Agreement analysis of stroke volume and cardiac output measurement between a oscillometric device and transthoracic echocardiogram in normotensive individuals: a preliminary report

Abstract Introduction The evaluation of stroke volume (SV) is useful in research and patient care. To accomplish this, an ideal device should be noninvasive, continuous, reliable, and reproducible. The Mobil-O-Graph (MOG) is a noninvasive oscillometric matrix validated for measuring aortic and peripheral blood pressure, which through conversion algorithms can estimate hemodynamic parameters. Objectives To compare the MOG measurement of stroke volume, cardiac output, and cardiac index with the transthoracic echocardiogram (TTE). Methods Healthy volunteers aged 18 years or older were included. Two-dimensional TTEs were performed by a single operator. Subsequently, the measurement of noninvasive hemodynamics with MOG was performed with the operator blind to the results of the echocardiogram. Correlation analyses between stroke volume, cardiac output, and cardiac index parameters were performed. The degree of agreement between the methods was verified using the Bland-Altman method. Results A total of 38 volunteers were enrolled with a mean age of 27.6 ± 3.8 years; 21 (55%) were male The SV by TTE was 76.8 ± 19.5 mL and 75.7 ± 19.3 mL by MOG, Rho = 0.726, p< 0.0001. The CO by TTE was 5.04 ± 0.8 mL.min-1 and 5.1 ± 0.8 mL.min-1 by MOG Rho = 0.510, p= 0.001. Bland-Altman plots showed a good concordance between the two techniques. Conclusions Our study shows that the measurement of SV and CO by noninvasive hemodynamics with the MOG device offers a good concordance with the TTE with very few values beyond the confidence limits.

In individual care, the use of a single pill and measures to avoid forgetting of medication taken were highlighted. Conclusion: the study was able to characterize the employees and their adherence to anti-hypertensive treatment, facilitating and hindering factors, and to point out institutional intervention strategies to improve adherence and quality of life (AU).

Implementation of maternal guidelines for gravid teenagers with hypertensive disorders in KwaZulu-Natal

Background: The worldwide phenomenon of teenage pregnancy among 13­9-year-olds is complicated by obstetric conditions. Among the top three causes of maternal mortality, hypertension is the third in South Africa. Quality maternal care is assured by obstetric practitioners (OPs) implementing guidelines specific for management of hypertension in pregnancy. Objective: The objective of this study was to investigate implementation of maternal guidelines for hypertension in pregnancy among teenagers. Methods: As a retrospective quantitative research design was used, 173 maternal records of pregnant teenagers from 13 to 19 years were sampled from six district hospitals and Community Health Centres (CHCs) between 01 January 2017 and 31 December 2019 to undergo systematic random sampling. A pretested structured checklist was used to record data from sampled maternal records. Statistical Package for Social Sciences (SPSS) version 26 was used for data analysis, and results were presented using simple descriptive statistics. Results: Research results indicated that teenagers who suffered from hypertension intrapartum and postpartum did not receive maternal care according to the guidelines for maternity care in South Africa. Blood pressure was not measured of six (3.47%) intrapartum and five (2.9%) postpartum teenagers. Seventeen (9.8%) hypertensive postpartum teenagers received their antihypertensives. Conclusion: Public health institutions (PHIs) compromised provision of quality maternal care among teenagers, evidenced by incomplete intrapartum and postpartum assessment, diagnosis and management of hypertensive disorders in pregnancy (HDP).

Association between angiotensinogen M235T gene polymorphism and risk of hypertension: A case control study among Ethiopian patients

Background: Hypertension is a major public health problem in both developing and developed nations because it is highly prevalent and is associated with complications. Numerous enviromnental and genetic variables are linked to the occurrence of the disease. It may be influenced by the renin-angiotensin-aldosterone system, M'hich preserves bodily homeostasis. The angiotensinogen gene 11235T polymorphisms that has an effect on the activity of the renin-angiotensin-aldosterone system are related to the high hvpertension risk. The aim of this study was to find out the association between angiotensinogen Nf235T gene polymorphism and the risk of developing hypertenMon. Methods: A total of 306 samples - 153 patients Il'ith hvpertension and 153 age- and ser-matched healthy controls were selected using a simple random sampling technique. Clinical and biochemical variables were measured to assess the associated riskfactors. Blood samples from the patients and matched controls were used to isolate deoxyribonucleic acid. The AGT 11235T genotypes u:ere identified using polymerase chain reaction and analyzed by agarose gel electrophoresis. Logistic regression with a 95% confidence interval (CI) was employed to assess the risk correlations ofAGT gene M235Tpolymorphisms with hypertension. Results: Our analysis showed that the AGT-TT genotype (odds ratio [OR] = 3.11, 95% CL = 1.67­5.79, P< 0.001) and T allele (OR = 2.18, 95% CL = 1.56­3.04, P< 0.001) are considerably higher in hypertensive patients than in healthy controls. Our study also identified the clinical risk factors for hypertension, such as, total cholesterol, triglycerol, low density lipoprotein-cholesterol, and high density lipoprotein-cholesterol Inels, which were significantly higher in patients compared to controls (P< 0.001). Conclusion: The A GT M235T genes of the TT genotype and the T allele are associated with an increased risk of hypertension among the Ethiopian patients. A population-based epidemiological study is needed corroborate the association between AGT and HTN

Determinants of visit-to-visit systolic blood pressure variability among Ghanaians with hypertension and diabetes mellitus

Objective: To identify the determinants of systolic blood pressure variability (SBPV) among Ghanaians. Design: We undertook a secondary analysis of data collected in a prospective study Setting: The study involved patients with hypertension and or diabetes receiving care in five hospitals in Ghana Main outcome measures: We assessed determinants of SBPV among 2,785 Ghanaian patients. We calculated the standard deviation (SD) of systolic BP recordings of 3 to 10 visits per patient over 18 months as a measure of SBPV. A multivariate linear regression analysis was fitted to identify factors independently associated with risk visit-to-visit SBP standard deviation. Results: The mean SD of individual patient visit-to-visit SBP overall was 14.8±6.3 mm Hg. Those with hypertension and diabetes had the highest SD of 15.4 ±6.2 mm Hg followed by 15.2 ±6.5 mm Hg among those with hypertension only and then 12.0 ± 5.2 mm Hg among those with diabetes only, p<0.0001. Factors independently associated with SBPV with adjusted ß coefficients (95% CI) included age: 0.06 (0.03 ­ 0.08) for each year rise in age, eGFR -0.03 (-0.05 - -0.02) for each ml/min rise, low monthly income of <210 Ghana cedis 1.45 (0.43-2.46), and secondary level of education -1.10 (-1.69, -0.50). Antihypertensive classes were associated with SBPV, the strongest associations being hydralazine 2.35 (0.03 ­ 4.68) and Methyldopa 3.08 (2.39 ­ 3.77). Conclusion: Several socio-demographic and clinical factors are associated with SBPV. Future studies should assess the contribution of SBPV to CVD outcomes among indigenous Africans and identify actionable targets.

Sex-related differential prevalence of central obesity in diabetes mellitus: a multi-centred survey in North-Central Nigeria

Contrary to the old dictum that central obesity is more common among men than women, recent reports have shown a gradual reversal of this trend, as suggested by some studies. Objective: To compare the prevalence of central obesity among men and women with Diabetes mellitus in NorthCentral Nigeria. Methods: This multi-centred, cross-sectional study was conducted across 20 hospitals in Abuja, Nasarawa State, and Niger State, involving 1040 participants. Some obesity indices (body mass index, waist circumference and waist-toheight ratio) were measured. Results: The prevalence of central obesity (waist circumference criterion) was significantly higher in the females compared to male participants (89.6% vs 51.6%, χ2 = 1231.37, p<0.001), similar to the prevalence determined by waistheight ratio criterion (female vs male, 88.8% vs 71.5%, χ2 = 58.83, p<0.001). Following correction for age, duration of diabetes mellitus, blood pressure, blood glucose, and glycated haemoglobin using logistic regression, female gender remained a significant determinant of central obesity (OR = 2.76, 95% CI 1.81-3.83, p = 0.004). Conclusion: The prevalence of central obesity was higher among women than men in a cross-section of patients with diabetes mellitus in North-Central Nigeria

Inducible co-stimulatory molecules participate in mesenteric vascular endothelial-mesenchymal transition and sclerosis of mesenteric vessels in spontaneously hypertensive rats / 南方医科大学学报

OBJECTIVE@#To investigate the correlation of inducible co-stimulatory molecules (ICOS) with mesenteric vascular endothelial- mesenchymal transition (EndMT) and sclerosis in spontaneously hypertensive rats (SHR).@*METHODS@#Twenty 4-week-old WKY rats and 20 SHRs of the same strain were both randomly divided into 4 groups for observation at 4, 6, 10 and 30 weeks of age. ICOS expression frequency in rat spleen CD4+T cells was analyzed using flow cytometry, and the expressions of ICOS, VE-cad, α-SMA and Col3 mRNA in rat mesentery were detected by RT-PCR. The distributions of ICOS, IL-17A and TGF-β in rat mesentery were detected by immunohistochemistry. The levels of IL-17A and TGF-β in rat plasma were measured using ELISA. The morphological changes of rat mesenteric vessels were observed with Masson staining. Spearman or Pearson correlation analyses were used to evaluate the correlation between ICOS expression and the expressions of the markers of vascular EndMT and sclerosis.@*RESULTS@#Compared with the control WKY rats, the SHRs began to show significantly increased systolic blood pressure and ICOS expression frequency on CD4+T cells at 6 weeks of age (P < 0.05). In the SHRs, the mRNA and protein expressions of ICOS, α-SMA, Col3, IL-17A and TGF-β in the mesentery were significantly higher than those in control group (P < 0.05), while the mRNA and protein expressions of VE-cad started to reduce significantly at 10 weeks of age (P < 0.05). The plasma levels of IL-17A and TGF-β were significantly increased in SHRs since 6 weeks of age (P < 0.05) with progressive worsening of mesenteric vascular sclerosis (P < 0.05). ICOS mRNA and protein expression levels in the mesenteric tissues of SHRs began to show positive correlations with α-SMA and Col3 expression levels and the severity of vascular sclerosis at 6 weeks of age (P < 0.05) and a negative correlation with VE-cad expression level at 10 weeks (P < 0.05).@*CONCLUSION@#ICOS play an important pathogenic role in EndMT and sclerosis of mesenteric vessels in essential hypertension by mediating related immune responses.

Generation of Mlk3 KO mice by CRISPR/Cas9 and its effect on blood pressure / 生物工程学报

To explore the effect of Mlk3 (mixed lineage kinase 3) deficiency on blood pressure, Mlk3 gene knockout (Mlk3KO) mice were generated. Activities of sgRNAs targeted Mlk3 gene were evaluated by T7 endonuclease I (T7E1) assay. CRISPR/Cas9 mRNA and sgRNA were obtained by in vitro transcription, microinjected into zygote, followed by transferring into a foster mother. Genotyping and DNA sequencing confirmed the deletion of Mlk3 gene. Real- time PCR (RT-PCR), Western blotting or immunofluorescence analysis showed that Mlk3KO mice had an undetectable expression of Mlk3 mRNA or Mlk3 protein. Mlk3KO mice exhibited an elevated systolic blood pressure compared with wild-type mice as measured by tail-cuff system. Immunohistochemistry and Western blotting analysis showed that the phosphorylation of MLC (myosin light chain) was significantly increased in aorta isolated from Mlk3KO mice. Together, Mlk3KO mice was successfully generated by CRISPR/Cas9 system. MLK3 functions in maintaining blood pressure homeostasis by regulating MLC phosphorylation. This study provides an animal model for exploring the mechanism by which Mlk3 protects against the development of hypertension and hypertensive cardiovascular remodeling.

Effect of Home Blood Pressure Telemonitoring Plus Additional Support on Blood Pressure Control: A Randomized Clinical Trial / 生物医学与环境科学（英文）

OBJECTIVE@#Current clinical evidence on the effects of home blood pressure telemonitoring (HBPT) on improving blood pressure control comes entirely from developed countries. Thus, we performed this randomized controlled trial to evaluate whether HBPT plus support (patient education and clinician remote hypertension management) improves blood pressure control more than usual care (UC) in the Chinese population.@*METHODS@#This single-center, randomized controlled study was conducted in Beijing, China. Patients aged 30-75 years were eligible for enrolment if they had blood pressure [systolic (SBP) ≥ 140 mmHg and/or diastolic (DBP) ≥ 90 mmHg; or SBP ≥ 130 mmHg and/or DBP ≥ 80 mmHg with diabetes]. We recruited 190 patients randomized to either the HBPT or the UC groups for 12 weeks. The primary endpoints were blood pressure reduction and the proportion of patients achieving the target blood pressure.@*RESULTS@#Totally, 172 patients completed the study, the HBPT plus support group ( n = 84), and the UC group ( n = 88). Patients in the plus support group showed a greater reduction in mean ambulatory blood pressure than those in the UC group. The plus support group had a significantly higher proportion of patients who achieved the target blood pressure and maintained a dipper blood pressure pattern at the 12th week of follow-up. Additionally, the patients in the plus support group showed lower blood pressure variability and higher drug adherence than those in the UC group.@*CONCLUSION@#HBPT plus additional support results in greater blood pressure reduction, better blood pressure control, a higher proportion of dipper blood pressure patterns, lower blood pressure variability, and higher drug adherence than UC. The development of telemedicine may be the cornerstone of hypertension management in primary care.

Preliminary survey report on the clinical validation of in-use electronic sphygmomanometers in China / 中华心血管病杂志

Objective: To explore the percentage of in-use electronic sphygmomanometers independently validated clinically in China. Methods: We conducted a cross-sectional survey and Beijing, Shenzhen, Shijiazhuang, Datong, and Shihezi were selected according to the geographical location and economic level. In each site, one tertiary hospital, two community health centers, and 20 families with electronic sphygmomanometers in use were chosen. The information of electronic sphygmomanometers including brand, model, manufacturer and production date were obtained by the trained staff. Ten electronic sphygmomanometers from each hospital, five electronic sphygmomanometers from each community health center, and one electronic sphygmomanometer from each family were surveyed, and the user's subjective judgment results and judgment basis on the accuracy of the electronic sphygmomanometer measurement were collected. We searched six registration websites (Medaval, Stride BP, dabl Educational Trust, British and Irish Hypertension Society, American Medical Association and Hypertension Canada) and two research databases (PubMed and CNKI) for the clinical validation status of each electronic sphygmomanometer. Results: A total of 200 electronic sphygmomanometers were investigated in this study, of which only 29.0% (58/200) passed independent clinical validation. When stratified by users, the percentage of being clinical validated was 46.0% (23/50) for electronic sphygmomanometers in hospitals, 42.0% (21/50) for those in community health centers and 14.0% (14/100) for those in home use, respectively, and the proportions between the three groups were significantly difference (P<0.001). Doctors in tertiary hospitals and community health service centers judged the accuracy of electronic sphygmomanometers mainly on the basis of "regular correction" (41.0% (41/100)) and "comparison with other electronic sphygmomanometers" (20.0% (20/100)), while among home users, 41.0% (41/100) were not clear about the accuracy of electronic sphygmomanometers, and 40.0% (40/100) made the judgment by "comparison with the devices in hospitals". Conclusion: The clinical validation of in-use electronic sphygmomanometers in China is low. Most of users, including healthcare professionals, are not aware of clinical validation of electronic sphygmomanometers.

Associations of all-cause mortality with admission blood pressure variability during multiple hospitalizations in acute decompensated heart failure / 中华心血管病杂志

Objective: To investigate whether admission blood pressure (BP) variability during multiple hospitalizations is associated with all-cause mortality independent of baseline BP in acute decompensated heart failure (ADHF). Methods: Patients with ADHF admitted to the Department of Cardiology, The First Affiliated Hospital of Sun Yat-Sen University from September 2013 to December 2017 were retrospectively enrolled. The risk of all-cause mortality associated with indices of BP variability, including mean admission BPs, standard deviation of BP and coefficient of variation of BP during multiple hospitalizations was assessed, using Cox regression model. Results: A total of 1 006 ADHF patients (mean aged (69.3±13.5) years; 411 (40.8%) female; 670 (66.6%) with preserved ejection fraction) were enrolled. During a median follow-up of 1.54 years, 47.0% of patients died. In all ADHF patients, after adjusting for confounding factors, for every 1-standard deviation (SD) increase in SD and coefficient of variation (CV) of systolic BP, the risk of all-cause mortality increased by 10% and 11%, respectively (SD: HR, 1.10, 95%CI, 1.01-1.21, P=0.029, CV: HR, 1.11, 95%CI, 1.02-1.21, P=0.017); for every 1-SD increase in the mean of diastolic BP, the risk of all cause mortality decreased by 25% (HR, 0.75; 95%CI, 0.65-0.87; P<0.001). In ADHF patients with preserved ejection fraction, after accounted for potential confounders, higher SD and CV of admitted systolic and diastolic BP were significantly associated with higher risk of all-cause mortality, regardless of whether confounding factors were adjusted (P≤0.049); After adjusting for confounding factors, the risk of all-cause mortality increased by 18% and 19% for every 1-SD increase in SD and CV of systolic BP, while the risk of all-cause mortality increased by 11% and 15% for every 1-SD increase in SD and CV of diastolic BP. In ADHF patients with reduced ejection fraction, after adjusting for confounding factors, the higher the mean admission systolic BP during multiple hospitalizations, the lower the risk of total mortality (HR, 0.68; 95%CI, 0.47-1.00; P=0.049). Conclusions: In patients with ADHF, independent of baseline BP, BP variability during multiple hospitalizations was strong predictor of all-cause mortality.

Normotensive pheochromocytoma presenting as adrenal incidentaloma: A case report

Background@#Pheochromocytomas are rare catecholamine-secreting tumors that usually present with hypertension and palpitations. However, a subset of pheochromocytoma patients is asymptomatic, presenting as adrenal incidentaloma on imaging.@*Case@#We present a case of a 32-year-old normotensive female who presented with a right suprarenal mass on abdominal ultrasound. Diagnosis of pheochromocytoma was made after biochemical testing revealed elevated 24- hour urine metanephrine of 1.96 mg/24hrs (NV:0-1 mg/24hrs) and epinephrine of 129 mcg/24hrs (NV: 2-24 mcg/24hrs). In addition, plasma chromogranin A was elevated at 225.38 ng/ml (NV:<100 ng/ml). CT scan of the abdomen showed a 3.0 x 4.0 x 3.0 cm heterogeneous well-circumscribed right adrenal mass, with 87Hu on contrast, an absolute washout of 21%, and a relative washout of 13% on a delayed scan. After adequate preoperative medical therapy with an alpha-adrenergic blocker, a right laparoscopic adrenalectomy was done, with histopathologic confirmation of pheochromocytoma. Repeat 24-hour urine metanephrine measurements done on multiple follow-ups after surgery were normal.@*Conclusion@#Asymptomatic pheochromocytoma should be included in the differential diagnoses of adrenal incidentalomas. As in our case, patients with normotension and adrenal incidentalomas should still undergo biochemical workup to rule out the presence of pheochromocytoma. Long-term complications from chronic exposure to high catecholamine levels lead to significant adverse cardiovascular effects. Early detection, adequate perioperative preparation, and timely surgical intervention can prevent a potential catastrophe.

Low diastolic blood pressure and adverse outcomes in inpatients with acute exacerbation of chronic obstructive pulmonary disease: A multicenter cohort study / 中华医学杂志(英文版)

BACKGROUND@#Although intensively studied in patients with cardiovascular diseases (CVDs), the prognostic value of diastolic blood pressure (DBP) has little been elucidated in patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD). This study aimed to reveal the prognostic value of DBP in AECOPD patients.@*METHODS@#Inpatients with AECOPD were prospectively enrolled from 10 medical centers in China between September 2017 and July 2021. DBP was measured on admission. The primary outcome was all-cause in-hospital mortality; invasive mechanical ventilation and intensive care unit (ICU) admission were secondary outcomes. Least absolute shrinkage and selection operator (LASSO) and multivariable Cox regressions were used to identify independent prognostic factors and calculate the hazard ratio (HR) and 95% confidence interval (CI) for adverse outcomes.@*RESULTS@#Among 13,633 included patients with AECOPD, 197 (1.45%) died during their hospital stay. Multivariable Cox regression analysis showed that low DBP on admission (<70 mmHg) was associated with increased risk of in-hospital mortality (HR = 2.16, 95% CI: 1.53-3.05, Z = 4.37, P <0.01), invasive mechanical ventilation (HR = 1.65, 95% CI: 1.32-2.05, Z = 19.67, P <0.01), and ICU admission (HR = 1.45, 95% CI: 1.24-1.69, Z = 22.08, P <0.01) in the overall cohort. Similar findings were observed in subgroups with or without CVDs, except for invasive mechanical ventilation in the subgroup with CVDs. When DBP was further categorized in 5-mmHg increments from <50 mmHg to ≥100 mmHg, and 75 to <80 mmHg was taken as reference, HRs for in-hospital mortality increased almost linearly with decreased DBP in the overall cohort and subgroups of patients with CVDs; higher DBP was not associated with the risk of in-hospital mortality.@*CONCLUSION@#Low on-admission DBP, particularly <70 mmHg, was associated with an increased risk of adverse outcomes among inpatients with AECOPD, with or without CVDs, which may serve as a convenient predictor of poor prognosis in these patients.@*CLINICAL TRIAL REGISTRATION@#Chinese Clinical Trail Registry, No. ChiCTR2100044625.

Wearable sensing, big data technology for cardiovascular healthcare: current status and future prospective / 中华医学杂志(英文版)

Wearable technology, which can continuously and remotely monitor physiological and behavioral parameters by incorporated into clothing or worn as an accessory, introduces a new era for ubiquitous health care. With big data technology, wearable data can be analyzed to help long-term cardiovascular care. This review summarizes the recent developments of wearable technology related to cardiovascular care, highlighting the most common wearable devices and their accuracy. We also examined the application of these devices in cardiovascular healthcare, such as the early detection of arrhythmias, measuring blood pressure, and detecting prevalent diabetes. We provide an overview of the challenges that hinder the widespread application of wearable devices, such as inadequate device accuracy, data redundancy, concerns associated with data security, and lack of meaningful criteria, and offer potential solutions. Finally, the future research direction for cardiovascular care using wearable devices is discussed.

Effect of health management service for hypertension patients under framework of Basic Public Health Service Project: a regression discontinuity design / 中华流行病学杂志

Objective: To evaluate the effect of health management service on hypertension patients (HMSFHP) under the framework of the Basic Public Health Service Project by using regression discontinuity design. Methods: The participants were enrolled from an observational cohort survey in 2015 and followed up was conducted in 2019. The participants with SBP 130-150 mmHg and/or DBP 80-100 mmHg in the baseline survey of the cohort in 2015 were included in the present study. Additionally, we obtained the dates of participants receiving HMSFHP and their blood pressure data from follow-up records, physical examination records and telephone interview. The participants were divided into intervention group and control group based on the cutoff points, i.e. SBP ≥140 mmHg and/or DBP ≥90 mmHg. The local linear regression model were used to estimate the effect of HMSFHP on reducing blood pressure of the participants. Results: After adjusting for age, sex and time length of receiving HMSFHP, the results of the model including participants with 80-100 mmHg for DBP in 2015 indicated that, for the participants who received HMSFHP, the DBP decreased by 6.66 mmHg from 2015 to 2019. For the participants with SBP 130-150 mmHg in 2015, the reduction estimate of the model was -6.17 mmHg, the difference was not significant (P=0.178), suggesting that receiving HMSFHP did not cause change in SBP for the participants who received HMSFHP. Conclusion: Receiving HMSFHP had effect to reduce DBP, and HMSFHP had a positive effect on the control of blood pressure in patients with hypertension.

The distribution of blood pressure and associated factors of the elderly with type 2 diabetes in Jiangsu Province / 中华预防医学杂志

Objective: To investigate the distribution of blood pressure and analyze the associated factors of blood pressure of the elderly with type 2 diabetes in Jiangsu Province. Methods: The elderly over 60 years old participants with type 2 diabetes in the communities of Huai'an City and Changshu City, Jiangsu Province were selected in this study. They were divided into two groups: taking antihypertensive drugs and not taking antihypertensive drugs. The demographic characteristics, such as age and sex, and relevant factors were collected by questionnaire. The systolic blood pressure (SBP) and diastolic blood pressure (DBP) were measured by physical examination. The percentile of SBP and DBP in each age group of men and women were described. The kernel density estimation curve was used to show the blood pressure distribution. The trend of blood pressure with age was fitted by locally weighted regression. The logistic regression model was used to analyze relevant factors of blood pressure. Results: A total of 12 949 participants were included in this study, including 7 775 patients in the antihypertensive drug group and 5 174 patients in the group without antihypertensive drugs. The SBP of participants was concentrated at 140-160 mmHg, and their DBP was concentrated at 75-85 mmHg. There were significant differences in the distribution of blood pressure among the subgroups of body mass index (BMI) and rural areas whether taking antihypertensive drugs and not. For participants aged under 80 years old, the SBP showed an increasing trend with age and the DBP showed a decreasing trend with age. Age, BMI ≥24 kg/m2, fasting blood glucose ≥7.0 mmol/L, living in rural areas and no smoking were influencing factors of the elevated SBP; BMI ≥24 kg/m2, male, living in rural areas, no smoking, drinking alcohol and not receiving drug hypoglycemic treatment were influencing factors of the elevated DBP. Conclusion: The SBP of older diabetic adults in Jiangsu Province is at a high level, and the distribution of blood pressure is significantly different between men and women in taking antihypertensive drugs group. The SBP presents a rising trend and the DBP is decreasing at the age of 60-80 years. The blood pressure level of this population are mainly affected by age, BMI, urban and rural areas, smoking.

Guidelines for hypertension management in patients with chronic kidney disease in China (2023) / 中华肝脏病杂志

The population of chronic kidney disease (CKD) with hypertension in China is characterized by complex etiology, high incidence rate, low awareness and control rate. How to diagnose and treat hypertension in CKD patients properly and improve their prognosis is particularly urgent. Several clinical guidelines or expert consensus on the diagnosis, treatment and management of hypertension have been issued. Some of them involve the diagnosis and treatment of hypertension in CKD patients, but they still can not meet the demand for diagnosis and treatment of hypertension in CKD patients. Based on the situation of hypertension in CKD patients in China, the Chinese Society of Nephrology organized an expert group to formulate this guideline. This guideline systematically introduces the diagnostic criteria, epidemiology, risk factors, poor prognosis of hypertension, the purpose, timing and control goals of antihypertensive therapy in CKD patients, as well as blood pressure control goals for special populations, non drug treatment and drug treatment of hypertension. This guideline aims to further strengthen the management of hypertension in CKD patients, standardize the diagnosis and treatment standards, formulate reasonable treatment plans, effectively control hypertension, reduce complications, so as to delay the progress of kidney diseases and improve the long-term prognosis of hypertension in Chinese CKD patients.
