IHSS heart Meaning
Idiopathic hypertrophic subaortic stenosis (IHSS), also known as hypertrophic obstructive cardiomyopathy (HOCM), is a medical condition in which the heart muscle becomes abnormally thickened (hypertrophied), especially in the area of the left ventricle, which is the chamber of the heart responsible for pumping blood to the body. This thickening can cause narrowing (stenosis) of the pathway for blood to leave the heart and can also cause problems with the heart's ability to relax and fill with blood.
IHSS heart Symptoms
The symptoms of idiopathic hypertrophic subaortic stenosis (IHSS) can vary depending on the severity of the condition, but common symptoms may include:
- Shortness of breath, especially during exercise or physical activity
- Chest pain, discomfort or pressure
- Fainting, dizziness, or lightheadedness, particularly with exertion or after standing up
- Palpitations or rapid heartbeat
- Fatigue or weakness
- Difficulty breathing while lying flat
IHSS heart Causes
The exact cause of idiopathic hypertrophic subaortic stenosis (IHSS) is not fully understood. However, there are several factors that may contribute to the development of the condition, including:
Genetic mutations
In some cases, IHSS may be inherited in an autosomal dominant pattern, meaning that a person only needs to inherit one copy of the mutated gene from one parent to develop the condition.
Abnormal protein production
People with IHSS may have abnormal protein production in the heart muscle, leading to excessive thickening of the heart muscle.
High blood pressure
Chronic high blood pressure can cause the heart muscle to thicken and become stiff, which may increase the risk of developing IHSS.
Aging
As people age, the heart muscle may naturally thicken, which can increase the risk of developing IHSS.
Unknown factors
In some cases, the cause of IHSS may be unknown (idiopathic).
