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 .
Chronic atrial fibrillation--epidemiologic features and 14 year follow-up: a case control study.
In a r and omly selected population of 9067 individuals , 32 - 64 years of age in 1967 - 1970 , 25 ( 0.28 % ) had chronic atrial fibrillation ( CAF ) . Eight had lone atrial fibrillation .  In 1984 the cases were compared with an age- and sex-matched control group of 50 and found to have more cerebrovascular accidents ( 6 versus 2 ; P less than 0.05 ) , congestive heart failure ( 9 versus 1 ; P less than 0.001 ) , and valvular rheumatic heart disease ( 3 versus 0 ) or history consistent with rheumatic fever ( 6 versus 0 ; P less than 0.01 ) . The mortality in the CAF group was 60 % higher due to an excess in cardiovascular ( relative risk 6.1 ; P less than 0.05 ) and cerebrovascular ( relative risk 12.2 ; P less than 0.05 ) causes . The prevalence or incidence of ischaemic or hypertensive heart disease or the presence of coronary risk factors did not significantly differ in the two groups . By M-mode echocardiography the left atrial size , left ventricular enddiastolic dimension and left ventricular mass were increased in the CAF patients , while the systolic left ventricular shortening was significantly less . Thus , the prevalence of CAF is low in a r and omly selected population 32 - 64 years of age and CAF is not strongly associated with ischaemic heart disease or hypertension . The CAF patients have an increased risk of dying prematurely particularly from cerebrovascular causes , even in the absence of valve disease
