Eliminate LDL cholesterol after heart attack … but only for a while
There is a clear demonstration of the inverse linear correlation between LDL cholesterol levels and clinical benefit. However, the timing of the action of lipid-lowering drugs is not clear. According to animal studies with recombinant lipoprotein A-1, the composition of atherosclerosis changes within 40 h (with variations in lipid and inflammatory contents). Progression–regression studies of atherosclerosis in humans confirm the data, highlighting a rapid change in the plaque over 5 weeks. The data are also in line with what emerges from the survival curves of the old study comparing atorvastatin 80 mg vs. placebo (Myocardial Ischaemia Reduction with Aggressive Cholesterol Lowering). The spacing of the curves occurs after only 4 weeks, indicating the precociousness of the favourable effects of powerful statins. Finally, a recent Odyssey post hoc analysis compared the risk of cardiac death and coronary revascularization between a group in which alirocumab lowered LDL cholesterol to below 15 mg (Group 1 and in which the drug was therefore stopped) against the subjects in the placebo group (Group 2), applying a propensity score matching. The primary endpoint occurred in a lower percentage of patients in Group 1 (6.4 vs. 8.4%). Furthermore, patients in Group 1 had a significantly lower hazard ratio (HR) for major adverse cardiovascular events [0.72; 95% confidence interval (CI) 0.51–0.997; P = 0.047] compared with the entire alirocumab group vs. placebo (HR 0.85; 95% CI 0.78–0.93; P < 0.001). According to these preliminary observations, aggressive and early treatment of hypercholesterolaemia in subjects with acute coronary syndrome translates into improved clinical results compared with a strategy that provides for more gradual control. These data will need to be confirmed through further prospective clinical studies and ideally with early conducted atherosclerosis regression studies.
期刊介绍:
The European Heart Journal Supplements (EHJs) is a long standing member of the ESC Journal Family that serves as a publication medium for supplemental issues of the flagship European Heart Journal. Traditionally EHJs published a broad range of articles from symposia to special issues on specific topics of interest.
The Editor-in-Chief, Professor Roberto Ferrari, together with his team of eminent Associate Editors: Professor Francisco Fernández-Avilés, Professors Jeroen Bax, Michael Böhm, Frank Ruschitzka, and Thomas Lüscher from the European Heart Journal, has implemented a change of focus for the journal. This entirely refreshed version of the European Heart Journal Supplements now bears the subtitle the Heart of the Matter to give recognition to the focus the journal now has.
The EHJs – the Heart of the Matter intends to offer a dedicated, scientific space for the ESC, Institutions, National and Affiliate Societies, Associations, Working Groups and Councils to disseminate their important successes globally.
