Always feel i am having heart attacksob, chest/arm pain. had lots of ecgs always fine. how will i know when it is a heart attack have high cholesterol?

See a cardiologist: The determination of the cause of your chest pain cannot be made by EKG alone. Studies show that the EKG is only 25-50% sensitive in the detection of myocardial infarction. If a physician has high suspicion of myocardial infarction, Troponin-I enzymes must be performed. A stress test or nuclear medicine study can be employed. Optimize your diet, cardiovascular risks and exercise with physician.
