Women with Blood Pressure Improvement in the Well-Integrated Screening and Evaluation for Women Across the Nation Program by Race and Ethnicity, 2014-2018.

Background: The Well-Integrated Screening and Evaluation for Women Across the Nation (WISEWOMAN) program aims to improve the cardiovascular health of women aged 40-64 years with low incomes, and who are uninsured or underinsured. The objective is to examine WISEWOMAN participants with hypertension who had high blood pressure (BP) improvement from January 2014 to June 2018, by race and ethnicity. Also examined was participation in WISEWOMAN Healthy Behavior Support Services (HBSS) and adherence to antihypertensive medication. Materials and Methods: WISEWOMAN data from January 2014 to June 2018 were analyzed by race and ethnicity. BP improvement was defined as at least a 5 mm Hg decrease in systolic or diastolic BP values from baseline screening to rescreening. The prevalence of HBSS participation and antihypertensive medication adherence were calculated among hypertensive women with BP improvement. Results: Approximately 64.2% (4,984) of WISEWOMAN participants with hypertension had at least a 5 mm Hg BP improvement. These improvements were consistent across each race and ethnicity (p = 0.56) in the study. Nearly 70% of women who had BP improvement attended at least one HBSS. Hispanic women (80.1%) had the highest HBSS attendance percentage compared to non-Hispanic Black women (64.1%) and non-Hispanic White women (63.8%; p < 0.001). About 80% of women with BP improvement reported being adherent to antihypertensive medication in the previous 7 days. Conclusions: The proportion of women achieving BP improvement in the WISEWOMAN program was consistent across race and ethnicity. In addition, women with BP improvement reported adherence to antihypertensive medication and participation in HBSS.

Health Social Networks of Black Women With Hypertension.

BACKGROUND: The prevalence of hypertension is 55% among African American/Black women, who have a higher risk for poor health outcomes compared to women from other racial and ethnic groups, in part because of uncontrolled blood pressure. Previous research results suggest that peers may positively influence self-management of chronic conditions like hypertension. However, few studies have described the personal characteristics of peers in the health social networks of Black women. OBJECTIVE: This substudy aimed to examine health social networks and describe the peers' characteristics, as reported by a convenience sample of Black women with hypertension. METHODS: In this analysis of data from a larger study, 94 Black women with hypertension attending a church conference participated in a cross-sectional, descriptive study. Their mean age was 59 years, and their mean systolic blood pressure was 143 mm Hg. All participants completed a survey to gather data about (a) the characteristics of individuals they discussed health matters with (their peers or health social network) and (b) their perceptions about hypertension status and knowledge of hypertension among the peers in their health social network. RESULTS: Collectively, participants from the larger study named a total of 658 peers who were part of their health social networks; the mean health social network size was six peers. The peers were mostly women, Black, family members, and, on average, 54 years old. The participants discussed hypertension with 71% of the peers, reported that 36% had hypertension, and felt that 67% were somewhat or very knowledgeable about the condition. A small, positive correlation existed between the participants' health social network size (number of peers named) and their systolic blood pressure levels. DISCUSSION: The health social network peers were similar to those in the larger study, with most of the same gender, race, and age. The findings of this analysis may be used to help practitioners and scientists guide patients in building health social networks for support in self-managing hypertension and conducting future studies to examine the best strategies for developing and using health social networks to improve health outcomes and reduce health disparities.

Triglyceride glucose index and renal function decline in Han Chinese hypertensive patients.

Elevated triglyceride glucose (TyG) index is associated with an increased risk of cardiovascular disease. The current study aimed to investigate whether the TyG index was correlated with renal function decline in patients with hypertension. Han Chinese participants with essential hypertension were included. The TyG index was calculated as ln[fasting triglycerides (mg/dL) * fasting glucose (mg/dL)/2]. Renal function decline was defined as >25% decline in estimated glomerular filtration rate (eGFR). The Cox proportional hazard regression model was used to examine the independent effect of the TyG index on renal events. In total, 548 Han Chinese hypertensive participants with a mean age of 62.1 ± 14.3 years were eligible for enrollment. During a mean follow-up period of 4.7 ± 3.1 years, 97 patients suffered from >25% decline in eGFR. When compared to those without eGFR decline, patients with eGFR decline had higher fasting triglyceride levels (P = .056), fasting glucose levels (P = .014), and TyG indexes (P = .014). The Cox proportional hazard regression model revealed that the TyG index (hazard ratio [HR] = 1.490; 95% confidence interval [CI] = 1.016-2.185, P = .041), office systolic blood pressure (HR = 1.013; 95% CI = 1.000-1.026, P = .047), diabetes mellitus (HR = 1.797, 95% CI = 1.026-3.147, P = .040), and baseline eGFR (HR = 1.015; 95% CI = 1.002-1.028, P = .025) were associated with renal events. In conclusions, an elevated TyG index is independently associated with an increased risk of eGFR decline in hypertensive patients.

Using Community-Based Participatory Research Methods to Inform the Development of Medically Tailored Food Kits for Hispanic/Latine Adults with Hypertension: A Qualitative Study.

The Dietary Approaches to Stop Hypertension (DASH) eating plan is the most effective dietary intervention for cardiovascular disease (CVD), but it excludes the consideration of culture and cost. The Hispanic/Latine population is disproportionately affected by CVD, with risks increasing if persons are accustomed to a Westernized diet. This research aims to understand the cultural dietary practices aligned with a DASH eating plan and the social determinants of health impacting fruit and vegetable (F/V) consumption among immigrant Hispanic/Latine individuals at a community-based clinic in Minnesota. Utilizing community-based participatory research methods, a community survey informed the development of DASH-focused, medically tailored food kits of varying F/V modalities. Qualitative feedback was sought out regarding the kits when presented to 15 individuals during in-depth interview sessions to validate the cultural appropriateness of food kits for clinical use. Box A was the highest rated kit (66.7%) and consisted of fresh F/V. The average F/V consumption per day was 2.6 ± 1.4 servings. The food insecurity questionnaires showed high/marginal (40%), low (53.3%), and very low (6.7%) food security. The barriers to consuming F/V were money, time, and transportation. Understanding cultural dietary practices related to the DASH eating plan is necessary to mitigate CVD risk and provide inclusive medical nutrition therapy for Hispanic/Latine populations.

Evaluating the Impact of the Prime Time Sister Circles® Intervention on Reducing Depressive Symptoms Among African American Women with Uncontrolled Hypertension.

BACKGROUND: The Prime Time Sister Circles®, a randomized controlled trial (PTSC-RCT), assessed the impact of a community-based peer support program on hypertension management among African American women 40-75 years of age. While the PTSC-RCT was designed to evaluate changes in blood pressure control, subsequent sub-analyses revealed a high proportion of self-reported depressive symptoms in our sample. Accordingly, we conducted an ancillary investigation of the PTSC intervention on depression to ascertain its impact on reduced depressive symptoms in the study population. METHOD: Depressive symptoms were measured using an adapted version of the Center for Epidemiologic Studies Depression Scale Revised (CES-D-10). We used unadjusted and adjusted fixed effect models. Data for this study came from the PTSC-RCT. We collected data between 2017 and 2018 in Washington, DC. We used a balanced analytical sample of 172 African American, English-speaking women between 40 to 75 years old with uncontrolled hypertension. INTERVENTION: The intervention group participated in a 2-h, peer-based support group once a week for 13 weeks. A trained PTSC facilitator facilitated sessions with experts who delivered content on various topics, including psychosocial wellness (e.g., stress, depressive symptoms, anxiety management, and self-esteem), physical health (e.g., hypertension, inflammation, and heart disease), physical activity, and healthy nutrition. RESULTS: Results from the fixed-effects models indicated that participants in the PTSC program exhibited a greater reduction in CES-D-10 score at three months (Coeff: -1.99, 95% CI: -3.49, -0.49) and at 15 months (Coeff: -2.38, 95% CI: -3.94, -0.83), as compared to those in the control group. CONCLUSIONS: Evidence suggests that the Prime Time Sister Circles® intervention reduced depressive symptoms among African American women with low socioeconomic status and hypertension. TRIAL REGISTRATION: NCT04371614.

The design and rationale of a multicenter real-world trial: The Southeastern Collaboration to Improve Blood Pressure Control in the US Black Belt - Addressing the Triple Threat.

BACKGROUND: Impoverished African Americans (AA) with hypertension face poor health outcomes. PURPOSE: To conduct a cluster-randomized trial testing two interventions, alone and in combination, to improve blood pressure (BP) control in AA with persistently uncontrolled hypertension. METHODS: We engaged primary care practices serving rural Alabama and North Carolina residents, and in each practice we recruited approximately 25 AA adults with persistently uncontrolled hypertension (mean systolic BP >140 mmHg over the year prior to enrollment plus enrollment day BP assessed by research assistants ≥140/90 mmHg). Practices were randomized to peer coaching (PC), practice facilitation (PF), both PC and PF (PC + PF), or enhanced usual care (EUC). Coaches met with participants from PC and PC + PF practices weekly for 8 weeks then monthly over one year, discussing lifestyle changes, medication adherence, home monitoring, and communication with the healthcare team. Facilitators met with PF and PC + PF practices monthly to implement ≥1 quality improvement intervention in each of four domains. Data were collected at 0, 6, and 12 months. RESULTS: We recruited 69 practices and 1596 participants; 18 practices (408 participants) were randomized to EUC, 16 (384 participants) to PF, 19 (424 participants) to PC, and 16 (380 participants) to PC + PF. Participants had mean age 57 years, 61% were women, and 56% reported annual income <$20,000. LIMITATIONS: The PF intervention acts at the practice level, possibly missing intervention effects in trial participants. Neither PC nor PF currently has established clinical reimbursement mechanisms. CONCLUSIONS: This trial will fill evidence gaps regarding practice-level vs. patient-level interventions for rural impoverished AA with uncontrolled hypertension.

[Factors associated with inequalities in social conditions in the health of elderly white, brown and black people in the city of São Paulo, Brazil]. / Fatores associados às desigualdades das condições sociais na saúde de idosos brancos, pardos e pretos na cidade de São Paulo, Brasil.

The scope of this study is to identify determining factors of disparities in social conditions in the health of non-institutionalized elderly people in the city of São Paulo, from the standpoint of self-declaration of skin color. It is a cross-sectional study with a representative sample of 1,017 elderly participants in the "2015 Health Survey of the Municipality of São Paulo". The analysis used crude and adjusted Poisson regression models, reporting the prevalence ratio and 95% confidence intervals as a measure of association between the variables. In the adjusted analysis, brown and black skin color was positively associated with worse schooling, negative self-assessment of health status, health insurance and access to public health services. On the one hand, black skin color was no longer associated with the lowest income, however, it was associated with arterial hypertension. On the other hand, brown skin color was associated with low income, but not with arterial hypertension. Elderly black and brown people had worse health conditions, less access to private health services and socioeconomic resources. These results are compatible with the hypothesis of structural racism in São Paulo's society and may inform social health policies aimed at promoting health and social justice.

O objetivo deste estudo é identificar fatores determinantes das disparidades das condições sociais na saúde de idosos não institucionalizados na cidade de São Paulo, sob a perspectiva da autodeclaração da cor da pele. Estudo transversal com amostra representativa de 1.017 idosos participantes do "Inquérito de Saúde do Município de São Paulo 2015". A análise utilizou modelos de regressão de Poisson brutas e ajustadas, relatando a razão de prevalências e seus intervalos de 95% de confiança como medida de associação entre as variáveis. Na análise ajustada, a cor da pele parda e preta associou-se, positivamente, com a pior escolaridade, a autoavaliação do estado de saúde negativa, o plano de saúde e o acesso ao serviço de saúde público. De um lado, a cor da pele preta perdeu a associação com a pior renda, no entanto, associou-se com a hipertensão arterial. De outro lado, a cor da pele parda não se associou com a hipertensão arterial, mas com a renda baixa. Idosos pretos e pardos tiveram menos acesso a recursos socioeconômicos, às piores condições de saúde e, também, a serviços de saúde privados. Esses resultados são compatíveis com a hipótese de racismo estrutural na sociedade paulistana e podem instruir políticas sociais na saúde dirigidas à promoção de saúde e justiça social.

Ethnic differences in blood pressure levels over time: the HELIUS study.

AIMS: Hypertension is an important global health burden with major differences in prevalence among ethnic minorities compared with host populations. Longitudinal research on ethnic differences in blood pressure (BP) levels provides the opportunity to assess the efficacy of strategies aimed at mitigating gaps in hypertension control. In this study, we assessed the change in BP levels over time in a multi-ethnic population-based cohort in Amsterdam, the Netherlands. METHODS AND RESULTS: We used baseline and follow-up data from HELIUS to assess differences in BP over time between participants of Dutch, South Asian Surinamese, African Surinamese, Ghanaian, Moroccan, and Turkish descent. Baseline data were collected between 2011 and 2015 and follow-up data between 2019 and 2021. The main outcome was ethnic differences in systolic BP (SBP) over time determined by linear mixed models adjusted for age, sex, and use of antihypertensive medication. We included 22 109 participants at baseline, from which 10 170 participants had complete follow-up data. The mean follow-up time was 6.3 (1.1) years. Compared with the Dutch population, the mean SBP increased significantly more from baseline to follow-up in Ghanaians [1.78 mmHg, 95% confidence interval (CI) 0.77-2.79], Moroccans (2.06 mmHg, 95% CI 1.23-2.90), and the Turkish population (1.30 mmHg, 95% CI 0.38-2.22). Systolic blood pressure differences were in part explained by differences in body mass index (BMI). No differences in SBP trajectory were present between the Dutch and Surinamese population. CONCLUSION: Our findings indicate a further increase of ethnic differences in SBP among Ghanaian, Moroccan, and Turkish populations compared with the Dutch reference population that are in part attributable to differences in BMI.

In this study, we assessed ethnic differences in blood pressure (BP) over time in participants living in Amsterdam, the Netherlands.We found a further increase of systolic BP (SBP) and hypertension prevalence among Ghanaian, Moroccan, and Turkish populations compared with the Dutch reference population. No differences in SBP trajectory were present between the Dutch and Surinamese population.Differences in SBP were in part explained by differences in body mass index. Further action needs to be taken to utilize this information to improve cardiovascular health management in multi-ethnic populations.

Cardiovascular Risk Factor Prevalence, Treatment, and Control in US Adults Aged 20 to 44 Years, 2009 to March 2020.

Importance: Declines in cardiovascular mortality have stagnated in the US over the past decade, in part related to worsening risk factor control in older adults. Little is known about how the prevalence, treatment, and control of cardiovascular risk factors have changed among young adults aged 20 to 44 years. Objective: To determine if the prevalence of cardiovascular risk factors (hypertension, diabetes, hyperlipidemia, obesity, and tobacco use), treatment rates, and control changed among adults aged 20 to 44 years from 2009 through March 2020, overall and by sex and race and ethnicity. Design, Setting, and Participants: Serial cross-sectional analysis of adults aged 20 to 44 years in the US participating in the National Health and Nutrition Examination Survey (2009-2010 to 2017-March 2020). Main Outcomes and Measures: National trends in the prevalence of hypertension, diabetes, hyperlipidemia, obesity, and smoking history; treatment rates for hypertension and diabetes; and blood pressure and glycemic control in those receiving treatment. Results: Among 12 924 US adults aged 20 to 44 years (mean age, 31.8 years; 50.6% women), the prevalence of hypertension was 9.3% (95% CI, 8.1%-10.5%) in 2009-2010 and 11.5% (95% CI, 9.6%-13.4%) in 2017-2020. The prevalence of diabetes (from 3.0% [95% CI, 2.2%-3.7%] to 4.1% [95% CI, 3.5%-4.7%]) and obesity (from 32.7% [95% CI, 30.1%-35.3%] to 40.9% [95% CI, 37.5%-44.3%]) increased from 2009-2010 to 2017-2020, while the prevalence of hyperlipidemia decreased (from 40.5% [95% CI, 38.6%-42.3%] to 36.1% [95% CI, 33.5%-38.7%]). Black adults had high rates of hypertension across the study period (2009-2010: 16.2% [95% CI, 14.0%-18.4%]; 2017-2020: 20.1% [95% CI, 16.8%-23.3%]), and significant increases in hypertension were observed among Mexican American adults (from 6.5% [95% CI, 5.0%-8.0%] to 9.5% [95% CI, 7.3%-11.7%]) and other Hispanic adults (from 4.4% [95% CI, 2.1%-6.8%] to 10.5% [95% CI, 6.8%-14.3%]), while Mexican American adults had a significant rise in diabetes (from 4.3% [95% CI, 2.3%-6.2%] to 7.5% [95% CI, 5.4%-9.6%]). The percentage of young adults treated for hypertension who achieved blood pressure control did not significantly change (from 65.0% [95% CI, 55.8%-74.2%] in 2009-2010 to 74.8% [95% CI, 67.5%-82.1%] in 2017-2020], while glycemic control among young adults receiving treatment for diabetes remained suboptimal throughout the study period (2009-2010: 45.5% [95% CI, 27.7%-63.3%]) to 2017-2020: 56.6% [95% CI, 39.2%-73.9%]). Conclusions and Relevance: In the US, diabetes and obesity increased among young adults from 2009 to March 2020, while hypertension did not change and hyperlipidemia declined. There was variation in trends by race and ethnicity.

Social Determinants, Blood Pressure Control, and Racial Inequities in Childbearing Age Women With Hypertension, 2001 to 2018.

Background Hypertension is an important modifiable risk factor of serious maternal morbidity and mortality. Social determinants of health (SDoH) influence hypertension outcomes and may contribute to racial and ethnic differences in hypertension control. Our objective was to assess SDoH and blood pressure (BP) control by race and ethnicity in US women of childbearing age with hypertension. Methods and Results We studied women (aged 20-50 years) with hypertension (systolic BP ≥140 mm Hg or diastolic BP ≥90 mm Hg or use of antihypertensive medication) in the National Health and Nutrition Examination Surveys 2001 to 2018. SDoH and BP control (systolic BP <140 mm Hg and diastolic BP <90 mm Hg) were examined by race and ethnicity (White race, Black race, Hispanic ethnicity, and Asian race). Using multivariable logistic regression, odds of uncontrolled BP by race and ethnicity were modeled, adjusting for SDoH, health factors, and modifiable health behaviors. Responses on hunger and affording food determined food insecurity status. Across women of childbearing age with hypertension (N=1293), 59.2% were White race, 23.4% were Black race, 15.8% were Hispanic ethnicity, and 1.7% were Asian race. More Hispanic and Black women experienced food insecurity than White women (32% and 25% versus 13%; both P<0.001). After SDoH, health factor, and modifiable health behavior adjustment, Black women maintained higher odds of uncontrolled BP than White women (odds ratio, 2.31 [95% CI, 1.08-4.92]), whereas Asian and Hispanic women showed no difference. Conclusions We identified racial inequities in uncontrolled BP and food insecurity among women of childbearing age with hypertension. Further exploration beyond the SDoH measured is needed to understand the inequity in hypertension control in Black women.

Disparities in absolute cardiovascular risk, metabolic syndrome, hypertension, and other risk factors by income within racial/ethnic groups among middle-aged and older US people.

This cross-sectional study determined income disparities in age-adjusted prevalence and trends of 10-year high absolute cardiovascular disease (CVD) risk, metabolic syndrome, hypertension, diabetes, obesity, chronic kidney disease (CKD), leisure-time physical activity (LTPA), and current tobacco smoking within racial/ethnic groups in the US. National Health and Nutrition Examination Survey 2001-2016 data of 40-79-year-old people were analyzed. Survey periods were grouped as 2001-2006, 2007-2012, and 2013-2016. Race/ethnicity was grouped as non-Hispanic whites, non-Hispanic blacks, and other races/ethnicities. Three equal-sized strata (low-, middle-, and high income) were made from the family income-to-poverty ratio. Of the 25,777 participants (mean age: 55.6 years, 48% males), a majority of the studied prevalence was higher in most survey years among non-Hispanic blacks compared to non-Hispanic whites. Most studied prevalence was also higher among low-income people than middle-/high-income people. Within racial/ethnic groups, the prevalence also differed by income for high CVD risk, metabolic syndrome, hypertension, diabetes, obesity, CKD, LTPA, and tobacco smoking (P < 0.05) in most survey periods. After stratifying by race/ethnicity, the prevalence of many conditions remained disproportionately higher among low- and middle-income people, compared to those with high income during most survey periods in all racial/ethnic groups. These results reveal income in addition to race/ethnicity to be an important correlate of cardiovascular health and underscore the need to consider each when controlling for risk factors.

Lethal Police Encounters and Cardiovascular Health among Black Americans.

This study uses insights from social stress theory to examine associations between exposure to police killings of Black Americans and cardiovascular health among Black women and men. Data on lethal police encounters come from the Mapping Police Violence (MPV) database, which allows for examination of total exposures to police killings of Black people and exposures to events when decedents were unarmed. MPV data are merged with the Behavioral Risk Factor Surveillance System (n = 26,086) and state-level information from multiple federal databases. Four cardiovascular health outcomes are examined-hypertension, diabetes, heart attack, and stroke. After adjusting for important risk factors, results from gender-stratified multilevel logistic regressions reveal a positive association between exposures to police killings of unarmed Black people and odds of hypertension among Black women and stroke among Black men. Total exposures to police killings of Black people are also associated with greater likelihood of stroke for Black men. Findings from this study demonstrate that stress exposures generated by the quantity and injustice of police killings have important implications for cardiovascular health among Black Americans. Furthermore, adverse cardiovascular health associated with exposure to police violence tends to manifest differently for Black men and women.

Efficacy of a single dose of esmolol to prevent extubation-related complications during emergence from anesthesia: a randomized, double-blind, placebo-controlled trial

Abstract Background Few trials have examined the efficacy of esmolol to attenuate hemodynamic and respiratory responses during extubation. However, the most appropriate dose of esmolol and an optimal protocol for administering this beta-blocker are uncertain. Methods Ninety patients ASA physical status I, II, and III (aged 18-60 years) scheduled to procedures with general anesthesia and tracheal extubation were selected. Patients were randomized into esmolol and placebo group to evaluate the efficacy and safety of a single bolus dose of esmolol (2 mg.kg-1) on cardiorespiratory responses during the peri-extubation period. The primary outcome was the rate of tachycardia during extubation. Results The rate of tachycardia was significantly lower in esmolol-treated patients compared to placebo-treated patients (2.2% vs. 48.9%, relative risk (RR): 0.04, 95% confidence interval (95% CI) = 0.01 to 0.32, p= 0.002). The rate of hypertension was also significantly lower in the esmolol group (4.4% vs. 31.1%, RR: 0.14, 95% CI 0.03 to 0.6, p= 0.004). Esmolol-treated patients were associated with higher extubation quality compared to patients who received placebo (p< 0.001), with an approximately two-fold increase in the rate of patients without cough (91.1%) in the esmolol group compared to the placebo group (46.7%). The rate of bucking was approximately 5-fold lower in the esmolol group (8.9% vs. 44.5%, respectively, RR: 0.20 (95% CI, 0.1 to 0.5, p= 0.002, with an NNT of 2.8). Conclusion A single bolus dose of esmolol is an effective and safe therapeutic strategy to attenuate cardiorespiratory responses during the peri-extubation period.

SNPs in lncRNA KCNQ1OT1 Modulate Its Expression and Confer Susceptibility to Salt Sensitivity of Blood Pressure in a Chinese Han Population.

Long noncoding RNA (lncRNA) plays an important role in cardiovascular diseases, but the involvement of lncRNA in salt sensitivity of blood pressure (SSBP) is not well-known. We aimed to explore the association of sixteen single-nucleotide polymorphisms (SNPs) in five lncRNA genes (KCNQOT1, lnc-AGAP1-8:1, lnc-IGSF3-1:1, etc.) with their expression and susceptibility to SSBP. A two-stage association study was conducted among 2057 individuals. Quantified expression of the lncRNA was detected using real-time PCR. Genotyping was accomplished using the MassARRAY System. The expression quantitative tra2it loci test and the generalized linear model were utilized to explore the function of SNPs. One-sample Mendelian randomization was used to study the causal relationship between KCNQOT1 and SSBP. Significant effects were observed in KCNQ1OT1 expressions on the SSBP phenotype (p < 0.05). Rs10832417 and rs3782064 in KCNQ1OT1 may influence the secondary structure, miRNA binding, and expression of KCNQ1OT1. Rs10832417 and rs3782064 in KCNQ1OT1 were identified to be associated with one SSBP phenotype after multiple testing corrections and may be mediated by KCNQ1OT1. One-sample Mendelian randomization analyses showed a causal association between KCNQ1OT1 and SSBP. Our findings suggest that rs10832417 and rs3782064 might be associated with a lower risk of SSBP through influencing the KCNQ1OT1 secondary structure and miRNA binding, resulting in changes in KCNQ1OT1 expression.

9p21 Locus Polymorphisms: Risk and Severity Factors of Coronary Artery Disease in Venezuelan Patients

Abstract Background: The 9p21 region is the most relevant locus associated with coronary heart disease in different populations. However, there are no studies that prove that this region is a risk factor in the Venezuelan population. Objectives: To analyze whether or not the 9p21 rs1333049 polymorphism is a risk factor for acute myocardial infarction (AMI) in Venezuelan patients, as well as to investigate its correlation with cardiovascular risk factors (CVRF), age of occurrence, type and severity of infarction, and the correlation of the rs10757274 polymorphism with severity of coronary artery disease. Methods: This was an association study, including 487 unrelated Venezuelan individuals, grouped in 354 patients with AMI and 133 controls. The rs1333049 and rs10757274 polymorphisms were determined using the polymerase chain reaction (PCR) technique with sequence-specific primers. The analysis of association was determined using the SNPStats tool. The continuous variable description and the correlations were performed using the SPSS statistical software. Significance was established at p<0.05. Results: A positive correlation was observed between the rs1333049 polymorphism and the presence of hypertension ( r: 0.145, p: 0.006), and between hypertension and heart infarction ( r: 0.318, p: <0.0001). A positive correlation was found between the rs10757274 polymorphism and the number of coronary vessels that presented obstructive lesions in patients aged ≤ 55 years ( r: 0.276, p: 0.0078). Conclusion: The rs1333049 polymorphism at the 9p21 locus is correlated with hypertension in Venezuelan patients, while the rs10757274 polymorphism is associated with the progression of coronary atherosclerosis, suggested by the correlation with the number of coronary vessels that presented significant obstructive lesions.

Mid- to Late-Life Time-Averaged Cumulative Blood Pressure and Late-Life Retinal Microvasculature: The ARIC Study.

Background The associations of time-averaged cumulative blood pressure (BP) from midlife to late life with microvasculature expressed as retinal vessel diameters is not well studied. The aim of this study was to evaluate the association of cumulative systolic BP and diastolic BP (DBP) with retinal vessel calibers, focusing on race differences. Methods and Results The analysis included 1818 adults from the ARIC (Atherosclerosis Risk in Communities) study attending the fifth visit (2011-2013; age 77±5 years, 17.1% Black participants). Time-averaged cumulative BPs were calculated as the sum of averaged BPs from adjacent consecutive visits (visits 1-5) indexed to total observation time (24±1 years). Summarized estimates for central retinal arteriolar equivalent and central retinal venular equivalent at the fifth visit represent average retinal vessel diameters. The arteriole:venule ratio was calculated. We tested for effect modification by race. Results from multiple linear regression models suggested that higher time-averaged cumulative DBP (ß [95% CI] per 1-SD increase: -1.78 [-2.53, -1.02], P<0.001 and -0.005 [-0.009, -0.002], P=0.004, respectively) but not systolic BP (-0.52 [-1.30, 0.26], P=0.189 and 0.001 [-0.002, 0.005], P=0.485, respectively) was associated with smaller central retinal arteriolar equivalent and arteriole:venule ratio. The association between time-averaged cumulative DBP and arteriole:venule ratio was strongest in White participants (interaction P=0.007). The association of cumulative systolic BP and DBP with central retinal venular equivalent was strongest in Black participants (interaction P=0.015 and 0.011, respectively). Conclusions Exposure to higher BP levels, particularly DBP, from midlife to late life is associated with narrower retinal vessel diameters in late life. Furthermore, race moderated the association of cumulative BP exposure with retinal microvasculature.

Association of ALDH2 rs671 and MTHFR rs1801133 polymorphisms with hypertension among Hakka people in Southern China.

BACKGROUND: Genetic factors play an important role in susceptibility to hypertension. Herein, the association between acetaldehyde dehydrogenase 2 (ALDH2) and methylenetetrahydrofolate reductase (MTHFR) gene polymorphisms and hypertension was analyzed among Hakka population in southern China. METHODS: A total of 3057 hypertensive patients and 2215 controls were enrolled. The ALDH2 rs671 and MTHFR rs1801133 genotyping were analyzed using gene chip. Relevant information and medical records of these subjects were collected. RESULTS: Hypertensive patients with ALDH2 rs671 G/A heterozygous had lower systolic blood pressure (SBP) than other genotypes (P < 0.001), while hypertensive patients with A allele had lower diastolic blood pressure (DBP) than patients with G allele (P < 0.001). The level of plasma homocysteine (Hcy) in patients with MTHFR CC, CT and TT genotypes showed an increasing trend (P < 0.001). The ALDH2 G/A genotype in the co-dominant model (adjusted OR 1.251, 95% CI 1.024-1.528, P = 0.028) and ALDH2 A/A genotype in the recessive model (adjusted OR 1.221, 95% CI 1.008-1.478, P = 0.041) were significant risk factors for the presence of hypertension. The MTHFR C/T genotype in the co-dominant model (adjusted OR 1.307, 95% CI 1.039-1.643, P = 0.022) and MTHFR C/T and T/T genotypes in the dominant model (adjusted OR 1.281, 95% CI 1.146-1.430, P < 0.001) were significant risk factors for the presence of hypertension. Further, logistic regression analysis showed that age, smoking, alcohol consumption, hyperhomocysteinemia, and high level of serum TG, Apo-A1, Apo-B were significant risks for hypertension. CONCLUSIONS: In summary, ALDH2 rs671 G/A, A/A genotypes and MTHFR rs1801133 C/T, T/T genotypes may be risk factors for hypertension in this Chinese Hakka population.

OCTA Derived Vessel Skeleton Density Versus Flux and Their Associations With Systemic Determinants of Health.

Purpose: To examine the associations of optical coherence tomography angiography (OCTA)-derived retinal capillary flux with systemic determinants of health. Methods: This is a cross-sectional study of subjects recruited from the African American Eye Disease Study. A commercially available swept-source (SS)-OCTA device was used to image the central 3 × 3 mm macular region. Retinal capillary perfusion was assessed using vessel skeleton density (VSD) and flux. Flux approximates the number of red blood cells moving through vessel segments and is a novel metric, whereas VSD is a previously validated measure commonly used to quantify capillary density. The associations of OCTA derived measures with systemic determinants of health were evaluated using multivariate generalized linear mixed-effects models. Results: A total of 154 eyes from 83 participants were enrolled. Mean VSD and flux were 0.148 ± 0.009 and 0.156 ± 0.016, respectively. In a model containing age, systolic blood pressure, diabetes status, hematocrit, and presence of retinopathy as covariates, there was a negative correlation between VSD and age (P < 0.001) and retinopathy (P = 0.02), but not with hematocrit (P = 0.85) or other factors. There was a positive correlation between flux and hematocrit (P = 0.02), as well as a negative correlation for flux with age (P < 0.001), systolic blood pressure (P = 0.04), and diabetes status (P = 0.02). A 1% decrease in hematocrit was associated with the same magnitude change in flux as ∼1.24 years of aging. Signal strength was associated with flux (P < 0.001), but not VSD (P = 0.51). Conclusions: SS-OCTA derived flux provides additional information about retinal perfusion distinct from that obtained with skeleton density-based measures. Flux is appropriate for detecting subclinical changes in perfusion in the absence of clinical retinopathy.

Choice of home blood pressure monitoring device: the role of device characteristics among Alaska Native and American Indian peoples.

BACKGROUND: Home blood pressure monitoring (HBPM) is an effective tool in treatment and long-term management of hypertension. HBPM incorporates more data points to help patients and providers with diagnosis and management. The characteristics of HBPM devices matter to patients, but the relative importance of the characteristics in choosing a device remains unclear. METHODS: We used data from a randomized cross-over pilot study with 100 Alaska Native and American Indian (ANAI) people with hypertension to assess the choice of a wrist or arm HBPM device. We use a random utility framework to evaluate the relationship between stated likely use, perceived accuracy, ease of use, comfort, and participant characteristics with choice of device. Additional analyses examined willingness to change to a more accurate device. RESULTS: Participants ranked the wrist device higher compared to the arm on a 5-point Likert scale for likely use, ease of use, and comfort (0.3, 0.5, 0.8 percentage points, respectively). Most participants (66%) choose the wrist device. Likely use (wrist and arm devices) was related to the probability of choosing the wrist (0.7 and - 1.4 percentage points, respectively). Independent of characteristics, 75% of participants would be willing to use the more accurate device. Ease of use (wrist device) and comfort (arm device) were associated with the probability of changing to a more accurate device (- 1.1 and 0.5 percentage points, respectively). CONCLUSION: Usability, including comfort, ease, and likely use, appeared to discount the relative importance of perceived accuracy in the device choice. Our results contribute evidence that ANAI populations value accurate HBPM, but that the devices should also be easy to use and comfortable to facilitate long-term management.
