Have you recently been diagnosed with angina? Perhaps you have a family member or friend who’s living with angina and you’d just like to understand more about it and what it means to live with it. Is it the same thing as heart disease or a heart attack? What is angina anyway?
To better understand angina, you need to understand what it is -- and what it isn’t. Firstly, angina isn’t heart disease. Rather, it’s a symptom that serves as a red flag to more serious underlying heart conditions such as coronary artery disease, also known as CAD or heart disease, coronary microvascular disease, or MVD.
