Top in cardiology: Serious health effects of ‘heat dome,’ air pollution

A “heat dome” like the one that descended over the Northeast and Midwest United States may increase cardiovascular risk, especially in vulnerable populations, according to Jonathan Newman, MD, MPH.
Newman, a cardiologist at the NYU Langone’s Center for the Prevention of Cardiovascular Disease, said older and younger people, as well as pregnant women, are at especially high risk during periods of intense heat. Further, patients using medication such as diuretics and ACE inhibitors to manage preexisting heart conditions such as heart failure and CVD may have increased cardiovascular risk under the heat dome.
“During the heat dome periods, avoid strenuous outdoor activity during the really hot hours of the day, if you can,” Newman told Healio. “Stay in an air-conditioned environment if you have access to one. Visit a cooling center in urban environments in New York and New Jersey, including libraries.”
The interview with Newman was the top story in cardiology last week.
In another top story, air pollution may contribute to increased cardiovascular and cancer risk by causing systematic inflammation and oxidative stress, according to data from a state-of-the-art review.
