Atorvastatin Reduces First and Subsequent Vascular Events Across Vascular Territories: The SPARCL Trial.

Background: In the SPARCL (Stroke Prevention by Aggressive Reduction in Cholesterol Levels) trial, atorvastatin was compared with placebo in 4,731 participants with recent stroke or transient ischemic attack and no known coronary heart disease. Atorvastatin reduced the first occurrence of stroke and the first occurrence of a composite of vascular events.

Objectives: The aim of this post hoc analysis was to assess the occurrence of all (first and subsequent) vascular events and the effect of atorvastatin to reduce these events by vascular territory (cerebrovascular, coronary, or peripheral) in SPARCL.

Atorvastatin Has a Dose-Dependent Beneficial Effect on Kidney Function and Associated Cardiovascular Outcomes: Post Hoc Analysis of 6 Double-Blind Randomized Controlled Trials.

Background Kidney function decreases during the lifetime, and this decline is a powerful predictor of both kidney and cardiovascular outcomes. Statins lower cardiovascular risk, which may relate to beneficial effects on kidney function. We studied whether atorvastatin influences kidney function decline and assessed the association between individual kidney function slopes and cardiovascular outcome.

Body Weight Variability and Cardiovascular Outcomes in Patients With Type 2 Diabetes Mellitus.

Background: Some studies have shown that body weight variability is a risk factor for cardiovascular events, but this has not been studied in subjects with diabetes mellitus.

Methods And Results: We measured intraindividual variations in body weight from baseline and follow-up visits in 6408 subjects with type 2 diabetes mellitus from 3 clinical trials. The primary end point, any coronary event, was a composite of coronary heart disease death, myocardial infarction, resuscitated cardiac arrest, coronary revascularization, and unstable or new-onset angina.

High plasma FGF21 levels predicts major cardiovascular events in patients treated with atorvastatin (from the Treating to New Targets [TNT] Study).

Background: Higher plasma fibroblast growth factor 21 (FGF21) levels predict incident cardiovascular events in type 2 diabetes patients. However, whether FGF21 levels predict cardiovascular events in statin-treated patients in the general population is unknown. We investigated whether FGF21 levels predict major cardiovascular event (MCVE) in the Treating to New Targets (TNT) trial participants.

Relationship of High-Density Lipoprotein Cholesterol With Renal Function in Patients Treated With Atorvastatin.

Background: It is not known whether the concentration of high-density lipoprotein (HDL) cholesterol is related to renal function in statin-treated patients. We therefore investigated whether HDL cholesterol levels predicted renal function in atorvastatin-treated patients in the TNT (Treating to New Targets) trial.

Methods And Results: A total of 9542 participants were included in this analysis.

Visit-to-visit variability of lipid measurements as predictors of cardiovascular events.

Background: Higher visit-to-visit variability in risk factors such as blood pressure and low-density lipoprotein (LDL)-cholesterol are associated with an increase in cardiovascular (CV) events.

Objective: The purpose of this study was to determine whether variability in high-density lipoprotein cholesterol (HDL-C) and triglyceride levels predicted coronary and CV events in a clinical trial population with known coronary disease.

Methods: We assessed intraindividual variability in fasting high-density lipoprotein (HDL)-cholesterol, triglyceride, and LDL-cholesterol measurements among 9572 patients in the Treating to New Targets trial and correlated the results with coronary events over a median follow-up of 4.

Effect of atorvastatin, cholesterol ester transfer protein inhibition, and diabetes mellitus on circulating proprotein subtilisin kexin type 9 and lipoprotein(a) levels in patients at high cardiovascular risk.

Background: Proprotein subtilisin kexin type 9 (PCSK9) and lipoprotein (a) [Lp(a)] levels are causative risk factors for coronary heart disease.

Objectives: The objective of the study was to determine the impact of lipid-lowering treatments on circulating PCSK9 and Lp(a).

Methods: We measured PCSK9 and Lp(a) levels in plasma samples from Investigation of Lipid Level Management to Understand its Impact in Atherosclerotic Events trial patients with coronary heart disease and/or type II diabetes (T2D) mellitus.

Effectiveness of Lipid-Lowering Statin Therapy in Patients With and Without Psoriasis.

Background: Psoriasis is associated with dyslipidemia and metabolic syndrome, and has been linked to an increased cardiovascular risk. The aim of this study was to compare baseline characteristics and effects of statin therapy on lipid levels and cardiovascular outcomes in patients with and without psoriasis.

Methods: This post-hoc analysis assessed patients from one primary cardiovascular prevention statin trial (Collaborative AtoRvastatin Diabetes Study [CARDS]) and two secondary cardiovascular prevention statin trials (Treating to New Targets [TNT] and Incremental Decrease in End Points Through Aggressive Lipid Lowering [IDEAL]).

Early, intensive statin treatment reduces 'hard' cardiovascular outcomes after acute coronary syndrome.

Background Early, intensive statin treatment is the standard of care after acute coronary syndrome (ACS). However, the benefit of this approach to prevent major adverse cardiovascular events has been demonstrated in only one randomised, placebo controlled trial. The Myocardial Ischemia Reduction with Aggressive Cholesterol Lowering (MIRACL) trial demonstrated that atorvastatin 80 mg daily, compared with placebo, reduced time to first occurrence of death, non-fatal myocardial infarction, resuscitated cardiac arrest, or hospitalisation for unstable angina (stroke not included) during the 16 week period following ACS.

Body-Weight Fluctuations and Outcomes in Coronary Disease.

Background: Body-weight fluctuation is a risk factor for death and coronary events in patients without cardiovascular disease. It is not known whether variability in body weight affects outcomes in patients with coronary artery disease.

Methods: We determined intraindividual fluctuations in body weight from baseline weight and follow-up visits and performed a post hoc analysis of the Treating to New Targets trial, which involved assessment of the efficacy and safety of lowering low-density lipoprotein cholesterol levels with atorvastatin.

Oxidized Phospholipids on Apolipoprotein B-100 and Recurrent Ischemic Events Following Stroke or Transient Ischemic Attack.

Background: Biomarkers to predict recurrent stroke and targets of therapy to prevent stroke are lacking.

Objectives: This study evaluated whether patients with prior cerebrovascular events and elevated levels of oxidized phospholipids on apolipoprotein B-100 (OxPL-apoB), but without prior coronary artery disease (CAD), are at risk for recurrent stroke and CAD events following high-dose statin therapy.

Methods: In the SPARCL (Stroke Prevention by Aggressive Reduction in Cholesterol Levels) trial, OxPL-apoB levels were measured in 4,385 patients with stroke or transient ischemic attack at baseline and in 3,106 patients at 5 years following randomization to placebo or 80 mg atorvastatin.

Relation of Variability of Low-Density Lipoprotein Cholesterol and Blood Pressure to Events in Patients With Previous Myocardial Infarction from the IDEAL Trial.

In patients with previous myocardial infarction (MI), aggressive hypertension control and low-density lipoprotein cholesterol (LDL-C) reduction are important secondary prevention measures. However, residual risk remains despite aggressive treatment. Whether variability in blood pressure (BP) and LDL-C can explain this residual risk is not known.

Differing predictive relationships between baseline LDL-C, systolic blood pressure, and cardiovascular outcomes.

Background: Traditional cardiovascular risk factors, such as hypertension and dyslipidemia, predispose individuals to cardiovascular disease, particularly patients with diabetes. We investigated the predictive value of baseline systolic blood pressure (SBP) and low-density lipoprotein cholesterol (LDL-C) on the risk of vascular outcomes in a large population of patients at high risk of future cardiovascular events.

Methods: Data were pooled from the TNT (Treating to New Targets), CARDS (Collaborative Atorvastatin Diabetes Study), and IDEAL (Incremental Decrease in End-Points Through Aggressive Lipid Lowering) trials and included a total of 21,727 patients (TNT: 10,001; CARDS: 2838; IDEAL: 8888).

Emerging Cardiovascular Disease Biomarkers and Incident Diabetes Mellitus Risk in Statin-Treated Patients With Coronary Artery Disease (from the Treating to New Targets [TNT] Study).

Whether biomarkers associated with cardiovascular disease risk also predict incident diabetes mellitus (DM) is unknown. Our objective was to determine if a panel of 18 biomarkers previously associated with risk of cardiovascular disease also predicts incident DM in statin-treated patients with coronary artery disease (CAD). The Treating to New Targets (TNT) study is a randomized trial that compared the efficacy of high (80 mg) versus low (10 mg) dose atorvastatin for the secondary prevention of coronary heart disease events.

2013 Cholesterol Guidelines Revisited: Percent LDL Cholesterol Reduction or Attained LDL Cholesterol Level or Both for Prognosis?

Background: The 2013 American College of Cardiology (ACC)/American Heart Association (AHA) guideline on the treatment of blood cholesterol recommends moderate- to high-intensity statins for patients with atherosclerotic cardiovascular disease but departs from the traditional treat-to-target approach. Whether percent low-density lipoprotein cholesterol (LDL-C) reduction or attained LDL-C levels add incremental prognostic value to statin dose is not known.

Methods: Patients in the Treating to New Targets (TNT), Incremental Decrease in Endpoints through Aggressive Lipid Lowering (IDEAL), and Stroke Prevention by Aggressive Reduction in Cholesterol Levels (SPARCL) trials (patient-level data) randomized to a statin arm (atorvastatin 80 mg/10 mg or simvastatin 20 mg) were chosen.

Effect of high-dose atorvastatin on the cardiovascular risk associated with individual components of metabolic syndrome: a subanalysis of the Treating to New Targets (TNT) study.

Aims: To investigate the impact of intensive lipid-lowering with high-dose atorvastatin on the cardiovascular risk associated with individual metabolic syndrome components [high body mass index (BMI), elevated triglycerides, low high-density lipoprotein (HDL) cholesterol, hypertension and elevated fasting glucose] in patients with coronary heart disease (CHD).

Methods: Patients with clinically evident, stable CHD and low-density lipoprotein (LDL) cholesterol <3.4 mmol/l (130 mg/dl) were randomized to double-blind therapy with atorvastatin 10 mg/day (n = 5006) or 80 mg/day (n = 4995) after an 8-week open-label run-in with atorvastatin 10 mg.

Fasting triglycerides predict recurrent ischemic events in patients with acute coronary syndrome treated with statins.

Background: Most patients with acute coronary syndrome (ACS) are treated with statins, which reduce atherogenic triglyceride-rich lipoproteins. It is uncertain whether triglycerides predict risk after ACS on a background of statin treatment.

Objectives: This study examined the relationship of fasting triglyceride levels to outcomes after ACS in patients treated with statins.

Effect of atorvastatin on C-reactive protein and benefits for cardiovascular disease in patients with type 2 diabetes: analyses from the Collaborative Atorvastatin Diabetes Trial.

Aims/hypothesis: We investigated whether atorvastatin 10 mg daily lowered C-reactive protein (CRP) and whether the effects of atorvastatin on cardiovascular disease (CVD) varied by achieved levels of CRP and LDL-cholesterol.

Methods: CRP levels were measured at baseline and 1 year after randomisation to atorvastatin in 2,322 patients with type 2 diabetes (40-75 years, 69% males) in a secondary analysis of the Collaborative Atorvastatin Diabetes Study, a randomised placebo-controlled trial. We used Cox regression models to test the effects on subsequent CVD events (n = 147) of CRP and LDL-cholesterol lowering at 1 year.

Visit-to-visit low-density lipoprotein cholesterol variability and risk of cardiovascular outcomes: insights from the TNT trial.

Background: Studies demonstrate that lowering low-density lipoprotein cholesterol (LDL-C) using a statin is associated with significant reduction in cardiovascular events. Whether visit-to-visit variability in LDL-C levels affects cardiovascular outcomes is unknown.

Objectives: This study sought to evaluate the role of visit-to-visit variability in LDL-C levels on cardiovascular outcomes.

Relationship of oxidized phospholipids on apolipoprotein B-100 to cardiovascular outcomes in patients treated with intensive versus moderate atorvastatin therapy: the TNT trial.

Background: Oxidized phospholipids on apolipoprotein B-100 (OxPL-apoB) is a biomarker of increased risk for major adverse cardiovascular events (MACE) in community cohorts, but its role in patients with stable coronary heart disease (CHD) is unknown.

Objectives: This study sought to examine the relationship between these oxidative biomarkers and cardiovascular outcomes in patients with established CHD.

Methods: In a random sample from the TNT (Treating to New Targets) trial, OxPL-apoB levels were measured in 1,503 patients at randomization (after an 8-week run-in period taking atorvastatin 10 mg) and 1 year after being randomized to atorvastatin 10 or 80 mg.

Prediction of cardiovascular events in statin-treated stable coronary patients of the treating to new targets randomized controlled trial by lipid and non-lipid biomarkers.

Unlabelled: Several plasma non-lipid biomarkers have been shown to predict major cardiovascular events (MCVEs) in population studies. Our objective was to investigate the relationship between lipid and non-lipid biomarkers levels achieved during statin therapy and the incidence of MCVEs in patients with stable coronary heart disease (CHD). We conducted a substudy of the TNT (Treating to New Targets) study, which was a randomized trial that compared the efficacy of high (80 mg) versus low (10 mg) dose atorvastatin for the secondary prevention of CHD.

Very low levels of atherogenic lipoproteins and the risk for cardiovascular events: a meta-analysis of statin trials.

Background: Levels of atherogenic lipoproteins achieved with statin therapy are highly variable, but the consequence of this variability for cardiovascular disease risk is not well-documented.

Objectives: The aim of this meta-analysis was to evaluate: 1) the interindividual variability of reductions in low-density lipoprotein cholesterol (LDL-C), non-high-density lipoprotein cholesterol (non-HDL-C), or apolipoprotein B (apoB) levels achieved with statin therapy; 2) the proportion of patients not reaching guideline-recommended lipid levels on high-dose statin therapy; and 3) the association between very low levels of atherogenic lipoproteins achieved with statin therapy and cardiovascular disease risk.

Methods: This meta-analysis used individual patient data from 8 randomized controlled statin trials, in which conventional lipids and apolipoproteins were determined in all study participants at baseline and at 1-year follow-up.

Statin and the risk of renal-related serious adverse events: Analysis from the IDEAL, TNT, CARDS, ASPEN, SPARCL, and other placebo-controlled trials.

A recent study has shown an association between high-potency statins and risk of acute kidney injury. However, these data are from observational studies, and it is not clear if similar signal is seen from randomized controlled trials. We evaluated the risk of renal-associated serious adverse events (SAEs) using statins versus placebo trials and the high-dose versus low-dose statin trials that were available to us.

LADA and CARDS: a prospective study of clinical outcome in established adult-onset autoimmune diabetes.

Objective: Diabetes-associated autoantibodies can be detected in adult-onset diabetes, even when initially non-insulin requiring, i.e., with latent autoimmune diabetes.
