Study Notes
Definition of Hypertension
- Hypertension, also known as high blood pressure, is a chronic medical condition where the blood pressure in the arteries is persistently elevated.
Blood Pressure Measurement
- Blood pressure is measured in millimeters of mercury (mmHg) and is reported using two numbers:
- Systolic (top number): Pressure during heartbeats.
- Diastolic (bottom number): Pressure between heartbeats.
Classification
- Normal: <120/80 mmHg
- Elevated: 120-129/<80 mmHg
- Hypertension Stage 1: 130-139/80-89 mmHg
- Hypertension Stage 2: ≥140/90 mmHg
- Hypertensive Crisis: >180/>120 mmHg
Causes
- Primary Hypertension: No identifiable cause; often related to genetics and lifestyle factors.
- Secondary Hypertension: Caused by underlying conditions such as:
- Kidney disease
- Hormonal disorders
- Certain medications
- Alcohol or substance abuse
Risk Factors
- Age: Risk increases with age.
- Family History: Genetic predisposition.
- Lifestyle Factors:
- Obesity
- Sedentary lifestyle
- High sodium diet
- Excessive alcohol intake
- Smoking
- Chronic conditions: Diabetes, high cholesterol.
Symptoms
- Often asymptomatic; may be called the "silent killer."
- Possible symptoms in severe cases:
- Headaches
- Shortness of breath
- Nosebleeds
- Flushing
Complications
- Heart disease
- Stroke
- Kidney damage
- Vision loss
- Aneurysm
- Metabolic syndrome
Diagnosis
- Regular blood pressure monitoring.
- Confirmatory measurements on multiple occasions.
- Assessment of risk factors and possible underlying conditions.
Treatment
- Lifestyle Modifications:
- Healthy diet (DASH diet)
- Regular physical activity
- Weight management
- Limiting alcohol intake
- Smoking cessation
- Medications:
- Diuretics
- ACE inhibitors
- Angiotensin II receptor blockers (ARBs)
- Calcium channel blockers
- Beta-blockers
Management and Prevention
- Regular health check-ups.
- Education on blood pressure management.
- Monitoring home blood pressure.
- Stress management techniques.
Definition of Hypertension
- Chronic condition characterized by persistently elevated blood pressure in arteries.
Blood Pressure Measurement
- Measured in millimeters of mercury (mmHg).
- Systolic pressure indicates the pressure during heartbeats.
- Diastolic pressure reflects the pressure between heartbeats.
Classification
- Normal blood pressure is defined as 120 mmHg.
Causes
- Primary Hypertension: No known cause; often genetic or lifestyle-related.
- Secondary Hypertension: Linked to specific underlying conditions such as:
- Kidney disease.
- Hormonal disorders.
- Certain medications.
- Substance abuse including alcohol.
Risk Factors
- Age: Increased risk as one gets older.
- Family History: Genetic predisposition to hypertension.
- Lifestyle Factors:
- Obesity contributes to higher blood pressure.
- Sedentary lifestyle can elevate risk.
- High sodium intake is associated with hypertension.
- Excessive alcohol consumption raises blood pressure.
- Smoking increases overall cardiovascular risk.
- Chronic conditions such as diabetes and high cholesterol can elevate blood pressure.
Symptoms
- Often asymptomatic, hence termed the "silent killer."
- Severe cases may present symptoms like:
- Headaches indicating elevated pressure.
- Shortness of breath as a warning sign.
- Nosebleeds may occur spontaneously.
- Facial flushing can indicate hypertension.
Complications
- High blood pressure can lead to serious health issues such as:
- Heart disease increasing the risk of heart attacks.
- Stroke, which can have debilitating effects.
- Kidney damage leading to chronic kidney disease.
- Vision loss due to eye vessel damage.
- Aneurysm formation in blood vessels.
- Metabolic syndrome, increasing the risk of diabetes and cardiovascular disease.
Diagnosis
- Regular blood pressure monitoring is essential for early detection.
- Confirmatory measurements should be taken on multiple occasions.
- Risk factors and potential underlying conditions should be assessed during diagnosis.
Treatment
- Lifestyle Modifications include:
- Adopting a healthy and balanced diet, such as the DASH diet.
- Engaging in regular physical activity to maintain a healthy weight.
- Limiting alcohol consumption and practicing smoking cessation.
- Medications that may be prescribed include:
- Diuretics to help reduce blood volume.
- ACE inhibitors to relax blood vessels.
- Angiotensin II receptor blockers (ARBs) for similar effects.
- Calcium channel blockers to lower heart rate and dilate blood vessels.
- Beta-blockers to manage heart workload.
Management and Prevention
- Regular health check-ups to monitor blood pressure.
- Education on blood pressure management for at-risk individuals.
- Encouraging home monitoring of blood pressure levels.
- Implementing stress management techniques to reduce overall risks.
