Resumo

HAMEAU, René et al. Excess non cardiac mortality in patients undergoing PCI of venous coronary bypass grafts. Rev Chil Cardiol [online]. 2018, vol.37, n.3, pp.176-182. ISSN 0718-8560.  http://dx.doi.org/10.4067/S0718-85602018000300176.

Background

Failure rates of saphenous vein grafts can reach almost 50% at 10 years and percutaneous angioplasty is the treatment of choice. This is a group with a very high cardiovascular risk, with mid-term mortality rates close to 30%.

Aim

To describe the population undergoing coronary bypass angioplasty (CBA) and compare their mortality with an age and gender matched group of patients with acute myocardial infarction with ST segment elevation (STEMI)

Methods

This was a retrospective case-control study including patients with CBA between 2010-2016. This group was compared with the same number of controls with STEMI matched by age and sex. Clinical characteristics, procedure variables and overall mortality as well as cardiac mortality were analyzed using Student's T test, Chi squared test and Kaplan Meier curves (significance set at p <0.05). Results: We identified 63 patients undergoing CBA (76 procedures). The most commonly intervened bypasses were to the circumflex artery (48.7%). There were 18 (28.5%) patients who died in the CBA group and 6 (9.5%) patients in the STEMI group, which resulted in an excess of global mortality risk in patients with CBA (HR 3.02, 95% CI 1.11 - 8.22, p = 0.02).

This difference was driven by a higher non-cardiac mortality in the CBA group (12.7% (n = 8) vs 3.2% (n = 2) [p = 0.04])

Conclusion

Patients undergoing CBA have a mortality rate more than three times that of the STEMI patients, mainly due to a higher non-cardiac mortality.
