Almost half of first cardiovascular events occur in individuals with no known risk factors. Attempts in the last decade to predict cardiovascular risk more accurately have led to the emergence of a novel risk factor, C-reactive protein (CRP), which has proved to be as good a risk predictor as low-density lipoprotein cholesterol. C-reactive protein is an index of inflammation that is now believed to promote directly all stages of atherosclerosis, including plaque rupture. As measured by high-sensitivity assays, high-sensitivity CRP (hs-CRP) also independently predicts recurrent events in patients with known coronary artery diseases. Recent evidence implicates hs-CRP, and thus inflammation, in the metabolic syndrome and diabetes mellitus, particularly in women. As a clinical tool for cardiovascular risk assessment, hs-CRP testing enhances information provided by lipid screening or global risk assessment. Statin therapy and other interventions can lower hs-CRP. Whether or not such reductions can prevent cardiovascular events is under investigation.

Type 2 diabetes is associated with a high prevalence of dyslipidaemia and a high incidence of cardiovascular disease. Lipid lowering therapy with HMG Co-A reductase inhibitors (statins) reduce the risk of cardiovascular events in type 2 diabetic and non-diabetic patients, effects which are believed to be partly due to improvements in vascular function. The aetiology of abnormal vascular function in type 2 diabetics is likely to be multifactorial and the pattern of vascular dysfunction in type 2 diabetes may differ from that which occurs in non-diabetic patients with dyslipidaemia. Abnormalities in endothelium derived hyperpolarising factor (EDHF) mediated vasodilation in resistance vessels may be more prominent in both type 1 and type 2 diabetes than in non-diabetic patients with endothelial dysfunction. The effects of lipid lowering therapy on vascular responsiveness may differ in type 2 diabetic patients from those found in non-diabetic patients. Statin therapy does not appear to improve responses to endothelial dependent vasodilators in type 2 diabetics, but may alter the ratio between nitric oxide (NO) and EDHF mediated responses. Fibrate therapy improves flow mediated dilation of brachial arteries in type 2 diabetic patients, but only appears to improve endothelium dependant vasodilator responses in resistance vessels when given in conjunction with co-enzyme Q.

The use of lipid-lowering drugs in diabetes is aimed primarily at reducing the large cardiovascular disease (CVD) risk burden experienced by this group of patients. Statin therapy has been shown to be highly efficacious in reducing CVD risk, both in those with and without prior CVD. Therefore, statins are the first-line lipid-lowering therapy in patients with diabetes. Patients with diabetes and established CVD should have low-density lipoprotein cholesterol (LDLC) lowered to at least 2.6 mmol/L (100 mg/dL) and, if possible, to 1.8 mmol/L (70 mg/dL). Those without prior CVD should have LDLC lowered to 2.6 mmol/L. Triglycerides should be kept less than 1.7 mmol/L (150 mg/dL) and high-density lipoprotein cholesterol (HDLC) above 1.15 mmol/L (40 mg/dL) in men and 1.2 mmol/L (46 mg/dL) in women. Additional therapy with fibrates or nicotinic acid may be needed to achieve these goals; the choice is determined by tolerance and side-effect profile. The use of nicotinic acid or fibrates on their own to achieve triglyceride or HDLC levels should be limited to those patients already at or near LDLC goals. Caution is warranted with combination therapy because muscle side effects, in particular, can increase. In type 1 diabetes, CVD risk is high but trial data are sparse. Where there is nephropathy, and where glycemic control is poor, there will often be a need for triglyceride and HDLC raising interventions as above. In the absence of these, lipid profile is often normal and focus should be on reducing CVD risk by statin therapy. If uncertainty about CVD risk status exists, consideration should be given to using CVD imaging modalities to inform intervention choice in younger patients.

The large administrative databases of health plans contain information on drug-related medical adverse events (AE) and constitute an increasingly powerful tool for the assessment of drug safety. We conducted a retrospective observational study using an administrative managed care claims database covering 9 million members from diverse regions of the United States. Patients aged >or=18 years who received >or=2 prescriptions for lipid-lowering drugs between July 1, 2000 and December 1, 2004 were included in the study. Hospitalizations with diagnosis codes (International Classification of Diseases, 9th Revision, Clinical Modification [ICD-9]) related to muscle, kidney, and liver were determined for patients exposed to 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase inhibitors (statins), fibrates, extended-release niacin, cholesterol absorption inhibitors, or statin combination therapy. A total of 473,343 patients contributed 490,988 person-years of monotherapy and 11,624 person-years of combination dyslipidemia therapy. Rates of hospitalization due to AEs in patients on monotherapy with currently available statins were similar, whereas the incidence of hospitalization for muscle disorders increased 6.7-fold with cerivastatin therapy. Patients who received a lipid-lowering medication with a concomitant cytochrome P450 3A4 (CYP3A4) inhibitor had a 6-fold increased rate of muscle disorders, including rhabdomyolysis. Hypertension was associated with a 5-fold increase in both muscle and renal events, whereas patients with diabetes mellitus had a 2.5-fold increased risk of renal events. No hospitalized cases of the index AEs were observed in study subjects during the 6-month period before initiation of the lipid-lowering drug. Statin monotherapy as currently prescribed is generally well tolerated and safe.

The metabolic syndrome appears to affect a significant proportion of the population and is associated with increased risk for development of cardiovascular disease as well as of type-2 diabetes. No single treatment for the metabolic syndrome as a whole yet exists. While the primary management of patients with the metabolic syndrome involves healthy lifestyle promotion, the atherogenic dyslipidemia is a primary target for cardiovascular disease risk reduction in these patients. Statin therapy provides effective reduction of LDL-cholesterol, which represents the primary therapeutic goal of lipid-lowering therapy in patients at risk for cardiovascular disease. Fibrates in turn are effective in normalizing lipid levels (mainly triglycerides and HDL-cholesterol) in patients with the metabolic syndrome and may improve insulin resistance. Whereas statins remain the drug of choice for patients who need to achieve the LDL-cholesterol goal, fibrate therapy may represent an alternative for those with low HDL-cholesterol and high triglyceride levels. The simultaneous use of fibrates could be indicated in patients whose LDL-cholesterol is controlled by statin therapy but whose HDL-cholesterol and/or triglycerides are still inappropriate. Such a combination, however, needs careful monitoring due to the potential hazard of adverse drug interactions. Nicotinic acid and ezetimibe may be useful agents for therapy, particularly when combined with statins. A number of emerging therapies offer potential as future options for the pharmacological treatment of metabolic syndrome.

Diabetes is associated with a high risk of cardiovascular disease. The management of dyslipidemia, a well-recognized and modifiable risk factor among patients with type 2 diabetes, is an important element in the multifactorial approach to prevent coronary heart disease. Diabetic dyslipidemia typically consists of elevated triglyceride, low high-density lipoprotein cholesterol (HDL-C), and the predominance of small dense low-density lipoprotein (LDL) particles. LDL cholesterol (LDL-C) levels in patients with diabetes are similar to those found in the rest of the population. During the past few years, clinical trials have provided evidence that lipid-lowering therapy has a similar beneficial effect on cardiovascular outcomes in diabetic and nondiabetic individuals. According to current guidelines, the primary lipid target is an LDL-C <100 mg/dL (<70 mg/dL in very high-risk patients) and, to this end, statins are the agents of choice. The appropriate management of dyslipidemia in patients with diabetes, particularly in individuals with low LDL-C, remains controversial. To achieve lipid targets, attention should be directed first toward nonpharmacologic therapeutic interventions to control dyslipidemia, such as diet, exercise, smoking cessation, weight loss, and glycemic control. Statin therapy is recommended for most subjects but, frequently, a combination of lipid-lowering agents is required. A number of combinations are possible, and several factors should be considered to improve the safety of this strategy.

Major vascular surgery is associated with a long in-hospital length of stay (LOS). Cardiac risk factors identify patients with an increased risk. Recent studies have associated statin, aspirin, and beta-blocker therapies with improved postoperative outcome. However, the effect of all these factors on LOS has not been defined. Our aims were to determine the effect of cardiac risk factors and (preventive) statin, aspirin, and beta-blocker therapy on LOS and to deduce from these factors a model that predicts LOS. In total, 2,374 patients from 1990 to 2004 were enrolled. Mean LOS was 18 +/- 9 days. Cardiac risk factors that were significantly associated with LOS in the multivariable analysis were age, previous heart failure, hypertension, diabetes mellitus, renal failure, and chronic obstructive pulmonary disease. Statin and aspirin use was associated with a shorter LOS. Beta blockers shortened LOS only in patients with underlying coronary artery disease. Together, these factors explained 14.1% of the variance in LOS. In conclusion, in-hospital LOS in patients who undergo major vascular surgery can be predicted more accurately by clinical cardiac risk factors. A significant decrease in in-hospital LOS was achieved with statin, aspirin, and beta-blocker therapies.

Cardiovascular complications are a principal cause of death rate in the patients with type 2 diabetes, that in turn contribute to cardiovascular diseases and complications in adult population. According to UKPDS data high LDL Ch level is strong predictor of CHD development in patients with type 2 diabetes and its 1 mmol/l level increase, due the coronary risk increase on 57%. Patients with type 2 diabetes have the target levels of lipids enough rigid: the total Ch < 4.5 mmol/l, LDL Ch < 2.5 mmol/l, triglycerides < 1.7 mmol/l and HDL Ch > 1 mmol/l. The results of CARDS study have shown, that the treatment of the type 2 diabetes patients with mild hypercholesterolemia without CHD by atorvastatin in a doze of 10 mg during 5 years decreased cardiovascular risk on 37%, an stroke on 48% and the total death rate on 27%. In practice, 89% of the patients with type 2 diabetes comes to light deviations in Ch level. The lipid spectrum assay of should join to the obligatory diagnostic procedures in all type 2 diabetes patients despite of the age and sex. Statin therapy in the diabetes patients is as necessary as the antidiabetic treatment.

To obtain reliable data on the epidemiology, co-morbidities and risk factor profile of peripheral arterial disease (PAD), we evaluated the clinical significance of the ankle brachial index (ABI) as an indicator of PAD in Chinese patients at high cardiovascular (CV) risk. ABI was measured in 5,646 Chinese patients at high CV risk, and PAD was defined as an ABI<0.9 in either leg. Multivariable logistic regression analyses were performed to identify factors associated with PAD. A total of 5,263 patients were analyzed, 52.9% male, mean age 67.3 years, mean body mass index (BMI) 24.2 kg/m2, mean systolic/diastolic blood pressure (SBP/DBP) 139/80.7 mmHg. The prevalence of PAD in the total group of patients was 25.4%, and the prevalence was higher in females than in males (27.1% vs. 23.9%; odds ratio [OR]: 1.64). Patients with PAD were older than those without PAD (72.3+/-9.9 years vs. 65.6+/-11.7 years; OR: 1.06), and more frequently had diabetes (43.3% vs. 31.3%; OR: 2.02), coronary heart disease (CHD) (27.0% vs. 18.8%; OR: 1.67), stroke (44.4% vs. 28.3%; OR: 1.78), lipid disorders (57.2% vs. 50.7%; OR: 1.3) and a smoking habit (42.7% vs. 38.6%; OR: 1.52). The ORs for the PAD group compared with the non-PAD group demonstrated that these conditions were inversely related to ABI. Statin, angiotensin-converting enzyme-inhibitors and antiplatelet agents were only used in 40.5%, 53.6% and 69.1% of PAD patients, respectively. The data demonstrated the high prevalence and low treatment of PAD in Chinese patients at high CV risk. A lower ABI was associated with generalized atherosclerosis. Based on these findings, ABI should be a routine measurement in high risk patients. Aggressive medication was required in these patients.

It has been shown that preoperative statin therapy reduces all-cause and cardiovascular mortality in patients undergoing major noncardiac vascular surgery. In this report, we investigated the influence of statin use on early and late outcome following endovascular abdominal aortic aneurysm repair (EVAR). The study population, consisting of patients collated in the EUROSTAR registry, was stratified in two groups according to statin use. Baseline characteristics between the two groups were compared by chi-square and Wilcoxon rank sum tests for discrete and continuous variables. The effects of statin use on outcomes after EVAR were analyzed by multivariate regression models. Of the 5,892 patients enrolled in the EUROSTAR registry, 731 (12.4%) patients used statins for hyperlipidemia. Statin users were younger, were more obese, and had a higher prevalence of diabetes, cardiovascular disease, and hypertension. After 5 years of follow-up, the cumulative survival rate was 77% for nonusers of statin versus 81% for statin users (p = .005). After adjustment for age and other risk factors, statin use was still an independent predictor of improved survival (p = .03). Our results revealed that statin prescription was more frequent in younger patients. However, when adjusted for age and medical risk factors, the use of statin in patients who underwent EVAR was still independently associated with reduced overall mortality.
