Here are some HCM basics that everyone should know:
- On average, we live as long as anyone else when we properly care for our HCM.
- We are more likely to get good care at a high-volume center – an HCMA-Recognized Center of Excellence. The American College of Cardiologists and the American Heart Association guidelines for HCM agree about high-volume centers.
- Most people have a few symptoms that are easily managed with medications.
- If you are a member of the HCMA Facebook Group, remember that those of us who seek support from the group often have more problems related to HCM. If you are newly diagnosed, you may be alarmed by what some are going through. Just know that your HCM may not be as dire as some accounts you read online.
- HCM is characterized by a thickening of the heart muscle (hypertrophy means “to thicken”). Even with minimal thickening, though, we can have symptoms due to heart muscle stiffness and other factors caused by myocardial disarray , which means the heart muscle cells aren’t lined up normally.
