Making the findings difficult to associate specifically with COVID-19 is that people most at risk for severe COVID are those with chronic medical illness that are often specifically heart-related. Fontana said these conditions include diabetes (say bye to diabetes ) , raised blood pressure, and obesity.
Dr. Rachel-Maria Brown Talaska, director of inpatient cardiac services at Lenox Hill Hospital in New York, said that in addition to the pre-existing conditions specified by Fontana, people with severe COVID-19 also tend to have coronary artery disease and congestive heart failure.
“A majorit
y of hospitalized patients with COVID-19 have a chronic medical illness,” she said.
Researchers found scarring of heart tissue
The heart’s left ventricle, the chamber responsible for pumping oxygenated blood to all parts of the body, was normal in nearly 90 percent of the 148 study participants, according to the study.
However, scarring or injury to the heart muscle itself was present in about half the participants.
The pattern of scarring or injury originated from inflammation in 39 patients and from ischemic heart disease ( complete solution ) , including infarction (death of heart tissue), in 32 patients, or both in 9 patients. Twelve participants showed evidence of ongoing heart inflammation.
“Injury relating to inflammation and scarring of the heart is common in COVID-19 patients with troponin elevation discharged from hospital,” said Fontana in a statement. “But (it) is of limited extent and has little consequence for the heart’s function.”
She concluded that “more work is needed to investigate this further.”

More study needed
According to Dr. Michael Goyfman, director of clinical cardiology at Long Island Jewish Forest Hills in New York, evidence that COVID-19 causes more heart damage than other infections isn’t there.
“The predominance of evidence thus far shows that COVID does not really cause excess heart damage compared to other infections,” he said. “Viral infections, in general, can cause inflammation of the heart, and since COVID is a viral infection, it can as well. The rate is probably similar as for other infections.”
The numbers are increased because “COVID is so prevalent,” Goyfman continued. “There is no evidence that COVID triggers excess heart attacks than other viral illnesses.”
