Summary
Elevated serum galectin-1 levels are linked to left ventricular diastolic dysfunction (DD) and increased risk of heart failure with preserved ejection fraction (HFpEF) and mortality in patients with angina.
Area of Science:
- Cardiology
- Biochemistry
- Inflammation Research
Background:
- Galectin-1, a glycan-binding protein, exhibits anti-inflammatory effects.
- Left ventricular diastolic dysfunction (DD) is a critical factor in heart failure and mortality.
- The complex pathophysiology of DD necessitates further investigation into associated biomarkers.
Purpose of the Study:
- To investigate the association between serum galectin-1 levels and DD.
- To explore the relationship between serum galectin-1 levels, DD, and incident heart failure with preserved ejection fraction (HFpEF).
- To assess the prognostic value of galectin-1 in patients with angina pectoris.
Main Methods:
- Prospective enrollment of 258 patients with angina pectoris symptoms.
- Assessment of serum galectin-1 levels and echocardiographic parameters.
- Evaluation of a composite endpoint including all-cause mortality or new-onset HFpEF.
Main Results:
- Patients with higher galectin-1 levels showed increased left ventricular mass, left atrial diameter, and DD prevalence.
- Elevated galectin-1 levels were significantly associated with the composite endpoint (p=0.039).
- High galectin-1 remained a significant predictor of DD (OR 2.44, p=0.005) and was linked to poorer survival (log rank p=0.043) after adjustment.
Conclusions:
- Elevated serum galectin-1 levels are associated with left ventricular diastolic dysfunction.
- Higher galectin-1 levels predict an increased risk of all-cause mortality and incident HFpEF.
- Galectin-1 may serve as a potential biomarker for adverse cardiovascular outcomes in patients with angina.

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
2.0K
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...

01:27Heart Failure I: Introduction
126
Heart failure refers to a clinical syndrome caused by structural or functional cardiac disorders that prevent the heart from pumping an adequate amount of blood to meet the body's metabolic needs. This condition often arises from myocardial infarction or ischemia, leading to decreased cardiac output, reduced tissue perfusion, impaired gas exchange, fluid volume imbalance, and decreased functional ability.Heart failure can result from disruptions in the mechanisms that regulate cardiac output...

86
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...

01:20Mitral Regurgitation I: Introduction
79
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...

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...
