I am experiencing symptoms like heart attack i.e., chest tightness, profuse sweating, chest pain, nausea etc. That's why my angiography was done a month ago. It showed that coronary arteries are absolutely clear with 0% obstruction. But there is an evidence of Coronary Slow Flow in the angiography. My doctor has prescribed Ecosprin 75mg OD. Additionally he told me that my symptoms might be because of Microvascular and Endothelial Dysfunction. So my question is can this condition cause heart attack? If yes, then how much serious and severe attack may occur? Is it severe enough to cause death? What is the treatment of this condition???
