OBJECTIVE To study relationships between changes in solar and geomagnetic activity and a course of unstable angina pectoris with neuron nets. METHODS Heliogeophysical variables were studied in 67 male patients at the age of 42 to 75 years with unstable angina pectoris. RESULTS The neuronetwork analysis has revealed marked non-linear relations between angina episodes and heliogeophysical factors. CONCLUSIONS Small-amplitude changes in solar and geomagnetic activity may influence the course of unstable angina pectoris.
