Elderly patients are usually under-represented in randomized controlled trials, therefore there is less data providing prognostic information for this particular group. NSTEMI clinical practice guidelines indicate that older patients should receive the same therapeutic strategy than younger patients. Methods Observational retrospective study including 8771 patients admitted for acute coronary syndrome in two tertiary referral hospitals between 2003 and 2017: 5673 NSTEMI (64.3%) and 3098 STEMI (35.7%). 999 patients presenting with NSTEMI and aged over 75 years were selected and divided into 3 groups: aged 75–80, aged 80–89 and aged over 90. Cox proportional hazard regression analysis was performed in order to determine independent predictors of mortality. Mortality and survival were represented by Kaplan-Meier curves and log rank test was conducted to assess significant differences in survival between groups. Median follow-up period was 48 months. Results A significant association between female sex and elder age was observed, also a higher prevalence of hyperlipemia and diabetes. In acute phase, no significant differences were found in between congestive heart failure onset, myocardial re-infarction, acute renal failure, stroke or in-hospital mortality amongst the 3 groups. However, at follow-up period, higher mortality in elder groups was documented. After performing a multivariate analysis, age was identified as an independent predictor of mortality at follow-up ( 〈 90 years: HR 1.50 CI 95% 1.23–1.83, p=0.0001, 〉 90 years: HR 1.93 CI 95% 1.27–2.93, p=0.002) as well as GRACE score (HR 1.06, CI 95% 1.02–1.09, p=0.002), CRUSADE score (HR 1.01 CI 95% 1.01–1.02, p=0.0001) and treatment with digoxine (HR 1.38 CI 95% 0.95–2.0, p=0.08). On the other side, beta-blockers (HR 0.71 CI 95% 0.59–0.86, p=0.0001) and complete coronary revascularization (HR 0.48 CI 95% 0.37–0.64, p=0.0001) were found to be protective factors. Conclusions In very elderly patients presenting with NSTEMI, prognostic predictors of mild-term mortality are similar to those present in younger patients. Recommendations of clinical practice guidelines, such as beta-blockers' treatment and coronary revascularization, should also be applied in elderly patients.
