Study Notes
Hypertension Overview
- Approximately 90% of hypertension cases are classified as primary (essential) hypertension.
- The Renin-Angiotensin-Aldosterone System (RAAS) is key for long-term blood pressure regulation.
Kidney Function in Blood Pressure Regulation
- Kidneys regulate blood pressure primarily by managing sodium balance and fluid levels.
Risk Factors for Hypertension
- High sodium intake is a significant risk factor for developing hypertension.
- Age is a non-modifiable risk factor; lifestyle factors like smoking and physical inactivity are modifiable.
Consequences of Untreated Hypertension
- Long-term untreated hypertension can lead to serious conditions, including aneurysms and strokes.
- Hypertension is referred to as a "silent killer" due to its often asymptomatic nature.
Pathophysiology and Related Factors
- Increased peripheral resistance in hypertension is largely due to heightened arterial stiffness.
- The body’s RAAS increases both vasoconstriction and blood volume, contributing to hypertension.
Symptoms and Diagnosis
- Commonly, hypertension may present with no symptoms at all, making it challenging to diagnose early.
- Blood pressure readings are essential for classifying the severity of hypertension.
Heart Failure Mechanism
- Hypertension increases myocardial oxygen demand, which contributes to heart failure.
Treatment and Medications
- First-line treatment for hypertension includes ACE inhibitors.
- ACE inhibitors are associated with a persistent dry cough, leading to the use of angiotensin II receptor blockers (ARBs) for patients seeking alternatives.
Special Considerations in Treatment
- Patients with asthma should avoid beta-blockers due to potential exacerbation of symptoms.
- Regular monitoring of serum potassium and renal function is crucial when prescribing ACE inhibitors.
Management in Special Populations
- Patients with chronic kidney disease (CKD) often receive ACE inhibitors for managing hypertension.
- Thiazide diuretics and calcium channel blockers are preferred for African American patients with hypertension.
Goals of Management
- The primary aim of hypertension management is to prevent complications, notably stroke and myocardial infarction.
- The recommended blood pressure target for patients aligns with guideline recommendations for effective management.
