Overview
Progressive sensorineural hearing loss-hypertrophic cardiomyopathy syndrome is an extremely rare genetic condition that affects both the ears and the heart. People with this syndrome gradually lose their hearing over time due to damage to the inner ear's nerve pathways (called sensorineural hearing loss). At the same time, the heart muscle becomes abnormally thick, a condition known as hypertrophic cardiomyopathy (HCM). The thickened heart muscle can make it harder for the heart to pump blood efficiently and may lead to symptoms such as shortness of breath, chest pain, fatigue, and in some cases, dangerous heart rhythm problems. The hearing loss in this condition typically gets worse over time, starting with difficulty hearing certain pitches and progressing to more significant hearing impairment. The heart involvement can range from mild thickening with few symptoms to more serious complications that require close monitoring and treatment. Because this syndrome is so rare, there is no specific cure. Treatment focuses on managing symptoms: hearing aids or cochlear implants may help with hearing loss, while medications, lifestyle modifications, and sometimes surgical procedures are used to manage the heart condition. Regular monitoring by both ear specialists and heart doctors is essential to track how the disease progresses and adjust treatment as needed.

Gradual hearing loss that worsens over timeThickening of the heart muscleShortness of breath, especially during exerciseChest pain or discomfortHeart palpitations or irregular heartbeatFatigue and low energyDizziness or lightheadednessFainting episodesDifficulty understanding speech, especially in noisy settingsRinging in the ears (tinnitus)
Autosomal dominant
Passed on from just one parent; each child has about a 50% chance of inheriting it
