Mechanical complications of acute myocardial infarction, such as septal or papillary muscle rupture, are associated with high mortality.
Answers are grounded in this paper and cite their sources.
Mechanical complications retain high mortality despite arrhythmia reductions; leaves open optimal prevention and intervention strategies.
THE GREATER availability of well-equipped and well-staffed coro- nary care units, death from arrhythmias complicating myocardial infarction has be- come less common.' This has been a result of improved methods of patient monitoring, earlier diagnosis of arrhythmias, and prompt treatment.2 3 Death from myocardial infarc- tion at present is more commonly a result of cardiogenic shock or refractory cardiac fail- ure." 3-5 The mechanical complications of myocardial infarction, including rupture of the interventricular septum, papillary muscle rup- ture, and acute left ventricular aneurysm, although uncommon, are associated wih a high mortality rate.
