"A condition called stress cardiomyopathy entails a sudden, temporary weakening of the muscle of the heart (the myocardium). This results in symptoms akin to those of a heart attack, including chest pain, shortness of breath and arm aches.
The condition is also commonly known as "broken heart syndrome" because it can be caused by an emotionally stressful event, such as the death of a loved one or a divorce, breakup or physical separation from a loved one." LiveScience
