まとめ
低レニンまたは高レニン対アルドステロンの比率によって示されるサブクリニック原発アルドステロニズムは,心血管疾患のリスクを高めます. この関連性は血圧とは無関係であり,標的型スクリーニングと治療の必要性を示唆している.
科学分野:
- 心血管医学
- 内分泌学
- 流行病学
背景:
- 主要アルドステロニズム (PA) は,心血管疾患の増加と関連しています.
- 軽度のPAは一般的だが,心血管リスクとの関連は不明である.
研究 の 目的:
- サブクリニカル・プライマリ・アルドステロニズムマーカーと主要な心血管疾患 (MACE) の関連性を調査する.
主な方法:
- CARTaGENEコホートからの2017年のカナダ人成人の (40-69歳) 展望調査.
- 測定されたアルドステロン,レニン,およびアルドステロンとレニンの比率 (ARR)
- MACE (心筋梗塞,脳卒中,心不全の入院,心血管疾患による死亡) の管理データベースにリンクされ,追跡期間中位は10. 8年.
主要な成果:
- 低レニンと高いARRは,血圧に関係なく,MACEのリスク増加と関連していました.
- 最適な値が特定された:レニンは4. 0ng/ Lで,ARRはng/ Lあたり70 pmol/ Lで,MACEのリスクが高いと予測された.
- アルドステロン濃度はMACEと有意に関連しませんでした.
結論:
- 血圧に関係なく,特定のレニンとARR値によって特定されるサブクリニカルPAは,MACEリスクの上昇と関連しています.
- サブクリニカルPAの早期発見と治療が心血管疾患のリスクを減らすことができるかどうかを確認するには,さらなる研究が必要です.

Hypertension III: Clinical Manifestations and Diagnostic Studies
54
Hypertension is asymptomatic and also referred to as the "silent killer" until it progresses to a severe stage or causes target organ disease. Patients may experience symptoms stemming from the strain on blood vessels and tissues in various organs or the heart's increased workload.Physical exams might show no abnormalities other than high blood pressure. Signs of vascular damage, when present, correspond to the organs supplied by the affected vessels, leading to target organ damage. For...

Antihypertensive Drugs: Action of β1 Blockers
618
β1-receptors are primarily located in the heart and kidneys. In cardiac myocytes, these receptors interact with neurotransmitters released by the sympathetic nervous system during heightened activity or danger. As a result, β1-receptors get activated, initiating a series of biochemical processes. Excessive activation of beta receptors due to chronic stress can abnormally increase heart rate and contractility, resulting in high blood pressure or hypertension. To counteract this,...

Heart Failure Drugs: Inhibitors of Renin-Angiotensin System
516
The activation of the sympathetic nervous system and the renin-angiotensin-aldosterone system (RAAS) contributes to cardiac remodeling, and inhibiting the RAAS is a pharmacological target in heart failure management. As a result, neurohumoral modulation is a crucial treatment principle for managing heart failure. This approach involves using medications like ACE inhibitors (ACEIs), angiotensin receptor blockers (ARBs), β-blockers, mineralocorticoid receptor antagonists (MRAs), and neutral...

Hypertension and Regulation of Blood Pressure
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...

Hypertension II: Pathophysiology
90
Hypertension is a chronic condition in which the blood's force against artery walls is excessively high, posing risks such as heart disease. The condition's underlying mechanisms involve complex interactions among the cardiovascular, kidney, and autonomic nervous systems.Renin-Angiotensin-Aldosterone System (RAAS): This system significantly influences blood pressure regulation. When blood pressure decreases, the kidneys secrete renin. This enzyme transforms angiotensinogen, a plasma protein,...

Heart Failure II: Pathophysiology
51
Systolic Heart Failure and Compensatory MechanismsSystolic heart failure (also termed HFrEF, Heart Failure with Reduced Ejection Fraction) is the most prevalent type of heart filure. It results in a decreased volume of blood being pumped from the ventricle. The aortic arch and carotid sinuses have baroreceptors that detect reduced blood pressure, triggering the sympathetic nervous system (SNS) to release epinephrine and norepinephrine. Initially, this response aims to boost heart rate and...
