Clinical management and hospital outcomes of acute coronary syndrome patients in Mexico: The Third National Registry of Acute Coronary Syndromes (RENASICA III)
Abstract Objective To describe current management and clinical outcomes in patients hospitalized with an acute coronary syndrome (ACS) in Mexico. Methods RENASICA III was a prospective multicenter registry of consecutive patients hospitalized with an ACS. Patients had objective evidence of ischemic heart disease; those with type II infarction or secondary ischemic were excluded. Study design conformed to current quality recommendations. Results A total of 123 investigators at 29 tertiary and 44 community hospitals enrolled 8296 patients with an ACS (4038 with non-ST-elevation myocardial infarction/unstable angina [NSTEMI/UA], 4258 with ST-elevation myocardial infarction [STEMI]). The majority were younger (62 ± 12 years) and 76.0% were male. On admission 80.5% had ischemic chest pain lasting >20 min and clinical stability. Left ventricular dysfunction was more frequent in NSTEMI/UA than in those with STEMI (30.0% vs. 10.7%, p < 0.0001). In STEMI 37.6% received thrombolysis and 15.0% primary PCI. PCI was performed in 39.6% of NSTEMI/UA (early strategy in 10.8%, urgent strategy in 3.0%). Overall hospital death rate was 6.4% (8.7% in STEMI vs. 3.9% in NSTEMI/UA, p < 0.001). The strongest independent predictors of hospital mortality were cardiogenic shock (odds ratio 22.4, 95% confidence interval 18.3-27.3) and ventricular fibrillation (odds ratio 12.5, 95% confidence interval 9.3-16.7). Conclusion The results from RENASICA III establish the urgent need to develop large-scale regional programs to improve adherence to guideline recommendations in ACS, including rates of pharmacological thrombolysis and increasing the ratio of PCI to thrombolysis.
