Abbreviations: CHD = coronary heart disease; HR = hazard ratio; MI = myocardial infarction; n = count per group; TNA = transient neurologic attack.

Model 1 adjusted for age at match date, study cohort (RS-I as reference), and maximal level of education (primary education as a reference). Model 2 in addition adjusted for obesity, smoking behavior (never smoking as reference), hypertension, diabetes mellitus, dyslipidemia, prevalent atrial fibrillation, and use of anti-thrombotic medication.
