[Long-term survival after reconstructive surgery on non-coronary arteries in different age groups]

Abstract

The study was aimed at assessing long-term survival after reconstructive surgery on non-coronary arteries in different age groups as well as the confounding factors. 469 case histories were analyzed retrospectively. The most patients underwent coronary angiography (CA) and preventive myocardial revascularization along with non-coronary artery exam. The mean follow-up period was 57.5 +/- 14.9 months. The groups were similar in terms of aspirin and statin therapy; however, older patients more often received beta-blockers and ACE inhibitors (p < 0.03). The number of patients who undergone CA increased with age (p = 0.002). Older patients had higher long-term mortality (p = 0.008) and poorer long-term survival (p = 0.001) as compared to patients below 60 years of age. The risk of death increased with age (OR 1.11; p = 0.001), in smokers (OR 2.79; p = 0.009) and in case of complications in the postoperative period (OR 4.09; p = 0.001). In turn, lower mortality was associated with CA and further preventive myocardial revascularization, if medical reasons (OR 0.15; p = 0.001). Thus, routine CA and preventive myocardial revascularization were associated with lower long-term mortality. This allows recommending an aggressive preoperative assessment to this category of patients.
