After-Effects of Covid-19 on human body

After-effects of covid-19

The majority of those who contract the 2019 coronavirus disease (COVID-19) recover within a few weeks. But, some individuals — even those who had moderate forms of the disease — could experience symptoms for a very long period later. Some of the terms used to describe these persistent health issues are post-COVID-19 syndrome, post-COVID conditions, long-term COVID-19, and post-acute sequelae of SARS COV-2 infection (PASC).

How often is post-COVID-19 syndrome, and what is it?

Those who experience a range of new, recurring, or continuous symptoms more than four weeks after receiving COVID-19 are said to have post-COVID-19 syndrome. Post-COVID-19 syndrome can cause incapacity or last for months or years in certain persons.

A research team looked at the cardiac tissue of COVID-19 patients who had died from the illness, some of whom had had a history of heart issues. The researchers looked at autopsies and found several irregularities, especially in the way heart cells regulate calcium.

There were "abnormalities," according to Dr. Andrew Marks, head of Columbia University's physiology department ".

When it comes to their calcium systems, the cardiac tissue of these COVID-19 fatalities actually matched the heart tissue of individuals with heart failure. "We discovered signs of aberrant calcium handling in the hearts of COVID-19 patients, "added he.

"The information we provide indicates that the heart has undergone significant alterations, "Marks was cited by TIME as stating. To ascertain their precise origin and long-term effects, more research is needed.

All muscles, including those in the heart, require calcium to contract. Muscle cells accumulate calcium, which they subsequently release as needed by opening specialized channels. In some situations, such as heart failure, the channel may stay open to help the heart muscle contract more strongly. Over time, the calcium reserves are depleted by the calcium leak, weakening the muscle.

Marks wants to learn more about any potential heart alterations that SARS-CoV-2 might cause by looking at how the virus affects the hearts of mice and hamsters. He aims to evaluate changes in immune cells both during the infection and after the animals have recovered to look for any changes in heart function that may indicate any long-term effects.

According to past studies, there is a link between COVID-19 infections and heart-related problems. According to a thorough analysis of patients in the VA system from 2022, those with COVID-19 had increased rates of a variety of heart-related risks, including irregular heartbeats, heart attacks, and stroke. While some of these individuals achieved COVID-19 recovery, others had never received a diagnosis.
