Key Themes in the Care of Inflammatory Bowel Diseases Among Immigrant Populations: A Systematic Review.

The care of inflammatory bowel disease (IBD) requires special attention among immigrants due to different disease incidence, phenotype, and risk profiles. We aimed to highlight key themes among existing literature to inform equitable care in all immigrants living with IBD. A systematic literature search was conducted in MEDLINE, EMBASE, the Cochrane library, Scopus, and ProQuest from inception to February 2023 to identify studies capturing the care of IBD among immigrants who moved from one country to another, irrespective of the timing of IBD diagnosis. Studies on immigrant children and children of immigrants were also included. We reported qualitative and quantitative data as reported in each individual study, and where applicable, we noted comparisons between immigrants and non-immigrants, defined as natives of the adopted country. This review included 50 eligible studies. 12/19 (63.1%) studies reported lower incidence of IBD among immigrants, although rates increased from first- to second-generation immigrants in five studies. Most immigrants had significant changes in their diet after immigration, and their gut microbiota was different compared to non-immigrants. Immigrants had different environmental exposures and in certain populations, more severe IBD phenotypes and extra-intestinal manifestations (EIMs). Medical and surgical treatments were lower among immigrants in certain regions, although they had appropriate healthcare utilization and similar hospitalization rates compared to non-immigrants. IBD care among immigrants is unique due to their different risk profiles and disease phenotypes, and the potential barriers with healthcare access. Understanding IBD among immigrants is key to ensure equitable care in this unique population.

Evaluating pathogenicity of variants of unknown significance in APP, PSEN1, and PSEN2.

Autosomal dominant Alzheimer's disease (ADAD) is driven by rare variants in APP, PSEN1, and PSEN2. Although more than 200 pathogenic variants in these genes are known to cause ADAD, other variants are benign, may act as risk factors, or may even reduce Alzheimer's disease risk (e.g. protective). Classifying novel variants in APP, PSEN1, or PSEN2 as pathogenic, risk, benign, or protective is a critical step in evaluating disease risk profiles which further impacts eligibility for clinical trials focused on the ADAD population. Here, we classify 53 novel variants in APP, PSEN1, and PSEN2 based on bioinformatic data and cell-based assays. We identified 6 benign variants, 2 risk variants, and 32 likely pathogenic variants. Thirteen variants were associated with reduced Aβ levels in cell-based assays, consistent with a potential protective effect. Together, this study highlights the complexities associated with classification of rare variants in ADAD genes.

Long-Term Outcomes in ICD: All-Causes Mortality and First Appropriate Intervention in Ischemic and Nonischemic Etiologies

Real-life data comparing the long-term outcome in patients with different heart diseases carrying an implantable cardioverter defibrillator (ICD) are scarce. This study aimed to compare the long-term risk of the first appropriate ICD intervention and overall survival in patients with ICD and heart disease of different etiologies. Patients with an ICD implanted between January 1, 2010, and December 31, 2022, followed in our center were included. Study outcomes were all-cause mortality and first appropriate ICD intervention. A comparison between ischemic heart disease (IHD) and non-IHD (NIHD) was performed. In NIHD different etiologies of dilated cardiomyopathy (DCM) were analyzed. Overall, 1184 patients (592 IDH; 592 NIHD) were included. During a median follow-up of 53 months all-cause death occurred in 399 patients (34%) whereas first appropriate ICD intervention occurred in 320 (27%). All-cause mortality was significantly higher in IHD vs NIHD patients (60% vs 43%; p <0.0001) but no differences in appropriate ICD intervention rate at 10 years (34% vs 40%; p = 0.125) were observed. In patients with NIHD, a higher 10-year mortality rate was found in valvular heart disease, post-radio/chemotherapy DCM (rctDCM), and hypertensive DCM. Hypertrophic cardiomyopathy, alcoholic DCM, and rctDCM were the least arrhythmic phenotypes in NIHD. Of note, inappropriate interventions in alcoholic DCM and rctDCM were higher than appropriate ones. In conclusion, the rate of ICD-appropriate interventions and mortality is different according to the etiology of heart disease and cardiovascular risk profile; this should be taken into consideration in the prognostic stratification of these patients at the time of implantation.

Precognition of Known And Unknown Biothreats: A Risk-Based Approach.

Data mining and artificial intelligence algorithms can estimate the probability of future occurrences with defined precision. Yet, the prediction of infectious disease outbreaks remains a complex and difficult task. This is demonstrated by the limited accuracy and sensitivity of current models in predicting the emergence of previously unknown pathogens such as Zika, Chikungunya, and SARS-CoV-2, and the resurgence of Mpox, along with their impacts on global health, trade, and security. Comprehensive analysis of infectious disease risk profiles, vulnerabilities, and mitigation capacities, along with their spatiotemporal dynamics at the international level, is essential for preventing their transnational propagation. However, annual indexes about the impact of infectious diseases provide a low level of granularity to allow stakeholders to craft better mitigation strategies. A quantitative risk assessment by analytical platforms requires billions of near real-time data points from heterogeneous sources, integrating and analyzing univariable or multivariable data with different levels of complexity and latency that, in most cases, overwhelm human cognitive capabilities. Autonomous biosurveillance can open the possibility for near real-time, risk- and evidence-based policymaking and operational decision support.

Beyond LDL-C: unravelling the residual atherosclerotic cardiovascular disease risk landscape-focus on hypertriglyceridaemia.

Historically, atherosclerotic cardiovascular disease (ASCVD) risk profile mitigation has had a predominant focus on low density lipoprotein cholesterol (LDL-C). In this narrative review we explore the residual ASCVD risk profile beyond LDL-C with a focus on hypertriglyceridaemia, recent clinical trials of therapeutics targeting hypertriglyceridaemia and novel modalities addressing other residual ASCVD risk factors. Hypertriglyceridaemia remains a significant ASCVD risk despite low LDL-C in statin or proprotein convertase subtilisin/kexin type 9 inhibitor-treated patients. Large population-based observational studies have consistently demonstrated an association between hypertriglyceridaemia with ASCVD. This relationship is complicated by the co-existence of low high-density lipoprotein cholesterol. Despite significantly improving atherogenic dyslipidaemia, the most recent clinical trial outcome has cast doubt on the utility of pharmacologically lowering triglyceride concentrations using fibrates. On the other hand, purified eicosapentaenoic acid (EPA), but not in combination with docosahexaenoic acid (DHA), has produced favourable ASCVD outcomes. The outcome of these trials suggests alternate pathways involved in ASCVD risk modulation. Several other pharmacotherapies have been proposed to address other ASCVD risk factors targeting inflammation, thrombotic and metabolic factors. Hypertriglyceridaemia poses a significant residual ASCVD risk in patients already on LDL-C lowering therapy. Results from pharmacologically lowering triglyceride are conflicting. The role of fibrates and combination of EPA and DHA is under question but there is now convincing evidence of ASCVD risk reduction with pure EPA in a subgroup of patients with hypertriglyceridaemia. Clinical guidelines should be updated in line with recent clinical trials evidence. Novel agents targeting non-conventional ASCVD risks need further evaluation.

Impact of Complex Anatomy and Patient Risk Profile in Minimally Invasive Mitral Valve Surgery

BackgroundWe aimed to assess the impact of complex mitral valve disease and patient risk profile on operative outcomes in the large cohort of the Mini-Mitral International Registry. MethodsPatients were assigned to categories of complex degenerative mitral valve regurgitation (DMR; bileaflet or anterior mitral leaflet prolapse/flail) and simple DMR (posterior mitral leaflet prolapse/flail). Subgroup analyses was performed in low-risk (EuroSCORE II <8%) and high-risk (EuroSCORE II >8%) cohorts. A logistic regression model was applied to investigate the impact of valve anatomy and patient risk factors on valve repair rate and operative risk. ResultsThe study cohort consisted of 4524 patients with DMR (complex DMR, 1296; simple DMR, 3228). Valve repair rate was 87.3% and 91% in complex DMR and simple DMR, respectively. Predictors of valve replacement were anterior leaflet prolapse/flail, bileaflet flail, female sex, age, and reoperation, whereas Barlow disease was protective. Clinical results were comparable between complex DMR and simple DMR. On subgroup analyses, high-risk patients showed less satisfactory outcomes with respect to both the valve repair and operative mortality rates. ConclusionsOur findings suggest that complex DMR can be satisfactorily addressed by minimally invasive techniques. However, whereas complex disease was associated with low operative risk, anterior leaflet lesions and bileaflet flail remain negative predictors of successful valve repair. Conversely, valve repair rate was less satisfactory in high-risk patients, regardless of DMR complexity.

Analysis of the Relationship between Atherosclerosis Cardiovascular Disease Risk Profile and Occupational Profile to the WHO Cardiovascular Risk Chart 2019 for South-East Asia in Oil and Gas Industry.

The World Health Organization (WHO) has launched a new 10-year cardiovascular risk prediction recommendation known as the WHO Cardiovascular Risk Chart 2019 (WHO CRC). However, there is currently no assessment available regarding the relationship between ASCVD classic and occupational profiles to WHO CRC, specifically in occupational settings and in the context of the Indonesian Heart Association's (IHA) adjusted version of the WHO CRC for South-East Asia (WHO CRC-INA). This study aims to fill this gap by examining the relationship between classic (Atherosclerosis Cardiovascular Disease) ASCVD and occupational profiles within the oil and gas industry, specifically the WHO CRC-INA. This study is analytical cross-sectional research data were analyzed using the Chi-square test and logistic regression, with a significance level of P < 0.05. The research using total sampling method amounted to 240 workers from January to May 2022 of Medical Check Up (MCU) in a major oil and gas company. The ASCVD risk measurement instrument uses the final score of the WHO CRC-INA, grouped into low- and medium-high risk. Analysis showed that occupational profiles had a relationship with WHO CRC-INA medium-high risk, as seen in the bivariate analysis for shift work and work type (P = 0.018; OR = 2,045) had a relationship with WHO CRC-INA medium-high risk.

Assessing Cardiovascular Health in Paediatric Hypertrophic Cardiomyopathy Using the CANHEART Health Index

BackgroundPaediatric hypertrophic cardiomyopathy (HCM) is associated with sudden cardiac death, often resulting in restriction of strenuous physical activity. High levels of inactivity and a rise in youth obesity may increase risk of poor cardiovascular (CV) health in these patients. We aim to compare the CV disease risk profile of paediatric patients with HCM to Canadian youth. MethodsPatients with HCM (10-19 years) were recruited from 10 paediatric cardiac centres in Canada. The CV disease risk profile was determined using the Healthy Hearts School Program questionnaire and Cardiovascular Health in Ambulatory Care Research Team (CANHEART) health index. Poisson regressions were used to assess associations between the CV disease risk profile of paediatric patients with HCM and the overall CANHEART health score. ResultsA total of 56 subjects were enrolled (71% male, median age: 15.5 years [interquartile range: 13.8-16.8], median body mass index: 23.3 [interquartile range: 19.5-27.7]). Results of the CANHEART health index revealed that 89% of participants with HCM never tried smoking, 52% had a healthy body mass index, 39% consumed ≥5 fruits/vegetables per day, and 50% engaged in ≥60 minutes of walking or 20 minutes of running/jogging per day. When CANHEART intermediate and poor health index scores were combined, similar proportions were obtained for each group (HCM 82.1% vs Canadian youth 83.4%; P = 0.724). ConclusionsMany paediatric patients with HCM in Canada have intermediate or poor CV health as determined by the CANHEART health score, with high rates of obesity and low physical activity levels driving these trends. Interventions should be developed to promote positive CV health behaviours among patients with HCM.

An Evaluation of DNA Methylation Levels and Sleep in Relation to Hot Flashes: A Cross-Sectional Study.

Objectives: We aimed to evaluate the DNA methylation levels in perimenopausal and postmenopausal women, measured through Long Interspersed Element-1 (LINE-1) and Alu, and the sleep parameters in relation to the presence of hot flashes (HFs). Methods: This cross-sectional study included 30 peri- or postmenopausal women aged between 45 and 55. The menopausal status was determined according to STRAW + 10 criteria and all participants had a low cardiovascular disease (CVD) risk profile determined by Framingham risk score. The sample was divided into two groups based on the presence or absence of HFs documented in their medical history during their initial visit: Group 1 (n = 15) with HFs present and Group 2 (n = 15) with HFs absent. The patients had polysomnography test and HFs were recorded both by sternal skin conductance and self-report overnight. Genomic DNA was extracted from the women's blood and methylation status was analyzed by fluorescence-based real-time quantitative PCR. The quantified value of DNA methylation of a target gene was normalized by β-actin. The primary outcome was the variation in methylation levels of LINE-1 and Alu and sleep parameters according to the presence of HFs. Results: LINE-1 and Alu methylation levels were higher in Group 1 (HFs present), although statistically non-significant. LINE-1 methylation levels were negatively correlated with age. Sleep efficiency was statistically significantly lower for women in Group 1 (HFs present) (74.66% ± 11.16% vs. 82.63% ± 7.31%; p = 0.03). The ratio of duration of awakening to total sleep time was statistically significantly higher in Group 1 (HFs present) (22.38% ± 9.99% vs. 15.07% ± 6.93, p = 0.03). Objectively recorded hot flashes were significantly higher in Group 1 (4.00 ± 3.21 vs. 1.47 ± 1.46, p = 0.03). None of the cases in Group 2 self-reported HF despite objectively recorded HFs during the polysomnography. The rate of hot flash associated with awakening was 41.4% in the whole sample. Conclusions: Women with a history of hot flashes exhibited lower sleep efficiency and higher awakening rates. Although a history of experiencing hot flashes was associated with higher LINE-1 and Alu methylation levels, no statistical significance was found. Further studies are needed to clarify this association. This study was funded by the Scientific Research Projects Coordination Unit of Istanbul University-Cerrahpasa. Project number: TTU-2021-35629.

Antenatal Glycemic Management and Postpartum Cardiovascular Disease Risk Screening

ObjectivesThis study aims to evaluate the cardiovascular disease (CVD) risk profiles of patients referred to the Maternal Health Clinic (MHC) with a history of gestational diabetes mellitus (GDM). MethodsEligible patients had their MHC appointment at 6 months postpartum between November 2011 and May 2022 and experienced GDM in their most recent pregnancy. Included participants were then divided into subgroups comparing methods of glycemic control: diet-controlled GDM and insulin-controlled GDM. Additionally, the MHC recruited 47 patients who have not experienced a complication in pregnancy to act as a comparator group in research studies. Demographics, medical and pregnancy history, and CVD risk scores were compared between the 3 groups. ResultsIn total, 344 patients with GDM were included in the analysis; 165 were insulin-controlled and 179 diet-controlled. When measuring the median 30-year Framingham risk score based on both BMI and lipids, there was a significant stepwise increase seen from the unexposed group, the diet-controlled GDM, and the insulin-controlled groups, respectively (all P < 0.05). The presence of metabolic syndrome showed a stepwise increase in prevalence when comparing the unexposed group, diet-exposure group, and the insulin-exposure group, respectively (16.7%; 21.5%–44.8%, P < 0.05). ConclusionsOur findings reinforce the prevalence of maternal CVD risk among GDM-diagnosed patients in the postpartum period and the necessity for screening. More specifically, our findings show how CVD risk may differ based on required interventions for glycemic control throughout pregnancy. Future research should aim to compare a more diverse patient population to optimise the generalizability of glycemic control-specific CVD outcomes.

Sudden Cardiac Death Risk Stratification in Heart Failure With Preserved Ejection Fraction.

Heart failure with preserved ejection fraction (HFpEF) poses a significant clinical challenge, with sudden cardiac death (SCD) emerging as one of the leading causes of mortality. Despite advancements in cardiovascular medicine, predicting and preventing SCD in HFpEF remains complex due to multifactorial pathophysiological mechanisms and patient heterogeneity. Unlike heart failure with reduced ejection fraction, where impaired contractility and ventricular remodeling predominate, HFpEF pathophysiology involves heavy burden of comorbidities such as hypertension, obesity, and diabetes. Diverse mechanisms, including diastolic dysfunction, microvascular abnormalities, and inflammation, also contribute to distinct disease and SCD risk profiles. Various parameters such as clinical factors and electrocardiogram features have been proposed in SCD risk assessment. Advanced imaging modalities and biomarkers offer promise in risk prediction, yet comprehensive risk stratification models specific to HFpEF ar0e lacking. This review offers recent evidence on SCD risk factors and discusses current therapeutic strategies aimed at reducing SCD risk in HFpEF.

Cardiometabolic Differences in People Living with HIV Receiving Integrase Strand Transfer Inhibitors Compared to Non-nucleoside Reverse Transcriptase Inhibitors: Implications for Current ART Strategies.

In people living with HIV (PLHIV), integrase strand transfer inhibitors (INSTIs) are part of the first-line combination antiretroviral therapy (cART), while non-nucleoside reverse transcriptase inhibitor (NNRTI)-based regimens are alternatives. Distinct cART regimens may variably influence the risk for non-AIDS comorbidities. We aimed to compare the metabolome and lipidome of INSTI and NNRTI-based regimens. The 2000HIV study includes asymptomatic PLHIV (n = 1646) on long-term cART, separated into a discovery cohort with 730 INSTI and 617 NNRTI users, and a validation cohort encompassing 209 INSTI and 90 NNRTI users. Baseline plasma samples from INSTI and NNRTI users were compared using mass spectrometry-based untargeted metabolomic (n = 500) analysis. Perturbed metabolic pathways were identified using MetaboAnalyst software. Subsequently, nuclear magnetic resonance spectroscopy was used for targeted lipoprotein and lipid (n = 141) analysis. Metabolome homogeneity was observed between the different types of INSTI and NNRTI. In contrast, higher and lower levels of 59 and 45 metabolites, respectively, were found in the INSTI group compared to NNRTI users, of which 77.9% (81/104) had consistent directionality in the validation cohort. Annotated metabolites belonged mainly to 'lipid and lipid-like molecules', 'organic acids and derivatives' and 'organoheterocyclic compounds'. In pathway analysis, perturbed 'vitamin B1 (thiamin) metabolism', 'de novo fatty acid biosynthesis', 'bile acid biosynthesis' and 'pentose phosphate pathway' were detected, among others. Lipoprotein and lipid levels in NNRTIs were heterogeneous and could not be compared as a group. INSTIs compared to individual NNRTI types showed that HDL cholesterol was lower in INSTIs compared to nevirapine but higher in INSTIs compared to doravirine. In addition, LDL size was lower in INSTIs and nevirapine compared to doravirine. NNRTIs show more heterogeneous cardiometabolic effects than INSTIs, which hampers the comparison between these two classes of drugs. Targeted lipoproteomic and lipid NMR spectroscopy showed that INSTI use was associated with a more unfavorable lipid profile compared to nevirapine, which was shifted to a more favorable profile for INSTI when substituting nevirapine for doravirine, with evidently higher fold changes. The cardiovascular disease risk profile seems more favorable in INSTIs compared to NNRTIs in untargeted metabolomic analysis using mass-spectrometry.

Relation to Social Determinants in Cardiovascular Disease Risk Profile: An Alarming View

Globally, Cardiovascular disease (CVD) is one of the major reasons for mortality. Cardiovascular health in children and adults is profoundly affected by the milieu of early life. Currently, CVD is taking a different turn based on social antecedents like poverty, the difference in socio-economic status, gender inequality, being a fluid person, and work life in harmony increases the risk of getting into CVD, that too in vulnerable populations like racial and ethnic minorities, women, the elderly, the chronically ill individual with disabilities, lesbian, gay, bisexual, transgender, queer and racism play a significant role in conditioning disease burden and modulating outcomes of CVD. People with low socioeconomic status increase the hypothalamic pituitary adrenal axis (HPA axis) in the body, due to stress response, and at the end, increased cortisol and sympathetic nervous system activity lead to decreased angiogenic activity. People from low socioeconomic backgrounds, loneliness, and social isolation in many cases like racism, ethnic minorities, children, women, elderly, and chronically ill individuals with disabilities, are exposed to constant stress because of a lack of their fundamental needs. The wider introduction of universal screening for social factors that impact cardiac health will help to identify children and families at risk. Hence,aggressive screening tests beginning at an early age will be beneficial for early detection and treatment. Healthcare professionals need to pay attention to promotinghealth education and awareness aids to decrease CVD-associated mortality.

Primary aldosteronism and cardiovascular risk. Review

Primary aldosteronism (PA), a significant and curable cause of secondary hypertension, occurs in 5—10% of hypertensive patients, with prevalence dependent on the severity of hypertension. The main etiologies of PA include bilateral idiopathic hypertrophy (BIH) and aldosterone‑producing adenoma (APA), while less common causes include unilateral hyperplasia, familial hyperaldosteronism (FH) types I—IV, aldosterone‑producing carcinoma, and ectopic aldosterone synthesis. This condition, characterized by excessive secretion of aldosterone, leads to increased reabsorption of sodium and water along with potassium loss, culminating in the distinct clinical signs of elevated aldosterone, suppressed renin, and hypertension. It should be noted that hypokalemia is present in only 28% of patients with PA and is not the main indicator. The association of PA with an increased risk profile for cardiovascular disease, regardless of blood pressure level, is notable. Patients with PA show an increased rate of cardiovascular events compared to patients with essential hypertension, adjusted for age, sex, and blood pressure level. Despite its prevalence, PA often remains undiagnosed, highlighting the need for enhanced screening protocols. The diagnostic process for PA involves a three‑pronged assessment: the aldosterone/renin ratio (ARR) as the initial screening tool, followed by confirmatory and subtype tests. A positive ARR requires confirmatory testing to rule out false positives. Examination to detect PA should be carried out in patients with arterial hypertension: moderate (&gt; 160—179/100—109 mm Hg) or severe (&gt; 180/110 mm Hg); resistant to treatment; with idiopathic or diuretic‑induced hypokalemia; with an accidentally diagnosed tumor of the adrenal glands; if first‑generation relatives are diagnosed with PA, or family history indicates early onset of arterial hypertension, or cerebrovascular disorders at a young age (&lt; 40 years); with accompanying obstructive sleep apnea.

The association of appendicular lean mass and grip strength with low-density lipoprotein, very low-density lipoprotein, and high-density lipoprotein particle diameter: a Mendelian randomization study of the UK Biobank cohort

Abstract Aims Reduced muscle mass and reduced strength are frequently associated with both alterations in blood lipids and poorer cardiometabolic outcomes in epidemiological studies; however, a causal association cannot be determined from such observations. Two-sample Mendelian randomization (MR) was applied to assess the association of genetically determined appendicular lean mass (ALM) and handgrip strength (HGS) with serum lipid particle diameter. Methods and results Mendelian randomization was implemented using summary-level data from the largest genome-wide association studies on ALM (n = 450 243), HGS (n = 223 315), and lipoprotein [low-density lipoprotein (LDL), very LDL (VLDL), and high-density lipoprotein (HDL)] particle diameters (n = 115 078). Inverse variance-weighted (IVW) method was used to calculate the causal estimates. Weighted median-based method, MR-Egger, and leave-one-out method were applied as sensitivity analysis. Greater ALM had a statistically significant positive effect on HDL particle diameter (MR-Egger: β = 0.055, SE = 0.031, P = 0.081; IVW: β = 0.068, SE = 0.014, P &amp;lt; 0.001) and a statistically significant negative effect on VLDL particle diameter (MR-Egger: β = −0.114, SE = 0.039, P = 0.003; IVW: β = −0.081, SE = 0.017, P &amp;lt; 0.001). Similarly, greater HGS had a statistically significant positive effect on HDL particle diameter (MR-Egger: β = 0.433, SE = 0.184, P = 0.019; IVW: β = 0.121, SE = 0.052, P = 0.021) and a statistically significant negative effect on VLDL particle diameter (MR-Egger: β = −0.416, SE = 0.163, P = 0.011; IVW: β = −0.122, SE = 0.046, P = 0.009). There was no statistically significant effect of either ALM or HGS on LDL particle diameter. Conclusion There were potentially causal associations between both increasing ALM and HGS and increasing HDL particle size and decreasing VLDL particle size. These causal associations may offer possibilities for interventions aimed at improving cardiovascular disease risk profile.

Sex Differences in Outcomes of Adults With Isolated Coarctation of the Aorta

BackgroundData are limited about the effect (or lack thereof) of sex on clinical outcomes in adults with coarctation of the aorta (COA). The purpose of this study was to compare atherosclerotic cardiovascular disease (ASCVD) risk profile, blood pressure (BP) data, echocardiographic indices, and mortality between men and women with COA. MethodsRetrospective study of adults with COA, and no associated left-sided obstructive lesions, who received care at Mayo Clinic (2003-2022). ASCVD risk profile was assessed as the prevalence of hypertension, hyperlipidemia, type 2 diabetes, obesity, smoking history, and coronary artery disease. A 24-hour BP monitor was used to assess daytime and nighttime BP and calculate nocturnal dipping. ResultsOf 621 patients with isolated COA, 375 (60%) were men, and 246 (40%) were women. Women had similar ASCVD risk profile and daytime BP as men. However, women had less nocturnal dipping (7 ± 5 mm Hg vs 16 ± 7 mm Hg, P < 0.001), higher pulmonary artery mean pressure (23 mm Hg [range: 16-31] vs 20 mm Hg [range: 15-28], P = 0.04), and higher pulmonary vascular resistance index (3.41 ± 1.14 WU · m2 vs 3.02 ± 0.76 WU · m2, P = 0.006). Female sex was associated with all-cause mortality (adjusted hazard ratio 1.26, 95% confidence interval 1.04-1.94) and cardiovascular mortality (adjusted hazard ratio 1.38, 95% confidence interval 1.09-2.18). ConclusionsWomen had a higher risk of both cardiovascular mortality and all-cause mortality compared to the risks in men. This difference may be related to the higher-than-expected ASCVD risk factors, abnormal nocturnal blood pressure, and pulmonary hypertension observed in women in this cohort. Further studies are required to identify optimal measures to address these risk factors.

Resting heart rate but not heart rate variability is associated with the normal-weight obesity phenotype.

To determine differences in resting heart rate variability (HRV) and heart rate (HR) between young adults with normal-weight obesity (NWO) and normal-weight lean (NWL). A total of 65 normal-weight individuals (18-25 years old, 50 women, body mass index 18.5 to 24.9 kg/m2) were included in this cross-sectional study. Body fat percentage was determined using a whole-body dual energy x-ray absorptiometry scanner. Resting HRV and HR were assessed with the Polar RS800CX. Forty-one participants were classified as NWO and 24 NWL using cutoff points for body fat percentage (33.3% for women and 23.1% for men). There were no differences in HRV between NWO and NWL groups (all p > .05). HR was higher in NWO (mean 70 beats per minute [bpm], standard deviation [SD] 8) than in NWL adults (mean 65 bpm, SD 10), the adjusted mean difference 5 bpm (95% CI, 0 to 10 bpm). HR is a noninvasive biomarker and relatively cheap, fast, and easy to measure that could detect "apparently healthy" young individuals with an adverse cardiovascular disease risk profile despite presenting a normal body weight.

Men with nonobstructive coronary disease have higher burden of ischemic heart disease detected by cardiopulmonary exercise test.

Nonobstructive coronary artery disease (NOCAD), characterized by the presence of myocardial ischemic symptoms and signs without obstructive coronaries, is a common clinical condition, but it is less well understood. Few studies have analyzed the gender differences in inducible myocardial ischemia assessed by cardiopulmonary exercise test (CPET) in NOCAD. We conducted a study of 289 NOCAD patients (mean age 60, 56% women) with ischemic symptoms and confirmed ⫹50% coronaries stenoses by coronary angiography who underwent symptom-limited CPET. We assessed ischemic response using predicted % peak VO2 , O2 pulse trajectory, and exercise ECG test. Men with NOCAD had significantly lower predicted % peak VO2 (62% vs. 73%), higher proportions of flattening pattern (16% vs. 2%), and downward patterns of O2 pulse trajectory (2% vs. 0%) (p < .0001) compared with women. In contrast, women with NOCAD had a higher prevalence of shallow patterns of O2 pulse trajectory (21% vs. 6%, p < .0001). Men with NOCAD had a higher risk ischemic profile (medium risk: 63% vs. 54%, high risk: 18% vs. 4%, p < .0001). After adjustment, men with NOCAD had significantly lower predicted % peak VO2 (β -27.4, 95% CI -30.74 to -24.07), higher risk for abnormal O2 pulse trajectories (OR 4.21, 95% CI 1.93 to 9.19), and myocardial ischemia risk per CPET parameters (OR 3.14, 95% CI 1.78 to 5.54) (p < .0001). Men with NOCAD had a higher risk profile for ischemic heart disease per CPET. Therefore, they should receive rigorous management and follow-up to prevent cardiovascular events.

Cardiovascular risk, social vigilance, and stress profiles of male law enforcement officers versus civilians.

This study examined the cardiovascular disease (CVD) risk profiles of male law enforcement officers (LEOs) and civilians. CVD risk profiles were based on data collected using traditional objective (e.g., resting BP, cholesterol), novel objective (e.g., ambulatory BP) and self-report measures (e.g., EMA social vigilance). A subset of male LEOs (n = 30, M age = 41.47, SD = 8.03) and male civilians (n = 120, M age = 40.73, SD = 13.52) from a larger study were included in analyses. Results indicated LEOs had significantly higher body mass index [BMI], 31.17kg/m2 versus 28.87kg/m2, and exhibited significantly higher trait and state social vigilance across multiple measures, whereas perceived stress was higher among civilians. Findings highlight the need for future research examining CVD risk associated with occupational health disparities, including attributes of individuals entering certain professions as well as experiential and environmental demands of the work.

Hypertensive disorders of pregnancy and cardiovascular disease risk: a Mendelian randomisation study

ObjectiveObservational studies show that hypertensive disorders of pregnancy (HDPs) are related to unfavourable maternal cardiovascular disease (CVD) risk profiles later in life. We investigated whether genetic liability to pre-eclampsia/eclampsia and...
