Exercise workload, cardiovascular risk factor evaluation and the risk of stroke in middle-aged men.
OBJECTIVE We investigated the prognostic significance of risk scores and exercise workload with respect to stroke . Background . There are no data on exercise workload combined with European Systematic Coronary Risk Evaluation ( SCORE ) in the prediction of stroke . METHODS  Exercise workload was measured by exercise test with an electrically braked cycle ergometer performed at baseline . The study is based on a r and om population -based sample of 1639 men ( 42 - 60 years ) without history of type 2 diabetes or atherosclerotic cardiovascular disease including coronary heart disease , stroke or claudication . RESULTS During an average follow-up of 16 years , a total of 97 strokes occurred , of which 71 were ischaemic strokes . Independent predictors for all strokes were European SCORE [ for 1 % increment , relative risk ( RR ) : 1.12 , 95 % CI : 1.02 to 1.22 , P=0.017 ) , maximal workload ( for 20 W increment , RR : 0.87 , 95 % CI : 0.80 to 0.95 , P=0.003 ) and body mass index ( for 5 kg m(-2 ) increment , RR : 1.08 , 95 % CI : 1.03 to 1.14 , P=0.004 ) , when adjusted for serum HDL , alcohol consumption , C-reactive protein , family history of coronary heart disease , exercise-induced ST changes and the use of medications for hypertension , dyslipidaemia or aspirin . The risk was 2.54-fold ( 95 % CI : 1.27 - 5.09 , P=0.008 ) for any strokes and 4.43-fold ( 95 % CI 1.69 - 11.78 , P=0.003 ) for ischaemic strokes amongst men with exercise capacity less than 162 W when compared with those with high exercise capacity over 230 W , after adjustment for risk factors . CONCLUSIONS Low exercise workload predicts an especially high risk for stroke in the presence of high risk SCORE
