Association of Lowering Low-Density Lipoprotein Cholesterol With Contemporary Lipid-Lowering Therapies and Risk of Diabetes Mellitus: A Systematic Review and Meta-Analysis.

ABSTRACT: Background The relationship between lowering LDL (low-density lipoprotein) cholesterol with contemporary lipid-lowering therapies and incident diabetes mellitus ( DM ) remains uncertain. Methods and Results Thirty-three randomized controlled trials (21 of statins, 12 of PCSK9 [proprotein convertase subtilisin/kexin type 9] inhibitors, and 0 of ezetimibe) were selected using Medline , Embase, and the Cochrane Central Register of Controlled Trials (inception through November 15, 2018). A total of 163 688 nondiabetic patients were randomly assigned to more intensive (83 123 patients) or less intensive (80 565 patients) lipid-lowering therapy. More intensive lipid-lowering therapy was defined as the more potent pharmacological strategy ( PCSK 9 inhibitors, higher intensity statins, or statins), whereas less intensive therapy corresponded to active control group or placebo/usual care of the trial. Metaregression and meta-analyses were conducted using a random-effects model. No significant association was noted between 1-mmol/L reduction in LDL cholesterol and incident DM for more intensive lipid-lowering therapy (risk ratio: 0.95; 95% CI , 0.87-1.04; P=0.30; R2=14%) or for statins or PCSK 9 inhibitors. More intensive lipid-lowering therapy was associated with a higher risk of incident DM compared with less intensive therapy (risk ratio: 1.07; 95% CI , 1.03-1.11; P<0.001; I2=0%). These results were driven by higher risk of incident DM with statins (risk ratio: 1.10; 95% CI , 1.05-1.15; P<0.001; I2=0%), whereas PCSK 9 inhibitors were not associated with incident DM (risk ratio: 1.00; 95% CI , 0.93-1.07; P=0.96; I2=0%; P=0.02 for interaction). Conclusions Among intensive lipid-lowering therapies, there was no independent association between reduction in LDL cholesterol and incident DM . The risk of incident DM was higher with statins, whereas PCSK 9 inhibitors had no association with risk of incident DM .

Project description:Purpose of reviewThe primary and secondary prevention of atherosclerotic cardiovascular disease (ASCVD) relies on optimizing cardiovascular health and appropriate pharmacotherapy, a mainstay of which is low-density lipoprotein-cholesterol (LDL-C) lowering. Typically, statin therapy remains the first line approach. Advances in technology and understanding of lipid metabolism have facilitated the development of several novel therapeutic targets and medications within the last decade. This review focuses on medications recently approved by the U.S. Food and Drug Administration (FDA) for the reduction of LDL-C and ASCVD risk, as well as new therapies in the pipeline.Recent findingsNovel lipid therapies aim to lower risk of ASCVD by targeting reduction of atherogenic compounds, such as LDL, lipoprotein(a) (Lp(a)), and triglyceride-rich lipoproteins. Evolocumab and alirocumab, monoclonal antibody proprotein convertase subtilisin-kexin type 9 (PCSK9) inhibitors which lower LDL-C by approximately 60%, have emerged as important therapies for use in patients with ASCVD as well as familial hypercholesterolemia (FH). Bempedoic acid, an ATP citrate lyase inhibitor, is an oral medication recently approved that can lower LDL-C by approximately 18% alone and 38% when combined with ezetimibe. Inclisiran, a small-interfering RNA (siRNA) molecule which inhibits the translation of PCSK9, is the most recently FDA-approved LDL-C lowering medication, and can reduce LDL-C by approximately 50% with twice yearly subcutaneous dosing. The cardiovascular outcome trials for bempedoic acid and inclisiran are still on-going. Evinacumab, a monoclonal antibody which targets angiopoietin-like protein 3 (ANGPTL3), has been approved for use in patients with homozygous FH. SiRNAs and anti-sense oligonucleotides (ASO) facilitating selective inhibition of the production of targeted proteins including Lp(a) and ANGLPTL3 are active areas of clinical investigation.SummaryRecently several novel LDL-C lowering medications have been approved. New therapeutic targets have been identified and present additional means of lowering LDL-C and other atherogenic compounds for patients who remain at high ASCVD risk.

Project description:ᅟ: The present study comprised 17,096 Chinese hypertensive dyslipidemia patients who received lipid-lowering treatment for > 3 months in order to investigate blood pressure (BP) as well as low-density lipoprotein cholesterol (LDL-C) goal attainment rates in Chinese hypertensive dyslipidemia patients on antidyslipidemia drugs. The factors that interfered with BP, or BP and LDL-C goal attainment rates and antihypertensive treatment patterns, were analyzed. In total, 89.9% of the 17,096 hypertensive dyslipidemia patients received antihypertensive medications mainly consisting of a calcium channel blocker (CCB) (48.7%), an angiotensin receptor antagonist (ARB) (25.4%) and an angiotensin-converting enzyme inhibitor (ACEI) (15.1%). In cardiology departments, usage rates of β-blockers (19.2%) were unusually high compared to other departments (4.0-8.3%), whereas thiazide diuretics were prescribed at the lowest rate (0.3% vs 1.2-3.6%). The overall goal attainment rates for combined BP and LDL-C as well as BP or LDL-C targets were 22.9, 31.9 and 60.1%, respectively. The lowest BP, LDL-C and BP combined with LDL-C goal attainment rates were achieved in endocrine departments (19.9, 48.9 and 12.4%, respectively). Combination therapies showed no benefit particularly for BP goal achievement. A multivariate logistic regression analysis showed that age < 65 years, alcohol consumption, diabetes, coronary heart disease (CHD), cerebrovascular disease (CVD), chronic kidney disease (CKD), body mass index (BMI) ≥ 28 kg/m2 and not achieving total cholesterol goals were independent predictors for achieving BP, LDL-C or combined BP and LDL-C goals. In summary, the BP and LDL-C goal achievement rates in Chinese dyslipidemia outpatients with hypertension were low, especially in endocrine departments. Combination therapies were not associated with improvement of the goal achievement rates. TRIAL REGISTRATION: Clinical trial registration number NCT01732952.
