Information on Idiopathic Hypertrophic Subaortic Stenosis (IHSS)

Idiopathic hypertrophic subaortic stenosis (IHSS) most general form of heart muscle disease is hypertrophic cardiomyopathy.

Idiopathic hypertrophic subaortic stenosis (IHSS) also known as Hypertrophic cardiomyopathy. Idiopathic hypertrophic subaortic stenosis (IHSS) is a disease characterized by marked hypertrophy of the left ventricle, involving in particular the interventricular septum and the left ventricular outflow tract. During systole, the hypertrophied muscle in the outflow tract often narrows this region sufficiently to produce obstruction to left ventricular ejection.

In hypertrophic cardiomyopathy, the enlargement and arrangement of muscle fibers are abnormal, leading to thickened heart walls. The most thickening tends to happen in the left ventricle (the heart's central pumping chamber), especially in the septum, the wall that separates the left and right ventricles. The thickening reduces the size of the pumping chamber and obstructs blood flow. It also prevents the heart from properly relaxing between beats and so filling with blood. Types of Hypertrophic cardiomyopathy includes ASH and HOCM. Idiopathic hypertrophic subaortic stenosis (IHSS) is slightly more common in males than in females.

Modifying genetic, hormonal, and environmental factors may lead to a higher likelihood of identification in males. Idiopathic hypertrophic subaortic stenosis (IHSS) usually presents at a younger age in females. Females be likely to be more symptomatic and are more probable to be disabled by their symptoms than males. There are lots of treatment of Idiopathic hypertrophic subaortic stenosis various include lifestyle changes, medications, pacemakers and surgery. Various drugs are used to treat this disease. They comprise beta blockers, calcium channel blockers, antiarrhythmic medications, and diuretics.

Pacemakers vary the pattern and reduce the force of the heart's contractions. The pacemaker can diminish the degree of obstruction and so relieve symptoms. Surgery generally calls for removal of part of the thickened septum (the muscle wall separating the chambers) that is blocking the blood stream. Surgery to eliminate the thickening eases symptoms in about 70 percent of patients but results in death in about 1 to 3 percent of patients. Also, about 5 percent of those who have surgery develop a slow heartbeat, which is then corrected with a pacemaker.
