まとめ
血圧薬を夕方投与すると,朝投与と比較して心血管疾患は減少しません. このメタ解析では,高血圧患者の夕方投与の有意な効果は認められませんでした.
科学分野:
- 心臓病科
- 薬理学について
- 臨床試験
背景:
- 抗高血圧薬の投与の最適なタイミングは,心血管疾患の減少に関して議論されている.
- 既存のランダム化された証拠は,夕方と朝の投与の利点を明らかにするために統合する必要があります.
研究 の 目的:
- 抗高血圧薬の夕方と朝の投与を比較したランダム化対照試験 (RCT) を体系的にレビューし,メタ分析する.
- 主要な心血管疾患の有害事象およびその他の臨床結果に対する薬剤投与タイミングの影響を評価する.
主な方法:
- MEDLINE,EMBASE,CENTRALのデータベースを徹底的に検索した.
- 高血圧患者46, 606人を対象とした5つのRCTが含まれており,追跡期間の中央値は5. 2年であった.
- 試験レベルのデータのメタ解析は,ランダム効果モデルを使用して,偏差リスクの低い試験の感度分析を行った.
主要な成果:
- 抗高血圧薬の夕方の投与は,朝の投与と比較して重大な心血管疾患の有害事象を有意に減少させなかった (HR,0. 71; 95% CI,0. 43 - 1. 16).
- バイアスのリスクが低い試験に限定された分析も,有意な差異を示さなかった (HR,0. 94; 95% CI,0. 86- 1. 03).
- 全体的な分析では高い異質性 (I2=94%) が観察されました.
結論:
- 抗高血圧薬の夕方投与は,高血圧の成人の朝投与と比較して,心血管疾患の減少をもたらしません.
- 抗高血圧治療の現在のタイミング戦略は,主要な心血管疾患の結果に影響しない可能性があることを示唆しています.

Blood pressure monitoring is a crucial clinical procedure in diagnosing and managing various cardiovascular conditions. Despite its significance, the accuracy of blood pressure measurements can be compromised by multiple factors, potentially leading to either falsely high or low readings. These inaccuracies are critical as they can significantly impact patient care. So, it is vital to understand these challenges deeply and adopt strategic approaches to minimize errors.

Multiple classes of antihypertensive medications are employed in treating hypertension. The most commonly recommended first-line treatments include:Thiazide Diuretics, such as chlorthalidone, increase sodium and water excretion from the body, reducing blood volume and blood pressure.Angiotensin-converting enzyme inhibitors, like lisinopril, block the conversion of angiotensin I to II, a potent vasoconstrictor lowering blood pressure.Angiotensin II Receptor Blockers (ARBs) prevent angiotensin II...

3.1K
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...
