Insights

People living with HIV and hypertension show better knowledge of hypertension than HIV, but poor adherence to blood pressure medication. This highlights a need for improved management of comorbidities in HIV patients.

Area of Science:

  • Medical Science
  • Public Health
  • Epidemiology

Background:

  • Increasing prevalence of age-related diseases like hypertension among people living with HIV (PLWHV).
  • Need to assess knowledge, medication adherence, and clinical outcomes in PLWHV with hypertension.

Purpose of the Study:

  • To evaluate knowledge of HIV and hypertension among PLWHV.
  • To assess adherence to prescribed antiretroviral and antihypertensive medications.
  • To determine clinical outcomes, including blood pressure control and viral load, in this population.

Main Methods:

  • Utilized Patient's HIV Knowledge Questionnaire (PHKQ), Hypertension Knowledge-Level Scale (HK-LS), and Adherence to Refills and Medication Scale (ARMS).
  • Administered questionnaires to 220 eligible patients at a Nigerian hospital's HIV clinic.
  • Collected demographic and clinical data, including viral load and blood pressure readings.

Main Results:

  • Participants demonstrated higher hypertension knowledge (63.6%) than HIV knowledge (33.3%).
  • Adherence to antiretroviral medications (100%) was superior to antihypertensive medications (89.3%).
  • Only 56.1% of participants with viral load data had undetectable levels; merely 2.0% achieved controlled blood pressure (<140/90 mmHg).

Conclusions:

  • Despite superior hypertension knowledge, adherence to antihypertensive drugs and blood pressure control remain suboptimal.
  • Emphasizes the necessity for enhanced HIV education and focused management of comorbidities in people living with HIV.
  • Highlights a critical gap in managing hypertension among PLWHV, necessitating targeted interventions.

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.

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 II: Pathophysiology

Hypertension is a chronic condition in which the blood's force against artery walls is excessively high, posing risks such as heart disease. The condition's underlying mechanisms involve complex interactions among the cardiovascular, kidney, and autonomic nervous systems.Renin-Angiotensin-Aldosterone System (RAAS): This system significantly influences blood pressure regulation. When blood pressure decreases, the kidneys secrete renin. This enzyme transforms angiotensinogen, a plasma protein,...

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 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 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...
