Fractional systolic pressure and fractional diastolic pressure are reciprocal indices of pulsatility in the aorta

The severity of coronary artery disease evaluated by central systolic pressure and fractional diastolic pressure

BACKGROUND Central pulse pressure, pulse pressure index and fractional pulse pressure have been confirmed to be associated with increased risk of cardiovascular disease, but if the severity of cardiovascular disease, specifically for the coronary artery disease, is evaluated by central systolic pressure and fractional diastolic pressure has been not well studied. AIMS This study was designed ...

The Impact of Cardiac Rehabilitation on Pulmonary Artery Systolic Pressure and Left Ventricular End-Diastolic Pressure in Patients after Coronary Artery Bypass Graft Surgery

Background:Cardiac rehabilitation program (CRP) is a useful method of modifying cardiovascular risk factors, improving life expectancy and quality of life in patients with ischemic heart disease (IHD). The present study was conducted to evaluate the effects of cardiac rehabilitation on the pulmonary artery systolic pressure (PASP) and left ventricular end-diastolic pressure (LV...

Ventricular pressure-volume curve indices change with end-diastolic pressure.

Many indices have been proposed to describee the diastolic pressure-volume curve mathematically and permit quantification of the elastic properties of the myocardium itself in hopes that changes in the muscle caused by disease would b.e reflected in the diastolic pressure-volume curve. To date, none of the proposed indices has been shown convincingly to discriminate one group of patients from a...

Ventricular pressure-volume curve indices with end-diastolic pressure.

Systolic and diastolic pressure relationships in the isolated rat heart.

I 1956, Bloom 1 observed that the excised beating rat heart with atria removed was capable of filling and emptying itself repeatedly and was able to propel itself in liquid. Somewhat later, Bloom and Ferris' showed that there develops during systole a positive pressure in the left ventricle of the excised heart beating in liquid and that there is produced a negative intraventricular pressure du...
