People who have had CVIV-19 have a 55% increased risk of developing cardiovascular disorder in the year following the infection. This is what follows the follow-up of a vast American cohort, Posted in the magazine Nature Medicine of 7 February. The disorders observed were of any type of abnormal heart rate (arrhythmias), occurring blood clots (thromboses) and pulmonary embolism, stroke (stroke), coronary heart disease, heart failure and myocardial infarction, and even death by one These causes, but also inflammation of the heart or its envelope (myocarditis and pericarditis).
In total, the study included 153,760 people positive for the SARS-COV-2 virus between the 1 er March 2020 and 15 January 2021 and having survived the first thirty days of disease. Very few had been vaccinated before infection – the vaccines being available at the end of this period.
Infected persons have been compared to a first group of more than 5.6 million people not infected over the same period; and another control group of more than 5.8 million patients followed before the pandemic, between March 2018 and January 2019. The study did not affect the delta and Omicron variants, appeared after the period of follow-up.
“A little cold in the back”
All medical records analyzed, rendered anonymous, came from the “cohort of veterans”, managed by the US Department of Veterans and followed at the Washington University of Saint-Louis. This cohort included a majority of men (89%) white (71%), an average of 61.4 years.
Results: between the second and the twelfth month after the infection, the risk of doing an acute infarction was increased by 72%. Either at absolute risk, 5 to 6 additional cases for 1,000 infected persons. The risk of heart failure was increased by 72% (12 more cases). Just as the risk of developing “atherosclerosis”, resulting from an accumulation of grease plates and proteins inside the arterial wall, slowing the flow of blood that irrigates the heart (11 more cases). The risk of “atrial fibrillation”, a heart rhythm disorder that exposes the risk of stroke and heart failure, increased by 71% (11 more cases); The risk of pulmonary embolism, 193% (5 more cases) and the risk of stroke of 52% (4 cases plus).
“It’s a robust study, says Professor Xavier Jouven, Head of the Cardiovascular Pole of the Georges-Pompidou European Hospital (AP-HP, Paris). The increase in risk concerns all cardiovascular events, What is a little cold in the back. “
