title: Neurosensory deficits after myocardial infarction.
abstract: Cardiovascular diseases are extremely widespread and often cause vestibular system dysfunctions. They are related mainly to organic lesions of the brain. To investigate neurootological functional changes, we compared two samples from among our patients, of whom those in group A (42 persons: 92.86% male, 7.14% female) had experienced myocardial infarction within 1 year before our neurootometric investigation and those in group B had undergone infarction 1 year or more before examination (104 patients: 81.73% male, 18.27% female). Considering only the six most important vertigo symptoms experienced by patients, we found 1.48 symptoms per patient in group A and 2.02 symptoms per patient in group B. As regards acoustic symptoms, 45.24% of patients in group A experienced tinnitus and 52.38% reported hearing loss. In patients in group B, 48.08% were affected with tinnitus and 58.65% with hearing loss. Abnormalities in the neurootometric measurements were revealed as follows: in group A, butterfly calorigrams, 80.95%; stepping-test craniocorpography (CCG), 64.29%; and bone conduction audiometry on the right side, 40.48%, and on the left side, 52.38%; in group B, butterfly calorigrams, 78.85%; stepping-test CCG, 61.54%; bone conduction audiometry on the right side, 28.85%, and on the left side, 41.35%.
