hi. I am a 40 year old male with normal weight and BMI , fairly active lifestyle and do not have any other health conditions. occasional drinker. don t smoke . i have had an episode of chest pain 2 days ago (on lest side ,not behind sternum bone, without associated arm heaviness.) this happened at night when i was preparing to sleep. i drove to the ER and my ecg was done which came out normal. however my BP was high (150/100) i was given one antacid medication and restyl tablet for anxiety. i soon felt better and came home. next day again in the afternoon i had similar symptoms and again my bp was high (150/100) i took rest whole day and again checked my bp and it came normal. i do not have any anxiety issues. and i don t lead a hectic lifestyle. next day morning, i was returning home from chores and despite a/c being on in the car, i did sweat more than usual, enough to soak my shirt in the back. at this time i had no chest pain, in fact i was feeling better than the last two days, but my bp again came out high .i got a few blood tests done ( lipid and sugar) and been to a cardiologist . they did a 2d echo and ecg and both were normal. troponin levels were also normal. now I m advised to undergo angiography. i really don t understand what s happening. why is my bp shooting up and is there any other way to detect the cause than to have to undergo invasive angiography? looking forward to your opinion. thank you.
