[Novel functional stress test (stochastic) and perspectives of its application].
OBJECTIVE
To assess advantages of a stochastic functional stress test during which workloads change according to law of random numbers.


METHODS
Results of stochastic tests and standard stress tests with stepwise increments of workloads were compared in 45 healthy subjects and 90 patients with ischemic heart disease (45 with angina pectoris, 45 after myocardial infarction).


RESULTS
Compared with standard tests stochastic test was characterized by shorter times of achievement of ischemic threshold and higher double product. Sensitivity and specificity of stochastic test were significantly better than those of standard stress test. The difference between results of two tests can be explained by increased information content of the stochastic test.
