Earlier this year, I experienced tightness (not pain) in my chest when walking uphill. The doc sent me for ECG and Stress Echo tests, both of which were OK. However, the Cardio doc says I have angina based on my diabetes, HBP, high cholestoral and family history. He has prescribed Ivabradine. I am reluctant to take yet more tablets, plus the feeling in my chest is less frequent. He left it up to me to decide what to do. Any advice?
