A new study conducted by Israeli doctors at the Ichilov Hospital in Tel Aviv has found that some 40% of patients hospitalized with the Coronavirus (COVID-19) subsequently experienced the weakening of the right ventricular, shedding new light on the pandemic’s comprehensive effects.
When the pandemic began to spread at the end of 2019, reports emerged from China about myocardial defects caused by the disease.
Dr. Yishay Szekely, a senior cardiologist, initiated a cardiac echo and lung sonar examination for hospitalized patients suffering from various degrees of the virus, with the objective of identifying primary cardiac damage and providing a basis for comparison in the event of deterioration during hospitalization.
The study, based on the results of tests monitoring 100 hospitalized patients, discovered that about 40% of patients suffered from right ventricular dysfunction in varying degrees of severity, becoming the most common cardiac defect caused in Corona patients.
In a minority of patients, the left ventricular function was impaired.
The main conclusion reached by doctors was that a right ventricular injury was the hallmark of Corona’s cardiac injury.
Professor Yan Topilsky, Deputy Director of the Cardiovascular System at Ichilov, explained that “the cardiac damage is probably the result of a pulmonary injury – the right ventricle of the heart ‘sees’ high pulmonary tension and its function is impaired as a result.”
This is the first in the world to systematically describe a cardiac injury to Corona patients using cardiac imaging, rather than laboratory tests alone.
“Performing the tests in patients in serious condition and in patients whose condition deteriorated throughout the hospitalization contributed to understanding the reasons for the deterioration and directing the care of these patients,” the study said.
As for heart function after recovery from the acute illness, patients who have recovered will need to be monitored.
