Hypertension

Hypertension (high blood pressure) damages arteries and vital organs over time, leading to stroke, heart attack, kidney disease, and vision loss. Because it rarely causes symptoms, regular monitoring and proactive management are essential.

Blood Pressure Categories (ACC/AHA)

• Normal: < 120 / < 80 mmHg
• Elevated: 120–129 / < 80 mmHg
• Stage 1: 130–139 / 80–89 mmHg
• Stage 2: ≥ 140 / ≥ 90 mmHg
• Hypertensive crisis: ≥ 180 / ≥ 120 mmHg (seek emergency care if symptomatic)

Causes & Risk Factors

• Genetics and family history
• Aging, male sex (until menopause), African ancestry
• Obesity, sedentary lifestyle, high-sodium diet
• Excess alcohol, smoking, chronic stress
• Sleep apnea, diabetes, kidney disease, thyroid disorders
• Certain medications (NSAIDs, decongestants, oral contraceptives)

Symptoms

Most people have no symptoms. Severe or sudden hypertension may cause:

• Headache, visual changes, dizziness
• Shortness of breath, chest pain, nosebleeds
• Neurologic deficits (emergency)

Diagnosis & Monitoring

• Confirm elevated readings on at least two occasions.
• Use validated home BP devices; average multiple readings and monitor at the same time daily.
• Ambulatory BP monitoring helps detect masked or white-coat hypertension.
• Labs: BMP, fasting glucose, lipid panel, TSH, urinalysis, albumin-creatinine ratio.
• ECG or echocardiogram to assess heart muscle changes.

Treatment & Management

Lifestyle First

• Adopt DASH or Mediterranean diet rich in vegetables, fruits, whole grains, lean protein.
• Limit sodium to < 1,500–2,000 mg/day; increase potassium unless contraindicated.
• 150 minutes/week aerobic exercise + strength training.
• Maintain healthy weight (5–10% loss can significantly lower BP).
• Limit alcohol (≤1 drink/day women, ≤2 for men), avoid smoking, manage stress, sleep 7–8 hours.

Medications

• Thiazide diuretics, ACE inhibitors, ARBs, or calcium channel blockers are first-line.
• Combine agents when BP > 20/10 above goal or in stage 2 disease.
• Beta-blockers for specific indications (CAD, arrhythmias, heart failure).
• Mineralocorticoid receptor antagonists for resistant hypertension.
• Evaluate secondary causes if uncontrolled on ≥3 drugs.

Targets

• General: < 130/80 mmHg for most adults.
• Individualize goals for older adults, CKD, diabetes, or frailty.

Living with Hypertension

• Track BP, weight, pulse, medications, mood, and stress in a log.
• Refill prescriptions on time; discuss side effects promptly.
• Practice relaxation techniques (breathing exercises, mindfulness).
• Schedule routine dental and eye exams—hypertension affects gums and retina.

Complications

• Left ventricular hypertrophy, heart failure, coronary artery disease
• Stroke or transient ischemic attack
• Chronic kidney disease, peripheral arterial disease
• Retinopathy and vision loss

Research & Future Directions

Digital therapeutics, AI-guided drug titration, renal denervation, and wearable BP sensors are transforming hypertension care.

Experimental & Emerging Treatments

• Renal Denervation: Catheter-based ablation of renal nerves shows durable BP reductions in resistant hypertension.
• Baroreflex Activation Therapy: Implantable devices stimulate carotid baroreceptors to lower BP autonomically.
• Endovascular Arteriovenous Couplers: Create controlled shunts to reduce peripheral resistance; still investigational.
• AI-Integrated Wearables: Cuffless sensors combined with adaptive coaching deliver “precision antihypertension” programs in trials.
