Cardiorespiratory fitness as a predictor of nonfatal cardiovascular events in asymptomatic women and men.
Prospect i ve data relating cardiorespiratory fitness ( CRF ) with nonfatal cardiovascular disease ( CVD ) events are limited to studies in men or studies of combined fatal and nonfatal CVD endpoints . The authors examined the association between CRF and nonfatal CVD events in 20,728 men and 5,909 women without CVD at baseline . All participants performed a maximal treadmill exercise test  and completed a follow-up health survey in the Aerobics Center Longitudinal Study ( Dallas , Texas ) between 1971 and 2004 . There were 1,512 events in men and 159 events in women during an average follow-up of 10 years . Across incremental CRF groups , age- and examination year-adjusted event rates per 10,000 person-years were 107.9 , 75.2 , and 50.3 in men ( p(trend ) < 0.001 ) and 41.9 , 27.7 , and 20.8 in women ( p(trend ) = 0.002 ) . After further adjustment for smoking , alcohol intake , family history of CVD , and abnormal exercise electrocardiogram responses , hazard ratios were 1.00 ( referent ) , 0.82 ( 95 % confidence interval ( CI ) : 0.72 , 0.94 ) , and 0.61 ( 95 % CI : 0.53 , 0.71 ) in men , p(trend ) < 0.001 , and were 1.00 ( referent ) , 0.74 ( 95 % CI : 0.49 , 1.13 ) , and 0.63 ( 95 % CI : 0.40 , 0.98 ) in women , p(trend ) = 0.05 . After adjustment for other CVD predictors , the association remained significant in men but not in women
