Summary
Increased left ventricular wall thickness in hypertensive patients is linked to impaired longitudinal systolic function. This dysfunction is detectable even with subtle structural changes, highlighting the importance of monitoring ventricular hypertrophy.
Area of Science:
- Cardiology
- Cardiovascular Imaging
- Heart Failure Research
Background:
- The transition from left ventricular (LV) hypertrophy to heart failure involves complex subcellular events.
- The precise point at which structural abnormalities induce myocardial dysfunction remains unclear.
Purpose of the Study:
- To investigate the relationship between LV wall thickness and longitudinal systolic dysfunction.
- To identify echocardiographic markers for early detection of systolic dysfunction in hypertensive patients.
Main Methods:
- Prospective study involving clinical assessment and transthoracic echocardiography.
- Recruited 226 hypertensive patients and 101 healthy individuals.
- Analyzed left ventricle ejection fraction (LVEF), global longitudinal strain (GLS), and mitral annulus plane systolic excursion (MAPSE).
Main Results:
- Hypertensive patients with LV hypertrophy showed reduced GLS and MAPSE compared to healthy individuals.
- LV septum thickness ≥13 mm was associated with decreased GLS, and ≥14 mm with decreased MAPSE.
- LV septum thickness was the sole variable linked to longitudinal systolic dysfunction (OR=1.1, P=0.001).
Conclusions:
- Progressive LV wall thickening correlates with longitudinal systolic dysfunction.
- Moderate to severe ventricular hypertrophy (septum ≥13 mm) indicates longitudinal systolic dysfunction.
- Left ventricle ejection fraction is insensitive for detecting early longitudinal myocardial dysfunction in hypertension.

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...

01:29Heart Failure II: Pathophysiology
96
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...

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...

Dilated cardiomyopathy, or DCM, is a progressive myocardial disorder characterized by ventricular chamber dilation and contractile dysfunction.EtiologyVarious factors can cause DCM, including hypertension and heavy alcohol intake, which contribute to the weakening and enlargement of the heart muscle. Viral infections, such as Coxsackievirus B, adenoviruses, and influenza, can lead to DCM by causing inflammation and damage to heart tissue. Certain chemotherapeutic agents, including daunorubicin,...

01:20Mitral Regurgitation I: Introduction
77
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...

118
Cardiomyopathy, or CMP, is a group of diseases affecting the myocardial structure, impairing its ability to pump blood effectively. This condition can lead to arrhythmias, heart failure, or sudden cardiac death.Cardiomyopathies are classified into primary and secondary categories:Primary Cardiomyopathy refers to conditions involving only the heart muscle that are often idiopathic (of unknown cause) or genetic. They primarily affect the myocardium without the involvement of other systemic...
