まとめ

エコカルジオグラムは,左心室質量を測定することによって,左心室高縮症 (LVH) を特定することができます. この測定は,成人におけるLVHを診断するために壁の厚さを評価するよりも敏感です.

科学分野:

心臓病学心臓病学
メディカルイマージング (医学イメージング)

背景:

左心室多動症 (LVH) は,重大な心血管疾患である.
LVHの正確な診断は,患者の管理に不可欠です.
エコーカルディオグラフィは,心臓の構造を評価するための主要なイメージング方式です.

研究の目的:

左心室縮症 (LVH) を特定する際の異なるエコーカルディオグラフィのパラメータの感度を評価する.
大人のLVHを診断するための最も効果的なエコー・カルディオグラフィー・メソッドを決定する.

主な方法:

エコカルジオグラムは,心電図による左心室縮症 (LVH) と診断された27人の成人の患者に実施した.
測定には,左心室 (LV) の後壁の厚さ,心室間隔膜の厚さ,LVの寸法,およびLVの質量が含まれています.
標準的なエコーカルディオグラフィック測定とペン・メソッドがLV質量の推定に使用されました.

主要な成果:

背面 LV 壁または隔膜の厚さ (≥12 mm) の増加は,患者の48%のみで LVH を特定しました.
背面壁の膨張 (≥58 mm) は,後部壁の厚さのない患者の33%で観察されました.
標準的な方法を使用した患者の78%で,ペン法を使用した患者の100%で,LV質量のエコーカルディオグラフィの推定値が増加しました.

結論:

左心室質量のエコーカルディオグラフィの推定は,LV壁の厚さよりも,左心室縮症 (LVH) のより敏感な指標である.
増加したLV質量は,LVHの基本的な定義と一致しています.
エコカルジオグラフィのLV質量測定は,LVHの優れた診断精度を提供します.

Heart Sounds

Heart sounds are generated by the turbulence in blood flow due to the closing of heart valves. These sounds are best perceived slightly away from the valves, where the blood flow disseminates the sound.
Auscultation is the process of listening to these internal body sounds using a stethoscope. The heart produces four types of sounds, but only two—S1 and S2—can usually be heard with a stethoscope.
S1, also known as the "lub" sound, is caused by the closure of atrioventricular (A-V) valves at the...

Assessment of the Cardiovascular System IV: Auscultation

Cardiac auscultation is a clinical skill used to assess heart function and detect abnormalities. It involves listening to heart sounds at specific anatomical locations through a stethoscope.
Normal Heart Sounds
S1 (First Heart Sound)-
S1 is made by the closure of the mitral and tricuspid valves (atrioventricular valves), marking the beginning of systole.
S2 (Second Heart Sound)-
S2 is made by the closure of the aortic and pulmonic valves (semilunar valves), marking the end of the systole.

Cardiovascular System Abnormal Findings II: Auscultation

Auscultation, an essential part of a heart examination, is done using a stethoscope. It provides crucial information about heart function and possible heart problems. Due to heart problems, abnormal sounds can be heard during systole or diastole. These sounds include S3 and S4 gallops, opening snaps, systolic clicks, and murmurs.

Mitral Stenosis II: Clinical features and Diagnostic Tests

Mitral stenosis is a heart condition in which the mitral valve, which allows blood to flow from the left atrium to the left ventricle, becomes narrowed or stenotic. This narrowing hinders blood flow and leads to clinical symptoms requiring specific medical evaluations and management strategies. The following overview outlines the clinical symptoms, assessments, diagnostic findings, prevention methods, and treatments for mitral stenosis.Clinical ManifestationsDyspnea (shortness of breath): This...

Aortic Regurgitation II: Clinical Features and Diagnostic Tests

Aortic valve regurgitation (AR) occurs when the aortic valve fails to close properly, allowing blood to flow backward from the aorta into the left ventricle. This backflow can result in two distinct clinical presentations: acute and chronic AR, each characterized by its own set of symptoms and physical findings.Acute Aortic RegurgitationAcute AR presents with a sudden onset of severe symptoms. Patients typically experience profound dyspnea (shortness of breath), chest pain, and signs of left...
