What are the target blood pressure ranges for various cardiology conditions, including hypertension, heart failure, coronary artery disease (CAD), chronic kidney disease (CKD), and atrial fibrillation (AF)?

Target Blood Pressure Ranges for Various Cardiology Conditions

The recommended blood pressure targets vary by specific cardiovascular condition, with general targets of <130/80 mmHg for most patients with hypertension, but specific adjustments needed based on comorbidities and individual risk factors. 1

General Hypertension Management

Classification and Initial Targets

• Normal BP: <130/85 mmHg
• Hypertension: ≥140/90 mmHg 1
• Initial target for all hypertensive patients: <140/90 mmHg
• Optimal target if tolerated: <130/80 mmHg 1

Treatment Algorithm

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

   • Start lifestyle interventions
   • Start drug treatment immediately in high-risk patients (CVD, CKD, diabetes, organ damage)
   • For low-risk patients: 3-6 months of lifestyle intervention before drug therapy

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

   • Start lifestyle interventions
   • Start drug treatment immediately 1

Specific Cardiovascular Conditions

Chronic Kidney Disease (CKD)

• General target: 130-139 mmHg systolic 1
• For moderate-to-severe CKD with eGFR >30 mL/min/1.73 m²: 120-129 mmHg systolic 1
• For patients with albuminuria: <130/80 mmHg 1, 2
• For patients with low albuminuria: <140/90 mmHg 1, 2

Heart Failure

1. Heart Failure with Reduced Ejection Fraction (HFrEF):

   • Target: <130/80 mmHg 1
   • Treatment should include ACE inhibitor/ARB, beta-blocker, diuretic, and/or mineralocorticoid receptor antagonist

2. Heart Failure with Preserved Ejection Fraction (HFpEF):

   • Target: <130/80 mmHg 1
   • Consider SGLT2 inhibitors to improve outcomes

Coronary Artery Disease (CAD)

• Target: <130/80 mmHg 1
• Caution: Avoid diastolic BP <70 mmHg due to risk of coronary hypoperfusion 1

Stroke and TIA

• Target: 120-130 mmHg systolic 1
• For patients with history of stroke/TIA: <130/80 mmHg 1

Atrial Fibrillation

• Target: <130/80 mmHg (same as general hypertension target) 1
• Focus on BP control to reduce risk of stroke and heart failure

Diabetes

• Target: <130/80 mmHg 1
• For older patients (≥65 years): 130-139 mmHg systolic 1
• Lower limit: Not <120 mmHg systolic 1

Special Populations

Older Adults (≥65 years)

• Target: 130-139 mmHg systolic 1
• For frail elderly: Individualize targets based on tolerability
• Caution: Monitor for orthostatic hypotension and adverse effects

Pregnancy

• For gestational hypertension or pre-existing hypertension:
  • Target: <140/90 mmHg but not <80 mmHg diastolic 1
  • Emergency threshold: ≥170/110 mmHg (requires hospitalization) 1

Monitoring and Follow-up

• Initial follow-up: Within first 2 months after starting therapy
• After reaching target: Every 3-6 months
• Target achievement timeframe: Within 3 months of initiating therapy 1

Common Pitfalls and Caveats

1. Measurement technique matters:

   • Automated office BP readings are typically 10-15 mmHg lower than conventional office readings 3
   • Use validated devices with appropriate cuff size 1

2. Avoid excessive BP lowering:

   • Diastolic BP should generally not be <70 mmHg, especially in CAD patients 1
   • Risk of falls and orthostatic hypotension increases with aggressive treatment in elderly

3. Standardized measurement:

   • Different guidelines base recommendations on different measurement techniques
   • KDIGO's target of <120 mmHg is based on standardized measurements, not routine office readings 1

4. Resistant hypertension management:

   • Add spironolactone to existing treatment
   • Consider sodium restriction
   • Rule out secondary causes of hypertension 1

The evidence strongly supports that achieving these target BP ranges reduces cardiovascular morbidity and mortality across various conditions, with the most recent guidelines trending toward lower targets than previously recommended.
