Impact of creating a haemodynamics room, a coronary unit and a primary angioplasty programme on the prognosis of acute coronary syndrome in a district hospital.

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. 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). 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). 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.
