(HealthDay)—Achieving targets of low-density lipoprotein (LDL), as measured by LDL particle number (LDL-P) compared with LDL-cholesterol (LDL-C), is cost-effective, according to a study published in the Feb. 1 issue of The American Journal of Cardiology.
Michael Grabner, Ph.D., from HealthCore Inc. in Wilmington, Del., and colleagues examined the cost-effectiveness of LDL-lowering therapy guided by LDL-P among patients selected from the HealthCore Integrated Research Database who were followed for 12 to 36 months. The LDL-P cohort included patients who achieved LDL-P <1,000 nmol/L, while those without LDL-P tests but who achieved LDL-C <100 mg/dL were included in the LDL-C cohort. At the 12-, 24-, and 36-month follow-up, each cohort included 2,094, 1,242, and 705 patients, respectively.
The researchers found that, compared with patients in the LDL-C cohort, those in the LDL-P cohort received more aggressive lipid-lowering therapy and had fewer cardiovascular disease (CVD) events during follow-up. Over time, this correlated with increased pharmacy costs and lower medical costs. The incremental cost-effectiveness ratio estimates varied from $23,131, $3,439, and −$4,555 per CVD event avoided at 12, 24, and 36 months, respectively.
"LDL-lowering therapy guided by LDL-P was demonstrated to be cost-effective, with greater clinical and economic benefit seen over longer time horizons and with the increased use of generic statins," the authors write.
