"If it really is a few degrees warmer in the next 50 years, we could definitely have more cardiovascular disease," said Dr. Karin Schenck-Gustafsson, of the department of cardiology at Sweden’s Karolinska Institute. On the sidelines of the European Society of Cardiology’s annual meeting in Vienna this week, some experts said the issue deserves more attention. It’s well-known that people have more heart problems when it’s hot. … The hardening of the heart’s arteries is like rust developing on a car, said Dr. Gordon Tomaselli, chief of cardiology at Johns Hopkins University. "Rust develops much more quickly at warm temperatures and so does atherosclerosis," said Tomaselli, who is program chair at the American Heart Association. In higher temperatures, we sweat to get rid of heat. During that process, blood is sent to the skin where temperatures are cooler, which opens up the blood vessels. In turn, the heart rate rises and blood pressure drops. That combination can be dangerous for older people and those with weakened cardiovascular systems.
