Objective:To explore the association between uric acid and new-onset chronic kidney disease (CKD) in middle-aged and elderly hypertensive patients.Methods:This was a retrospective cohort study. Middle-aged and elderly hypertensive patients who had attended at least two annual health examinations at Yongshun Community Health Service Center in Tongzhou District, Beijing, from June 2016 to December 2020 were enrolled. The time interval between the two physical examinations was three years. The first physical examination time served as the baseline, and the second as the end of follow-up. Based on the uric acid level at baseline, the participants were divided into the normal uric acid group and the hyperuricemia group. The relevant clinical data of the participants were collected. The endpoint of the study was new-onset CKD. A multivariate logistic regression model was used to analyze the association between uric acid and new-onset CKD in hypertensive patients.Results:A total of 2 472 middle-aged and elderly hypertensive patients with an average age of (62.43±7.02) years were included. Of these, 733(29.7%) were male. There were 710 patients with hyperuricemia (hyperuricemia group) and 1 762 patients with normal uric acid levels (normal uric acid group).After adjusting for age, sex, body mass index (BMI), systolic blood pressure, diabetes mellitus, estimated glomerular filtration rate (eGFR), and uric acid-lowering treatment, multivariate logistic regression analysis showed that combined with hyperuricemia was an independent risk factor for new-onset CKD in middle-aged and elderly hypertensive patients ( OR=3.00, 95% CI: 1.87-4.80, P<0.001). The results of multivariate logistic analysis showed that elevated uric acid level was an independent risk factor for new-onset CKD in both male and female middle-aged and elderly hypertensive patients (both P<0.05), and there was no sex interaction ( P for interactio n>0.05). The results of multivariate logistic analysis showed that the combination of asymptomatic hyperuricemia was an independent risk factor for new-onset CKD in middle-aged and elderly hypertensive patients ( OR=3.00, 95% CI: 1.87-4.80, P<0.001), and there was no gender interaction ( P for interactio n>0.05). Conclusions:Hyperuricemia is an independent risk factor for new-onset CKD in middle-aged and elderly hypertensive patients, and elevated uric acid levels increase the risk of new-onset CKD in both male and female patients. Moreover, asymptomatic hyperuricemia may increase the risk of new-onset CKD.

BACKGROUND: The benefits of ideal cardiovascular-health metrics (ICVHMs) in patients with renal insufficiency remain unclear. This study aimed to investigate the associations between ICVHM and prognosis in a renal insufficiency population. METHODS: The trial enrolled 29,682 participants from the US National Health and Nutrition Examination Survey (NHANES), 2007-2018, with mortality follow-up through December 31, 2019. Participants were divided into three groups based on estimated glomerular filtration rates. Cardiovascular health was assessed using new "Life's Essential 8" metrics. Cox regression analyses based on NHANES data were used to determine the associations between ICVHMs and cardiovascular mortality in patients with renal insufficiency. RESULTS: During a mean follow-up of 6.58 years, ideal cardiovascular health (hazard ratio [HR] = 0.42; 95% confidence interval [CI]; 0.25-0.70) and ideal health behavior (HR = 0.53; 95% CI; 0.39-0.73) reduced cardiovascular mortality in participants with renal insufficiency. For each one ICVHM increment, a 25% reduction in cardiovascular mortality was recorded (95% CI; 0.69-0.82). When compared with participants with normal renal function, for those with mild renal insufficiency, the HR for cardiovascular mortality gradually decreased from 1.47 (95% CI; 0.85-2.52) in those who had ≤1 ICVHMs to 0.30 (95% CI; 0.12-0.77) in participants who had >6 ICVHMs. CONCLUSIONS From an ICVHM perspective, enhanced cardiovascular benefits were observed in individuals with renal insufficiency, coupled with a reduced risk of all-cause mortality. Furthermore, when compared with individuals with normal renal function, increased ICVHMs can mitigate adverse risks associated with renal impairment.

Background::Although multiple measures of blood pressure variability (BPV) have been proposed, whether they are better than mean blood pressure in predicting target organs is unclear. We aimed to determine the relationship between short term BPV and target organ injury.Methods::This study was a retrospective study, and 635 inpatients in the Department of Cardiology from 2015 to 2020 were selected. We divided participants into four groups on the basis of the quartiles of BPV. One-way analysis of variance was used to compare the differences between the groups, and linear regression was used to analyze the relationship between BPV and target organ damage.Results::The average age of 635 patients was 74.36 ± 6.50 years old. Among them, 354 of 627 patients had diminished renal function (56.5%), 221of 604 patients had associated left ventricular hypertrophy (36.6%), and 227 of 231 patients had carotid plaque formation (98.3%). The baseline data indicated significant differences in fasting glucose, total cholesterol, low-density lipoprotein, creatinine, glomerular filtration rate, sex, calcium channel blocker use, and the rate of diminished renal function. Multiple linear regression analysis showed that BPV was negatively correlated with renal injury (creatinine: r= 0.306, p < 0.01; estimated glomerular filtration rate: r = 0.058, p < 0.01), and BPV is positively correlated with cardiac injury ( r= 0.083, p < 0.01). Elevated BPV was not found to be associated with vascular injury. Conclusion::Renal function decreases with increasing BPV and left ventricular mass increases with increasing BPV.

BACKGROUND: Limited data are available on the comparison of clinical outcomes of complete vs. incomplete percutaneous coronary intervention (PCI) for patients with chronic total occlusion (CTO) and multi-vessel disease (MVD). The study aimed to compare their clinical outcomes. METHODS: A total of 558 patients with CTO and MVD were divided into the optimal medical treatment (OMT) group ( n = 86), incomplete PCI group ( n = 327), and complete PCI group ( n = 145). Propensity score matching (PSM) was performed between the complete and incomplete PCI groups as sensitivity analysis. The primary outcome was defined as the occurrence of major adverse cardiovascular events (MACEs), and unstable angina was defined as the secondary outcome. RESULTS: At a median follow-up of 21 months, there were statistical differences among the OMT, incomplete PCI, and complete PCI groups in the rates of MACEs (43.0% [37/86] vs. 30.6% [100/327] vs. 20.0% [29/145], respectively, P = 0.016) and unstable angina (24.4% [21/86] vs. 19.3% [63/327] vs. 10.3% [15/145], respectively, P = 0.010). Complete PCI was associated with lower MACE compared with OMT (adjusted hazard ratio [HR] = 2.00; 95% confidence interval [CI] = 1.23-3.27; P = 0.005) or incomplete PCI (adjusted HR = 1.58; 95% CI = 1.04-2.39; P = 0.031). Sensitivity analysis of PSM showed similar results to the above on the rates of MACEs between complete PCI and incomplete PCI groups (20.5% [25/122] vs. 32.6% [62/190], respectively; adjusted HR = 0.55; 95% CI = 0.32-0.96; P = 0.035) and unstable angina (10.7% [13/122] vs. 20.5% [39/190], respectively; adjusted HR = 0.48; 95% CI = 0.24-0.99; P = 0.046). CONCLUSIONS For treatment of CTO and MVD, complete PCI reduced the long-term risk of MACEs and unstable angina, as compared with incomplete PCI and OMT. Complete PCI in both CTO and non-CTO lesions can potentially improve the prognosis of patients with CTO and MVD.

Objective:To investigate the association between plasma uric acid and hypertension and the gender difference in community-dwelling middle-aged and elderly population.Methods:A community-based cross-sectional study was conducted in Beijing Tongzhou Yongshun Community Health Service Center from June to December 2021, among residents aged 45 years or older selected by cluster sampling method. According to plasma uric acid (UA) level in quartiles, the subjects were divided into 4 groups; and stratified by gender, the subjects were further divided into subgroups. Multivariate logistic regression model was used to analyze the related factors of hypertension, and restricted cubic spline fitting logistic regression model was used to analyze the nonlinear association between uric acid and hypertension and the cut-off values of uric acid.Results:A total of 6 229 residents with the age of (63.2±7.3) years were enrolled in the study. In 1 874 male participants (30.1%), 946 participants (50.5%) had hypertension, and the uric acid level was 359 (309, 418)μmol/L; in 4 355 female participants (69.9%), 2 003 participants (46.0%) had hypertension, and the uric acid level was 306 (261, 359)μmol/L. Multivariate logistic regression analysis showed that after adjusting for factors that were statistically significant in univariate analyses or potentially clinically relevant (including age, body mass index, diabetes mellitus, coronary heart disease, cerebrovascular disease, albumin, estimated glomerular filtration rate, and cholesterol), uric acid was independently associated with hypertension ( P<0.001), for total participants the risk of hypertension in Q4 group was 1.33 times of that in Q1 group ( OR=1.33,95% CI 1.13-1.56, P=0.001); while for females the risk of hypertension in Q4 group was 1.38 times of that in Q1 group ( OR=1.38,95% CI 1.13-1.68, P=0.002), but no significant association was observed for males ( P>0.05). The results of restricted cubic spline fitting logistic regression analysis showed that there was a linear association between uric acid level and hypertension in the total population and males, and the risk of hypertension increased with uric acid level ( P<0.001 for the total population, P=0.016 for male). However, there was a non-linear association in females. When uric acid>307 μmol/L in females, the risk of hypertension increased significantly as the level of uric acid increased ( P<0.001). Conclusions:Uric acid level was independently associated with hypertension in the community-dwelling middle-aged and elderly population, and there was a gender difference in the correlation. The association was nonlinear in females and the cut-off value of uric acid in females was 307 μmol/L.

Objective:To explore the relationship between the triglyceride glucose (TyG) index and impairment of renal function in community-dwelling middle-aged and elderly population.Methods:A total of 4 988 residents aged ≥45 years undergoing health check-up in Yongshun Health Service Center from January 2016 to December 2021 were enrolled and followed up. According to the quartile of the baseline TyG index, all subjects were divided into Q1, Q2, Q3 and Q4 groups. The medical history, physical examination and laboratory test results were documented. Participants were followed up through regular health check-up until March 31, 2023. The outcomes were rapid decline of estimated glomerular filtration rate (eGFR) (a loss in eGFR>3 ml·min -1·1.73 m -2 per year) and the new-onset of chronic kidney disease (CKD) during the follow-up period. Linear regression model, multivariate logistic regression model, restricted cubic spline fitting logistic regression model and ROC curve analysis were used to analyze the association between the TyG index and the impairment of renal function. Results:Among 4 988 residents, 1 396 (28.0%) were males and the age was (59.76±6.28) years. There were 1 247 participants in Q1, Q2, Q3 and Q4 groups, respectively. After 56 months of follow-up, the incidence of rapid eGFR decline and new-onset CKD was 21.9% (1 294/4 988) and 4.0% (200/4 988), respectively. Multivariate logistic regression model analysis showed that TyG index was correlated positively with rapid eGFR decline and new-onset of CKD ( OR=1.34, 95%CI: 1.17-1.52, P<0.001, and OR=1.57, 95%CI:1.19-2.06, P=0.001). Taking group Q1 as a reference, higher levels of TyG index ( Q2, Q3 and Q4 groups) was an independent risk factor for rapid eGFR decline ( P<0.05), which has a dose-response relationship (for trend P=0.002). Compared with the lowest quartile, the adjusted OR of new-onset CKD in the highest quartile was 1.85 ( 95%CI:1.13-3.03, P=0.014). The results of restricted cubic spline fitting logistic regression analysis showed a linear association between TyG index and both outcomes (both P>0.05). The area under ROC curve ( AUC) of the TyG index for predicting the two adverse outcomes were 0.536 ( 95%CI: 0.516-0.556, P<0.001) and 0.588 ( 95%CI:0.548-0.627, P<0.001), respectively. Conclusion:The elevated levels of TyG index may be used as an independent predictor of rapid eGFR decline and new-onset CKD.

BACKGROUND: Atherosclerosis-related diseases represent significant health issues among adults globally. Despite their widespread impact, comprehensive data concerning the global and national burden and trends of these diseases remain sparse. Our objective is to examine the trends in the burden of atherosclerosis among adults from 1990 to 2019 at both global and national levels. METHODS: We reported the average annual percentage changes (AAPCs) in prevalence, incidence, mortality, and disability-adjusted life years (DALYs) of atherosclerosis-related diseases (ischemic heart disease [IHD], ischemic stroke, and peripheral arterial disease [PAD]) at the global and national levels among individuals based on a trend analysis of the Global Burden of Diseases Study (GBD) 2019. We further analyzed these global trends as a function of age, gender, and the social development index. We also used joinpoint regression analysis to identify the year with the most substantial changes in global trends. RESULTS: Globally, the AAPC of IHD incidence rose from 1990 to 2019 (0.20; 95% confidence interval [CI], 0.12-0.28), with substantial surges in 1995, 2001, 2005, 2010, and 2017. Conversely, AAPC of IHD mortality rates exhibited a different trend until a rise in 2014. The AAPC of incidence rates of ischemic stroke and PAD also escalated during the same period, with respective 0.43 (95% CI, 0.39-0.48) and 0.13 (95% CI, 0.06-0.21). For ischemic stroke, both incidence and mortality soared in 2014, while PAD incidence declined in 1994 and 1998, then sharply climbed in 2016. Nationally, the Northern Mariana Islands experienced the steepest increase in IHD and PAD incidence and mortality between 1990 and 2019. China saw a significant rise in ischemic stroke incidence, whereas the highest mortality rate increase occurred in Timor-Leste. By sociodemographic index (SDI) quintile, low-middle-, middle-, and high-middle-SDI countries all showed upward trends in IHD, ischemic stroke, and PAD incidence. Simultaneously, IHD and ischemic stroke mortality rates, as well as DALYs, dropped in the low-, high-middle-, and high-SDI nations. However, PAD mortality rates and DALYs saw an uptick across all SDI quintiles. Regarding age demographics, a global decrease in the AAPC IHD incidence as noted in individuals above 55 years old, in contrast to an increase in the 20-55 age group during this period. AAPC of mortality rates for IHD, ischemic stroke, and PAD decreased across all ages. The AAPC showed an increase in IHD incidence in both genders. Conversely, IHD's DALYs saw a reduction in both males and females. Ischemic stroke patterns mirrored these trends, whereas all measures for PAD exhibited growth for both sexes. CONCLUSIONS From 1990 to 2019, there was an overall increasing trend in the global incidence of all three clinical manifestations of atherosclerosis. Between 1990 and 2019, both the mortality rate and DALYs for IHD and ischemic stroke declined across all age groups. Overall, the burden of atherosclerosis-related diseases has not significantly decreased and even shows signs of trending upward. These findings strongly suggest that despite some progress made, efforts to control atherosclerosis diseases globally need to be intensified.

Elevated BPV was not found to be associated with vascular injury. Conclusion::Renal function decreases with increasing BPV and left ventricular mass increases with increasing BPV.

Background::Chronic total occlusion (CTO) is a critical and unique subgroup of coronary lesions. This study aimed to investigate the correlation between the Selvester QRS score and late gadolinium enhancement cardiac magnetic resonance imaging (LGE-CMRI) in quantifying myocardial scarring to provide a simple and feasible method for treating CTO.Methods::The medical records of 134 patients with absolute CTO who underwent coronary angiography between May 1, 2014 and December 30, 2017 were retrospectively reviewed. All patients were grouped according to the CTO location (right coronary artery [RCA] CTO, left artery descending [LAD] CTO, left circumflex [LCX] CTO, and multivessel CTO groups). The degree of myocardial scarring was determined according to the Selvester QRS score and using the LGE-CMRI. All patients were followed up for at least 12 months.Results::Among the 62 CTO patients, 55 had occlusion of a single vessel and seven had occlusion of multiple vessels, of which 27 (43.55%) were in the RCA CTO group, 16 (25.81%) in the LAD CTO group, 12 (19.35%) in the LCX CTO group, and 7 (11.29%) in the multivessel CTO group. The area under the receiver operating characteristic curve for the QRS score that was used to determine the degree of myocardial scarring was 0.806, with a sensitivity and specificity of 94.7% and 42.1%, respectively. The Selvester QRS score and LGE-CMRI measures of scar size were correlated in the RCA CTO, LCX CTO, and multivessel CTO groups ( r = 0.466, 0.593, and 0.775, respectively). Conclusion::The Selvester QRS score was feasible for detecting myocardial scarring in patients with CTO.
