Hypertension, hypertrophic cardiomyopathy, and aortic stenosis can cause ventricular septal thickening, which can lead to symptoms such as dyspnea, ascites, dizziness, fatigue, and chest pain. Mild ventricular septal thickening can be asymptomatic, but can present with symptoms related to the primary disease. For example, symptoms related to hypertension (dizziness, weakness, blurred vision, etc.), symptoms of hypertrophic cardiomyopathy (chest pain, dyspnea, palpitations, fainting, etc.), and symptoms of aortic stenosis (chest pain, panic, shortness of breath after activity, etc.). With the continuous thickening of the interventricular septum, the outflow tract of blood from the heart is obstructed, the amount of blood ejected into the periphery decreases, and the pressure inside the heart chambers increases, which can lead to symptoms such as dyspnea, hepatosplenomegaly, ascites, and edema of the lower limbs. It is recommended to go to the hospital in time when appealing symptoms appear.
