Cardiovascular disease in chronic obstructive pulmonary disease.

Smoking is a major cause of chronic obstructive pulmonary disease (COPD) and cardiovascular disorders, including coronary heart disease (CHD) and peripheral arterial disease. Smoking-induced inflammation and other risk factors like dyslipidemia cause vascular endothelial damage via oxidative stress, and a vicious cycle with the characteristics of atherosclerosis ensues. Inflammatory cytokines stimulate hepatic acute-phase protein production, and C-reactive protein is now used widely to assess inflammation in the arterial wall.

Effects of rosuvastatin, atorvastatin, simvastatin, and pravastatin on atherogenic dyslipidemia in patients with characteristics of the metabolic syndrome.

The metabolic syndrome (MS) is a constellation of coronary risk factors. Atherogenic dyslipidemia is an important factor in cardiovascular risk in these patients, and treatment of atherogenic dyslipidemia has been identified as an important goal of therapy in patients with MS. This post hoc analysis of data from a 6-week, randomized, open-label, parallel-group, comparative trial (Statin Therapies for Elevated Lipid Levels compared Across doses to Rosuvastatin [STELLAR]) assessed the effects of rosuvastatin 10, 20, and 40 mg, atorvastatin 10, 20, 40, and 80 mg, simvastatin 10, 20, 40, and 80 mg, and pravastatin 10, 20, and 40 mg on plasma lipids in hypercholesterolemic patients (low-density lipoprotein cholesterol >/=160 and <250 mg/dl; triglycerides <400 mg/dl) who had >/=3 of the 5 National Cholesterol Education Program Adult Treatment Panel III criteria for MS (body mass index >30 kg/m(2) substituted for waist circumference).

Effects of rosuvastatin versus atorvastatin, simvastatin, and pravastatin on non-high-density lipoprotein cholesterol, apolipoproteins, and lipid ratios in patients with hypercholesterolemia: additional results from the STELLAR trial.

Background: Non-high-density lipoprotein cholesterol (HDL-C), apolipoprotein (apo) B, and lipid and apolipoprotein ratios that include both atherogenic and antiatherogenic lipid components have been found to be strong predictors of coronary heart disease risk.

Objective: The goal of this study was to examine prospectively the effects of rosuvastatin, atorvastatin, simvastatin, and pravastatin across dose ranges on non-HDL-C, apo B, apo A-I, and total cholesterol (TC):HDL-C, low-density lipoprotein cholesterol (LDL-C):HDL-C, non-HDL-C:HDL-C, and apo B:apo A-I ratios in patients with hypercholesterolemia (LDL-C > or =160 mg/dL and <250 mg/dL and triglycerides <400 mg/dL) in the Statin Therapies for Elevated Lipid Levels compared Across doses to Rosuvastatin (STELLAR) trial.

Methods: In this randomized, Multicenter, parallel-group, open-label trial (4522IL/0065), patients > or =18 years of age received rosuvastatin 10, 20, 40, or 80 mg; atorvastatin 10, 20, 40, or 80 mg; simvastatin 10, 20, 40, or 80 mg; or pravastatin 10, 20, or 40 mg for 6 weeks.

Clinical outcomes in managed-care patients with coronary heart disease treated aggressively in lipid-lowering disease management clinics: the alliance study.

Objectives: This study sought to determine if an aggressive, focused low-density lipoprotein cholesterol (LDL-C)-lowering strategy was superior to usual care for coronary heart disease (CHD) patients enrolled in health maintenance organization or Veterans Administration settings.

Background: Statin therapy benefits are well established. No prospective, randomized studies have tested strategies to optimize these benefits in a "real-world" setting.

Safety of rosuvastatin.

The safety and tolerability of rosuvastatin were assessed (as of August 2003) using data from 12,400 patients who received 5 to 40 mg of rosuvastatin in a multinational phase II/III program, which represented 12,212 patient-years of continuous exposure to rosuvastatin. An integrated database was used to examine adverse events and laboratory data. In placebo-controlled trials, adverse events, irrespective of causality assessment, occurred in 57.

Implications of recent clinical trials for the National Cholesterol Education Program Adult Treatment Panel III Guidelines.

The Adult Treatment Panel III (ATP III) of the National Cholesterol Education Program issued an evidence-based set of guidelines on cholesterol management in 2001. Since the publication of ATP III, 5 major clinical trials of statin therapy with clinical end points have been published. These trials addressed issues that were not examined in previous clinical trials of cholesterol-lowering therapy.

Plasma homocysteine levels in living kidney donors before and after uninephrectomy.

An increased prevalence of hyperhomocysteinemia has been observed among patients with end-stage renal disease, and numerous studies have demonstrated that kidney function is one of the most important determinants of plasma total homocysteine (tHcy) concentration. In an effort to understand the mechanism of hyperhomocysteinemia in renal disease, we chose, as our model, living kidney donors who had undergone uninephrectomy. We studied 10 living kidney donors and measured fasting plasma tHcy, plasma creatinine, folate, vitamins B(12) and B(6), and high-sensitivity C-reactive protein (hsCRP) 24 hours before nephrectomy and 2 days, 6 weeks, and 6 months after nephrectomy compared to the values 24 hours before nephrectomy.

Effects of lipid-altering treatment in diabetes mellitus and the metabolic syndrome.

The metabolic syndrome (MS) poses an increased risk for the development of diabetes mellitus and cardiovascular events. The syndrome typically includes dyslipidemia, characterized by elevated plasma triglycerides and low high-density lipoprotein cholesterol concentrations. Retrospective analyses of coronary artery disease outcomes trials in patient subpopulations with diabetes or the MS indicate that lipid-altering therapies provide benefits for patients with the MS at least as much as observed in patients without diabetes or the MS.

Rosuvastatin improves the atherogenic and atheroprotective lipid profiles in patients with hypertriglyceridemia.

Background: We examined the effects of rosuvastatin treatment on triglyceride levels and lipid measures in a parallel-group multicenter trial (4522IL/0035) in patients with hypertriglyceridemia (Fredrickson Type IIb or IV).

Methods: After a 6-week dietary lead-in period while on a National Cholesterol Education Program step I diet, 156 patients with fasting triglyceride levels >/= 300 and < 800 mg/dl were randomized to 6 weeks of double-blinded treatment: once-daily rosuvastatin of 5, 10, 20, 40 or 80 mg or placebo. The primary end point was mean percentage change from baseline in total serum triglyceride levels at week 6 as determined by analysis of variance.

Comparison of health-related quality-of-life outcomes of men and women after coronary artery bypass surgery through 1 year: findings from the POST CABG Biobehavioral Study.

Background: Women undergoing coronary artery bypass graft (CABG) surgery have a worse medical condition and fewer social and financial resources than men. Some studies have found that women recover less well than men after CABG, whereas others have found women's outcomes comparable to those of men. Past studies of health-related quality of life after CABG have too few women for adequate comparison with men and have not included patients whose data are not available at baseline (eg, emergency CABG), limiting generalizability.

Effect on high-density lipoprotein cholesterol of maximum dose simvastatin and atorvastatin in patients with hypercholesterolemia: results of the Comparative HDL Efficacy and Safety Study (CHESS).

Background: Previous studies have shown that effects on high-density lipoprotein cholesterol (HDL-C) may differ among statins.

Methods: A multicenter, randomized, double-blind, parallel-dose study was conducted in 917 hypercholesterolemic patients to compare the efficacy of 80 mg/d simvastatin versus 80 mg/d atorvastatin on HDL-C and apolipoprotein (apo) A-I for 24 weeks. Efficacy was assessed as the means of weeks 6 and 12 and weeks 18 and 24.

Differences in medical care and disease outcomes among black and white women with heart disease.

Background: The risk of cardiovascular mortality is higher among black women than white women, and the reasons for this disparity are largely unexplored. We sought to evaluate differences in medical care and clinical outcomes among black and white women with established coronary artery disease.

Methods And Results: Among the 2699 women enrolled in the Heart and Estrogen/progestin Replacement Study (HERS), we used Cox proportional hazards models to determine the association of race with risk of coronary heart disease (CHD) events independent of major cardiovascular risk factors or medical therapies.

Comparative effects of simvastatin and atorvastatin in hypercholesterolemic patients with characteristics of metabolic syndrome.

Background: Hypercholesterolemic patients with metabolic syndrome (MS) are at high risk for coronary heart disease. The National Cholesterol Education Program (NCEP) Adult Treatment Panel III (ATP III) guidelines provide the option of aggressively lowering low-density lipoprotein cholesterol (LDL-C) in hypercholesterolemic patients with MS.

Objective: The lipid-modifying efficacy of simvastatin and atorvastatin in hypercholesterolemic patients with MS as defined by NCEP ATP III was assessed.

A dose-ranging study of a new, once-daily, dual-component drug product containing niacin extended-release and lovastatin.

Background: Combination therapy for dyslipidemia holds promise as effective treatment for patients with multiple lipid disorders, especially those at high risk.

Hypothesis: This study evaluated dose-response relationships and safety of a new dual-component drug product containing niacin extended-release (niacin ER) and lovastatin.

Methods: The 28-week double-blind multicenter trial randomized 237 patients with type IIA or IIB hyperlipidemia to one of four escalating-dose treatment groups: niacin ER/lovastatin 1,000/20 mg, niacin ER/lovastatin 2,000/40 mg, niacin ER 2,000 mg, or lovastatin 40 mg.

Guidelines for lowering lipids to reduce coronary artery disease risk: a comparison of rosuvastatin with atorvastatin, pravastatin, and simvastatin for achieving lipid-lowering goals.

Both the National Cholesterol Education Program (NCEP) Adult Treatment Panel (ATP) III and the Second Joint Task Force of European Societies guidelines have established low-density lipoprotein (LDL) cholesterol goals for lipid-lowering treatment to reduce the risk of coronary artery disease. Data from 3 trials that compared rosuvastatin 10 mg (n = 389) with atorvastatin 10 mg (n = 393) and 2 trials that compared rosuvastatin 10 mg (n = 226) with pravastatin 20 mg (n = 252) and simvastatin 20 mg (n = 249) were pooled separately to compare the achievement of LDL cholesterol goals over 12 weeks of treatment in hypercholesterolemic patients. Noncomparative pooling of rosuvastatin 10 mg results from all 5 trials (n = 615) showed that 80% achieved NCEP ATP III goals and 81% achieved the European goal of <3.

Angiographic changes in saphenous vein grafts are predictors of clinical outcomes.

Background: Previous studies have suggested that angiographic evidence of disease progression in coronary arteries increases the risk of subsequent coronary clinical events. This study ascertained whether patients enrolled in the Post Coronary Artery Bypass Graft Clinical Trial (POST CABG) who had substantial progression of atherosclerosis in >or=1 saphenous vein grafts (on the basis of assessment of baseline and follow-up angiograms obtained 4-5 years after study entry), but who had not reported clinical symptoms before follow-up angiography, were at a higher risk of subsequent events than patients who did not have substantial progression of atherosclerosis (decrease >or=0.6 mm in lumen diameter at site of greatest change from baseline).

Dose--Response Study of Colestipol Tablets in Patients with Moderate Hypercholesterolemia.

The purpose of the study was to evaluate the efficacy and safety of a new formulation of colestipol provided in table form. This was a randomized, double-blind, placebo-controlled, multicenter, dose-ranging study. A total of 196 patients with primary hypercholesterolemia who were following a low-fat, low-cholesterol diet (NCEP Step I diet), and having mean low-density lipoprotein cholesterol (LDL-C) levels greater-than-or-equal4.
