Background:

The outcomes of long-term follow-up constitute one of the best parameters to assess the quality of a medical intervention.

Objectives:

To analyze the overall and the free-of-cardiovascular events 20-year survival after coronary surgery in a community hospital with a long-standing electronic medical records.

Methods:

The results of coronary surgeries in patients with multi-vessel or trunk disease operated between 1999 and 2003 in a community hospital were retrospectively studied. The follow-up up to 20 years was carried out through the electronic medical record.

Results:

Of 272 patients operated, a mean follow-up of 125 months (range 6-268) was achieved in 254 (93.4%). The average number of bypasses was 3.3 (standard deviation 0.97); in 97.6%, at least one internal mammary artery was used and 59.4% received a radial artery graft. A follow-up of 2646 patient-years was obtained with an annual risk of death from all causes of 2.5%. The overall survival at the mean follow-up time was 0.806 (standard error (SE) 0.03), and the cardiovascular event-free survival 0.826 (SE 0.03).

Conclusions:

The complete electronic registration of affiliates to a community hospital operated more than 15 years ago allowed us to analyze the overall survival and the freedom of long-term events. These results will serve as a standard when choosing between surgery and multi-vessel angioplasty.
