Abstract
Aim To determine clinical and laboratory parameters associated with in-hospital mortality in patients with acute myocardial infarction and to develop a multifactorial prognostic model of in-hospital mortality.Material and methods This was a study based on the 2019-2020 Registry of acute coronary syndrome of the Tyumen Cardiology Research Center, a branch of the Tomsk National Research Medical Center. The study included 477 patients with ST-segment elevation acute myocardial infarction (AMI), 617 patients with non-ST segment elevation AMI, and 26 patients with unspecified AMI. In-hospital mortality was 6.0 % (n=67). Clinical and laboratory parameters were assessed on the day of admission. The separation power of indicators associated with in-hospital mortality was determined using a ROC analysis. The data array of each quantitative parameter was converted into a binary variable according to the obtained cut-off thresholds, followed by creation of a multifactorial model for predicting in-hospital mortality using a stepwise analysis with backward inclusion (Wald). The null hypothesis was rejected at p<0.05.Results The multivariate model for prediction of in-hospital mortality included age (cut-off, 72 years), OR 3.0 (95 % CI: 1.5-5.6); modified shock index (cut-off threshold, 0.87), OR 1.5 (95 % CI: 1.1-2.0); creatine phosphokinase-MB (cut-off threshold, 32.8 U / L), OR 4.1 (95 % CI: 2.2-7.7); hemoglobin (121.5 g / l), OR 1.7 (95 % CI: 1.2-2.3); leukocytes (11.5×109 / l), OR 1.9 (95 % CI: 1.3-2.6); glomerular filtration rate (60.9 ml / min), OR 1.7 (95 % CI: 1.2-2.2); left ventricular ejection fraction (42.5 %), OR 4.1 (95 % CI: 2.0-8.3); and size of myocardial asynergy (32.5 %), OR 2.6 (95 % CI: 1.4-5.0).Conclusions Independent predictors of in-hospital mortality in AMI are age, modified shock index, creatine phosphokinase-MB, peripheral blood leukocyte count, hemoglobin concentration, left ventricular ejection fraction, size of myocardial asynergy, and glomerular filtration rate. The in-hospital mortality model had a high predictive potential: AUC 0.930 (95 % CI: 0.905-0.954; p <0.001) with a cutoff threshold of 0.15; sensitivity 0.851, and specificity 0.850.

Ethnicity and sex-specific 99th percentile upper reference limits of high-sensitivity cardiac troponin I among adults in Xinjiang, China. Clin Biochem 2023; 116:94-99. [PMID: 37084997 DOI: 10.1016/j.clinbiochem.2023.04.004] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/26/2022] [Revised: 04/05/2023] [Accepted: 04/11/2023] [Indexed: 04/23/2023]
Abstract
OBJECTIVES To determine the 99th percentile upper reference limit (URL) of high-sensitivity cardiac troponin I (hs-cTnI) in a healthy population in Xinjiang, China, and investigate the impact of ethnicity, sex, and age on this limit. DESIGN AND METHODS From September 2018 to March 2022, 5,090 Han and Uyghur adults aged 20-79 years were recruited. After questionnaire screening, 2,970 participants with physical and/or laboratory normality were enrolled. Participants recruited between September 2018 and October 2021 (2,109/2,970) were evaluated by ARCHITECTi2000 to determine the 99th percentile URL of hs-cTnI. The results were then validated in 861/2,970 participants recruited from November 2021 to March 2022. A criterion of ≤10% of test results falling outside the original determined value was used to determine whether the newly established reference intervals were valid. RESULTS The hs-cTnI concentration was higher among Uyghurs than among Han participants (p<0.001). The 99th percentile URLs were 17.52 ng/L for all participants, 18.96 ng/L for Uyghur, and 16.93 ng/L for Han. Hs-cTnI concentration was also correlated with sex and age. In the Han and Uyghur groups, male participants had a higher hs-cTnI concentration than female participants (p<0.001); the 99th percentile URLs of hs-cTnI among male and female participants were 17.80 vs. 13.67 ng/L and 19.47 vs. 16.52 ng/L, respectively. Stratified by age, hs-cTnI concentrations were higher in participants aged >60 years than in those of other age categories (p<0.001), in both the Han and Uyghur groups. Finally, <2% of these test results exceeded the newly established reference, validating the results. CONCLUSIONS This study established the 99th percentile URLs of hs-cTnI in the Xinjiang. Ethnicity and sex influence the value and should be considered.

Abstract
Background An acute coronary syndrome (ACS) event can be linked to several risk factors, including kidney disease. Currently, it is unknown if kidney disease is associated with the in-hospital mortality of patients admitted with ACS, regardless of the main confounders. In this study, we aimed to determine if kidney disease predicts in-hospital mortality among ACS patients. Methodology This is a retrospective cohort study that included patients who were admitted to the cardiology center with ACS. The patients were analyzed for their clinical characteristics, previous diseases, risk factors, and blood samples for laboratory analysis. Continuous variables were analyzed using Student’s t-test, and categorical variables using the chi-square test. A p-value of <0.05 was considered statistically significant. Results Of the 340 patients who were included in the study, 59 had ST-elevation myocardial infarction. The mean age of the patients was 62.17 years, 59.41% were male, 67.9% were Caucasian, 26% had diabetes, and 20% had a history of coronary artery disease. Age, systolic blood pressure, and a history of myocardial infarction and chronic kidney disease were linked with a higher mortality rate. In the multivariate analysis, only kidney disease was shown to be an independent marker of mortality. Conclusions Among individuals admitted with ACS, kidney disease at hospital admission is associated with increased chances of in-hospital mortality, regardless of other major and minor cardiovascular comorbidities and inflammation at baseline.

Abstract
Purpose Chronic kidney disease (CKD) is common in patients admitted with acute coronary syndrome (ACS), and it is associated with poor outcomes. However, data are limited. Hence, we examined the long-term prognostic significance of estimated glomerular filtration rate (eGFR) among Chinese patients hospitalized with ACS. Patients and Methods This is a multicenter, observational study that included 1860 ACS patients enrolled between March 2014 and June 2019 from 11 hospitals in Chengdu. CKD-EPI equation was used to calculate the baseline eGFR. Patients were divided into three groups: eGFR ≥ 90 mL/min (normal renal function), eGFR 60 to <90 mL/min (mild impaired renal function), and eGFR < 60 mL/min (moderate or severe renal dysfunction). The endpoint was all-cause death during follow-up. Results At baseline, 714 patients had normal renal function, while 746 patients had mild impaired renal function, and 400 patients had moderate or severe renal dysfunction. In the follow-up of 15 months (10 months, 22 months), 261 (14.0%) patients died;, 139 (34.8%) in the moderate or severe renal dysfunction group, 94 (12.6%) in the mild impaired renal function group, and 28 (3.9%) in the normal renal function group (log-rank p-value from Kaplan–Meier analysis <0.001). In multivariable Cox Proportional hazard analysis, age, systolic blood pressure (SBP), heart rate, eGFR, ST-elevation myocardial infarction (STEMI), and percutaneous coronary intervention (PCI) were independent predictors of all-cause death. Conclusion In this study, among Chinese patients with ACS, renal insufficiency was associated with unfavorable long-term prognosis. Age, SBP, heart rate, eGFR, STEMI, and PCI could identify those at risk.

Abstract
BACKGROUND Information is lacking on long-term management of patients with acute coronary syndrome (ACS) and chronic kidney disease (CKD) (estimated glomerular filtration rate [eGFR] < 60 mL/min/1.73 m2). OBJECTIVES Our objectives were to describe antithrombotic management patterns and outcomes in patients with ACS with varying renal function from the EPICOR (long-tErm follow-uP of antithrombotic management patterns In acute CORonary syndrome patients; NCT01171404) and EPICOR Asia (NCT01361386) studies. METHODS EPICOR and EPICOR Asia were prospective observational studies of patients who survived hospitalization for ACS and were enrolled at discharge in 28 countries across Europe, Latin America, and Asia. The studies were conducted from 2010 to 2013 and from 2011 to 2014, respectively. This analysis evaluated patient characteristics and oral antithrombotic management patterns and outcomes up to 2 years post-discharge according to admission eGFR: ≥ 90, 60-89, 30-59, or < 30 mL/min/1.73 m2. RESULTS Among 22,380 patients with available data, eGFR < 60 mL/min/1.73 m2 was observed in 16.7%. Patients with poorer renal function were older, were at greater cardiovascular risk, and had more prior cardiovascular disease and bleeding. Patients with CKD underwent fewer cardiovascular interventions and had more in-hospital cardiovascular and bleeding events. Dual antiplatelet therapy was less likely at discharge in patients with eGFR < 30 (82.3%) than in those with ≥ 90 (91.3%) mL/min/1.73 m2 and declined more sharply during follow-up in patients with low eGFR (p < 0.0001). An adjusted proportional hazards model showed that patients with lower eGFR levels had a higher risk of cardiovascular events and bleeding. CONCLUSIONS The presence of CKD in patients with ACS was associated with less aggressive cardiovascular management and an increased risk of cardiovascular events.

Abstract
Free vitamin D is the biologically active form of vitamin D. Vitamin D deficiency is associated with cardiovascular disease, the most common cause of mortality in hemodialysis patients. The goal of our current study was to investigate the relation between blood concentrations of free 25-hydroxyvitamin D with cardiovascular events in end-stage chronic kidney disease patients on hemodialysis, because this is unknown so far. We measured free vitamin D levels in 117 stable consecutive prevalent patients in September as a surrogate of vitamin D exposure during the past 6 months, and recorded the number of cardiovascular events during the previous 6 months defined as hospitalization due to heart failure, episodes of acute coronary syndrome, and stroke. Fourteen events occurred during the observation period. In patients without any cardiovascular events the free vitamin D levels were significantly higher as compared to those with cardiovascular events (patients without events: 5.68 [4.37–9.27] pg/mL; patients with events: 4.74 [3.46–5.37] pg/mL, p = 0.015). This finding remained stable after multiple regression analysis considering confounding factors such as age, time on dialysis, preexisting diabetes, hypertension, and coronary heart disease. In conclusion, our study shows that free vitamin D serum concentrations are independently associated with major cardiovascular events in chronic kidney disease patients on dialysis.

Frequency of Renal Dysfunction and Frailty in Patients ≥80 Years of Age With Acute Coronary Syndromes. Am J Cardiol 2019; 123:729-735. [PMID: 30593340 DOI: 10.1016/j.amjcard.2018.11.048] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/16/2018] [Revised: 11/14/2018] [Accepted: 11/20/2018] [Indexed: 11/22/2022]
Abstract
Although a significant association between renal function and outcomes in patients with acute coronary syndromes (ACS) has been consistently described, little information exists about the magnitude of this association in patients at older ages. No study assessed the prognostic role of renal function according to frailty in patients with ACS. The LONGEVO-SCA registry included unselected ACS patients aged ≥80 years. Frailty was asessesed by the FRAIL scale, and baseline creatinine clearance was calculated by the Cockroff-Gault formula. We evaluated the impact of renal function on mortality or readmission at 6-months according to frailty status by the Cox regression method. A total of 473 patients were assessed, with a mean age of 84.2 years. The distribution of patients across estimated glomerular filtration rate (eGFR) subgroups was as follows: (1) <30 ml/min: n = 76 (16.1%); (2) 30 to 44 ml/min: n = 147 (31.1%); (3) 45 to 60 ml/min: n = 136 (28.8%); and (4) >60 ml/min: n = 114 (24.1%). Patients with lower eGFR values were older, had a higher proportion of comorbidities and other geriatric syndromes (p = 0.001) and underwent less often an invasive management during admission (p < 0.001). The incidence of mortality or readmission at 6 months progressively increased across renal function subgroups (p = 0.001). After adjusting for potential confounders, this association became nonsignificant (p = 0.802). The association between eGFR and outcomes was only significant in patients without frailty (p = 0.001). In conclusion, most patients aged ≥80 years with NSTEACS had renal function impairment at admission. The association between renal function and outcomes was different according to frailty status.

Abstract
BACKGROUND Pivotal clinical trials found that ticagrelor reduced ischaemic complications to a greater extent than clopidogrel, and also that the benefit gradually increased with the reduction in creatinine clearance. However, the underlying mechanisms remains poorly explored. METHODS This was a single-centre, prospective, randomized clinical trial involving 60 hospitalized Adenosine Diphosphate (ADP) P2Y12 receptor inhibitor-naïve patients with chronic kidney disease (CKD) (estimated glomerular filtration rate <60 ml min-1 1.73 m-2 ) and non-ST-elevation acute coronary syndromes (NSTE-ACS). Eligible patients were randomly assigned in a 1:1 ratio to receive ticagrelor (180 mg loading dose, then followed by 90 mg twice daily) or clopidogrel (600 mg loading dose, then followed by 75 mg once daily). The primary endpoint was the P2Y12 reactive unit (PRU) value assessed by VerifyNow at 30 days. The plasma concentrations of ticagrelor and clopidogrel and their active metabolites were measured in the first 10 patients in each group at baseline, and at 1 h, 2 h, 4 h, 8 h, 12 h and 24 h after the loading dose. RESULTS Baseline characteristics were well matched between the two groups. Our results indicated a markedly lower PRU in patients treated with ticagrelor vs. clopidogrel at 30 days (32.6 ± 11.29 vs. 203.7 ± 17.92; P < 0.001) as well as at 2 h, 8 h and 24 h after the loading dose (P < 0.001). Ticagrelor and its active metabolite AR-C124910XX showed a similar time to reach maximum concentration (Cmax ) of 8 h, with the maximum concentration (Cmax ) of 355 (242.50-522.00) ng ml-1 and 63.20 (50.80-85.15) ng ml-1 , respectively. Both clopidogrel and its active metabolite approached the Cmax at 2 h, with a similar Cmax of 8.67 (6.64-27.75) ng ml-1 vs. 8.53 (6.94-15.93) ng ml-1 . CONCLUSION Ticagrelor showed much more potent platelet inhibition in comparison with clopidogrel in patients with CKD and NSTE-ACS.

Abstract
Background Acute coronary syndrome (ACS) remains a leading cause of death in the United States. Numerous studies have shown that the degree of LV systolic dysfunction is a major if not the most important determinant of long-term outcome in ACS. Objectives To identify the most important risk factors and other clinical predictors which might have impact on left ventricular ejection fraction in patients with ACS. Results The total patients (299) admitted to our center from July, 2015 till December, 2015; with established diagnosis of ACS were classified in to two groups: Group I: 193 patients with impaired LVEF < 40% (64.5%), Group II: 106 patients with LVEF equal or > 40% (35.5%). The patients of group I were significant elderly compared to those of group II (60.9 ± 11.2 vs 56.9 ± 10.6; p = 0.002), had significant history of DM and CKD (66.3% and 31.1% VS 49.1% and 19.8%; p = 0.004 and 0.036 respectively), presented mainly with STEMI- ACS (51.3% VS 28.3% respectively; p < 0.001) with +v cardiac biomarker (troponin) (90.2% VS 66.0%; p < 0.001). Moreover, patients of group I had more significant ischemic MR compared to the patients of group II (24.9% VS 3.8% respectively; p < 0.001) with higher rate of LV thrombus discovered by echocardiography (25.4% VS 1.9%; p < 0.001). Extensive significant CAD disease was observed to be higher among patients of group I (69.4% VS 57.5%; p = 0.039) and those patients treated mainly with PCI revascularization therapy (68.9% VS 52.8%; p = 0.002) compared to patients of group II who mainly treated medically (34.9% VS 17.6 %; p < 0.001). Multiple logistic regression analysis demonstrated that DM (odd ratio (OR): 2.64, 95% confidence interval (CI): 1.45-4.79, P = 0.01), presence of significant ischemic MR (OR: 13.7, 95% CI:2.84-66.1, p = 0.001)and presence of significantly diseased coronary vessels (odd ratio (OR): 5.06, 95% confidence interval (CI): 1.14-22.6, P = 0.033,) all were independent predictors for significant LV dysfunction (LVEF < 40%) which predict poor outcome in ACS patients. Conclusion We concluded that DM, presence of significant ischemic MR, and increased number, severity of diseased coronaries all were independent predictors of LV dysfunction (LVEF < 40%) which is known to predict poor outcome. Identification of those risk predictors upon patient evaluation could be helpful to identify high risk-patients, in need of particular care, aggressive therapy and close follow-up to improve their poor outcome.

ST-segment category at acute presentation is associated with the time course of coronary artery disease progression in patients with acute coronary syndromes. Heart Vessels 2016; 32:644-652. [PMID: 27826657 DOI: 10.1007/s00380-016-0917-8] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/19/2016] [Accepted: 11/04/2016] [Indexed: 11/26/2022]
Abstract
BACKGROUND Several studies have shown higher early mortality for ST-segment elevation acute coronary syndrome (STEACS), but late mortality remains consistently higher for non-ST-segment elevation acute coronary syndrome (NSTEACS). We hypothesized that ST-segment category at acute presentation is associated with the time course of coronary artery disease progression (CP) of nonculprit lesions in patients with acute coronary syndrome (ACS). METHODS A total of 226 patients (182 men, age 65 ± 10 years) with STEACS (n = 95) or NSTEACS (n = 131) who underwent percutaneous coronary intervention (PCI) during initial hospitalization were studied. All patients underwent serial coronary angiograms (CAGs) performed immediately before PCI and at 7 ± 3 months and 60 ± 10 months after presentation. CP was defined as an increase in stenosis severity >15% of a nonculprit lesion between 2 serial CAGs. RESULTS The rate of CP between the first and second CAGs did not differ by ST-segment category at acute presentation. Compared to STEACS, NSTEACS had a higher rate of CP between the second and final CAGs (27.4 vs. 42.7%, P = 0.018). Multivariate analysis showed that the independent predictors of CP between the second and final CAGs were NSTEACS (odds ratio 2.709, P = 0.003), estimated glomerular filtration rate <60 ml/min/1.73 m2 (odds ratio 2.447, P = 0.015), and diabetes mellitus (odds ratio 2.135, P = 0.021). CONCLUSIONS Irrespective of conventional risk factors and angiographic findings, ST-segment category at initial presentation is associated with the persistency of widespread coronary disease activity following presentation in ACS patients undergoing PCI. This may partly explain the time-dependent differences in outcomes of patients with STEACS and NSTEACS.

Abstract
BACKGROUND Patients with non-ST-elevation acute coronary syndrome are heterogeneous in terms of clinical presentation and immediate- and long-term risk of death or non-fatal ischemic events. The aim of the present study was to evaluate the relationship between the Global Registry of Acute Coronary Events (GRACE) score and severity of coronary artery disease angiographically evaluated by Gensini score in patients with non-ST-elevation acute coronary syndrome. METHODS A total of 245 patients with non-ST-elevation acute coronary syndrome were enrolled to the study. Based on the GRACE risk score classification system, the patients were divided into low- (n=97, 39.6%), intermediate- (n=84, 34.3%), and high- (n=64, 26.1%) risk groups. All patients underwent coronary angiography within five days after admission. RESULTS The Gensini scores were 26±29 in the low-risk group, 29±19 in the intermediate-risk group, and 38±23 in the high-risk group (p=0.016). The low-risk group was significantly different from the high-risk group (p=0.013), and the difference from the intermediate-risk group almost reached significance. Normal, noncritical, one and two, or multivessel disease were identified in 15 (6.1%), 31 (12.7%), 75 (30.6%), and 124 (50.6%) patients, respectively. The prevalence of multivessel disease was 28% in the low-risk group, 30% in the intermediate-risk group, and 42% in the high-risk group. The high-risk group was significantly different from the low-risk group (p<0.01). CONCLUSION Our study demonstrates that the GRACE score has significant value for assessing the severity and extent of coronary artery stenosis in patients with non-ST-elevation acute coronary syndrome.

Prediction of cardiovascular events in pre-dialysis chronic kidney disease patients with normal SPECT myocardial perfusion imaging. J Cardiol 2013; 63:154-8. [PMID: 24001741 DOI: 10.1016/j.jjcc.2013.07.011] [Citation(s) in RCA: 9] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/23/2013] [Revised: 07/06/2013] [Accepted: 07/22/2013] [Indexed: 11/20/2022]
Abstract
PURPOSE Patients with normal stress myocardial perfusion imaging (MPI) results generally have an excellent prognosis with <1% cardiovascular events/year. Chronic kidney disease (CKD) is an established risk factor for cardiovascular events. However, the estimated glomerular filtration rate (eGFR) varies considerably among patients with CKD. We evaluated the prognostic value of eGFR for patients with CKD who did not undergo hemodialysis and had no evidence of coronary artery disease (CAD). METHODS AND SUBJECTS Patients with CKD (n=108; 58 males; mean age: 74 years) with no CAD [no previous CAD and normal stress MPI results; summed stress score (SSS) <4] and with no history of hemodialysis were followed-up (mean duration: 24 months). CKD was defined by eGFR of <60 ml/min/1.73 m(2) and/or persistent proteinuria. Cardiovascular events included cardiac death, non-fatal myocardial infarction, and unstable angina. RESULTS Cardiovascular events were observed in 8 patients with CKD (7%). The following were determined as significant predictors of these events: age (hazard ratio=1.14; p=0.019), hemoglobin levels (hazard ratio=0.69; p=0.021), eGFR (hazard ratio=0.94; p=0.008), SSS (hazard ratio=2.31; p=0.012), and summed difference score (hazard ratio=2.33; p=0.014). CONCLUSIONS Patients with CKD and with no previous CAD and normal stress MPI results (SSS<4) may not exhibit an excellent cardiovascular prognosis. Further, a lower eGFR and stress MPI results may be the predictors of cardiovascular events. Thus, patients with a lower eGFR and/or normal stress MPI results (SSS<4) may require continuous follow-up.

Abstract
Stanford type A and open false lumen are accepted predictors for in-hospital mortality in patients with acute aortic dissection (AAD). However, the association of renal dysfunction on admission with in-hospital mortality is not well known. The aim of this study was to investigate the prognostic value of renal dysfunction in patients with AAD. A total of 250 patients with type B AAD admitted to our institution between January 2003 and August 2011 were enrolled in this study. In multivariate logistic regression analysis, the significant predictors of in-hospital mortality were age (odds ratio [OR] 1.575, 95% confidence interval [CI] 1.078-2.864, p = 0.024), maximum aortic diameter measured by an initial computed tomography (CT) (OR 1.740, 95% CI 1.029-2.940, p = 0.039), decreased enhancement of kidney (OR 7.716, 95% CI 2.335-25.501, p = 0.001) and estimated glomerular filtration rate (eGFR) <60 ml/min/1.73m(2) on admission (OR 2.782, 95% CI 1.062-7.283, p = 0.037). In conclusions the results identified a renal dysfunction on admission as the independent predictor of in-hospital mortality in type B AAD. Further investigations are needed to evaluate therapies and strategies for decreasing the deterioration of renal function to improve in-hospital mortality in patients with AAD.

Relation of estimated glomerular filtration rate and body mass index to mortality in non-dialysis patients with coronary artery disease: a report from the ET-CHD registry, 1997-2003. J Cardiol 2013; 62:144-50. [PMID: 23731921 DOI: 10.1016/j.jjcc.2013.03.016] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/24/2012] [Revised: 02/16/2013] [Accepted: 03/27/2013] [Indexed: 01/23/2023]
Abstract
BACKGROUND Low estimated glomerular filtration rate (eGFR) and body mass index (BMI) have been known as poor prognostic factors in patients with coronary artery disease (CAD). Besides, high BMI was associated with higher survival rate in patients on dialysis as well. However, the relation of eGFR and BMI to mortality has not been clarified in non-dialysis CAD patients. METHODS We studied a cohort of 1243 non-dialysis patients with angiographic CAD from the ET-CHD registry during 1997-2003 in Taiwan. To evaluate the relation of eGFR and BMI to mortality, the subjects were categorized into 4 groups by BMI higher or lower than 25 kg/m2 and eGFR higher or lower than 60 mL/min/1.73 m2, a cut-off value for chronic kidney disease (CKD). At a mean follow-up of 5.4 years, cardiac and all-cause deaths were the primary end points. RESULTS In the high BMI group, CKD was a strong predictor of cardiac and overall mortality [hazard ratio (HR): 1.63 (95% CI: 1.05-2.53) and 2.17 (95% CI: 1.54-3.07), respectively]. Besides, CKD marginally elevated the mortality risk in the low BMI group. Among CKD patients, BMI was not associated with mortality except for a high death rate in patients with BMI lower than 21 kg/m2. In contrast, in non-CKD patients, high BMI group had a lower cardiac and overall mortality than the low BMI group [HR: 0.75 (95% CI: 0.48-1.16) and 0.55 (95% CI: 0.39-0.77), respectively]. CONCLUSIONS Among non-dialysis CAD patients in eastern Taiwan, lower eGFR was associated with worse prognosis regardless of BMI levels. Notably, in patients with high BMI, the relationship between CKD and mortality was extremely remarkable. Moreover, the obesity-mortality paradox phenomenon was not present in non-dialysis CKD patients.
