Project description:Reducing plasma levels of low-density lipoprotein cholesterol (LDL-C) remains the cornerstone in the primary and secondary prevention of cardiovascular disease. However, lack of efficacy and adverse effects mean that a substantial proportion of patients fail to achieve acceptable LDL-C levels with currently available lipid-lowering drugs. Over the last decade, inhibition of proprotein convertase subtilisin/kexin type 9 (PCSK9) has emerged as a promising therapeutic strategy to reduce residual cardiovascular disease risk. Binding of PCSK9 to the LDL receptor targets the receptor for lysosomal degradation. The recognition that inhibition of PCSK9 increases LDL receptor activity has led to the development of a number of approaches to directly target PCSK9. Numerous monoclonal antibodies against PCSK9 are currently being evaluated in phase 3 trials, involving various patient categories on different background lipid-lowering therapies. Current evidence shows reductions in LDL-C levels of up to 70 % may be achieved with PCSK9 inhibition, independent of background statin therapy. This review examines the most recent evidence and future prospects for the use of PCSK9 inhibitors in the prevention of cardiovascular disease.
Project description:General lipoprotein (Lp) (a) screening can help to identify patients at high risk for cardiovascular disease. Non-invasive methods allow early detection of clinically asymptomatic incipient atherosclerotic disease. Medical treatment options are still unsatisfactory. Lp(a) apheresis is an established treatment in Germany for secondary prevention of progressive cardiovascular disease. Statin-based lowering of LDL cholesterol and thrombocyte aggregation inhibitors still represent the basis of medical treatment. Target levels for LDL-cholesterol should be modified in patients with hyperlipoproteinemia (a).
Project description:Background We aimed to identify the prevalence of cardiovascular risk factors, and investigate preventive cardiovascular medication use and achievement of targets as per Dutch cardiovascular risk management guidelines among human immunodeficiency virus (HIV)-positive and HIV-negative individuals. Design The design was a cross-sectional analysis within an ongoing cohort study. Methods Data on medication use and cardiovascular disease prevalence were available for 528 HIV-positive and 521 HIV-negative participants. We identified cardiovascular risk factors and applied cardiovascular risk management guidelines, mainly focusing on individuals eligible for (a) primary prevention because of high a priori cardiovascular risk, or for (b) secondary prevention. Results One hundred and three (20%) HIV-positive and 77 (15%) HIV-negative participants were classified as having high cardiovascular risk; 53 (10%) HIV-positive and 27 (5%) HIV-negative participants were eligible for secondary prevention. Of HIV-positive individuals 57% at high cardiovascular risk and 42% of HIV-positive individuals eligible for secondary prevention had systolic blood pressures above guideline-recommended thresholds. Cholesterol levels were above guideline-recommended thresholds in 81% of HIV-positive individuals at high cardiovascular risk and 57% of HIV-positive individuals eligible for secondary prevention. No statistically significant differences were observed between HIV-positive and HIV-negative participants regarding achievement of targets, except for glycaemic control (glycated haemoglobin???53?mmol/mol) among individuals using diabetes medication (90% vs 50%, p?=?0.017) and antiplatelet/anticoagulant use for secondary prevention (85% vs 63%, p?=?0.045), which were both superior among HIV-positive participants. Conclusions Cardiovascular risk management is suboptimal in both HIV-positive and HIV-negative individuals and should be improved.
Project description:BackgroundDiet plays a major role in cardiovascular disease (CVD) risk.ObjectivesTo determine the effectiveness of a Mediterranean-style diet for the primary and secondary prevention of CVD.MethodsWe searched for randomised controlled trials (RCTs) of Mediterranean-style diets in healthy adults and those at increased risk of CVD (primary prevention) and with established CVD (secondary prevention).ResultsThirty RCTs were included, 22 in primary prevention and eight in secondary prevention. Clinical endpoints were reported in two trials where there was moderate quality evidence for a reduction in strokes for primary prevention, and low quality evidence for a reduction in total and CVD mortality in secondary prevention. We found moderate quality evidence of improvement in CVD risk factors for primary prevention and low quality evidence of little or no effect in secondary prevention.ConclusionsThere is still some uncertainty regarding the effects of a Mediterranean-style diet in CVD prevention.
