Enlargement of one of the heart's four chambers — the right ventricle — was the only variable that was significantly associated with mortality in this group of Covid-19 patients, according to a new study
A team of doctors from the Icahn School of Medicine at Mount Sinai looked at the health records of 105 Covid patients hospitalized at Mount Sinai Morningside in New York City between March 26th and April 22nd. Of the 105 patients in the study, 32 of them -- or 31% -- had dilation of the right ventricle based on an echocardiogram, or ultrasound of the heart. Of these, 41% died by the end of the study period, compared to 11% of those without right ventricular enlargement.
Direct damage to heart tissue by the coronavirus may also be a contributing factor, they added. Coronavirus has previously been found to invade heart tissue because cardiac muscle cells are rich in ACE2 receptors -- a molecular doorway used by the coronavirus, according to the American Heart Association.
