Insights

A high prevalence of uncontrolled hypertension (67.2%) was observed in Lupane, Zimbabwe. Obesity and adding salt to food were significant risk factors, while medication adherence and health education were protective.

Area of Science:

  • Cardiology
  • Public Health
  • Epidemiology

Background:

  • Hypertension control remains a significant public health challenge globally.
  • A previous review at Lupane District Hospital indicated over half of patients had uncontrolled hypertension.
  • This study investigated the prevalence and associated factors of uncontrolled hypertension among treated patients.

Purpose of the Study:

  • To determine the prevalence of uncontrolled hypertension in patients on treatment at Lupane District Hospital.
  • To identify risk factors and protective factors associated with uncontrolled hypertension in this population.

Main Methods:

  • An analytical cross-sectional study was conducted with 354 hypertensive patients on treatment.
  • Data on risk factors were collected using an interviewer-administered WHO-adapted questionnaire.
  • Blood pressure and anthropometric measurements were taken according to WHO guidelines.

Main Results:

  • The prevalence of uncontrolled hypertension was 67.2% (mean BP: 151.0/92.6 mmHg).
  • Obesity (AOR 3.28) and adding salt to food (AOR 2.77) were independent risk factors.
  • Medication compliance (AOR 0.34) and prior health education (AOR 0.49) were protective.

Conclusions:

  • A high prevalence of uncontrolled hypertension exists in Lupane, Zimbabwe, even among patients on medication.
  • Interventions targeting patient behavior, healthcare provider practices, and the health system are crucial for improving hypertension management.
  • Further research and targeted public health initiatives are needed to address this critical issue.

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 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...

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...

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 V: Nursing Management01:23

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.
