Abstract

To stydy the parameters of preload, afterload, and contractility of the heart, we evaluated 10 mitral stenosis, 5 mitral stenoinsufficiency, and 5 mitral stenosis with aortic insufficiency by measuring the external energy potential, external mechaical work, and external energy potential to PVa(Pressure-volume Area) ratio with non-invasive method, echocardiography and carotid pulse tracting. The results are summarized as follows; 1) External energy potential of mitral stenosis was significantly higher than that of MSI or MS with AI. 2) External mechanical work of MSI or MS with AI was significantly higher than that of Ms. 3) External energy potential to PVA ratio was signifiantly higher in the MS, but there was no significantly difference between the MSI and MS with AI. According to the above results, external energy potential to PVA ratio with echocardiogram and carotid pulse tracting was good parameters of preload, afterload, and contractility. And this method may used bed-side monitoring in the clinical area.
