Abstract

BACKGROUND:Cardiovascular disease related mortality is the leading cause of death in the United States, with hypertension being the most prevalent and potent risk factor. For decades hypertension has disproportionately affected African Americans, who also have a higher burden of associated comorbidities including diabetes and heart failure. METHODS:Current literature including guideline reports and newer studies on hypertension in African Americans in PubMed were reviewed. We also reviewed newer publications on the relationship between COVID-19 and cardiovascular disease. FINDINGS:While APOL1 has been theorized in the epidemiology of hypertension, the increased prevalence and associated risks are primarily due to environmental and lifestyle factors. These factors include poor diet, adverse lifestyle, and social determinants. Hypertension control can be achieved by lifestyle modifications such as low sodium diet, weight loss, and adequate physical activity. When lifestyle modifications alone do not adequately control hypertension, a common occurrence among African Americans who suffer with greater prevalence of resistant hypertension, pharmacological intervention is indicated. The efficacy of renal denervation, and the use of sodium-glucose cotransporter 2 and aminopeptidase A inhibitors, have been studied for treatment of resistant hypertension. Furthermore, the recent COVID-19 crisis has been particularly devastating among African Americans who demonstrate increased incidence and poorer health outcomes related to the disease. CONCLUSION:The disparities in outcomes, which are largely attributable to a greater prevalence of comorbidities such as hypertension and obesity, in addition to adverse environmental and socioeconomic factors, highlight the necessity of specialized clinical approaches and programs for African Americans to address longstanding barriers to equitable care.

摘要

背景: 在美国,心血管疾病相关的死亡率是死亡的主要原因,高血压是最普遍和最有效的危险因素。几十年来,高血压不成比例地影响了非裔美国人,他们也有更高的相关合并症负担,包括糖尿病和心力衰竭。 方法: 对PubMed中关于非裔美国人高血压的现有文献,包括指南报告和较新的研究进行了综述。我们还回顾了关于新型冠状病毒肺炎与心血管疾病之间关系的新出版物。 结果: 虽然APOL1在高血压流行病学中被理论化,但患病率和相关风险的增加主要是由于环境和生活方式因素。这些因素包括不良饮食、不良生活方式和社会决定因素。高血压的控制可以通过生活方式的改变,如低钠饮食,体重减轻和足够的身体活动来实现。当单独的生活方式改变不能充分控制高血压 (在患有较高患病率的顽固性高血压的非裔美国人中常见) 时,需要药物干预。已经研究了肾脏去神经支配的功效以及钠-葡萄糖协同转运蛋白2和氨肽酶A抑制剂用于治疗顽固性高血压。此外,最近的新型冠状病毒肺炎危机在非裔美国人中尤其具有破坏性,他们表现出与该疾病相关的发病率增加和较差的健康结果。 结论: 除了不利的环境和社会经济因素之外,结局的差异主要归因于高血压和肥胖等合并症的患病率较高,这突出了针对非裔美国人的专门临床方法和项目的必要性,以解决公平护理的长期障碍。

METHODS::Aim: We explored the role of histone modification in the association of depression-hypertension by comparing norepinephrine transporter (NET) gene levels in different depression-hypertensive patients. Then, we analyzed the expression of NET correlation with inflammatory cytokines to provide a new direction for detecting the association mechanism between depression and hypertension.Methods: NE expression levels in serum of diverse groups were detected by enzyme-linked immunosorbent assay. Then histone acetyltransferase (HAT), histone deacetylase (HDAC), H3K27ac, NET, TNF-α, and interleukin-6 (IL-6) were detected by western blot in nine female subjects in different depression and hypertension groups, and Chromatin immunoprecipitation-polymerase chain reaction (Chip-PCR) were used to confirm the degree of acetylation affecting on the transcription level of NET gene. Meanwhile, correlation between NET with TNF/IL-6 was analyzed by SPSS19.0 software program. Finally, Quantitative real-time polymerase chain reaction (qPCR) and western blot were used to detect TNF-α and IL-6 expression levels after NET overexpression or interference treatment in human umbilical vein endothelial cells and Neuro-2a cells.Results: The expression of HAT and H3K27ac had lower levels in D-H and nonD-H group than nonD-nonH group. The results showed that higher acetylation could promote expression of NET genes. Meanwhile, the expression of NET had a significant negative correlation with IL-6 (R = -0.933, p < 0.01) and tumor necrosis factor (TNF) (R = -0.817, p < 0.01) in subjects. In addition, the results confirmed that TNF-α and IL-6 mRNA and protein partial expressions could be inhibited by NET in both HUVECs and Neuronal cells (p < 0.01).Conclusion: In conclusion, differential expression of NET gene might function as an important factor in interaction between depression and hypertension by partially targeting TNF-α and IL-6.

METHODS::The Middle East and North Africa (MENA) region has a high burden of morbidity and mortality due to premature (≤55 years in men; ≤65 years in women) myocardial infarction (MI) and acute coronary syndrome (ACS). Despite this, the prevalence of risk factors in patients presenting with premature MI or ACS is incompletely described. We compared lifestyle, clinical risk factors, and biomarkers associated with premature MI/ACS in the MENA region with selected non-MENA high-income countries. We identified English-language, peer-reviewed publications through PubMed (up to March 2018). We used the World Bank classification system to categorize countries. Patients with premature MI/ACS in the MENA region had a higher prevalence of smoking than older patients with MI/ACS but a lower prevalence of diabetes, hypertension, and dyslipidemia. Men with premature MI/ACS had a higher prevalence of smoking than women but a lower prevalence of diabetes and hypertension. The MENA region had sparse data on lifestyle, diet, psychological stress, and physical activity. To address these knowledge gaps, we initiated the ongoing Gulf Population Risks and Epidemiology of Vascular Events and Treatment (Gulf PREVENT) case-control study to improve primary and secondary prevention of premature MI in the United Arab Emirates, a high-income country in the MENA region.

METHODS:OBJECTIVE:The aim of our study was to determine if a genetic background of high blood pressure is a survival factor in preterm infants. DESIGN:Prospective cohort study. SETTING:Patients were enrolled in 53 neonatal intensive care units. PATIENTS:Preterm infants with a birth weight below 1500 g. EXPOSURES:Genetic score blood pressure estimates were calculated based on adult data. We compared infants with high genetic blood pressure estimates (>75th percentile of the genetic score) to infants with low genetic blood pressure estimates (<25th percentile of the genetic score). MAIN OUTCOME MEASURES:Lowest blood pressure on the first day of life and mortality. RESULTS:5580 preterm infants with a mean gestational age of 28.1±2.2 weeks and a mean birth weight of 1022±299 g were genotyped and analysed. Infants with low genetic blood pressure estimates had significantly lower blood pressure if compared with infants with high genetic blood pressure estimates (27.3±6.2vs 27.9±6.4, p=0.009, t-test). Other risk factors for low blood pressure included low gestational age (-1.26 mm Hg/week) and mechanical ventilation (-2.24 mm Hg, p<0.001 for both variables, linear regression analysis). Mortality was significantly reduced in infants with high genetic blood pressure estimates (28-day mortality: 21/1395, 1.5% vs 44/1395, 3.2%, p=0.005, Fisher's exact test). This survival advantage was independent of treatment with catecholamines. CONCLUSIONS:Our study provides first evidence that a genetic background of high blood pressure may be beneficial with regard to survival of preterm infants.

高血压方向

高血压(hypertension)是指以体循环动脉血压(收缩压和/或舒张压)增高为主要特征(收缩压≥140毫米汞柱,舒张压≥90毫米汞柱),可伴有心、脑、肾等器官的功能或器质性损害的临床综合征。高血压是最常见的慢性病,也是心脑血管病最主要的危险因素。临床上高血压可分为两类:原发性高血压和继发性高血压。
