RESUMEN
OBJECTIVE: To analyse the prognosis and mortality of patients hospitalised for acute coronary syndrome before and after the implementation of a coronary unit, haemodynamics room and the Código corazón primary angioplasty programme. METHODS: We conducted an observational and retrospective study that analysed the epidemiological characteristics, reperfusion strategies, adverse cardiovascular events and mortality for 5 years of follow-up. The results of the post-code period (March 1 - December 31, 2012; n=471) were compared with those of the pre-code stage (March 1 - December 31, 2009; n=432). RESULTS: There were no differences in the baseline characteristics of the 2 groups; however, an increase in ST-segment elevation acute coronary syndrome (STE-ACS) from 17.6% to 34.8% (P<.001) was observed during the post-code phase. The use of percutaneous coronary intervention was made widespread at the hospital, achieving rates of 64.8% in non-ST-segment elevation acute coronary syndrome (NSTE-ACS) and of 95.5% in STE-ACS. Readmissions were reduced (from 38.2% to 25.1% for NSTE-ACS [P=.001] and from 23.7% to 11.0% for STE-ACS [P=.018]), the combined prognostic variable of adverse cardiovascular events and mortality at 5 years of follow-up was reduced (from 58.7% to 45% [P=.001] for NSTE-ACS and from 40.8% to 23.8% [p=.009] for STE-ACS), and 30-day mortality was decreased for STE-ACS (from 11.8% to 3.7%; P=.021). CONCLUSIONS: With the structural changes in the hospital, the use of percutaneous coronary intervention was made widespread and improved the prognosis of patients with acute coronary syndrome, decreasing admissions, adverse cardiovascular events and mortality.
RESUMEN
OBJECTIVE: This work aims to analyze the prognosis and mortality of patients hospitalized for acute coronary syndrome before and after the implementation of a coronary care unit, hemodynamics room, and the Código Corazón [Infarction Code] primary angioplasty program. METHODS: We conducted an observational, retrospective study that analyzed the epidemiological characteristics, reperfusion strategies, adverse cardiovascular events, and mortality over a follow-up period of five years. The results from the post-code period (March 1 - December 31, 2012; n=471) were compared with those from the pre-code period (March 1 - December 31, 2009; n=432). RESULTS: There were no differences in the baseline characteristics of the two groups. However, an increase in ST-elevation acute coronary syndrome (STE-ACS) from 17.6% to 34.8% (p<.001) was observed during the postcode phase. The use of percutaneous coronary intervention was made widespread at the hospital and was used in 64.8% of non-ST-elevation acute coronary syndrome (NSTE-ACS) cases and in 95.5% of STE-ACS cases. A reduction was observed in readmissions (from 38.2% to 25.1% for NSTE-ACS (p=.001) and from 23.7% to 11.0% for STE-ACS (p=.018)), the composite prognostic variable of adverse cardiovascular events and 5-year mortality (from 58.7% to 45% (p=.001) for NSTE-ACS and from 40.8% to 23.8% (p=.009) for STE-ACS), and a decrease in 30-day mortality in STE-ACS (from 11.8% to 3.7%; p=.021). CONCLUSIONS: With the structural changes in the hospital, the use of percutaneous coronary intervention was made widespread and improved the prognosis of patients with acute coronary syndrome, decreasing admissions, adverse cardiovascular events, and mortality.
