Apo A1/Apo B ratio and acute coronary syndrome among peritoneal dialysis patients

Area of Science:

• Cardiology
• Nephrology
• Biochemistry

Background:

• Acute coronary syndrome (ACS) is a significant concern for patients undergoing continuous ambulatory peritoneal dialysis (CAPD).
• The relationship between apoprotein profiles and ACS risk in CAPD patients remains incompletely understood.
• This study investigates the predictive value of apoproteins in ACS development among CAPD patients.

Purpose of the Study:

• To examine the association between baseline apoprotein levels, specifically the apoprotein A1 (Apo A1)/apoprotein B (Apo B) ratio, and the incidence of ACS.
• To identify apoprotein markers that can predict future ACS events in patients on CAPD.

Main Methods:

• A retrospective study included 81 CAPD patients.
• The primary outcome was the occurrence of ACS.
• Cox regression analysis was employed to assess the relationship between the Apo A1/Apo B ratio and ACS incidence.

Main Results:

• During follow-up, 41.98% of CAPD patients experienced ACS.
• Patients with ACS exhibited higher levels of total cholesterol, LDL-C, C-reactive protein, and Apo B.
• Lower levels of hemoglobin and the Apo A1/Apo B ratio were observed in the ACS group.
• A significantly lower incidence of ACS was noted in patients with an Apo A1/Apo B ratio ≥ 1.105 compared to those with a ratio < 1.105 (33.33% vs. 75.56%, p=0.03).
• The Apo A1/Apo B ratio was independently associated with ACS (RR, 0.06; 95% CI, 0.00-0.77; p=0.03).

Conclusions:

• The Apo A1/Apo B ratio is strongly associated with ACS in CAPD patients.
• This ratio may serve as a valuable predictor for future ACS events in this patient population.
• Further research could explore therapeutic strategies targeting apoprotein levels to mitigate ACS risk in CAPD patients.
