question: my dad is 58 years old. he has been a diabetic for 15 years now. for the past few months he has been experiencing chest discomfort which sets in during night. ECG taken on all those occasions were normal and administration of medicines could alleviate the discomfort. his triglyceride levels have been high for the past few years and he has been consistently on statins and fibrates. apart from that there were episodes of hypoglycemia for which the diabetologist reduced the dosage of the medicine and he has been on semi-doanil for the past 2 months. however, when he had similar kind of suffering yesterday in the night 1 hour after having dinner, the RBS levels showed up as 272mg/dl. occasionally whenever he experiences this kind of a problem he is also used to taking tancodep that seems to relax him and gives him good sleep. are all these symptoms of angina?
