Insights
Cardiovascular diseases significantly impact the vestibular system. Recent myocardial infarction patients showed fewer vertigo symptoms but similar acoustic issues compared to those with older infarctions.
Area of Science:
- Neuroscience
- Otolaryngology
- Cardiology
Background:
- Cardiovascular diseases are prevalent and frequently linked to brain lesions affecting the vestibular system.
- Vestibular system dysfunctions are a common complication of cardiovascular events.
Purpose of the Study:
- To investigate neurootological functional changes in patients following myocardial infarction.
- To compare vestibular and acoustic symptoms in patients with recent versus older myocardial infarctions.
Main Methods:
- Two patient groups were compared: Group A (recent myocardial infarction, within 1 year) and Group B (older myocardial infarction, >1 year).
- Neurootometric assessments included vertigo symptom evaluation, acoustic symptom reporting (tinnitus, hearing loss), butterfly calorigrams, stepping-test craniocorpography (CCG), and bone conduction audiometry.
Main Results:
- Group A reported an average of 1.48 vertigo symptoms per patient, while Group B reported 2.02.
- Tinnitus and hearing loss prevalence was similar between groups (around 45-58%).
- Abnormal neurootometric findings were frequent in both groups, with higher rates of abnormal bone conduction audiometry in Group A.
Conclusions:
- Myocardial infarction impacts neurootological function, with varying symptom and audiological profiles based on time since infarction.
- Further research is needed to understand the mechanisms linking cardiovascular events to vestibular dysfunction.
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%.
