Pulmonary arterial pressure during rest and exercise in healthy subjects: a systematic review.
According to current guidelines, pulmonary arterial hypertension (PAH) is diagnosed when mean pulmonary arterial pressure (Ppa) exceeds 25 mmHg at rest or 30 mmHg during exercise. Issues that remain unclear are the classification of Ppa values <25 mmHg and whether Ppa >30 mmHg during exercise is always pathological. We performed a comprehensive literature review and analysed all accessible data...
متن کاملCarotid baroreflex control of arterial blood pressure at rest and during dynamic exercise in aging humans.
The arterial baroreflex is fundamental for evoking and maintaining appropriate cardiovascular adjustments to exercise. We sought to investigate how aging influences carotid baroreflex regulation of blood pressure (BP) during dynamic exercise. BP and heart rate (HR) were continuously recorded at rest and during leg cycling performed at 50% HR reserve in 15 young (22 ± 1 yr) and 11 older (61 ± 2 ...
متن کاملEffects of age on pulmonary artery systolic pressure at rest and during exercise in normal adults.
AIMS The aim of this study was to explore the range of pulmonary artery systolic pressure (PASP) at rest and with exercise in healthy individuals of various ages, as most studies assumed PASP > 35 mmHg with exercise as the upper limits of normal. METHODS AND RESULTS Seventy healthy volunteers, with a good continuous wave Doppler tricuspid regurgitation signal at rest, underwent quantitative D...
متن کاملRight ventricular pressure/volume relationship at rest and during exercise in patients with chronic lung disease.
In most circumstances in health, efficient alveolar ventilation and alveolar-to-arterial exchange of 02 and CO2 are among the strongest of links in the gas-transport chain during maximal exercise. Indeed, in most instances, the metabolic cost of ventilation represents the only significant contribution ofthe pulmonary system to the limitation of 02 transport to locomotor muscles and thus to the ...
متن کاملPulmonary Congestion at Rest and Abnormal Ventilation During Exercise in Chronic Systolic Heart Failure
BACKGROUND In patients with chronic heart failure, abnormal ventilation at cardiopulmonary testing (expressed by minute ventilation-to-carbon dioxide production, or VE/VCO2 slope, and resting end-tidal CO2 pressure) may derive either from abnormal autonomic or chemoreflex regulation or from lung dysfunction induced by pulmonary congestion. The latter hypothesis is supported by measurement of pu...
