Exercise workload, coronary risk evaluation and the risk of cardiovascular and all-cause death in middle-aged men
Background No data exist on exercise workload combined with European Systematic Coronary Risk Evaluation ( SCORE ) with respect to death from cardiovascular diseases and other causes . We therefore investigated the prognostic significance of risk scores and exercise capacity with respect to cardiovascular diseases . Design A population -based follow-up study . Methods Exercise workload was measured by exercise test with an electrically braked cycle ergometer . The study is based on a r and om population -based sample of 1639 men ( 42–60 years ) without history of type II diabetes or atherosclerotic cardiovascular disease including coronary heart disease , stroke or claudication . Results During an average follow-up of 16 years , a total of 304 overall deaths and 116 cardiovascular deaths occurred . Relative risk ( RR ) was 2.50 [ 95 % confidence intervals ( CI ) : 1.71–3.68 , P < 0.001 ] for all-cause death and 2.04 ( 95 % CI : 1.14–3.65 , P = 0.016 ) for cardiovascular death among men with exercise capacity less than 162W as compared with those with exercise capacity over 230 W , after adjustment for risk factors . Independent predictors for all-cause death were European SCORE ( for 1 % increment , RR : 1.15 , 95 % CI : 1.10–1.20 , P < 0.001 ) , exercise workload ( for 20W increment , RR : 0.86 , 95 % CI : 0.82–0.91 , P < 0.001 ) , C-reactive protein and alcohol consumption , when adjusted for serum high-density lipoprotein , body mass index , family history of coronary heart disease , exercise-induced ST changes and the use of medications for hypertension , dyslipidemia or aspirin . Conclusion Low  exercise  workload predicts an especially high risk for death from cardiovascular and any other cause when combined with high risk SCORE
