(HealthDayNews) -- Although chest pain is often a warning signal of a heart attack, nearly half of all cardiac arrests begin without this classic symptom.
In a study by the University of California, San Francisco, 47 percent of heart attack victims showed other symptoms, including shortness of breath, dizziness, light-headedness, and in some cases, stomach pain, nausea and vomiting.
Cardiologists advise that if you go to the emergency room with breathing problems and you don't have a history of asthma, make sure the resident physician considers the possibility of a heart attack.
