ABSTRACT
Objective:To explore diagnostic value of 6min walking test (6MWT) for coronary heart disease (CHD) . Methods :A total of 192 patients suspected of CHD ,including 123 men and 69 women ,who were treated in our hos‐pital ,were selected .After hospitalization ,all patients received 6MWT and coronary angiography (CAG) examina‐tion .With CAG results as the gold standard for diagnosing CHD ,sensitivity ,specificity ,accuracy ,positive predic‐tive value and negative predictive value of 6MWT diagnosing CHD were calculated ,and they were compared be‐tween men and women .Detections of 6WMT among groups of different diseased number of vessels were compared . Results :With CAG results as the standard ,accuracy ,specificity ,sensitivity ,positive predictive value and negative predictive value of 6MWT diagnosing CHD were 71.35% ,80.58% ,60.67% ,72.97% and 70.34% respectively . Compared with female patients ,there were significant rise in accuracy (57.97% vs .77.24% ) ,sensitivity (39.29%vs .70.49% ) ,specificity (70.73% vs .83.87% ) and positive predictive value (47.83% vs .81.13% ) , P0.05) .Compared with single - and double -vessel coronary disease ,there was significant rise in true positive rate (43.75% ,54.05% vs .100% ) of triple - or multi -vessel coronary disease diagnosed by 6MWT , P< 0.01 both . Conclusion:The 6min walking test possesses high specificity and sensitivity diagnosing CHD ,and its diagnostic value is higher for male patients and patients with serious condition .Its procedures are sim‐ple with low cost and no damage to patients ,which can be used as adjunctive examination for CHD diagnosis and ex‐tended in clinic .
