RESUMEN
OBJECTIVES: To evaluate the systematic chain of care for patients with acute ST-elevation myocardial infarction (STEMI) referred for primary angioplasty in a capital city in Midwestern Brazil. BACKGROUND: Acute myocardial infarction is recognized as an important cause of morbidity and mortality and as a public health problem worldwide. Early specialized care is crucial for a good prognosis. METHODS: All STEMI patients receiving care through the public health system at two tertiary care centers from March 2012 to June 2014 were retrospectively analyzed. Symptom onset-to-balloon time and door-to-balloon time were analyzed and compared with current guideline recommendations. RESULTS: A total of 835 patients were included. Median symptom onset-to-balloon time was 32 h. A total of 783 (94%) patients had had symptoms for more than 12 h and 507 (61%) for more than 24 h. Only 51 (6%) patients arrived within 12 h of symptom onset and were treated with primary angioplasty. Among these patients, median door-to-balloon time was 37 min, in accordance with guideline recommendations. CONCLUSION: Treatment of STEMI through the public health system in a capital city in Midwestern Brazil falls short of the recommended guidelines due to failure in the initial links of the chain of care. This potentially reversible failure has an important impact on patient outcomes and on health care burden.
