Race in Heart Failure: A Pooled Participant-Level Analysis of the Global PARADIGM-HF and PARAGON-HF Trials.
Race in Heart Failure: A Pooled Participant-Level Analysis of the Global PARADIGM-HF and PARAGON-HF Trials. JACC. Heart failure Lu, H., Claggett, B. L., Packer, M., Pabon, M. A., Pfeffer, M. A., Lewis, E. F., Lam, C. S., Rouleau, J., Zile, M. R., Lefkowitz, M., Desai, A. S., Jhund, P. S., McMurray, J. J., Solomon, S. D., Vaduganathan, M. 2024Abstract
Mechanisms of disease pathobiology, prognosis, and potentially treatment responses might vary by race in patients with heart failure (HF).The authors aimed to examine the safety and efficacy of sacubitril/valsartan among patients with HF by self-reported race.PARADIGM-HF (Prospective Comparison of ARNI with ACEI to Determine Impact on Global Mortality and Morbidity in Heart Failure) and PARAGON-HF (Prospective Comparison of ARNI with ARB Global Outcomes in HF With Preserved Ejection Fraction) were global, randomized clinical trials testing sacubitril/valsartan against a renin-angiotensin system inhibitor ([RASi], enalapril or valsartan, respectively) in patients with HF and left ventricular ejection fraction =40% (PARADIGM-HF) or left ventricular ejection fraction =45% (PARAGON-HF). Patients with self-reported race were categorized as White, Asian, or Black. We assessed the composite of first HF hospitalization or cardiovascular death, its components, and angioedema across races.Among 12,097 participants, 9,451 (78.1%) were White, 2,116 (17.5%) were Asian, and 530 (4.4%) were Black. Over a median follow-up of 2.5 years, Black (adjusted HR: 1.68; 95% CI: 1.42-1.98) and Asian patients (adjusted HR: 1.32; 95% CI: 1.18-1.47) experienced higher risks of the primary outcome compared with White patients. Treatment effects of sacubitril/valsartan vs RASi on the primary endpoint were consistent among White (HR: 0.84; 95% CI: 0.77-0.91), Asian (HR: 0.92; 95% CI: 0.78-1.10), and Black patients (HR: 0.79; 95% CI: 0.58-1.07; Pinteraction = 0.58). Rates of severe angioedema were higher with sacubitril/valsartan vs RASi (White: 0.2% vs 0.1%; Black: 1.5% vs 0.0%; Asian: 0.1% vs 0.1%).In a pooled experience of 2 global trials, Black and Asian patients exhibited a higher risk of cardiovascular events than White patients. The benefits of sacubitril/valsartan were consistent across races. Risks of severe angioedema were low but numerically higher with sacubitril/valsartan.
