Study Notes
Hypertension Overview
- Primary (essential) hypertension accounts for approximately 90% of cases.
- The Renin-Angiotensin-Aldosterone System (RAAS) is crucial for long-term blood pressure regulation.
- Kidneys play a primary role in sodium balance and fluid regulation, impacting blood pressure.
Risk Factors for Hypertension
- High sodium intake is a common developmental risk factor.
- Age is a non-modifiable risk factor; others such as smoking, physical inactivity, and a high salt diet are modifiable.
- Long-term untreated hypertension may lead to serious conditions like aneurysm and stroke.
Symptoms and Diagnosis
- Hypertension is often asymptomatic, giving it the title "silent killer."
- Blood pressure readings are essential for classifying hypertension severity.
Hormonal Influence
- Aldosterone is the hormone that primarily increases sodium reabsorption in kidneys, contributing to hypertension.
- The pulse pressure reflects arterial stiffness, a concern in hypertension.
Secondary Hypertension
- Chronic kidney disease is a common contributor to secondary hypertension.
- Increased arterial stiffness contributes to higher peripheral resistance.
Treatment Approaches
- First-line treatment generally involves ACE inhibitors.
- ACE inhibitors are associated with a persistent dry cough; ARBs have fewer side effects.
- Diuretics like thiazides can lead to hypokalemia and are linked to a risk of developing diabetes mellitus.
Monitoring and Precautions
- Patients on ACE inhibitors should have serum potassium and renal function monitored regularly.
- In patients with asthma, beta-blockers should be avoided.
- For hypertensive patients with a history of myocardial infarction, beta-blockers are favored.
Special Considerations
- Preferred treatment for African American patients includes thiazide diuretics and calcium channel blockers.
- The goal of hypertension management is to prevent complications, mainly stroke and myocardial infarction.
Additional Key Points
- Sodium nitroprusside is used in hypertensive emergencies.
- Blood pressure targets should be based on clinical guidelines, generally aiming for below 140/90 mmHg for many patients.
