Study Notes
Definition
- Hypertension, or high blood pressure, is a chronic medical condition where the blood pressure in the arteries is elevated.
Blood Pressure Measurement
- Blood pressure is measured in millimeters of mercury (mmHg) and recorded as two values:
- Systolic Pressure: Pressure during heartbeats (top number).
- Diastolic Pressure: Pressure between heartbeats (bottom number).
- Normal: <120/80 mmHg
- Elevated: 120-129/<80 mmHg
- Hypertension Stage 1: 130-139/80-89 mmHg
- Hypertension Stage 2: ≥140/90 mmHg
Causes
- Primary (Essential) Hypertension: No identifiable cause; develops gradually over years.
- Secondary Hypertension: Caused by underlying conditions, such as:
- Kidney disease
- Hormonal disorders
- Certain medications (e.g., birth control, NSAIDs)
Risk Factors
- Age: Risk increases with age.
- Family History: Genetic predisposition.
- Lifestyle Factors:
- High sodium diet
- Lack of physical activity
- Obesity
- Excessive alcohol consumption
- Smoking
- Chronic conditions: Diabetes, sleep apnea.
Symptoms
- Often asymptomatic; many individuals do not experience symptoms.
- Possible symptoms in severe cases:
- Headaches
- Shortness of breath
- Nosebleeds
- Flushing
- Dizziness
Complications
- Increased risk of:
- Heart disease
- Stroke
- Kidney damage
- Vision loss
- Metabolic syndrome
- Aneurysms
Diagnosis
- Regular blood pressure checks.
- Confirmation through multiple readings over time.
- Additional tests may include blood tests, urinalysis, and ECG.
Management and Treatment
- Lifestyle Modifications:
- Diet: DASH diet (rich in fruits, vegetables, whole grains), reduce sodium intake.
- Exercise: Regular physical activity (30 minutes most days).
- Weight management: Achieve and maintain a healthy weight.
- Limit alcohol intake and quit smoking.
- Medications:
- Diuretics
- ACE inhibitors
- Calcium channel blockers
- Beta-blockers
- Angiotensin II receptor blockers (ARBs)
Monitoring
- Regular check-ups to monitor blood pressure and adjust treatment as necessary.
- Home blood pressure monitoring can be beneficial.
Prevention
- Healthy lifestyle choices: balanced diet, regular exercise, stress management, and avoiding tobacco and excessive alcohol.
Definition of Hypertension
- Chronic medical condition characterized by consistently elevated arterial blood pressure.
- Known as high blood pressure, hypertension increases the risk of heart disease, stroke, and other health complications.
Blood Pressure Measurement
- Blood pressure is expressed in millimeters of mercury (mmHg), a unit reflecting the pressure exerted by blood against artery walls.
- Two key components are recorded:
- Systolic Pressure: Represents the pressure in arteries during heartbeats; recorded as the top number.
- Diastolic Pressure: Reflects the pressure in arteries when the heart is at rest between beats; recorded as the bottom number.
- Normal blood pressure levels indicate healthy cardiovascular function and are critical for overall health.
