AI Article Synopsis

  • The study examined the link between serum bilirubin levels and fragmented QRS (fQRS) in patients with acute coronary syndrome, involving 736 participants.
  • The fQRS (+) group showed significantly lower left ventricular ejection fraction and total bilirubin levels compared to the control group, indicating potential cardiac dysfunction.
  • Over a 1-year follow-up, the fQRS (+) group experienced more adverse events, suggesting that higher bilirubin levels could predict fQRS formation and related complications in these patients.

Article Abstract

To assess the relationship between serum bilirubin levels and fragmented QRS (fQRS), and their association with adverse events in patients with acute coronary syndrome. This study included a total of 736 patients. Laboratory results such as bilirubin levels, renal and liver function tests were obtained from the first available blood sample. Left ventricular ejection fraction, end-diastolic diameter and total bilirubin level were significantly lower in fQRS (+) group than in the control group (45.0 [40.0-55.0] vs 50.0 [45.0-60.0]%; p < 0.001; 4.7 [4.6-5.1] vs 4.7 [4.5-4.9] cm; p < 0.001; 0.66 [0.49-5.1] vs 0.72 [0.53-0.97] md/dl; p = 0.017); respectively. Occurrence of adverse events was significantly higher in fQRS (+) group (32.5 vs 20.5 %; p = 0.013) during mean 1-year follow-up period. Total bilirubin level is an independent predictor of fQRS formation, which is associated with the presence of adverse events in patients with acute coronary syndrome.

Background: Transarterial chemoembolisation (TACE) is standard care for unresectable, non-metastatic hepatocellular carcinoma. We aimed to evaluate the addition of lenvatinib and pembrolizumab to TACE versus dual placebo plus TACE in patients with unresectable, non-metastatic hepatocellular carcinoma.

Methods: In this multicentre, randomised, double-blind, phase 3 study (LEAP-012), patients were recruited from 137 global sites in 33 countries or regions.

Background: Muscle depletion (MD) is a critical factor that influences clinical outcomes in patients with hepatocellular carcinoma (HCC). Although its role in cancer prognosis is recognized, its integration into widely used prognostic systems remains underexplored. This study aimed to evaluate the prognostic impact of MD on overall survival (OS) in HCC patients and to improve existing noninvasive prognostic models by incorporating MD-related metrics.

Background: Bilirubin plays a crucial role in the pathophysiological processes of strokes. However, the relationship between serum bilirubin levels and the prognosis of aneurysmal subarachnoid hemorrhage (aSAH) remains unexplored. This study aims to investigate the association between serum bilirubin levels and the mortality rate of aSAH patients.
