Outcome Measures
Go to 
Top of Page Study Description Study Design Groups and Cohorts Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. 2MACE score [ Time Frame: At baseline ]
    MACE: Major adverse cardiovascular events. 2MACE: History of Myocardial infarction/ Cardiac revascularization and Metabolic Syndrome, Age >75 years, Congestive heart failure (ejection fraction <40%), Thrombo-Embolism

  2. Occurrence of MACE to evaluate the performance of the 2MACE index [ Time Frame: At 2 years and 6 months or early termination ]
    Percentage of patients with MACE including fatal/nonfatal myocardial infarction, cardiac revascularization and cardiovascular death


Secondary Outcome Measures :
  1. Incorporation of additional risk factors to the 2MACE index or replacing some of the existing ones [ Time Frame: At baseline ]
    Risk factors to the 2MACE index (e.g. body mass index, smoking, drugs use, estimated glomerular filtration rate, structural cardio-pathology)

  2. Occurrence of major cardiovascular events (fatal/nonfatal myocardial infarction, cardiac revascularization and cardiovascular death) [ Time Frame: At baseline, at 1 year, at 2 years, at 2 years and 6 months or early termination ]
  3. Occurrence of stroke [ Time Frame: At baseline, at 1 year, at 2 years, at 2 years and 6 months or early termination ]
  4. Occurrence of transient ischemic attack (TIA) [ Time Frame: At baseline, at 1 year, at 2 years, at 2 years and 6 months or early termination ]
  5. Occurrence of systemic embolism [ Time Frame: At baseline, at 1 year, at 2 years, at 2 years and 6 months or early termination ]
  6. Thromboembolic risk based on the CHADS2 score [ Time Frame: At baseline ]
    CHADS2: Cardiac Failure, Hypertension, Age, Diabetes, Stroke

  7. Thromboembolic risk based on the CHA2DS2-VASC [ Time Frame: At baseline ]
    CHA2DS2-VASc:Cardiac failure, Hypertension, Age ≥75, Diabetes, Stroke -Vascular disease, Age and Sex category

  8. Number of MACEs occurring during the study [ Time Frame: At 1 year, at 2 years, at 2 years and 6 months or early termination ]
  9. Patients' profile [ Time Frame: At baseline ]
    Baseline patients' profile defined by: sociodemographic data, anthropometric data, previous relevant medical history, cardiac medical history distinct to atrial fibrillation, comorbidities (renal failure, left ventricular dysfunction, hypertension, thyroid dysfunction, liver failure, alcoholism)

  10. Number of cases (frequency) of metabolism syndrome at enrollment with/without the occurrence of myocardial infarction or coronary revascularization [ Time Frame: At baseline ]
