When entering hypertension, atherosclerotic disease, atrial fibrillation, current smoking, bowel emptying, WBC, CRP, ASAT, and D-dimer in a multivariable logistic regression model, only elevated D-dimer (OR 9.32 per one standard deviation increment, 95% CI 1.31–66.39; p = 0.026) remained as an independent factor associated with arterial occlusive AMI. The gene discussed is CRP; the disease is atrial fibrillation.
