[Exercise test in patients over 70 years of age].
One hundred and sixty-four out of 171 prescribed tests were carried out (96 p. 100) in 48 women aged 70 to 85 years (mean 74,3 years), and 116 men aged 70 to 84 years (mean 73,4 years). The indications were: coronary artery disease (113 cases), cardiac arrhythmias (44 cases), cardiac failure (12 cases), hypertension (9 cases) and assessment of apparently normal subjects (7 cases). The tests were performed on a bicycle ergometer in the upright position; the work load was increased stepwise every 3 minutes with automatic electrocardiographic recording. 37.2 p. 100 of subjects exceeded 90 p. 100 of the maximal predicted heart rate for age; 23.2 p. 100 failed to achieve 75 p. 100 of the target heart rate. There were no serious complications but 4.2 p. 100 minor incidents occurred. The mean maximum work load was 66,5 watts (71.9 W for men and 53.5 W for women). These results show that exercise testing is possible in geriatric patients and provides information of comparable value to that obtained in younger patients. The investigation is safe when performed under strict medical supervision.
