Insights
Carotid artery stenting (CAS) significantly improves health-related quality of life (HRQoL) in dizzy patients with severe carotid stenosis. This procedure offers a better quality of life for individuals experiencing dizziness due to carotid stenosis.
Area of Science:
- Neurology
- Vascular Surgery
- Quality of Life Research
Background:
- The impact of severe carotid stenosis on health-related quality of life (HRQoL) is not well-understood.
- Dizziness is a common symptom in patients with carotid stenosis, affecting their daily lives.
Purpose of the Study:
- To evaluate the effect of carotid stenting (CAS) on HRQoL in patients with severe carotid stenosis who experience dizziness.
- To compare HRQoL outcomes between patients undergoing CAS and normal controls.
Main Methods:
- Prospective study involving patients with symptomatic (≥60%) or asymptomatic (≥80%) severe carotid stenosis and dizziness undergoing CAS.
- Utilized two validated questionnaires: the 36-item Short-Form Health Survey (SF-36) and the Dizziness Handicap Inventory (DHI).
- Assessed patients 1 week before CAS and 6 months post-procedure, with 20 asymptomatic volunteers serving as controls.
Main Results:
- Patients with severe carotid stenosis and dizziness reported significantly lower HRQoL scores compared to controls on both DHI and SF-36.
- Following CAS, patients demonstrated significant improvements in multiple HRQoL domains, including role physical, bodily pain, general health, social function, and role emotional.
- Forty-one patients completed the 6-month follow-up, showing positive changes in their quality of life post-intervention.
Conclusions:
- Carotid stenting is an effective treatment for improving health-related quality of life in patients suffering from dizziness associated with severe carotid stenosis.
- The study highlights the positive impact of CAS on functional and emotional well-being in this patient population.
Background:
Little is known about the impact of severe carotid stenosis on health-related quality of life (HRQoL). The aim of this study was to assess the effects of carotid stenting (CAS) on HRQoL in dizzy patients with carotid stenosis.
Methods:
Patients with symptomatic (≥60%) or asymptomatic (≥80%) severe carotid stenosis and who complained of dizziness and received CAS were recruited. Two HRQoL questionnaires-a generic survey, the 36-item Short-Form Health Survey and a disease-specific instrument, the Dizziness Handicap Inventory-served as outcome measures. Patients were followed 1 week prior to CAS and 6 months postprocedurally.
Results:
CAS was performed in 178 consecutive patients, 61 of whom complained of dizziness. Forty-one patients (67.2%, 34 male; mean age, 73.3 ± 10.5 years; range, 47-87 years) completed the study. Twenty asymptomatic volunteers (17 male; mean age, 70.3 ± 9.3 years; range, 54-84 years) served as normal controls. Compared to controls, patients tallied lower scores in the overall total and three subscales (physical, functional, and emotional) of the Dizziness Handicap Inventory (p < 0.01). Similar findings were noted in seven out of eight domains of the 36-item Short-Form Health Survey score. After 6 months, CAS resulted in significantly improved HRQoL (role physical, bodily pain, general health, social function, and role emotional) in these patients.
Conclusion:
CAS resulted in improved HRQoL in patients with severe carotid stenosis who experienced dizziness.
