I am seventy years old and frequently I have been experiencing Angina Pain, irregular heartbeat whilst pain exists. I seem to get relief from burping excessive gas. Please tell me if this is a symptom and what I should do about it. I do take Crestor for cholesterol and an 81 mg aspirin daily. I have had an angioplast but really didn't notice any difference.

Summarized question: What causes Angina Pain and irregular heart beat?
