Background and aimsThere is still inconsistent evidence over the protective effect of total bilirubin on the development of coronary heart disease (CHD). Therefore, we aimed to investigate the association between bilirubin in population subtypes and the risks of CHD between different gender and menstruation subgroups.Methods and resultsIn this prospective cohort study, 29,750 participants free of CHD with an average age of 47 ± 14 years were recruited at baseline; of these, 720 CHD first-attack cases were collected after 7-years of follow up. The covariate-adjusted Cox proportional hazards models were used to estimate hazard ratios (HRs) of CHD with 95% confidence intervals (CIs). The serum bilirubin concentration was quarterly stratified based on the distribution of healthy population without CHD onset. The HRs of incident CHD decreased with elevated bilirubin in females (ρ trend<0.05), but not males. In postmenopausal females, compared with the lowest quartile of total bilirubin, the adjusted HRs for the third and fourth quartiles were 0.64 (95% CI: 0.45, 0.93) and 0.59 (95% CI: 0.42, 0.86), the adjusted HRs in the third and fourth quartiles of direct bilirubin were 0.56 (0.39, 0.82) and 0.56 (0.38, 0.81), and for indirect bilirubin, corresponding HR in the highest quartile was 0.56 (0.38, 0.83).ConclusionElevated serum bilirubin was inversely associated with adjusted HRs of CHD in females, especially postmenopausal females. The relationship between elevated direct bilirubin and reduced HRs of CHD may be closer than indirect bilirubin in postmenopausal females. 相似文献
Background and aimsIt is recognized that malnutrition increases risk of worse prognosis in patients with various diseases. The present study investigated if poor nutritional status predicts adverse outcomes in patients with non-ST-segment elevation acute coronary syndrome (NSTE-ACS) undergoing percutaneous coronary intervention (PCI).Methods and resultsThe study enrolled 2299 patients (mean age: 60.01 ± 8.95 years; 71.8% male) with NSTE-ACS who underwent PCI at Beijing Anzhen Hospital from January to December 2015. The entire cohort was divided into training set (n = 1519) and testing set (n = 780) at a ratio of approximate 2 : 1. Nutritional status was assessed by geriatric nutritional risk index (GNRI). The primary endpoint was a composite of adverse events as follows: all-cause death, non-fatal myocardial infarction (MI) and any revascularization. Multivariate Cox analysis showed that GNRI significantly associated with primary endpoint, independent of other risk factors [hazard ratio (HR) 1.159 per 1-point decrease of GNRI, 95% confidence interval (CI) 1.130–1.189, p < 0.001]. The addition of GNRI to a baseline model had an incremental effect on the predictive value for adverse prognosis in training set [AUC: from 0.821 to 0.873, p < 0.001; category-free net reclassification improvement (NRI): 0.313, p < 0.001; integrated discrimination improvement (IDI): 0.108, p < 0.001]. The incremental effect of GNRI was further validated and confirmed in testing set.ConclusionLower GNRI is a significant predictor of adverse prognosis in patients with NSTE-ACS undergoing PCI. Further studies need to be performed to determine whether nutritional interventions have a positive impact on improving clinical prognosis. 相似文献
Background and aimsThis study aimed to assess possible association of detailed abdominal fat profiles with coronary plaque characteristics in patients with acute coronary syndrome (ACS).Methods and resultsIn 60 patients with ACS, culprit arteries were evaluated at 1-mm intervals (length analyzed: 66 ± 28 mm) by grayscale and integrated backscatter intravascular ultrasound (IB-IVUS) before percutaneous coronary intervention. Standard IVUS indexes (as a volume index: volume/length), plaque components (as percent tissue volume) and fibrous cap thickness (FCT) were assessed by IB-IVUS. Plain abdominal computed tomography was performed to evaluate subcutaneous adipose tissue (SAT) area, visceral adipose tissue (VAT) area, and VAT/SAT ratio. While SAT area only correlated with vessel volume (r = 0.27, p = 0.04), VAT area correlated positively with vessel (r = 0.30, p = 0.02) and plaque (r = 0.33, p = 0.01) volumes and negatively with FCT (r = −0.26, p = 0.049), but not with percent plaque volume and plaque tissue components. In contrast, higher VAT/SAT ratio significantly correlated with higher percent lipid (r = 0.34, p = 0.008) and lower percent fibrous (r = −0.34, p = 0.007) volumes with a trend toward larger percent plaque volume (r = 0.19, p = 0.15), as well as thinner FCT (r = −0.53, p < 0.0001). In the multiple regression analysis, higher VAT/SAT ratio was independently associated with higher percent lipid with lower percent fibrous volumes (p = 0.03 for both) and thinner fibrous cap thickness (p = 0.0001).ConclusionCoronary plaque vulnerability, defined as increased lipid content with thinner fibrous cap thickness, appears to be more related to abnormal abdominal fat distribution, or so-called hidden obesity, compared with visceral or subcutaneous fat amount alone in patients with ACS. 相似文献
Background and aimsResearch suggests that meat intake may increase the risk of coronary heart disease (CHD), but most studies take place in Western countries, where the types and amount of meat products consumed differ from those in Asian countries. We aimed to identify the association between meat intake and CHD risk in Korean male adults, using the Framingham risk score.Methods and resultsWe used data from the Korean Genome and Epidemiology Study (KoGES) Health Examinees (HEXA) study, including 13,293 Korean male adults. We estimated the association of meat intake with ≥20% 10-year CHD risk using Cox proportional hazards regression models to calculate the hazard ratios (HRs) and 95% confidence intervals (CIs). Subjects with the highest total meat intake had a 53% (model 4: HR 1.53, 95% CI 1.05–2.21) increased 10-year CHD risk compared to those with the lowest intake. Those with the highest red meat intake had a 55% (model 3: HR 1.55, 95% CI 1.16–2.06) increased 10-year CHD risk compared to those with the lowest intake. No association was observed between poultry or processed meat intake and 10-year CHD risk.ConclusionsConsumption of total meat and red meat was associated with a higher risk of CHD in Korean male adults. Further studies are needed to provide criteria for the appropriate meat intake by meat type to reduce CHD risk. 相似文献
AimsCirculating vitamin D is linked with the risk of cardiovascular disease (CVD). A meta-analysis has yet to explicitly explore correlation between vitamin D and the risk of CVD incidence and recurrent CVD. This meta-analysis examines the association between 25-hydroxy-vitamin D (25(OH)D) and the risk of CVD incidence (fatal, non-fatal, fatal and non-fatal combined events) and the risk of recurrent CVD (fatal, recurrent, and fatal and recurrent combined events). PROSPERO registration-CRD42021251483.Data synthesisA total of 79 studies (46 713 CVD cases in 1 397 831 participants) were included in the meta-analysis, of which 61 studies examined the risk of CVD incidence events, and 18 studies examined risk of recurrent CVD events. The risk of CVD incidence events (RR = 1.34, 95% CI: 1.26–1.43, p < 0.001) and recurrent CVD events (RR = 1.86, 95% CI: 1.46–2.36, p < 0.001) was higher in the lowest than the highest category of circulating 25(OH)D. Dose–response analysis reported a linear association for every 10 ng/ml increment of 25(OH)D and non-fatal CVD incidence events (RR = 0.94; 95% CI = 0.89–0.98, p = 0.005), lower fatal recurrent CVD events (RR = 0.45; 95% CI = 0.32–0.62, p < 0.001) and lower combined recurrent CVD events (RR = 0.80; 95% CI = 0.65–0.97, p = 0.023). A non-linear association was observed between higher 25(OH)D and lower fatal CVD incidence events (P-nonlinear<0.001), lower combined CVD incidence events (P-nonlinear = 0.001), and lower non-fatal recurrent CVD events (P-nonlinear = 0.044).ConclusionsThe lowest category of circulating 25(OH)D was associated with a higher risk of CVD incidence events and recurrent CVD events. 相似文献
Background and aimsAlthough high serum uric acid (SUA) at baseline has been linked to increased risk for metabolic syndrome (MetS), the association of longitudinal SUA changes with MetS risk is unclear. We aimed to examine the effect of distinct SUA trajectories on new-onset MetS risk by sex in a Chinese cohort.Methods and resultsA total of 2364 women and 2770 men who were free of MetS in 2013 were enrolled in this study and followed up to 2018. Group-based trajectory modeling was applied to identify SUA trajectories. Cox proportional hazards model was used to evaluate the association between SUA trajectory and new-onset MetS. The dose–response relationship between SUA trajectories and MetS risk was examined by treating trajectory groups as a continuous variable. During a median follow-up of 48.0 months, 311 (13.16%) women and 950 (34.30%) men developed MetS. SUA trajectories (2013–2018) were defined as four distinct patterns in both women and men: “low”, “moderate”, “moderate-high”, and “high”. Compared with “low” SUA trajectory, the adjusted hazard ratio for incident MetS among participants with “moderate”, “moderate-high” and “high” trajectory was in a dose–response manner: 1.75 (95% CI: 1.08–2.82), 1.94 (95% CI: 1.20–3.14), and 3.05 (95% CI: 1.81–5.13), respectively, for women; 1.20 (95% CI: 0.97–1.49), 1.48 (95% CI: 1.19–1.85), and 1.66 (95% CI: 1.25–2.21), respectively, for men.ConclusionsElevated SUA trajectories are associated with increased risk for new-onset MetS in women and men. Monitoring SUA trajectories may assist in identifying subpopulations at higher risk for MetS. 相似文献
AimThis study aimed to determine the association between fenofibrate added to statin therapy and diabetic retinopathy progression.MethodsIn this propensity-matched study using the Korean National Health Insurance Service cohort (2002–2019), patients with type 2 diabetes and metabolic syndrome (≥ 30 years) receiving statin therapy were matched 1:2 by propensity score into the statin plus fenofibrate group (n = 22,395) and statin-only group (n = 43,191). The primary outcome was a composite of diabetic retinopathy progression including vitreous hemorrhage, vitrectomy, laser photocoagulation, intravitreous injection therapy and retinal detachment.ResultsThe median (quartiles) follow-up duration was 44.0 (27.6–70.6) months. For the primary outcome, the incidence rate per 1,000 person-years was 9.66 in the statin-only group and 8.68 in the statin-plus-fenofibrate group. The risk of the primary outcome was significantly lower (hazard ratio [HR]=0.88; 95% confidence interval [0.81;0.96] P = 0.005) in the statin-plus-fenofibrate group than in the statin-only group. Only patients with pre-existing retinopathy showed benefits from fenofibrate treatment (HR=0.83 [0.73;0.95] P = 0.006). In addition, the statin plus fenofibrate group exhibited significantly lower risks of vitreous hemorrhage (HR= 0.86 [0.75;0.995] P = 0.042), laser photocoagulation (HR=0.86 [0.77;0.96] P = 0.009) and intravitreous injection therapy (HR=0.73 [0.59;0.90] P = 0.003) than those in the statin-only group. There was no significant interaction between the different characteristics at baseline and the treatment effect.ConclusionThe addition of fenofibrate to statins was associated with significantly lower risk of diabetic retinopathy progression than statin therapy alone in patients with type 2 diabetes and metabolic syndrome. 相似文献
Background and aimsTriglyceride-Glucose (TyG) index is an accurate biomarker of insulin resistance, which is potentially associated with adverse cardiovascular events. We aimed to assess the dose–response relationship between Triglyceride-Glucose (TyG) Index and Major Adverse Cardiovascular Events (MACE) in patients with Acute Coronary Syndrome (ACS).Methods and resultsA systematic literature search was performed using PubMed, Scopus, and Embase for records published from the inception up until 7 February 2021. Studies that fulfilled all of these criteria were included: 1) prospective or retrospective observational studies reporting patients with ACS and 2) assessing the impact of TyG index on MACE with at least three quantitative classifications. The outcome of interest is MACE across the TyG index intervals. MACE was a composite of all-cause mortality, myocardial infarction, unstable angina pectoris, target vessel revascularization, cerebrovascular accidents, and heart failure. The effect estimates were reported as relative risks (RRs). There are 13,684 subjects from 4 studies included in this meta-analysis. This meta-analysis showed that the highest category of TyG index was associated with twofold MACE (RR 2.09 [1.59, 2.76], p < 0.001; I2: 68.4%, p = 0.02) compared to the lowest category in patients with ACS. Dose–response meta-analysis showed that the relationship between TyG index and MACE was non-linear (p < 0.001), with statistical significance reached around TyG index 8.9 and increased non-linearly. The dose–response curve became significantly steeper after TyG index of 9.1–9.2.ConclusionTyG index was associated with MACE in patients with ACS in a non-linear fashion.ProsperoCRD42021235765. 相似文献
Background and aimsCesarean delivery may increase the risk of childhood obesity, a precursor of metabolic syndrome (MetS). We aimed to investigate the association of elective cesarean delivery (ElCD) with MetS and its components in a Chinese birth cohort.Methods and resultsThis cohort included 1467 children (737 delivered by ElCD and 730 by spontaneous vaginal delivery [SVD]) who were followed up at the age of 4–7 years in 2013. MetS was defined as the presence of ≥3 components: central obesity, hypertriglyceridemia, low high-density lipoprotein (HDL), high fasting glucose, and hypertension. Of the 1467 children, 93 (6.3%) were categorized as having MetS: 50 (6.8%) delivered by ElCD and 43 (5.9%) by SVD. After multivariable adjustment, ElCD was not associated with MetS (adjusted odds ratio [AOR] 1.15, 95% confidence interval [CI] 0.74, 1.78) or certain components including hypertriglyceridemia, low HDL, and high fasting glucose but was associated with central obesity (AOR 1.33, 95% CI 1.02, 1.72) and hypertension (AOR 1.50, 95% CI 1.15, 1.96), as well as higher levels of total cholesterol (3.43 vs. 3.04 mmol/L; P < 0.001), low-density lipoprotein–cholesterol (1.77 vs. 1.67 mmol/L, P = 0.002), fasting glucose (5.08 vs. 5.02 mmol/L, P = 0.022), systolic (97.57 vs. 94.69 mmHg, P < 0.001)/diastolic blood pressure (63.72 vs. 62.24 mmHg, P < 0.001), and BMI (15.46 vs. 14.83 kg/m2, P < 0.001) than SVD.ConclusionsElCD is not associated with MetS in early to middle childhood but is associated with its components including central obesity and hypertension, as well as various continuous indices. 相似文献
Background and aimsDietary intakes play important roles in the prevention and treatment of coronary heart disease (CHD). Coronary plaque vulnerability is the key mechanism leading to CHD progression. We aimed to explore the association between dietary intakes and plaque vulnerability via optical coherence tomography (OCT).Methods and resultsA total of 314 CHD patients were included in this study. Dietary intake status was assessed by semi-quantitative food frequency questionnaire and plaque vulnerability was measured by OCT. The results showed that vegetables were negatively associated with macrophage infiltration, thin cap fibroatheroma (TCFA) and thrombus [odds ratio (OR) = 0.48, 0.38, 0.38, 95% confidence interval (95% CI) = 0.24–0.93, 0.17–0.84, 0.15–0.94, all P < 0.05]; fruits were negatively associated with lipid plaque, TCFA, rupture and thrombus (OR = 0.17, 0.11, 0.12, 0.20, 95% CI = 0.07–0.39, 0.04–0.29, 0.05–0.28, 0.08–0.55, all P < 0.05); salt was positively associated with lipid plaque and TCFA (OR = 2.59, 2.83, 95% CI = 1.14–5.90, 1.23–6.51, all P < 0.05). Regarding nutrients intakes, dietary fiber was negatively associated with macrophage infiltration (OR = 0.34, 95% CI = 0.14–0.85, P = 0.021); folate was negatively associated with lipid plaque, TCFA and rupture (OR = 0.22, 0.16, 0.20, 95% CI = 0.09–0.58, 0.06–0.41, 0.08–0.51, all P < 0.05); vitamin C was negatively associated with TCFA, rupture and thrombus (OR = 0.26, 0.22, 0.05, 95% CI = 0.07–0.95, 0.07–0.65, 0.01–0.25, all P < 0.05); sodium was positively associated with lipid plaque, TCFA, rupture and thrombus (OR = 3.43, 3.96, 2.73, 4.84, 95% CI = 1.51–7.80, 1.66–9.45, 1.18–6.27, 1.76–9.28, all P < 0.05).ConclusionSalt and sodium were dietary risk factors for plaque vulnerability, whereas vegetables, fruits, dietary fiber, folate and vitamin C were dietary protective factors for plaque vulnerability. 相似文献
Background and aimsChildhood overweight and obesity are lifetime risk factors for cardiovascular disease but the relationship between dynamic body mass index (BMI) change and cardiovascular structure and function in early childhood remains unclear.Methods and resultsThis cohort study consisted 525 participants with 6 distinct representative growth patterns to examine the associations between BMI growth patterns and subsequent cardiovascular structure and function at age 4. BMIs were obtained at birth, 2 and 4 years old. Cardiovascular assessments were performed, including blood pressure (BP), cardiac geometric parameters, left ventricular (LV) function, speckle-tracking, integrated backscatter analysis and carotid intima-media thickness. Compared to the stable normal BMI pattern, children with the stable overweight (OW) pattern had significantly greater LV anatomic parameters in fully adjusted models. Children with the catch-up (CU) pattern revealed a uniform trend and had poorer strain. LV diameters and integrated backscatter signals were larger for those with BMI gain and lose pattern. Children with BMI lose pattern showed improved tendency involving LV mass index and BP. Both OW and CU patterns were associated with high systolic BP [odds ratio (95% CI): OW: 3.67 (1.08, 12.47); CU: 4.24 (1.75, 10.28)]. Compared to static BMI measurements at birth, 2 and 4 years old, dynamic BMI growth patterns were more predictive of cardiovascular structure and function at 4.ConclusionsChildren with overweight-related BMI growth patterns in early childhood experienced undesirable cardiovascular functional or structural changes as early as 4 years old, indicating that early intervention is needed and potentially beneficial. 相似文献
Background and aimsThis study aimed to review the available data on the role of coronary artery calcium (CAC) scoring as the preferred adjunct modality to improve risk prediction and reduce the incidence of major adverse cardiac events and mortality in T2DM patients.MethodsWe reviewed the findings of 21 studies.ResultsThis study revealed that the CAC scoring system could enhance cardiovascular disease (CVD) risk stratification and positively affect the medical management of patients with T2DM.ConclusionA CAC scoring approach is necessary to reduce the incidence and prevalence of preventable CVD events in patients with type 2 diabetes. 相似文献
Background and aimsThe association of the triglyceride glucose (TyG) index with carotid atherosclerosis has not been reported in longitudinal studies. The present study aimed to investigate whether the TyG index increases the risk of carotid atherosclerosis incidence.Methods and resultsThis study included data from the Beijing Health Management Cohort (BHMC; n = 6955) and the Beijing Physical Examination Cohort (BPEC; n = 8473). Participants without a history of carotid atherosclerosis who underwent health examination in 2011 or 2012 were annually followed until 2019. The TyG index was denoted as ln [triglycerides (mmol/L)1fasting glucose (mmol/L)/2]. During a median follow-up of 5.02 years and 5.36 years, 1441 individuals in the BHMC group and 2181 individuals in the BPEC group developed carotid plaque, respectively. The adjusted hazard ratios (HRs) of the continuous TyG index were 1.253 (95% CI, 1.044 to 1.505) and 1.252 (95% CI, 1.091 to 1.437) for the BHMC and BPEC groups, respectively. Individuals in the highest quartile of the TyG index were associated with an increased risk of carotid plaque compared with those in the lowest quartile (BHMC: HR, 1.366; 95% CI, 1.101 to 1.695, P for trend = 0.010; BPEC: HR, 1.379; 95% CI, 1.196 to 1.591, P for trend = 0.013).ConclusionThese findings suggested that a higher TyG index increases the risk of carotid atherosclerosis incidence in the general population. 相似文献
