Association of non-HDL-C-to-HDL-C ratio with coronary lesions and its prognostic performance in first-onset NSTEMI.

Aim: The study sought to investigate the association of non-high-density-lipoprotein cholesterol-to-high-density-lipoprotein cholesterol ratio (NON-HDL-C:HDL-C) with coronary lesions and major adverse cardiovascular events (MACE) in first-onset non-ST-segment elevation acute myocardial infarction. Methods: A cohort of 426 patients undergoing early invasive therapy was enrolled in the final analysis. MACE included cardiac death, nonfatal myocardial infarction, target vessel revascularization, congestive heart failure and nonfatal stroke. Results: NON-HDL-C:HDL-C revealed a powerful diagnostic performance for multiple cardiovascular risk factors (p < 0.05). NON-HDL-C:HDL-C was an independent predictor for severe coronary lesions and MACE (p < 0.05). Subgroup analysis further examined the robustness, especially in elderly, male, dyslipidemic or nondiabetic patients. Conclusion: NON-HDL-C:HDL-C is associated with coronary lesions and prognosis in non-ST-segment elevation acute myocardial infarction.
