Scientists have calculated the risks of cardiovascular disease after Covid-19

(ORDO NEWS) — As it turned out, even generally healthy people who have been ill in a mild form can face such serious consequences of a coronavirus disease.

A study by scientists at the Washington University School of Medicine in St. Louis and staff from the St. Louis Health System for Veterans Affairs in the United States found that people who had Covid-19, even a mild form, were at an increased risk of developing Covid-19 for one month to a year after infection.

Diseases of the cardiovascular system and dangerous conditions: cerebrovascular diseases, arrhythmia, ischemic and non-ischemic heart disease, pericarditis, myocarditis, heart failure and thromboembolism.

The authors of the article analyzed databases of the US Department of Veterans Affairs and obtained a sample of 153,760 people who survived Covid-19 from March 2020 to January 2021: few of them were vaccinated, since vaccination in the United States did not begin until the end of 2020 of the year.

Also, the currently dominant strains of the virus were not taken into account.- “delta” and “omicron”. Participants were mostly older white males, although there were women and people of other ages and races.

Two control groups were recruited: 5,637,647 US Veterans Health users and another 5,859,411 people for whom information was collected before the pandemic. The aim was to assess the risk of cardiovascular events within 12 months for both the general cohort and for those treated for coronavirus disease in hospitals, intensive care units or at home.

As a comparative analysis showed, people who survived Covid-19 after a month had a 1.52 times increased risk of stroke, 1.49 times increased risk of transient ischemic attack , 1.71 times increased risk of atrial fibrillation (atrial fibrillation), 1. 84 times – sinus tachycardia and ventricular arrhythmias, 1.53 times – sinus bradycardia, 1.80 times – atrial flutter, 1.85 times – pericarditis , 5.38 times – myocarditis, 1.72 times – acute coronary disease, 1.63 times – myocardial infarction, 1.52 times – angina pectoris, 1.72 times – heart failure, 2.45 times – cardiac arrest, 2.43 times – cardiogenic shock , 2, 93 times – pulmonary embolism, 2.09 times – deep vein thrombosis, 1.95 times – superficial vein thrombosis.

On average, the probability of developing cerebrovascular diseases was increased by 1.53 times (burden – 5.48 per 10 thousand people after 12 months), arrhythmias – by 1.69 times (burden – 19.86), inflammatory diseases of the tissue membrane of the heart (pericardium ) – by 2.02 times (1.23), coronary heart disease – by 1.66 times (7.28), other cardiovascular diseases – by 1.72 times (12.72), thromboembolic disorders – by 2 .39 times (9.88).

The researchers then assessed the risks and burdens of two endpoints: the so-called major adverse cardiovascular condition (combination of myocardial infarction, stroke, and all-cause mortality) and any cardiovascular outcome, that is, the development of any of the above diseases.

Compared with the first control group, whose data were collected during the pandemic, Covid-19 survivors were 1.55 times more likely to experience a major adverse cardiovascular event (burden 23.58) and 1.63 times more likely to experience any cardiovascular event. – vascular outcome (burden – 45.29).

After adjusting for age, race, sex, obesity, hypertension, diabetes, chronic kidney disease, hyperlipidemia, cardiovascular disease, and bad habits (smoking), the risk remained elevated for all subgroups of people who recovered from Covid-19.

“The increased risk and associated burden was also evident among those who were not hospitalized during the acute phase of the disease, which includes the majority of people who have had a coronavirus infection.

In addition, the risk and associated burden showed a gradual increase across the spectrum of severity of the acute phase of Covid-19 (from non-hospitalized to hospitalized patients to those admitted to intensive care),” the scientists specified.

They stressed that the best way to prevent the lingering coronavirus disease and its myriad complications is to avoid the infection itself.

Plus, given the increase in the incidence of Covid-19 and the proportion of people who have been ill – and this is more than 400 million people in the world – many people may subsequently face serious consequences of the coronavirus.
