BACKGROUND: Coronary collateral circulation (CCC) is a key determinant of myocardial viability and prognosis in patients with chronic total occlusion (CTO). The hemoglobin, albumin, lymphocyte, and platelet (HALP) score reflects nutritional status, immune competence, and systemic inflammation. OBJECTIVES: To investigate the association between HALP score and CCC in patients with CTO. METHODS: This retrospective, single-center study included 269 patients with chronic coronary syndrome and angiographically confirmed CTO. Patients were classified according to Rentrop grades and dichotomized into poor CCC (Rentrop 0-1; n=119) and good CCC (Rentrop 2-3; n=150). HALP score, inflammatory markers, atherogenic indices, and angiographic scores were compared between groups. Multivariate logistic regression and receiver operating characteristic (ROC) analyses were performed. A p-value <0.05 was considered statistically significant. RESULTS: HALP score increased significantly across Rentrop grades (p<0.001) and was higher in patients with good CCC than in those with poor CCC (75.52±13.91 vs. 35.10±11.29; p<0.001). In multivariable analysis, HALP score (OR:0.88, 95% CI: 0.83-0.93; p<0.001), Gensini score (OR:1.14; p=0.002), and Prognostic Nutritional Index (OR:0.73; p=0.003) were independent predictors of good CCC. ROC analysis showed high discriminative ability (AUC=0.958; 95% CI: 0.93-0.98), with a cut-off value of >49.08 (91.3% sensitivity, 90.8% specificity). Atherogenic lipid indices were not significantly associated with CCC. CONCLUSIONS: HALP score is an independent and readily available marker associated with CCC in CTO patients and may serve as a practical tool for risk stratification, highlighting the importance of inflammatory, nutritional, and immune pathways in collateral development. FUNDAMENTO: A circulação colateral coronariana (CCC) é um determinante fundamental da viabilidade miocárdica e do prognóstico em pacientes com oclusão total crônica (OTC). O escore de hemoglobina, albumina, linfócitos e plaquetas (HALP) reflete o estado nutricional, a competência imunológica e a inflamação sistêmica. OBJETIVOS: Investigar a associação entre o escore HALP e a CCC em pacientes com OTC. MÉTODOS: Este estudo retrospectivo, unicêntrico, incluiu 269 pacientes com síndrome coronariana crônica e OTC confirmada por angiografia. Os pacientes foram classificados de acordo com os graus de Rentrop e dicotomizados em CCC ruim (Rentrop 0–1; n=119) e CCC boa (Rentrop 2–3; n=150). O escore HALP, marcadores inflamatórios, índices aterogênicos e escores angiográficos foram comparados entre os grupos. Foram realizadas análises de regressão logística multivariada e de curva ROC (característica de operação do receptor). Um valor de p <0,05 foi considerado estatisticamente significativo. RESULTADOS: O escore HALP aumentou significativamente ao longo dos graus de Rentrop (p<0,001) e foi maior em pacientes com boa consistência interna do que naqueles com consistência interna ruim (75,52±13,91 vs. 35,10±11,29; p<0,001). Na análise multivariada, o escore HALP (OR: 0,88; IC 95%: 0,83–0,93; p<0,001), o escore de Gensini (OR: 1,14; p=0,002) e o Índice Prognóstico Nutricional (OR: 0,73; p=0,003) foram preditores independentes de boa consistência interna. A análise ROC mostrou alta capacidade discriminativa (AUC=0,958; IC 95%: 0,93–0,98), com um valor de corte >49,08 (91,3% de sensibilidade, 90,8% de especificidade). Os índices lipídicos aterogênicos não apresentaram associação significativa com a CCC. CONCLUSÕES: O escore HALP é um marcador independente e facilmente disponível associado à CCC em pacientes com OTC e pode servir como uma ferramenta prática para estratificação de risco, destacando a importância das vias inflamatórias, nutricionais e imunológicas no desenvolvimento de circulação colateral.
