The LDL/HDL ratio predicts long-term risk of coronary revascularization in ST-segment elevation myocardial infarction...

Area of Science:

• Cardiology
• Biochemistry
• Public Health

Background:

• Clinical indicators offer limited long-term prognostic value for ST-segment elevation myocardial infarction (STEMI) patients post-percutaneous coronary intervention (PCI).
• The ratio of low-density lipoprotein (LDL) to high-density lipoprotein (HDL) cholesterol is a potential reliable predictor of long-term outcomes in these patients.

Purpose of the Study:

• To investigate the association between the LDL/HDL ratio and the long-term prognosis of STEMI patients undergoing PCI.
• To determine if the LDL/HDL ratio can serve as an independent risk factor for adverse cardiovascular events.

Main Methods:

• A cohort study involving 915 STEMI patients who underwent PCI between January 2009 and December 2011 in China.
• Patients were stratified into three groups based on their LDL/HDL ratio (low, medium, high) using the three-quantile method.
• Long-term follow-up (average 112.2 months) collected data on all-cause death and major adverse cardiovascular events, including coronary revascularization.

Main Results:

• The high LDL/HDL group exhibited a significantly higher rate of coronary revascularization (28.52%) compared to the low (17.38%) and medium (19.34%) groups.
• An elevated LDL/HDL ratio was identified as an independent risk factor for long-term coronary revascularization (Hazard Ratio=1.231, P=0.028).
• Specifically, patients with an LDL/HDL ratio ≥ 2.595 had a significantly increased risk of requiring coronary revascularization.

Conclusions:

• An increased LDL/HDL ratio is an independent predictor of long-term coronary revascularization in STEMI patients treated with PCI.
• The LDL/HDL ratio can aid in stratifying risk and guiding clinical management for STEMI patients post-PCI.
