Summary
Two-dimensional speckle-tracking echocardiography (2D-STE) reveals impaired left atrial (LA) function in heart failure with preserved ejection fraction (HFpEF). A global longitudinal LA strain during ventricular systole (GLAs-res) value below 17.5% aids in diagnosing HFpEF.
Area of Science:
- Cardiology
- Medical Imaging
- Echocardiography
Background:
- Heart failure with preserved ejection fraction (HFpEF) presents with heart failure symptoms despite normal ejection fraction.
- Left atrial (LA) volume and function are notably impaired in HFpEF patients.
- Two-dimensional speckle-tracking echocardiography (2D-STE) allows for precise quantification of LA deformation dynamics.
Purpose of the Study:
- To evaluate the diagnostic utility of 2D-STE in identifying HFpEF.
- To assess left atrial function using 2D-STE in patients with suspected HFpEF.
Main Methods:
- Eighty-three patients with suspected HFpEF were analyzed according to current guidelines.
- Diastolic dysfunction parameters, including left ventricular mass index (LVMI) and LA volume index (LAVI), were assessed.
- 2D-STE parameters, specifically global longitudinal LA strain during ventricular systole (GLAs-res), were measured.
Main Results:
- Significant differences in BNP, LVMI, deceleration time (DT), LAVI, and GLAs-res were observed between groups.
- GLAs-res showed strong negative correlations with BNP (r = -0.567) and DT (r = -0.665).
- Logistic regression identified GLAs-res (OR=0.71), BNP (OR=1.08), and LAVI (OR=1.59) as independent predictors of HFpEF.
Conclusions:
- Left atrial function, quantified by 2D-STE, is demonstrably impaired in HFpEF.
- A GLAs-res value below 17.5% is a valuable diagnostic marker for HFpEF.
- 2D-STE offers a promising approach for the diagnosis of HFpEF.

1.3K
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...

01:17Pathophysiology of Heart Failure
4.4K
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...

01:20Mitral Regurgitation I: Introduction
885
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...

The heart's primary function is to pump blood throughout the body, maintaining a balance between blood sent out (cardiac output) and blood returning (venous return). If this balance is disrupted, it can result in congestive heart failure (CHF), a severe condition where the heart becomes an inefficient pump, leading to inadequate blood circulation.
CHF can occur due to the failure of either side of the heart. Left-side failure leads to pulmonary congestion—the right side continues to send...

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...

1.1K
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...
