Pulmonary artery and left heart end-diastolic pressure relations.

The exponential fall of the pulmonary pressure curve from its systolic peak to left atrial pressure previously described in the presence of normal intraventricular conduction has been investigated in patients with right bundle-branch block. We have been able to show once more that the pulmonary artery diastolic pressure seeks the left atrial level: when right ventricular systole is delayed the ...

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...

Relationship between pulmonary artery end-diastolic pressure and left ventricular filling pressure in patients in shock.

Bedside catheterization permitted 56 simultaneous measurements of left ventricular end-diastolic pressure (LVEDP) and pulmonary artery end-diastolic pressure (PAEDP) in 25 patients in shock. Measurements were made over a wide range of heart rates (60-160 beats/min), arterial oxygen tension (P02; 33-562 mm Hg), stroke volumes (9-105 ml), and systolic arterial pressures (65-250 mm Hg), and before...

Effects of open heart surgery on end-diastolic pressure-diameter relations of the human left ventricle.

Curves relating left ventricular end-diastolic pressure (LVEDP) to echocardiographically determined end-diastolic diameter (LVEDD) were obtained before and after ischemic arrest in 15 patients during open heart surgery. LVEDP ranged from 0-20 mm Hg during routine operation of the heart-lung machine. Ischemic arrest ranged from 0-94 minutes. In eight patients averaging 21 ± 7 (SEM) minutes of ar...

Relationship of the pulmonary artery end-diastolic pressure to the left ventricular end-diastolic and mean filling pressures in patients with and without left ventricular dysfunction.

The relationship of the left ventricular end-diastolic pressure (LVEDP) and the pulmonary arterial "wedge" mean pressure (PAWMP) to the pulmonary artery enddiastolic pressure (PAEDP) was investigated by cardiac catheterization in 71 subjects. Pressure records were obtained simultaneously or immediately consecutively. In 15 subjects with normal LV function (LVEDP, 4 to 12 mm Hg) PAEDP was within...
