Study Notes
Blood Pressure and Hypertension
- Primary determinant of blood pressure: cardiac output and peripheral resistance.
- Key regulators in hypertension: sympathetic nervous system (SNS) and Renin-Angiotensin-Aldosterone System (RAAS).
- Essential hypertension accounts for 90% of hypertension cases.
Symptoms and Consequences
- Typical symptoms of hypertension include dizziness and occipital headaches.
- Uncontrolled hypertension can lead to serious vascular consequences such as heart failure, renal failure, and stroke.
- Blood pressure classification: 160/95 mmHg is categorized as Stage 2 hypertension.
Cardiovascular Impact
- One of the main adverse effects of hypertension is myocardial infarction (MI).
- Hypertensive urgency is defined as a blood pressure reading of 180/110 mmHg.
Lifestyle Management
- Recommended lifestyle modification for hypertension management: reduced sodium intake.
Treatment and Medications
- First-line treatment for hypertension commonly involves ACE inhibitors.
- Common adverse effect of ACE inhibitors: dry cough.
- ARBs (Angiotensin Receptor Blockers) should be avoided in pregnancy.
- ACE inhibitors block the conversion of angiotensin I to angiotensin II.
Risk Factors and Monitoring
- Non-modifiable risk factor for hypertension: age.
- ARBs act by blocking angiotensin II receptors.
- Important monitoring parameters for patients on ACE inhibitors: serum potassium and creatinine.
Long-term Consequences
- Potential consequences of untreated hypertension include stroke.
- Beta-blockers are commonly used antihypertensive agents in patients with heart failure.
- Ankle edema is a common side effect associated with calcium channel blockers.
Additional Notes
- RAAS increases blood pressure by promoting vasoconstriction and sodium/water retention.
- Symptoms of hypertension may also include palpitations, blurred vision, epistaxis, and signs of end-organ damage.
- Regular blood pressure monitoring is crucial for assessing treatment efficacy and preventing complications.
