Pulmonary artery pressure limits exercise capacity at high altitude.
Altitude exposure is associated with decreased exercise capacity and increased pulmonary vascular resistance (PVR). Echocardiographic measurements of pulmonary haemodynamics and a cardiopulmonary exercise test were performed in 13 healthy subjects at sea level, in normoxia and during acute hypoxic breathing (1 h, 12% oxygen in nitrogen), and in 22 healthy subjects after acclimatisation to an al...

Another point with regard to the PASP measurement of the patients in this study was made of tricuspid regurgitant jet. At the same time, the mean tricuspid regurgitant jet velocity was 1.7 ± 0.5 m/s in the patient population. When this value was analyzed, it gave the impression that sufficient flow was not obtained over the tricuspid valve. For this reason, since guidelines recommend to use con...
متن کاملClinical correlates of pulmonary artery systolic pressure.
Systolic Pressure To the Editor: In their study of echocardiographically normal subjects, Dr McQuillan et al demonstrated an independent association of age, male sex, and body mass index (BMI) with elevated pulmonary artery systolic pressures (PASPs).1 The authors suggested that the correlation between increased BMI and increased PSAP may be attributable to an increased cardiac output in obese ...

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...
متن کاملEstimating mean pulmonary artery pressure from systolic pressure: a caveat?
I thank Drs. Hooper and Wilson for their comments on my article.1 I concur completely with Dr. Hooper’s sentiments. Dr. Wilson links conflicts that arise through a physician’s relationship with industry and a physician’s scientific interest in a topic (so-called academic conflict of interest). These issues have been conflated recently by physicians who have financial conflicts. The two are comp...
