• Predictors of lower HDL levels (<32 mg/dL) were male gender (P < .001), diabetes mellitus (P = .03), renal failure (P = .01), higher low–density lipoprotein and total cholesterol (P < .001, respectively), triglycerides (P < .001), and white blood cells (P < .001), aging (P < .001), previous myocardial infarction (P = .02) and hemoglobin (P < .001), treatment with angiotensin–receptor blockers (P < .001), and statins (P = .002).

Results

• The HDL–C levels were significantly inversely associated with prevalence of CAD (P < .001, adjusted odds ratio [OR] [95% confidence interval, CI] = 1.35 [1.25–1.45], P < .001), and HDL–C <44 mg/dL was best the predictive value of the risk of CAD, (adjusted OR [95%CI] = 1.61 [1.24–2.1], P < .001).
• Authors found significant association between HDL–C and the risk of CAD; a value <44 mg/dL was the best cutoff in the prediction of CAD.

Abstract
Our goal was to estimate the role of high-density lipoprotein cholesterol (HDL-C) in predicting the prevalence and extent of coronary artery disease (CAD) in 3280 patients undergoing coronary angiography. Predictors of lower HDL levels (
