Thank you for providing this service. With hypertrophic cardiomyopathy, there is no specific wall thickness at which you become symptomatic. Many patients with the wall thickness you list are already symptomatic. With HOCM, the average wall thickness is 2.0 cm. In addition, the amount of mitral regurgitation is important.
Age is also an important factor is predicting prognosis, as is family history of the disease.
Your very good exercise capacity is a good sign. I hope this is useful. Feel free to write back. I wish you the best of luck. Information provided in the Heart Forum is intended for general medical informational purposes only.
