Cardiologists in North Carolina warn cold weather raises heart attack risks

Cardiologists in North Carolina are warning that cold weather increases the risk of heart attacks, especially for those with existing health issues. Cold temperatures constrict blood vessels, adding stress to the heart. Respiratory viruses common in winter months also contribute to this risk. Hospitals are seeing more patients, leading to visitor restrictions at Duke Health and UNC Health systems. Doctors emphasize the importance of recognizing heart attack symptoms, particularly in women, who may not show typical signs. They recommend routine check-ups, a healthy lifestyle, and CPR training to improve survival chances.
