Abstract
Background Postacute sequelae of COVID‐19 (PASC) and HIV are both associated with reduced exercise capacity, but whether SARS‐CoV‐2 or PASC are associated with exercise capacity among people with HIV (PWH) is unknown. We hypothesized that PWH with PASC would have reduced exercise capacity from chronotropic incompetence. Methods and Results We conducted cross‐sectional cardiopulmonary exercise testing within a COVID recovery cohort that included PWH with and without prior SARS‐CoV‐2 infection and people without HIV with prior SARS‐CoV‐2 infection (controls). We evaluated associations of HIV, SARS‐CoV‐2, and PASC with exercise capacity (peak oxygen consumption) and chronotropy (adjusted heart rate reserve). We included 83 participants (median age, 54 years; 35% women; 37 PWH): 23 out of 37 (62%) PWH and all 46 controls had prior SARS‐CoV‐2 infection, and 11 out of 23 (48%) PWH and 28 out of 46 (61%) without HIV had PASC. Peak oxygen consumption was reduced among PWH versus controls (80% predicted versus 99%, P=0.005), a difference of 5.5 mL/kg per minute (95% CI, 2.7–8.2; P
