衰弱在主动脉瓣狭窄(AS)患者中非常普遍。然而,AS严重程度对衰弱的影响仍不明确。本研究旨在阐明该人群中AS严重程度与衰弱之间的关联。这项回顾性研究纳入了连续因主动脉瓣狭窄住院并拟接受经导管主动脉瓣植入术(TAVI)的患者。比较严重AS与极重度AS患者之间衰弱的患病率、N末端B型利钠肽原(NT-proBNP)水平、步速及老年营养风险指数(GNRI)。采用多因素逻辑回归分析探讨AS严重程度与衰弱之间的关联。共纳入137例患者。严重AS组与极重度AS组之间的衰弱患病率差异无统计学意义(31% vs 30%)。两组间步速与GNRI亦无显著差异,但极重度AS组的NT-proBNP水平显著高于严重AS组(P < 0.01)。多因素逻辑回归分析显示,AS严重程度与衰弱无显著关联;而步速减慢和GNRI降低则与衰弱显著相关,且独立于年龄、性别及心力衰竭因素(极重度AS:比值比[OR] 1.051,95%置信区间[CI] 0.439–2.517;步速降低:OR 5.109,95% CI 1.556–16.775;营养不良:OR 2.841,95% CI 1.145–7.049)。这些结果提示,在该人群的衰弱管理中,除针对AS的治疗外,可能还需辅以低强度运动训练和营养干预。

Atherosclerosis II: Clinical manifestations and prevention

Atherosclerosis is a progressive disorder that leads to the thickening and narrowing of arterial walls due to plaque buildup. This condition can cause various symptoms depending on the arteries affected:Coronary Artery Disease (CAD): This condition affects the coronary arteries and may lead to chest pain (angina), shortness of breath (dyspnea), heart attacks, and other heart disease symptoms.Cerebrovascular Disease: This affects blood flow to the brain, causing transient ischemic attacks (TIAs)...

Pathophysiology of Heart Failure01:17

Pathophysiology of Heart Failure

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...

Heart Failure IV: Classification and Diagnostic Evaluation

Heart failure can be classified in various ways, with the most common classifications based on physical activity limitations, disease progression, severity, and treatment strategies.The Functional Classification of Heart Failure divides patients into four categories based on physical activity limitation due to symptom burden.Class I: Patients in this class have cardiac disease but no physical activity limitations. Ordinary activities like walking, climbing stairs, or routine tasks do not cause...

Aneurysm II: Clinical Manifestations and Diagnostic Studies

Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...

Heart Failure III: Clinical Manifestations

Heart failure (HF) manifests primarily as dyspnea, fatigue, and fluid retention, resulting in peripheral and pulmonary edema. Symptoms may vary depending on which ventricle is more affected, left or right.Left-Sided Heart FailureAlso known as left ventricular failure, this condition results from the left ventricle's inability to fill or eject sufficient blood into the systemic circulation. It leads to pulmonary congestion, which occurs when the left ventricle fails to eject blood effectively...

Mitral Stenosis I: Introduction

Mitral Valve Stenosis (MVS) is a heart condition where the mitral valve narrows, impeding blood circulation from the left atrium to the left ventricle. The etiology and pathophysiology of this condition are multifaceted, leading to a cascade of cardiovascular complications.Causes of Mitral Valve StenosisRheumatic Heart Disease: It is the main cause of mitral valve stenosis, particularly in developing nations. This condition arises from rheumatic fever, an inflammatory illness resulting from...
