Study Notes
Overview of Hypertension (HT)
- HT is a chronic disease affecting a wide range of individuals.
- Many patients experience asymptomatic stages, particularly in stage I and stage II HT.
- Signs and symptoms often manifest late, indicating extensive end-organ damage.
Long-Term Management
- Persistent hypertension typically necessitates long-term use of blood pressure (BP) lowering drugs.
- Lifestyle modifications are crucial and can sometimes control hypertension effectively without medication.
- Key lifestyle changes include exercise, healthy diet (low salt intake, caloric restriction), adequate sleep, and stress management.
Consequences of Untreated Hypertension
- Untreated HT can lead to significant damage to the blood vessels, heart, and kidneys.
- Higher BP increases the risk of developing end-organ damage.
- Vascular damage includes accelerated atherosclerosis, which can cause:
- Transient ischemic attacks or strokes (cerebral arteries).
- Angina pectoris and acute coronary syndromes (coronary arteries).
- Chronic kidney disease resulting from renal artery atherosclerosis, potentially leading to dialysis or transplants.
Medications That May Raise Blood Pressure
- Alpha1-agonists (e.g., phenylephrine) commonly found in decongestants.
- High-dose steroids due to mineralocorticoid effects.
- NSAIDs impair vasodilation and sodium excretion by inhibiting prostaglandin production.
- Various drugs like cocaine, amphetamines, certain antidepressants (e.g., Venlafaxine), birth control pills, licorice, and others may also increase BP.
Treatment Approaches
- All patients with BP over 120/80 should consider lifestyle changes or pharmacological therapy based on risk exposure.
- Modifiable risk factors include stress, sedentary lifestyle, and excessive salt or alcohol intake.
- Non-modifiable risk factors include age, gender (higher in males), race (more prevalent in African-Americans), and family history.
Blood Pressure Measurements
- Initial BP assessments should occur in multiple positions (supine, standing, sitting) and should be measured in both arms and one leg.
- The arm showing higher BP readings should be used for future measurements, ensuring proper cuff size is utilized.
- Automated BP monitors can provide 24-hour recordings to assess BP variations, identify dippers and non-dippers, and evaluate medication effectiveness.
Types of Hypertension
- Essential or Primary Hypertension accounts for about 90% of cases.
- Secondary Hypertension can result from multiple factors including renal disease, sleep apnea, drug-induced causes, and several endocrine disorders.
