Impact of canagliflozin on heart stress and outcomes: Pooled insights from CREDENCE and CANVAS.
In individuals with type 2 diabetes with cardio-renal disease but no known heart failure (HF), elevated N-terminal pro-B-type natriuretic peptide (NT-proBNP), a marker of heart stress, signals higher risk of HF and cardio-kidney complications. This analysis assesses canagliflozin impact on heart stress and outcomes using age-adjusted NT-proBNP thresholds from two major trials.
This analysis included 5281 participants from the CANVAS and CREDENCE trials without HF at baseline. NT-proBNP was measured at baseline and year 1, with heart stress defined using age-adjusted NT-proBNP thresholds. Outcomes included a primary composite (end-stage kidney disease, doubling of serum creatinine, kidney or cardiovascular death), kidney composite, HF hospitalization, cardiovascular death, all-cause death, and HF hospitalization or cardiovascular death composite. Multivariable Cox models assessed heart stress, outcomes, and canagliflozin effects. At baseline, 45% of participants had heart stress. Heart stress independently predicted increased risks for all outcomes, with the highest risks in those with persistent or rising NT-proBNP at baseline and year 1. Rising NT-proBNP by year 1 was associated with higher risk as well. Canagliflozin significantly reduced risks in individuals with heart stress, including the primary composite (hazard ratio [HR] 0.72, 95% confidence interval [CI] 0.62-0.84), kidney composite (HR 0.65, 95% CI 0.53-0.79), and HF hospitalization (HR 0.68, 95% CI 0.54-0.85). Benefits were less pronounced in those without heart stress.
Age-adjusted NT-proBNP thresholds effectively predict cardio-kidney events in at-risk type 2 diabetes individuals without HF. Canagliflozin offers strong cardiovascular and kidney protection, with the greatest benefits in those with heart stress, emphasizing the need for early identification and intervention.
