Insights

Uncontrolled systolic and diastolic blood pressure (BP) in Korean adults with high medication adherence is linked to various factors. Older age, female sex, and diabetes are associated with uncontrolled systolic BP, while heavy alcohol consumption impacts both.

Area of Science:

  • Cardiology
  • Public Health
  • Epidemiology

Background:

  • Uncontrolled blood pressure (BP) remains prevalent despite antihypertensive medication.
  • High medication adherence is crucial for effective hypertension management.
  • Understanding factors associated with uncontrolled BP is vital for targeted interventions.

Purpose of the Study:

  • To investigate factors associated with uncontrolled systolic blood pressure (SBP) and diastolic blood pressure (DBP) separately.
  • To analyze these factors in Korean hypertensive patients with high medication adherence.
  • To identify specific predictors for SBP and DBP control in this population.

Main Methods:

  • A population-based cross-sectional study using data from the Korea National Health and Nutrition Examination Survey (2013-2015).
  • Inclusion of 3,236 hypertensive patients with high medication adherence (daily antihypertensive use).
  • Logistic regression analysis to determine associations between uncontrolled SBP (≥140 mmHg) or DBP (≥90 mmHg) and various demographic, lifestyle, and clinical factors.

Main Results:

  • Prevalence of uncontrolled SBP was 23.3% and uncontrolled DBP was 9.0%.
  • Uncontrolled SBP associated with older age, female sex, blue-collar/no work, spouse presence, short sleep, heavy alcohol use, longer hypertension duration, diabetes, stroke, and missed medication; negatively associated with high stress.
  • Uncontrolled DBP associated with heavy alcohol use; negatively associated with older age, blue-collar/no work, and diabetes.

Conclusions:

  • Various factors are associated with uncontrolled SBP and DBP in Korean adults with treated hypertension, even with high medication adherence.
  • Distinct factors influence uncontrolled systolic and diastolic blood pressure.
  • Separate analysis of SBP and DBP is valuable for understanding hypertension control factors.

Hypertension IV: Drug Therapy and Lifestyle Modifications

Multiple classes of antihypertensive medications are employed in treating hypertension. The most commonly recommended first-line treatments include:Thiazide Diuretics, such as chlorthalidone, increase sodium and water excretion from the body, reducing blood volume and blood pressure.Angiotensin-converting enzyme inhibitors, like lisinopril, block the conversion of angiotensin I to II, a potent vasoconstrictor lowering blood pressure.Angiotensin II Receptor Blockers (ARBs) prevent angiotensin II...

Hypertension III: Clinical Manifestations and Diagnostic Studies

Hypertension is asymptomatic and also referred to as the "silent killer" until it progresses to a severe stage or causes target organ disease. Patients may experience symptoms stemming from the strain on blood vessels and tissues in various organs or the heart's increased workload.Physical exams might show no abnormalities other than high blood pressure. Signs of vascular damage, when present, correspond to the organs supplied by the affected vessels, leading to target organ damage. For...

Hypertension and Regulation of Blood Pressure01:18

Hypertension and Regulation of Blood Pressure

Hypertension, the most common cardiovascular disease, is diagnosed through repeated measurements of elevated blood pressure. Its risks, including damage to the kidney, heart, and brain, are directly proportional to blood pressure levels. Starting from 115/75 mm Hg, the risk of cardiovascular disease doubles with each increment of 20/10 mm Hg. The diagnosis relies on blood pressure measurements, not on patient symptoms, as hypertension is often asymptomatic until end-organ damage is imminent or...

Errors occurring during blood pressure monitoring

Blood pressure monitoring is a crucial clinical procedure in diagnosing and managing various cardiovascular conditions. Despite its significance, the accuracy of blood pressure measurements can be compromised by multiple factors, potentially leading to either falsely high or low readings. These inaccuracies are critical as they can significantly impact patient care. So, it is vital to understand these challenges deeply and adopt strategic approaches to minimize errors.

Hypertension I: Introduction01:28

Hypertension I: Introduction

Hypertension is a widespread, long-term medical condition where blood pressure in the arteries remains elevated. It is characterized by systolic blood pressure readings of 130 mm Hg or above or diastolic blood pressure (DBP) readings of 80 mm Hg or higher. Unmanaged hypertension poses significant health risks, making the distinction between primary (or essential) hypertension and secondary hypertension crucial, as their management and implications vary.Primary HypertensionPrimary hypertension,...

Hypertension V: Nursing Management

The nursing management of hypertension involves accurately assessing symptoms, making a comprehensive nursing diagnosis, collaborating with patients to set goals, and implementing targeted interventions to mitigate the condition's impact and improve patient well-being.Comprehensive AssessmentThe initial step in nursing care for hypertension involves a thorough patient assessment. It includes evaluating symptoms such as headaches, dizziness, blurred vision, and previous hypertension episodes.
