258例高血压患者糖代谢状况调查分析

目的调查原发性高血压患者伴有糖代谢异常的流行病学情况,为全面干预危险因素提供科学依据。方法对在我院门诊或所辖社区卫生服务站点就诊不知晓自患糖尿病的258例高血压患者进行糖代谢状况的问卷调查静脉血糖测定。结果258例患者行空腹血糖(FPG)和口服葡萄糖耐量试验(OGTT)后2小时血糖测定,其中79人(30.6%)达到了糖尿病诊断标准,糖调节受损期(IGR)者93人(36.0%),糖代谢异常者共为172人(66.7%)。原发性高血压合并糖尿病患者与无合并糖尿病患者相比,体重指数、腰围呈上升趋势,空腹血糖受损组(IFG)和正常葡萄糖耐量组(NGT)间比较无差异(P>0.05),葡萄糖耐量减低组(IGT)或糖尿病组,有显著性差异(P<0.05);血脂异常也越加明显,TG、TC、LDL呈上升趋势,HDL则下降;IGT组HOMA-IR明显升高(P<0.01),与糖尿病组比较无差异;IGT组HOMA-B细胞功能升高,与其他组间比较无差异;糖尿病和IGT组ISI下降。结论原发性高血压患者合并糖耐量异常的比例非常高,而日常诊断率却很低。对于合并代谢综合征的高血压患者,更应关注糖代谢情况,并积极进行OGTT,以早期发现和治疗糖代谢紊乱。     

糖耐量低减和空腹血糖受损:定义及干预的现状

由国际糖尿病联盟 (IDF)召集的本次研讨会是为了考察有关糖耐量低减 (IGT)和空腹血糖受损 (IFG)相关的糖尿病和心血管疾病 (CVD)风险的最新文献 ,力图回答三个问题 :(1 )目前的IGT和IFG的定义是否合适 ;(2 )IFG和IGT是危险因子 (riskfactor)、危险标志 (riskmarker)还是疾病 (disease) ;(3)对 :IFG和IGT人群应该采取怎样的干预措施 (如果有的话 ) ?①引起空腹血糖 (FPG)和口服葡萄糖耐量试验(OGTT) 2h血糖 (2hPG)升高的因素并不相同 ,肝脏葡萄糖输出增加和早期胰岛素释放缺陷是前者的特点 ,而外周胰岛素抵抗是后者的显著特征。因此 ,IFG和IGT之间的一致性是有限的。迄今所有的患病率调查发现 ,只有不到一半的IFG人群有IGT ,更少的IGT人群 (2 0 %～ 30 % )有IFG。②大多数的人群研究表明 ,IGT的患病率远高于IFG ,二者的临床表现和性别分布也有差异。IFG在男性更为常见 ,IGT在女性稍微增多。IFG的患病率倾向在中年达到高峰 ,而IGT的患病率逐渐增加直到老龄。③IFG和IGT都与发生糖尿病的风险显著增加有关 ,而最大的风险在于同时具有IFG和IGT的人群。由于在多数人群IGT比IFG更常见 ,所以对于筛查糖尿病高危人群 ,IGT的敏感性较高 (特异性稍差 )。在多数人群 ,60 %的糖尿病人大约 5年前已有IGT或IFG ,另外 40

中老年人群糖代谢异常的临床特点分析

目的:探讨中老年人群糖代谢异常的分布情况及其临床特点。方法:测定951例年龄≥45岁人群的身高、体重、腰围、臀围,计算体重指数(BMI)、腰臀比(WHR);口服75g葡萄糖耐量试验确定其糖代谢状态,测定血脂、空腹及餐后2h血浆血糖和血清胰岛素水平,用稳态模型评估法(HOMA)计算胰岛素抵抗(IR)指数(HOMA-IR)、胰岛细胞功能指数(HOMA-β),进行组间比较。结果:①糖耐量正常者(NGT)占53.00%,单纯糖耐量异常(IGT)占25.34%;空腹血糖受损(IFG)占5.15%;IFG合并IGT占3.79%;糖尿病(DM)占12.72%;②IGT、IFG+IGT、DM患者的年龄、血压、脉压、BMI显著高于NGT和IFG者;WHR值按NGT、IFG→IGT→IFG+IGT、DM的顺序依次增高(P<0.05);IGT、IFG+IGT、DM者的三酰甘油(TG)水平高于NGT者(P<0.05),其中隐性糖尿病(LDM)和显性糖尿病(ODM)患者的TG水平又显著高于IFG者(P<0.05);③IR的程度按NGT、IGT→IFG→LDM→IFG+IGT→ODM的顺序依次升高;除IGT外,其他糖代谢异常的IR程度均显著高于NGT(P<0.05);HOMA-β按IGT、NGT→LDM→IFG+IGT→IFG→ODM的顺序依次降低;各组中以ODM的IR最高,基础胰岛素分泌功能最差。结论:中老年人群的糖代谢异常的患病率高,应重视对餐后血糖的检测,合并有中心性肥胖、高血压等危险因素者建议做口服葡萄糖耐量试验以明确诊断。中老年人群中糖代谢异常者普遍存在IR及胰岛β细胞分泌功能不足。     

Determinants of hypertension among adults in Bangladesh as per the Joint National Committee 7 and 2017 American College of Cardiology/American Hypertension Association hypertension guidelines

We investigated determinants of hypertension in Bangladesh using both Joint National Committee 7 (JNC7) and 2017 American College of Cardiology/American Hypertension Association (2017 ACC/AHA) guidelines. After reporting background characteristics, odds ratios (ORs) were obtained by multilevel logistic regression. Among 7839 respondents aged ≥35 years, 25.7% (n = 2016) and 48.0% (n = 3767) respondents had hypertension as per the JNC7 and 2017 ACC/AHA guidelines, respectively. The following factors were significant according to the 2017 ACC/AHA guideline: ≥65 years (adjusted OR [AOR]: 2.4, 95% confidence interval [CI]: 2.2–3.0), 55–64 years (AOR: 1.6, 95% CI: 1.4–1.9), and 45–54 years (AOR: 1.4, 95% CI: 1.3–1.6) age groups, females (AOR: 2.0, 95% CI: 1.7–2.2), overweight/obesity (AOR: 2.4, 95% CI: 2.0–2.8), diabetes (AOR: 1.4, 95% CI: 1.2–1.6), secondary (AOR: 1.2, 95% CI: 1.1–1.4), or college education level (AOR: 1.8, 95% CI: 1.4–2.3), middle (AOR: 1.3, 95% CI: 1.1–1.6), richer (AOR: 1.5, 95% CI: 1.2–1.8) or richest (AOR: 2.0, 95% CI: 1.6–2.4) wealth quintiles, residence in Khulna (AOR: 1.5, 95% CI: 1.2–1.9), and Rangpur (AOR: 1.7, 95% CI: 1.3–2.2) divisions. All factors were significant as per the JNC7 guideline too. Both guidelines found similar determinants. Prevention and control programs should prioritize increasing awareness among people with higher likelihood of hypertension.     

The contribution of the systolic and diastolic components for the diagnosis of arterial hypertension under the 2017 ACC/AHA Guideline and metabolic heterogeneity among individuals with Stage 1 hypertension

Little is known about the impact of the 2017 ACC/AHA hypertension guideline on the distribution pattern of hypertension modalities (isolated systolic hypertension [ISH], isolated diastolic hypertension [IDH], and systolic‐diastolic hypertension [SDH]). This cross‐sectional study had the following objectives: to compare the prevalence of hypertension, ISH, IDH, and SDH, according to the definitions of the JNC 7 or the 2017 guideline; to determine the relative contribution of the systolic and the diastolic components for the diagnosis of hypertension; and to compare the metabolic profile of ISH, IDH, or SDH among new hypertensive individuals by the 2017 guideline. The authors retrospectively evaluated 33 594 patients (42 ± 10 years, 67% male) who underwent a routine health evaluation. Hypertensive patients not using antihypertensive medication were classified into ISH, IDH, or SDH using guideline‐defined thresholds. The prevalence of hypertension increased from 21.1% by the JNC 7 definition to 54.7% using the 2017 criteria (2.6‐fold increase). More profound increases were seen in the prevalence of IDH (8.7‐fold) and SDH (3.3‐fold), whereas the prevalence of ISH reduced from 1.1% (JNC 7) to 0.5% (2017 definition). Among patients with Stage 1 hypertension by the 2017 document, 85% had IDH and fewer metabolic abnormalities compared to those with SDH or ISH. The authors concluded that the 2017 guideline inflates the role of the diastolic component and diminishes the contribution of the systolic component for the diagnosis of hypertension. Individuals with Stage 1 hypertension by the 2017 guideline are metabolically heterogeneous and may have different long‐term prognoses.     

Secular trends of hypertension prevalence based on 2017 ACC/AHA and 2018 Chinese hypertension guidelines: Results from CHNS data (1991‐2015)

This study aimed to assess the impact of the 2017 American College of Cardiology and American Heart Association (ACC/AHA) guideline and the 2018 Chinese hypertension guidelines on the different secular trends for hypertension prevalence. A total of 82 665 eligible individuals aged ≥20 years were selected from nine cross‐sectional study periods (1991‐2015) from the China Health and Nutrition Survey (CHNS). Over the 24‐year period, the long‐term trend for the prevalence of the 2017 ACC/AHA‐defined age‐adjusted hypertension showed an increase from 32.2% (95% confidence interval (CI): 31.0%‐33.3%) in 1991 to 60.0% (95% CI: 58.6%‐61.3%) in 2015 (P_trend < 0.001). According to the 2018 Chinese guideline for hypertension, the weighted hypertension prevalence increased from 10.0% (95% CI: 9.4%‐10.5%) in 1991 to 28.7% (95% CI: 27.9%‐29.6%) in 2015 (P_trend < 0.001). However, slopes of increasing prevalence of hypertension were significantly greater according to the 2017 ACC/AHA guideline than that based on Joint National Committee (JNC 7) report (β = 1.00% vs β = 0.67% per year, respectively, P = 0.041). Based on the 2017 ACC/AHA definition, the prevalence of stage 1 hypertension and elevated blood pressure significantly increase from 22.3% and 6.9% in 1991 to 31.2% and 10.1% in 2015 (all P < 0.05), respectively. The secular trend for the prevalence of hypertension according to the 2017 ACC/AHA guideline showed a greater rate of increase compared with the prevalence based on the 2018 Chinese hypertension guidelines. Public health initiatives should focus on the current status of hypertension in China because of the possible high prevalence of hypertension and concomitant vascular risks.     

Blood pressure goals: A moving target

Clinical guidelines on hypertension have evolved over the past several decades. Each recommends varying blood pressure (BP) cut-offs which define hypertension, determine the thresholds to initiate pharmacotherapy, and guide treatment targets. In addition, different techniques of measuring BP in clinical trials may further contribute to the discrepancies in the achieved BP targets. Physicians find it difficult to navigate through different recommendations for hypertension management based on studies among different age groups and patients with a variety of co-morbidities and target organ involvement. In 2003, JNC 7 recommended a BP goal of < 140/90 mmHg in the general population and < 130/80 mmHg in those with diabetes mellitus or renal disease. JNC 8 re-set the BP target at < 140/90 mmHg for all adults under the age of 60 regardless of co-morbidities, and an even higher target of < 150/90 mmHg for those 60 years or older without diabetes or chronic kidney disease. The more recent results of the Systolic BP Intervention Trial (SPRINT) have a significant influence on the 2017 American College of Cardiology (ACC) and American Heart Association (AHA) guideline which redefines hypertension as BP ≥ 130/80 mmHg. It emphasizes individualized cardiovascular risk assessment and recommends a more aggressive BP target of < 130/80 mmHg and a treatment threshold based on the age, co-morbidities, and cardiovascular risk. The 2017 ACC/AHA guideline also advocates proper BP measurement and provides the estimates of corresponding BP values for clinic, home, and ambulatory BP monitoring measurements. A higher prevalence of hypertension is expected based on the ACC/AHA 2017 guideline. Its implementation may potentially lead to better BP control through enhanced awareness, improved adherence, and more timely initiation and intensification of pharmacologic therapy. Although there is no one-size-fits-all BP target, the ACC/AHA 2017 guideline is simple, inclusive and practical. Nonetheless, more studies are warranted to help further individualize BP goals for elderly patients and those with certain co-morbidities or multiple cardiovascular risk factors.     

Potential U.S. Population Impact of the 2017 ACC/AHA High Blood Pressure Guideline

Background

The 2017 American College of Cardiology/American Heart Association (ACC/AHA) Guideline for the Prevention, Detection, Evaluation and Management of High Blood Pressure in Adults provides recommendations for the definition of hypertension, systolic and diastolic blood pressure (BP) thresholds for initiation of antihypertensive medication, and BP target goals.

Control of blood pressure levels in patients with premature coronary artery disease: Results from the Genetics of Atherosclerotic Disease study

High blood pressure (BP) is the major cardiovascular‐risk factor for coronary artery disease (CAD), principally in young patients who have an important and increasing socioeconomic burden. Despite the Seventh Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure (JNC‐7), recommended BP target <140/90 mm Hg for patients with stable CAD, in 2017 the American College of Cardiology and the American Heart Association (ACC/AHA) updated BP target to <130/80 mm Hg. We aimed to analyze the prevalence of BP control in patients with premature CAD using both criteria. In addition, antihypertensive therapy, lifestyle, clinical, and sociodemographic characteristics of the patients were evaluated in order to identify factors associated with the achievement of BP targets. The present study included 1206 patients with CAD diagnosed before 55 and 65 years old in men and women, respectively. Sociodemographic, clinical, and biochemical data were collected. The results indicate that 85.6% and 77.5% of subjects with premature CAD achieved JNC‐7 non‐strict and ACC/AHA strict BP target, respectively. Consistently, number of antihypertensive drugs and hypertension duration >10 years were inversely associated with BP targets, whereas total physical activity and smoking were directly associated with BP targets, regardless of BP criteria. Considering that age, gender, and hypertension duration are non‐modifiable cardiovascular‐risk factors, our results highlight the need for more effective strategies focused on increase physical activity and smoking cessation in young patients with CAD. These healthier lifestyles changes should favor the BP target achievement and reduce the socioeconomic and clinical burden of premature CAD.     

Updated hypertension prevalence,awareness, and control rates based on the 2017ACC/AHA high blood pressure guideline

In 2017, the American College of Cardiology/American Heart Association (ACC/AHA) updated the Guideline of Prevention, Detection, Evaluation and Management and Management of High Blood Pressure (HBP) in Adults. The purpose of the current study was to evaluate the potential impact of the 2017ACC/AHA HBP guideline on hypertension prevalence, awareness, and control rates. The data were collected from Physical Examination Center of the Second Hospital of Hebei Medical University from January 2012 to December 2017 (N = 66 977), including demographic information and risk factors of hypertension. The hypertension prevalence, awareness, and control rates of people were evaluated according to the new guideline. Additionally, the factors related to hypertension prevalence were also assessed. According to previous HBP guideline, hypertension prevalence, awareness, and control rate were 30.54%, 44.33%, and 13.04%, respectively. However, when the 2017 ACC/AHA HBP guideline was introduced, the population with hypertension increased from 20 453 to 34 460, the hypertension prevalence rate increased from 30.54% to 51.45%, the awareness rate decreased from 44.33% to 26.31%, and the control rate declined from 13.04% to 2.72%. The most newly diagnosed hypertension patients were from the low‐risk population with young age and without the above histories. The 2017ACC/AHA HBP guideline indicated that high hypertension prevalence rate still existed with a substantial increase, while the awareness and control rates were relatively lowered.     

Prevalence of hypertension in a Mexican population according to the Sixth Report of the Joint National Committee on Prevention, Detection, Evaluation and Treatment of High Blood Pressure.

BACKGROUND: Hypertension in Mexico represents a challenging public health problem. The National Survey on Chronic Diseases published in 1993 reported that hypertension affects more than 10 million Mexicans. No information has been published regarding the prevalence of hypertension in Mexico using the new diagnostic criteria established by the Sixth Report of the Joint National Committee on Prevention, Detection, Evaluation and Treatment of High Blood Pressure (JNC VI). METHODS: The Mexico City Diabetes Study is a prospective study designed to estimate the prevalence and incidence of cardiovascular risk factors in a low-income area. The survey included 941 men and 1341 non-pregnant women aged 35-64 years. Blood pressure measurements were performed using a random zero sphygmomanometer. The diagnostic criteria for hypertension were those recommended by the JNC VI. RESULTS: The crude prevalence of hypertension was 17.2% and 18.1% in men and women, respectively. We found significant associations between hypertension and obesity, body fat distribution, very-low-density lipoprotein cholesterol, fasting and 2-h post-glucose in both sexes, and between hypertension and total cholesterol, low-density lipoprotein cholesterol and triglycerides levels in women. In 40% of hypertensive men and 23% of women, hypertension was undiagnosed and untreated. Of the previously diagnosed hypertensive individuals, 38% of men and 30% of women reported not taking antihypertensive medicine. The prevalence++ of associated risk factors in this population is 12.3% for tobacco consumption, 22.4% for diabetes, 49.8% for hypertriglyceridemia and 40.9% for hypercholesterolemia. CONCLUSIONS: Hypertension occurs in 18% of this population. There is a high prevalence of undiagnosed and untreated cases. Associated cardiovascular risk factors are highly prevalent.     

The prevalence of hypertension and diabetes defined by fasting and 2-h plasma glucose criteria in urban Nepal.

AIMS: To determine the prevalence of diabetes, impaired fasting glucose and impaired glucose tolerance (IGT) in people aged >/= 40 years in urban communities of Nepal, comparing the fasting and 2-h plasma glucose (PG) criteria for diagnosis of diabetes and to relate the prevalence to age, gender and hypertension. METHODS: Field surveys of fasting and 2-h PG and blood pressure (BP) were done by cluster sampling in seven urban populations of Nepal. Of 1180 eligible individuals invited, 1012 (85.7%) aged >/= 40 years participated. RESULT: The age and sex standardized prevalence of diabetes (known and newly diagnosed), IGT and impaired fasting glycaemia (IFG) were 19.0%, 10.6% and 9.9%, respectively. Of the total population, 30.5% (37.8% of men and 25.3% of women) had some abnormality of glucose tolerance. Of all diabetic individuals, 54.4% (53.8% of men and 55.1% of women) were undiagnosed. The prevalence of diabetes increased with age until the age of 75 years. The prevalence of diabetes was higher in men than in women (P < 0.001). The sensitivity of the fasting plasma glucose (FPG) criterion compared with either FPG or 2-h PG or both criteria for the diagnosis of diabetes was 70.5%[95% confidence interval (CI) 60.7, 78.8] and the corresponding sensitivity of 2-h PG criterion was 79% (95% CI 69.8, 86.1). The age- and sex-standardized prevalence of hypertension (BP >/= 140/90 mmHg) was 22.7%. Hypertension was less common in subjects with normal plasma glucose than in those with diabetes (18.8% vs. 36.7%). Similarly, of all subjects with hypertension, 29.1% had diabetes (known or newly diagnosed) and 43.0% had glucose intolerance of some form. CONCLUSIONS: Our study shows that diabetes and hypertension are common and related problems in people aged >/= 40 years in urban Nepal. The overall sensitivity of the 2-h PG criteria was greater than that of the FPG criteria for diagnosing diabetes, except in subjects aged >/= 60 years.     

Baseline Blood Pressure,the 2017 ACC/AHA High Blood Pressure Guidelines,and Long-Term Cardiovascular Risk in SPRINT

Background

The 2017 American College of Cardiology (ACC)/American Heart Association (AHA) guidelines include lower thresholds to define hypertension than previous guidelines. Little is known about the impact of these guideline changes in patients with or at high risk for cardiovascular disease.
