Study Description
Brief Summary:

Study Objectives The study is to identify prevalence, demography and clinical characteristics of patients with resistant hypertension among hypertensive patients who have been treated in general hospitals in Korea from Jan 2012 to Jun 2012.

  • Diagnosis of resistant hypertension: In case of clinic blood pressure exceeding the boundary of systolic blood pressure at 140mmHg and diastolic blood pressure at 90mmHg (hereinafter refer to as 140/90mmHg) (130/80mmHg for patients with diabetes mellitus or chronic renal disease) despite triple antihypertensive therapy at optimal dose may be diagnosed as resistant hypertension. Antihypertensive medications used include diuretics. Resistant hypertension may also be diagnosed when clinic blood pressure has reached the target value but quadruple or more of antihypertensives are used.
  • Diagnosis of controlled hypertension: Patients whose clinic blood pressure equals to 140/90mmHg (130/80mmHg for patients with diabetes mellitus or chronic renal disease) or less with the administration of antihypertensives at optimal dose may be diagnosed as controlled hypertension.

Detailed Description:

Primary Objective:

Prevalence in patients with resistant hypertension among hypertensive patients who have been treated in Korean general hospitals

Secondary Objectives:

Analysis of correlation in patients with resistant hypertension and patients with controlled hypertension who received triple antihypertensive therapy in terms of demography, clinical characteristics and other factors

  1. Demographic data (age, sex, and body mass index)
  2. Clinical characteristics

    • Vital signs
    • Lifestyles (history of drinking, smoking, and exercise)
    • Family history (hypertension, diabetes mellitus, dyslipidemia, cardiovascular disease, renal/adrenal disease, cerebrovascular disease, and respiratory disease)
    • Concurrent diseases (diabetes mellitus, dyslipidemia, cardiovascular disease, renal/adrenal disease, cerebrovascular disease, respiratory disease, and others)
    • History of antihypertensive therapy (past and present)
    • Medication compliance of antihypertensives
    • Concomitant medications

Outcome Measures

Primary Outcome Measures :
  1. Prevalence of resistant hypertension [ Time Frame: up to 6 months ]
    Prevalence of resistant hypertension will be estimated, and its 95% confidence interval will be calculated. In addition, proportion of controlled hypertensive patients and its 95% confidence interval will be calculated.


Secondary Outcome Measures :
  1. Analysis of correlation in patients with resistant hypertension and patients with controlled hypertension who received triple antihypertensive therapy in terms of demography, clinical characteristics and other factors [ Time Frame: up to 6 months ]
    Clinical characteristics in subjects diagnosed of resistant hypertension and those diagnosed of controlled hypertension will be described in summary.
