Incidence of myocardial infarction and vascular death in elderly patients with atrial fibrillation taking anticoagulants: relation to atherosclerotic risk factors.
BACKGROUND Recent findings suggest that patients with atrial fibrillation ( AF ) , in addition being at thromboembolic risk , are at risk of myocardial infa rct ion ( MI ) . Our aim was to investigate predictors of MI and cardiovascular death in a cohort of patients with AF who were taking anticoagulants .  METHODS We prospect ively followed up 1,019 patients with AF for a median of 33.7 months ( 3,223 person-years ) . All patients were treated with oral vitamin K antagonists . Primary outcome was a composite end point of cardiovascular events ( CVEs ) including fatal/nonfatal MI , cardiac revascularization , and cardiovascular death . RESULTS The mean age of the patients was 73.2 years , and 43.8 % were women . At follow-up , 111 CVEs ( 3.43%/y ) had occurred : 47 fatal-nonfatal MI/revascularization and 64 cardiovascular deaths . In addition , 31 stroke/transient ischemic attacks ( 0.96%/y ) were recorded . Patients experiencing CVEs were older ( P < .001 ) and had a higher prevalence of metabolic syndrome ( MetS ) ( P = .005 ) , heart failure ( P = .001 ) , and prior cardiac ( P < .001 ) and cerebrovascular events ( P < .001 ) . On a Cox proportional hazard analysis , age ( hazard ratio [ HR ] , 1.083 ; 95 % CI , 1.053 - 1.113 ; P < .001 ) , smoking ( HR , 2.158 ; 95 % CI , 1.193 - 3.901 ; P = .011 ) , history of cerebrovascular ( HR , 1.704 ; 95 % CI , 1.119 - 2.597 ; P = .013 ) and cardiac ( HR , 1.658 ; 95 % CI , 1.105 - 2.489 ; P = .015 ) events , MetS ( HR , 1.663 ; 95 % CI , 1.107 - 2.499 ; P = .014 ) , heart failure ( HR , 1.584 ; 95 % CI , 1.021 - 2.456 ; P = .040 ) , and male sex ( HR , 1.499 ; 95 % CI , 1.010 - 2.223 ; P = .044 ) predicted CVEs . CONCLUSIONS Patients with AF still experience a high rate of CVEs despite receiving anticoagulant treatment . MetS is a common clinical feature in patients with AF , which increases the risk of CVEs . A holistic approach is needed to reduce the cardiovascular risk in patients with AF .
