'It turns out that a broken heart is an actual medical condition. Broken heart syndrome occurs during highly stressful or emotional times, such as a painful breakup, the death of a spouse, the loss of a job or extreme anger, said Loyola University Health System cardiologist Dr. Binh An P. Phan. During an extremely stressful event, the heart can be overwhelmed with a surge of adrenalin and other stress hormones. This can cause a narrowing of the arteries that supply blood to the heart. It's similar to what happens during a heart attack, when a blood clot in a coronary artery restricts blood supply to heart muscle. But unlike a heart attack, broken heart syndrome is reversible, Phan said. But it's difficult to distinguish between broken heart syndrome and a heart attack, Phan said. Thus, if you experience symptoms such as chest pain and difficulty breathing, don't assume you're having broken heart syndrome – call 911.' - Adam Crowe
