People who have been fully vaccinated against COVID-19 have a significantly lower risk of developing more severe cardiovascular conditions linked to COVID-19 infection, according to a nationwide study at the University of Gothenburg. At the same time, some cardiovascular effects are seen after individual doses of the vaccine. The COVID-19 vaccine aims to reduce complications and overall mortality from the disease.
A rare acute side effect is inflammation of the cardiac muscle or the pericardium in young men following mRNA vaccination. In terms of other cardiovascular effects , there has only been limited research and the results have been conflicting. Published in the European Heart Journal , a register-based, nationwide study is based on data from the entire population of more than eight million adults in Sweden who were followed up in national health care registers for around two years, from the end of December 2020, when COVID-19 vaccination began, until the end of 2022.
The researchers have studied 'risk windows' (the time immediately after a single injection of the COVID vaccine ), dose by dose, in those who were vaccinated. The cardiovascular health after full vaccination has then been compared with the cardiovascular health of those who, at the same stage of the study, had not started any vaccination. Risk analyses for cardiovascular disease The study includes risk analyses for a number of cardiovascular diseases related to both the heart and the brain: inflammation of.
