Why Did The Concentric Remodeling Appear On My Echo?

The study reveals that an increasing degree of concentric remodeling in men, expressed by the M/V ratio, is associated with a decline in left ventricular (LV) volume. Left ventricular hypertrophy is a form of cardiac remodeling that causes the heart wall muscle to thicken, leading to an increase in LV mass (LVM). There are different sub-categories that fall into the diagnosis of LVH, including concentric, eccentric, and concentric remodeling.

Concentric remodeling refers to a process by which increased LV relative wall thickness alters myocardial geometry, resulting in reduced LV end-diastolic. After certain insults to the myocardium, such as an infarction or viral disease, the ventricle may lose its LV end-diastolic volume. In both concentric and eccentric hypertrophy, LVMI is increased, with a normal RWT in eccentric hypertrophy and an increased RWT in concentric. Diastolic heart failure is characterized by a pattern of concentric LV remodeling with a normal or near-normal end-diastolic volume, increased wall thickness and mass, and a high ratio of mass to.

The American Heart Association recommends that the description of LV geometry, using at least the four categories of normal geometry, concentric remodeling, and concentric and eccentric hypertrophy, should be a standard component. Changes in left ventricular geometry are related to the incidence of non-fatal cardiovascular outcomes and long-term mortality.

Several markers may indicate a remodeling process, including changes in the expression of myosin heavy chain isoforms, with an increase in alpha- and a decrease in beta. Concentric remodeling is usually due to high blood pressure or other factors, and early diagnosis of concentric remodeling in hypertension is possible due to inflammation and inflammation. Concentric LVH means the effect of long-term high blood pressure on the heart, and mild concentric LVH should be continued as advised.

What does it mean when the heart is concentric?

Concentric hypertrophy in the heart is a condition characterized by increased pressure overload, often due to hypertension or aortic stenosis. This leads to a decrease in ventricular compliance and diastolic dysfunction, which can eventually result in ventricular failure and systolic dysfunction. Laplace’s law states that wall stress is proportional to the product of transmural pressure and cavitary radius, and inversely proportional to wall thickness.

In response to pressure overload, left ventricular wall thickness increases, while cavitary radius remains relatively unchanged. These compensatory changes, known as “concentric hypertrophy”, reduce the increase in wall tension observed in aortic stenosis.

What is concentric hypertrophy on Echo?

Concentric left ventricular hypertrophy is an abnormal increase in left ventricular myocardial mass due to chronically increased workload on the heart, often resulting from pressure overload induced by arteriolar vasoconstriction. Eccentric left ventricular hypertrophy is induced by increased filling pressure of the left ventricle, known as diastolic overload. This mechanism can play a role in compensating for ischemic or infarcted myocardial tissue in patients with coronary artery disease.

The sustained increase in wall stress, cytokine and neuro-activation, stimulates the development of myocardial hypertrophy or increasing muscle thickness with the deposition of the extracellular matrix. This initially serves as a compensatory mechanism to maintain contractile forces and counteract increased ventricular wall stress. However, the benefits of increased wall thickness are offset by a significant increase in stiffness of the hypertrophied walls and increased diastolic ventricular pressures, which are transmitted back into the left atrium and pulmonary vasculature.

How to treat concentric remodeling?

Heart failure with preserved ejection fraction (HFpEF) is a complex clinical syndrome with various phenotypes and multiple pathophysiologic mechanisms. However, the presence of left ventricular concentric remodeling or hypertrophy is central to the disease process. This study confirms that reduced poststress left ventricular volumes in patients with known HFpEF are associated with reduced measures of CRF. These findings have important therapeutic implications, particularly suggesting that strategies to treat or prevent left ventricular concentric remodeling in patients with HFpEF may improve CRF.

With the growing prevalence of HFpEF worldwide, there is a need for larger, controlled studies to address additional therapeutic approaches to reverse concentric remodeling in this population. The research was funded by a grant from the American Heart Association Scientist Development, National Heart, Lung, and Blood Institute, and internal funds of the VCU Pauley Heart Center and Victoria Johnson Research Laboratories.

Is cardiac remodeling good or bad?

Cardiac remodeling is a group of molecular, cellular, and interstitial changes that occur in the heart after injury, causing changes in size, mass, geometry, and function. This process can lead to poor prognosis due to its association with ventricular dysfunction and malignant arrhythmias. Factors such as cell death, energy metabolism, oxidative stress, inflammation, collagen, contractile proteins, calcium transport, geometry, and neurohormonal activation play a role in cardiac remodeling.

The pharmacological treatment of cardiac remodeling can be divided into three stages: consolidated, promising, and potential strategies. The term “remodeling” was first used in 1982 in an amyocardial infarction (MI) model to describe the replacement of infarcted tissue with scar tissue. In 1990, it was adopted to characterize morphological changes after infarction, particularly an increase in the left ventricle.

In 2000, an international forum on cardiac remodeling defined cardiac remodeling as a group of molecular, cellular, and interstitial changes that manifest as changes in size, shape, and function of the heart resulting from cardiac injury. This article focuses on deleterious, pathological cardiac remodeling.

Is concentric remodeling reversible?

Heart failure syndrome leads to an increase in neurohormonal activity, which is an adaptive mechanism in response to cardiac output. Cardiacremodeling involves changes in ventricular volume and the thickness and shape of the myocardial wall. With optimized treatment, this remodeling can be reversed, causing gradual improvement in cardiac function and improved prognosis. Cardiacremodeling involves changes in ventricular volume and stroke volume, and when it remains increased, it contributes to the intensification of clinical manifestations and myocardial damage.

Is concentric remodeling the same as hypertrophy?

Concentric remodeling is a response to LV hypertrophy, often caused by chronic pressure, volume overload, or MI. It results in systolic dysfunction and changes in LV geometry, with the LV becoming more rounded and diastolic dysfunction rapidly degrading. Key echocardiographic signs of concentric remodeling include increased LV wall thickness, normal or small LV cavity size, normal left ventricular mass, and increased relative wall thickness.

What is evidence of concentric remodeling?

Concentric remodeling is a late stage response to left ventricular hypertrophy, often caused by chronic pressure, volume overload, or a myocardial infarction (MI), which can be due to longstanding hypertension. This remodeling results in systolic dysfunction and changes in the LV geometry, with the LV becoming more rounded and exhibiting rapid degradation of diastolic dysfunction and loss of radial and longitudinal function.

Key echocardiographic signs of concentric remodeling include increased LV wall thickness, normal or small LV cavity size, normal left ventricular mass (LVM), and increased relative wall thickness (RWT).

These findings are crucial in understanding the pathophysiology behind various categories of left ventricular hypertrophy (LVH), which are determined by LV mass (LVM) and relative wall thickness (RWT). To obtain these values, follow the steps provided in the second part of the LVH blog series.

What causes concentric remodelling?

LV remodeling can occur through a number of different physiological and pathological mechanisms. One such mechanism is concentric remodeling, which occurs in response to pressure overload and involves the addition of myocyte sarcomeres in parallel.
