resistance training induces physiological concentric cardiac hypertrophy, and could be used as a good exercise modality to compare physiological and pathological concentric hypertrophy in biochemical, molecular and cellular analyses. Eccentric cardiac hypertrophy induced by endurance training In dynamic exercise, in which athletes perform isotonic
Left ventricular hypertrophy in athletes and hypertensive ...
concentric or eccentric hypertrophy, or a combinationof concentric or eccentric hypertrophy,1 with a varying combinationof increase in LV wall thickness and LV diastolic and systolic dimensions (Table 2). In a recent publicationfrom the Dallas Heart Study where 31% of the populationwas hypertensive, the prevalence of concentric LVH was much ...
Concentric or Eccentric Hypertrophy: How Clinically ...
Whether modifications of LV geometry from concentric to eccentric are beneficial beyond the reduction of LV mass has been debated; however, the conclusion has been, in general, that concentric LV hypertrophy is also characterized by greater LV mass than eccentric LV hypertrophy; therefore, these 2 features (ie, concentric geometry and LV hypertro-
Differences in Left Ventricular Diastolic Dysfunction ...
Left ventricular (LV) hypertrophy (LVH) may be eccentric or concentric (2 × LV posterior wall thickness relative to LV end-diastolic dimension ≤ 0.42 or > 0.42, respectively). The LV diastolic function between age-matched hypertensive patients with eccentric and concentric LVH was compared in the present study. Echocardiography was used to ...

patients with concentric LVH had positive ECG criteria RI or RaVL > 2.0 mV four and half times more frequently than those with eccentric LVH, with sensitivities of 9% and 2% respectively. In comparison to the precordial voltages, the R wave amplitude in leads I and aVL are less likely to be affected by the proximity of the heart to the chest wall.

that the training is of sufficient intensity and duration (athlete’s heart). Predominantly eccentric left ven-tricular (LV) hypertrophy is observed in sports with high dynamic and low static demands (e.g. running). Sports with high static demands (e.g., weight lifting) lead to predominantly concentric hypertrophy. In
A 4-Tiered Classification of Left Ventricular Hypertrophy ...
we classified concentric hypertrophy when concentricity0.67 was greater or equal to the above sex-specific thresholds and eccentric hypertrophy when below those values. In 3 different sensitivity analyses, we defined LVH based on LV mass/BSA using previously published values13 and defined increased indexed LVEDV using

Pathophysiology: Heart Failure Mat Maurer, MD Associate Professor of Clinical Medicine Objectives At the conclusion of this seminar, learners will be able to: 1. Define heart failure as a clinical syndrome 2. Define and employ the terms preload, afterload, contractilty, remodeling, diastolic dysfunction, compliance, stiffness and capacitance. 3.

cardiac hypertrophy that occurs in the athlete’s heart is not typically associated with fibrosis (23, 43), cardiac dysfunction (79), or the development of heart failure (see Ref. 59). Concentric vs. Eccentric Cardiac Hypertrophy Exercise-induced physiological hypertrophy can be broadly defined as concentric or eccentric (66). Ec-
