RESUMO

BACKGROUND: Previous evidence suggests that acute treatment with statins reduce atherosclerotic complications, including periprocedural myocardial infarction, but currently, there are no large, adequately powered studies to define the effects of early, high-dose statins in patients with acute coronary syndrome (ACS) and planned invasive management. OBJECTIVES: The main goal of Statins Evaluation in Coronary procedUres and REvascularization (SECURE-PCI) Trial is to determine whether the early use of a loading dose of 80 mg of atorvastatin before an intended percutaneous coronary intervention followed by an additional dose of 80 mg 24 hours after the procedure will be able to reduce the rates of major cardiovascular events at 30 days in patients with an ACS. DESIGN: The SECURE-PCI study is a pragmatic, multicenter, double-blind, placebo-controlled randomized trial planned to enroll around 4,200 patients in 58 different sites in Brazil. The primary outcome is the rate of major cardiovascular events at 30 days defined as a composite of all-cause mortality, nonfatal acute myocardial infarction, nonfatal stroke, and coronary revascularization. SUMMARY: The SECURE PCI is a large randomized trial testing a strategy of early, high-dose statin in patients with ACS and will provide important information about the acute treatment of this patient population.

RESUMO

Importance: The effects of loading doses of statins on clinical outcomes in patients with acute coronary syndrome (ACS) and planned invasive management remain uncertain. Objective: To determine if periprocedural loading doses of atorvastatin decrease 30-day major adverse cardiovascular events (MACE) in patients with ACS and planned invasive management. Design, Setting, and Participants: Multicenter, double-blind, placebo-controlled, randomized clinical trial conducted at 53 sites in Brazil among 4191 patients with ACS evaluated with coronary angiography to proceed with a percutaneous coronary intervention (PCI) if anatomically feasible. Enrollment occurred between April 18, 2012, and October 6, 2017. Final follow-up for 30-day outcomes was on November 6, 2017. Interventions: Patients were randomized to receive 2 loading doses of 80 mg of atorvastatin (n = 2087) or matching placebo (n = 2104) before and 24 hours after a planned PCI. All patients received 40 mg of atorvastatin for 30 days starting 24 hours after the second dose of study medication. Main Outcomes and Measures: The primary outcome was MACE, defined as a composite of all-cause mortality, myocardial infarction, stroke, and unplanned coronary revascularization through 30 days. Results: Among the 4191 patients (mean age, 61.8 [SD, 11.5] years; 1085 women [25.9%]) enrolled, 4163 (99.3%) completed 30-day follow-up. A total of 2710 (64.7%) underwent PCI, 333 (8%) underwent coronary artery bypass graft surgery, and 1144 (27.3%) had exclusively medical management. At 30 days, 130 patients in the atorvastatin group (6.2%) and 149 in the placebo group (7.1%) had a MACE (absolute difference, 0.85% [95% CI, -0.70% to 2.41%]; hazard ratio, 0.88; 95% CI, 0.69-1.11; P = .27). No cases of hepatic failure were reported; 3 cases of rhabdomyolysis were reported in the placebo group (0.1%) and 0 in the atorvastatin group. Conclusions and Relevance: Among patients with ACS and planned invasive management with PCI, periprocedural loading doses of atorvastatin did not reduce the rate of MACE at 30 days. These findings do not support the routine use of loading doses of atorvastatin among unselected patients with ACS and intended invasive management.

RESUMO

INTRODUCTION: The apical ballooning syndrome (ABS) is a single reversible cardiomyopathy often triggered by a stressful event. We aimed to present a case report regarding this disorder. CASE PRESENTATION: Here we present the case of a 77-year-old female hypertensive patient, sedentary and non-smoker, diagnosed with apical ballooning syndrome. We describe the clinical signs and symptoms, changes in markers of myocardial necrosis and changes in the electrocardiogram and coronary angiography. CONCLUSION: The course of events patient showed clinical improvement with treatment and support was not necessary to administer specific medications or interventions to reverse the situation. After hemodynamic stabilization coronary angiography showed no obstructive lesions and left ventricle with akinesia of the apex and the middle portion of the left ventricle.
