Study Notes
Hypertension Overview
- Defined as blood pressure exceeding 130/80 mmHg.
- Most prevalent primary diagnosis in the U.S., affecting around 60 million individuals.
- Approximately 70% are unaware of their hypertensive condition.
Blood Pressure Classification
- Normal: Systolic < 120 mmHg and Diastolic < 80 mmHg.
- Elevated: Systolic 120-129 mmHg or Diastolic < 80 mmHg; lifestyle changes recommended to mitigate risk.
- Stage I Hypertension: Systolic 130-139 mmHg or Diastolic 80-89 mmHg; requires lifestyle advice, possibly antihypertensive medications.
- Stage 2 Hypertension: Systolic ≥ 140 mmHg or Diastolic ≥ 90 mmHg; retake vitals, consult a medical professional if readings persist.
Risks of Untreated Hypertension
- Increases chances of cardiovascular disease (CVD), kidney damage, and cerebrovascular accident (CVA).
- Each 10 mmHg systolic increase above 160 correlates with a 30% higher risk of CVA.
- Hypertension damages cerebral blood vessels, weakening them and leading to lipid accumulation.
Hypertensive Crisis
- Classified as Systolic > 180 mmHg or Diastolic > 120 mmHg.
- Hypertensive Urgency: Not life-threatening but requires prompt action.
- Hypertensive Emergency: Life-threatening, presents similarly to myocardial infarction or CVA.
Hypertensive Urgency
- Symptoms include moderate to severe headache, anxiety, shortness of breath, tinnitus, edema, and epistaxis if BP > 180/110.
- Treatment includes seating the patient upright, checking BP in 5 minutes, seeking immediate medical consultation, and monitoring BP every 5 minutes.
Hypertensive Emergency
- Symptoms involve sudden BP spikes (often around 180/110 to 220/140), dyspnea, chest pain, dysarthria, weakness, along with potential altered consciousness, visual loss, or seizures.
- Treatment involves addressing end organ damage and secondary hypertension, including basic life support, monitoring vitals, and administering oxygen.
Orthostatic Hypotension
- Characterized by a sudden drop in BP due to position change (e.g., from supine to sitting or standing), potentially causing dizziness or loss of consciousness.
- Common causes include prolonged supine positioning, medical conditions, and certain medications.
Symptoms and Treatment
- Symptoms of orthostatic hypotension include dimming vision, decreased hearing, and lightheadedness.
- Treatment involves positioning the patient supine with feet elevated, assessing airway, administering oxygen, and monitoring vital signs. If conditions do not improve, emergency services should be contacted.
