Observational Study to Investigate the Effectiveness of Eprosartan on Pulse Pressure (Teveten_MS)

Study Overview
=================
Brief Summary
-----------------
The study is to identify the effectiveness of Eprosartan on pulse pressure in hypertensive patients with metabolic syndrome -Definition of pulse pressure (PP): Difference between systolic and diastolic blood pressure produced one heart beat.

Detailed Description
-----------------
Primary Objective -To assess the changes of pulse pressure at 12 weeks Secondary Objectives To assess the changes of pulse pressure at 4, 24 weeks To assess the changes of systolic blood pressure and diastolic blood pressure at each visit Percentage of responder rate* at each visit and time to get normalized BP from enrollment Responder rate at last visit To assess IIEF-5 (5-item Version of the International Index of Erectile Function) score at enrollment and 24 weeks (percentage of patients with ED according to IIEF-5, Changes of IIEF-5 domains) Percentage of patients with erectile dysfunction (ED) according to IIEF-5 and changes of PP in subgroup (age 65, body mass index (BMI) 23, diabetes mellitus, dyslipidemia, benign prostate hypertrophy) Analysis of correlation between ED and concomitant disease and concomitant medications in patients who received Eprosartan Score changes of Framingham 10-year Coronary Heart Disease (CHD) risk at 1st visit, 4th visit Percentages of Eprosartan monotherapy and multiple antihypertensive therapies at enrollment and last visit Reason for treatment discontinuation (Inadequate BP control, adverse events, others) Adverse events Responder rate: SBP <140mmHg and DBP <90mmHg (SBP <140mmHg and DBP <85mmHg for patients with diabetes mellitus)

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| To assess the changes of pulse pressure at 12 weeks | Calculating pulse pressure at 3rd(12weeks) visit and it will be presented in descriptive statistics quantity | 12 weeks | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| - changes of pulse pressure at 4, 24 weeks - changes of blood pressure at 4, 12, 24 weeks - Duration to get normalized BP - assess IIEF-5 score - Score changes of Framingham 10-year CHD risk | Calculating pulse pressure at each visit and it will be presented in descriptive statistics quantity Variation of the pulse pressure at each visit will be presented in descriptive statistics quantity and average variation's 95% confidence interval will be calculated Calculating systolic blood pressure and diastolic blood pressure at each visit and it will be presented in descriptive statistics quantity Severity of erectile dysfunction will be presented a contingency table and symmetry testing will be done whether there is a significant difference in the data As sub-analysis, type of study drug, age, BMI, with/without diabetes mellitus, with/without dyslipidemia, with/without benign prostate hypertrophy, type of treatment will be considered For safety analysis, overall incidence rate of adverse event will be presented and frequency and percentage will be presented according to body organs and preferable terminology | 24 weeks |
