TABLE 4.

The association between silent myocardial infarction and elevated coronary artery calcium score (log‐transformed) is provided using a multivariable linear regression model.

SMI	Participants (n)	CAC (median, IQR)	Model 1	Model 2	Model 3
			Unadjusted β (SE; p‐value)	Demographic‐adjusted β (SE; p‐value)	Adjusted β (SE; p‐value)
No SMI	6527	0 (0–81.5)	Reference	Reference	Reference
SMI	178	61.2 (0–261.7)	0.67 (0.10; p < .0001)	0.32 (0.08; p = .0001)	0.31 (0.08; p < .0001)

Note: Silent myocardial infarction is associated with a higher coronary artery calcium score in both unadjusted and adjusted models. Model 1 is unadjusted. Model 2 adjusts for age, sex, and race/ethnicity. Model 3 adjusts for the covariates in Model 2, plus smoking, diabetes, systolic blood pressure, antihypertensive medication use, statin use, high‐density lipoprotein cholesterol, total cholesterol, body mass index, left ventricular hypertrophy by electrocardiogram, and self‐reported physical activity.
