まとめ

新しい高血圧ガイドラインは、体外受精の成功に影響を与える可能性があります。ステージ1またはステージ2の高血圧の女性は、体外受精中に子供が生まれる確率が低く、妊娠合併症のリスクが高くなりました。これは、妊よう治療における血圧管理の重要性を強調しています。

科学分野:

生殖医療; 心血管健康; 産科

背景:

更新された高血圧ガイドライン（2025年、2017年ACC/AHA）により、診断閾値が130/80 mm Hgに引き下げられました。

研究の目的:

体外受精（IVF）を受けている女性における妊娠前の血圧（BP）レベルと生殖転帰との関連を調査すること。

主な方法:

中国の生殖医療センターにおける後向きコホート研究。

主要な成果:

ステージ1およびステージ2の高血圧の女性は、正常血圧（49.2%）と比較して、有意に低い出生率（46.1%および41.4%）を示しました。
ステージ1およびステージ2の高血圧は、妊娠喪失、妊娠高血圧症、および早産のリスク増加と関連していました。
血圧の上昇は、妊娠高血圧症のリスク増加と関連していました。
最適な血圧のカットオフ値は、ステージ1の高血圧の診断と一致しました。

結論:

妊娠前のステージ1およびステージ2の高血圧は、IVF後の出生率の低下と関連しています。

In Vitro Fertilization

In Vitro Fertilization

In vitro fertilization (IVF) is a form of assisted reproductive technology where an egg is fertilized with sperm in a controlled laboratory environment before transferring the resulting embryo into the uterus. This process is designed to help individuals and couples experiencing difficulties conceiving.
The IVF process begins with ovarian stimulation, during which reproductive endocrinologists prescribe hormonal medications to stimulate the ovaries to produce multiple eggs instead of the single...

Blood Pressure

Blood Pressure

The movement of blood in a human body, commonly referred to as blood flow, is determined by the volume of blood that traverses a certain section of the bodily system per unit time. It is the rhythmic contraction of the heart's ventricles that primarily instigates this movement. As the ventricles contract, blood is forced into the prominent arteries, which then flow from areas of greater pressure to lower pressure areas. This movement continues into smaller arteries and arterioles and...

Blood Pressure

Blood Pressure

Blood pressure (BP) is the pressure or force of blood exerted on the artery's walls as it circulates through the body. It is essential for maintaining blood flow throughout the body.
The average BP in an adult is typically around 120/80 mmHg (millimeters of mercury). In this measurement, the numerator (120) indicates the systolic pressure, which is the pressure in the arteries during the contraction of the heart's ventricles as blood is expelled. The denominator (80) represents the...

Measurement of Blood Pressure

Measurement of Blood Pressure

Assessing blood pressure is a standard procedure executed in virtually all medical environments. The method utilized today was established over a hundred years ago by an innovative Russian doctor, Dr. Nikolai Korotkoff. The soft ticking noise, known as Korotkoff sounds, heard while taking blood pressure readings results from turbulent blood flow within the vessels. The apparatus required for this procedure includes a sphygmomanometer, a blood pressure cuff attached to a gauge, and a...

Factors affecting Blood pressure

Factors affecting Blood pressure

Several physiological and lifestyle factors influence blood pressure (BP). Understanding these factors is crucial as they are significant in patient education and blood pressure management.
Physiological Factors:

Alterations in Blood Pressure

Alterations in Blood Pressure

Alterations in blood pressure, such as hypertension (high blood pressure) and hypotension (low blood pressure), significantly affect human health. Understanding these conditions' classifications, causes, and symptoms is essential for effective management and treatment.
Hypertension (High blood pressure)
Hypertension occurs when blood pressure readings consistently exceed the normal range. It is diagnosed when systolic blood pressure (the top number, indicating pressure while the heart...
