Predictive value of maximal stress test in patients showing atypical or no symptoms of ischaemic heart disease.

A study was carried out on 76 patients attending outpatients' department of medicine, Government Medical College, Nagpur. These patients had either (a) atypical angina or (b) no symptoms but certain factors for ischaemic heart disease. All cases were subjected to maximal stress test. Thirty-five cases (46.05%) showed a positive result on the basis of 'ST' segment depression of 2 mm or more. In the absence of facilities for coronary angiography, treadmill test is an important diagnostic tool for ischaemic heart disease.
