<s>[INST] 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. [/INST] HiWhile this could be a gastric acid reflux problem it has to be considered cardiac until proved otherwise so you need immediate evaluation with an EKG, echocardiogram, and a stress test </s>
