Cardiologists warn of increased heart risks during heatwaves

cardiovascular health heatwave risks heart attack symptoms dehydration heatstroke

Medical experts are warning of increased cardiovascular risks associated with high temperatures and specific physical symptoms. Dr. Massimo Volpe, president of Siprec, noted at the European Congress of Cardiology that heat causes vasodilation and increased heart rates, placing significant stress on the heart, particularly in elderly or predisposed individuals.

Clinicians emphasize that sudden chest pain—especially when it radiates to the back, shoulders, or jaw and is accompanied by shortness of breath, cold sweats, or nausea—must be treated as a potential medical emergency. While not all back pain indicates a heart attack, sudden and unusual sensations require immediate professional evaluation.

To mitigate risks during heatwaves, experts recommend maintaining electrolyte balance through proper hydration and consuming foods rich in water, fiber, and antioxidants, such as leafy greens, watermelon, and fatty fish. Conversely, excessive sodium intake from foods like cured meats and the diuretic effects of alcohol can exacerbate dehydration and blood pressure fluctuations.
