Abstract

In this randomized, prospective monocentric study, 40 subjects with coronary artery disease or hypertension (cardiovascular disease [CVD] group) were assigned to either surgical mask (SM) or class 2 filtering facepiece mask (FFP2). They performed cycle ergometry exercise tests with progressive intensity until exhaustion with the assigned mask and another test with no mask (NM) in random order. A control group of 10 healthy subjects randomly performed 3 exercise tests with NM, SM, and FFP2, respectively. Blood pressure, heart rate, 12-lead electrocardiogram, exertion, shortness of breath, and capillary blood gases from the earlobe were documented. Across all groups, exercise testing with face masks resulted in a significantly reduced peak power output in watts compared with testing with NM (CVD group: SM vs NM: -5.0 ± 7.0%, p = 0.005; FFP2 vs NM: -4.7 ± 14%, p = 0.03; control group: SM vs NM: -6.8 ± 4.4%, p = 0.008; FFP2 vs NM: -8.9 ± 6.3%; p = 0.01) without differences in hemodynamic parameters, such as maximum heart rate and systolic blood pressure. Wearing an FFP2 compared with NM resulted in significant higher carbon dioxide partial pressure (CVD group: FFP2: 36.0 ± 3.2 mm Hg vs NM: 33.3 ± 4.4 mm Hg, p = 0.019; control group: FFP2: 32.6 ± 2.8 mm Hg vs NM: 28.1 ± 1.7 mm Hg, p <0.001) with corresponding differences in hydrogen carbonate and base excess, but not to a clinically critical extent. In conclusion, exercise testing with SM and FFP2 resulted in a significant reduction of peak power output without differences in hemodynamic parameters in subjects with preexisting CVD and in healthy subjects.
