<P> Complications may occur immediately following the myocardial infarction or may take time to develop . Disturbances of heart rhythms , including atrial fibrillation , ventricular tachycardia and fibrillation and heart block can arise as a result of ischemia , cardiac scarring , and infarct location . Stroke is also a risk , either as a result of clots transmitted from the heart during PCI , as a result of bleeding following anticoagulation , or as a result of disturbances in the heart 's ability to pump effectively as a result of the infarction . Regurgitation of blood through the mitral valve is possible , particularly if the infarction causes dysfunction of the papillary muscle . Cardiogenic shock as a result of the heart being unable to adequately pump blood may develop , dependent on infarct size , and is most likely to occur within the days following an acute myocardial infarction . Cardiogenic shock is the largest cause of in - hospital mortality . Rupture of the ventricular dividing wall or left ventricular wall may occur within the initial weeks . Dressler 's syndrome , a reaction following larger infarcts and a cause of pericarditis is also possible . </P>
