Impact of COVID-19 on the Benefit of Cardiac Rehabilitation

Overview

The COVID-19 attack is polymorphic with otorhinolaryngological, pneumological, cardiac, digestive, neurological, muscular attacks with a higher mortality in subjects with comorbidity \[\> 70 years old, cardiovascular history in particular Arterial hypertension (hypertension ), heart disease…\]. This polymorphism is linked to vasculitis and the immune response. Patients with cardiovascular disease are particularly at risk of decompensating, particularly due to the increased metabolism induced by viral infection and reduced cardiovascular capacities. On the cardiovascular level, two sides can be considered. On the one hand, cardiovascular disease (hypertension, coronary artery disease) is a comorbid factor. On the other hand, the myocardial damage reflected by the increase in troponin or an alteration of the ejection fraction is a very clear risk factor for death or severe form. Cardiovascular involvement is particularly high in hospitalized and deceased patients. The odds ratio calculated in a meta-analysis of severe forms of covid-19 with hypertension is 3 \[1.9; 3.1\], for cardiovascular pathologies of 2.93 \[1.73; 4.96\]. Recommendations were made for pulmonary rehabilitation but not for cardiovascular rehabilitation. Cardiac rehabilitation is indicated in most cardiovascular pathologies (after acute coronary syndrome, after coronary angioplasty, in heart failure, after coronary or valve heart surgery, etc.). It consists of a multidisciplinary approach combining therapeutic pharmacological adjustment, physical activity, therapeutic education in order to improve physical capacities for exertion and reduce morbidity and mortality. The physical exercises can be endurance or resistance type. Capacity gain at the end of rehabilitation is measured by visual scales, quality of life questionnaires, and a stress test at the start and end of rehabilitation. Most often, rehabilitation centers only do the stress test and estimate through questioning for subjective improvement. The hypothesis is that patients who contracted COVID-19 would have lower cardiac capacities after recovery from the infection than patients without COVID-19 or that their capacity for recovery would be less. There could be a difference in recovery after cardiac rehabilitation between the two populations regardless of whether the cardiac damage requiring rehabilitation was triggered by COVID-19 or was pre-existing.
