Study Finds Cold Limbs and Breathlessness Signal Heart Attack Risk

A new study reveals that heart attack symptoms extend beyond chest pain to include cold hands and feet and breathlessness with lung crackles. These signs, especially cold limbs, indicate a higher risk of death during hospitalization for STEMI heart attack patients. Reduced blood flow due to the heart's inability to pump adequately may cause these symptoms, highlighting the need for urgent medical attention.
