ABSTRACT

OBJECTIVE: To evaluate compliance with American Heart Association/American College of Cardiology (AHA/ACC) performance measures for adults with acute myocardial infarction (AMI) and to investigate the factors associated with compliance, in an AMI System of Care in Brazil. DESIGN: Observational longitudinal study. SETTING: A high-complexity University Hospital, part of the AMI System of Care implemented in Belo Horizonte, Brazil, in 2010. PARTICIPANTS: Of note, 1129 patients with ST-elevation myocardial infarction (STEMI) and non-ST-elevation myocardial infarction (NSTEMI) admitted to a single center over 36 months (between 2011 and 2014). MAIN OUTCOME MEASURES: Compliance with 13 pre-specified AHA/ACC AMI performance measures was evaluated for patients with AMI, observing exclusion criteria and appropriate numerators and denominators. Median compliance was calculated and variables independently associated with compliance rates were evaluated. RESULTS: Median age was 60 (51/68) years, 67.7% male, 69.8% presented with STEMI and hospital mortality was 8.7%. Median compliance with performance measures was 83% (75/88). Among patients with STEMI, 56% received reperfusion therapy. Overall, 67.3% of patients complied with ≥80% of quality measures. Factors independently associated with better compliance were later date of presentation (semester), likely reflecting ongoing training (OR = 1.19, 95% CI: 1.10-1.28, P < 0.001), male gender (OR = 1.33, 95% CI: 1.00-1.76, P < 0.046), Killip I/II on admission (OR = 1.95, 95% CI: 1.36-2.80, P < 0.001) and diagnosis of NSTEMI (OR = 5.0, 95% CI: 3.51-7.11, P < 0.001). CONCLUSION: Compliance with AHA/ACC AMI performance measures remains below target in Brazil, but the time trends observed suggest improvement. Continuing education, reduction of system delays and prioritizing high-risk groups are needed to optimize AMI systems of care and improve patient outcomes.
