dear friend, Welcome to HCM.
very well asked question indeed.
 good that you asked.
 you have a problem here. 
hypertension, 48 age, significantly raised TG, low HDL, probably overcorrecting 
hypothyroidism and angina. a perfect recipie for a serious trouble.
 pl. urgently see a cardiologist. get worked up with ECG, 2D echo, / 
stress test if no angina, get dosage of 
thyronorm adjusted?lower. (needs a personal check up also). and lipid lowering therapy, appropriate anti-hypertensives, anti platelets.
 but after a consultation with a GIOOD cardiologist. and regular physician.
 takje adequate rest. anti anginals if sudden pain ( 
sorbitrate tablet below the tongue and pop an aspirin chewable )
good luck.
do not worry , but hurry checks.
pl. keep me posted.
