A systematic evaluation of the available evidence suggests similarities as well as important differences in the risk factors for incidence of AF as compared with other cardiovascular diseases , which has implication s for the primary prevention strategies for atrial fibrillation
Established primary prevention strategies of cardiovascular diseases are based on underst and ing of risk factors , but whether the same risk factors are associated with  atrial fibrillation ( AF )  remains unclear .
Atrial fibrillation in the Malmö diet and cancer study: a study of occurrence, risk factors and diagnostic validity
The validity of atrial fibrillation ( AF ) diagnoses in national registers for use as endpoints in prospect i ve studies has not been evaluated . We studied the validity of AF diagnoses in Swedish national hospital discharge and cause of death registers and the occurrence of and risk factors for AF in a middle-aged Swedish population using these registers . Our study included the 30,447 individuals ( age 44–73 ) who attended baseline visits in 1991–1996 of the Malmö Diet and Cancer study . Individuals with a first AF diagnosis were identified by record linkage with national registers . A subset of cases was r and omly selected for validation by examination of electrocardiograms and patient records . Electrocardiograms were available in 98 % of the validation sample ( 95 % definitive AF , 3 % no AF ) . The 2 % with ECGs unavailable had probable AF . Baseline AF prevalence was 1.3 % , higher in men and increased with age . During 11.2 years of follow-up 1430 first AF diagnoses occurred . Risk factors were age , hypertension , BMI , diabetes , history of heart failure , history of myocardial infa rct ion and , in men but not women , current smoking . The strongest risk factors were history of heart failure ( hazard ratio men 4.5 , women 8.7 ) and myocardial infa rct ion ( hazard ratio men 2.0 , women 1.8 ) . The largest population attributable risks were observed for hypertension ( men 38 % , women 34 % ) and obesity ( men 11 % , women 10 % ) . In conclusion , case misclassification of AF in national registers is small , indicating feasibility of use in prospect i ve studies . Hypertension and obesity account for large portions of population risk in middle-aged individuals with low prevalence of manifest cardiac disease
