A COVID-19 death can occur when underlying conditions contribute to the disease.
Diabetes is a frequent contributing factor often in concert with heart disease. The third-most noted conditions were lung problems.
Among the heart conditions most often seen is hypertension, or high blood pressure.
"There’s a real risk for people who have high blood pressure as one of the factors that we see contributing to a higher severity of disease," said Dr. Aileen Marty of Florida International University.
Medications for hypertension, including ACE inhibitors, could make cells more welcoming to the virus, but Marty said there is no evidence yet to substantiate that.
"From what we see now, it's better to keep people on their ACE inhibitors and maintain their pressures as correctly as possible," she said.
