Broken Heart Syndrome (BHS) also called stress cardiomyopathy, is triggered by extreme and sudden emotional trauma. Reported triggers have included unexpected news of a death, domestic abuse, armed robbery, and even a surprise party. The condition manifests with symptoms suggesting an acute heart attack (severe pressure-like chest pain, shortness of breath, and a sense of impending doom).
BHS has been written about for many years in Japan (where it is called “octopus trap cardiomyopathy” because of the peculiar shape of the ballooning heart muscle), but until relatively recently it has been poorly recognized in the rest of the world.

Now, researchers at Johns Hopkins have discovered that sudden emotional stress can also result in severe but reversible heart muscle weakness that mimics a classic heart attack. Patients with this condition, called stress cardiomyopathy but known colloquially as “broken heart” syndrome, are often misdiagnosed with a massive heart attack when, indeed, they have suffered from a days-long surge in adrenalin (epinephrine) and other stress hormones that temporarily “stun” the heart.

Tako-tsubo Cardiomyopathy or Syndrome is also known as:
* neurogenic myocardial stunning,
* stress cardiomyopathy
* stress-induced cardiomyopathy,
* transient left ventricular apical ballooning,
* “ampulla” cardiomyopathy
* “broken heart syndrome”.
Root cause of tako-tsubo syndrome: Stress appears to be the underlying root cause in many cases. Because of this, some have investigated an excessive norepinephrine release over the heart muscle. Because this mechanism is not yet proven scientifically to satisfaction, we are a bit helpless for the treatment of this syndrome (we really only have standard support measures that we give to other patients with standard heart failure). There are some attempts to give a calcium channel blocker to prevent coronary spasm, but there is no solid literature on that. Besides, patients often have low blood pressure, prevent us from giving a vasodilator such as a calcium channel blocker. Like everything else: better prevent and recognize tako-tsubo syndrome rather than wait for the full syndrome.
