Patient comorbidities, such as diabetes mellitus (P = .015), CAD (P = .008), and AF (P = .002), as well as laboratory abnormalities, such as higher serum creatinine levels (P = .008) and lower eGFR (mL/min/1.73 m2; P < .001) were more frequent in the hs‐cTnT elevated group. This evidence concerns the gene TNNT2 and atrial fibrillation.
