Left ventricular systolic and diastolic function in coronary artery disease: effects of revascularization on exercise-induced ischemia.
Left ventricular systolic and diastolic function were studied before and after surgical revascularization in a group of 24 patients with stable angina who all had an excellent clinical response to surgery. With use of micromanometer left ventricular pressure measurements and ventricular volumes, calculated from biplane cineangiograms, left ventricular function at rest and during exercise before...
متن کاملEffects of coronary venous pressure on left ventricular diastolic distensibility.
Coronary arterial pressure and flow are known to influence left ventricular (LV) diastolic distensibility, but the influence of coronary venous pressure is unknown. To test the hypothesis that increased coronary venous pressure leads to an increase in LV wall volume and a decrease in LV diastolic distensibility, we studied excised, blood-perfused LV isovolumic dog hearts without the pericardium...
متن کاملAcute effects of ethanol on left ventricular diastolic function.
Transmitral flow velocities were measured by Doppler echocardiography in nine healthy men who ingested 1 g/kg of ethanol within one hour. The measurements were made before the first drink and every hour thereafter for three hours. The peak mean (SE) blood ethanol concentration was 21.4 (1.0) mmol/l. Each man was also studied after drinking fruit juice. Ethanol increased the heart rate but did n...
متن کاملIntra-aortic balloon pumping: effects on left ventricular diastolic function.
OBJECTIVE The intra-aortic balloon pump is the most widely used form of temporary cardiac assist and often utilised in patients before and after cardiac surgery. Several effects of balloon counter-pulsation have been reported previously, but its effect on left ventricular diastolic function has not been thoroughly investigated. The aim of this study is to examine the effect of the intra-aortic ...
متن کاملModulating Left Ventricular Diastolic Function
Although both dopamine and dobutamine are potent positive inotropic agents, multiple studies indicate that dopamine may produce a rise in left ventricular (LV) filling pressure, while dobutamine often has the opposite effect. To ascertain the pharmacological and hemodynamic mechanisms responsible for the elevation in LV filling pressure observed with dopamine, we administered incremental infusi...
