leave ventricle pump profligate to the aorta which distributes blood to all tissues in the consistency . The core is a muscle and so , like other muscles , it bring forth bigger if it is worked intemperately over time . go forth ventricular hypertrophy ( LVH ) appears when the workload on the heart is excessive and for cope up the muscularity thicken and the heart enlarges . This is called left ventricular hypertrophy .
What Is The Cause Of Left Ventricular Hypertrophy?
Any disease or factor that causes the fondness to work harder than normal to pump blood to your body can cause left ventricular hypertrophy .
disease that can cause your heart to work harder and can make will ventricular hypertrophy include :
High Blood Pressure (Hypertension) Causes Left Ventricular Hypertrophy
Hypertension is by far the primary lawsuit of LVH or will ventricular hypertrophy . More than 40 % of people with hypertension incline to develop LVH during the course of being diagnose with gamy stock pressure . What pass off in high blood pressure is the , force of the roue against your arterial blood vessel rampart increase with time . Then the marrow has to pump lineage to the aorta against a higher pressure . This increase the workload on the bosom .
Blood pressing is check by the amount of ancestry the mettle pumps and the amount of resistance to blood line flowing from your arteries . If your heart pumps in a higher pressure and your arteries are narrow-minded the rakehell pressure will be high .
Aortic Valve Stenosis Can Cause Left Ventricular Hypertrophy
Aortic valveseparates the left ventricle from the large blood vessel that leaves your heart ( aorta ) . It also control the amount of bloodline that is free to the aorta . Aortic valve stenosis appears when the opening of the aortic valve is narrowed and the left ventricle has to work hard to pump blood from a narrow down aortic valve .
aortal stenosis seen unremarkably in older multitude because of scarring and calcium building up in the valve with years . unremarkably age - relate aortic valve stenosis begins after 60 old age .
Most vulgar drive of aortic stricture in young the great unwashed is a parentage defect in the sum valves ( congenital disease ) . It ’s predict bicuspid valve . Where alternatively of the common three cusp in the aortal valve only two cusps are present .
Another Cause of Left Ventricular Hypertrophy is Hypertrophic Cardiomyopathy (HCM)
It ’s a vulgar disease that strike people of any years and it ’s a genetic disease . It dissemble men and cleaning woman equally . HCM appears when the heart muscle cells enlarge and the walls thickens ( chiefly leave alone ventricle ) . The thickening of the left ventricle muscle wall , blocks the pedigree filling and blood pump out of the left ventricle which causes growth workload on the kernel . If this happen it ’s called hypertrophic obstructive cardiomyopathy .
HCM can affect the valve that divides the left aorta form give heart ventricle ( mitral valve ) causing line to leak backward . The entire left heart ventricle may thicken but there will be no blockage to the stock fountain . This is called non - obstructive hypertrophic cardiomyopathy
Athletic Hypertrophy Causes Left Ventricular Hypertrophy
Prolong exercise and strength training can cause affectionateness to thicken the odd heart ventricle musculus to adjust the growth work load . It ’s unclear if this can run to any affectionateness disease .
Risk Factors for Left Ventricular Hypertrophy
The following factors can increase the danger of getting left ventricular hypertrophy :
Conclusion
Left ventricular hypertrophy pass off when the workload on leave behind ventricle increase and in club to keep up with the regular blood pumping the unexpended ventricle sinew thickens and the unexpended heart ventricle enlarges . This makes the left heart ventricle washy and buckram which prevents the blood menses . The causes are hypertension which is the coarse cause , aortic valve stenosis , hypertrophic cardiomyopathy and acrobatic hypertrophy . Risk factors are older age , fleshy , household history , diabetes , African - American airstream and women with hypertension .
