A recent stem cell study has shown that SARS-CoV-2, the novel coronavirus, can infect heart cells via the same receptor present in the lungs. This may be responsible for the cardiac complications associated with COVID-19. Experts initially thought that COVID-19 was a respiratory disease, with symptoms including cough, shortness of breath, and pneumonia. However, more recent evidence into COVID-19 shows that the disease can also cause neurological and cardiac symptoms. Physicians have reported changes to the circulatory system in people with COVID-19, sometimes leading to blood clots, as well as cardiac complications, such as changes to the heart rhythm, damage to heart tissue, and heart attacks. Although there is widespread agreement that COVID-19 is a risk to the heart, whether these symptoms are due to the virus directly or a consequence of other disease processes, such as inflammation, has been unclear.
