title: [Value of the treadmill test, bicycle ergometry test and the isometric test in evaluating the severity of coronary insufficiency].
abstract: Possibilities of the treadmill test, bicycle ergometry and the isometric test are reviewed with respect to the diagnosis and assessment of the severity of coronary heart disease (CHD). A study of 40 normal males and 95 coronary patients (including 57 aneurysm-free ones and 38 with left ventricular postinfarction aneurysm) demonstrated low diagnostic value of standard dynamic load programs for the assessment of coronary insufficiency. An original treadmill test program has been developed where each new step carries a 1 MET increment of the load, allowing to assess the severity of CHD within a wide range of clinical manifestations, and group patients according to the involvement of 1 or 2 coronary arteries. The isometric test is of little value for the diagnosis of CHD, yet it can be useful in the assessment of the severity of coronary insufficiency and identification of patients with the involvement of 2 and 3 coronary arteries.
