[Mathematical analysis of informative criteria for the differential diagnosis of renovascular hypertension and essential hypertension].
Retrospective clinical and mathematical analysis of 168 parameters was performed in 188 patients with arterial hypertension, using standard programmed case history format designed specifically for the purpose. A number of differential criteria were identified and their diagnostic informative value was assessed for each form of arterial hypertension. The isolated criteria were grouped into anamnestic, clinical-laboratory, radioroentgenographic and roentgenoangiographic ones. Anamnestic and clinical-laboratory groups of diagnostic criteria were shown to be acceptable for health services. Their use in prehospital screening of patients is expected to contribute to the diagnosis of basic disease provoking arterial hypertension.
