Reversible ischemic neurological deficit (RIND) due to exercise testing for the diagnosis of angina pectoris

Abstract

A 57 year old Japanese male with chest oppression due to exercise is presented. This symptom was likely due to effort angina pectoris. Master's double two-step test revealed ischemic ST segment depression on the electrocardiogram, thus, a Tl201 myocardial stress imaging test using a bicycle ergometer was undertaken. Immediately following the exercise test, the patient experienced dizziness and palsy in his left upper and lower limbs. Cerebral angiography demonstrated 70% stenosis at the right internal carotid artery, but no abnormal findings were demonstrated on a cranial x-ray CT scan and magnetic resonance imaging. His palsy in the left limbs completely recovered within 3 weeks. Thus this event was diagnosed as a reversible ischemic neurological deficit (RIND). Major but noncardiogenic complications during exercise testing are very rare, and RIND has not been reported thus far to the best of our knowledge. Copyright © 2003 by the Japanese Heart Journal.
