Association between epistaxis and hypertension is controversial. In this study, we evaluated in hypertensive patients the incidence of epistaxis according to stages of hypertension and compared blood pressure (BP) readings in these episodes to routine readings. Thirty-six patients admitted to the Emergency Department (ED) with epistaxis were enrolled and divided into 3 groups according to hypertension severity (JNC-VI criteria). BP readings were obtained weekly (routine BP) and in the setting of a new episode of epistaxis (epistaxis BP). No difference in the incidence of epistaxis was found: patients with hypertension stage 1 had 7.6+/-4.1 episodes/year, those in stage 2 had 8.0+/-4.0 and in stage 3 the incidence was 8.2+/-3.9 (p=ns). The average SBP for all 36 patients was 154+/-19 mmHg on routine readings and 157+/-22 mmHg on epistaxes episodes (p=ns). No difference was also observed regarding DBP: 104+/-18 mmHg vs. 105+/-18 mmHg (p=ns). In conclusion, epistaxis incidence in hypertensive patients is not associated to hypertension severity. Moreover, BP readings in the setting of epistaxis are similar to readings obtained in routine situations.
鼻出血与高血压之间的关联存在争议。在这项研究中，我们评估了高血压患者根据高血压分期的鼻出血发生率，并将这些发作时的血压（BP）读数与常规读数进行了比较。36 名因鼻出血而到急诊部（ED）就诊的患者被纳入研究，并根据高血压严重程度（JNC-VI 标准）分为 3 组。每周（常规 BP）和新发作鼻出血时（鼻出血 BP）获得血压读数。我们发现鼻出血的发生率无差异：高血压 1 期患者每年发生 7.6+/-4.1 次，2 期患者为 8.0+/-4.0 次，3 期患者为 8.2+/-3.9 次（p=ns）。所有 36 名患者的平均 SBP 在常规读数时为 154+/-19mmHg，在鼻出血发作时为 157+/-22mmHg（p=ns）。DBP 也无差异：104+/-18mmHg 与 105+/-18mmHg（p=ns）。总之，高血压患者的鼻出血发生率与高血压严重程度无关。此外，鼻出血发作时的血压读数与常规情况下获得的读数相似。
