Is heat bad for people with heart failure?

How does extreme heat affect the heart?

Radiation requires rerouting blood flow so more of it goes to the skin. This makes the heart beat faster and pump harder. On a hot day, it may circulate two to four times as much blood each minute as it does on a cool day.

How does heart failure affect temperature regulation?

The changes in the cardiovascular system that develop in chronic heart failure obviously affect thermoregulation. A constant, normal body temperature is the consequence of a regulated balance between heat production and heat loss. Both sides of this balance are altered in chronic heart failure.

How does heat exhaustion affect the heart?

Does weather Affect congestive heart failure?

Our study shows that exposure to cold or high-pressure weather could trigger events leading to hospitalization or death in heart failure patients.”
