Cardiologist Questions Heart blockages

After having a bypass can I get blockages again?

I underwent a bypass 2 months ago and am still recovering. I have been feeling very anxious about going through this again. Can I get blockages again?

Unfortunately, it can happen. Make sure that you take baby aspirin daily, am exercise regularly, take statin to keep LDL under 70 to control blood sugar & bp. See your cardiologist at least once every 6 months. Keep your weight under control.
Bypass surgery is life improving in terms of improving symptoms and life prolonging by improving blood flow to the heart.
Bypass grafts do however accumulate plaque over time and can eventually fail. Arterial grafts remain patent for considerably longer than venous grafts. It’s imperative that patients continue to see their cardiologist after surgery to delay the recurrence of blockages and to prevent major adverse cardiovascular events in the future.
The blockages in your coronary arteries are still there, the surgery bypasses these blockages, so after surgery you can have worsening of the existing blockages, or you can form new blockages. This is why it is important to treat your risk factors-lower lipids, blood pressure and treat diabetes to lower your risk.
Bypasses only bypass the blockage. You have to change your life style and control your cardiovascular risk factors, so you prevent further disease, and actually can regress heart disease. You will also have to avoid 1st and 2nd hand smoking. Don't be anxious, just do the right thing.
Yes. Bypass is not a cure but a temporary improvement for coronary disease.
Lets first understand what got you to this point. You developed ATHEROSCLEROSIS in your arteries. There are reasons for that. We call then RISK FACTORS. Such as smoking, elevated cholesterol, high blood pressure, diabetes, obesity and sometimes a family history. So this "disease" has been present for a long time and will continue to be present UNLESS you make some significant changes in your life style, such as - a careful diet and a routine exercise - daily!
This is called risk modification. If you are very good at doing all of these things, including taking any prescribed medications, such as aspirin, you should do fine. We cannot say with 100% assurance that you will not have some disease recur, but if you do everything right, you will lower the risk the and limit the chances of recurrence.
