The Prevalence of Dysphonia and Dysphagia Symptoms in Patients on Statin Therapy

Abstract

To investigate the effect of statin therapy on swallowing and phonation. A group of patients on statin therapy and another group not on statins (controls) presenting to the endocrinology clinic between January 2018 and April 2018 were asked to participate. All patients filled Voice Handicap Index (VHI-10), Eating Assessment Tool (EAT-10), and Likert scales for vocal fatigue and hoarseness. Demographic data included age, gender, allergy, and history of smoking. A total of 160 patients were recruited, 75 patients on statin therapy and 85 not on statin therapy. The mean age of the study group was 55.00 years, whereas that of the control group was 45.70 years. The mean duration of statin treatment was 74.92 months. The mean VHI-10 and EAT-10 scores were significantly higher in the statin group compared to the control group (P < 0.05). Although there was no significant difference in the mean Likert scale for vocal fatigue, the mean Likert scale for hoarseness was significantly higher in the statin group compared to the control group (P < 0.05). This investigation revealed a significantly higher prevalence of laryngopharyngeal symptoms in patients on statin therapy versus a control group.
