A recent study highlighted that risk factors of heart disease like age, smoking, Diabetes increased risk of death in critically ill COVID-19 patients rather than any pre-existing heart disease. The findings are published in the journal Circulation: Cardiovascular Quality and Outcomes. Researchers looked at health outcomes of more than 5,100 patients admitted to intensive care units with severe COVID. Of those patients, 1,174 had either pre-existing coronary artery disease, congestive heart failure or atrial fibrillation..The study showed that people with heart disease were 30 per cent more likely to die than critically ill COVID patients without the pre-existing condition. However, when risk factors like age, sex, race, smoking were taken into consideration then that relationship was no longer statistically significant.The study showed that COVID-19 is a lung related disease which caused damage to multiple organs due to inflammation. The researchers also pointed out that people with heart disease are at risk of dying due to COVID-19, as they would also have a high number of risk factors for the disease.
