Left ventricular hypertrophy with secondary repolarization abnormalities as seen on ECG Histopathology of (a) normal myocardium and (b) myocardial hypertrophy. Scale bar indicates 50 μm. Gross pathology of left ventricular hypertrophy. Left ventricle is at right in image, serially sectioned from apex to near base.
The diagnosis of left ventricular outflow tract obstruction is usually made by echocardiographic assessment and is defined as a peak left ventricular outflow tract gradient of ≥ 30 mmHg. [ 35 ] Another, non-obstructive variant of HCM is apical hypertrophic cardiomyopathy ( AHCM or ApHCM ), [ 37 ] also called Yamaguchi syndrome .
Ventricular hypertrophy (VH) is thickening of the walls of a ventricle (lower chamber) of the heart. [ 1 ] [ better source needed ] Although left ventricular hypertrophy (LVH) is more common, right ventricular hypertrophy (RVH), as well as concurrent hypertrophy of both ventricles can also occur.
Ventricular remodeling may include ventricular hypertrophy, ventricular dilation, cardiomegaly, and other changes. It is an aspect of cardiomyopathy, of which there are many types. Concentric hypertrophy is due to pressure overload, while eccentric hypertrophy is due to volume overload. [6]
Left axis deviation per se does not require treatment, however the underlying cause can be treated. [5] If left ventricular hypertrophy is the cause of LAD, treatment depends on the underlying cause of the hypertrophy.
[1] [4] left ventricular hypertrophy (LVH) is defined as an abnormal increase in LVM, an important independent risk factor for cardiovascular morbidity and mortality. [5] [6] [7] LVM is also an independent risk factor for cardiovascular disease even within the normal limits. [8] A reduction in LVM following antihypertensive treatment or aortic ...
Left ventricular hypertrophy. Hypertensive heart disease is the result of structural and functional adaptations [18] leading to left ventricular hypertrophy, [19] [20] [21] diastolic dysfunction, [18] [20] CHF (Congestive Heart Failure), abnormalities of blood flow due to atherosclerotic coronary artery disease [18] and microvascular disease, [10] [19] and cardiac arrhythmias. [19]
Also, the diabetic patient may show subtle signs of diabetic cardiomyopathy related to decreased left ventricular compliance or left ventricular hypertrophy or a combination of both. A prominent "a" wave can also be noted in the jugular venous pulse, and the cardiac apical impulse may be overactive or sustained throughout systole .
