These results showed that AF is an independent risk factor for MI , CV death , and CV events
This study aim ed to investigate whether  atrial fibrillation ( AF ) predicts myocardial infa rct ion ( MI ) or cardiovascular ( CV ) death .
AF is a well-established risk factor for thrombotic stroke and all-cause mortality .
Risk of Myocardial Infarction or Vascular Death After First Ischemic Stroke: The Northern Manhattan Study
Background and Purpose — In national guidelines , absolute long-term risk of myocardial infa rct ion ( MI ) or coronary death determines target low-density lipoprotein levels , but stroke patients are not explicitly addressed . We determined the absolute 5-year risk of cardiovascular outcomes and their predictors after first ischemic stroke in a multiethnic cohort . Methods — A population -based cohort of first ischemic stroke patients ≥40 years old was prospect ively followed annually for recurrent stroke , MI and cause-specific mortality . Kaplan-Meier 5-year risks for MI or vascular death ( primary outcome ) , and other cardiovascular events , were calculated . Univariate and multivariate Cox proportional hazards models were used to calculate hazard ratios and 95 % CI for predictors of cardiovascular outcomes . Results — Mean age ( n=655 ) was 69.7±12.7 years ; 55.4 % of participants were women , and 51.3 % Hispanic .  The 5-year risk of MI or vascular death was 17.4 % ( 95 % CI , 14.2 % to 20.6 % ) . Independent historical predictors of MI or vascular death were age > 70 years ( hazard ratio 1.62 , 1.07 to 2.44 ) , history of coronary artery disease ( hazard ratio 1.76 , 1.13 to 2.74 ) , and atrial fibrillation ( hazard ratio 1.76 , 1.05 to 2.94 ) . In the lowest risk group , those ≤70 years old without coronary artery disease , 5-year risk of MI or vascular death was 9.7 % . Conclusions — The absolute risk of MI or vascular death after ischemic stroke , even in those without high-risk features , approximates levels used by national organizations to design ate groups of patients at high risk of vascular events . The comparability of levels of absolute risk among stroke and cardiac patients may have treatment implication
