RESUMO
We report the case of a young woman referred to our hospital for anterior ST-elevation myocardial infarction to be treated with primary coronary angioplasty. Angiography showed total dissection of the left anterior descending coronary artery, which was successfully treated with primary coronary angioplasty and multiple coronary stent implantation. Spontaneous coronary artery dissection is an unusual cause of acute coronary syndrome, which occurs more frequently in women with many pregnancies (our patient had eight sons before hospital admission for acute myocardial infarction). Although technically challenging, primary coronary angioplasty is a good strategy for treating coronary artery dissection.

BACKGROUND: The most important limitation in primary percutaneous coronary interventions (PCI) for acute myocardial infarction (AMI) is the small number of catheterization laboratories and their non-homogeneous territorial distribution. The aim of this study was to evaluate the safety and efficacy of an organizational model based on a network including tertiary referral centers and community hospitals for the treatment of AMI with alteplase plus abciximab followed by PCI. METHODS: From October to November 2002, 232 patients < or = 75 years with AMI at high risk (84 transferred from four community hospitals and 148 patients admitted directly at the tertiary center) underwent PCI at our Institution. We compared procedural results and clinical outcome in patients with AMI undergoing PCI with or without transfer to tertiary centers. RESULTS: Patient transferal from community hospitals determines a greater door-to-balloon time (120 vs 55 min, p < 0.001), while complications observed during transportation are limited (5.9%). Transferred patients have a greater percentage of infarct-related artery patency (77 vs 22%, p < 0.001) and of ST-segment resolution 90 min post-PCI (77 vs 57%, p < 0.005) in comparison with direct-access patients. The incidence of clinical events (death, reinfarction, angina) was not different between the two groups at 30 days and at 6 months of follow-up. CONCLUSIONS: In our experience the integrated model between tertiary centers and community hospitals represents a valid network system offering homogeneous therapeutic (alternatives) options to all patients with AMI regardless of the hospital where they are first admitted.
