A recent research financed by the National Institutes of Health projects a considerable rise in heart-related mortality in the United States as a result of excessive heat.

The heat index increased to at least 90 degrees on around 54 days every summer, according to a study that was published on Monday in the journal Circulation. The study examined the data from May to September of 2008–2019. The high temperatures on those days were associated with 1,651 cardiovascular deaths annually on average across the country.

Researchers predict that if greenhouse gas emissions continue to climb, there might be up to 80 days in the United States between 2036 and 2065 with those extremely high temperatures. Their predictions are based on changes in the environment and population. Cardiovascular deaths might triple to 5,491 year as a result.
