Abstract

Introduction

To describe the characteristics of patient’s presenting with postpartum hypertension, comparing those with known hypertensive disorders of pregnancy (HDP) antenatally to patients presenting with de novo postpartum hypertension.

Methods

A retrospective audit of deliveries at Northern Health from January 2016 to December 2020. International Classification of Diseases (ICD) codes combined with a manual medical records search identified 72 records that resulted in representation to hospital with hypertension. Data was collected to observe and compare maternal, pregnancy and fetal characteristics.

Results

Of the 72 patients, 35 (48.6 %) readmissions had known HDP and 37 (51.4 %) had de novo postpartum HDP. Similarities were observed between both the patients with known HDP and de novo postpartum hypertension group, including maternal age at delivery (32.4 ± 4.9, 31.9 ± 5.6 years), BMI (32 (25–38), 31 (24–41) kg/m²) and nulliparity (48.6 %, 40.5 %). Aspirin prescription was similar in both groups (28.6 %, 27.0 %). The mean birthweight of the known HDP group was significantly less (2893.7 ± 231.4 g) compared to the de novo group (3362.4 ± 584.4 g). Differences were observed in the urine protein to creatinine ratio (uPCr) antenatally. Antenatally and postpartum the blood pressure readings for the known HDP were significantly higher than the de novo group.

Conclusions

More than 50 % of patients representing are de novo HDP. It does not appear pre-eclampsia is unrecognised antenatally in the de novo group. Our study does not highlight key factors that aid the recognition of those at risk of developing postpartum hypertension separate to the risk factors that are associated with HDP generally.

妊娠期高血压疾病患者与产后高血压患者的比较

前言：描述产后高血压患者的特点，将产前已知妊娠高血压疾病（HDP）患者与产后新发高血压患者进行比较。方法对2016年1月至2020年12月在北方卫生院分娩的产妇进行回顾性审计。国际疾病分类（ICD）代码结合人工医疗记录搜索确定了72例高血压患者到医院就诊的记录。收集资料，观察和比较产妇、妊娠和胎儿的特征。结果72例患者中，35例（48.6%）为已知HDP， 37例（51.4%）为产后新发HDP。已知HDP组与产后高血压新发组在分娩年龄（32.4±4.9、31.9±5.6岁）、BMI（32（25-38）、31 (24-41)kg/m2）、无产（48.6%、40.5%）等方面存在相似之处。两组阿司匹林处方相似（28.6%,27.0%）。已知HDP组的平均出生体重（2893.7±231.4 g）明显低于新生组（3362.4±584.4 g），产前尿蛋白/肌酐比值（uPCr）也有差异。产前和产后已知HDP的血压读数明显高于新生组。结论超过50%的患者为新发HDP。在新生儿组中，先兆子痫并没有在产前被忽视。我们的研究并没有强调那些有助于识别产后高血压风险的关键因素，而不是与HDP相关的危险因素。

期刊介绍： Pregnancy Hypertension: An International Journal of Women''s Cardiovascular Health aims to stimulate research in the field of hypertension in pregnancy, disseminate the useful results of such research, and advance education in the field. We publish articles pertaining to human and animal blood pressure during gestation, hypertension during gestation including physiology of circulatory control, pathophysiology, methodology, therapy or any other material relevant to the relationship between elevated blood pressure and pregnancy. The subtitle reflects the wider aspects of studying hypertension in pregnancy thus we also publish articles on in utero programming, nutrition, long term effects of hypertension in pregnancy on cardiovascular health and other research that helps our understanding of the etiology or consequences of hypertension in pregnancy. Case reports are not published unless of exceptional/outstanding importance to the field.
