The aim is to analyze pulmonary arterial pressure at rest and during exercise in patients with chronic mountain sickness.
Systematic review of studies published in English or Spanish before June 2018.
Nine studies with a total of 287 participants were included in the meta-analysis.
Echocardiographic estimations of pulmonary arterial pressure were analyzed at rest and during mild exercise.
Mean systolic pulmonary arterial pressure at rest was estimated at 27.9 mmHg (95% CI 26.3–29.6 mmHg).
At rest, pulmonary arterial pressure was 11% higher in chronic mountain sickness patients compared to healthy high-altitude dwellers.
During mild exercise (50 W), mean systolic pulmonary arterial pressure was 48.3 mmHg in patients versus 36.3 mmHg in high-altitude dwellers.
