Empagliflozin Use in Non-Diabetic Patients Over 55 with Cardiovascular Risk Factors
Non-diabetic patients over 55 years old with at least 2 cardiovascular risk factors should take empagliflozin as it reduces the risk of cardiovascular death and heart failure hospitalization regardless of diabetes status.
Mechanism and Evidence Base
Empagliflozin, a sodium-glucose cotransporter 2 (SGLT2) inhibitor, has demonstrated significant cardiovascular benefits beyond its glucose-lowering effects. The strongest evidence comes from:
- The EMPEROR-Preserved trial showed empagliflozin reduced the combined risk of cardiovascular death or hospitalization for heart failure in patients with preserved ejection fraction, regardless of diabetes status (HR 0.79; 95% CI 0.69-0.90; P<0.001) 1
- The American College of Cardiology and European Society of Cardiology recommend SGLT2 inhibitors for patients with heart failure, with benefits seen regardless of diabetes status 2
Cardiovascular Benefits in High-Risk Populations
Empagliflozin provides several cardiovascular benefits that are particularly relevant for non-diabetic patients with cardiovascular risk factors:
- Reduction in heart failure hospitalization: 35% relative risk reduction (2.7% vs 4.1% in placebo) 3
- Reduction in cardiovascular death: 38% relative risk reduction (3.7% vs 5.9% in placebo) 3
- Reduction in all-cause mortality: 32% relative risk reduction (5.7% vs 8.3% in placebo) 3
- Consistent benefits across the spectrum of heart failure risk: Benefits observed in patients with low-to-average, high, and very high 5-year heart failure risk (HR 0.71,0.52, and 0.55 respectively) 4
Cardiac Remodeling Effects
Empagliflozin has demonstrated favorable effects on cardiac structure:
- Reduces left ventricular end-systolic volume index by 6.0 mL/m² (95% CI, -10.8 to -1.2; P=0.015) 5
- Reduces left ventricular end-diastolic volume index by 8.2 mL/m² (95% CI, -13.7 to -2.6; P=0.0042) 5
- These remodeling effects may explain the mechanism by which empagliflozin reduces heart failure hospitalization and mortality 5
Dosing and Administration
Monitoring and Adverse Effects
Common adverse effects to monitor include:
- Genital mycotic infections (more common with empagliflozin than placebo) 1
- Urinary tract infections (increased risk in patients ≥75 years) 6
- Volume depletion/hypotension (risk increases in patients ≥75 years) 6
- Euglycemic diabetic ketoacidosis (rare but serious) 2
Clinical Application
For non-diabetic patients over 55 years with at least 2 cardiovascular risk factors:
- Assess baseline renal function: Ensure eGFR ≥25 mL/min/1.73 m²
- Start empagliflozin 10 mg daily
- Monitor for:
- Volume status and blood pressure
- Genital and urinary tract infections
- Renal function
Important Caveats
- Benefits appear early (within weeks) after initiation 2
- Continue indefinitely as part of cardiovascular risk management 2
- The FDA label for empagliflozin currently focuses on its use in diabetic patients, but clinical evidence supports its use in non-diabetics with cardiovascular risk factors 6, 1
- Patients should be educated about potential side effects and when to seek medical attention
By implementing empagliflozin in non-diabetic patients over 55 with cardiovascular risk factors, clinicians can significantly reduce the risk of cardiovascular death and heart failure hospitalization in this high-risk population.
