Fundamento: A estratificação do risco de morte dos pacientes no contexto da angioplastia primária (ATC) é fundamental. Objetivo: Identificar os fatores relacionados ao desfecho morte em pacientes submetidos a ATC. Métodos: Estudo de caso-controle, utilizando como fonte de dados um registro brasileiro. A associação entre cada variável e o desfecho óbito foi avaliada via modelo de regressão logística binária. Consideramos significativo p<0,05. Resultados: Foram analisados 26.990 registros, sendo 18.834 (69,8%) do sexo masculino, com idade mediana de 61 (17) anos. Na análise multivariada, as principais variáveis relacionadas ao desfecho óbito com seus respectivos odds ratio e intervalos de confiança (IC) com nível de significância de 95% foram a idade avançada 70 -79 anos (2,46; 1,64 -3,79) e

“…Within this context, the use of adjunctive tools to effectively prepare the lesions has been the most effective and safe means to achieve success, and sustained long-term results in interventions in calcified arteries. 2 The revival of RA in the era of drug-eluting stents (DES), particularly in very complex calcified lesions, underscores the importance of plaque modifications before the DES can be successfully introduced, precisely positioned, and deployed to exert the desired effects. The RA acts according to the principle of "differential cutting" and "orthogonal displacement of friction", by selectively eliminating the inelastic fibrocalcified plaques and sparing the adjacent elastic tissue.…”

Background: The treatment of coronary arteries with heavily calcified or chronically occluded lesions has the lowest success rates when they undergo a percutaneous procedure. A strategy to reduce the volume of calcified lesions, which was part of the rescue technique to treat non-balloon dilatable stenoses, has evolved to an approach of primary lesion preparation for subsequent stenting. Methods: This is a retrospective analysis of data related to rotational atherectomies performed in complex, high-risk patients, for treating extremely calcified lesions with drug-eluting stent implantation, obtained from the Tasy Electronic Medical Record, between 2012 and 2016. Results: A cohort of 138 individuals was followed up after rotational atherectomy between 2012 and 2016. The most frequently observed risk factors were hypertension (87%), dyslipidemia (69%), diabetes mellitus (44%), and sedentary lifestyle (72%). A total of 244 vessels were treated, 179 of which with the aid of rotational atherectomy, and 308 drug-eluting stents were implanted. The SYNTAX II score was 22.4±11.5, with 18% of individuals classified as high risk (>33 points); femoral arterial access was employed in 76.8%. Lesion transposition was achieved in 98% of cases. Angiographic success was achieved with stenting in 98% of procedures. The length of hospital stay was 2.6±3.7 days. In-hospital mortality was 4%, and 4-year mortality was 14.5%. Long-term follow-up was performed by phone calls up to 4 years after the procedure. Ninety-seven percent of patients maintained regular use of dual antiplatelet therapy. Only 42% reported regular exercise. Angina pectoris was reported by 13% of individuals. Conclusion: Rotational atherectomy showed a low occurrence of adverse events in the immediate and late phases, leading to a high success rate of stent implantation in complex lesions.
