Characterization of sedation strategies in real-world use of pulsed field ablation: sub-analysis of the EU-PORIA registry

Abstract Background/Introduction With the introduction of pulsed field ablation (PFA) to treat patients with atrial fibrillation (AF), there has been interest in studying workflow and sedation strategies to better understand how this new technology can be integrated into clinical practice. Purpose Characterize the use of general anesthesia (GA) versus deep sedation during real-world use of the pentaspline PFA catheter to treat AF. Methods EU-PORIA is an all-comer AF registry enrolling consecutive patients treated with the pentaspline PFA catheter at seven high-volume centers in Europe. Patients were treated based on institutional standard of care. During follow-up, any episode of atrial tachycardia (AT) or AF lasting longer than 30 seconds was considered an arrhythmia recurrence. Results EU-PORIA enrolled 1233 patients, of which 250 ablation cases were performed under GA and 983 cases were performed with deep sedation. Six out of the 7 participating centers employed a single sedation strategy (2 GA; 4 deep sedation), with one center doing a mix of both sedation and GA. The patient population treated with GA had fewer female patients (30% vs 40%; p=0.04), a lower prevalence of hypertension (43% vs 57%; p<0.01), and fewer paroxysmal AF patients (54% vs 62%; p<0.01). The ablation strategy was performed based on operator’s discretion. In the GA group, 72% of patients received a pulmonary vein isolation (PVI)-only ablation approach versus 90% of patients in the sedation group (p<0.01). The most common additional lesion set performed was posterior wall isolation which accounted for 23% and 7% of cases in the GA and sedation groups, respectively (p<0.01). Procedure times and fluoroscopy times were significantly shorter in the sedation group versus the GA group (51 [36-84] min vs 75[60-90] min; 13 [8-19] min vs 19 [15-26] min; p<0.01 for both). Mapping was used in 60% of cases in the GA group versus only 26% of cases in the sedation group. Overall, there were no differences in the incidence of serious adverse events, and no difference in chronic treatment success. At 1-year follow-up, 74.8% of patients (187/250) in the GA group and 73.8% of patients (725/983) in the sedation group were free from recurrent AF/AT. Conclusion(s) In this registry, the use of deep sedation for AF ablation with the pentaspline PFA catheter demonstrated a safety and efficacy profile consistent with those procedures performed under GA. The majority of the deep sedation procedures were PVI-only and performed in a less progressed AF disease state. It is worth noting that there may be certain patient populations and center restrictions where GA will remain the necessary approach for AF ablation. This characterization of real-world use warrants further evaluation to understand optimal sedation strategies that can be used with PFA technologies.

Serum lipid profiles and uptake of lipid-lowering therapy in patients with premature atherosclerotic cardiovascular disease (ASCVD) in comparison to older patients with ASCVD

Abstract Background Serum lipid levels are well-established risk factors for developing atherosclerotic cardiovascular disease (ASCVD). There are multiple guideline-supported treatments for managing dyslipidaemia for secondary prevention of ASCVD events. Lipid profiles and uptake of guideline-directed lipid-lowering therapy (GDLLT) is poorly characterised in patients with premature ASCVD compared to their older counterparts. Purpose To investigate serum lipid profiles and GDLLT uptake in patients with premature ASCVD in comparison to older patients with ASCVD. Methods Consecutive patients who underwent inpatient invasive coronary angiography at our institution between January 2019-December 2021 were examined. Patients with confirmed ASCVD on coronary angiography were stratified into two groups based on the 2019 ESC/EAS Guidelines for the Management of Dyslipidaemias definition of premature ASCVD: Group 1 comprised of younger patients (<55 years for men, <60 years for women) and Group 2 comprised of older patients (≥55 years for men, ≥60 years for women). Demographics, clinical and biochemical parameters (including lipid profiles) and medications were obtained from the electronic medical record and compared between groups to identify differences in risk factor profiles. Results A total of 1437 patients (980 [68.2%] male, mean age 62.4±13.9 years) underwent coronary angiography. 916 patients (63.7%) had confirmed ASCVD, of which 225 were classified as premature ASCVD (24.6%, mean age 47.8±10.1 years) vs 691 older patients with ASCVD (75.4%, mean age 69.5±8.7 years). Group 1 patients had significantly higher mean BMI (31.7±8.1 vs 69.5±8.7; p=0.001) and lower prevalence of hypertension (54.2% vs 69.5%; p<0.001) or chronic kidney disease (5.3% vs 12.6%; p=0.002) compared to Group 2. There were no significant differences in sex, diabetes mellitus, or smoking history. Lipid profiles were significantly different between the two groups: Group 1 had higher levels of total cholesterol (TC), LDL-C, triglycerides, and TC/HDL-C ratio, but lower HDL-C levels (all p<0.001). A lower proportion of Group 1 patients were on GDLLT (42.7% vs. 60.3%; p<0.001). Amongst patients on GDLLT, there were similar rates in the use of high-intensity statins between groups, but Group 1 patients were significantly more likely to have an LDL-C level ≥1.8mmol/L (p=0.003). Multivariable models for individual lipid subfractions, accounting for gender, cardiovascular risk factors, and LLT use, showed that all lipid parameters remained significantly different between groups (all p<0.001). Conclusion Patients with premature ASCVD have significantly different lipid profiles compared to older ASCVD patients. They also have lower uptake of guideline-directed LLT and are less likely to meet recommended LDL-C targets for high-risk ASCVD despite therapy. These findings highlight the need for tailored risk factor evaluation and management in this population.

Prevalence of Cardiometabolic Risk Factors in Women: Insights From the Houston HeartReach Study.

Cardiovascular disease is the leading cause of death among women in the United States. Past research has highlighted the importance of the relationship between female-specific demographics and traditional risk factors. The present analysis aimed to identify the prevalence of modifiable risk factors in women attending a community cardiovascular health screening. Data collected between 2011 and 2019 were obtained from the Houston HeartReach Registry. Participants were classified as having or not having each of 4 traditional cardiometabolic risk factors: hypertension, diabetes, body mass index indicating overweight or obesity, and dyslipidemia. Differences in prevalence were compared using the Pearson χ2 test. Most participants had hypertension, overweight or obesity, and dyslipidemia. Older women (≥65 years) had the highest prevalence of all cardiometabolic risk factors. Black participants had a higher prevalence of hypertension (P = .006) and a lower prevalence of dyslipidemia (P = .009) than non-Black participants. Hispanic participants had a lower prevalence of hypertension (P < .001) and a higher prevalence of overweight or obesity (P = .03) than non-Hispanic participants. Participants in the lowest household income bracket (<$25,000) were more likely to have diabetes (P = .001) and overweight or obesity (P = .004) than participants in the highest income bracket (≥$50,000). Unemployed participants had a higher prevalence of diabetes (P < .001), overweight or obesity (P = .004), and dyslipidemia (P < .001) than employed participants. Comorbidity analysis revealed clustering of multiple cardiometabolic risk factors. Moreover, risk factor hot spots were identified by zip code, which could help select future sites for targeted screening. The analysis found that cardiometabolic risk factor prevalence varies with demographic and socioeconomic status. Geographic areas where cardiometabolic risk factor prevalence was highest were also identified. Further participant recruitment and analysis are required to create predictive models of cardiovascular disease risk in women.

Cardiovascular disease in thymic cancer patients.

Cancer patients may have increased risk for adverse cardiac events, but our understanding of cardiovascular risk in thymic cancer patients is not clear. We sought to characterize baseline cardiometabolic risk factors before thymic cancer diagnosis and the potential association between cancer treatment and subsequent cardiac events. This was a retrospective cohort study evaluating patients with thymic cancer from 2003 to 2020 compared to age- and sex-matched controls without cancer. Baseline cardiovascular risk factors, cancer characteristics, and incidence of cardiac events were collected from the health information exchange. Multivariable regression was used to examine the impact of cardiovascular risk factors and cancer therapies. We compared 296 patients with pathology-confirmed thymic cancer to 2,960 noncancer controls. Prior to cancer diagnosis, thymic cancer patients (TCPs) had lower prevalence of hypertension, dyslipidemia, and diabetes mellitus and similar rates of obesity, tobacco use, and pre-existing cardiovascular disease (CVD) compared to controls. After diagnosis, high-risk TCPs (>2 cardiovascular risk factors or pre-existing CVD) had higher risk for cardiac events (HR 3.73, 95% CI 2.88-4.83, p < 0.001). In the first 3 years after diagnosis, TCPs had higher incidence of cardiac events (HR 1.38, 95% CI 1.01-1.87, p = 0.042). High-risk TCPs who received radiotherapy or chemotherapy had higher risk of cardiac events (HR 4.99, 95% CI 2.30-10.81, p < 0.001; HR 6.24, 95% CI 2.84-13.72, p < 0.001). Compared to noncancer controls, TCPs experienced more cardiac events when adjusted for risk factors. Patients with multiple cardiovascular risk factors receiving radiotherapy or chemotherapy had higher incidence of cardiac events.

P158 EDUCATION AS A PARAMETER FOR MANAGEMENT IN HYPERTENSION

Objective: Despite advancements, hypertension and its associated factors remain the leading cause of global death with concerning increases. This study aimed to estimate whether the impact of mass education in adults and subsequently in adolescents and children in Tunja, Boyacá, Colombia S.A influenced their knowledge of these factors. Methods: Cross-sectional and prospective community study in individuals &gt; 18 years, with open invitation to various points of care collecting information with Framingham surveys, blood pressure measurement, anthropometric variables, educational level, history, associated factors, and cardiovascular diseases knowledge of causes (CDKC). Conducting four sessions: (1) December 2018, without prior educational intervention (PEI), (2) March 2019, PEI adults, (3) July 2019, PEI in adolescents and children‘s schools, (4) March 2024 long-term evaluation. PEI for adults included in-person lectures, media, and printed materials, for schools (13) lectures, printed materials, and educational video games. Results: 3,025 people were surveyed, with a mean age of 49.9 years (SD ± 14.3); men 46%. Of the total, 52% were sedentary, 47% overweight, and 8% obese, smoking 11%, alcohol consumption 31%, diabetes 7.3%, cholesterol 56.4%, hypertension 32.1%, and CDKC 37%. Comparatively among the records, hypertension: (1) 37.4%, (2) 32.1%, (3) 32.6%, (4) 26.6%. CDKC: (1) 22.1%, (2) 38.6%, (3) 43.4%, and (4) 47%, its correlation with other variables and other risk factors are part of another report. Conclusions: We highlight the positive impact of educational intervention more in schools, evidenced by the increase in knowledge from 22.1% to 43.4% (p&lt;0.001), and the decrease in hypertension from 37.4% to 32.6% (p&lt;0.001). This knowledge increased to 47% in the long-term evaluation, reflected in the lower prevalence of hypertension 26.6%. These two parameters were not as significant with education only in adults, where we usually direct our campaigns, forgetting adolescents and children as the family guiding axis to change the course not only of cardiovascular diseases but also of chronic pathologies.

P019 HYPERTENSION PREVALENCE, HEALTH POLICY, AND GUIDELINES MAPPING: A COMPARATIVE ANALYTIC STUDY ACROSS NINE AFRICAN COUNTRIES 2024

Background: Hypertension, a global burden, increases mortality from cardiovascular and kidney diseases. Worldwide, in 2019, an estimated 1.3 billion adults developed hypertension. In Africa, the cumulative estimated prevalence of hypertension is ∼30.8%. Main Objective: To perform a comparative analysis between African countries focusing on hypertension prevalence, health policy, and guidelines mapping. Methods: A descriptive comparative analytic study compared hypertension data from nine African countries: Eswatini, Ethiopia, Ghana, Kenya, Malawi, Nigeria, Somalia, South Sudan, and Sudan, in 2024. Data included hypertension prevalence, health policy, guidelines’ mapping, and hypertension management responses. Mixed statistical methods of content analysis, percentages, means, and Spearman's correlations were used. Results: Hypertension prevalence varied from 27% in Ethiopia to 43% in Eswatini. Females consistently had higher prevalence than males, 30% in Ethiopia to 47% in Eswatini, suggesting gender-specific risk factors or disparities in healthcare access/utilization. Sudan had the second-highest prevalence 44%. Eswatini implemented strong blood pressure control measures, unlike Sudan. High prevalence was also found in countries with strong policies (Eswatini, Kenya, Nigeria, South Sudan), suggesting urgent improved healthcare delivery, policy enforcement, and addressing other risk factors. Ghana and Somalia had lower hypertension prevalence, though fewer policies. Spearman's test showed strong negative correlations between national responses and hypertension prevalence. Salt Intake Surveys had the strongest negative correlation (-0.707) with hypertension prevalence, highlighting countries like Ethiopia and Malawi with salt intake surveys and lower prevalence, reinforcing dietary factors’ effectiveness in managing hypertension. Kenya, Nigeria, and Ethiopia leverage trained non-physician health workers in hypertension management, thereby, improving treatment access and adherence. Treatment guidelines were moderately negatively correlated (-0.335) with hypertension prevalence. The mere presence of guidelines is insufficient, signifying their implementation and enhancement with targeted interventions Conclusions: These findings highlighted the multifaceted nature of hypertension in African countries which requires comprehensive approaches encompassing considerations of gender, socioeconomic factors, lifestyle, salt reduction, policy implementation, healthcare access, and a unified African hypertension guideline.

P031 SPATIAL ASSOCIATION BETWEEN HYPERTENSION AND AIR POLLUTION IN ULAANBAATAR, MONGOLIA

Background and Objective: This study aims to assess the spatial association between hypertension prevalence and PM2.5 levels in Ulaanbaatar. Methods: To estimate the hypertension prevalence, we conducted a complex survey with a two-stage cluster sampling method in 2018. For PM2.5 level estimation, we used data collected during cold weather months (October to March) from 2015 to 2019. These estimates were used to predict PM2.5 levels across the entire city, using the Inverse Distance Weighted (IDW) interpolation method. The same approach was applied to predict the hypertension prevalence. We fitted a multiple linear regression model to estimate the association between PM2.5 and hypertension prevalence with adjustment for income, a proxy of socioeconomic factors to examine effect modification. In exploratory analysis, we estimated the association between PM2.5 level and income level. We used RStudio 1.3.1093 and ArcMap 10.8.2 for data analysis. Results: A total of 4515 participants were included in the sample. The hypertension prevalence was 46.5% with a threshold of 130/80 mm Hg. Adjusting for other covariates, a 10-unit increase in PM2.5 level is associated with a 6.66 (95% CIs;[10.23,10.23]) point increase in hypertension prevalence (p&lt;0.001). With each 100,000 (MNT) increase in income level, the impact of 10-unit increases in PM2.5 level on hypertension decreases by 2.98 (95% CIs;[-5.48,-0.47]) points (p=0.02). In the partial F-test, an increase in income level was associated with a lower hypertension prevalence (p=0.002). In the exploratory analysis, a 100,000 (MNT) increase in income level was associated with a 0.23 (95% CIs;[-0.41,-0.05]) point decrease in PM2.5 level (p=0.011). Figure 1. Spatial association between hypertension prevalence. A).Hypertension prevalence (%); B).Income level (MNT) PM2.5 level; C).PM 2.5 (μg/m3); D).Linear regression model. Note: Inverse Distance Weighted method is used for predictions. Green points indicate the PM2.5-measuring site locations. Conclusions: The people who live in lower-income areas experience a stronger influence of air pollution on hypertension prevalence compared to others in Ulaanbaatar.

Comparison of four aortic bioprostheses: Hancock II vs. St Jude Trifecta vs. Carpentier-Edwards Perimount Magna vs. Magna Ease-mid-term results (COMPARE SAVR study).

In the era of percutaneous aortic valve implantation, biological valves are the preferred prostheses implanted in patients undergoing surgical aortic valve replacement (sAVR). The aim was to present a real-life analysis of mid-term sAVR outcomes for the four aortic bioprostheses: the Hancock II, the Carpentier-Edwards Perimount Magna, the Carpentier-Edwards Perimount Magna Ease and the Trifecta valve. This is a retrospective study based on data from the Polish National Cardiac Surgery Database. The study population comprised of 1,589 consecutive patients, of whom 432 were in the Hancock II group, 356 in the Carpentier-Edwards Perimount Magna group, 427 in the Carpentier-Edwards Magna Ease group, and 374 in the Trifecta group. A comparison of the four groups was performed using analysis of variance (ANOVA) or Kruskal-Wallis test with appropriate post hoc tests (Tukey HSD or Steel-Dwass, respectively). Patients in the Hancock II group were older, had higher New York Heart Association (NYHA) and Canadian Cardiovascular Society (CCS) classes, had lower prevalence of hypertension and hyperlipidemia but higher prevalence of diabetes. The lowest mean valve size was observed in Trifecta group and the highest was in the Magna group (P<0.001). Survival analysis showed no significant differences in in-hospital mortality: 3.9% in Hancock II, 3.1% in Perimount, 3.3% in Magna and 2.1% in Trifecta group. Five-year mortality was significantly higher in Hancock II group (25.7%) compared to the other bioprostheses: 12.1% in Perimount, 9.1% in Magna and 10.70% in Trifecta group respectively. The 5-year mortality rate was significantly higher in the Hancock II group compared to the other bioprostheses. In contrast, Trifecta, Perimount Magna, and Magna Ease had similar 5-year mortality rates.

Burden of risk factors in women and men with unrecognised myocardial infarction: a systematic review and meta-analysis.

Unrecognised myocardial infarction (MI) is a MI that remains undetected in the acute phase and is associated with an unfavourable prognosis. With this systematic review and meta-analysis, we evaluated the burden of cardiovascular risk factors in individuals with unrecognised MI. We searched general population-based cohort studies diagnosing unrecognised MI by electrocardiogram or myocardial imaging up to 24 November 2023. Pooled mean differences (MD) or risk ratios (RR) with 95% confidence intervals (CI) were determined, and random-effects meta-analyses were performed. Fourteen cohort studies were included involving 200,450 individuals (mean age 62.8±9.9 years, 56.0% women), among which 4,322 (2.2%) experienced unrecognised MI (mean age 66.3±8.2 years, 47.8% women) and 4,653 (2.1%) recognised MI (mean age 68.5±7.3 years, 33.8% women). Compared to individuals without MI, those with unrecognised MI had higher body mass index (MD 0.27, 95% CI 0.16-0.39) and systolic blood pressure (MD 4.48, 95% CI 2.81-6.15), and higher prevalence of hypertension (RR 1.27, 95% CI 1.06-1.51) and diabetes mellitus (RR 1.67, 95% CI 1.36-2.06). Furthermore, individuals with unrecognised MI had lower prevalence of hypertension (RR 0.92, 95% CI 0.88-0.97) and diabetes mellitus (RR 0.80, 95% CI 0.70-0.92). Individuals with unrecognised MI are characterised by a substantial burden of metabolic risk factors. Our findings suggest insufficient recognition and management of cardiovascular risk factors among individuals with unrecognised MI.

Sex-Specific Differences in Kidney Function and Blood Pressure Regulation.

Premenopausal women generally exhibit lower blood pressure and a lower prevalence of hypertension than men of the same age, but these differences reverse postmenopause due to estrogen withdrawal. Sexual dimorphism has been described in different components of kidney physiology and pathophysiology, including the renin-angiotensin-aldosterone system, endothelin system, and tubular transporters. This review explores the sex-specific differences in kidney function and blood pressure regulation. Understanding these differences provides insights into potential therapeutic targets for managing hypertension and kidney diseases, considering the patient's sex and hormonal status.

Retinal Vessel Functional Responses in South Africans Living With and Without HIV: The EndoAfrica-NWU Study.

The effects of HIV and antiretroviral therapy (ART) on microvascular function are poorly explored. We compared retinal vessel functional responses to flicker light-induced provocation (FLIP) in people living with HIV (PLWH) and people living without HIV (PLWoutH). We included 115 PLWH and 51 PLWoutH with a median age of 41 years. Treated PLWH received similar first-line fixed-dose combination ART. Clinical characteristics and retinal vessels functional responses to FLIP were compared in (a) PLWH and PLWoutH; and (b) PLWH groups stratified by the median of (i) CD4-count (511 cells/mm3), (ii) viral load (50 copies/mL), and (iii) ART duration (57.6 months). PLWH were older, smoked more, and had a lower prevalence of hypertension than PLWoutH (p < 0.05). Almost 64% of PLWH were infected for more than 5 years. Retinal vessel responses to FLIP were similar between PLWH and PLWoutH after taking confounders into account. In addition, PLWH subgroups stratified according to immuno-virological status by CD4-count, viral load, and ART duration showed no differences in retinal vessel responses to FLIP. Living with HIV and receiving ART were not associated with altered microvascular function as assessed with dynamic retinal vessel analysis in a South African case-control study.

Global Associations of the Traditional Japanese Diet Score with Hypertension Prevalence and Systolic Blood Pressure from 2009 to 2019: A Cross-Sectional and Longitudinal Ecological Study

Objective Prevention and improvement of hypertension is one of the most important health issues worldwide. The traditional Japanese diet contributes to the prevention of some non-communicable diseases associated with hypertension. However, whether traditional Japanese dietary patterns are associated with hypertension prevalence and systolic blood pressure (SBP) worldwide remains unknown. In this study, we aimed to investigate whether the traditional Japanese diet score (TJDS) is associated with hypertension prevalence and SBP. Methods This cross-sectional and longitudinal ecological study from 2009 to 2019 included 141 countries with a population of at least 1 million. All data used for analysis were obtained from internationally available databases. The TJDS was calculated using country-specific supplies of five foods commonly eaten in the traditional Japanese diet (rice, fish, soybean, vegetables, and egg) and three less commonly eaten foods (wheat, milk, and red meat). Hypertension was defined by SBP ≥140 mmHg, diastolic blood pressure ≥90 mmHg, or use of antihypertensive medications. The mean SBP was >25 age-standardized data. A general linear model was used for the cross-sectional model in 2009, and a linear mixed model was used for the longitudinal analysis from 2009 to 2019. The covariates included gross domestic product, percentage of population aged >65 years, years of education, smoking rate, average body mass index, physical activity, and energy supply. Results The TJDS was negatively associated with hypertension prevalence (β ± standard error: −0.861 ± 0.202, p < 0.001) and SBP (β ± standard error: −0.364 ± 0.154, p < 0.05) in the cross-sectional analysis. The TJDS was significantly negatively associated with hypertension prevalence (β ± standard error: −0.845 ± 0.200, p < 0.001) and SBP (β ± standard error: −0.312 ± 0.149, p < 0.05) in the 10-year longitudinal analysis controlled for full covariables. Conclusions Traditional Japanese dietary patterns are associated with lower hypertension prevalence and SBP worldwide.

Serum vitamin D, blood pressure and hypertension risk in the HUNT study using observational and Mendelian randomization approaches

Limited studies have triangulated the relationship between serum 25-hydroxyvitamin D [25(OH)D] levels and systolic blood pressure (SBP), diastolic blood pressure (DBP) or hypertension risk utilizing both observational and Mendelian randomization (MR) approaches. We employed data from the Norwegian Trøndelag Health Study (HUNT) to conduct cross-sectional (n = 5854) and prospective (n = 3592) analyses, as well as one-sample MR (n = 86,324). We also used largest publicly available data for two-sample MR. Our cross-sectional analyses showed a 25 nmol/L increase in 25(OH)D was associated with a 1.73 mmHg decrease in SBP (95% CI − 2.46 to − 1.01), a 0.91 mmHg decrease in DBP (95% CI − 1.35 to − 0.47) and 19% lower prevalence of hypertension (OR 0.81, 95% CI 0.74 to 0.90) after adjusting for important confounders. However, these associations disappeared in prospective analyses. One-sample and two-sample MR results further suggested no causal relationship between serum vitamin D levels and blood pressure or hypertension risk in the general population.

Serum 25-Hydroxyvitamin D Level Is Positively Associated with Vascular Reactivity Index in Patients with Type 2 Diabetes Mellitus.

Circulating 25-hydroxyvitamin D (25(OH)D) significantly influences endothelial function. This study assessed the correlation between serum 25(OH)D and endothelial function using the vascular reactivity index (VRI) in patients with type 2 diabetes mellitus (T2DM). Fasting blood samples from 102 T2DM participants and VRI were assessed. Patients were divided into three categories based on VRI: low (VRI < 1.0), intermediate (1.0 ≤ VRI < 2.0), and good (VRI ≥ 2.0). Among these patients, 30 (29.4%) had poor, 39 (38.2%) had intermediate, and 33 (32.4%) exhibited good vascular reactivity. Higher serum fasting glucose (p = 0.019), glycated hemoglobin (p = 0.009), and urinary albumin-to-creatinine ratio (p = 0.006) were associated, while lower prevalence of hypertension (p = 0.029), lower systolic blood pressure (p = 0.027), lower diastolic blood pressure (p < 0.001), and lower circulation 25(OH)D levels (p < 0.001) were associated with poor vascular reactivity. Significant independent associations between diastolic blood pressure (p = 0.002) and serum 25(OH)D level (p < 0.001) and VRI were seen in T2DM patients according to multivariable forward stepwise linear regression analysis. Serum 25(OH)D positively correlated with VRI values, and lower levels of serum 25(OH)D were linked to endothelial dysfunction in T2DM patients.

Regional and rural-urban patterns in the prevalence of diagnosed hypertension among older U.S. adults with diabetes, 2005–2017

BackgroundHypertension prevalence among the overall US adult population has been relatively stable during the last two decades. However, whether this stabilization has occurred across rural-urban communities and across different geographic regions is unknown, particularly among older adults with diabetes who are likely to have concomitant cardiovascular risk factors.MethodsThis serial cross-sectional analysis used the 5% national sample of Medicare administrative claims data (n = 3,516,541) to examine temporal trends (2005–2017) in diagnosed hypertension among older adults with diabetes, across urban-rural communities and US census regions (Northeast, Midwest, South, and West). Joinpoint regression was used to obtain annual percent change (APC) in hypertension prevalence across rural-urban communities and geographic regions, and multivariable adjusted regression was used to assess associations between rural-urban communities and hypertension prevalence.ResultsThe APC in the prevalence of hypertension was higher during 2005–2010, and there was a slowdown in the increase during 2011–2017 across all regions, with significant variations across rural-urban communities within each of the regions. In the regression analysis, in the adjusted model, older adults living in non-core (most rural) areas in the Midwest (PR = 0.988, 95% CI: 0.981–0.995) and West (PR = 0.935, 95% CI: 0.923–0.946) had lower hypertension prevalence than their regional counterparts living in large central metro areas.ConclusionsAlthough the magnitudes of these associations are small, differences in hypertension prevalence across rural-urban areas and geographic regions may have implications for targeted interventions to improve chronic disease prevention and management.

Short-Term Outcomes of Transcatheter Aortic Valve Replacement in Low-Risk Patients With Pure Severe Aortic Regurgitation

Transcatheter aortic valve replacement (TAVR) has emerged as an alternative treatment for patients with pure severe aortic regurgitation (PSAR) who are contraindicated for surgery or have a high surgical risk. However, the therapeutic efficacy and safety of TAVR in low Society of Thoracic Surgeons (STS) score risk patients remain to be clarified. This study aimed to explore the feasibility of TAVR treatment in different STS-risk patients and to compare the adverse events between the groups. In this study, patients with PSAR who underwent TAVR at Zhongshan Hospital, Fudan University, China, during the inclusion period were included and categorized into 3 groups based on STS scores. The baseline data, imaging results, and follow-up data of the patients were documented. Therefore, of 75 TAVR patients, 38 (50.7%) were categorized as low risk (STS <4), and 37 (49.3%) patients were categorized as intermediate and high risk (STS ≥4). Compared with patients at intermediate and high risk, those in the low-risk group were younger, had a lower body mass index, had a lower prevalence of hypertension, chronic obstructive pulmonary disease, and previous percutaneous coronary intervention, and had better cardiac function (p all <0.05). In the hospital and at the 1-month follow-up, the degree of aortic regurgitation and cardiac function were significantly improved. No significant difference was found between the 2 groups in the hospital or during the 30-day follow-up. In conclusion, TAVR for PSAR in low-STS-risk patients is safe and efficient during 30 days of follow-up compared with intermediate- and high-STS-risk groups. TAVR for PSAR should not be limited to inoperable or STS-defined high-risk patients. Long-term follow-up is needed for further investigation.

Metabolic dysfunction-associated steatotic liver disease in people with HIV is associated with lower BMI and more liver fibrosis compared to the uninfected population

Aim: People with HIV (PWH) are at high risk of metabolic dysfunction-associated steatotic liver disease (MASLD), defined by the presence of hepatic steatosis plus any among overweight, diabetes, hypertension, or dyslipidemia. There are limited data whether MASLD in PWH differs in clinical presentation from MASLD in the uninfected population. Aim: to compare the severity of metabolic and hepatic dysfunction between MASLD patients with and without HIV. Methods: 212 consecutive HIV mono-infected patients with MASLD at McGill University in Montreal were compared to a sex and age matched MASLD HIV negative control group at Policlinico Hospital in Milan. Fibroscan with controlled attenuation parameter (CAP) was used to define MASLD (CAP≥248 dB/m), severe MASLD (CAP&gt;280 dB/m), and significant liver fibrosis (liver stiffness measurement&gt;7.0 kPa). Results: PWH with MASLD presented lower median BMI (28[25-31] vs 29[27-32] Kg/m2, p=0.002) and lower prevalence of obesity (26% vs 44%, p&lt;0.001) compared to MASLD uninfected patients, along with a lower prevalence of hypertension (21% vs 38%, p&lt;0.001). The prevalence of dyslipidemia (41% vs 26%, p&lt;0.001), hypertriglyceridemia (26% vs 9%, p&lt;0.001) and low HDL cholesterol (34% vs 15%, p&lt;0.001) was higher in MASLD patients with vs without HIV. No difference in cardiovascular events and diabetes prevalence was observed between the two groups. Regarding liver disease, PWH with MASLD had lower prevalence of severe MASLD (54% vs 74% p&lt;0.001) but higher prevalence of significant liver fibrosis (15 vs 7%, p=0.03) compared to MASLD uninfected patients. After adjustment, HIV positivity was an independent factor associated with significant liver fibrosis (figure). Conclusions: Despite having lower BMI, PWH with MASLD have a more severe hepatic presentation and atherogenic lipid profile than MASLD uninfected patients. HIV positivity seems to be independently associated with significant liver fibrosis. Screening and follow-up for MASLD and liver fibrosis is recommended in PWH, even if they are lean.

Evaluation of Myo-Intimal Media Thickness and Atheromatous Plaques in People Living with HIV from the Archiprevaleat Cohort vs. HIV-Negative Subjects.

Antiretroviral therapy has allowed a clear improvement in prognosis for HIV patients, but metabolic problems, such as dyslipidemia, remain. This can lead to the development of atheromatous plaques. Our study aims to evaluate whether HIV-positive (HIV+) patients show higher myo-intimal media thickness (IMT) and atheromatous plaques compared to HIV-negative (HIV-) patients. To evaluate the association between HIV infection in experienced patients and vascular pathology, we performed a cross-sectional study, observing 1006 patients, 380 HIV+ enrolled in the Archiprevaleat cohort, and 626 HIV- as a control group. All patients underwent a Doppler scan of the supra-aortic vessels. We compared the prevalence of IMT > 1.0 mm and plaques in the two groups. Patients in the HIV+ group were younger than those in the HIV- group, with a lower prevalence of hypertension and diabetes and higher dyslipidemia. The prevalence of plaques in strata of age was higher in the HIV+ group than in the HIV- group and was associated with the length of ART exposure. Our cross-sectional, retrospective study shows that HIV+ experienced patients are at greater risk of IMT and atheromatous plaques compared to HIV-. The risk is associated with being HIV+ and with the length of ART exposure. This finding may be useful in preventing cardiovascular risk.

Residential variations in hypertension prevalence and trends among adults in Bangladesh

IntroductionHypertension is a widespread and life-threatening condition globally, with its prevalence increasing rapidly, particularly among adults. This study aims to examine the trend in adult hypertension prevalence and associated risk factors in both urban and rural areas of Bangladesh from 2011 to 2018.MethodsNationally representative cross-sectional data from the Bangladesh Demographic and Health Survey was used at two time points, 2011 and 2018. In our study, we used a two-step approach for variable selection, combining traditional statistical methods (χ2\\documentclass[12pt]{minimal} \\usepackage{amsmath} \\usepackage{wasysym} \\usepackage{amsfonts} \\usepackage{amssymb} \\usepackage{amsbsy} \\usepackage{mathrsfs} \\usepackage{upgreek} \\setlength{\\oddsidemargin}{-69pt} \\begin{document}$${\\chi }^{2}$$\\end{document} test) with a machine learning algorithm (Boruta algorithm).. This study also employed two different multivariate binary logistic regression models to identify the risk factors that are most closely connected to the presence of hypertension (respectively for urban and rural locations).ResultsAccording to the study, hypertension has been on the rise in Bangladesh. In 2011, over a third of adults (38.7%) in urban Bangladesh had hypertension, a number that rose by 22.6% in 2017-18. Though rural areas had a lower hypertension prevalence in 2011 (36%), it surged to 64% in 2017-18, surpassing the rate in urban areas. The results of the multivariate analysis showed that age, gender, education, wealth status, area, and survey year had a significant influence on the determinants of hypertension status in connection to place of residence. According to the odds ratio, the prevalence was significantly higher among older respondents, female respondents, wealthy families and higher-educated respondents.ConclusionA large proportion of Bangladesh’s adult population suffers from hypertension. A health education program is required to develop appropriate strategies, including appropriate weight control, appropriate physical activity, and healthier eating habits. Health authorities should take initiatives to spread awareness among people, particularly at an older age.

Association of thyroid autoimmunity with extra-thyroid diseases and the risk of mortality among adults: evidence from the NHANES.

Thyroid autoimmunity is one of the most prevalent autoimmune diseases. However, its association with extra-thyroid diseases and mortality risk in the general population remains uncertain. Our study aims to evaluate the association of thyroid autoimmunity with extra-thyroid disease and the risk of mortality. A prospective cohort study was conducted using data from the National Health and Nutrition Examination Survey (NHANES) with participants from 2007-2008, 2009-2010, and 2011-2012, tracking their mortality until 2019. Associations between thyroid autoimmunity, which was defined as having positive thyroid peroxidase antibody (TPOAb) and/or thyroglobulin antibody (TgAb), and extra-thyroid disease including diabetes, hypertension, cardiovascular disease, chronic lung disease, arthritis, cancer and chronic renal disease and the risk of mortality were investigated. A total of 7431 participants were included in this study. Positive The prevalence of positive TgAb was 7.54%, and positive TPOAb prevalence was 11.48%. TgAb was significantly associated with diabetes (Model 1: OR=1.64, 95% CI:1.08-2.50; Model 2: OR=1.93, 95% CI: 1.21-3.08) and hypertension (Model 1: OR=0.67, 95% CI: 0.49-0.91; Model 2: OR=0.62, 95% CI: 0.44-0.88). TPOAb was associated with a lower prevalence of chronic lung disease (model 1: OR=0.71, 95% CI: 0.54-0.95; model 2: OR=0.71, 95% CI: 0.53-0.95). No associations were observed between TgAb, TPOAb and other extra-thyroid diseases. Neither TgAb nor TPOAb were associated with all-cause mortality or heart disease mortality. TgAb was linked to a higher prevalence of diabetes and a lower prevalence of hypertension, while TPOAb was associated with a decreased prevalence of chronic lung disease. However, neither TgAb nor TPOAb posed a risk for all-cause mortality or heart disease mortality.
