Acute<unk><unk>  involving only the free wall of the<unk>  ventricle is a rare event.   More commonly,<unk>  ventricular<unk>  is associated with<unk>  of the inferior wall of the left ventricle, occurring in more than one-third of such cases,         even when a thrombolytic therapy is given. 
One study of 113 patients with a first acute inferior wall<unk>  reported that the presence of preinfarction angina within 72 hours of the<unk>  was associated with a reduction in the incidence of<unk>  ventricular<unk>  (odds ratio 0.2) and combined hypotension and shock (odds ratio 0.1).  This is possibly the result of ischemic preconditioning.
Ninety percent of<unk>  ventricular infarcts result from occlusion of the proximal<unk>  coronary artery, while another 5 to 10 percent arise after occlusion of the left anterior descending artery    
Although more than one-third of cases are clinically silent , the presence of<unk>  ventricular<unk>  often has important implications for both management and prognosis.
