Adjusted single load exercise test. A new exercise test for improved diagnosis of coronary heart disease.
A new adjusted single load exercise test (ASLET) is presented. The test is aimed to improve diagnosis of coronary heart disease and should not be used in patients with a well-established diagnosis. 60--120 min after a multistage near-maximal ergometric test with a negative electrocardiographic outcome ASLET is performed. The single load used in ASLET is based on the last load reached at the multistage procedure. If for example a heart rate of 150 beats/min (end point parameter of the multistage test for the age group above 40 years) is reached at 100 W (after performing 25, 75, and 100 W) the ASLET will be a sudden load of 100 W. This procedure has proved to increase the sensitivity of our exercise test. In about one third of false negative results at the multistage procedure the ASLET test was positive in symptomatic patients.
