Heart valve insufficiency may cause insomnia. Commonly, there are mitral, aortic, and pulmonary valve insufficiency. 1. Mitral valve insufficiency: It may lead to mitral valve regurgitation, which reduces the amount of blood discharged from the heart and manifests itself as fatigue, weakness, and decreased endurance for activities, etc. It may also cause pulmonary venous stasis, which leads to nocturnal paroxysmal dyspnea and sedentary respiration, etc., and causes insomnia when it strikes in the middle of the night. 2. Aortic Closure Insufficiency: After the aortic valve itself is diseased, the diastolic aortic blood flow refluxes into the left ventricle, causing the end-diastolic pressure of the left ventricle to rise rapidly, which leads to pulmonary stasis, pulmonary edema and other discomforts. Suddenly, dyspnea, inability to lie down, sweating and other symptoms will occur, thus causing insomnia. 3. Pulmonary Valve Closure Insufficiency: It is mainly due to the abnormal structure and function of the valve of the pulmonary artery, resulting in pulmonary hypertension; it usually causes palpitations (accelerated heartbeat, often accompanied by panic), chest pain, dyspnea, pain in the liver area and other discomforts, and it may cause insomnia if it occurs at night when chest pain and pain in the liver area may appear after the onset of insomnia. If the above symptoms occur, it is recommended to go to the hospital in time for early and regular treatment.
