Heart attacks occur when blood flow to the heart is blocked. If the blocked artery isn’t reopening quickly, the part of the heart that is prevented from receiving blood begins to die. Even if you aren’t sure if you are having a heart attack, call 9-1-1. Our Paramedics can begin treatment as soon as they arrive, which is about an hour faster (on average) than you would receive treatment if you were to drive yourself to the emergency room. Symptoms of a heart attack vary and can include shortness of breath, nausea/vomiting in both men and women. Men can also experience cold sweats. Women can experience back or jaw pain.
