Changes in acute coronary syndrome in a decade in a provincial referral hospital.

Abstract Introduction and objective To determine the changes in the clinical and prognostic characteristics of patients admitted due to acute coronary syndrome (ACS) during the period between the years 2005 and 2015 in a provincial referral hospital. Material and method Cross-sectional observational study was conducted comparing the characteristics of ACS between 2005 and 2015. An analysis was made of the cardiovascular risk factors, treatment at discharge, complications, and mortality. Results The incidence of ACS in 2015 was 15.3% lower. The incidence of hypertension, diabetes and dyslipidaemia was similar, but there were more smokers in 2015 (25.9% vs 18.3%, P = .005). Coronary reperfusion and the prescription of secondary prevention treatments increased compared to 2005. Hospital mortality was similar. Conclusion The incidence of ACS has decreased in the last decade, in parallel with an improvement in the prognosis related to a more frequent use of the treatments recommended in the guidelines.
