Epistaxis and Clinic Blood Pressure Values: Is There a Relationship?

Introduction: Epistaxis is the most common otorhinolaryngological emergency and historically there have been an important debate whether there is a cause-effect relationship with high blood pressure. Aim: This retrospective study explored whether hypertension is a significant risk factor for epistaxis in Emergency Department (ED) patients and examined associations between blood pressure levels and epistaxis episodes. Materials and Methods: Two groups were studied: Group A (patients with epistaxis) and Group B (control). Patient characteristics, comorbidities, and medication use were recorded. Blood pressure measurements were taken upon ED arrival and after specialist evaluation. Statistical analyses included descriptive statistics, T-test, χ2 test, and logistic regression. Results: Group A, enrolled from April 2014 to February 2015, included 102 patients, mean age 67, male-female ratio 2:1. Blood pressure on arrival was over 140/90 mmHg in 73%, decreasing to 26% after 30 minutes. Group B, enrolled from May 2023 to August 2023, included 126 patients, mean age 59, male-female ratio 2:1. Blood pressure on arrival was over 140/90 mmHg in 60%, decreasing to 23% after 30 minutes. Both groups showed reduced blood pressure post-evaluation. Logistic regression identified anticoagulant and/or antiplatelet therapy as the main independent risk factor for epistaxis. Age, sex, blood pressure levels, and hypertension did not significantly influence epistaxis occurrence. Conclusion: No significant correlation between hypertension and epistaxis was found. Anticoagulant and/or antiplatelet therapy was the primary independent risk factor, highlighting the importance of considering medication history in evaluating epistaxis. [ABSTRACT FROM AUTHOR]
