Overview

This study will be conducted at six medical institutions in Taiwan, recruiting patients who visit neurology outpatient clinics or are hospitalized within 30 days after an ischemic stroke.

Participants will be randomly assigned to either the experimental group (moderate-intensity statin plus ezetimibe) or the control group (moderate- or high-intensity statin).

Research assistants will screen patients aged 40 or older who have had an ischemic stroke or transient ischemic attack within 30 days, have atherosclerosis, and have LDL-C levels ≥100 mg/dL. Eligible cases will be reviewed by the attending physician. With physician approval, patients will be invited to join the study, and those who agree and sign informed consent will be enrolled.

Exclusion Criteria:

• (1) end stage renal disease because there is no clear benefit of LDL-C lowering therapy in these patients; (2) history of statin intolerance; (3) history of ezetimibe intolerance; or (4) ALT \> 100 U/L.(5) Statins were regularly used before stroke. (6) Ezetimibe was used before stroke.
