Summary
Many aortic stenosis (AS) patients are diagnosed only after symptoms appear, increasing cardiovascular event risk. Early detection through methods like auscultation is crucial for timely intervention and better outcomes in AS management.
Area of Science:
- Cardiology
- Clinical Medicine
- Diagnostic Imaging
Background:
- Aortic stenosis (AS) is linked to cardiovascular events, making early diagnosis critical.
- Limited data exist on symptom status, AS severity at diagnosis, and routine detection methods.
- Understanding diagnosis timing and methods is essential for improving patient outcomes.
Purpose of the Study:
- To investigate the timing and methods of initial diagnosis in patients with aortic stenosis (AS).
- To analyze the characteristics of symptomatic versus asymptomatic AS patients at diagnosis.
- To identify factors influencing AS detection in routine clinical practice.
Main Methods:
- Retrospective enrollment of 198 AS patients diagnosed between 1989 and 2009.
- Analysis of patient symptoms, AS severity, and reasons for hospital visit.
- Categorization into symptomatic and asymptomatic groups based on clinical presentation.
Main Results:
- Over half (58.4%) of AS patients were asymptomatic at diagnosis, detected during routine checkups.
- Systolic murmur on auscultation was the most common initial finding in asymptomatic patients (62%).
- Symptomatic patients exhibited greater AS severity and experienced more cardiac events during follow-up.
Conclusions:
- Approximately 40% of AS patients were diagnosed only after symptom development, indicating potential for latent cardiovascular risks.
- Auscultation is a vital tool for the early diagnosis of aortic stenosis.
- Timely diagnosis and intervention are key to mitigating cardiovascular events in AS patients.

874
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...

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...

01:23Mitral Stenosis II: Clinical features and Diagnostic Tests
443
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...

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)...

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...

Diagnosing acute coronary syndrome or ACS begins with a thorough patient history. Notable symptoms include central, crushing chest pain radiating to the left arm, neck, jaw, or back, along with shortness of breath, sweating (diaphoresis), nausea, vomiting, dizziness, and palpitations.It is crucial to note any history of cardiac illnesses and assess risk factors, including age, gender, smoking, hypertension, diabetes, hyperlipidemia, and a sedentary lifestyle.During physical examination, vital...
