RESUMEN
To explore the effect of different levels of systolic blood pressure (SBP) control on new-onset chronic kidney disease in hypertension multimorbidity. The hypertensive patients with multimorbidity information were enrolled from the Kailuan Study. The isolated hypertension patients undergoing physical examination during the same period were selected in a 1:1 ratio as control. Finally, 12,897 participants were divided into six groups: Group SBP < 110 mmHg, Group 110 ≤ SBP < 120 mmHg, Group 120 ≤ SBP < 130 mmHg, Group 130 ≤ SBP < 140 mmHg, Group 140 ≤ SBP < 160 mmHg and Group SBP ≥ 160 mmHg. The outcomes were new-onset CKD, new onset proteinuria, decline in eGFR and high or very high risk of CKD. Cox proportional hazards regression was used to examine the hazard ratios (HRs) of the outcomes among SBP levels. When 110 ≤ SBP < 120 mmHg, the incidence density of new-onset CKD, new onset proteinuria and decline in eGFR were 59.54, 20.23 and 29.96 per 1000 person-years, respectively. Compared to this group, the HR (95% CI) values for the risk of new-onset CKD from Group SBP < 110 mmHg to Group SBP ≥ 160 mmHg were 1.03 (0.81-1.32), 1.04 (0.91-1.19), 1.09 (0.95-1.16), 1.16 (1.02-1.21) and 1.18 (1.04-1.24), respectively. For patients over 65 years old, the risks of outcomes were increased when SBP < 120 mmHg. The lowest HR of high or very high risk of CKD for participants with or without multimorbidity occurred when 120 ≤ SBP < 130 mmHg. The HR of new-onset CKD in hypertension multimorbidity was lowest at 110-120 mmHg. The optimal SBP level was between 120 and 130 mmHg for individuals with high or very high risk of CKD. For patients over 65 years old, the low limit of target BP is advised to be not lower than 120 mmHg.

BACKGROUND: The atherogenic index of plasma (AIP) has been shown to be positively correlated with cardiovascular events. However, it remains unclear whether hypertensive patients with long-term high AIP levels are at greater risk of developing heart failure (HF). Therefore, the aim of this study was to investigate the association between AIP trajectory and the incidence of HF in hypertensive patients. METHODS: This prospective study included 22,201 hypertensive patients from the Kailuan Study who underwent three waves of surveys between 2006 and 2010. Participants were free of HF or cancer before or during 2010. The AIP was calculated as the logarithmic conversion ratio of triglycerides to high-density lipoprotein cholesterol. Latent mixed modeling was employed to identify different trajectory patterns for AIP during the exposure period (2006-2010). Cox proportional hazard models were then used to estimate the hazard ratio (HR) and 95% confidence interval (CI) for incident HF among different trajectory groups. RESULTS: Four distinct trajectory patterns were identified through latent mixture modeling analysis: low-stable group (n = 3,373; range, -0.82 to -0.70), moderate-low stable group (n = 12,700; range, -0.12 to -0.09), moderate-high stable group (n = 5,313; range, 0.53 to 0.58), and elevated-increasing group (n = 815; range, 1.22 to 1.56). During a median follow-up period of 9.98 years, a total of 822 hypertensive participants experienced HF. After adjusting for potential confounding factors, compared with those in the low-stable group, the HR and corresponding CI for incident HF in the elevated-increasing group, moderate-high stable group, and moderate-low stable group were estimated to be 1.79 (1.21,2.66), 1.49 (1.17,1.91), and 1.27 (1.02,1.58), respectively. These findings remained consistent across subgroup analyses and sensitivity analyses. CONCLUSION: Prolonged elevation of AIP in hypertensive patients is significantly associated with an increased risk of HF. This finding suggests that regular monitoring of AIP could aid in identifying individuals at a heightened risk of HF within the hypertensive population.

Systolic blood pressure (SBP) time in target (TTR) over months were associated with lower risk of adverse clinical outcomes in hypertensive patients, whether short-term of 24-h SBP TTR was effective in predicting heart failure (HF) risk in the general population remained unclear. This prospective study aimed to investigate the association of 24-h SBP TTR with HF in the real-world settings. Based on Kailuan study, 24-h SBP target range defined as 110-140 mmHg was calculated with linear interpolation. Among 5152 participants included in the analysis, 186 (3.61%) cases of incident HF occurred during a median follow-up of 6.96 years. Compared with participants with SBP TTR of 0 to <25%, those with TTR of 75% to 100% had 47% lower risk of HF (hazard ratio [HR], 0.53; 95% confidence interval [CI], 0.32-0.89). The restricted spline curve depicted an inverse relationship between SBP TTR and incident HF. Additionally, the addition of SBP TTR, rather than mean SBP and SBP variation, to a conventional risk model had an incremental effect on the predictive value for HF, with integrated discrimination improvement value of 0.31% (P = 0.0003) and category-free net reclassification improvement value of 19.79% (P = 0.0081). Higher SBP TTR was associated with a lower risk of incident HF. Efforts to attain SBP within 110 to 140 mmHg may be an effective strategy to prevent HF.
RESUMEN
BACKGROUND: The Chinese visceral adiposity index (CVAI) is a new index to evaluate visceral adipose tissue in the Chinese population. Arterial stiffness (AS) is a kind of degeneration of the large arteries, and obesity is an essential contributing factor to AS. Our study aimed to explore the longitudinal association between CVAI and the risk of AS and to compare the predictive power of CVAI, body mass index (BMI), and waist circumference (WC) for AS. METHODS: Between 2010 and 2020, a total of 14,877 participants participating in at least two brachial-ankle pulse wave velocity (baPWV) measurements from the Kailuan study were included. The Cox proportional hazard regression models were performed to evaluate the longitudinal association between CVAI and the risk of AS. The area under the receiver operating characteristic (ROC) curve was calculated to compare the predictive power of CVAI, BMI, and WC for AS. RESULTS: After adjusting for potential confounding factors, CVAI was significantly associated with the risk of AS. Compared with the first CVAI quartile, the hazard ratios (HR) and 95% CI of the second, third, and fourth quartiles were 1.30 (1.09-1.56), 1.37 (1.15-1.63), and 1.49 (1.24-1.78), respectively. The area under ROC curve of CVAI was 0.661, significantly higher than BMI (AUC: 0.582) and WC (AUC: 0.606). CONCLUSION: CVAI may be a reliable indicator to identify high-risk groups of AS in the Chinese general population, and the predictive power of CVAI for AS was better than BMI and WC.
RESUMEN
INTRODUCTION: Non-alcohol fatty liver disease (NAFLD) has emerged as a public health issue, while no drugs have been specifically approved for treatment. This study aimed to examine the association between statin use and NAFLD occurrence, progression, and regression. METHODS: A cohort study was designed based on the Kailuan Study and electronic medical records (EMRs) from the Kailuan General Hospital. Participants aged 18 years with statin indication, including statin and non-statin users, were enrolled in 2010-2017. Propensity score-matched cohorts were also used. RESULTS: In the entire cohort, 21 229 non-NAFLD and 22 419 NAFLD patients (including 12 818 mild NAFLD) were included in the final analysis. After a median follow-up of about four years, the incidence of NAFLD occurrence and progression for statin users were lower than those for non-statin users (occurrence: 84.7 vs. 106.5/1000 person-years; progression: 60.7 vs. 75.5/1000 person-years). Compared with non-statin users, the risk of NAFLD occurrence (hazard ratio [HR]: 0.78, 95% confidence interval [CI]: 0.70-0.87) and regression (HR [95%CI], 0.71[0.60-0.84]) was decreased in statin users. The significantly negative association was only observed in those with cumulative statin duration ≥ 2 years (HR [95%CI] for occurrence 0.56 [0.46-0.69] vs. 0.52 [0.30-0.90] for progression) and those with low or moderate ASCVD-risk (HR [95%CI] for occurrence 0.74 [0.66-0.82] vs. 0.68 [0.57-0.80] for progression). No significant correlation was observed between statin use, statin use duration, and NAFLD regression. The PS-matched cohort had similar results. CONCLUSION: Taking statin may decrease the risk of NAFLD occurrence and progression in the population with statin indication, suggesting the potential role of statin in both primary and secondary prevention strategies for NAFLD, especially among those with low or moderate ASCVD risk.
RESUMEN
Background: Previous studies on the direction of the association between arterial stiffness (AS) and chronic kidney disease (CKD) were inconsistent, leaving a knowledge gap in understanding the temporal sequence of the association. Objectives: This study sought to assess the temporal and longitudinal relationship between AS and CKD. Methods: The temporal relationship between AS measured by brachial ankle pulse wave velocity and CKD measured by estimated glomerular filtration rate (eGFR) was analyzed among 7,753 participants with repeated examinations in the Kailuan study using cross-lagged panel analysis. The longitudinal associations of AS status and vascular aging (VA) phenotype with incident CKD were analyzed among 10,535 participants. Results: The adjusted cross-lagged path coefficient (ß 1 = -0.03; 95% CI: -0.06 to -0.01; P < 0.0001) from baseline brachial ankle pulse wave velocity to follow-up eGFR was significantly greater than the path coefficient (ß 2 = -0.01; 95% CI: -0.02 to 0.01; P = 0.6202) from baseline eGFR to follow-up brachial ankle pulse wave velocity (P < 0.0001 for the difference). During a median follow-up of 8.48 years, 953 cases of incident CKD (9.05%) occurred. After adjustment for confounders, borderline (HR: 1.17; 95% CI: 1.08-1.38) and elevated AS (HR: 1.39; 95% CI: 1.12-1.72) was associated a higher risk of CKD, compared with normal AS. Consistently, supernormal VA (HR: 0.76; 95% CI: 0.66-0.86) was associated with a decreased and early VA (HR: 1.36; 95% CI: 1.29-1.43) was associated with an increased risk of CKD, compared with normal VA. Conclusions: AS appeared to precede the decrease in eGFR. Additionally, increased AS and early VA were associated with an increased risk of incident CKD.
RESUMEN
Background: Evidence regarding the potential health effects of Life's Essential 8 (LE8) score among individuals with type 2 diabetes (T2D) is limited. Objectives: The purpose of this study was to examine the associations of LE8 score with risk of cardiovascular disease (CVD) and mortality among individuals with T2D. Methods: We prospectively followed 19,915 Chinese participants with T2D at baseline or diagnosed during follow-up (Kailuan Study: 2006-2020), who were free of CVD at diagnosis of diabetes. Diet, lifestyle, and health conditions were repeatedly assessed every 2 years. The LE8 score (range 0-100), was calculated based on 8 components: diet quality, physical activity, smoking status, sleep health, body mass index, blood lipids, blood glucose, and blood pressure. We used time-varying cox models to model the associations. Results: During a median follow-up of 11.5 years in participants with T2D, there were 3,295 incident CVD cases and 3,123 deaths. Higher LE8 score was associated with lower risk of CVD incidence and total mortality among participants with diabetes. The multivariate-adjusted HRs for the highest quintile of LE8 score compared with the lowest quintile were 0.56 (95% CI: 0.53-0.59) for CVD, 0.57 (95% CI: 0.53-0.62) for heart disease, 0.53 (95% CI: 0.49-0.57) for stroke, and 0.73 (95% CI: 0.69-0.78) for total mortality (all P trend <0.001). Furthermore, compared with participants with stable or decreased LE8 score after diabetes diagnosis, those with increased LE8 score had 17% to 42% lower risk of CVD, heart disease, stroke, and mortality. Conclusions: A higher LE8 score was associated with a substantially lower risk of CVD incidence and total mortality among adults with T2D.
RESUMEN
Background: Taste and olfactory dysfunction are commonly associated with neurodegenerative diseases and cardiovascular risk factors, but their specific associations with stroke risk remain uncertain. Objectives: The purpose of this paper was to explore whether perceived taste and olfactory dysfunctions were associated with stroke risk. Methods: Included were 85,656 participants (mean age 51.0 ± 15.3 years) of the Kailuan study. Perceived olfactory and taste dysfunctions were assessed via a questionnaire at baseline (in 2014-2016). Incident stroke cases were confirmed by review of medical records. Cox proportional hazards models were used to investigate associations of perceived olfactory and taste dysfunctions with stroke risk, and mediation analysis was used to estimate the mediating effect of chronic disease statuses. Results: We documented 2,198 incident stroke cases during a mean of 5.6 years of follow-up. Perceived taste dysfunction was associated with a doubled risk of developing total stroke (adjusted HR: 2.03; 95% CI: 1.36-3.04; P < 0.001) even with adjustment of lifestyle factors, biomarkers (ie, blood lipids, blood glucose, blood pressure, and uric acid), and other potential confounders. However, perceived olfactory dysfunction (adjusted HR: 1.22; 95% CI: 0.79-1.90; P = 0.34) was not significantly associated with a high risk of total stroke. Similar results of both perceived taste and olfactory dysfunctions were observed for ischemic stroke. Presence of chronic diseases, including hypertension, diabetes, chronic kidney disease, and overweight/obesity, mediated 4% to 5% of the association of perceived taste dysfunction with both total stroke and ischemic stroke. Conclusions: In this large cohort study, perceived taste dysfunction was associated with a high risk of developing stroke.
RESUMEN
BACKGROUND AND AIMS: Risk factor modification may decrease the risk of cardiovascular disease (CVD). Whether risk factor modification can mitigate the effect of hyperuricemia on CVD is unclear. This study aimed to investigate the risk of CVD among individuals with hyperuricemia, according to risk factors on target, compared with controls without hyperuricemia. METHODS AND RESULTS: This prospective study included 91,722 participants free of CVD at baseline (2006-2007) of the Kailuan study. Individuals with hyperuricemia were categorized according to the number of seven selected risk factors within the guideline-recommended target range (nonsmoking, physical activity, healthy diet, guideline-recommended levels of body mass index, blood pressure, fasting blood glucose, and total cholesterol). During a median follow-up of 13.00 years, 671 out of 6740 individuals (9.96%) with hyperuricemia and 6301 out of 84,982 control subjects (7.41%) had incident CVD. Compared with control subjects without hyperuricemia, individuals with hyperuricemia who had 4 or 5 to 7 risk factors on target had no significant excess CVD risk, the hazard ratio (HR) (95% confidence internal [CI]) was 0.93 (0.79-1.10) and 0.88 (0.71-1.10), respectively. Among individuals with hyperuricemia, excess CVD risk decreased stepwise for a higher number of risk factors on target, the HR of CVD associated with per additional risk factor within target range was 0.82 (95% CI, 0.77-0.87). Similar results were yielded for CVD subtypes. CONCLUSIONS: Among individuals with hyperuricemia, excess CVD risk decreased stepwise for a higher number of risk factors within target.
RESUMEN
BACKGROUND: A high triglyceride-glucose index (TyG) is associated with a higher risk of incident heart failure. However, the effects of longitudinal patterns of TyG index on the risk of heart failure remain to be characterized. Therefore, in the present study, we aimed to characterize the relationship between the trajectory of TyG index and the risk of heart failure. METHODS: We performed a prospective study of 56,149 participants in the Kailuan study who attended three consecutive surveys in 2006-2007, 2008-2009, and 2010-2011 and had no history of heart failure or cancer before the third wave survey (2010-2011). The TyG index was calculated as ln [fasting triglycerides (mg/dL) × fasting plasma glucose (mg/dL)/2], and we used latent mixture modeling to characterize the trajectory of the TyG index over the period 2006-2010. Additionally, Cox proportional risk models were used to calculate the hazard ratio (HR) and 95% confidence interval (CI) for incident heart failure for the various TyG index trajectory groups. RESULTS: From 2006 to 2010, four different TyG trajectories were identified: low-stable (n = 13,554; range, 7.98-8.07), moderate low-stable (n = 29,435; range, 8.60-8.65), moderate high-stable (n = 11,262; range, 9.31-9.30), and elevated-stable (n = 1,898; range, 10.04-10.25). A total of 1,312 new heart failure events occurred during a median follow-up period of 10.04 years. After adjustment for potential confounders, the hazard ratios (HRs) and 95% confidence intervals (CIs) for incident heart failure for the elevated-stable, moderate high-stable, and moderate low-stable groups were 1.55 (1.15, 2.08), 1.32 (1.08, 1.60), and 1.17 (0.99, 1.37), respectively, compared to the low-stable group. CONCLUSIONS: Higher TyG index trajectories were associated with a higher risk of heart failure. This suggests that monitoring TyG index trajectory may help identify individuals at high risk for heart failure and highlights the importance of early control of blood glucose and lipids for the prevention of heart failure.

BACKGROUND: The oscillometrically measured ankle-brachial index (omABI), which is determined by the ratio of ankle to brachial systolic blood pressure measured through oscillography, has been demonstrated as a robust predictor of cardiovascular events. However, the reliability of mean arterial pressure measured by oscillography may be higher than that of systolic blood pressure based on the principle of oscillographic oscillation. We aimed to compare the predictive value of oscillometrically measured ankle-tobrachial mean arterial pressure ratio (omMAPR) and omABI for cardiovascular events and all-cause mortality. METHODS: The observation cohort consisted of a total of 37 803 employees from the Chinese Kailuan Group who underwent limb blood pressure measurements during their participation in physical examination between 2010 and 2017. RESULTS: After an average follow-up period of 3 years, a total of 589 cardiovascular events and 570 cases of all-cause mortality were observed. The predictive performance of omMAPR was found to be slightly superior to omABI in terms of cardiovascular events (C-statistics: 0.55 vs. 0.51, P < .001) and all-cause mortality (C-statistics: 0.60 vs. 0.55, P <.001). After adjusting for confounders, within a specific range (omMAPR ≤ 1.06 or omABI ≤ 1.12), each 0.1-unit increase in omMAPR was associated with reductions of 14% (HR = 0.86, 95% CI: 0.77-0.96) and 23% (HR = 0.77, 95% CI: 0.70-0.84) in cardiovascular events and all cause mortality, respectively, while each 0.1-unit increase in omABI was associated with reductions of 12% (HR = 0.88, 95% CI: 0.79-0.97) and 22% (HR = 0.78, 95% CI: 0.72-0.85) in cardiovascular events and all-cause mortality, respectively. However, once out of that range (omMAPR > 1.06 or omABI > 1.12), neither omMAPR nor omABI was significantly associated with cardiovascular events or all-cause mortality. CONCLUSION: Both omMAPR and omABI within specific ranges (omMAPR ≤ 1.06 or omABI ≤ 1.12) were independent predictors for cardiovascular events and all-cause mortality. Moreover, omMAPR exhibited a slightly superior predictive ability compared to omABI in relation to cardiovascular events and all-cause mortality. The trial registration number is ChiCTR-TNRC-11001489.
RESUMEN
BACKGROUND: Emerging evidence suggests a central role for inflammation in cardiac conduction disorder (CCD). It is unknown whether habitual physical activity could modulate the inflammation-associated risks of incident CCD in the general population. METHODS AND RESULTS: This population-based cohort was derived from the China Kailuan study, including a total of 97 192 participants without prior CCD. The end points included incident CCD and its subcategories (atrioventricular block and bundle-branch block). Systemic inflammation was indicated by the monocyte-to-lymphocyte ratio (MLR). Over a median 10.91-year follow-up, 3747 cases of CCD occurred, with 1062 cases of atrioventricular block and 2697 cases of bundle-branch block. An overall linear dose-dependent relationship was observed between MLR and each study end point (all P-nonlinearity≥0.05). Both higher MLR and physical inactivity were significantly associated with higher risks of conduction block. The MLR-associated risks of developing study end points were higher in the physically inactive individuals than in those being physically active, with significant interactions between MLR levels and physical activity for developing CCD (P-interaction=0.07) and bundle-branch block (P-interaction<0.05) found. Compared with those in MLR quartile 2 and being physically active, those in the highest MLR quartile and being physically inactive had significantly higher risks for all study end points (1.42 [95% CI, 1.24-1.63], 1.62 [95% CI, 1.25-2.10], and 1.33 [95% CI, 1.13-1.56], respectively, for incident CCD, atrioventricular block, and bundle-branch block). CONCLUSIONS: MLR should be a biomarker for the risk assessment of incident CCD. Adherence to habitual physical activity is favorable for reducing the MLR-associated risks of CCD.

OBJECTIVE: This study explored the mediating effect of diabetes on the relationship between nonalcoholic fatty liver disease (NAFLD) and atherosclerotic cardiovascular disease (ASCVD). METHODS: In this prospective community cohort study, 82 975 participants were enrolled, with the primary outcome being the incidence of new-onset ASCVD. Using the Cox proportional hazards model, the hazard ratio (HR) and 95% confidence interval (CI) for ASCVD occurrence were computed between NAFLD and non-NAFLD groups. The correlation between NAFLD and diabetes was assessed using a binary logistic regression model, and that between NAFLD, diabetes and ASCVD using a mediation model. RESULTS: During follow-up, 9471 ASCVD cases were observed. Compared with individuals without NAFLD, those with NAFLD showed an increased ASCVD risk (HR: 1.424; 95% CI: 1.363-1.488; Pâ <â 0.001). Stratifying NAFLD based on metabolic subphenotypes revealed a higher ASCVD risk in the NAFLD combined with diabetes subgroup than in the non-NAFLD subgroup (HR: 1.960; 95% CI: 1.817-2.115; Pâ <â 0.001). NAFLD was positively associated with baseline diabetes (odds ratio: 2.983; 95% CI: 2.813-3.163; Pâ <â 0.001). Furthermore, NAFLD severity was positively correlated with diabetes risk. Mediation analysis indicated that diabetes partially mediated the effect of NAFLD on ASCVD incidence, accounting for 20.33% of the total effect. CONCLUSION: NAFLD is an independent predictor of increased ASCVD risk, which may be slightly mediated by diabetes in patients with NAFLD. Evaluating NAFLD and diabetes may be crucial in the early screening and prevention of ASCVD.

Background: Sleep complaints were reported to be associated with stroke, however, the evidence on the association between healthy sleep pattern and stroke risk in Chinese is limited. Objective: The aim of this study was to investigate the association between healthy sleep pattern and stroke in Chinese, and the influence of metabolic diseases on the association. Methods: A total of 11,851 participants from the Kailuan study in China without stroke at baseline were included. We calculated a healthy sleep score according to four sleep factors, and defined the low-risk groups as follows: no insomnia, no excessive daytime sleepiness, no frequent snoring, and sleep 7-8h/d. Each low-risk sleep factor was assigned a score of 1. Cox proportional hazard models were used to assess the association between healthy sleep score and stroke. Mediation analysis was used to estimate the role of metabolic diseases (obesity, diabetes, and hypertension) in the healthy sleep score-stroke association. Results: During a mean follow-up period of 7.7 years, 504 cases of stroke were identified. A higher healthy sleep score was associated with a lower risk of stroke in a dose-response manner (P-trend=0.03). The adjusted hazard ratio (HR) for participants with a healthy sleep score of 4 versus ≤2 was 0.75 (95% confidence interval [CI]: 0.56, 0.96). In addition, obesity, diabetes, and hypertension collectively explained 21.9% (95% CI: 17.2, 26.5) of the association between healthy sleep score and stroke. Conclusion: Adherence to healthy sleep pattern was associated with a lower risk of stroke, and the favorable association was partially mediated by metabolic diseases.
RESUMEN
Introduction: The association between the longitudinal patterns of estimated glomerular filtration rate (eGFR) and risk of atrial fibrillation (AF) in populations with normal or mildly impaired renal function is not well characterized. We sought to explore the eGFR trajectories in populations with normal or mildly impaired renal function and their association with AF. Methods: This prospective cohort study included 62,407 participants who were free of AF, cardiovascular diseases, and moderate to severe renal insufficiency (eGFR <60 mL/min/1.73 m2) before 2010. The eGFR trajectories were developed using latent mixture modeling based on examination data in 2006, 2008, and 2010. Incident AF cases were identified in biennial electrocardiogram assessment and a review of medical insurance data and discharge registers. We used Cox regression models to estimate the hazard ratios and 95% confidence intervals (CIs) for incident AF. Results: According to survey results for the range and changing pattern of eGFR during 2006-2010, four trajectories were identified: high-stable (range, 107.47-110.25 mL/min/1.73 m2; n = 11,719), moderate-increasing (median increase from 83.83 to 100.37 mL/min/1.73 m2; n = 22,634), high-decreasing (median decrease from 101.72 to 89.10 mL/min/1.73 m2; n = 7,943), and low-stable (range, 73.48-76.78 mL/min/1.73 m2; n = 20,111). After an average follow-up of 9.63 years, a total of 485 cases of AF were identified. Compared with the high-stable trajectory, the adjusted hazard ratios of AF were 1.70 (95% CI, 1.09-2.66) for the moderate-increasing trajectory, 1.92 (95% CI, 1.18-3.13) for the high-decreasing trajectory, and 2.28 (95% CI, 1.46-3.56) for the low-stable trajectory. The results remained consistent across a number of sensitivity analyses. Conclusion: The trajectories of eGFR were associated with subsequent AF risk in populations with normal or mildly impaired renal function.
The relation between estimated glomerular filtration rate (eGFR) within the normal or mildly impaired range and risk of atrial fibrillation (AF) in former studies is controversial, and data on longitudinal pattern of eGFR in such topic is sparse. In this cohort study, we identified 4 trajectories of eGFR in populations with normal or mildly impaired renal function. Relative to populations with high-stable pattern of eGFR, those with low-stable pattern, high-decreasing pattern and moderate-increasing pattern were associated with 128%, 92%, and 70% higher risk of AF, respectively. These findings suggested that monitoring eGFR trajectories is an important approach for AF prediction in populations with normal or mildly impaired renal function. Decreasing and consistently low eGFR trajectories within the currently designated normal or mildly impaired range may still significantly increase the risk of AF.
RESUMEN
Background: Rheumatoid arthritis (RA) is a systemic and chronic autoimmune disease that is characterized by persistent joint inflammation. RA patients experience a considerably increased risk of cardiovascular-related morbidity and mortality. The current study investigated the association between triglyceride glucose (TyG) index and major adverse cardiovascular events (MACEs) in a predominantly male cohort of RA patients. Methods: A total of 1613 RA patients (81.53% male) were selected from the Kailuan study. The TyG index was calculated as the logarithmic product of fasting blood triglyceride and fasting blood glucose divided by two. MACEs were defined as the composite of non-fatal myocardial infarctions and non-fatal strokes. Cox proportional hazards analysis was performed to study the association between the TyG index and MACEs. Results: A total of 59 MACEs occurred during the median follow-up time of 5.32 years. Following adjustment for age and gender, analysis by multivariable Cox proportional hazards (model 1) showed that an elevated TyG index was associated with an increased risk of MACEs (quartile 2, hazard ratio (HR): 2.741, 95% confidence interval (CI): 1.220-6.157, p = 0.015; quartile 4, HR: 2.521, 95% CI: 1.074-5.917, p = 0.034). After adjustment for other variables, Cox proportional hazards analysis (model 2) showed that an elevated TyG index was independently associated with an increased risk of MACEs (quartile 2, HR: 2.348, 95% CI: 1.009-5.465, p = 0.048). In addition, subgroup analysis showed a higher TyG index was significantly linked to an increased risk of MACEs in patients aged more than 65 years (quartile 2, HR: 6.048, 95% CI: 1.311-27.908, p = 0.021; quartile 4, HR: 12.074, 95% CI: 1.438-101.358, p = 0.022). Conclusions: The TyG index was associated with an increased risk of MACEs in a predominantly male cohort of RA patients. This index may be helpful for the prediction of MACEs in male patients with RA. Clinical Trial Registration: Registration number in the Chinese clinical trial registry: ChiCTR-TNRC-11001489.
RESUMEN
BACKGROUND: Cardiovascular disease (CVD) is a chronic disease with a serious prognosis, and obesity is a risk factor for CVD. Lipid accumulation product index (LAP) is a new indicator of obesity, waist circumference, and triglycerides were included in the formula, but its association with CVD is inconsistent. Therefore, this study researched the effect of LAP levels on CVD. METHODS: This prospective cohort study was based on the Kailuan cohort. A total of 95,981 participants who completed the first physical examination in 2006 and had no history of CVD or LAP absence were included. The participants were divided into four groups according to the LAP quartile (Q1 - Q4). Up until December 31, 2022, incidence density was calculated for each group. The hazard ratio (HR) and 95% confidence interval (CI) of CVD in each group were calculated by the Cox proportional hazards model. RESULTS: During a median follow-up period of 15.95 years, 9925 incident CVD events occurred (2123 myocardial infarction and 8096 stroke). There were differences in potential confounders among the four groups (P < 0.001). The incidence density and 95% CI of CVD in Q1-Q4 groups were 4.76(4.54, 5.00), 6 0.50(6.24, 6.77), 8.13(7.84, 8.44) and 9.34(9.02, 9.67), respectively. There were significant differences in the survival curves among the four groups by log-rank test (P < 0.001). After adjusting for potential confounders, Cox proportional hazards model results showed that compared with the Q1 group, the HR and 95% CI of CVD in the Q2, Q3, and Q4 groups were1.15(1.08, 1.23), 1.29(1.21, 1.38) and 1.39(1.30, 1.49), respectively. The HR and 95%CI of myocardial infarction were 1.28(1.10, 1.49), 1.71(1.47, 1.98) and 1.92(1.64, 2.23), respectively. The HR and 95%CI of stroke were 1.11 (1.03, 1.19), 1.20 (1.12, 1.29) and 1.28 (1.19, 1.38), respectively. After subgroup analysis by gender, there was no significant interaction (P = 0.169), and the relationship between LAP and CVD in different genders was consistent with the main results. After subgroup analysis by age, there was a significant interaction (P = 0.007), and the association between LAP and CVD in different age groups was consistent with the main results. After subgroup analysis by BMI, there was no significant interaction (P = 0.506), and the association between LAP and CVD in different BMI groups was consistent with the main results. The results remained robust after sensitivity analyses. For each unit increase in ln(LAP), the HR and 95%CI of CVD were 4.07 (3.92, 4.23). CONCLUSION: This study demonstrated that the risk of CVD increased with the increase of LAP level. The risk of CVD in group Q2 - Q4 was 1.15, 1.29, and 1.39 times higher than that in group Q1, respectively. CLINICAL TRIAL REGISTRATION NUMBER: ChiCTR2000029767.
RESUMEN
The present study aimed to assess the risk of postmenopausal breast cancer in women based on a combination of body mass index (BMI) and high-sensitivity C-reactive protein (hs-CRP) levels. A total of 20,400 participants were investigated as part of the 'Kailuan Study' clinical trial. Participants were classified into four groups based on BMI (BMI ≥24 or <24 kg/m2) and hs-CRP level (hs-CRP ≥3 or <3 mg/l). Cox proportional hazards models were used to evaluate the association between the combination of BMI and hs-CRP and the risk of postmenopausal breast cancer. A total of 19,540 participants met the inclusion criteria. The median follow-up time was 14.97 years, with a cumulative follow-up period of 283,599.43 person-years. Among the participants, 269 individuals were diagnosed with postmenopausal breast cancer. Individuals with a high BMI (BMI ≥24 kg/m2) and a high hs-CRP level (hs-CRP ≥3 mg/) had a greater risk of postmenopausal breast cancer compared with individuals with a low BMI (BMI <24 kg/m2) and a low hs-CRP level (<3 mg/l) (hazard ratio, 1.75; 95% confidence interval, 1.25-2.47). The sensitivity analysis showed findings consistent with the primary results. In conclusion, the combination of high BMI and high hs-CRP level is associated with an increased risk of postmenopausal breast cancer. The present study is part of the Kailuan Study.

RESUMEN
Background: Diet quality significantly influences aging processes and age-related health outcomes. This study aims to explore the association between dietary quality and accelerated aging in two large cohorts. Methods: This study collected data from the Kailuan and National Health and Nutrition Examination Survey (NHANES) cohorts; participants' dietary quality was evaluated using the American Heart Association (AHA) dietary score and Healthy Eating Index-2015 (HEI-2015), respectively. Accelerated aging in participants was determined by calculating the difference between phenotypic age and chronological age. Logistic regression models were used to explore the association between dietary quality scores and accelerated aging. Additionally, variations in this association across different subgroups were investigated. To minimize the influence of excessive aging, individuals aged 75 and above were excluded in sensitivity analyses. Results: In this study, we included 33 701 participants (27.3% female, mean age 57.29 ± 11.88) from the Kailuan study and 9285 participants (50.6% female, mean age 49.83 ± 17.62) from NHANES. In the Kailuan cohort, individuals with dietary scores ranging from 3 to 5 exhibited a 22% lower risk of accelerated aging compared to those scoring between 0 and 2 (OR = 0.78, 95% CI = 0.72-0.85). Similarly, in the NHANES cohort, participants in the highest quartile of HEI-2015 experienced a 34% reduction in the risk of accelerated aging compared to those in the lowest quartile (OR = 0.66, 95% CI = 0.52-0.84). Subgroup analyses underscored a more pronounced association between dietary quality and accelerated aging among males and individuals with unhealthy lifestyles. Sensitivity analyses confirmed the robustness of the association between dietary quality and accelerated aging. Conclusion: In summary, our study found a significant association between dietary quality and accelerated aging. Better dietary quality was associated with a reduced risk of accelerated aging, particularly among males, smokers, and participants with unhealthy lifestyles.
