Ever heard of Heart Failure? Is it a heart attack? Or maybe a new way for referring to heart disease? Heart failure is Canada’s most prevalent and most costly chronic disease, with hospital care alone costing close to $10 billion annually. Every five minutes someone with heart failure in Canada dies, and it is estimated more than 600,000 Canadians currently suffer from it. Yet, health professionals often fail to diagnose and treat it, and most of us don’t even know it exists.
