My parents both had heart disease.
Dad had a heart attack at age 70. Coronary angiography, a stent placed through his wrist, a pacemaker/defibrillator and amazing providers allowed his life to be extended by 9 years.
Mom had a pacemaker, an ablation, and again amazing providers that extended her life for many years.
These are examples of how the American Heart Association's research is improving and extending lives.
