The Impact of Medical Face Masks and Rehabilitation Duration on the Performance Output and Outcomes of Cardiologic Rehabilitants.

During the COVID-19 pandemic, wearing a medical face mask became mandatory in daily life and also in cardiological rehabilitation. In order to investigate whether the performance and outcomes of cardiological rehabilitation were affected by face masks, we compared data from patients who underwent rehabilitation with face masks with data from patients without face masks. In total, 114 patients from an ambulant rehabilitation center were included.
