MSTN and diabetes mellitus: In univariate analysis, diabetes (OR 11.82, 95% CI −3.49–43.03; p = 0.095), smoking (OR 11.34, 95% CI 0.78–45.40; p = 0.043), left ventricular ejection fraction <40% (OR 19.53, 95% CI 10.88–87.76; p = 0.012), GRACE risk score (OR 0.16, 95% CI 0.16–0.76; p = 0.003), and time to admission (OR 0.01, 95% CI −0.02–0.001; p = 0.065) and log GDF8 (OR 21.59, 95% CI 34.08–119.05; p <0.001) were associated with the prediction of troponin Ic peak.
