What is the step-by-step treatment plan for hypertension in India?

Step-by-Step Hypertension Treatment Plan in India

For patients in India, the recommended hypertension treatment approach should follow a structured algorithm starting with proper diagnosis followed by lifestyle modifications and appropriate pharmacological therapy based on ethnicity and risk factors.

Diagnosis

• Use validated BP measuring device with appropriate cuff size for accurate measurement 1
• Confirm hypertension with repeated office BP readings ≥140/90 mmHg, ideally supported by home BP ≥135/85 mmHg or 24h ambulatory BP ≥130/80 mmHg 1
• At first visit, measure BP in both arms simultaneously; if consistent difference exists, use the arm with higher BP for subsequent measurements 1

Initial Assessment

• Evaluate for hypertension-mediated organ damage (HMOD) and cardiovascular risk factors 1
• Check for comorbidities that may influence treatment choices (CAD, stroke, heart failure, CKD, COPD) 1
• Consider additional tests if secondary hypertension is suspected 1

Step 1: Lifestyle Modifications (for all patients)

• Salt restriction (particularly important for South Asian populations) 1, 2
• Increased intake of vegetables and fruits (potassium intake) 1, 3
• Weight management for those with elevated BMI 1, 2
• Regular physical exercise 2, 4
• Alcohol reduction or avoidance 1, 2
• Smoking cessation 2
• Stress management techniques including yoga and meditation 2, 4
• DASH diet or modifications appropriate for Indian cuisine 3

Step 2: Pharmacological Therapy

For Grade 1 Hypertension (140-159/90-99 mmHg):

• For high-risk patients (with CVD, CKD, diabetes, organ damage, or aged 50-80 years): Start drug treatment immediately along with lifestyle modifications 1, 5
• For low-to-moderate risk patients: Trial of lifestyle modifications for 3-6 months, then initiate pharmacotherapy if BP remains elevated 1, 5

For Grade 2 Hypertension (≥160/100 mmHg):

• Start drug treatment immediately along with lifestyle modifications 1

First-line Pharmacological Options:

For South Asian patients in India:

• Standard treatment as indicated in international guidelines is recommended 1
• First-line therapy options:
  • Non-black patients: Start with low-dose ACE inhibitor/ARB 1
  • Consider ARBs (like losartan) as they have proven efficacy in hypertension and additional benefits in patients with left ventricular hypertrophy or diabetic nephropathy 6

Step-by-Step Drug Therapy Escalation:

For non-black patients:

1. Start with low-dose ACE inhibitor/ARB 1
2. Increase to full dose if needed 1
3. Add calcium channel blocker (CCB) 1
4. Add thiazide/thiazide-like diuretic 1
5. If BP still uncontrolled, add spironolactone or, if not tolerated, consider amiloride, doxazosin, eplerenone, clonidine, or beta-blocker 1

Step 3: Monitoring and Follow-up

• Target: Reduce BP to <130/80 mmHg (individualize for elderly based on frailty) 1
• Monitor BP control regularly with goal to achieve target within 3 months 1, 5
• Check adherence to both medications and lifestyle modifications 1
• Assess for medication side effects 1
• If BP remains uncontrolled despite optimal therapy, refer to specialist with hypertension expertise 1

Special Considerations for India

• Utilize resources from the India Hypertension Control Initiative (IHCI) program which provides systematic implementation across various states 7
• Consider using the Simple mobile application (developed by Resolve to Save Lives) for analysis and storage of patient data to ensure proper record keeping and follow-ups 7
• Emphasize combined approach of medications and lifestyle modifications as the gold standard treatment 7
• Ensure regular supply and availability of essential antihypertensive medications 7

Hypertension with Comorbidities

• Coronary Artery Disease: Use RAS blockers, beta-blockers with or without CCBs; target BP <130/80 mmHg (<140/80 in elderly) 1
• Previous Stroke: Use RAS blockers, CCBs, and diuretics; target BP <130/80 mmHg (<140/80 in elderly) 1
• Heart Failure: Use RAS blockers, beta-blockers, and mineralocorticoid receptor antagonists; target BP <130/80 mmHg but >120/70 mmHg 1
• Chronic Kidney Disease: Use RAS inhibitors as first-line drugs; add CCBs and diuretics (loop diuretics if eGFR <30 ml/min/1.73m²); target BP <130/80 mmHg (<140/80 in elderly) 1

Remember that hypertension control is part of comprehensive cardiovascular risk management and should include appropriate management of other risk factors such as diabetes and dyslipidemia 6.
