Omega-3 polyunsaturated fatty acids (PUFAs) are a key component of a heart-healthy diet. For patients without clinical atherosclerotic cardiovascular disease, 2 or more servings of fatty fish per week is recommended to obtain adequate intake of omega-3 PUFAs. If this not possible, dietary supplementation with an appropriate fish oil may be reasonable. Supplementation with omega-3 PUFA capsules serves 2 distinct but overlapping roles treatment of hypertriglyceridemia and prevention of cardiovascular events. Marine-derived omega-3 PUFAs reduce triglycerides and have pleiotropic effects including decreasing inflammation, improving plaque composition and stability, and altering cellular membranes. Clinical trial data have shown inconsistent results with omega-3 PUFAs improving cardiovascular outcomes. In this paper, the authors provide an overview of PUFAs and a summary of key clinical trial data. Recent trial data suggest the use of prescription eicosapentaenoic acid ethyl ester for atherosclerotic cardiovascular disease event reduction in selected populations.
The mechanisms by which hypertension accelerates coronary artery disease are poorly understood. Patients with hypertension often have confounding humoral changes, and to date, no experimental models have allowed analysis of the isolated effect of pressure on atherosclerosis in a setting that recapitulates the dimensions and biomechanics of human coronary arteries.

This study sought to analyze the effect of pressure on coronary atherosclerosis and explore the underlying mechanisms.

Using inflatable suprarenal aortic cuffs, we increased mean arterial pressure by >30mmHg in the cephalad body part of wild-type and hypercholesterolemic proprotein convertase subtilisin kexin type 9 (PCSK9)
Yucatan minipigs for >1 year. Caudal pressures remained normal.

Under hypercholesterolemic conditions in PCSK9
transgenic minipigs, cephalad hypertension accelerated coronary atherosclerosis to almost 5-fold with consistent development of fibroatheromas that were sufficiently large to cause stenosis on computed of the artery to match increased tensile forces in hypertension alters the passage of macromolecules and leads to increased intimal accumulation of low-density lipoproteins.
Although intensive blood pressure reduction has cardiovascular benefits, the absolute benefit is greater in those at higher cardiovascular disease (CVD) risk.

This study examined whether N-terminal pro-B-type natriuretic peptide (NT-proBNP) helps identify subjects at higher risk for CVD events across systolic blood pressure (SBP), diastolic blood pressure (DBP), or pulse pressure (PP) categories.

Participants from the ARIC (Atherosclerosis Risk In Communities) study visit 4 (1996 to 98) were grouped according to SBP, DBP, or PP categories and further stratified by NT-proBNP categories. Cox regression models were used to estimate hazard ratios for incident CVD (coronary heart disease, ischemic stroke, or heart failure hospitalization) and mortality across combined NT-proBNP and/or BP categories, adjusting for CVD risk factors.

There were 9,309 participants (age 62.6 ± 5.6 years; 58.3% women) with 2,416 CVD events over a median follow-up of 16.7 years. Within each SBP, DBP, or PP category, a higher catevated NT-proBNP had greater cardiovascular risk compared with those with stage 2 SBP but lower NT-proBNP. Future studies are needed to evaluate use of biomarker-based strategies for CVD risk assessment to assist with initiation or intensification of BP treatment.
Infective endocarditis (IE) in people who inject drugs (PWID) is an emergent public health problem.

The purpose of this study was to investigate IE in PWID and compare it with IE in non-PWID patients.

Two prospective cohort studies (ICE-PCS and ICE-Plus databases, encompassing 8,112 IE episodes from 2000 to 2006 and 2008 to 2012, with 64 and 34 sites and 28 and 18 countries, respectively). Outcomes were compared between PWID and non-PWID patients with IE. Logistic regression analyses were performed to investigate risk factors for 6-month mortality and relapses amongst PWID.

A total of 7,616 patients (591 PWID and 7,025 non-PWID) were included. PWID patients were significantly younger (median 37.0 years [interquartile range 29.5 to 44.2 years] vs. 63.3 years [interquartile range 49.3 to 74.0 years]; p<0.001), male (72.5% vs. 67.4%; p=0.007), and presented lower rates of comorbidities except for human immunodeficiency virus, liver disease, and higher rates of prior IE. Amongst IE cases in PWID, 313 (lation.

The long-term clinical benefit after percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) in patients with total occlusions (TOs) and complex coronary artery disease has not yet been clarified.

The objective of this analysis was to assess 10-year all-cause mortality in patients with TOs undergoing PCI or CABG.

This is a subanalysis of patients with at least 1 TO in the SYNTAXES (Synergy Between PCI With Taxus and Cardiac Surgery Extended Survival) study, which investigated 10-year all-cause mortality in the SYNTAX (Synergy Between PCI With Taxus and Cardiac Surgery) trial, beyond its original 5-year follow-up. Patients with TOs were further stratified according to the status of TO recanalization or revascularization.

Of 1,800 randomized patients to the PCI or CABG arm, 460 patients had at least 1 lesion of TO. In patients with TOs, the status of TO recanalization or revascularization was not associated with 10-year all-cause mortality, irrespective of the assigned treatmehe Treatment of Narrowed Arteries [SYNTAX]; NCT00114972).
At 10-year follow-up, the status of TO recanalization or revascularization did not affect mortality, irrespective of the assigned treatment and location of TOs. The present study might support contemporary practice among high-volume chronic TO-PCI centers where recanalization is primarily offered to patients for the management of angina refractory to medical therapy when myocardial viability is confirmed.

Direct oral anticoagulants are administered in fixed doses irrespective of body weight, but guidelines recommend against their use in patients with extremes of body weight.

This study determined the effects of dual-pathway inhibition antithrombotic regimen (rivaroxaban 2.5mg twice daily plus aspirin 100mg/day) compared with aspirin Halone across a range of patient body mass indexes (BMIs) and body weights.

This was a secondary analysis of the COMPASS (Cardiovascular OutcoMes for People using Anticoagulation StrategieS) trial, which included patients with chronic coronary artery disease or peripheral artery disease. Efficacy and safety outcomes were studied in relation to BMI (normal 18.5≤BMI<25kg/m
, overweight 25≤BMI<30kg/m
, obese≥30kg/m
) and body weight (≤70kg, 70< weight≤90kg, and >90kg; as well as≤120kg vs. >120kg).

Among 27,395 randomized patients, 6,459 (24%) had normal BMI, 12,047 (44%) were overweight, and 8,701 (32%) were obese. The combination of rivaroxaban and aspirin cxaban for the Prevention of Major Cardiovascular Events in Coronary or Peripheral Artery Disease [COMPASS]; NCT01776424).
The effects of dual-pathway antithrombotic therapy are consistent irrespective of BMI or body weight, suggesting no need for dose adjustments in the ranges of weights and BMI of patients enrolled in the COMPASS trial. Further studies need to address this problem in relation to greater extremes of body weight.

Cycles of building and mobilizing storage fat are fundamental in (re)distributing lipid substrates between tissues or to progress ontogenetic transitions. In this study, we show that Hormone-sensitive lipase (Hsl) specifically controls SE mobilization to initiate intergenerational sterol transfer in Drosophila melanogaster. Tissue-autonomous Hsl functions in the maternal fat body and germline coordinately prevent adult SE overstorage and maximize sterol allocation to embryos. While Hsl-deficiency is largely dispensable for normal development on sterol-rich diets, animals depend on adipocyte Hsl for optimal fecundity when dietary sterol becomes limiting. Notably, accumulation of SE but not of TG is a characteristic of Hsl-deficient cells across phyla including murine white adipocytes. In summary, we identified Hsl as an ancestral regulator of SE degradation, which improves intergenerational sterol transfer and reproductive success in flies.Lymphocyte numbers need to be quite tightly regulated. It is generally assumed that lymphocyte production and lifespan increase homeostatically when lymphocyte numbers are low and, vice versa, return to normal once cell numbers have normalized. This widely accepted concept is largely based on experiments in mice, but is hardly investigated in vivo in humans. Here we quantified lymphocyte production and loss rates in vivo in patients 0.5-1 year after their autologous hematopoietic stem cell transplantation (autoHSCT). We indeed found that the production rates of most T- and B-cell subsets in autoHSCT-patients were two to eight times higher than in healthy controls, but went hand in hand with a threefold to ninefold increase in cell loss rates. Both rates also did not normalize when cell numbers did. This shows that increased lymphocyte production and loss rates occur even long after autoHSCT and can persist in the face of apparently normal cell numbers.Coupled oscillatory circuits are ubiquitous in nervous systems. Given that most biological processes are temperature-sensitive, it is remarkable that the neuronal circuits of poikilothermic animals can maintain coupling across a wide range of temperatures. Within the stomatogastric ganglion (STG) of the crab, Cancer borealis, the fast pyloric rhythm (~1 Hz) and the slow gastric mill rhythm (~0.1 Hz) are precisely coordinated at ~11°C such that there is an integer number of pyloric cycles per gastric mill cycle (integer coupling). Upon increasing temperature from 7°C to 23°C, both oscillators showed similar temperature-dependent increases in cycle frequency, and integer coupling between the circuits was conserved. Thus, although both rhythms show temperature-dependent changes in rhythm frequency, the processes that couple these circuits maintain their coordination over a wide range of temperatures. Such robustness to temperature changes could be part of a toolbox of processes that enables neural circuits to maintain function despite global perturbations.
