[|AI|]  Hello! Thank you for asking on Chat Doctor! Regarding your question, I would explain that it is important performing some tests to investigate for the possible causes underlying your complaints: -a chest X-ray study-a resting ECG and a cardiac ultrasound-cardiac enzymes-complete blood count, PCR, ESR for inflammation. A cardiac stress echo would help investigate for coronary artery disease. A fibrogastroscopy may be needed to investigate for possible gastritis or gastroesophageal reflux, especially if your symptoms are relived by PPI (omeprazole, omeprazole, etc.). Hope you will find this answer helpful! Wishing all the best,
