| Trial | Population | Clinical HF event reduction | Subclinical HF markers | Structural remodeling signals | Effects on renal outcomes | Key clinical message |
|---|---|---|---|---|---|---|
| EMPA-REG OUTCOME trial [17] (2015) | T2DM+established ASCVD (n=7,020) | ↓HF hospitalizations (HR, 0.65; 35% RRR) | Not assessed | Not assessed | Reduced incident/worsening nephropathy and progression to advanced renal disease | First robust evidence that SGLT2 inhibitor reduces HF events |
| CANVAS Program [18] (2017) | T2DM+high CV risk (n=10,142) | ↓HF hospitalizations (HR, 0.67; 33%–35% RRR) | Not assessed | Not assessed | Reduced composite renal outcome and slowed eGFR decline | Reinforced HF risk reduction across high-risk T2DM |
| DECLARE–TIMI 58 trial [19] (2019) | T2DM; majority without ASCVD (n=17,160) | ↓HF hospitalizations (HR, 0.73; 27%–37% RRR) | Not assessed | Not assessed | Reduced renal composite and slowed eGFR decline | Demonstrated HF prevention in a largely primary-prevention cohort |
| DAPA-CKD trial [20] (2020) | CKD (n=4,304) | ↓HF hospitalizations (HR, 0.71; 29% RRR) | Not assessed | Not assessed | 39% Reduction in renal composite; slower eGFR decline | Extends HF risk reduction to high-risk CKD, supporting early cardiorenal intervention |
| SCORED trial [21] (2021) | T2DM+CKD (higher HF risk) (n=10,500) | ↓HF hospitalizations (HR, 0.67; 33% RRR) | Not assessed | Not assessed | ≈30% Reduction in renal composite; slower eGFR decline | Consistent HF event reduction in patients with advanced CKD, suggesting that upstream cardiorenal modulation may attenuate progression toward overt HF phenotypes within the CKM continuum |
