Sam Morton: Living With Heart Disease

I've discovered that most of the time, my life with a chronic disease can be much like everyone else's. I am 41 years old. I am a father, husband, uncle, nephew, and son. I am an ex-cop.

The faster you receive treatment with thrombolytic therapy (if appropriate), the quicker blood flow will be restored to the area and the greater the chance to prevent long-term damage, or even death.
