diastolic phase of cardiac function is associated with lower arterial flow and hence higher concentration of intra arterially injected drug is achieved at the site of injection. it is herein postulated that drugs show higher efficacy when injected during the diastolic phase of cardiac function. it is also postulated that this benefit cannot be achieved when the drug is injected with higher rate...

Diastolic phase of cardiac function is associated with lower arterial flow and hence higher concentration of intra arterially injected drug is achieved at the site of injection. It is herein postulated that drugs show higher efficacy when injected during the diastolic phase of cardiac function.

In this study, a method for non-invasive estimation of stress on the heart wall in  the diastole phase is presented using ultrasound echocardiography and tissue Doppler  imaging. The aim of this study was to evaluate the stress on the heart wall as a  pre-diagnosis  to identify people with coronary artery stenosis. 29 patients with stenosis of more than 70%, 30 patients with stenosis of 50 to 7...
