Left ventricular hypertrophy is the enlargement of leftover ventricle of the sum . provide heart ventricle , which is responsible for for pump oxygenize stemma throughout the body via aorta , is enlarged due to excess accent or workload on it because of several reasons . The thickening of the heart muscle may lead to weakening , stiffening or red ink of snap of the heart muscles that may boil down the blood flow from the heart ventricle to the circulatory system . LVH can conduct to increase risk of fortuity , heart attack or sudden cardiac check .
Left ventricular hypertrophy is mostly secondary to other pathology . The most usual cause of odd ventricular hypertrophy is continuing hypertension , found in more than 1/3rd people with hypertension . The other causes include aortal valve stenosis ( narrowing of the aortic valve ) , aortic valve puking , hypertrophic cardiomyopathy , acrobatic training , slumber apnea , diabetes , arrhythmia , atrial fibrillation and enlargement of aorta .
The node of the left ventricle is an adjusting / conform mechanism associate to pressure overload junior-grade to above causes , which over fourth dimension can cause stiffening or weakening of heart muscle and serious cardiac or systemic issue . These include reduce blood provision to the fondness and other torso constituent , abnormal heart rhythm , irregular heartbeat , short supply of O to the heart , stroke , shortness of breathing place , loss of consciousnessand cardiac arrest .
ab initio , left ventricular hypertrophy may gift with no symptoms , but with sentence when the condition worsens and gets stern , the symptoms start manifest in the form ofchest painfulness , truncation of breath , fatigue , dizzinessand palpitations .
What is Cardiomyopathy?
Cardiomyopathy is a disorderliness of the structure and function of myocardial pump muscle with no signs of high blood pressure , coronary artery disease , valvular , inborn centre disease or any extra work load on spunk . It can be classified into other eccentric , namely , hypertrophic cardiomyopathy , lucubrate cardiomyopathy , arrhythmogenic cardiomyopathy and restrictive cardiomyopathy . Cardiomyopathy carries mellow morbidness and fatality rate charge per unit and is the reason for sudden death in immature someone and athlete .
Hypertrophic cardiomyopathy is inherited as an autosomal dominant disorder that is characterise by disorientation of cardiac myocytes stimulate by mutation in genes responsible for for encode sarcomeric protein ( cardiac beta - myosin , troponin and alpha - tropomyosin ) . Hypertrophic cardiomyopathy lead to enlargement of the myocardium of leftover ventricle causing leftover ventricular hypertrophy . The hypertrophy is generally present in the anterior ventricular septum , although it can be found in any part of unexpended ventricle . This go to impaired diastolic filling and mental defectiveness in mitral valve do impediment of blood flowing from left ventricle , diastolic dysfunction , myocardial ischaemia and risk of infection for arrhythmias .
Hypertrophic cardiomyopathy may introduce with no symptom to wicked symptom of dyspnoea ( shortness of breathing space ) , faint , chest pain , palpitations , arrhythmias and decreased ability to exercise .
Is Left Ventricular Hypertrophy Same As Cardiomyopathy?
Thus , both these terms , leave ventricular hypertrophy and cardiomyopathy are bigger and are not cut back to each other . Cardiomyopathy is sub - classified into other types , one of which is hypertrophic cardiomyopathy that may cause left ventricular hypertrophy . Left ventricular hypertrophy caused due to hypertrophic cardiomyopathy is genetical in nature and is not secondary to any pathology that might cause pressure overload on left ventricle . It is simply a mutation in the genes creditworthy for proper orientation course of sarcomeres , which form the brawn of the unexpended heart ventricle . This leads to thickening of the left over ventricle muscle .
Whereas , left ventricular hypertrophy does not only let in hypertrophic cardiomyopathy , but also it is caused junior-grade to other conditions and disease that increase the workload on remaining ventricle . This increased work load on left heart ventricle causes the remaining ventricle to ferment hard , thus , causing the heftiness to thicken , stiffen and undermine with metre . Hypertrophic cardiomyopathy is just one of the causes of remaining ventricular hypertrophy . Therefore , it would be improper to say left ventricular hypertrophy and cardiomyopathy are the same , as both these footing have a broader meaning and are not restricted to one another , but intend much more than just their modified law of similarity of remaining ventricular thickener .
