27 Year Survival After CABG
A 2012 NIH study showed a significant advantage for Coronary Artery Bypass Grafting (CABG) surgery compared with non-surgical procedures.
Older adults with stable CAD who underwent bypass surgery had better long-term survival rates than those who underwent PCI. While there were no survival differences between the two groups after one year, after four years the CABG group had a 21% lower mortality rate.
I have reviewed the issue of long term survival extensively in comparison with other studies that include the SYNTAX trial. However, none have adressed survival beyond 5 years.
With an annual mortality rate (if not treated) for patients with stable coronary artery disease of about 2% and 10-20%/year in patient populations similar to patients operated by me, 25+ year survivals must be remarkable.
This is what I learned this past week:
A secretary from one of the State’s cardiology offices called and asked about one of my patients. To my delight I learned this regarded a patient operated in 1988. When asked she said he was doing fine, but had just called to make a routine office appointment.
I called back later for more details, but couldn’t remember the name. However, since I have maintained my patients data till 2001 when I retired, I looked up that year, and mentioned some of the names on my list; of the first ten, five were active patients in their practice!
The following image shows my patient’s long-term survival up to 200 months after their surgery (data collected from 1983-2001, 93% of female and 86% of male patients alive 16 years later after their bypass surgery):
Long Term Survival:
Patient Characteristics show these patients were high risk and had a very low morbidity/mortality:
Although this is incidental information, I now know that at least five patients are alive 27 years after their bypass surgery. A comparison with available literature shows that most investigations limit their reviews to less then 10 years after an intervention such as a stent or bypass surgery. Of significance, there are very few survival studies out there!
You are so right about the lack of long term studies. Most studies of cabg patients cover a few weeks to a few months post-op..
I have 7 bypssses( 7jump CABG).March 1990.I was 49 years old at that time. AAA surgery Oct 2021. Real great!
I have a stent for 17years . Should I get it checked to see if it has determined or needs replacement? I stopped taking the 3statins after 3years, but with regular health checks from my md
I had a cabg 10 years ago, and just had 3stents in Coronary artery is this usual, and how long will I hold up?
Had three stents inserted left and right arteries August 2005 at the age of 64.
I take 75mg aspirin 10 mg statins and 5 mg ramapril.
I have regularly trained for over 40 years weight lifting, jogging and biking.
I still feel good.
Will my stents last much longer ?
