Analysis reveals heart-related side effects of hydroxychloroquine and chloroquine | EurekAlert! Science News
"Hydroxychloroquine [HCQ] and chloroquine were associated with higher rates of various cardiovascular problems, including life threatening heart rhythm events, heart failure, and damage to the heart muscle itself (termed cardiomyopathy)."
"Moreover, we show how these adverse events carry high risks for severe outcomes including death, even with standard doses of the drugs."
My comment: The reason I easily found this link is because I looked, as opposed to Sean Hannity who I recently heard on the radio still promoting Hydroxychloroquine.
