My father had attach 7 months and 2 stent were placed in LAD and LCX. from then he is having some pain and when we met the cadiologist he said its muscle pain and asked him go to regular work. From past 20 days he is getting burning sensation in the heart and after he compeltes his morning walk and rests down for few mins and it goes off. Today when we met his doctor he told that angiogram should be done since there might be new blocks formed in the stent or other areas. Does heart burn relate to block in heart valves and should angiogram be performed. Is it a gastric problem.
