SARS-CoV-2, the virus that causes COVID-19, can damage the heart even without directly infecting the heart tissue, a study has found. The research, published in the journal Circulation, specifically looked at damage to the hearts of people with SARS-CoV-2-associated acute respiratory distress syndrome (ARDS), a serious lung condition that can be fatal. But researchers said the findings could have relevance to organs beyond the heart and also to viruses other than SARS-CoV-2.

Scientists have long known that COVID-19 increases the risk of heart attack, stroke, and Long COVID, and prior imaging research has shown that over 50% of people who get COVID-19 experience some inflammation or damage to the heart...

In fruit flies, antioxidants reverse tumor-related cardiac dysfunction. A new study in animal models shows that the presence of a cancer tumor alone can lead to cardiac damage, and suggests the culprits are molecules are free radicals interacting with specific cells in the heart.

Tumors in mice and fruit flies led to varying degrees of cardiac dysfunction – particularly a decrease in the heart’s blood-pumping capabilities.

Adding specific types of antioxidants to food consumed by fruit flies with tumors reversed the damage to their hearts – a finding suggesting that harm caused by free radicals was the likely link between cancer and cardiac dysfunction.
