Systematic, immediate in-hospital initiation of lipid-lowering drugs during acute coronary events improves lipid control

Abstract

Background: Patients who have had a coronary heart attack often go completely untreated for hypercholesterolemia. We investigated whether immediate initiation of lipid-lowering drugs during hospitalization for acute coronary events increases the proportion of correctly treated patients compared to referred treatment as recommended by current guidelines. Methods: This prospective, multicenter study randomized 57 hypercholesterolemic patients hospitalized for acute coronary events to immediate in-hospital initiation or to referred initiation of lipid-lowering drugs by primary care physicians 3 months after unsuccessful nutritional intervention. Results: After 6 months, 53 patients were available for follow-up. More patients in the immediate initiation group (26/30 patients, 87%) were treated with lipid-lowering drugs than in the referred initiation-group (13/23 patients, 57%, P=0.03). Twenty-seven patients (87%) in the immediate initiation group versus 17 patients (65%) in the referred initiation group had a 10% or greater decrease in total cholesterol or a 15% or greater decrease in LDL-cholesterol (P=0.18). Although statistically not significant, there was a trend to improved lipid values in the immediate initiation group compared to the referred initiation group (TC, -21.1 vs. -13.8% (P=0.08); LDL-C, -28.2 vs. -18.9% (P=0.13); HDL-C, +10.8 vs. +5% (P=0.44); TC/HDL-C ratio, -24.7 vs. -15.1% (P=0.22)), and the LDL-C/HDL-C ratio was -34.1 vs. -19.1% (P=0.04, P=NS after Bonferroni correction). Conclusion: The immediate initiation of lipid-lowering drugs in hypercholesterolemic patients hospitalized for acute coronary events increases the rate of correctly treated patients and has the potential to improve lipid control.
