Summary
Subclinical hyperthyroidism (SCH) impairs left and right atrial function, affecting blood flow dynamics. Thyroid-stimulating hormone (TSH) levels correlate with these atrial function changes in SCH patients.
Area of Science:
- Cardiology
- Endocrinology
- Medical Imaging
Background:
- Subclinical hyperthyroidism (SCH) is a condition that may affect cardiac function.
- Atrial function plays a crucial role in overall cardiovascular health.
Purpose of the Study:
- To evaluate left atrial (LA) and right atrial (RA) phasic function and deformation in subclinical hyperthyroidism (SCH).
- To utilize two- and three-dimensional echocardiography (2DE and 3DE) for assessing atrial function in SCH.
Main Methods:
- Included 45 untreated women with SCH and 45 healthy controls.
- Performed comprehensive 2DE and 3DE examinations to assess atrial function.
Main Results:
- Decreased total and passive LA emptying fractions (EF), increased active EF in SCH.
- Reduced passive RA EF and amplified active EF in SCH.
- TSH correlated with various LA and RA EF parameters and longitudinal strain, with TSH remaining associated with LA conduit/booster pump and RA pump functions after adjustments.
Conclusions:
- Biatrial phasic function is significantly impaired in SCH patients.
- TSH levels demonstrate a correlation with LA and RA conduit and pump functions.

01:23Mitral Stenosis II: Clinical features and Diagnostic Tests
425
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...

687
Hypertrophic cardiomyopathy, or HCM, is an autosomal dominant genetic disorder characterized by asymmetric left ventricular hypertrophy without ventricular dilation. It is more common in men and is typically diagnosed in young, athletic adults.EtiologyHCM is primarily genetic and is caused by mutations in genes encoding sarcomeric proteins. Researchers have identified over 1400 mutations across at least 11 different genes. Among these, the most frequently occurring mutations are found in the...

471
Dysrhythmias, also known as arrhythmias, are disturbances in the heart's rhythm that range from benign to life-threatening. A thorough evaluation is crucial for appropriate management and involves a comprehensive medical history, physical examination, and various diagnostic tests.Medical HistorySymptoms: Collect detailed information on palpitations, dizziness, syncope, chest pain, and fatigue. Note their onset, frequency, and triggers.Previous Cardiac Issues: Document any history of heart...

445
Myocarditis is an inflammation of the heart muscle. The symptoms vary widely, encompassing asymptomatic presentations to severe, acute manifestations.Clinical PresentationAsymptomatic cases: In some instances, myocarditis may be asymptomatic, with the infection resolving without intervention. These cases often go undetected unless discovered incidentally through diagnostic imaging or tests conducted for other reasons.General Early Symptoms: Early symptoms of myocarditis are non-specific and can...

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...

01:20Mitral Regurgitation I: Introduction
989
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...
