To evaluate risk factors in association with the duration of hospitalization, we found variables which lengthened hospitalization span including; age over 60 years (HR= 0.42 P= 0.002), hypercholesterolemia (HR= 2.19 P= 0.031), Angiotensin-converting enzyme (ACE) Inhibitors consumption (HR= 1.87 P= 0.022), and type of infarction (non-lacunar) (HR= 0.51 P= 0.026). Here, ACE is linked to infarction.
