Differential effects of PCSK9 variants on risk of coronary disease and ischaemic stroke

ConclusionPCSK9 genetic variants that confer life-long lower PCSK9 and LDL-C levels appear to have significantly weaker, if any, associations with risk of IS than with risk of CHD. By contrast, similar proportional reductions in risks of IS and CHD have been observed in randomized trials of therapeutic PCSK9-inhibition. These findings have implications for our understanding of when Mendelian randomization can be relied upon to predict the effects of therapeutic interventions.

Conclusions: This cohort study demonstrates that apo B and the apo B/apo A-I ratio were a significant risk predictor of stroke. Furthermore, the predictive ability of apo B and the apo B/apo A-I ratio in stroke risk was better than routine clinical lipid measurements. Thus, measurements of apolipoproteins have superior clinical utility over traditional lipid measurements in identifying subjects at risk for ischemic stroke.Cerebrovasc Dis

CONCLUSIONS: Multimorbid patients with ACS are at a greater risk for worse outcomes than their nonmultimorbid counterparts. Lack of consistent measurement makes interpretation of the impact of multimorbidity challenging and emphasizes the need for more research on multimorbidity's effects on postdischarge healthcare utilization.

In this study, we applied a well studied prediction model developed on data from five CpG sites, to increase the practicability of these tests. We have determined the biological age of the heart, specifically of the right atrium (RA) and left atrium (LA), and of peripheral blood leucocytes, by measuring the mitotic telomere length (TL) and the non-mitotic epigenetic age (DNAmAge). We found that DNAmAge, of both atrial tissues (RA and LA), was younger in respect to the chronological age (-12 years). Furthermore, no significant difference existed between RA and LA, suggesting that, although anatomically diverse and ex...

Triglyceride (TG) to high-density lipoprotein cholesterol (HDL-C) ratio may play a role in predicting cardiovascular events. We aimed to prospectively explore the association between the TG/HDL-C ratio and atherosclerotic cardiovascular disease (ASCVD), ischemic stroke, as well as coronary heart disease (CHD) in a Chinese population.

Worldwide, dyslipidemias are one of the leading causes of cardiovascular disease, mainly coronary heart disease [1]. Dyslipidemias are also associated with an increased risk of ischemic stroke [2]. Dyslipidemias embrace a wide constellation of lipid and lipoprotein abnormalities. Lipoproteins bind lipids and are involved in their transport. Lipid abnormalities include high serum concentrations of low-density lipoprotein (LDL) cholesterol (LDL-C) and/or triglycerides and/or low concentrations of high-density lipoprotein (HDL) cholesterol (HDL-C).

Aberrant epigenetic changes may result from alterations in enzymatic activities, which are responsible for putting in and/or out the covalent groups, altering the epigenome and then modulating gene expression. The identification of novel individual epigenetic-sensitive trajectories at single cell level might pro...

Conclusions: History of stroke and smoking, renal insufficiency, and low HDL-C are independent risk factors for PIS. It is feasible to assess the risk of stroke in preoperative patients using PCE in clinical practice. PMID: 31903867 [PubMed - as supplied by publisher]

AbstractPurpose of ReviewTo review randomized interventional clinical and imaging trials that support lower targeted atherogenic lipoprotein cholesterol goals in “extreme” and “very high” atherosclerotic cardiovascular disease (ASCVD) risk settings. Major atherosclerotic cardiovascular event (MACE) prevention among the highest risk patients with ASCVD requires aggressive management of global risks, including lowering of the fundamental atherogenic ap olipoprotein B-associated lipoprotein cholesterol particles [i.e., triglyceride-rich lipoprotein remnant cholesterol, low-density lipoprotein cholester...

In this study, researchers studied 438,952 participants in the UK Biobank, who had a total of 24,980 major coronary events - defined as the first occurrence of non-fatal heart attack, ischaemic stroke, or death due to coronary heart disease. They used an approach called Mendelian randomisation, which uses naturally occurring genetic differences to randomly divide the participants into groups, mimicking the effects of running a clinical trial. People with genes associated with lower blood pressure, lower LDL cholesterol, and a combination of both were put into different groups, and compared against those without thes...
