Summary
Sudden sensorineural hearing loss (SSNHL) may be linked to subclinical atherosclerosis. Increased intima media thickness and HSCRP levels were observed in SSNHL patients, suggesting a potential vascular component.
Area of Science:
- Otolaryngology
- Cardiovascular Medicine
- Vascular Biology
Background:
- Sudden sensorineural hearing loss (SSNHL) affects 2-3% of ENT referrals.
- Vascular disorders and compromised perfusion are potential predisposing factors for SSNHL.
- This study investigates atherosclerotic changes and risk factors in SSNHL patients.
Purpose of the Study:
- To explore the association between subclinical atherosclerosis and SSNHL.
- To identify cardiovascular risk factors in patients with SSNHL.
- To compare atherosclerotic markers between SSNHL patients and controls.
Main Methods:
- A case-control study involving 30 SSNHL patients and 30 controls.
- Assessment of cardiovascular risks: medical history, physical examination, blood pressure, BMI, waist circumference, ECG, blood sugar, lipids, and HSCRP.
- Carotid artery color Doppler ultrasound to measure intima-media thickness (IMT).
Main Results:
- SSNHL patients exhibited significantly higher IMT and HSCRP levels compared to controls (P=0.005 and P=0.001, respectively).
- No significant differences were found in smoking history, waist circumference, fasting blood sugar, lipid profile, or ECG between groups.
- Interestingly, controls had higher blood pressure and BMI than SSNHL patients.
Conclusions:
- Subclinical atherosclerosis may be associated with sudden sensorineural hearing loss.
- Elevated IMT and HSCRP suggest a role for vascular changes in SSNHL.
- Further research is warranted to elucidate the relationship between atherosclerosis and hearing loss.

Atherosclerosis is a progressive disorder that leads to the thickening and narrowing of arterial walls due to plaque buildup. This condition can cause various symptoms depending on the arteries affected:Coronary Artery Disease (CAD): This condition affects the coronary arteries and may lead to chest pain (angina), shortness of breath (dyspnea), heart attacks, and other heart disease symptoms.Cerebrovascular Disease: This affects blood flow to the brain, causing transient ischemic attacks (TIAs)...

Atherosclerosis is a progressive disorder characterized by the buildup of plaques on the arterial inner wall, causing them to narrow and harden over time. These plaques comprise lipids, calcium, blood components, carbohydrates, and fibrous tissue. The process primarily affects the intima of large and medium-sized arteries, reducing blood flow in any artery.Etiology and risk factorsThe cause of atherosclerosis is multifactorial, involving a complex interplay among endothelial injury, lipid...

Coronary Artery Disease (CAD): An Overview with Scientific InsightsCoronary Artery Disease (CAD), often referred to as C-A-D, is a prevalent blood vessel disorder classified under the broader category of atherosclerosis. Atherosclerosis is a pathological process characterized by the hardening and narrowing of arteries due to the accumulation of atherosclerotic plaques. These plaques are composed of cholesterol, fatty substances, inflammatory cells, calcium, and fibrin, reducing blood flow to...

Nursing management for a patient with arteriosclerosis involves a comprehensive approach focusing on lifestyle modification, disease monitoring, education, and symptomatic care. Here is an overview of effective nursing strategies:Assessment and Monitoring: Initial and ongoing assessments are crucial. Nurses must document the patient's medical history, including any hypertension, diabetes, hyperlipidemia, and other cardiovascular diseases. Assessments also cover family history and lifestyle...

Coronary Artery Disease (CAD) originates from a series of events that impair the function of coronary arteries, the blood vessels responsible for delivering oxygen-rich blood to the heart muscle. The pathophysiology of CAD is closely linked to atherosclerosis, a chronic inflammatory and lipid-driven condition affecting the vascular endothelium.1. Endothelial DamageThe process begins with damage to the vascular endothelium, which serves as a protective barrier between the blood and the vessel...

Peripheral artery disease (PAD) predominantly results from atherosclerosis, which involves the accumulation of fatty deposits, or plaques, within the walls of arteries. This causes them to narrow and harden, significantly reducing blood flow. PAD predominantly affects the legs, particularly the arteries supplying the thighs and calves. In rare cases, it may involve other arteries, including those in the arms.Etiology of PAD:The principal cause of PAD is atherosclerosis, which results from fatty...
