まとめ
シストリック血圧を130mmHg以下に低下させると,左心房高縮症 (LVH) の高齢の高血圧患者では死亡率が上昇する可能性があります. これらの個人に血圧目標を設定する際には注意が必要です.
科学分野:
- 心臓病学 心臓病学
- 高血圧の研究 高血圧の研究
- クリニック・トライアル 臨床試験
背景:
- 左心室多動症 (LVH) は高血圧の一般的な心臓合併症で,患者の50%までに影響します.
- 既存の高血圧ガイドラインは,LVH患者の血圧目標の管理に関する限られた具体的なガイドラインを提供しています.
- 以前の結果試験は,中年および高齢の高血圧患者で,集中的な血圧低下 (シストリック<130 mmHg) に関する潜在的な安全性に関する懸念を示唆しています.
研究 の 目的:
- LVHの高血圧患者における低収縮血圧の標的と関連した潜在的なリスクをレビューする.
- ECGで定義された高血圧高血圧および異なる血圧目標値を有する高血圧患者の死亡率に関する主要な臨床試験のデータを分析する.
主な方法:
- エンドポイント減少のためのロサルタン介入 (LIFE) 研究 (n=9,193) のデータを分析し,ECG-LVHに焦点を当てた.
- ECG-LVH患者のヴァルサータン抗高血圧剤の長期使用評価 (VALUE) 試験 (n=2,458) のデータの検討.
- 死亡率に関する特定のシストリック血圧値の達成の影響を評価するための時間変動分析.
主要な成果:
- LIFE試験では,シストリック血圧≤130mmHgを達成することは,シストリック血圧≥142mmHgと比較して全因死亡率 (p=0.005) の37%の増加と関連していました.
- VALUE試験では,ECG-LVHで平均シストリック血圧<130 mmHgを達成した患者の全因および心臓死亡率が高かったことが示されました.
- 両試験とも,50歳以上のECG-LVH患者の静脈血圧が130mmHg未満に低下すると死亡リスクが増加することを示唆しています.
結論:
- ECG-LVHを患っている中年および高齢の高血圧患者の静脈動脈血圧<130 mmHgを下げることは,死亡率の増加と関連している可能性があります.
- LVHの高血圧患者にとって最適なシストリック血圧目標を確立するために,さらなる研究が必要である.
- この患者コホートで130mmHg以下の静脈動脈血圧の目標値を検討する際には注意が必要です.

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 (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...

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...

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...

Hypertension, the most common cardiovascular disease, is diagnosed through repeated measurements of elevated blood pressure. Its risks, including damage to the kidney, heart, and brain, are directly proportional to blood pressure levels. Starting from 115/75 mm Hg, the risk of cardiovascular disease doubles with each increment of 20/10 mm Hg. The diagnosis relies on blood pressure measurements, not on patient symptoms, as hypertension is often asymptomatic until end-organ damage is imminent or...
