hI. I'm 30 years old. female. Had several episodes of Chest pains for the past 2 years. all began when I clim a hill and was breathless when arriving on top. My ECG was on SR C. I'm havin palpitations. I am on Betaloc 50 mg for the last 2 years. My symptoms are Chest pains which radiates to the left arm, feel dizziness and is always tired after small exertion.I am always on Low BP. My echo measureents are ; LVEDD 43 mm, LVESD 28 mm, LVEF 68%, IVS= 8m, PWT = 7mm, AOV 20 mm, LA = 26 mm. Summary was Good LV Systolic function, Normal valves and flow and LV WALL THICKNESS LOWER LIMIT NORMAL. I have ''Angised'' tablets under the tongue and the chest pains disapear as the tablet dissolve under my tongue. I was on ''Monicor tablets'' for 3 weeks. After the monicor, I had rarely chest pains. But I'm still on Betaloc.I went also for a Stress test which results for ST Depression and also for a CT Coronary Angiogram . Results was Normal Coronary Arteries. My question is what are the precautions I need to take to avoid any other chest pains and do I have a problem in my heart. Can ypu please clear my mind.
