If angina comes from blocked arteries, does that mean everyone with angina should have angioplasty or bypass surgery to open them up?
Not necessarily. Only in people with certain “high-risk” characteristics (e.g. unstable symptoms, triple vessel disease, poor heart muscle function) has it been proven that we can prolong life by these methods. Many other people do fine for many years or even decades, just by taking aspirin, cholesterol-lowering medication, etc. Invasive procedures are not always necessary.
