Reduction of No Reflow with a Loading Dose of Atorvastatin before Primary Angioplasty in Patients with Acute ST Myocardial Infarction.

BACKGROUND: No reflow defined as an altered myocardial reperfusion and failure at microvascular level is a frequent complication in acute myocardial infarction that attenuates beneficial effect of reperfusion therapy leading to poor outcomes. There is not enough evidence to support that previous use of statins improves coronary flow in patients undergoing primary percutaneous coronary intervention (PCI). AIM OF STUDY: To determine if a loading dose of 80 mg of atorvastatin before primary angioplasty reduces the frequency of no reflow, hs-CRP, IL6 intracoronary levels, and major combined cardiovascular events at 30 d. METHODS: In this controlled clinical trial, we randomly assigned 103 adult patients within the 12 h of acute ST-elevation myocardial infarction (STEMI) to receive 80 mg of atorvastatin additional to standard treatment (AST) before performing primary PCI versus standard treatment (ST) alone. The primary outcomes were the occurrence of no reflow and high sensitivity C-reactive protein (hs-CRP) and interleukin 6 levels and secondary outcomes were major adverse cardiovascular events at 30 d. RESULTS: 103 patients were analyzed, 49 (48%) received AST, 54 (52%) ST. Frequency of no reflow among groups was 27 vs. 63% respectively, p ≤0.0001. hs-CRP level was 2.69 mg/dL for AST vs. 2.2 mg/dL in ST, meanwhile IL-6 levels were 5.2 pg/mL vs. 6.35 pg/mL respectively, p = ns. Cox regression model demonstrated that the treatment assigned is an independent predictor for no reflow occurrence (HR 0.34 95%, CI 0.18-0.61, p ≤0.001). CONCLUSION: The administration of a loading dose of 80 mg atorvastatin before primary PCI is an effective strategy for prevention of no reflow improving also clinical outcomes and free survival rate for the presentation of major adverse cardiovascular events at 30 d.

Echocardiographic features of non-compaction cardiomyopathy: missed and misdiagnosed disease.

Non-compaction cardiomyopathy is a rare disease, anatomically characterized by a prominent trabecular pattern and deep intertrabecular recesses. Its clinical manifestations include severe left ventricular dysfunction, arrhythmias, systemic embolism, and sudden death. In this report, two cases of patients of different ages with non-compaction cardiomyopathy are described: a male schoolboy whose pathology was associated with mitral stenosis and regurgitation and a 50-year-old female with history of high blood pressure and cardiac failure.

A cardiomiopatia não-compactada é uma doença rara, anatomicamente caracterizada por um padrão trabecular proeminente e recessos intra-trabeculares profundos. Suas manifestações clínicas incluem disfunção ventricular grave arritmias, embolismo sistêmico e morte súbita. Nesse estudo, dois casos de pacientes de idades diferentes com cardiomiopatia não-compactada são descritos: uma criança do sexo masculino em idade escolar, cuja patologia estava associada com estenose mitral e regurgitação e um paciente adulto do sexo feminino, com 50 anos de idade e histórico de hipertensão arterial e insuficiência cardíaca.
