What are effective medication combinations for dyslipidemia?
Many combination drug therapies are effective in treating dyslipidemia. Compared with statin monotherapy, combinations that include ezetimibe (Zetia), a bile acid sequestrant, or niacin further lower low- density lipoprotein (LDL) cholesterol (strength of recommendation [SOR]: A), and increase the likelihood of attaining National Cholesterol Education Program (NCEP) LDL cholesterol goals (SOR: B). Adding ezetimibe to a bile acid sequestrant reduces LDL cholesterol (SOR: B). Fibrate or niacin added to statin monotherapy provide mixed lipid-modifying effects for combined dyslipidemia (SOR: A)
Integrated guidance on the care of familial hypercholesterolaemia from the International FH Foundation
Assessing compliance of cardiologists with the national cholesterol education program (NCEP) III guidelines in an ambulatory care setting
INTRODUCTION: The NCEP III -ATP guidelines provide clear clinical directives for lipid management especially statins therapy in appropriate patient groups. Compliance of primary care physicians with these guidelines especially in ambulatory care settings has been shown to be poor. The compliance of cardiologist to these guidelines is less documented. METHODS: A retrospective chart review of 386 patients managed in a large urban cardiology practice was undertaken. Patients with documented contraindications to use of statins were excluded from the study. Only patients with two or more years of follow-up in the practice were included. Demographic variables and medical history including CAD or its equivalent and its major risk factors were identified. The proportion of patients on statins and adequacy of statins therapy were recorded. The lipid profiles of all patients were also analyzed. RESULTS: Fifteen patients with documented contraindications to statins therapy including persistent/severe LFT abnormalities, allergies, and gastrointestinal intolerance were excluded. A total of 371 patients were included in the analysis. The mean age for patients in the study was 65 years (range: 42–84). 236 (64%) were males while 141 (36%) were females. 161 (43%) patients were on statins while 210 (57%) weren't. 88 (62%) of females were on stain compared to 116 (49%) of males (p = 0.001). 68% of patients below the age of 50 yrs were not on statins compared with 55% of those greater than 50 yrs (p = 0.01). 38% of patients on statins therapy had sub-optimal lipid profile despite greater than two years of therapy. No statistically significant differences in race and use of satins were noted. CONCLUSION: This study demonstrates a higher than expected prevalence of sub-optimal management of dyslipidemia among patients with established coronary heart disease without contraindications to statins managed by cardiologists. Cardiology and primary care practices require similar comprehensive routine lipid management program that is assiduously maintained and evaluated at both in-patient and out patient settings to ensure most patients receive optimal therapy with statins and other lipid lowering agents
Complementary Therapy to Target LDL Cholesterol: The Role of the Ezetimibe/Simvastatin Combination
Cardiovascular (CV) disease remains the number 1 cause of death in the USA. Nonetheless, there has been a decline in the age-adjusted death rate for coronary heart disease (CHD) which may be due to more aggressive treatment guidelines for treating CV risk factors, such as hypertension, diabetes, and dyslipidemia. The recent update to the National Cholesterol Education Program (NCEP) guidelines have recommended lower low-density lipoprotein cholesterol (LDL-C) goals in high-risk patients. Based on the new targets for LDL-C, clinicians will need more efficacious lipid-lowering therapies. One of these newer therapies is the combination of ezetimibe and simvastatin. This article reviews the implications of the updated guidelines and discusses the efficacy and safety of ezetimibe/simvastatin for lowering LDL-C
The Correlation of Dyslipidemia with the Extent of Coronary Artery Disease in the Multiethnic Study of Atherosclerosis.
BackgroundThe extent of coronary artery calcium (CAC) improves cardiovascular disease (CVD) risk prediction. The association between common dyslipidemias (combined hyperlipidemia, simple hypercholesterolemia, metabolic Syndrome (MetS), isolated low high-density lipoprotein cholesterol, and isolated hypertriglyceridemia) compared with normolipidemia and the risk of multivessel CAC is underinvestigated.ObjectivesTo determine whether there is an association between common dyslipidemias compared with normolipidemia, and the extent of coronary artery involvement among MESA participants who were free of clinical cardiovascular disease at baseline.MethodsIn a cross-sectional analysis, 4,917 MESA participants were classified into six groups defined by specific LDL-c, HDL-c, or triglyceride cutoff points. Multivessel CAC was defined as involvement of at least 2 coronary arteries. Multivariate Poisson regression analysis evaluated the association of each group with multivessel CAC after adjusting for CVD risk factors.ResultsUnadjusted analysis showed that all groups except hypertriglyceridemia had statistically significant prevalence ratios of having multivessel CAC as compared to the normolipidemia group. The same groups maintained statistical significance prevalence ratios with multivariate analysis adjusting for other risk factors including Agatston CAC score [combined hyperlipidemia 1.41 (1.06-1.87), hypercholesterolemia 1.55 (1.26-1.92), MetS 1.28 (1.09-1.51), and low HDL-c 1.20 (1.02-1.40)].ConclusionCombined hyperlipidemia, simple hypercholesterolemia, MetS, and low HDL-c were associated with multivessel coronary artery disease independent of CVD risk factors and CAC score. These findings may lay the groundwork for further analysis of the underlying mechanisms in the observed relationship, as well as for the development of clinical strategies for primary prevention
The Epidemiological and Clinical Characteristics of Patients Admitted for Coronary Angiography to Evaluate Ischemic Heart Disease
Study of drug utilization, morbidity pattern and cost of hypolipidemic agents in a tertiary care hospital
Background: Data on the extent of use and costs of lipid-lowering agents are not widely available. Our aim was to study the drug utilization and morbidity pattern, cost of different hypolipidemic drugs along with the risk assessment for coronary heart disease.Methods: After approval of protocol by the Institutional Review Board, an observational, prospective study was carried out in 300 patients using NCEP and ATP III Guidelines-2002 for evaluation of presence or absence of risk factors for coronary heart diseases. Data were analysed using SPSS software version 16.0and WHO Core Drug Prescribing Indicators.Results: Patient’s morbidity pattern revealed that 62%, 49.3%, 28% suffered from ischemic heart disease, hypertension and type 2 diabetes mellitus respectively. On risk assessment, 48%, 13.3% patients had borderline and high level of total cholesterol respectively; 42%, 22.7% had borderline and high triglyceride levels respectively; 71.1% men and 62% women had low HDL cholesterol levels while 17.3%, 6% and 2.7% patients had borderline high, high and very high level of LDL cholesterol levels respectively. Frequency of prescriptions was atorvastatin (82%), rosuvastatin (9.3%) and simvastatin (4.7%) among the most frequently prescribed statins drug group. The mean number of drugs per prescription was 7.34. Drugs prescribed by generic name and from essential drugs list was 24.96% and 71.81% respectively. Mean cost of hypolipidemic agents/prescription/day was 10.74 (±1.96) Indian Rupees with rosuvastatin being the costliest.Conclusion: Rational use of hypolipidemic agents with an increasing trend of statins prescriptions will significantly reduce the morbidity and mortality from coronary heart diseases.
Preimplantation biopsy predicts delayed graft function, glomerular filtration rate and long-term graft survival of transplanted kidneys
Background
The predictive value of preimplantation biopsies for long-term graft function is often limited by conflicting results. The aim of this study was to evaluate the influence of time-zero graft biopsy histological scores on early and late graft function, graft survival and patient survival, at different time points.
Methods
We retrospectively analyzed 284 preimplantation biopsies at a single center, in a cohort of recipients with grafts from live and deceased donors (standard and nonstandard), and their impact in posttransplant renal function after a mean follow-up of 7 years (range 1–16). Implantation biopsy score (IBS), a combination score derived from 4 histopathological aspects, was determined from each sample. The correlation with incidence of delayed graft function (DGF), creatinine clearance (1st, 3rd and 5th posttransplant year) and graft and patient survival at 1 and 5 years were evaluated.
Results
Preimplantation biopsies provided somewhat of a prognostic index of early function and outcome of the transplanted kidney in the short and long term. In the immediate posttransplantation period, the degree of arteriolosclerosis and interstitial fibrosis correlated better with the presence of DGF. IBS values between 4 and 6 were predictive of worst renal function at 1st and 3rd years posttransplant and 5-year graft survival. The most important histological finding, in effectively transplanted grafts, was the grade of interstitial fibrosis. Patient survival was not influenced by IBS.
Conclusions
Higher preimplantation biopsy scores predicted an increased risk of early graft losses, especially primary nonfunction. Graft survival (at 1st and 5th years after transplant) but not patient survival was predicted by IBS
Prevalence of the metabolic syndrome in Chinese adolescents
Since national figures on the occurrence of metabolic syndrome among Chinese adolescents are lacking, this study aims to estimate its prevalence and distribution among Chinese youngsters. The 2002 China National Nutrition and Health Survey is a nationally representative cross-sectional study. Applying the criteria for US adolescents, we estimated the prevalence of metabolic syndrome among 2761 adolescents aged 15 to 19 years. The prevalence of metabolic syndrome among Chinese adolescents overall was 3·7% (10% in US adolescents). It was 35·2 %, 23·4% and 2·3% among adolescents who were overweight (BMI 85th percentile and one or two parent(s) with metabolic syndrome, the prevalence was 46·4 %. A total of 96% of overweight adolescents had at least one and 74·1% overweight adolescents had at least two abnormalities of metabolic syndrome. Based on these figures, it is estimated that more than three million Chinese adolescents have metabolic syndrome. Both overweight and metabolic syndrome prevalence among adolescents are still relatively low in China, but the prevalence of metabolic syndrome among Chinese overweight adolescents is similar to those living in the USA
