Association between Tonsillectomy and Cardiovascular Diseases in Adults

Area of Science:

• Cardiovascular epidemiology
• Surgical outcomes research
• Public health

Background:

• Tonsillectomy is a common surgical procedure.
• The long-term cardiovascular implications of tonsillectomy require further investigation.

Purpose of the Study:

• To investigate the association between tonsillectomy and the incidence of cardiovascular diseases (CVDs) in the Korean adult population.
• To evaluate the risk of stroke, ischemic heart disease (IHD), and heart failure (HF) following tonsillectomy.

Main Methods:

• A retrospective cohort study using data from the Korean National Health Insurance Service-Health Screening Cohort (2002-2015).
• 1082 adult participants (≥40 years) who underwent tonsillectomy were matched with 4328 controls.
• Stratified Cox proportional hazard models were used to calculate hazard ratios (HRs) for CVDs.

Main Results:

• The incidence of stroke was significantly higher in the tonsillectomy group (81.3 vs. 46.6 per 10,000 person-years).
• The incidence of IHD was also significantly higher in the tonsillectomy group (112.3 vs. 64.9 per 10,000 person-years).
• Adjusted HRs showed a 1.78-fold increased risk of stroke and a 1.60-fold increased risk of IHD in the tonsillectomy group. No significant difference in HF incidence was observed.

Conclusions:

• A history of tonsillectomy is associated with an increased risk of stroke and IHD in the Korean adult population.
• These findings suggest a potential link between tonsillectomy and adverse cardiovascular outcomes.
• Further research is warranted to elucidate the underlying mechanisms and clinical implications.
