There are times when we (as cardiologists) will send a patient for bypass surgery
of a single 100% blocked vessel, especially if it is the artery on the front of the heart (left anterior descending) and especially if heart muscle function is depressed (ejection fraction
). However, if heart muscle function is good and the body has made its own small bypass vessels (collateral arteries) we will often manage single vessel disease like you describe medically. It is then critically important that the other arteries stay healthy since part of the backup system is now gone. Medical management should include drugs that lower the risk of heart attack
progression. Aggressive treatment of cholesterol elevation
is critically important. You should also know that surgery is generally pursued to decrease the risk of death or to improve symptoms that can't be controlled medically, and your risk of death may not be high enough to justify the risk of surgery. Surgery does not generally reduce the risk of heart attack though (in the right circumstances) it can make heart attacks more survivable. Although i don't know enough about your condition to give you a definite personal answer, the situation you describe is not unusual. I will say, however, that treatment of your heart disease must include careful attention to minimizing your risk of plaque progression and plaque rupture
(i.e. Heart attack), which will likely involve aggressive therapy with statins
and/or other cholesterol lowering medications.
