Abstract

Myocardial infarction comprises gross necrosis of the myocardium, as a result of interruption of the blood supply to the area, as in coronary thrombosis. Myocardial infarction may occur when coronary vessels are narrowed or occlude, as the blood supply to the infarcted heart muscle is seriously impaired. Cardiovascular diseases are extremely wide spread and often also cause vestibular system dysfunctions. They are related mainly to the organic lesions of the brain.
It has been established that true vertigo occurs mainly in patients with bad circulation in vertebrobasilar base and may be objectivized by various types of vestibular deficiencies: either peripheral, or central, or both. As the cardiovascular system may be concerned, it is argued whether individuals with cardiovascular diseases are prone to develop a sensorineural deafness. Hearing impairment parallels the incidence of coronary heart disease. But all cardiac patients do not develop hearing loss.
For investigating the neurootological functional changes after myocardial infarction two samples from our patients were compared of whom group a.) suffered of a myocardial infarction only within one year prior to our neurootmetric investigation (42 persons, 92,86% males and 7,14% females) and group b.) with an infarction more than one year before examination (104 patients, 81,73% males and 18,27% females). Counting the 6 most important vertigo symptoms per patient in group a.) 1,48 signs per patient and in group b.) 2.02 signs per patient were found. With respect to the acoustic symptoms they complained in group a.) 45,24% about tinnitus and 52,38% about hearing loss and in group b.) 48,08% about tinnitus and 58,65% about hearing loss. The functional neurootometric measurements unveil the following pathologies: in group a.) 80,95% in the butterfly-calorigrams, 64,29% in stepping-CCG, 40,48% in bone conductional audiometry in the right side and 52,38% in the left ear audiograms and in group b.) 78,85% in the butterfly-calorigrams, 61,54% in stepping-CCGs, 28,85% in right and 41,35% in left bone conductional audiograms.
