Remnant cholesterol, LDL cholesterol, and apoB absolute mass changes explain results of the PROMINENT trial

Background and aimsThe PROMINENT trial, a cardiovascular outcome trial of the triglyceride- and remnant cholesterol-lowering agent pemafibrate, has shown neutral results despite reduction in plasma triglycerides and remnant cholesterol. We tested the hypothesis that absolute mass changes in remnant cholesterol, LDL cholesterol, and apolipoprotein B explain the results of the PROMINENT trial. MethodsAmong 108,431 individuals from the Copenhagen General Population Study (CGPS), those who met the key inclusion criteria of the PROMINENT trial were analyzed to mimic the trial design. Endpoint atherosclerotic cardiovascular disease (ASCVD) was cardiovascular death, myocardial infarction, ischemic stroke, and coronary revascularization as defined in PROMINENT. ResultsIn the PROMINENT trial, treatment with pemafibrate resulted in -7 mg/dL (−0.18 mmol/L; -18 %) change in remnant cholesterol, +10 mg/dL (+0.26 mmol/L; +12 %) LDL cholesterol, and +5 mg/dL (+0.05 g/L; +5 %) apolipoprotein B. In the CGPS mimicking PROMINENT, the estimated hazard ratios for ASCVD were 0.97 (95 % confidence interval: 0.94–0.99) for a -7 mg/dL (−0.18 mmol/L) change in remnant cholesterol, 1.04 (1.01–1.07) for a +10 mg/dL (+0.26 mmol/L) change in LDL cholesterol, and 1.02 (1.01–1.03) for a +5 mg/dL (+0.05 g/L) change in apolipoprotein B. When combining absolute changes in remnant cholesterol, LDL cholesterol, and apolipoprotein B, the estimated hazard ratio for ASCVD was 1.05 (0.96–1.14) in the CGPS mimicking PROMINENT compared to 1.03 (0.91–1.15) in the PROMINENT trial. ConclusionsAbsolute mass changes in remnant cholesterol, LDL cholesterol, and apolipoprotein B can explain results of the PROMINENT trial. The 3 mg/dL (0.08 mmol/L) higher total atherogenic cholesterol together with 5 mg/dL (0.05 g/L) higher apolipoprotein B seem to explain the trend toward more ASCVD in the pemafibrate arm.

Association of Ultraprocessed Food Consumption with Risk of Cardiovascular Disease Among Individuals with Type 2 Diabetes: Findings from the UK Biobank.

Among patients with diabetes, who have modified nutritional behavior and a higher risk of cardiovascular disease (CVD), the influence of ultraprocessed foods (UPFs) on CVD remains unknown. The study aims to evaluate the association between UPF intake and the risk of CVD among individuals with type 2 diabetes (T2D) and further examine the potential biological pathways linking the association. This study includes 5405 participants with T2D who provided at least one 24-h dietary recall from the UK Biobank study. In the fully adjusted models, a 10% increase in the proportion of UPFs is associated with higher hazards of overall CVD (hazard ratio [HR]: 1.10; 95% confidence interval [CI]: 1.04, 1.15), coronary heart disease (HR: 1.10; 95% CI: 1.04, 1.16), heart failure (HR: 1.14; 95% CI: 1.05, 1.25), but not stroke (HR: 1.01; 95% CI: 0.90, 1.12). Cystatin C, high-density lipoprotein cholesterol (HDL-C), apolipoprotein A, C-reactive protein, and body mass index collectively explain 26.9% (12.8%, 48.5%) of the association between UPF intake and the risk of overall CVD. Higher UPF intakes are associated with increased hazards of CVD among individuals with T2D, and the association is partly mediated through worsening biomarkers of renal function, lipid metabolism, inflammation, and body weight.

Differential age-specific associations of LDL cholesterol and body mass index with coronary heart disease

Background and aimsLow‐density lipoprotein cholesterol (LDLc) and body mass index (BMI) are not always correlated and their relationship is probably dependent on age, indicating differential age-specific associations of these factors with health outcomes. We aim to discriminate the roles of LDLc and BMI in coronary heart disease (CHD) across different age groups. MethodsThis is a prospective cohort study of 368,274 participants aged 38–73 years and free of CHD at baseline. LDLc and BMI were measured at baseline, and incident CHD was the main outcome. Cox proportional hazards model and restricted cubic spline (RCS) regression were used to estimate hazard ratio (HR) and 95% confidence interval (CI) of exposure on CHD. ResultsAfter a mean of 12 years of follow-up, similar relationships of LDLc and BMI with CHD risk were observed in the overall population but in differential age-specific patterns. Across the age groups of <50, 50–54, 55–59, 60–64 and ≥ 65 years, the LDLc-CHD association diminished with the adjusted HRs decreasing from 1.35, 1.26, 1.19, 1.11 to 1.08; while no declining trend was found in BMI-CHD relationship with the adjusted HRs of 1.15, 1.11, 1.12, 1.13 and 1.15, respectively. The interaction and mediation between LDLc and BMI on CHD risk were more pronounced at young-age groups. LDLc-CHD but not BMI-CHD association was dependent on sex, metabolic syndrome and lipid-lowering drugs use. ConclusionsThere were differential age-specific associations of LDLc and BMI with the risk of developing CHD, calling for future efforts to discriminate the age-different benefits from lipids management or weight control on the primary prevention for CHD.

Lutein in chronic diseases: A mini review

Lutein is a xanthophyll carotenoid that can be found in a divergency of fruits and plants. Its main action is to protect eye health and vision. Its antioxidant properties play a crucial role in eye agitations, in decreasing inflammation, in protecting the neural tissues from chemical analyzed hypoxia and cell apoptosis. Lutein supplementation in associa- tion with low-calorie diet had a notable abatement in fat-free mass, visceral fat and serum levels of total cholesterol and LDL (low-density lipoprotein)-cholesterol. Lutein may also have a natural anti-cancer effect. This is because foods rich in lutein have antioxidant activity and oppose inflammation and oxidative stress. The aim of this mini-review was to provide an up-to-date overview of the main effects of lutein in health and disease.

Psychological profile of Chinese peritoneal dialysis patients during the Omicron pandemic in 2022

ObjectiveThe aim of this study was to determine the psychological status of peritoneal dialysis (PD) patients who were blocked during the 2022 Omic Pandemic in Shanghai.MethodsThis was an observational and cross-sectional study. We selected 172 PD patients from the peritoneal dialysis center of Ruijin Hospital, Shanghai Jiao Tong University School of Medicine, during the quarantine of the Omicron pandemic in Shanghai from April to May 2022. General data and biochemical indices were collected. The Kidney Disease Quality of Life (SF-36) questionnaire was used to evaluate the psychological state of the patients during the quarantine.ResultsAccording to the assessment of the SF-36 scale, the physiological and psychological health status of PD patients was better than that before quarantine (P < 0.05). According to the comparison of biochemical indices, the high-density lipoprotein, total cholesterol and body mass index (BMI) levels were lower in patients after quarantine than before quarantine, while the blood phosphorus, blood calcium and haemoglobin levels were greater after quarantine (P < 0.05). Logistic regression analysis revealed that health changes were positively correlated with age of penetration (years) (OR = 1.031, 95% CI = 1.005–1.058); however, physiological function was negatively correlated with sex (OR = 0.198, 95% CI = 0.044–0.899). Energy was significantly positively correlated with closed-loop time (OR = 1.063, 95% CI = 1.001–1.128) (P < 0.05). There were no significant differences in biochemical indices or quality of life between APD patients and non-APD patients (P > 0.05). According to the results of the abstract independent sample T test, when comparing the various dimensions of the SF-36 scale, for the dimensions of physiological function, pain and energy, the PD patients were better than the HD patients were (P < 0.05). Similarly, for the dimension of physiological function, the HD patients were better than the PD patients were (P < 0.05). During the quarantine period from April to May in Shanghai, the infection rate of PD patients was lower than usual (P < 0.05).ConclusionsDuring the Omicron pandemic in Shanghai in 2022, PD patients exhibited relatively stable psychological and physiological states and a low infection rate. Compared with HD patients, PD patients had better adaptability. Especially in the context of the COVID-19 pandemic, peritoneal dialysis has more advantages.

Associations of cholecystectomy with metabolic health changes and incident cardiovascular disease: a retrospective cohort study

Although some studies conducted about the risk of cholecystectomy and cardiovascular disease, there was a limit to explaining the relationship. We investigated the short-term and long-term relationship between cholecystectomy and cardiovascular disease, and evidence using the elements of the metabolic index as an intermediate step. It was a retrospective cohort study and we used the National Health Insurance Service database of South Korea between 2002 and 2015. Finally, 5,210 patients who underwent cholecystectomy and 49,457 at 1:10 age and gender-matched controls of subjects were collected. The main results was estimated by Multivariate Cox proportional hazard regression to calculate the hazard ratio (HR) with 95% confidence interval (CI) for risk of cardiovascular disease after cholecystectomy. Regarding short-term effects of cholecystectomy, increased risk of cardiovascular disease (aHR 1.35, 95% CI 1.15–1.58) and coronary heart disease (aHR 1.77, 95% CI 1.44–2.16) were similarly seen within 2 years of surgery. When analyzing the change in metabolic risk factors, cholecystectomy was associated with a change in systolic blood pressure (adjusted mean [aMean]: 1.51, 95% CI: [− 1.50 to − 4.51]), total cholesterol (aMean − 14.14, [− 20.33 to 7.95]) and body mass index (aMean − 0.13, [− 0.37 to 0.11]). Cholecystectomy patients had elevated risk of cardiovascular disease in the short-term, possibly due to the characteristics of the patient before surgery. The association of cholecystectomy and cardiovascular disease has decreased after 2 years in patients who underwent cholecystectomy, suggesting that because of improvement of metabolic health, cholecystectomy-associated elevation of cardiovascular disease risk may be ameliorated 2 years after cholecystectomy.

МЕТЕОЗАВИСИМОСТЬ: МИФ ИЛИ РЕАЛЬНОСТЬ (НА ПРИМЕРЕ АРТЕРИАЛЬНОЙ ГИПЕРТОНИИ)

The paper examines the relationship of meteorological factors with the development of cardiovascular complications. Statistically significant seasonal fluctuations in the level and variability of blood pressure, heart rate, cholesterol, glucose, and body mass have been revealed. The variability of blood pressure is maximal in winter and minimal in summer. It is known that heat and cold waves are associated with an increase in mortality and cardiovascular complications, including hypertensive crises. Their frequency depends on the level of cardiovascular risk of a patient and is maximal in people with coronary heart disease, cerebrovascular disease, and type 2 diabetes. The influence of such poorly predictable factors as temperature waves and magnetic storms has been less studied. It seems promising to examine the relationship of the variability of blood pressure and complications of arterial hypertension with meteorological factors using the method for remote blood pressure monitoring, which is currently actively implemented in the regions of the Russian Federation.

Exploring the impact of health education on medication adherence and health outcomes in low-income neighborhoods: An observational study

Background: Medication adherence and health outcomes are influenced by multiple factors, including patient education. Aims and Objectives: The aims and objectives of the study are to explore the impact of health education on medication adherence and various health outcomes in low-income neighborhoods. Materials and Methods: An observational study was conducted involving 100 participants from low-income neighborhoods, aged 18–65, who were prescribed at least one chronic medication. Participants underwent a comprehensive health education program focusing on medication adherence, potential side effects, dietary habits, and physical activity. Outcomes were measured using the Morisky Medication Adherence Scale (MMAS-8), biometric values (e.g., blood pressure, blood sugar levels, cholesterol, and body mass index [BMI]), self-reported health status, hospitalization records, medication side-effects awareness, and dietary habits. Results: Post-education, there was a significant improvement in MMAS-8 scores (5.3 pre to 6.8 post, P&lt;0.001). Biometric outcomes revealed a decrease in average blood pressure (from 145/90 mmHg to 130/85 mmHg), fasting blood sugar (from 150 mg/dL to 130 mg/dL), cholesterol levels (from 210 mg/dL to 180 mg/dL), and BMI (from 28.5 to 27.3), all with a statistical significance of P&lt;0.01. Participants reporting “Good” or “Very Good” health increased from 45% to 65%, and those reporting regular physical activity increased from 25% to 45% (P&lt;0.05). Hospitalizations/medical visits decreased from an average of 2.1–1.3 over 6 months (P&lt;0.01). The proportion of participants with awareness of their medication's side effects significantly increased from 30% before the health education program to 70% afterwards (P&lt;0.001). In addition, participants reporting adherence to dietary guidelines rose from 20% to 50% (P&lt;0.01). Conclusion: Health education appears to have a substantial positive impact on medication adherence, biometric health outcomes, and overall well-being in low-income neighborhoods. Structured health education interventions may play a pivotal role in improving community health.

Effects of a multicomponent training followed by a detraining period on metabolic syndrome profile of older adults

AimsThe present study sought to analyze the effects of 6-month multicomponent training (MCT) combined with a 4-month detraining on metabolic syndrome (MetS) profile among older adults with decreased functional capacity. MethodsThis quasi-experimental study included a total of 104 older adults (80.5 ± 6.0 years) and the sample was divided into a training (TRAIN, n = 55) or control group (CON). Harmonized definition was used to diagnose the MetS. Functional capacity, blood biochemical parameters, blood pressure, body composition and anthropometric measurements were assessed 3 times. Analysis of variance for repeated measures and Wilcoxon signed-rank test were used to check the differences within groups. ResultsTRAIN decreased diastolic blood pressure (DBP), high-density lipoprotein cholesterol (HDLC) and total fat mass during training period, whereas CON did not show any significant changes. During detraining, TRAIN increased HDLC, systolic blood pressure (SBP), waist circumference (WC) and total fat mass; and decreased glucose and fat free mass, whereas CON increased the concentration of glucose and HDLC. From baseline to post-detraining assessment, CON increased the concentration of triglycerides and the WC, while TRAIN only increased the WC (all p < 0.05). ConclusionsExercise can be a key component in the treatment of the MetS, since MCT seems to be effective to decrease DBP and total fat mass. Nevertheless, 4-months of detraining could cause a drop of total fat mass, but no in DBP. To avoid reversibility of the benefits obtained, it could be beneficial to promote continuing exercise programs. Trial registrationClinicalTrial.gov identifier: NCT03831841

The magnitude and direction of the relationship between risk factor and cognition depends on age: a pooled analysis of 5 community-based studies

The mixed evidence of the association between high levels of cardiovascular risk factors (CVRF) and the risk for cognitive impairment may be due to confounding of age across studies. We pooled and harmonized individual-level data (30,967 persons, age range 42–96 years) from five prospective cohorts to investigate by 1 year age increments to investigate whether or not there is change in slope describing the association of CVRF to a cognitive outcome (Digit Symbol Substitution Test; DSST). The CVRF included: systolic and diastolic blood pressure, total cholesterol, fasting glucose and body mass index. Linear and quadratic piecewise regression models were fit to the trajectory patterns of these slopes (betas). The pattern of yearly slope changes showed higher CVRF were associated with lower DSST, but associations attenuated toward zero as age increased for all but DBP where 1 year slopes for DBP changed direction from negative to positive from mid- to late-age. Age is not only a driver of cognitive decline—age also modifies the direction and strength of the association of cognitive function to CVRF and cohort age may be one reason why the evidence for CVRF-CD association is mixed.

External validation of a novel nomogram for diagnosis of Protein Energy Wasting in adult hemodialysis patients.

Protein Energy Wasting (PEW) has high incidence in adult hemodialysis patients and refers to a state of decreased protein and energy substance. It has been demonstrated that PEW highly affects the quality of survival and increases the risk of death. Nevertheless, its diagnostic criteria are complex in clinic. To simplify the diagnosis method of PEW in adult hemodialysis patients, we previously established a novel clinical prediction model that was well-validated internally using bootstrapping. In this multicenter cross-sectional study, we aimed to externally validate this nomogram in a new cohort of adult hemodialysis patients. The novel prediction model was built by combining four independent variables with part of the International Society of Renal Nutrition and Metabolism (ISRNM) diagnostic criteria including albumin, total cholesterol, and body mass index (BMI). We evaluated the performance of the new model using discrimination (Concordance Index), calibration plots, and Clinical Impact Curve to assess its predictive utility. From September 1st, 2022 to August 31st, 2023, 1,158 patients were screened in five medical centers in Shanghai. 622 (53.7%) hemodialysis patients were included for analysis. The PEW predictive model was acceptable discrimination with the area under the curve of 0.777 (95% CI 0.741-0.814). Additionally, the model revealed well-fitted calibration curves. The McNemar test showed the novel model had similar diagnostic efficacy with the gold standard diagnostic method (p > 0.05). Our results from this cross-sectional external validation study further demonstrate that the novel model is a valid tool to identify PEW in adult hemodialysis patients effectively.

Thermal evaporation as sample preparation for silver-assisted laser desorption/ionization mass spectrometry imaging of cholesterol in amyloid tissues.

Cholesterol plays an important biological role in the body, and its disruption in homeostasis and synthesis has been implicated in several diseases. Mapping the locations of cholesterol is crucial for gaining a better understanding of these conditions. Silver deposition has proven to be an effective method for analyzing cholesterol using mass spectrometry imaging (MSI). We optimized and evaluated thermal evaporation as an alternative deposition technique to sputtering for silver deposition in MSI of cholesterol. A silver layer with a thickness of 6 nm provided an optimal combination of cholesterol signal intensity and mass resolution. The deposition of an ultrathin nanofilm of silver enabled high-resolution MSI with a pixel size of 10 μm. We used this optimized method to visualize the distribution of cholesterol in the senile plaques in the brains of APP/PS1 mice, a model that resembles Alzheimer's disease pathology. We found that cholesterol was evenly distributed across the frontal cortex tissue, with no evidence of plaque-like accumulation. Additionally, we investigated the presence and distribution of cholesterol in myocardial sections of a human heart affected by wild-type ATTR amyloidosis. We identified the presence of cholesterol in areas with amyloid deposition, but complete colocalization was not observed.

Association of cardiometabolic factors and insulin resistance surrogates with mortality in participants from the Korean Genome and Epidemiology Study

BackgroundSimple biochemical and anthropometric measurements such as fasting blood glucose (FBG), triglycerides (TG), high-density lipoprotein cholesterol (HDL-C), waist circumference (WC), and body mass index (BMI) are used to formulate insulin resistance (IR) indices. Whether these indices provide new predictive information for mortality remains unknown. This study examined the relationships of biochemical, anthropometric, and IR indices with mortality risk, as well as their predictive performance.MethodsThe data source was the Korean Genome and Epidemiology Study (2004–2020) involving 114,957 participants whose data were linked to death records. The IR indices- triglyceride-glucose index (TyG), TyG-BMI, TyG-WC, visceral adiposity index (VAI), lipid accumulation product (LAP), and metabolic score for insulin resistance (METS-IR) were computed using standard formulae. The associations were examined using restricted cubic splines. The predictive performance was compared using the log-likelihood ratio chi-square test.ResultsBody mass index was U-shaped, HDL-C was reverse J-shaped, and FBG and TG levels were J-shaped associated with all-cause mortality. Results showed U-shaped (TyG), J-shaped (TyG-BMI, VAI, LAP, and METS-IR), and reverse J-shaped (TyG-WC) associations with all-cause mortality. The percentages of new predictive information for all-cause mortality explained by the FBG level, BMI, TyG-BMI, and METIR were 3.34%, 2.33%, 1.47%, and 1.37%, respectively. Other IR indices and biochemical and anthropometric measurements provided < 1.0% of new predictive information. For cardiovascular disease mortality, the FBG, BMI, METIR, TyG-BMI, and HDL-C levels explained 2.57%, 2.12%, 1.59%, 1.30%, and 1.27% of new predictive information respectively. Moreover, the risks of cancer mortality explained by FBG level, VAI, and HDL-C level were 2.05%, 1.49%, and 1.28%, respectively.ConclusionsFasting blood glucose level is a superior predictor of mortality risk and may be used as a simple predictive and preventative factor.

Role of Sex in the Association of Socioeconomic Status With Cardiovascular Health in Black Americans: The Jackson Heart Study.

Socioeconomic status (SES) is associated with cardiovascular health (CVH). Potential differences by sex in this association remain incompletely understood in Black Americans, where SES disparities are posited to be partially responsible for cardiovascular inequities. The association of SES measures (income, education, occupation, and insurance) with CVH scores was examined in the Jackson Heart Study. American Heart Association CVH components (non-high-density-lipoprotein cholesterol, blood pressure, diet, tobacco use, physical activity, sleep, glycemia, and body mass index) were scored cross-sectionally at baseline (scale: 0-100). Differences in CVH and 95% CIs (Estimate, 95% CI) were calculated using linear regression, adjusting for age, sex, and discrimination. Heterogeneity by sex was assessed. Participants had a mean age of 54.8 years (SD 12.6 years), and 65% were women. Lower income, education, occupation (non-management/professional versus management/professional occupations), and insurance status (uninsured, Medicaid, Veterans Affairs, or Medicare versus private insurance) were associated with lower CVH scores (all P<0.01). There was heterogeneity by sex, with greater magnitude of associations of SES measures with CVH in women versus men. The lowest education level (<high school) versus highest (>high school) was associated with 8.8-point lower (95% CI: -10.2 to -7.3) and 5.4-point lower (95% CI: -7.2 to -3.6) CVH scores in women and men, respectively (interaction P=0.003). The lowest (<25 000) versus highest level of income (≥$75 000) was associated with a greater reduction in CVH scores in women than men (interaction P=0.1142). Among Black Americans, measures of SES were associated with CVH, with a greater magnitude in women compared with men for education and income. Interventions aimed to address CVH through SES should consider the role of sex.

Dynapenic Abdominal Obesity as a Risk Factor for Metabolic Syndrome in Individual 50 Years of Age or Older: English Longitudinal Study of Ageing

ObjectivesTo analyse whether dynapenic abdominal obesity is a risk factor for Metabolic syndrome (MetS) and its components in individuals 50 years of age or older. DesignA longitudinal study was conducted with an eight-year follow-up. SettingRepresentative sample of community-dwelling participants of the English Longitudinal Study of Ageing (ELSA). Participants3,952 individuals free of MetS at baseline. MeasurementsDynapenic abdominal obesity was defined based on waist circumference (> 102 cm for men and > 88 cm for women) and grip strength (< 26 kg for men and < 16 kg for women). The participants were classified as non-abdominally obese/non-dynapenic (NAO/ND - reference group), abdominally obese/non-dynapenic (AO/ ND), non-abdominally obese/dynapenic (NAO/D) and abdominally obese/dynapenic (AO/D). The outcome was the incidence of MetS based on the presence of three or more of the following criteria: hypertriglyceridemia, hyperglycaemia, low HDL cholesterol, arterial hypertension or body mass index ≥ 30 kg/m2 throughout eight-year follow-up. Additionally, the incidence of each component of MetS was also analyzed. Poisson regression models were run and controlled for sociodemographic, behavioural and clinical variables. ResultsThe mean age of the participants was 65 years and 55% were women. The prevalence of AO/ND, NAO/D and AO/D were 35.3, 4.3 and 2.2%, respectively. At the end of follow-up 558 incident cases of MetS were recorded. The adjusted model demonstrated that although abdominal obesity was a risk factor for MetS (IRR: 2.26; 95% CI: 1.87–2.73), the IRR was greater in AO/D individuals (IRR: 3.34; 95% CI: 2.03–5.50) compared with ND/NAO group. Furthermore, ND/AO was a risk factor for incidence of hypertriglyceridemia (IRR: 1.27; 95% CI: 1.06–1.52), hyperglycaemia (IRR: 1.41; 95% CI: 1.18–1.69), low HDL cholesterol (IRR: 1.70; 95% CI: 1.32–2.19) and BMI ≥ 30 kg/ m2 (IRR: 2.58; 95% CI: 2.04–3.26) while D/AO was a risk factor for hyperglycaemia (IRR: 1.78; 95% CI: 1.02–3.10), low HDL cholesterol (IRR: 2.36; 95% CI: 1.10–5.08), and BMI ≥ 30 kg/m2 (IRR: 2.79; 95% CI: 1.38–5.62). ConclusionsDynapenic abdominal obesity increases the risk of MetS, with a higher IRR compared to obesity alone. The understanding of this synergic action could guide specific clinical strategies, enabling the prevention of metabolic changes that can lead to cardiovascular disease, disability and death.

The modifying effects of cardiovascular risk factors on the relationship between lifetime discrimination and cognitive function: Study of Healthy Aging in African Americans (STAR)

AbstractBackgroundDiscrimination is a root cause of health inequities contributing to the excess burden of cognitive impairment among Black Americans. Using the Study of Healthy Aging in African Americans (STAR) we examined whether the effect of lifetime discrimination on late‐life cognitive decline was magnified by early adulthood cardiovascular risk factors.MethodSTAR enrolled long‐term Kaiser Permanente Northern California members ages 50+ who identify as Black/African American. In early adulthood, participants completed Multiphasic Health Check‐ups (MHC; 1964‐1985) where systolic blood pressure (BP), total cholesterol, and body mass index (BMI) were assessed. A latent class analysis identified groups based on responses to the Major Experiences of Discrimination Scale and gender. Standardized z‐scores for executive function (EF) and verbal episodic memory (VEM) were measured over 3 waves (2018‐2022) using the Spanish and English Neuropsychological Assessment Scales. Linear mixed models with random intercepts and slopes associated latent class with cognitive decline adjusting for age at MHC, age at baseline cognitive assessment, education, and assessment mode (in‐person/telephone). Separate models tested class*cardiovascular risk factor interactions.ResultParticipants (n = 646) averaged 27.7(SD = 7.3) years of age at MHC and 68.5(SD = 8.8) at baseline cognitive assessment (Table 1). Four latent classes were identified: men reporting widespread discrimination (Class‐1men; 12%), women reporting widespread discrimination (Class‐2women; 22%), men and women reporting unfair police treatment (Class‐3police; 17%), and men and women reporting little/no discrimination (Class‐4no_discimination; 49%). Using Class‐4no_discimination as reference, those in Class‐2women had significantly higher baseline EF (β(95% CI):0.18(0.03,0.34)) while Class‐1men (β:0.04(‐0.15,0.23)) and Class‐3police (β:‐0.08(‐0.25,0.09)) did not differ (Figure 1). Class‐2women (β:0.17(0.00,0.33)) had higher baseline VEM compared to Class‐4no_discrimination while Class‐1men (β:‐0.40(‐0.60,‐0.19)) and Class‐3police (β:‐0.27(‐0.46,‐0.09)) had significantly lower (Figure 1). There were no differences in rate of decline. There was a systolic BP*class interaction (p = 0.04) where 5 mm Hg higher systolic BP in early adulthood was associated with worse EF for Class‐3police (β:‐0.07(‐0.12,‐0.02)) compared to Class‐4no_discrimination while Class‐1men and Class‐2women did not differ (Figure 2). This pattern was similar for VEM but non‐significant (interaction p = 0.07). We found no interactions with total cholesterol or BMI.ConclusionFor Black Americans, discriminatory experiences may differentially impact late‐life cognition, and elevated systolic BP in early adulthood may exacerbate this harm.

Preparation of a novel brain-targeted EGCG liposome and its antioxidative neuroprotection

(-)-Epigallocatechin-3-gallate (EGCG) possesses potent antioxidant and neuroprotective properties. In this study, a novel glucose-modified EGCG encapsulated liposome (EGCG-Glu-Lip) was developed and characterized. EGCG-Glu-Lip liposome’s cytotoxicity, brain targeting ability, and its antioxidative neuroprotection were examined via bEnd.3 and PC12 cells testing. EGCG-Glu-Lip liposome particle mean size was 158.7 nm, with encapsulation efficiency 73.05 % under EGCG/lipid mass ratio 1:22 and soybean phospholipids (SPC) to cholesterol (Chol) mass ratio 3.84:1. EGCG-Glu-Lip exhibited less cytotoxicity, stronger protection to PC12 cells from H2O2 induced oxidative damage, keeping reactive oxygen species (ROS) level. Glucose modified liposome (Glu-Lip) cellular uptake in bEnd.3 and PC12 cells were 1.5-fold and 1.3-fold higher than that of Lip, supporting EGCG-Glu-Lip possessing enhanced blood–brain barrier (BBB) permeability mediated via glucose transporter protein 1 (GLUT1) and neuronal cell uptake for brain targeting. EGCG-Glu-Lip could provide an efficient nano delivery pathway to deliver sufficient EGCG to brain tissue exerting its antioxidative neuroprotection more efficiently.

Long-Term Mortality in Patients With Severe Hypercholesterolemia Phenotype From a Racial and Ethnically Diverse US Cohort.

Tools for mortality prediction in patients with the severe hypercholesterolemia phenotype (low-density lipoprotein cholesterol ≥190 mg/dL) are limited and restricted to specific racial and ethnic cohorts. We sought to evaluate the predictors of long-term mortality in a large racially and ethnically diverse US patient cohort with low-density lipoprotein cholesterol ≥190 mg/dL. We conducted a retrospective analysis of all patients with a low-density lipoprotein cholesterol ≥190 mg/dL seeking care at Montefiore from 2010 through 2020. Patients <18 years of age or with previous malignancy were excluded. The primary end point was all-cause mortality. Analyses were stratified by age, sex, and race and ethnicity. Patients were stratified by primary and secondary prevention. Cox regression analyses were used to adjust for demographic, clinical, and treatment variables. A total of 18 740 patients were included (37% non-Hispanic Black, 30% Hispanic, 12% non-Hispanic White, and 2% non-Hispanic Asian patients). The mean age was 53.9 years, and median follow-up was 5.2 years. Both high-density lipoprotein cholesterol and body mass index extremes were associated with higher mortality in univariate analyses. In adjusted models, higher low-density lipoprotein cholesterol and triglyceride levels were associated with an increased 9-year mortality risk (adjusted hazard ratio [HR], 1.08 [95% CI, 1.05-1.11] and 1.04 [95% CI, 1.02-1.06] per 20-mg/dL increase, respectively). Clinical factors associated with higher mortality included male sex (adjusted HR, 1.31 [95% CI, 1.08-1.58]), older age (adjusted HR, 1.19 per 5-year increase [95% CI, 1.15-1.23]), hypertension (adjusted HR, 2.01 [95% CI, 1.57-2.57]), chronic kidney disease (adjusted HR, 1.68 [95% CI, 1.36-2.09]), diabetes (adjusted HR, 1.79 [95% CI, 1.50-2.15]), heart failure (adjusted HR, 1.51 [95% CI, 1.16-1.95]), myocardial infarction (adjusted HR, 1.41 [95% CI, 1.05-1.90]), and body mass index <20 kg/m2 (adjusted HR, 3.36 [95% CI, 2.29-4.93]). A significant survival benefit was conferred by lipid-lowering therapy (adjusted HR, 0.57 [95% CI, 0.42-0.77]). In the primary prevention group, high-density lipoprotein cholesterol <40 mg/dL was independently associated with higher mortality (adjusted HR, 1.49 [95% CI, 1.06-2.09]). Temporal trend analyses showed a reduction in statin use over time (P<0.001). In the most recent time period (2019-2020), 56% of patients on primary prevention and 85% of those on secondary prevention were on statin therapy. In a large, diverse cohort of US patients with the severe hypercholesterolemia phenotype, we identified several patient characteristics associated with increased 9-year all-cause mortality and observed a decrease in statin use over time, in particular for primary prevention. Our results support efforts geared toward early recognition and consistent treatment for patients with severe hypercholesterolemia.

Health outcomes of an ambulatory exercise-based cardiac rehabilitation program across patient risk categories

Abstract Background Exercise-based cardiac rehabilitation is recommended after an ST-segment elevation myocardial infarction (STEMI) to improve prognosis, quality of life and control of cardiovascular risk factors. Ambulatory training has been proposed as an alternative if in-hospital training is unavailable. Purpose To study the health outcomes of an ambulatory exercise-based Cardiac Rehabilitation Program (aCRP) in STEMI patients across different patient risk profiles. Methods A Phase 2 aCRP aimed to STEMI patients was implemented in our hospital in 2022. Conventional or cardiopulmonary exercise testing (C/CPET) was performed, patient risk was stratified as low risk or intermediate/high risk, and a 3-month, individualized aerobic and strength ambulatory training program was provided. C/CPET was repeated at the end of Phase 2 and peak oxygen consumption (peak VO2) was measured. Questionnaires were used to analyse quality of life (SF-36), depression (PHQ-2), anxiety (GAD-2), adherence to Mediterranean diet (PREDIMED) and weekly physical activity (IPAQ). Comparisons were performed between patients at low risk and patients at intermediate/high risk. A p&amp;lt;0.05 was considered statistically significant. Results The cohort comprised 41 patients who completed Phase 2 of aCRP (mean age 60.1±10.2 years, 82.9% male and 53.7% smokers) and were stratified as low risk (n=15, 36.6%) or intermediate/high risk (n=26, 63.4%). Reductions in systolic blood pressure (-7.9±15.7mmHg), LDL cholesterol (-59.5±35mg/dL), weight (-3±6.5kg) and body mass index (BMI, -1±2.2) were attained (all p&amp;lt;0.05). Smoking abstinence was accomplished in 90.9% of smokers and most patients achieved an LDL&amp;lt;55mg/dL target (75.6%). Quality of life improved (+8.4±23.7 points in SF-36, p=0.03) and anxiety symptoms diminished (-0.6±1.8 points in GAD2, p=0.04). A median 4.1±4.7ml/kg/min peak VO2 increase was achieved (+17.9% from baseline, p&amp;lt;0.001) and patients increased their reported weekly physical activity in 2681.1±3385.3 METS/week (+156.2% from baseline, p&amp;lt;0.001). No significant differences were noted between low risk and intermediate/high risk patients, except lower LDL&amp;lt;55mg/dL (65.4% vs. 93.3%, p=0.045) and higher weight loss and BMI reduction (-4.2±7.7 vs. -0.8±3kg, p=0.05 and -0.16±1.1 vs. -1.54±2.5, p=0.02, respectively) in intermediate/high risk patients. No readmissions for cardiovascular causes or complications of ambulatory training were registered. Conclusions In STEMI patients, a Phase 2 ambulatory Cardiac Rehabilitation Program can provide excellent control of cardiovascular risk factors, improve quality of life, and significantly increase functional capacity and reported weekly physical activity. Results are comparable in patients at low risk and intermediate/high risk of cardiac rehabilitation, which could support the inclusion of intermediate/high risk patients in ambulatory exercise-based cardiac rehabilitation programs if in-hospital supervised training is unavailable.Health outcomes of aCRP.

Abstract 14509: Life’s Simple 7 Predicts Mild Cognitive Impairment and Dementia in an Older Adult Population

Introduction: The American Heart Association’s Life’s Simple 7 (LS7) is a metric used widely in cardiovascular disease research. Lower scores on Life's Simple 7 predicts a lower performance on measures of cognitive functioning in young and middle-aged adults. Whether this is the case in older adults, however, is unclear. Hypothesis: Higher LS7 scores at baseline will be associated with a reduced risk of mild cognitive impairment (MCI) or dementia in older adults. Methods: Data from the Health and Retirement Study (HRS) between 2010 to 2018 was used in the analysis. The respondents were older than 50 years old and free from dementia and MCI at baseline. A survival-analysis was used and failures were defined as having MCI or dementia as determined by a 27-point Telephone Interview for Cognitive Status (TICS). LS7 scores were computed using smoking status (current and former), physical activity, diet, blood pressure, total cholesterol, blood glucose, and body mass index (BMI). A cox proportional hazard model was used to evaluate hazard ratio of developing mild cognitive impairment (MCI) and dementia in older adults. Results: There were 1,604 respondents with complete data included in this analysis. Of these respondents, 563 (35.1%) were male and 1,041 (64.9%) were female. 1,224 (76.3%) were white, 236 (14.7%) were black, and 143 (8.9%) were of another race. The average age of the respondents at baseline was 62.3±10.6 years. In 7,505 person-years, there were 1,197 events of MCI or dementia. After adjusting for age, gender, and educational attainment, a LS7 score less than 5 was associated with a 1.51 times higher risk of MCI or dementia than a LS7 score greater than 8 (p &lt; 0.005). However, LS7 scores between 7 or 8 was not significantly associated with increased risk of MCI or dementia compared to a LS7 score greater than 8 (HR: 1.12, p = 0.09). Conclusions: Lower LS7 score is associated with significantly lower performance on a measure of global cognitive functioning. As in young and middle-aged adults, maintaining a heart-healthy lifestyle may be important in preventing cognitive decline in older adults.
