The European Society of Cardiology (ESC) released the "2024 ESC guidelines for the management of elevated blood pressure and hypertension" on August 30, 2024. This guideline updates the 2018 "Guidelines for the management of arterial hypertension." One notable update is the introduction of the concept of "elevated blood pressure" (120-139/70-89 mm Hg). Additionally, a new systolic blood pressure target range of 120-129 mm Hg has been proposed for most patients receiving antihypertensive treatment. The guideline also includes numerous additions or revisions in areas such as non-pharmacological interventions and device-based treatments for hypertension. This article interprets the guideline's recommendations on definition and classification of elevated blood pressure and hypertension, and cardiovascular disease risk assessment, diagnosing hypertension and investigating underlying causes, preventing and treating elevated blood pressure and hypertension. We provide a comparison interpretation with the 2018 "Guidelines for the management of arterial hypertension" and the "2017 ACC/AHA guideline on the prevention, detection, evaluation, and management of high blood pressure in adults."

Objective:To analyze the willingness and related factors of pregnant women in Shanghai City to receive influenza vaccines during pregnancy.Methods:An online questionnaire survey was conducted among pregnant women who registered in maternal and child health hospitals in 16 districts of Shanghai. The basic information, health status during pregnancy, attitude towards influenza vaccination, and knowledge of influenza and influenza vaccine were collected, and χ2 test and multivariate logistic regression analysis were used to analyze the willingness and related factors of pregnant women to receive influenza vaccines during pregnancy. Results:A total of 3 219 valid questionnaires were received, with 10.90% of pregnant women willing to receive influenza vaccination during pregnancy, 57.50% unwilling to receive vaccination and 31.59% holding an uncertain attitude. Among the pregnant women who were willing to receive the vaccine, 82.91% would take the initiative to know the relevant information about the influenza vaccine, and 87.18% understood the transmission routes of the flu. 32.09% believed that pregnant women could receive the influenza vaccination at any stage of pregnancy. Among those who were unwilling and held an uncertain attitude, the proportions of the above three questions were 47.06%, 83.95% and 17.80%, respectively. Among pregnant women who were unwilling to receive vaccination and held an uncertain attitude, the main reason for their vaccine hesitation was the concern about the safety of the vaccine for pregnant women and fetuses during pregnancy. Multivariate logistic regression analysis showed that pregnant women with higher education ( OR=3.278, 95% CI: 1.678-6.406, P=0.001), second trimester ( OR=1.542, 95% CI: 1.159-2.054, P=0.003), third pregnancy ( OR=2.318, 95% CI: 1.008-5.331, P=0.048), and previous influenza vaccination ( OR=1.552, 95% CI: 1.119-2.152, P=0.008) had a higher willingness to receive influenza vaccines during pregnancy. Conclusion:Pregnant women in Shanghai have a relatively low willingness to receive influenza vaccines during pregnancy, mainly due to concerns about vaccine safety.
