まとめ
リウマチ性関節炎 (RA) は,心不全 (HF) のリスクを大幅に増加させ,特に心不全はエジェクション分数保存 (HFpEF) を伴います. 治療の進歩にもかかわらず,RA患者のHFリスクは,時間の経過とともに改善されていません.
科学分野:
- 心臓病科
- リウマトロジ
- 公衆衛生
背景:
- リウマチ性関節炎 (RA) は慢性炎症性疾患で,心血管疾患の罹患率が増加する.
- 心不全 (HF) は重大な合併症であり,保存されたエジェクション分数 (HFpEF) と減少したエジェクション分数 (HFrEF) を有するHFには明確なリスクがある.
研究 の 目的:
- RA患者とRA患者との比較で,HFpEFとHFrEFのリスクと時間的な傾向を評価する.
- RA の集団内のHF リスクに影響を与える要因を特定する.
主な方法:
- 退役軍人保健局のデータ (2000年−2019年) を用いた遡及的マッチングコホート研究.
- RA患者は,年齢,性別,入学年数でRA以外の対照群とマッチした.
- HFの発生率とHF関連の死亡は,左心室のエジェクション分数のデータを用いて分類され,HFのリスクはコックス回帰で評価され,混同因子を調整した.
- RA 診断期間を分層化して分析した時間的傾向
主要な成果:
- RAは,HFpEF (aHR 1. 51) とHFrEF (aHR 1.34) のリスク増加と,それに関連する死亡と関連していました.
- 高度な炎症と血清陽性RAを有するRA患者では,HFのリスクがより高かった.
- 研究期間 (2000年−2017年) において,HFリスクの有意な改善は認められなかった.
結論:
- リウマチ性関節炎は,心不全,特にHFpEFの重大なリスクをもたらします.
- RAの治療における現在の進歩は,HFのリスクを減少させていない.
- RA患者におけるHFの標的型予防と管理戦略の開発には,さらなる研究が不可欠です.

Rheumatic heart disease or RHD is a chronic condition that results from rheumatic fever, causing permanent damage to the heart valves.Etiology and Risk FactorsIt primarily arises from rheumatic fever, an inflammatory disease that can develop after untreated or inadequately treated group A streptococcal (GAS) pharyngitis. Streptococcus spreads through direct contact with oral or respiratory secretions. While the bacteria are the causative agents, factors like malnutrition, overcrowding, poor...

The key clinical manifestations of Rheumatic heart disease (RHD) include several distinct cardiac symptoms.Carditis, a hallmark of acute rheumatic fever, involves inflammation of the heart's endocardium, myocardium, and pericardium. Chronic RHD often results from recurrent episodes of carditis. Its symptoms include the following:Murmurs are caused by valvular damage, especially to the mitral and aortic valves. Mitral stenosis or regurgitation is common, with characteristic heart murmurs...

Rheumatic heart disease (RHD) management can be divided into two main strategies: prevention and long-term management.Primary PreventionPrimary prevention focuses on timely diagnosis and management of group A streptococcal pharyngitis to prevent acute rheumatic fever. The most widely used antibiotic for treating this condition is intramuscular benzathine penicillin G.Acute Rheumatic Fever TreatmentThe primary treatment goal for a patient diagnosed with acute rheumatic fever is to suppress the...

AssessmentA comprehensive assessment is essential in managing a patient with rheumatic heart disease (RHD). Begin with obtaining a detailed medical history, including recent streptococcal infections, a history of rheumatic fever, or previously diagnosed rheumatic heart disease. Assess the patient for symptoms such as fever, chest pain, widespread joint pain (arthralgia), tachycardia, pericardial friction rub, muffled heart sounds, heart murmurs, peripheral edema, subcutaneous nodules, and...

01:17Pathophysiology of Heart Failure
1.8K
Heart failure (HF) is a progressive syndrome involving ventricles that leads to inadequate cardiac output. It can be classified based on location and output or ejection fraction. Ejection fraction (EF) is an essential measurement in the diagnosis and surveillance of HF. Reduced EF corresponds to systolic heart failure (HFrEF). However, HF with preserved ejection fraction (HFpEF) is becoming increasingly prevalent. Also known as diastolic HF, this form of HF is related to aging. The...

01:27Heart Failure I: Introduction

Heart failure refers to a clinical syndrome caused by structural or functional cardiac disorders that prevent the heart from pumping an adequate amount of blood to meet the body's metabolic needs. This condition often arises from myocardial infarction or ischemia, leading to decreased cardiac output, reduced tissue perfusion, impaired gas exchange, fluid volume imbalance, and decreased functional ability.Heart failure can result from disruptions in the mechanisms that regulate cardiac output...
