78% of recovered COVID-19 patients show heart problems, say German doctors

Among the cohort, 33 patients required hospitalisation while others recovered at home.

Even after COVID-19 patients beat the virus and recover, they may have lasting effects on their heart health, reveals a new study.

More than three-quarters of recently-recovered COVID-19 patients had heart muscle problems show up during cardiac magnetic resonance (CMR) imaging tests, German doctors have stated in JAMA Cardiology study. CMR looks at the structural changes in the heart.

In the study, published on July 27, the researchers observed a cohort of 100 German patients who had recently recovered from the novel coronavirus infection. Of these, 53 percent were men and the rest were women, and the median age was 49 (45-53) years.

As per the findings, 78 percent of patients who had recovered showed some signs of cardiac effects while in 60 percent of patients, there were signs of ongoing myocardial (heart muscle) inflammation.

“In this study of a cohort of German patients recently recovered from COVID-19 infection, CMR revealed cardiac involvement in 78 percent patients and ongoing myocardial inflammation in 60 percent, independent of pre-existing conditions, severity and overall course of the acute illness, and time from the original diagnosis,” the researchers said.

Frequently Asked Questions

How does a vaccine work?

A vaccine works by mimicking a natural infection. A vaccine not only induces immune response to protect people from any future COVID-19 infection, but also helps quickly build herd immunity to put an end to the pandemic. Herd immunity occurs when a sufficient percentage of a population becomes immune to a disease, making the spread of disease from person to person unlikely. The good news is that SARS-CoV-2 virus has been fairly stable, which increases the viability of a vaccine.

How many types of vaccines are there?

There are broadly four types of vaccine — one, a vaccine based on the whole virus (this could be either inactivated, or an attenuated [weakened] virus vaccine); two, a non-replicating viral vector vaccine that uses a benign virus as vector that carries the antigen of SARS-CoV; three, nucleic-acid vaccines that have genetic material like DNA and RNA of antigens like spike protein given to a person, helping human cells decode genetic material and produce the vaccine; and four, protein subunit vaccine wherein the recombinant proteins of SARS-COV-2 along with an adjuvant (booster) is given as a vaccine.

What does it take to develop a vaccine of this kind?

Vaccine development is a long, complex process. Unlike drugs that are given to people with a diseased, vaccines are given to healthy people and also vulnerable sections such as children, pregnant women and the elderly. So rigorous tests are compulsory. History says that the fastest time it took to develop a vaccine is five years, but it usually takes double or sometimes triple that time.

They further said that, as per their knowledge, this was the first prospective report on a cohort of unselected patients with a recent COVID-19 infection identified from a local testing center who voluntarily underwent evaluation for cardiac involvement with CMR.

Among the cohort, 33 patients required hospitalisation while others recovered at home. The home recoveries were either asymptomatic or had mild symptoms. There was no difference in the incidence of cardiac changes in the two groups.

“Our findings demonstrate that participants with a relative paucity of preexisting cardiovascular condition and with mostly home-based recovery had frequent cardiac inflammatory involvement, which was similar to the hospitalized subgroup with regards to severity and extent, the researchers stated in the report.

The results of the study provide important insights into the prevalence of cardiovascular involvement in the early convalescent stage, they mentioned.

These findings indicate the need for the ongoing investigation of the long-term cardiovascular consequences of COVID-19, suggested the group of German doctors.
