Myocardial Rupture

Myo·car·di·al
adj. 
Myo translates to muscle (Ancient Greek: Mus or Mys), while cardia/cardio translates to heart (Ancient Greek: Kardia)

A myocardial rupture is a laceration or the tearing of any part of the heart. It is a quite rare, and usually fatal complication of myocardial infarction (heart attacks).
It accounts for roughly 1/4th of all deaths caused (indirectly) by myocardial infarction.[1]

 Causes
- Myocardial infarction[1]
- Cardiac trauma
- Endocarditis (inflammation of the heart)[3]
- Cardiac tumors
- Infiltrative diseases of the heart[2][3]

Risk groups
- Women <70yo. Note that it affects a large number of women aged <70, whereas it kills a large number of women >70[4] 
- Increasing age[4]
- People with recent myocardial infarction[1][4]

Symptoms
The symptoms are achingly similar to the symptoms present in patients suffering myocardial infarction. Some patients may be relatively asymptomatic.
- Death, possibly.
- Cool, clammy skin
- Intense pain near the heart area
- Shortness of breath
- Heart failure
- Shock
