“…In another study, Marvin-Peek et al observed that baseline step count was associated with the risk of future hospitalization in PAH patients during two years of follow-up. The median step count for hospitalized PAH patients was 3899 steps per day compared with 5367 steps per day in those who did not need hospitalization [ 20 ]. We chose a cut-off value of 5000 steps per day for the present study because we hypothesized that the number of steps around 5000 per day might predict hospitalization and death for PAH patients.…”

“…The number of 5000 steps per day was established to distinguish between low physical activity and moderate–high-activity subgroups. The number of steps around this value was a predictor of hospitalization in PAH patients [ 20 ] and a predictor of death in chronic heart failure patients [ 21 ]. Medical records were reviewed to obtain information about the demographic characteristics of the patients, their clinical conditions, and the treatment they had received.…”

One of the non-pharmacological recommendations for stable patients with pulmonary arterial hypertension (PAH) is to increase physical activity. The study aimed to analyze the degree of physical activity of PAH patients and check if mental factors may have a potential negative impact during the COVID-19 pandemic. Forty patients with stable PAH were included in the study. Physical activity was assessed by pedometer (Omron HJ-321-E) for four weeks. At baseline, in addition to the 6 min walk test (6MWT) and functional assessment, patients completed the quality-of-life questionnaire SF-36, fear of COVID-19 scale, and hospital anxiety and depression scale (HADS). The mean age of the study group was 45.5 years, 80% were women, and 62.5% had idiopathic/heritable PAH. Low physical activity defined as <5000 steps/day had 19 (47.5%), and moderate/high physical activity (≥5000 steps/day) had 21 (52.5%) patients. Patients with low physical activity less frequently worked compared with the moderate–high-activity sub-group, 42% vs. 81%, p = 0.03, and had the shorter distance in 6-6MWT, p = 0.03. There was no significant correlation between steps/day and different mental factors. Almost half of the study group had low activity during the pandemic. Mental factors did not impact physical activity in PAH patients during the pandemic.

“…Patients with pulmonary hypertension are physically inactive, associated with a higher risk of hospitalization 26 . Moreover, as physical inactivity may be one of the main drivers of lower-limb muscle weakness in patients with pulmonary hypertension, measuring physical activity levels seems of clinical importance 27 , 28 .…”

Patients with pulmonary hypertension present limited tolerance to exercise and aerobic capacity, which is reflected in the reduction in peak oxygen consumption and functional performance. This intolerance to exercise has traditionally been attributed to cardiac and respiratory dysfunction. However, as it happens in other chronic diseases, lower-limb and respiratory muscle alterations are also involved in patients with pulmonary hypertension. Increasing evidence suggests that physical exercise training is an efficient and safe strategy. The recommendation for light and moderate-intensity exercise is made within the framework of pulmonary rehabilitation, and its benefits have been previously described. In diseases such as COPD, lower-limb muscle function, exercise tolerance and quality of life improve following exercise training. And just as with COPD, it is necessary to promote evidence-based interventions with pulmonary hypertension. This narrative review focuses on the evaluation, safety and efficacy of training the respiratory muscles and the muscles of upper and lower extremities in patients with pulmonary hypertension.

“…However, prior studies in PAH have shown high sedentary times, [13][14][15] and there are limited data on the correlation between activity and PAH metrics 16 or hospitalizations. 17 We recently showed the variability in measurements using two different types of activity trackers worn at the same time in patients with PAH, 18 which further emphasizes the gaps in our knowledge about activity measures in PAH. Instead of collecting large amounts of data for 7 days and relying on proprietary algorithms to calculate activity time and steps, a remote 6MWT seems like a reasonable, objective alternative to assess patients.…”
