Study Notes

Hypertension Overview

1.28 billion adults worldwide aged 30-79 years have hypertension; about 50% are unaware.
Known as the "silent killer," hypertension can lead to premature death from myocardial infarction (MI), heart failure (HF), cerebrovascular accidents (CVA), and renal disease.

Definition and Measurement

Hypertension is defined by the ACC/AHA as systolic blood pressure (SBP) > 130 mm Hg or diastolic blood pressure (DBP) > 80 mm Hg based on two separate measurements.

Blood Pressure Regulation

Blood Pressure (BP) = Cardiac Output (CO) x Peripheral Vascular Resistance (PVR).
CO is defined as Heart Rate (HR) x Stroke Volume (SV), influenced by CNS, hormones, and ions.

Risk Factors for Hypertension

Primary/Essential Hypertension (90-95% of cases): Cause unknown, associated with increased SNS activity, altered RAAS, sodium retention, insulin resistance, and obesity.
Risk Factor Acronym: RISK FACTOR includes race, sodium or alcohol intake, smoking/stress, potassium levels, family history, age, cholesterol, caffeine intake, obesity, and activity level.
Secondary Hypertension (~5% of cases): Caused by conditions such as heart defects, renal artery stenosis, endocrine disorders, obstructive sleep apnea, pregnancy complications, or medication side effects.

Clinical Manifestations

Often asymptomatic initially but may lead to target organ damage evidenced by changes in vision, chest pain, headache, irritability, epistaxis, and forgetfulness.

Complications of Hypertension

Major complications include angina, MI, HF, stroke, end-organ damage, and aneurysms.

Treatment Guidelines

JNC 8 Guidelines recommend lifestyle modifications for all stages; medication initiated at Stage 1 based on cardiovascular disease risk.
Normal BP management promotes optimal lifestyle habits; stage-based strategies include lifestyle changes alone or combined with medication.

Lifestyle Modifications

Effective strategies include weight loss (5 mm Hg/10 kg), DASH diet, decreased saturated fat, and reduced sodium intake.

Antihypertensive Drugs

Beta-Blockers: Selective (metoprolol, atenolol) and non-selective (propranolol, timolol) block adrenergic receptors.
- Indications: Hypertension, stable angina, tachyarrhythmias, stable HF.
- Side Effects: Bradycardia, exacerbation of HF, rebound hypertension if withdrawn abruptly.
Adjuvant Medications: Include alpha-adrenergic blockers, direct renin inhibitors, and vasodilators.

Hypertensive Crisis

Two types: Urgency (BP > 180/120 mm Hg without organ damage) and Emergency (same BP with organ damage).
Symptoms of emergency include severe headache, vision changes, weakness, and chest pain.
Management involves outpatient urgent care or inpatient ER; BP should be reduced gradually over hours/days to prevent ischemia.

Direct Acting Vasodilators

Prototype: Sodium nitroprusside; acts by relaxing smooth muscle in blood vessels.
Administration: IV with continuous BP monitoring; requires lab monitoring for potential cyanide toxicity.

General Nursing Considerations

Obtain a complete health, medical, and family history; monitor lab tests including electrolytes and lipid panels.
Medication administration should start at the lowest effective dose, utilizing combination therapy if necessary.
Patient education on lifestyle changes and medication adherence is crucial, including the importance of not abruptly stopping medications.
