title: [Methods of diagnosing unstable stenocardia and monitoring its treatment].
abstract: The informative value of various functional and laboratory diagnostic methods was reviewed in 150 patients with unstable angina (UA). High informativeness (92%) and sensitivity (83%) of isometric hand grip under computerized electrocardiographic monitoring was demonstrated for the diagnosis and control of treatment in these patients. Isometric loading brought out a dramatically reduced coronary reserve, latent heart failure and electrical instability of the myocardium. The cold test with a small area of skin exposure is of low diagnostic value in UA cases and cannot be recommended for clinical use. Serial myoglobin assays add to the accuracy of diagnosis and have high predictive value.
