まとめ
閉塞性心不全 (CHF) を発症する生涯リスクは,男女ともに5人に1人です. 高血圧は,このリスクを大幅に高め,血圧のコントロールの必要性を強調します.

- 選択されたインデックス年齢における終身CHFリスクの計算.
- 異なる血圧レベルを持つ被験者および心筋梗塞がない場合の心筋梗塞のリスクの比較.
主要な成果:
- 40歳までに心筋梗塞を発症する生涯リスクは,男性では21.0%,女性では20.3%でした.
- 生涯リスクは,増加する罹患率のために,高齢者に対して一貫したままでした.
- 血圧≥160/100mmHgの被験者は,血圧<140/90mmHgの被験者と比較して,生涯にわたるCHFのリスクが2倍であった.
- 前回の心筋梗塞のないCHFの生涯リスクは,40歳で男性では11.4%,女性では15.4%でした.
結論:
- 確立された臨床基準は,男性と女性の両方でCHFの5分の1の生涯リスクを定義しています.

Mitral Regurgitation I: Introduction
1.3K
Mitral regurgitation is characterized by the backward circulation of blood from the left ventricle to the left atrium during systole, a phase of the cardiac cycle when the heart contracts and pumps blood out of the chambers. This abnormal flow occurs primarily due to the dysfunction of the mitral valve or its supporting structures, which include the mitral leaflets, chordae tendineae, annulus, and papillary muscles.Etiology and Mechanisms:Primary Mitral Regurgitation: This type arises from...

Myocarditis is inflammation of the myocardium, which is the muscular layer of the heart.EtiologyMyocarditis has a diverse etiology, including a wide range of infectious and non-infectious causes:Infectious CausesViral: Common viruses include Coxsackie A and B, adenovirus, parvovirus B19, enteroviruses, and influenza A.Bacterial: Examples include infections caused by Streptococcus, Staphylococcus, and Mycoplasma species.Rickettsial: Infections like Rocky Mountain spotted fever can result in...

Rheumatic Heart Disease I: Introduction
1.0K
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...

Heart Failure I: Introduction
1.7K
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...

Heart Failure II: Pathophysiology
1.9K
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...
