High-Risk Influential Factors for Cardiovascular Diseases among Young Adults.

The aim of this study was to compare high-risk influential factors for cardiovascular diseases among different young adults. It was a retrospective study carried out from January 2020 to 2022. A total of 700 young adults who underwent a physical examination or were hospitalised at the Baoding No.1 Central Hospital, Baoding, Hebei, P. R. China. The participants were divided into three groups: Young social health examinees (n = 300), who underwent physical examinations in January 2020; young medical workers (n = 300), young hospital employees who underwent physical examinations in January 2020; and young myocardial infarction patients (n = 100), who were hospitalised with myocardial infarction from January 2019 to 2021. Analysis was performed on the cardiovascular high-risk influential factors of different young adults. The proportions of males, smoking history, drinking history, hypertension history, lack of exercise, high stress, obesity, fatty liver levels of serum uric acid (UA), body mass index (BMI), diastolic blood pressure (DBP), systolic blood pressure (SBP), and weight in the young myocardial infarction patient group were higher than the other two groups while the HDL levels were lower than those of the latter two groups (p <0.05). The proportions of drinking history, hypertension history, lack of exercise, and high stress levels of UA, DBP, and SBP in the young medical worker group were higher than those in the young social health examinee group (p <0.05). Multivariate analysis revealed that males, high stress, obesity, high DBP and SBP levels were independent risk factors for cardiovascular diseases in young adults (p <0.05). High-risk influential factors of cardiovascular diseases in young adults include males, high stress, obesity, high blood pressure, etc. Key Words: Young people, Cardiovascular system, Medical workers, High-risk influential factors.

Examining the causal association between moderate alcohol consumption and cardiovascular risk factors in the Taiwan Biobank: a Mendelian randomization analysis.

The Mendelian randomization approach uses genetic variants as instrumental variables to study the causal association between the risk factors and health outcomes of interest. We aimed to examine the relation between alcohol consumption and cardiovascular risk factors using two genetic variants as instrumental variables: alcohol dehydrogenase 1B (ADH1B) rs1229984 and aldehyde dehydrogenase 2 (ALDH2) rs671. Using data collected in the Taiwan Biobank-an ongoing, prospective, population-based cohort study-our analysis included 129,032 individuals (46,547 men and 82,485 women) with complete data on ADH1B rs1229984 and ALDH2 rs671 genotypes and alcohol drinking status. We conducted instrumental variables regression analysis to examine the relationship between alcohol drinking and body mass index (BMI), systolic blood pressure (SBP), diastolic blood pressure (DBP), fasting glucose, glycated hemoglobin (HbA1c), triglycerides, high-density lipoprotein cholesterol (HDLc), and low-density lipoprotein cholesterol (LDLc). In the rs1229984-instrumented analysis, alcohol drinking was only associated with higher levels of SBP in men and lower levels of DBP in women. In the rs671-instrumented analysis, alcohol drinking was associated with higher levels of BMI, SBP, DBP, fasting glucose, triglycerides, HDLc and lower levels of LDLc in men; alcohol drinking was associated with higher levels of HDLc and lower levels of SBP, HbA1c, and triglycerides in women. Using Mendelian randomization analysis, some of our study results among men echoed findings from the previous systematic review, suggesting that alcohol drinking may be causally associated with higher levels of BMI, SBP, DBP, fasting glucose, triglycerides, HDLc, and lower levels of LDLc. Although alcohol drinking is beneficial to a few cardiovascular risk factors, it is detrimental to many others. The assumptions that underlie the Mendelian randomization approach should also be carefully examined when interpreting findings from such studies.

Sex differences in the association between chest computed tomography-defined sarcopenia and cardiovascular risk factors among inpatients.

While sarcopenia has been found to be associated with increased risks of cardiovascular diseases (CVDs), evidence exploring sex-related differences remains insufficient. This study aimed to investigate the differences in how often sarcopenia occurs in each sex, as determined by skeletal muscle area (SMA) in chest CT images, and its association with CVD common risk factors. This cross-sectional study involved 1,340 inpatients from the Department of Geriatrics of Renji Hospital, affiliated to Shanghai Jiaotong University School of Medicine. Data on age, sex, body mass index (BMI), smoking status, disease history, and clinical parameters were collected. Sarcopenia was defined using chest CT images with a cut-off value of T12-SMA/height2 <25.75 cm2/m2 in male patients and <20.16 cm2/m2 in female patients. Cardiovascular risk was assessed using the Framingham risk score (FRS). The association between T12-SMA/height2-defined sarcopenia and CVD risk factors by sex was evaluated using a multivariate logistic regression analysis. The overall prevalence of T12-SMA/height2-defined sarcopenia (<25.75 cm2/m2 for male patients, <20.16 cm2/m2 for female patients) was 54.03%, with 48.09% in male patients and 63.19% in female patients. The proportion of male patients with high CVD risk was greater than that of female patients. The multivariate analysis revealed that T12-SMA/height2-defined sarcopenia was independently associated with age (in male patients only), systolic blood pressure (SBP), cholesterol, and high-density lipoprotein cholesterol (HDL-C) among the six FRS cardiovascular risk indices. Our results suggest that T12-SMA/height2-defined sarcopenia was more prevalent in male patients than in female patients. Sarcopenia was associated with higher levels of SBP and HDL-C and lower levels of cholesterol. Increasing age had a more significant effect on CVD risk in male patients.

Clinical features most frequently present in patients with concomitant diabetic kidney disease and diabetic retinopathy.

To evaluate the profile of patients with diabetic kidney disease (DKD) with and without concomitant diabetic retinopathy (DR) to identify clinical predictors of the development of both complications together. Cross-sectional study including patients with type 1 and type 2 diabetes and DKD followed at the endocrinology division of a public hospital in Southern Brazil and referred for retinography assessment. The definition of DR was the occurrence of any diabetes-related damage identified in color fundus photographs under mydriasis. Urinary albumin excretion ≥ 14 mg/L and/or glomerular filtration rate < 60 mL/min/1.73 m2 (CKD-EPI equation) were used to define DKD. Factors evaluated included the clinical differences of the participants according to the presence or absence of DR. Multiple regression models were used to identify predictors of DR presence according to the clinical characteristics evaluated. The study included 517 patients with DKD, 433 (83.7%) of whom had type 2 diabetes (median age 64.7 years [interquartile range 59-73 years] years, 59.8% women, 83.4% white) and 84 (16.3%) had type 1 diabetes (median age 46.6 years [interquartile range 33.5-54.2 years], 46.4% women, 91.7% white). Patients with type 2 diabetes and DR (versus those without DR) were more often on insulin (odds ratio [OR] 3.63, 95% confidence interval [CI] 1.89-7.00), had diabetes for longer (OR 1.04, 95% CI 1.02-1.07), and had higher systolic blood pressure (OR 1.01, 95% CI 1.00-1.02). No predictors of DR presence were identified in participants with type 1 diabetes. Among patients with DKD and type 2 diabetes, insulin use, longer diabetes duration, and higher systolic blood pressure level were associated with the presence of DR.

#1202 Long-term evaluation of coronary calcifications in kidney transplanted patients: a single center follow up of 15 years

Abstract Background Patients with chronic kidney disease (CKD) have a relevant cardiovascular (CV) risk. Vascular calcification, particularly at coronary levels, have been related to the increased CV mortality. Few data are available on the long-term behavior of coronary artery calcifications (CAC) in kidney transplantation (KTx). In a previous paper (Alfieri C et al. Sci Rep. 2019 May 3;9(1):6869), our group explored the prevalence, the clinical and biochemical factors related with CAC and the factors implicated with CAC progression in a group of 64 KTx patients (KTXps) followed up for 5 years. Here we present the preliminary data about CAC follow up of the same population followed up for 15 years after KTx. Methods In 2007 we studied a total of 67 KTxps transplanted in our unit between 2007 and 2008. At the present time, 19 of them were lost from the follow up: 8 died, 4 because of major cardiovascular event (MACE), 11 KTxps had a graft loss and the other 20 did not adhere to the control. For this study, we evaluated 28 KTxps (M = 18; mean age 60 ± 9 yrs). Clinical parameters, blood and urinary analyses were recorded for 15 years, with particular attention for the year before CAC evaluation. For the statistical analysis the mean values of these evaluations were considered. At baseline and after 15 years from KTx, coronary TC for the evaluation of CAC using Agatson score was performed. According to the score obtained, patients were categorized in 4 groups both at baseline and at 15th year: 1) 0-10; 2) 10-100; 3) 100-400; 4) &amp;gt;400. The progression of CAC was determined considering the modification in CAC category (Cat-Prog+T15) and using the formula proposed by Sevrukov (AJR, 2005 Dec;185(6):1546-53) (Prog+). Results At baseline and at 15 yrs after KTx, 46% and 18% of pts were in the 1st group, 14% and 25% in the 2nd, 29% and 18% in the 3rd and 11% and 39% in 4th, respectively. CAC at 15yrs were significantly higher than baseline (156 ± 50 vs 334 ± 71 p &amp;lt; 0.0001). Both at baseline and after 15yrs CAC correlated directly with age (p = 0.0001; p = 0.01 resp.) and with each other (p &amp;lt; 0.0001). In the 79% Cat-Prog+T15 was found, in the 10,7% of more than 1 class of CAC. Prog+ was discovered in the 71% of KTxps. They were characterized to have higher systolic blood pressure levels (P = 0.05, with no difference in specific therapy), lower mean Hb and Ca levels (p = 0.02; p = 0.07 resp). In a logistic model, mean Ca Levels resulted the only independent factor inversely related with CAC15prog+ (p = 0.04). During the 15 years of KTx a MACE was experienced by the 25% of KTxps, just older than the others. Apparently, no impact for CACs was found in MACE. Conclusions To the best of our knowledge, our study is the first one to evaluate CACs in the same cohort of KTxps for such a long time. According to the preliminary data obtained, the prevalence of CAC in KTxps is quite high, and is related to age. CAC worsening, after 15 years of KTX was observed in a consistent part of the cohort and was related to different parameters, especially to Ca levels. Future researches, possibly involving a higher number of KTxps could explain better these findings and explore more deeply the relation of CACs with MACE in the long term.

Systolic blood pressure and risk of cardiovascular disease in normotensive diabetic adults: a prospective cohort study.

Currently, the special blood pressure (BP) target for normotensive diabetic patients has not been recommended. We investigated the optimal systolic blood pressure (SBP) for lower cardiovascular disease (CVD) risk in normotensive diabetic patients. In this 12-year follow-up study using the participants of the Kailuan Study, we mainly compared which SBP, 90-119 mmHg or 120-129 mmHg, had a lower risk of occurrence of CVD (stroke and myocardial infarction) in the 3072 normotensive diabetic participants and 21,532 normotensive and non-diabetic participants, respectively. The SBP was expressed as a mean time-weighted cumulative (MTWC) SBP, calculated from the multiple measurements of SBP during the follow-up. Multivariate competing risk regression analyses were used for the analysis. We found that in normotensive diabetic participants, MTWC SBP of 120-129 mmHg was associated with a lower risk of CVD (HR = 0.69 [0.50-0.95]), myocardial infarction (HR = 0.48 [0.24-0.96]), and trending towards lower risk of stroke (HR = 0.80 [0.55-1.16]), compared to MTWC SBP of 90-119 mmHg. Sensitivity analyses confirmed the relationship between low SBP and increased CVD risk. Whereas, in the normotensive and non-diabetic participants, MTWC SBP of 90-119 mmHg vs 120-129 mmHg did not exhibit any difference in the risk of CVD occurrence (HR = 0.99 [0.83-1.18]). The higher level of SBP in normotensive diabetic patients is especially associated with a lower risk of CVD occurrence.

ASSOCIATION BETWEEN TRAJECTORIES OF SYSTOLIC BLOOD PRESSURE AND FRAILTY OUTCOME IN MIDDLE-AGED AND OLDER ADULTS

Objective: The association between blood pressure and frailty outcome in the middle-aged and older population remains controversial. This study aimed to examine the relationship between trajectories of systolic blood pressure (SBP) and new-onset frailty. Design and method: From the China Health and Retirement Longitudinal Study, 6168 subjects were recruited in 2011 with follow ups in 2013, 2015 and 2018. The frailty index (FI) was constructed based on 40 scored items, with FI more than or equal to 0.25 defined as frailty. We identified the 5-year trajectory of SBP by latent class trajectory modeling. The association between SBP trajectories and frailty was explored based on hazard ratios (HR) by four Cox proportional hazards models. Restricted cubic splines were used to clarify the relationship between SBP and systolic blood pressure variability (SBPV) and frailty. Results: 6168 participants were included in this study with a mean age of 59 years. We identified five trajectories based on SBP, which are maintained low-stable SBP (T0), moderate-stable SBP (T1), remitting then increasing SBP (T2), increasing then remitting SBP (T3), and remaining stable at high SBP levels (T4). During the 7-year follow-up period, frailty outcome occurred in 1415 participants. After adjusting for other confounders, the two trajectories labeled “T2” and “T4” were associated with a higher risk of frailty compared with T0. In addition, elevated SBP and increased SBPV were associated with risk of frailty. Conclusions: Higher risk of frailty occurred in two trajectories, remitting then increasing and remaining stable at high SBP levels, were associated with a relatively higher risk of frailty.

Carotid artery ultrasonography and shear wave elastography in Takayasu's arteritis: a comparative analysis with diabetes mellitus.

Takayasu's arteritis (TAK) is a chronic inflammatory large vessel vasculitis with a grim prognosis due to the excessive risk for cardiovascular (CV) diseases. Its diagnosis relies on radiographic imaging and its differentiation particularly from atherosclerosis could be challenging. Hypothesising that vascular morphology observed in TAK would be comparable to that found in type 2 diabetes mellitus (T2DM), a prototype for advanced atherosclerosis, we compared two disease groups using carotid artery B mode US and shear wave elastography (SWE). A total of 72 patients with TAK (63F/9M; mean age: 42.7± 10.0 years) and 74 patients with T2DM (65F/9M; mean age: 50.2± 7.1 years) were studied. Intima-media thickness (IMT), outer diameter and arterial stiffness as assessed by SWE values were measured on the common carotid artery (CCA) and atherosclerotic plaques were recorded. Clinical characteristics, CV risk factors and previous history of CV diseases were determined. Framingham risk score was calculated. Patients with TAK exhibited significantly lower atherosclerotic risk but higher systolic blood pressure (BP) levels compared to those with T2DM. The mean values of CCA IMT, outer diameter, and stiffness were significantly elevated among patients with TAK compared to those with T2DM. Carotid artery plaques were evenly distributed between the study groups, but their anatomical localisation and composition differed significantly. While coronary artery disease (CAD) was more prevalent among T2DM patients, cerebrovascular diseases were more frequent among TAK patients. Our study revealed distinctive vascular alterations and atherosclerotic changes when compared to advanced atherosclerosis associated with T2DM. Apart from these, higher levels of systolic BP and significantly different distribution of CV diseases between TAK and T2DM also suggest that TAK should be handled with distinct assessment strategies than that employed in conventional atherosclerotic conditions.

Risk factors affecting the sleep quality of patients on dialysis: A single-center cross-sectional study.

Sleep quality is among the common complication in patients on dialysis and serious affect their health and quality of life; however, other associated risk factors are unclear. This study aimed to investigate the risk factors affecting sleep quality in patients on dialysis. Data were collected from 260 patients who met the inclusion criteria at out hospital from May 2023 to October 2023. Questionnaires were completed by patients, and biochemical indicators were obtained from past medical records. Univariate and multifactor analyses were used to find factors influencing sleep quality in patients on dialysis. Simple linear regression results showed that female, type of kidney primary disease, high systolic blood pressure (SBP), pruritus, pruritus frequency, restless legs syndrome (RLS), anxiety, and depression were associated with poor sleep quality. Blood biochemical parameters showed that low sodium and calcium levels and high ferritin levels were associated with poor sleep quality. Multiple linear regression statistics showed that female, pruritus, RLS, high SBP, depression, and high ferritin levels were associated with poor sleep quality. This study showed that female, chronic nephritis syndrome, high SBP, pruritus, RLS, low mood. and high ferritin levels were associated with poor sleep quality. Future development of individual nursing and targeted therapies is key to improving sleep quality in patients on dialysis.

Vitamin D deficiency and the vitamin D receptor (VDR) gene polymorphism rs2228570 (FokI) are associated with an increased susceptibility to hypertension among the Bangladeshi population.

Vitamin D receptor (VDR) gene is implicated in hypertension vulnerability due to its role in regulating the renin-angiotensin system (RAS) and blood pressure. In this case-control study, a carefully selected cohort of 111 hypertensive individuals and 100 healthy controls underwent serum analysis using HPLC to measure 25-hydroxy vitamin D levels. Polymorphic variations in the VDR gene were detected and characterized using the PCR-RFLP method. At first, lower 25-hydroxy vitamin D levels were observed in hypertensive individuals compared to controls (p<0.001). The genotype frequency of the VDR gene TaqI showed no significant difference between cases and controls (p>0.05). Similarly, no significant difference was found in the VDR gene BsmI genotype frequency between hypertensive patients and controls (p>0.05). However, a statistically significant distinction was observed in the VDR gene FokI genotype frequency between cases and controls (p<0.01). The odds ratios for FokI genotypes (CC, CT, TT, and CT+TT) were 1.0, 0.590, 1.566, and 0.963, respectively. Furthermore, serum 25-hydroxy vitamin D levels were significantly higher in control subjects compared to hypertensive patients across all genotypes of VDR (p<0.001). Hypertensive patients, excluding those with the FokI VDR gene CC genotype, exhibited significantly higher systolic blood pressure levels compared to the control group (p<0.05). Similarly, hypertensive subjects displayed elevated diastolic blood pressure levels compared to the control group (p<0.001). Overall, the results suggest the presence of a potential inverse correlation between serum 25-hydroxy vitamin D levels and hypertension. The association analysis conducted indicated that there is no significant association between TaqI and bsmI genotypic variants and the risk of developing hypertension. However, it was observed that VDR gene polymorphisms do have a clear association with hypertension susceptibility, as evidenced by the significantly higher occurrence of FokI genotypic variants in hypertensive patients. Our study therefore introduces the possibility of utilizing 25-hydroxy vitamin D deficiency and VDR gene polymorphisms as a biomarker for hypertension.

Association between trajectories of systolic blood pressure and frailty outcome in middle-aged and older adults

ObjectivesThe association between blood pressure and frailty outcome in the middle-aged and older population remains controversial. This study aimed to examine the relationship between trajectories of systolic blood pressure (SBP) and new-onset frailty. DesignCohort study with a 7-year follow-up. SETTING AND PARTICIPANTSData were derived from 4 waves (2011, 2013, 2015 and 2018) of the China Health and Retirement Longitudinal Study and 6168 participants aged ≥45 years were included in the study.

In addition, elevated SBP and increased SBPV were associated with risk of frailty. ConclusionsHigher risk of frailty occurred in two trajectories, remitting then increasing and remaining stable at high SBP levels, were associated with a relatively higher risk of frailty.

－75 G/A Polymorphism of Apolipoprotein A1 Gene Promoter Region in Normal Pregnant Women and Patients With Gestational Diabetes Mellitus

To investigate the －75 G/A single-nucleotide polymorphism in the promoter region of apolipoprotein A1 gene (apoA1) and its association with gestational diabetes mellitus (GDM) in pregnant women and to provide references for the exploration in the molecular genetic basis of GDM. A total of 626 GDM patients and 1022 normal pregnant women, ie, the controls, were included in the study. The genotyping of apoA1 －75 G/A polymorphism was performed by polymerase chain reaction and restriction fragment length polymorphism (PCR-RFLP) analysis. Total cholesterol (TC), triglycerides (TG), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), and glucose (Glu) were measured by enzymatic methods. Plasma insulin (INS) was measured by chemiluminescence immunoassay. The protein levels of apoA1 and apoB were measured by the turbidimetric immunoassay. Allele frequencies of G and A were 0.718 and 0.282 in the GDM group and 0.713 and 0.287 in the control group, respectively. Distribution of the genotype frequencies was found to be in Hardy-Weinberg equilibrium in both the GDM and control groups. There was no significant difference in the frequencies of alleles G and A and the genotypes of apoA1 －75 G/A polymorphism between the GDM and the control group (P>0.05). In the GDM group, the carriers with the genotype AA were associated with significantly higher levels of TC, HDL-C, and apoA1 than those with genotypes GG and GA did (all P<0.05). After the GDM patients were divided into obese and non-obese subgroups, the genotype-related apoA1 variation was observed only in obese patients, while the genotype-related TC and HDL-C variations were evident in non-obese patients (P<0.05). In the control group, carriers of genotypes AA and GA had higher systolic blood pressure (SBP) and HDL-C than the carriers of genotype GG did (all P<0.05). Carriers of genotypes AA had significantly lower Glu levels than carriers of genotypes GG and GA did (P<0.05). The control subjects were further divided into subgroups according to their body mass index (BMI). Analysis of the subgroups showed that AA carriers were associated with higher SBP levels in the obese control women only, while lower Glu levels were evident in both obese and non-obese control women. These results suggest that －75 G/A polymorphism in the apoA1 gene is not associated with GDM. However, the genetic variation is closed associated with the plasma apoA1, HDL-C, and TC levels in GDM patients and plasma HDL-C, Glu, and SBP levels in the control subjects. The apoA1 variant-associated lipids and SBP variation is BMI dependent in both groups.

Joint regression modeling of blood pressure and associated factors among adults in Uganda: Implications for clinical practice.

Blood pressure (BP) is a repeated measurement data as multiple measurements of both systolic blood pressure (SBP) and diastolic blood pressure (DBP) are simultaneously obtained on a patient to determine a raised blood pressure (hypertension). In examining factors associated with hypertension, BP is measured either as a binary outcome leading to information loss and reduced statistical efficiency or as a continuous outcome based on the average of one of the measurements or a combination of the two but independently thus ignoring possible correlation. We simultaneously modeled the risk factors for increased SBP and DBP among adults in Uganda and tested the difference in the effect of certain determinants on SBP versus DBP. We analyzed the 2014 nationwide non-communicable disease risk factor baseline survey data of Ugandans aged 18-69 years. We considered SBP and DBP as two continuous outcomes and conducted multivariate linear regression to jointly model SBP and DBP accounting for their distribution as bivariate normal. Of 3,646 participants, 950 (26.1%) had hypertension based on SBP (BP ≥ 140 mmHg) and DBP (BP ≥ 90 mmHg), 631 (17.3%) based on SBP alone, and 780 (21.4%) based on DBP alone. The study found that an increase in age (ranging from 18-69 years), obesity, income, being centrally obese, and hypercholesterolemia were significantly associated with higher SBP levels. Living in eastern, northern, and western Uganda regions was significantly associated with lower SBP, whereas increasing age, obesity, and hypercholesterolemia were significantly associated with higher DBP. Adults who rarely added salt to their meals were on average associated with higher DBP levels than those who never added salt to their meals. We found a strong residual correlation between SBP and DBP (r = 0.7307) even after accounting for covariates at the marginal level. This study presents a statistical technique for joint modeling of blood pressure, enabling the estimation of correlation between two outcomes and controlling family-wise error rate by testing the effect of a risk factor across both outcomes simultaneously.

Genetic Polymorphisms of Endothelial Nitric Oxide Synthase Associated with Hypertension and Blood Homocysteine Levels.

Endothelial dysfunction is a key mechanism in the development of hypertension and is closely linked to impairment of endothelial nitric oxide synthase (eNOS) and hyperhomocysteinemia. Genetic polymorphisms of eNOS (rs1799983 and rs2070744) are strongly associated with the risk of hypertension in individuals of Asian ethnicities. This study aimed to investigate the relationship between these polymorphisms and the risk of hypertension associated with homocysteine levels. For this cross-sectional study, we enrolled 370 Thai men aged 40-60 years from the Electricity Generating Authority of Thailand cohort study for both variants genotyping by TaqMan allelic discrimination analysis. Clinical, anthropometric, and biochemical parameters were also analyzed. In the high blood pressure group (n = 267), systolic and diastolic blood pressure and triglyceride levels were higher in those with homocysteine levels ≥ 15 µmol/L than in those with homocysteine levels < 15 µmol/L (p < 0.05). Significant risk of hypertension was found in GG and GT of rs1799983 (G894T), and in TT and TC of rs2070744 (T-786C), with higher ORs in heterozygous genotypes (all p values < 0.05). Further evaluation of the interactions between SNPs and HCY revealed that individuals with the GT or TC genotype, together with hyperhomocysteinemia, had an increased risk of hypertension (all p<0.05). eNOS variants rs1799983 and rs2070744 may be risk factors for hypertension linked to hyperhomocysteinemia. These findings provide potentially useful healthcare strategies for the management of hypertension.

Reperfusion status and postoperative blood pressure in acute stroke patients after endovascular treatment.

An aggressive lowering of blood pressure (BP) could lead to neurological worsening, particularly of the area that has not been reperfused in acute stroke patients with large vessel occlusion (LVO). We sought to investigate the association of reperfusion status and BP course following mechanical thrombectomy (MT) with outcomes in LVO. Consecutive patients with LVO treated with MT between Jan 2020 to Jun 2021 were enrolled in a retrospective cohort study. Hourly systolic BP (SBP) and diastolic BP (DBP) were recorded for 72 h following MT and maximum SBP and DBP levels were identified. The Extended Thrombolysis in Cerebral Infarction (eTICI) scale was used to assess reperfusion extent. LVO patients were stratified in 2 groups based on reperfusion status: complete reperfusion (eTICI 3) and incomplete reperfusion (eTICI 2b/c). Three-month functional independence was defined as a modified Rankin Scale score of 0-2. A total of 263 acute ischemic stroke patients with LVO were retrospectively evaluated. Complete reperfusion was achieved in 210 patients (79.8%). Post-MT maximum SBP over 160 mmHg was significantly related to worse functional outcome (38.1% vs. 55.7%, p = 0.006), higher likelihood of in-hospital mortality and 3-month mortality (19.0% vs. 6.9%, p = 0.004, 27.4% vs. 14.3%, p = 0.012). No statistical correlation was found between reperfusion status and blood pressure level (p > 0.05). In patients with complete reperfusion, patients with an average BP 120-140 mmHg tends to have worse functional outcome compared with 100-120 mmHg (OR = 1.77, 95%CI: 0.97-3.23, p = 0.061). High maximum SBP levels following MT are associated with an increased likelihood of 3-month functional dependence and mortality. An average BP of 100-120 mmHg tends to have better functional independence in completely reperfused patients. The effect of intensive BP control on incomplete reperfusion still warrants further investigations.

Value of Hcy combined with Framingham score for predicting macrovascular disease in elderly patients with type 2 diabetes.

To analyze the predictive value of homocysteine (Hcy) combined with the Framingham risk score for cardio- and cerebrovascular disease in elderly patients with type 2 diabetes mellitus (T2DM) to provide a reference for clinical treatment. We retrospectively reviewed the clinical data of 1036 elderly patients with T2DM admitted to our hospital between July 2017 and July 2022. The patients were divided into occurrence (n = 438) and control (n = 598) groups based on the incidence of cardio- or cerebrovascular disease. Univariate and multivariate logistic analyses were used to analyze the factors associated with cardio-cerebral small-vessel disease in the elderly patients with T2DM. The predictive value of Hcy combined with the Framingham score for cardio- and cerebrovascular diseases in elderly patients with T2DM was determined using receiver operating characteristic curves. Univariate analysis showed that the occurrence group had significantly higher Framingham score, systolic blood pressure (SBP), total cholesterol (TC), fasting blood glucose (FBG), 2-hour postprandial plasma glucose, Hcy, glycated hemoglobin, smoking history, and disease duration than the control group (all P < .05). Food preferences, sleep duration, physical exercise, high density lipoprotein cholesterol (HDL-C), and low-density lipoprotein cholesterol levels were significantly lower in the occurrence group than in the control group (all P < .05). Multivariate logistic analysis showed that smoking history, duration of diabetes, Framingham score, SBP, TC, FBG, HDL-C, 2h postprandial plasma glucose, and Hcy levels were risk factors for cardio- and cerebrovascular disease in elderly patients with T2DM. The area under the curve for Hcy and Framingham scores was 0.741 (95% confidence interval [CI]: 0.635-1.871) and 0.717 (95% CI: 0.601-0.856), respectively. Hcy combined with the Framingham score demonstrated a significantly higher predictive value (0.852, 95% CI: 0.741-0.979). Long smoking history, long diabetes duration, high Framingham score, high SBP, high TC, high FBG, low HDL-C, and high Hcy levels are risk factors for cardio-cerebrovascular disease in elderly patients with T2DM. In addition, Hcy level combined with the Framingham score demonstrated superior predictive power for cardio- and cerebrovascular disease in elderly patients with T2DM.

Evaluation of Blood Sugar, Blood Pressure and Foot Health in Individuals Not Diagnosed with Diabetes, Hypertension

Objective: Diabetes Mellitus constitutes a significant health concern given its incidence and associated complications. Furthermore, obesity, being a chronic disease, represents a risk factor for hypertension, cardiovascular diseases, and diabetes. In light of these considerations, our study aims to perform a public screening for conditions that are closely related, including hypertension, obesity, diabetes, and foot health. Methods: The study was conducted over a three-day period from September 12 to September 15, 2017, between the hours of 09:00-17:00. The sample comprised of volunteers who passed by the established stands and were not diagnosed with diabetes or hypertension. Blood glucose levels (BG) were measured using a glucometer, while weight and height were measured using a scale. Waist circumference was measured using a tape measure, and foot examinations were conducted using a podoscope. In addition, a questionnaire was administered to gather sociodemographic information and health-related data from participants. Measurements were taken of random capillary BG, blood pressure (BP), height, weight, and waist circumference. A general foot examination was performed, and any pressing foot issues were evaluated with a podoscope. Results: In our study, the mean BG level of 428 participants was 126 g/dl, with 7% of them recording BG levels above 200 g/dl. During foot examinations, 29% of participants reported experiencing pain, while 26% had issues with false nail clipping. Pes planus was detected in 14% of individuals during podoscopic examination, and it was observed that those who used sports shoes and those who had previous foot examinations had fewer foot health problems. Additionally, individuals with high BMI values exhibited a higher prevalence of claudication findings, ingrown nails, and dryness and cracks in the skin. Participants with higher systolic BP were found to have more instances of ingrown nails and other nail problems, including interdigital maceration. Conclusion: The selection of appropriate footwear and regular foot examinations are crucial in the prevention of foot health problems. Our study found a significant association between foot health problems and high BMI and systolic blood pressure levels.

FEASIBILITY AND MEASUREMENT STABILITY OF SMARTWATCH-BASED CUFFLESS BLOOD PRESSURE MONITORING

Objective: Cuffless wearable devices are currently being developed for long-term monitoring of blood pressure (BP) in patients with hypertension and in apparently healthy people. This study evaluated the feasibility and measurement stability of smartwatch-based cuffless BP monitoring in real-world conditions. Design and method: Users of the first smartwatch-based cuffless BP monitor approved in Korea (Samsung Galaxy Watch) were invited to upload their data from using the device for 4 weeks post calibration. Results: A total of 760 participants (mean age 43.7±11.9, 80.3% men) provided 35,797 BP readings (average monitoring 22±4 days [SD]; average readings 47±42 per participant [median 36]). Each participant obtained 1.5±1.3 readings/day and 19.7% of the participants obtained measurements every day. BP showed considerable variability, mainly depending on the day and time of the measurement. There was a trend towards higher BP levels on Mondays than on other days of the week and on workdays than in weekends. BP readings taken between 00:00 and 04:00 tended to be the lowest, whereas those between 12:00 and 16:00 the highest. The average pre-post calibration error for systolic BP (difference in 7-day BP before and after calibration), was 6.8±5.6 mmHg, and was increased with higher systolic BP levels before calibration. Conclusions: Smartwatch-based cuffless BP monitoring is feasible for out-of-office monitoring in the real-world setting. The stability of BP measurement post calibration and the standardization and optimal time interval for recalibration need further investigation.

CENTRAL AND PERIPHERAL HAEMODYNAMIC RESPONSE TO COFFEE CONSUMPTION IN THE COHORT OF THE BRISIGHELLA HEART STUDY

Objective: Even though coffee consumption has been clearly related to a number of benefits on the cardiovascular system, its effect on blood pressure (BP) has not been fully elucidated. Design and method: In this sub-analysis of the Brisighella Heart Study (BHS), we assessed the central and peripheral BP response to coffee drinking in a sub-cohort of 720 men (47.9%) and 783 women (52.1%), for whom a full set of clinical, laboratory and haemodynamic parameters was available. Results: According to our observations, moderate coffee drinking was associated to either higher levels of systolic BP (SBP) compared to heavy coffee consumption and lower SBP than non-coffee drinking (p-value for trend &lt;0.05). In particular, people who drank 2 cups of coffee per day and people who drank &gt;3 cups per day had respectively 5.2 ± 1.6 mmHg (p = 0.010) and 9.7 ± 3.2 mmHg (p = 0.007) lower SBP than non-coffee drinkers. Similar trends were also observed for peripheral pulse pressure (PP), aortic BP and aortic PP. In the age-adjusted multiple linear regression model, negative predictors of SBP, PP, aortic BP and aortic PP were the estimated glomerular filtration rate (eGFR), female sex and coffee consumption. Positive predictors included body mass index (BMI) and low-density lipoprotein cholesterol (LDL-C). Conclusions: Our findings show that regular coffee drinking lowers SBP, PP, aortic BP and aortic PP, without having any effect on arterial stiffness.

Volunteering and Changes in Cardiovascular Biomarkers: Longitudinal Evidence From the Health and Retirement Study.

Growing body of research shows that volunteering is beneficial for those served, the volunteers, and the larger communities. However, major challenges remain that hinder the practical implications for volunteer activity as a public health intervention, including potential selection effects, lack of longitudinal studies that adjust for baseline characteristics, and a paucity of studies that consider multiple physical health outcomes in a single model. Data from 2006 to 2016 waves of the Health and Retirement Study (2006-2016) were used (N = 18,847). Outcome-wide analyses were utilized to evaluate if changes in volunteering between 2006/2008 (t0) and 2010/2012 (t1) were associated with 7 cardiovascular disease biomarkers 4 years later (2014/2016, t2). These models were adjusted for demographic factors, socioeconomic status, health behaviors, chronic conditions, baseline biomarkers, and volunteering. Additionally, selection into volunteering and attrition were taken into account. Compared with nonvolunteers, volunteering more than 200 hr a year was associated with a lower risk for clinically high diastolic blood pressure. In addition, increased volunteering effort (change from 1 to 99 hr at t0 to >100 hr at t1) was associated with a lower likelihood of clinically high systolic and diastolic blood pressure levels. Sustained high volunteering (>100 hr at both t0 and t1) was associated with lower diastolic blood pressure. The current study adds to the evidence on the health benefits of volunteering for adults 50 and older by inferring a potential causal link between high-intensity volunteering and reduced blood pressure.
