Left ventricular hyperophy is caused by all except aEUR'
MS Left ventricular hyperophy is enlargement of the muscular tissues of the hea. Left ventricular hyperophy develops in response to some chronic hemodynamic overload resulting either from hypeension or faulty valves. The extra work of adopting to chronic hemodynamic overload leads to hyperophy of the hea i.e. there is increase in size of the individual muscle .fibre in response to increased demand. The workload is thus shared by a greater mass of cellular components and each muscle fibre is spared excess work. Common conditions that cause left ventricular hyperophy Hypeension (M.C. cause of left ventricular hyperophy Aoic valve stenosis --> obstruction to the flow of blood through Aoic valve causes hea to work hander and results Aoic regurgitation Dilated cardiomyopathy In mitral stenosis, hyperophy is seen in left atrium and right ventricle.
