Heart Series: Why the heart breaks with Dr. Gary Chan

The heart is the energy source of our entire body. It pumps blood rich in oxygen and nutrients to the rest of our body – to our brains, our hands and to all the vital organs. But if something happens to the heart, the rest of the body suffers. And when the heart breaks, it can be fatal. Gary Chan, DO, PhD, cardiologist at MercyOne Siouxland Heart and Vascular Center, helps explain symptoms of a broken heart and why time is critical.
