Key result
Waist circumference did not improve the discriminatory performance of the GRACE risk score (AUC 0.60) for predicting six-month mortality or myocardial reinfarction (9.5% overall event rate).
Why the study?
Does the addition of waist circumference to the GRACE risk score improve prognostic value for six-month mortality or myocardial reinfarction in patients with acute coronary syndrome?
Population
285 patients admitted consecutively to a cardiac care unit with acute coronary syndrome
Comparison
Addition of waist circumference to the GRACE… vs GRACE risk score alone

Does not support adding waist circumference to GRACE for ACS prognosis; leaves open whether alternative adiposity metrics enhance discrimination in larger cohorts.

No
Does the addition of waist circumference to the GRACE risk score improve prognostic value for six-month mortality or myocardial reinfarction in patients with acute coronary syndrome?
Measuring waist circumference does not add prognostic value to the GRACE risk score for predicting six-month mortality or reinfarction in patients with acute coronary syndrome.
Martins et al. (2013) conducted a cohort in Acute coronary syndrome (n=285). Waist circumference (abdominal obesity) vs. GRACE risk score alone was evaluated on Composite of all-cause mortality or myocardial reinfarction within six months. Waist circumference did not improve the discriminatory performance of the GRACE risk score (AUC 0.60) for predicting six-month mortality or myocardial reinfarction (9.5% overall event rate).
