Phase IV Study to Evaluate the Effects of Statin Monotherapy or Statin / Ezetimibe Combination Therapy on Hepatic Steatosis in Patients With Hyperlipidemia and Nonalcoholic Fatty Liver Disease

To investigate the therapeutic effect of ezetimibe on nonalcoholic fatty liver disease, the effect of rosuvastatin 5mg monotherapy and rosuvastatin 5mg / ezetimibe 10mg combination therapy n patients with hyperlipidemia and fatty liver will be compared and analyzed.

This study included a total of 70 patients (35 per subgroup) for randomized controlled trials with prospective, open label, randomized, single-institution clinical trials.

The drug will be maintained for a total of six months. The primary endpoint is the difference of liver fat change measured by MRI-PDFF in colocalized regions of interest within nine liver segments between two groups.


Eligibility Criteria:
Inclusion Criteria:

* Men or women ages 19 and over, under 80 years of age
* Patients diagnosed with fatty liver by abdominal ultrasonography or liver fibroscan. (In case of patients who were diagnosed fatty liver by liver scan, we will conduct abdominal ultrasonography for screening purposes)
* In the Domestic Dyslipidemia Treatment Guideline, patients with hyperlipidemia A. LDL-C is more than 130mg / dL when there is less than 1 major risk factor B. LDL-C 100 mg / dL or more if there are two or more major risk factors C. High-risk patients with carotid stenosis\> 50%, abdominal aortic aneurysm, and diabetes mellitus had LDL-C\> 70 mg / dL

D. The main risk factors are as follows:

i. smoking ii. Hypertension - systolic blood pressure greater than 140 mmHg or diastolic blood pressure greater than 90 mmHg or antihypertensive iii. Low HDL cholesterol (\<40 mg / dL) iv. Age - Male 45+, Female 55+ v. Family history of early onset coronary artery disease - Parents, siblings with a history of coronary artery disease in men under 55 and women under 65 vi. High HDL cholesterol (60 mg / dL) or more is regarded as a protective factor and one of the total risk factors is reduced

* Even if it does not meet the criteria for hyperlipidemia, it is possible to select the subject when there is evidence of atherosclerosis on the test (carotid ultrasonography etc)
