RESUMEN
BACKGROUND: Influenza vaccination prevents major cardiovascular events in individuals presenting a recent acute coronary syndrome (ACS), however the early effect of an in-hospital double-dose vaccination strategy remains uncertain. METHODS: The VIP-ACS was a randomized, pragmatic, multicenter, open-label trial with a blinded-adjudication endpoint. Patients with ACS ≤ 7 days of hospitalization were randomized to an in-hospital double-dose quadrivalent inactivated influenza vaccine (double-dose) or a standard-dose influenza vaccine at 30 days post-randomization. The primary endpoint was a hierarchical composite of death, myocardial infarction, stroke, hospitalization for unstable angina, hospitalization for heart failure, urgent coronary revascularization, and hospitalization for respiratory infections, analyzed with the win ratio (WR) method in short-term follow-up (45-days after randomization). RESULTS: The trial enrolled 1,801 patients (≥18 years old). Median participant age was 57 years, 70 % were male. There were no significant differences between groups on the primary hierarchical endpoint: there were 5.7 % wins in the double-dose in-hospital group and 5.5 % wins in the standard-dose delayed vaccination group (WR: 1.03; 95 % CI: 0.70---1.53; P = 0.85). In a sensitivity analysis including COVID-19 infection in the hospitalizations for respiratory infections endpoint, overall results were maintained (WR: 1.03; 95 % CI 0.71---1.51; P = 0.87). Results were consistent for major cardiovascular events only (WR: 0.82; 95 % CI: 0.48---1.39; P = 0.46). No serious adverse events were observed. CONCLUSION: In patients with recent ACS, in-hospital double-dose influenza vaccination did not significantly reduce cardiorespiratory events at 45 days compared with standard-dose vaccination at 30 days post-randomization.

Importance: Loading doses of atorvastatin did not show reduction on clinical outcomes in the overall population of patients with acute coronary syndrome (ACS) enrolled in the Statins Evaluation in Coronary Procedures and Revascularization (SECURE-PCI) trial, but a potential benefit was identified in patients who subsequently underwent percutaneous coronary intervention (PCI). Objectives: To determine whether periprocedural loading doses of atorvastatin are associated with decreased 30-day major adverse cardiovascular events (MACE) in patients with ACS undergoing PCI according to type of ACS and timing of atorvastatin administration before PCI. Design, Setting, and Participants: Secondary analysis of a multicenter, double-blind, placebo-controlled, randomized clinical trial conducted at 53 sites that enrolled 4191 patients with ACS intended to be treated with PCI between April 18, 2012, and October 06, 2017. Interventions: Patients were randomized to 2 loading doses of 80 mg of atorvastatin or matching placebo before and 24 hours after a planned PCI. By protocol, all patients (regardless of treatment group) 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 through 30 days, composed by all-cause mortality, myocardial infarction, stroke, and unplanned coronary revascularization. Cox regression models adjusting for key baseline characteristics were used to assess the association between atorvastatin and MACE in patients undergoing PCI. Results: From the overall trial population, 2710 (64.7%) underwent PCI (650 women [24.0%]; mean [SD] age, 62 [11.3] years). Loading atorvastatin was associated with reduced MACE at 30 days by 28% in the PCI group (adjusted hazard ratio [HR], 0.72; 95% CI 0.54-0.97; P = .03). Loading dose of atorvastatin was administered less than 12 hours before PCI in 2548 patients (95.3%) (45.1% < 2 hours and 54.3% between 2 and 12 hours). There was no significant interaction between treatment effect and timing of study drug administration. The treatment effect of loading atorvastatin was more pronounced in patients with ST-segment elevation myocardial infarction than in patients with non-ST-segment elevation ACS (adjusted HR, 0.59; 95% CI, 0.38-0.92; P = .02; HR, 0.85; 95% CI, 0.58-1.27; P = .43, respectively). Conclusions and Relevance: In patients with ACS undergoing PCI, periprocedural loading doses of atorvastatin appeared to reduce the rate of MACE at 30 days, most clearly in patients with ST-segment elevation myocardial infarction. This beneficial effect seemed to be preserved and consistent, irrespective of the timing of atorvastatin administration, including within 2 hours before PCI.

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.

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.
