Man
The left ventricular diastolic pressure-volume.relationship shifts upward during angina, but why this happens is not known. To assess regional myocardial stiffness, we studied 12 patients who.had coronary artery disease using simultaneous left ventricular micromanometer pressure recording and Mmode echocardiography before and during angina induced. by pacing tachycardia. All patients had twoor ...

متن کاملMyocardial regeneration after implantation of porcine small intestinal submucosa in the left ventricle
INTRODUCTION Most cardiomyocytes do not regenerate after myocardial infarction. Porcine small intestinal submucosa has been shown to be effective in tissue repair. OBJECTIVE To evaluate myocardial tissue regeneration and functional effects of SIS implantation in pigs after left ventriculotomy. METHODS Fifteen pigs were assigned to two groups: porcine small intestinal submucosa (SIS) (N=10) ...
