Hello! Thank you for your question on HCM! I understand your concern and would explain that the most important thing on keeping well with this situation is to build an appropriate strategy for the optimal treatment of coronary disease (probably by percutaneous angioplasty) and heart failure. Regarding life expectancy it will depend on the success of management and prevention of new ischemic attacks and heart failure. Cardiac ultrasound gives an important information about that. The most important predictors are Left ventricular performance (ejection fraction) and presence of co-morbidity; if predictors are not severely compromised a surgical option would give a more steady solution. If you have concrete information about the full medical history and exams (including ECHO) I could give a more objective opinion. Hope to have been helpful to you! Greetings. Dr. Iliri
