What Is The Success Rate Of Coronary Bypass Surgery?

Success Rate of Coronary Bypass Surgery

Believe it or not, bypass surgery is done often enough to be considered the most common type of heart surgery. It is complex, and it involves many risks. But what we’re going to be talking about today is not the risks. Instead, our subject choice is on the success rate of coronary bypass surgery. For that, the quick answer is…

Nowadays, the success rate of coronary bypass surgery is at an all-time high. Specifically, around 95% of those who are operated on do not experience any life-threatening complications. And, only 1-2 percent are at risk of dying as a result of getting the operation performed.

Those are the odds discovered by a 5-year study that compared the advantages of coronary stenting to the advantages of bypass surgery. However, it’s not the full story. So, continue reading if you want to learn more.

Is Coronary Bypass Surgery Safe?

Bypass surgery is performed when one or more of a patient’s blood vessels become partially blocked. Specifically, blood vessels that transport blood to the heart muscles. The procedure requires a significant amount of preparation and quite a long recovery period.

However, as far as the consideration of other alternatives, coronary bypass surgery just so happens to be one of the safest and most effective methods available.

Not only that, but it also greatly reduces the risk of a heart attack or stroke in patients who suffer from various vascular disease, heart diseases, and more.

According to the Washington Post, whilst the operation cannot be considered completely safe, it has improved in success rate over the decades, although the same cannot be said when it comes to life expectancy.

Life Expectancy After Bypass Surgery

Bypass surgery can add more years to your life, but this all depends on your age, level of fitness, and general health.

It will ease your ailing and decrease the risk of heart attacks and death, but as of right now, studies show that only 74% of patients operated on survive for more than ten years.

Now, it should be said, that this isn’t necessarily a representation of what is going to happen to certain patients. The percentage, whilst accurate, is a bit skewed as most of those that get operated on are already in their later years.


So, what can we conclude?

We know that the success rate of coronary bypass surgery is fairly high. It’s also considered one of the safest ways of removing blockages in a person’s blood vessels. Finally, we know that, while the life-expectancy after bypass surgery is probably lower than what we’d all like to hear, it does work.

There is life after the procedure. It just requires some recovery and a bit of restraint.

If a patient learns to take care of themselves and try out the available preventative measures? Then, they should be able to experience a happier and healthier life that can last for years or even decades.
