Can I have Concor 5mg and then do TMT.

Dear Doctors, I am 42 years old unmarried man. I am 107kg in weight and 5 feet 6 inch tall. I take medicine for GERD Nexpro L and Nexpro 20mg, for Asthma Montek AB and Formoflo inhaler, Asthalin 200mg rotohaler, High BP, High heart beat on walking upto 175bpm, and Cetrizen for urticaria. Taking Inzofresh 10mg for sleep. I have severe ED for the past 8 months. I am having Concor 5mg from October 19, given by cardiologist. I have done Echocardiogram in July 19 by a Cardiologist. Report is fine. I have done Endoscopy in January 19 by a Gastroenterologist report is fine. My HDL is low at 35, master health check up done in December 19. Am I having heart blockage? Why ED problem? I don't do any excercise or walking. I want to do Angio but frightened to do it.  I tried doing TMT in a hospital but on walking for 1 minute My heart beat went up to 125. The staff stopped TMT. Cardiac Specialist did not allow me to do TMT then. Can I do TMT after having Concor 5mg? Fear Angio!
