If you have slight or developing Blood Pressure, Diabetes, and ongoing weight issues then a family Physician is not enough. You must also have a "Cardiologist" to check the effect of your other conditions on your heart and arteries. Rotate your appointments between your family physician and your Cardiologist, ongoing. If you have a good family physician, they will agree. If they don't agree then find another one!
Usually it is evident as soon as the cath is done to check the arteries that supply the heart muscle with blood. Chest pain would be the prime symptom.
