Value of the 6 minute walk test in predicting multi vessel coronary arterial disease


The 6 minute walk test (6MWT) is well established in the clinical assessment of heart failure, pulmonary hypertension and COPD. Its value as a submaximal stress test in the risk stratification of chronic stable ischaemic syndromes is as yet not validated. 95 patients undergoing coronary angiography for assessment of chronic stable angina performed the 6MWT according to a modified protocol. The gamma correlation test indicated a moderately significant relationship between ECG changes plus symptoms at the end of the 6MWT and multi vessel coronary arterial disease. The T wave changes showed no significant correlation. Hence the 6MWT is a useful tool in the risk stratification of stable ischaemic syndromes which can be safely performed in a general ward prior to hospital discharge. It would be a useful preliminary test before planning a programme of cardiac rehabilitation.
