Summary
Advancing age is linked to proportional left ventricular (LV) geometric remodeling, while male sex influences absolute LV dimensions. Standard cardiac MRI measurements can identify these age-related changes.
Area of Science:
- Cardiology
- Medical Imaging
- Human Physiology
Background:
- Left ventricular (LV) geometry adapts to aging and sex.
- Cardiac magnetic resonance (CMR) offers precise assessment but often focuses on volumetric data.
- Linear indices from standard CMR reports are underutilized for evaluating age and sex influences on LV structure.
Purpose of the Study:
- To assess the impact of age and sex on LV geometry.
- To utilize standard CMR linear indices like wall thickness and LV end-diastolic diameter (LVEDD).
- To investigate proportional indices such as relative wall thickness (RWT) and wall thickness-to-LVEDD ratio (WT/LVEDD).
Main Methods:
- Retrospective cross-sectional study of 95 adult patients undergoing CMR.
- Analysis of LV wall thickness, LVEDD, RWT, and WT/LVEDD ratio.
- Stratification by sex and age groups (18-40, 41-60, >60 years) with statistical comparisons.
Main Results:
- Males exhibited significantly larger LVED and greater LV wall thickness.
- Age positively correlated with mean LV wall thickness and WT/LVEDD ratio.
- Age independently predicted concentric remodeling (OR=1.041 per year), while male sex predicted larger LVED.
Conclusions:
- Advancing age is independently associated with proportional LV geometric remodeling.
- Male sex primarily influences absolute ventricular dimensions.
- Standardized linear CMR measurements effectively detect age-related concentric remodeling in clinical practice.

Cardiomyopathy III: Hypertrophic Cardiomyopathy
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...
Aortic Regurgitation II: Clinical Features and Diagnostic Tests
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...
Heart Failure II: Pathophysiology
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...
Mitral Stenosis II: Clinical features and Diagnostic Tests
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...
