    Death from any cause.
  • Myocardial injury after noncardiac surgery (MINS) [ Time Frame: 30 days ]

Pathological confirmation of myocardial necrosis on necropsy will also be accepted
  • Cardiovascular death [ Time Frame: 30 days ]

    Mortality attributed to progression of cardiovascular diseases or sudden death in an otherwise healthy subject
  • Elevation of markers of myocardial necrosis [ Time Frame: 72hs ]
    Estimation of lesion to myocytes by: value of troponin T at 24hs, area under the curve (AUC) of troponin T over the first 72hs after surgery, peak value of troponin T during hospital stay
  • Stroke [ Time Frame: 30 days ]
    New neurologic symptom with compatible lesion on brain imaging and confirmation by a neurologist of the diagnosis of stroke
  • Ultrasensitive PCR [ Time Frame: 72hs ]
    Substitute outcome for inflammation after surgery
  • Liver enzymes [ Time Frame: 30 days ]
    Elevation of AST and ALT after randomization
  • CPK [ Time Frame: 30 days ]
    Elevation of CPK after randomization, as a substitute for rhabdomyolysis
  • Myalgia [ Time Frame: 30 days ]
    Myalgya as a substitute for rhabdomyolysis
  • Creatinine [ Time Frame: 30 days ]
    Substitute for renal dysfunction
  • Arrhythmia [ Time Frame: 30 days ]
    New atrial fibrillation, new atrial flutter, new tachycardia requiring chemical or electrical cardioversion, new need for temporary or definitive pacemaker
  • PE/DVT [ Time Frame: 30 days ]
    New pulmonary embolism or deep vein thrombosis diagnosed by the caring physician
  • Infection [ Time Frame: 30 days ]
    New infection requiring antibiotics, as diagnosed by the caring physician
  • MI [ Time Frame: 30 days ]
    Rate of myocardial infarction as defined by any 2 of: typical chest pain OR typical ECG changes (ST-segment depression, ST-segment elevation, new Q waves, transitory T wave inversion) OR new rise in troponin levels (CK-MB levels if unavailable) OR new wall motion abnormality on echocardiogram. Pathological confirmation of myocardial necrosis on necropsy will also be accepted

Lowering the Risk of Operative Complications Using Atorvastatin Loading Dose
Multicenter Randomized Controlled Trial of Loading Dose Statins for the Prevention of Cardiovascular Complications in High-Risk Non-Cardiac Surgery
Patients submitted to noncardiac surgeries are at increased risk of serious cardiovascular complications. Statins have shown to lower cholesterol levels and reduce cardiovascular events in other scenarios. The objective of this study is to explore the effects of atorvastatin, as compared with placebo, on the 30-day risk of a composite of death, nonfatal Myocardial Injury after Noncardiac Surgery (MINS), or stroke among patients who undergo noncardiac surgery.

Cardiovascular complications, such as myocardial infarction (MI) and stroke are common in the perioperative period of noncardiac surgeries. To the moment there are no safe and effective interventions to reduce vascular events in this scenario. Data from observational studies and small-sized randomized controlled trials (RCTs) have shown promising results in terms of risk reduction. In addition, experimental data have indicated that statins have acute anti-inflammatory properties, which promote the stabilization of atherosclerotic lesions and, therefore, might reduce the risk of MI, even in the short term. This study was designed to explore the effects of atorvastatin, as compared with placebo, on the 30-day risk of a composite of death, nonfatal Myocardial Injury after Noncardiac Surgery (MINS), or stroke among patients who undergo noncardiac surgery.

The study was conducted in accordance with the prespecified protocol and reached successful enrollment rates when, by the end of 2014 the steering committee was invited to join an international initiative and participate in a much larger clinical trial to investigate this relevant question. Due to this outstanding possibility, the steering committee decided to redesign the study which is now formatted as an exploratory trial. As described, the study was completed with the inclusion of 648 participants in June, 2015.
