Annals of translational medicine, 6(11).2305-58472305-5839http://hdl.handle.net/11268/7355Pulmonary hypertension (PH) leads to exercise capacity impairment, but limited data are available on the objective evaluation of physical activity (PA) levels in these patients. Methods We assessed PA levels using triaxial accelerometry in Spanish PH patients (n=75, 48±14 years, 65% female) and gender/age matched controls (n=107), and examined potential associations of meeting minimum international recommendations [moderate-vigorous PA (MVPA) ≥150 min/week] with survival predictors. Results With the exception of vigorous PA (with very low values in both groups), all accelerometry data showed significant differences between patients and controls, with lower PA levels and proportion of individuals meeting minimum PA guidelines, but higher inactivity time, in the former. Notably, the odds ratio (OR) of having a “low-risk” value of 6-minute walking distance (≥464 m) or ventilatory equivalent for carbon dioxide (≤39) was higher in patients following MVPA guidelines than in their less active peers [OR =4.3, 95% confidence interval (CI), 1.6–11.6, P=0.005, and OR =4.5, 95% CI, 0.9–21.1, P=0.054]. Conclusions Daily PA is reduced in patients with PH, often to a level that may decrease their odds of survival. Efforts should be made to promote the implementation of healthy PA habits in this patient population.engPulmonary hypertensionjournal article10.21037/atm.2018.05.37restricted accessEjercicio FísicoAparato respiratorioAparato respiratorioDeporteTratamiento médico
