An elevated triglyceride-glucose index predicts adverse outcomes and interacts with the treatment strategy in patients with three-vessel disease. Cardiovasc Diabetol 2023; 22:333. [PMID: 38057801 DOI: 10.1186/s12933-023-02063-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/02/2023] [Accepted: 11/13/2023] [Indexed: 12/08/2023] Open
Abstract
BACKGROUND Insulin resistance is a pivotal risk factor for cardiovascular diseases, and the triglyceride-glucose (TyG) index is a well-established surrogate of insulin resistance. This study aimed to investigate the prognostic value of the TyG index and its ability in therapy guidance in patients with three-vessel disease (TVD). METHODS A total of 8862 patients with TVD with available baseline TyG index data were included in the study. The endpoint was major adverse cardiac events (MACE). All patients received coronary artery bypass grafting (CABG), percutaneous coronary intervention (PCI), or medical therapy (MT) alone reasonably. RESULTS An elevated TyG index was defined as the TyG index greater than 9.51. During a median follow-up of 7.5 years, an elevated TyG index was significantly associated with an increased risk of MACE (adjusted hazard ratio 1.161, 95% confidence interval 1.026-1.314, p = 0.018). The elevated TyG index was shown to have a more pronounced predictive value for MACE in patients with diabetes, but failed to predict MACE among those without diabetes, whether they presented with stable angina pectoris (SAP) or acute coronary syndrome (ACS). Meanwhile, the association between an elevated TyG index and MACE was also found in patients with left main involvement. Notably, CABG conferred a significant survival advantage over PCI in patients with a normal TyG index, but was not observed to be superior to PCI in patients with an elevated TyG index unless the patients had both ACS and diabetes. In addition, the benefit was shown to be similar between MT and revascularisation among patients with SAP and an elevated TyG index. CONCLUSIONS The TyG index is a potential indicator for risk stratification and therapeutic decision-making in patients with TVD.

Abstract
INTRODUCTION Limited data are available on the long-term impact of mild renal dysfunction (estimated glomerular filtration rate [eGFR] 60-89 mL/min/1.73 m2) in patients with three-vessel coronary disease (3VD). METHODS A total of 5,272 patients with 3VD undergoing revascularization were included and were categorized into 3 groups: normal renal function (eGFR ≥90 mL/min/1.73 m2, n = 2,352), mild renal dysfunction (eGFR 60-89, n = 2,501), and moderate renal dysfunction (eGFR 30-59, n = 419). Primary endpoint was all-cause death. Secondary endpoints included cardiac death and major adverse cardiac and cerebrovascular events (MACCE), a composite of death, myocardial infarction, and stroke. RESULTS During the median 7.6-year follow-up period, 555 (10.5%) deaths occurred. After multivariable adjustment, patients with mild and moderate renal dysfunction had significantly higher risks of all-cause death (adjusted hazard ratio [HR]: 1.36, 95% confidence interval [CI]: 1.07-1.70; adjusted HR: 2.06, 95% CI: 1.53-2.78, respectively) compared with patients with normal renal function. Patients after coronary artery bypass grafting (CABG) had a lower rate of all-cause death and MACCE than those undergoing percutaneous coronary intervention (PCI) in the normal and mild renal dysfunction group but not in the moderate renal dysfunction group. Results were similar after propensity score matching. CONCLUSIONS In patients with 3VD, even mild renal impairment was significantly associated with a higher risk of all-cause death. The superiority of CABG over PCI diminished in those with moderate renal dysfunction. Our study alerts clinicians to the early screening of mild renal impairment in patients with 3VD and provides real-world evidence on the optimal revascularization strategy in patients with renal impairment.

Impact of residual angina on long-term clinical outcomes after percutaneous coronary intervention or coronary artery bypass graft for complex coronary artery disease. EUROPEAN HEART JOURNAL. QUALITY OF CARE & CLINICAL OUTCOMES 2023; 9:490-501. [PMID: 36001991 PMCID: PMC10405129 DOI: 10.1093/ehjqcco/qcac052] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/25/2022] [Revised: 08/01/2022] [Accepted: 08/25/2022] [Indexed: 06/15/2023]
Abstract
AIMS The aim of this study was to investigate the impact on 10-year survival of patient-reported anginal status at 1 year following percutaneous coronary intervention (PCI) or coronary artery bypass graft (CABG) in patients with left main coronary artery disease (LMCAD) and/or three-vessel CAD (3VD). METHODS AND RESULTS In this post hoc analysis of the randomized SYNTAX Extended Survival study, patients were classified as having residual angina (RA) if their self-reported Seattle Angina Questionnaire angina frequency (SAQ-AF) scale was ≤90 at the 1-year follow-up post-revascularization with PCI or CABG. The primary endpoint of all-cause death at 10 years was compared between the RA and no-RA groups. A sensitivity analysis was performed using a 6-month SAQ-AF.At 1 year, 373 (26.1%) out of 1428 patients reported RA. Whilst RA at 1 year was an independent correlate of repeat revascularization at 5 years [18.3 vs. 11.5%; adjusted hazard ratio (HR): 1.54; 95% confidence interval (CI): 1.10-2.15], it was not associated with all-cause death at 10 years (22.1 vs. 21.6%; adjusted HR: 1.11; 95% CI: 0.83-1.47). These results were consistent when stratified by the modality of revascularization (PCI or CABG) or by anginal frequency. The sensitivity analysis replicating the analyses based on 6-month angina status resulted in similar findings. CONCLUSION Among patients with LMCAD and/or 3VD, patient-reported RA at 1 year post-revascularization was independently associated with repeat revascularization at 5 years; however, it did not significantly increase 10-year mortality, irrespective of the primary modality of revascularization or severity of RA.

Predictive value of high sensitivity C-reactive protein in three-vessel disease patients with and without type 2 diabetes. Cardiovasc Diabetol 2023; 22:91. [PMID: 37081535 PMCID: PMC10120230 DOI: 10.1186/s12933-023-01830-7] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/08/2023] [Accepted: 04/08/2023] [Indexed: 04/22/2023] Open
Abstract
BACKGROUND Diabetes mellitus (DM) and atherosclerosis are multifactorial conditions and share a common inflammatory basis. Three-vessel disease (TVD) represents a major challenge for coronary intervention. Nonetheless, the predictive value of high-sensitivity C-reactive protein (hs-CRP) for TVD patients with or without type 2 DM remains unknown. Herein, we aimed to ascertain the long-term predictive value of hs-CRP in TVD patients according to type 2 DM status from a large cohort. METHODS A total of 2734 TVD patients with (n = 1040, 38%) and without (n = 1694, 62%) type 2 diabetes were stratified based on the hs-CRP (< 2 mg/L vs. ≥ 2 mg/L). Three multivariable analysis models were performed to evaluate the effect of potential confounders on the relationship between hs-CRP level and clinical outcomes. The Concordance index, net reclassification improvement (NRI), and integrated discrimination improvement (IDI) were calculated to assess the added effect of hs-CRP and the baseline model with established risk factors on the discrimination of clinical outcomes. The primary endpoint was major adverse cardiac and cerebrovascular events (MACCE). RESULTS The median follow-up duration was 2.4 years. Multivariate Cox regression analyses showed that the incidence of MACCE (adjusted hazard ratio [HR] 1.17, 95% confidence interval [CI] 1.01-1.35, p = 0.031) and all-cause death (HR 1.82, 95% CI 1.07-3.11, p = 0.026) were significantly higher in the diabetic group compared to the non-diabetic group. In the diabetic group, the incidence of MACCE (adjusted HR 1.51, 95% CI 1.09-2.10, p = 0.013) was significantly higher in the high hs-CRP group than in the low hs-CRP group; no significant difference was found for all-cause death (HR 1.63; 95% CI 0.58-4.58, p = 0.349). In the non-diabetic group, the prevalence of MACCE (adjusted HR 0.93, 95% CI 0.71-1.22, p = 0.613) was comparable between the two groups. Finally, the NRI (0.2074, p = 0.001) and IDI (0.0086, p = 0.003) for MACCE were also significantly increased after hs-CRP was added to the baseline model in the diabetic group. CONCLUSIONS Elevated hs-CRP is an independent prognostic factor for long-term outcomes of MACCE in TVD patients with type 2 diabetes but not in those without type 2 diabetes. Compared to traditional risk factors, hs-CRP improved the risk prediction of adverse cardiovascular events in TVD patients with type 2 diabetes.

Association of lipoprotein(a) with coronary severity in patients with new-onset acute myocardial infarction: A large cross-sectional study. Clin Chim Acta 2023; 540:117220. [PMID: 36621598 DOI: 10.1016/j.cca.2023.117220] [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: 11/14/2022] [Revised: 01/03/2023] [Accepted: 01/03/2023] [Indexed: 01/07/2023]
Abstract
BACKGROUND Although current evidence suggests a causal association between lipoprotein(a) [Lp(a)] and cardiovascular disease, there is still no consensus on its association with coronary severity in new-onset acute myocardial infarction (AMI). We explored the association of Lp(a) with coronary severity. METHODS In this large cross-sectional study, we enrolled 2,740 patients with new-onset AMI from the Zhongda Hospital affiliated to Southeast University. Lp(a) was considered as an exposure variable. Gensini score, left main disease and three-vessel disease were used to assess coronary severity. Multivariate logistic regression, restricted cubic spline (RCS) models and threshold effects were used to analyze the association of Lp(a) with coronary severity. RESULTS Multivariate adjusted models showed that Lp(a) was independently associated with Gensini score (≥100), left main disease and three-vessel disease [Q4 vs Q1, OR (95 % CI), P value: 2.301 (1.770, 2.992), P < 0.001; 1.743 (1.174, 2.587), P = 0.006; 1.431 (1.128, 1.816), P = 0.003; respectively], and the associations persisted in sensitivity analyses and most subgroups (P < 0.05). Additionally, the RCS showed that Lp(a) was nonlinearly associated with Gensini score (continuous variable), Gensini score (≥100) and three-vessel disease (P for nonlinearity < 0.05). Threshold effects analysis showed that Lp(a) above the inflection point was positively associated with Gensini score (continuous variable) as well as the risk of Gensini score (≥100) and three-vessel disease. CONCLUSION Lp(a) was closely associated with coronary severity represented by Gensini score, left main disease and three-vessel disease in patients with new-onset AMI.

Sex differences in coronary angiographic findings in patients with stable chest pain: analysis of data from the KoRean wOmen'S chest pain rEgistry (KoROSE). Biol Sex Differ 2022; 13:2. [PMID: 34980251 PMCID: PMC8722299 DOI: 10.1186/s13293-021-00411-1] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/30/2021] [Accepted: 12/22/2021] [Indexed: 12/15/2022] Open
Abstract
Background Focused evaluations on potential sex differences in the angiographic findings of the coronary arteries are scarce. This study was performed to compare the angiographic extent and localization of coronary stenosis between men and women. Methods A total of 2348 patients (mean age 62.5 years and 60% women) with stable chest pain undergoing invasive coronary angiography (CAG) were recruited from the database of the nation-wide chest pain registry. Obstructive coronary artery disease (CAD) was defined as ≥ 50% stenosis of the left main coronary artery and/or ≥ 70% stenosis of any other epicardial coronary arteries. Results Although women were older than men (64.4 ± 10.3 vs. 59.5 ± 11.4 years, P < 0.001), men had worse risk profiles including high blood pressure, more frequent smoking and elevated triglyceride and C-reactive protein. The prevalence of obstructive CAD was significantly higher in men than in women (37.0% vs. 28.4%, P < 0.001). Men had a higher prevalence of LM disease (10.3% vs. 3.5%, P < 0.001) and three-vessel disease (16.1% vs. 9.5%, P = 0.007) compared to women. In multiple binary logistic regression analysis, the risk of men having LM disease or three-vessel disease was 7.4 (95% confidence interval 3.48–15.97; P < 0.001) and 2.7 (95% confidence interval 1.57–4.64; P < 0.001) times that of women, respectively, even after controlling for potential confounders. Conclusions In patients with chest pain undergoing invasive CAG, men had higher obstructive CAD prevalence and more high-risk angiographic findings such as LM disease or three-vessel disease. Supplementary Information The online version contains supplementary material available at 10.1186/s13293-021-00411-1. Focused evaluation on sex differences in the angiographic findings of the coronary arteries is limited. We evaluated sex differences in the angiographic extent and localization of coronary stenosis in 2348 patients. Men had higher prevalence of obstructive coronary artery disease and more high-risk angiographic findings such as left main disease or three-vessel disease. This sex difference could be applied in the clinical evaluation and management of patients with suspected coronary artery disease.

Ten-year all-cause death following percutaneous or surgical revascularization in patients with prior cerebrovascular disease: insights from the SYNTAX Extended Survival study. Clin Res Cardiol 2021; 110:1543-1553. [PMID: 33517534 PMCID: PMC8484131 DOI: 10.1007/s00392-020-01802-x] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/23/2020] [Accepted: 12/29/2020] [Indexed: 11/09/2022]
Abstract
BACKGROUND Coronary bypass artery grafting (CABG) has a higher procedural risk of stroke than percutaneous coronary intervention (PCI), but may offer better long-term survival. The optimal revascularization strategy for patients with prior cerebrovascular disease (CEVD) remains unclear. METHODS AND RESULTS The SYNTAXES study assessed the vital status out to 10 year of patients with three-vessel disease and/or left main coronary artery disease enrolled in the SYNTAX trial. The relative efficacy of PCI vs. CABG in terms of 10 year all-cause death was assessed according to prior CEVD. The primary endpoint was 10 year all-cause death. The status of prior CEVD was available in 1791 (99.5%) patients, of whom 253 patients had prior CEVD. Patients with prior CEVD were older and had more comorbidities (medically treated diabetes, insulin-dependent diabetes, metabolic syndrome, peripheral vascular disease, chronic obstructive pulmonary disease, impaired renal function, and congestive heart failure), compared with those without prior CEVD. Prior CEVD was an independent predictor of 10 year all-cause death (adjusted HR: 1.35; 95% CI: 1.04-1.73; p = 0.021). Patients with prior CEVD had a significantly higher risk of 10 year all-cause death (41.1 vs. 24.1%; HR: 1.92; 95% CI: 1.54-2.40; p < 0.001). The risk of 10 year all-cause death was similar between patients receiving PCI or CABG irrespective of the presence of prior CEVD (p-interaction = 0.624). CONCLUSION Prior CEVD was associated with a significantly increased risk of 10 year all-cause death which was similar in patients treated with PCI or CABG. These results do not support preferential referral for PCI rather than CABG in patients with prior CEVD. TRIAL REGISTRATION SYNTAX: ClinicalTrials.gov reference: NCT00114972.

Abstract
AIMS To investigate the impact of established cardiovascular disease (CVD) on 10-year all-cause death following coronary revascularization in patients with complex coronary artery disease (CAD). METHODS The SYNTAXES study assessed vital status out to 10 years of patients with complex CAD enrolled in the SYNTAX trial. The relative efficacy of PCI versus CABG in terms of 10-year all-cause death was assessed according to co-existing CVD. RESULTS Established CVD status was recorded in 1771 (98.3%) patients, of whom 827 (46.7%) had established CVD. Compared to those without CVD, patients with CVD had a significantly higher risk of 10-year all-cause death (31.4% vs. 21.7%; adjusted HR: 1.40; 95% CI 1.08-1.80, p = 0.010). In patients with CVD, PCI had a non-significant numerically higher risk of 10-year all-cause death compared with CABG (35.9% vs. 27.2%; adjusted HR: 1.14; 95% CI 0.83-1.58, p = 0.412). The relative treatment effects of PCI versus CABG on 10-year all-cause death in patients with complex CAD were similar irrespective of the presence of CVD (p-interaction = 0.986). Only those patients with CVD in ≥ 2 territories had a higher risk of 10-year all-cause death (adjusted HR: 2.99, 95% CI 2.11-4.23, p < 0.001) compared to those without CVD. CONCLUSIONS The presence of CVD involving more than one territory was associated with a significantly increased risk of 10-year all-cause death, which was non-significantly higher in complex CAD patients treated with PCI compared with CABG. Acceptable long-term outcomes were observed, suggesting that patients with established CVD should not be precluded from undergoing invasive angiography or revascularization.

Abstract
Background There are relatively limited data regarding real-world outcomes in very old patients with three-vessel disease (3VD) receiving different therapeutic strategies. This study aimed to perform analysis of long-term clinical outcomes of medical therapy (MT), coronary artery bypass grafting (CABG), and percutaneous coronary intervention (PCI) in this population. Methods We included 711 patients aged ≥ 75 years from a prospective cohort of patients with 3VD. Consecutive enrollment of these patients began from April 2004 to February 2011 at Fu Wai Hospital. Patients were categorized into three groups (MT, n = 296; CABG, n = 129; PCI, n = 286) on the basis of different treatment strategies. Results During a median follow-up of 7.25 years, 262 deaths and 354 major adverse cardiac and cerebrovascular events (MACCE) occurred. Multivariate Cox analysis showed that the risk of cardiac death was significantly lower for CABG compared with PCI (adjusted hazard ratio [HR] = 0.475, 95% confidence interval [CI] 0.232–0.974, P = 0.042). Additionally, MACCE appeared to show a trend towards a better outcome for CABG (adjusted HR = 0.759, 95% CI 0.536–1.074, P = 0.119). Furthermore, CABG was significantly superior in terms of unplanned revascularization (adjusted HR = 0.279, 95% CI 0.079–0.982, P = 0.047) and myocardial infarction (adjusted HR = 0.196, 95% CI 0.043–0.892, P = 0.035). No significant difference in all-cause death between CABG and PCI was observed. MT had a higher risk of cardiac death than PCI (adjusted HR = 1.636, 95% CI 1.092–2.449, P = 0.017). Subgroup analysis showed that there was a significant interaction between treatment strategy (PCI vs. CABG) and sex for MACCE (P = 0.026), with a lower risk in men for CABG compared with that of PCI, but not in women. Conclusions CABG can be performed with reasonable results in very old patients with 3VD. Sex should be taken into consideration in therapeutic decision-making in this population.

Predictive value of free triiodothyronine (FT3) to free thyroxine (FT4) ratio in long-term outcomes of euthyroid patients with three-vessel coronary artery disease. Nutr Metab Cardiovasc Dis 2021; 31:579-586. [PMID: 33250369 DOI: 10.1016/j.numecd.2020.10.011] [Citation(s) in RCA: 18] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/11/2020] [Revised: 10/04/2020] [Accepted: 10/13/2020] [Indexed: 12/29/2022]
Abstract
BACKGROUND AND AIMS Whether routine assessment of FT3/FT4 ratio in euthyroid patients with three-vessel disease (3VD) could help identify high-risk individuals remains unclear. This study evaluated the relationship between FT3/FT4 ratio and long-term clinical outcomes in this specific population. METHODS AND RESULTS This study included 2106 euthyroid patients with 3VD (stenoses of ≥50% in right coronary artery, left circumflex and left anterior descending). Patients were categorized into three groups according to tertiles of FT3/FT4 ratio (Q1>2.58,n = 704; 2.2 ≤ Q2<2.58, n = 706; Q3<2.22, n = 696). The median follow-up time was 5.3 years, during which 206 deaths and 332 MACCEs (consisting of all-cause death, myocardial infarction, and stroke) occurred. Compared with the other two groups, patients with low level of FT3/FT4 ratio tended to be female, older, diabetic, and had significantly higher incidences of all-cause death, cardiac death and MACCE (all P < 0.05). Cox regression analysis showed that patients with low level of FT3/FT4 ratio had higher risks of long-term cardiac death (adjusted HR = 1.87, 95% CI 1.06-3.28, P = 0.030) and MACCE (adjusted HR = 1.43, 95% CI 1.07-1.93, P = 0.017) than those with high level of FT3/FT4 ratio. Subgroup analysis showed there was a significant interaction between FT3/FT4 ratio and age (≥65 years vs.<65 years) for MACCE (P = 0.029). CONCLUSION Low level of FT3/FT4 ratio is independently associated with an increased risk of long-term cardiac death and MACCE in euthyroid patients with 3VD. Routine assessment of FT3/FT4 ratio might be helpful to identify high-risk individuals in this specific population.

Abstract
AIMS To evaluate the impact of various smoking status on 10-year all-cause mortality and to examine a relative treatment benefit of coronary artery bypass grafting (CABG) vs. percutaneous coronary intervention (PCI) according to smoking habits. METHODS AND RESULTS The SYNTAX Extended Survival study evaluated vital status up to 10 years in 1800 patients with de novo three-vessel disease and/or left main coronary artery disease randomized to CABG or PCI in the SYNTAX trial. In the present analysis, patients were divided into three groups (current, former, or never smokers), and the primary endpoint of 10-year all-cause mortality was assessed according to smoking status. Smoking status was available in 1793 (99.6%) patients at the time of randomization, of whom 363 were current smokers, 798 were former smokers, and 632 were never smokers. The crude rates of 10-year all-cause mortality were 29.7% in current smokers, 25.3% in former smokers, and 25.9% in never smokers (Log-rank P = 0.343). After adjustment for imbalances in baseline characteristics, current smokers had a significantly higher risk of 10-year all-cause mortality than never smokers [adjusted hazard ratio (aHR): 2.29; 95% confidence interval (CI): 1.60-3.27; P < 0.001], whereas former smokers did not. PCI was associated with a higher risk of all-cause mortality than CABG among current smokers (HR: 1.60; 95% CI: 1.09-2.35; P = 0.017), but it failed to show a significant interaction between revascularization strategies and smoking status (Pinteraction = 0.910). CONCLUSION Current smokers had a higher adjusted risk of 10-year all-cause mortality, whereas former smokers did not. The treatment effect of CABG vs. PCI did not differ significantly according to smoking status. CLINICAL TRIAL REGISTRATION SYNTAX: ClinicalTrials.gov reference: NCT00114972; SYNTAX Extended Survival.

Prediabetes and long-term outcomes in patients with three-vessel coronary artery disease: A large single-center cohort study. J Diabetes Investig 2020; 12:409-416. [PMID: 32686328 PMCID: PMC7926245 DOI: 10.1111/jdi.13361] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/09/2020] [Revised: 07/09/2020] [Accepted: 07/10/2020] [Indexed: 01/01/2023] Open
Abstract
Aims/Introduction Whether detection of prediabetes by routinely testing hemoglobin A1c and fasting plasma glucose in three‐vessel disease patients could identify individuals at high risk of future cardiovascular disease events remains unclear. This study evaluated the relationship between different glycemic status and clinical outcomes in this specific population. Materials and Methods This study included 8,891 Chinese patients with three‐vessel disease. Patients were categorized according to their glycemic status (normoglycemia [NG], n = 3,195; prediabetes, n = 1,978; diabetes mellitus, n = 3,718). Results The median follow‐up time was 7.5 years, during which 1,354 deaths and 2,340 major adverse cardiac and cerebrovascular events occurred. Compared with the NG group, patients in the prediabetes and diabetes mellitus groups had more comorbidities. After adjusting for confounders, the diabetes mellitus group had a higher risk of all‐cause death (hazard ratio [HR] 1.36, 95% confidence interval [CI] 1.20–1.53; P < 0.001), cardiac death (HR 1.35, 95% CI 1.14–1.61; P = 0.001) and major adverse cardiac and cerebrovascular events (HR 1.22, 95% CI 1.11–1.34; P < 0.001) compared with the NG group, whereas the prediabetes and NG groups had no significant difference. The diabetes mellitus group also had a higher risk of stroke compared with the NG group (HR 1.22, 95% CI 1.02–1.46; P = 0.031). Conclusions In the context of three‐vessel disease, prediabetes patients have comparable long‐term outcomes in terms of major adverse cardiac and cerebrovascular events, cardiac death and all‐cause death to those with NG. Routine screening of glycemic metabolism based on hemoglobin A1c and fasting plasma glucose might be valuable to identify individuals with diabetes mellitus who are at high risk of future cardiovascular disease events and individuals with prediabetes who are at high risk of progressing to diabetes mellitus.

Susceptible gene polymorphism in patients with three-vessel coronary artery disease. BMC Cardiovasc Disord 2020; 20:172. [PMID: 32293292 PMCID: PMC7161109 DOI: 10.1186/s12872-020-01449-6] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/25/2019] [Accepted: 03/26/2020] [Indexed: 01/24/2023] Open
Abstract
Background Data of susceptible gene polymorphisms related to progression of coronary atherosclerosis in patients with three-vessel disease (TVD) is limited in China. This case-control study aimed to analyze the differences of variant carrier frequencies between cases and controls, and to explain the possible genetic effects on the progression of TVD. Methods A total of 8943 TVD patients were consecutively enrolled. Major adverse cardiac and cerebrovascular events (MACCE) included all-cause death, acute myocardial infarction, repeat revascularization, readmission and stroke. Patients with 1-year MACCE in this cohort were selected as MACCE group. Blood samples from MACCE group and non-CAD control groups were collected, and a deoxyribonucleic acid library was created. A total of 34 tag or hot single nucleotide polymorphisms (SNPs) in six genes including CDKN2B-AS1, ADAMTS7, ABO, ADAMTS13, IL-18, and PECAM1 were analyzed by a SNPscan™ multi-genotyping kit. Carrier frequencies of each SNP were compared between the two groups using dominant, recessive and codominant allele model, respectively. Multivariate logistic regression model was established. Results Variant allele frequencies of rs10757274, rs1333042, rs1333049, rs4977574, rs9632884, rs1063192 and rs3217986 on CDKN2B-AS1 gene showed significant differences between the two groups in at least one allele model. Variant allele frequency of rs3217986 was not statistically significant after adjusting for the false discovery rate using Benjamini-Hochberg procedure (Q > 0.05). Variant allele frequencies of rs1333049, rs10757274, rs4977574 on CDKN2B-AS1 gene were significantly higher in MACCE group in all dominant, recessive and codominant models. Rs1055432 on ADAMTS13 and rs8176694 on ABO gene showed threshold significance between the two groups. After multivariable adjustment, G mutant homozygous rs9632884 (GG vs. GC + CC) (OR: 0.24; 95% CI: 0.09–0.65; P = 0.005) on CDKN2B-AS1 gene were independent protective factor of MACCE in recessive model. Conclusions In patients with TVD in China, variant alleles on CDKN2B-AS1 gene may form part of the genetic basis of coronary atherosclerosis progression, promoting or suppressing ischemic events.

Association Between Residual Platelet Reactivity on Clopidogrel Treatment and Severity of Coronary Atherosclerosis: Intrinsic Hypercoagulability as a Mediator. Adv Ther 2019; 36:2296-2309. [PMID: 31372962 DOI: 10.1007/s12325-019-01032-2] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/11/2019] [Indexed: 01/20/2023]
Abstract
INTRODUCTION High on-treatment residual platelet reactivity (HRPR) was associated with greater atherosclerosis burden. We examined whether intrinsic hypercoagulability (IHC) could be attributed to that association in patients treated by drug-eluting stents. METHODS This retrospective observation enrolled a total of 891 coronary artery disease (CAD) subjects. Platelet and coagulant reactivity was measured by thrombelastography. At least 24 h after a 300-mg dose of clopidogrel, adenosine diphosphate (ADP)-induced maximum amplitude of clot strength (MAadp) > 47 mm represented HRPR. Thrombin-induced platelet-fibrin clot strength (MAthrombin) and blood fibrinogen surrogated intrinsic coagulability. Using mediation analysis to evaluate the effect of IHC on the relationship between the number of narrowed coronaries and HRPR on clopidogrel. RESULTS More HRPR on clopidogrel and higher intrinsic coagulability were observed in more severe coronary atherosclerosis, especially in the three-vessel disease. After adjustment for confounding factors, the number of narrowed coronaries (ORadj = 1.343, 95% CI 1.063-1.695, p = 0.013), MAthrombin (ORadj = 1.106, 95% CI 1.058-1.157, p < 0.001), and fibrinogen (ORadj = 1.003, 95% CI 1.001-1.005, p = 0.012) were all independent positive predictors for HRPR. MAthrombin and fibrinogen were meaningful mediators for the significant positive association of the number of narrowed vessels and HRPR on clopidogrel, which were enhanced by around 30% and 43%, respectively, for this effect. CONCLUSIONS This is the first study to demonstrate that the positive correlation between the number of stenotic coronaries and HRPR on clopidogrel may be partly attributed to IHC, which may enhance the risk stratification, guide more precise coagulation in multi-vessel disease after drug-eluting stents, and therefore deserve further study.

Erectile dysfunction severity as a predictor of left main and/or three-vessel disease in acute coronary syndrome patients. Indian Heart J 2018; 70 Suppl 3:S56-S59. [PMID: 30595321 PMCID: PMC6309152 DOI: 10.1016/j.ihj.2018.05.006] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/18/2017] [Revised: 03/15/2018] [Accepted: 05/06/2018] [Indexed: 10/25/2022] Open
Abstract
BACKGROUND Coronary artery disease (CAD) is a leading cause of morbidity and death. Early diagnosis of patients with left main and/or three-vessel disease (LM/3VD) among acute coronary syndrome (ACS) patients is beneficial. The relation between erectile dysfunction (ED) and cardiovascular diseases was previously noticed. The aim of our work was to find out if the severity of ED could predict the presence of LM/3VD in ACS patients. PATIENTS AND METHODS Eighty-five male patients with ACS were included in the study. Clinical assessment, estimation of international index of erectile function (IIEF) score, and coronary angiography were performed in all patients. Gensini score was calculated to assess the severity of CAD. Based on IIEF score, the patients were divided into two groups: Group 1: patients with mild or no ED (IIEF score ≥17), Group 2: patients with moderate or severe ED (IIEF score <17). RESULTS Patients with IIEF score <17 had significantly higher prevalence of LM CAD (4.3% versus 18.4%, p=0.035), 3VD (17% versus 39.5%, p=0.021) and LM/3VD (21.3% versus 55.3%, p=0.0012), as well as higher mean Gensini score (23.5±10.8 versus 34.1±12.7, p=0.0001). The independent predictors of LM/3VD in order of significance were: age, heart rate, IIEF <17, Killip class >1, and ST-depression or ST-elevation in lead aVR ≥1mV. There was a significant negative correlation between IIEF score and Gensini score (r=-0.383, p=0.0003). CONCLUSION The presence of moderate or severe ED in men with ACS is associated with higher Gensini score and more incidence of LM/3VD. IIEF score <17 was an independent predictor of LM/3VD.

Left main and/or three-vessel disease in patients with non-ST-segment elevation myocardial infarction and low-risk GRACE score: Prevalence, clinical outcomes and predictors. Rev Port Cardiol 2018; 37:911-919. [PMID: 30449610 DOI: 10.1016/j.repc.2018.03.016] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/06/2017] [Revised: 02/19/2018] [Accepted: 03/11/2018] [Indexed: 02/07/2023] Open
Abstract
INTRODUCTION A low-risk GRACE score identifies patients with a lower incidence of major cardiac events, however it can erroneously classify patients with severe coronary artery disease as low-risk. We assessed the prevalence, clinical outcomes and predictors of left main and/or three-vessel disease (LM/3VD) in non-ST-elevation acute myocardial infarction (NSTEMI) patients with a GRACE score of ≤108 at admission. METHODS Using data from the Portuguese Registry on Acute Coronary Syndromes, 1196 patients with NSTEMI and a GRACE score of ≤108 who underwent coronary angiography were studied. Independent predictors of LM/3VD and its impact on in-hospital complications and one-year mortality were retrospectively analyzed. RESULTS LM/3VD was present in 18.2% of patients. Its prevalence was higher in males and associated with hypertension, diabetes, previous myocardial infarction, heart failure and peripheral arterial disease (PAD). Although there were no differences in in-hospital complications, these patients had higher mortality (0.9 vs. 0.0%) and more major adverse cardiac and cerebrovascular events (MACCE) (4.1 vs. 2.5%, p=0.172), and higher one-year mortality (2.4 vs. 0.5%, p=0.005). Independent predictors of LM/3VD were age (OR 1.03; 95% CI 1.01-1.0, p=0.003), male gender (OR 2.56; 95% CI 1.56-4.17, p<0.001), heart rate (1.02; 95% CI 1.01-1.03, p<0.001), PAD (OR 3.21; 95% CI 1.47-7.00, p<0.001) and heart failure (OR 3.38; 95% CI 1.02-11.15, p=0.046). CONCLUSIONS LM/3VD was found in one in five patients. These patients had a tendency for higher in-hospital mortality and more MACCE, and higher one-year mortality. Simple clinical variables could help predict this severe coronary anatomy.

Neutrophil-to-lymphocyte ratio as an independent predictor of left main and/or three-vessel disease in patients with non-ST-segment elevation myocardial infarction. CARDIOVASCULAR REVASCULARIZATION MEDICINE 2015; 16:331-5. [PMID: 26051172 DOI: 10.1016/j.carrev.2015.05.006] [Citation(s) in RCA: 8] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/19/2015] [Revised: 05/07/2015] [Accepted: 05/14/2015] [Indexed: 11/29/2022]
Abstract
BACKGROUND/PURPOSE Patients with acute coronary syndrome due to left main and/or three-vessel disease (LM/3VD) are at the highest risk of short- and long-term adverse cardiovascular events. Neutrophil-to-lymphocyte ratio (NLR) has been shown to predict the severity of coronary artery disease in various clinical settings, but its independent predictive value for LM/3VD has not been investigated in patients with non-ST-segment elevation myocardial infarction (NSTEMI). We aimed to evaluate the independent predictive value of NLR for LM/3VD in NSTEMI patients. METHODS/MATERIALS We performed a retrospective analysis of consecutive NSTEMI patients who underwent coronary angiography. NLR was calculated as the ratio of neutrophil to lymphocyte based on the laboratory data on admission. The primary outcome was the presence of LM/3VD. RESULTS In all, 396 patients were included in the final analysis. Median NLR in the entire study population was 3.43 (interquartile range, 2.12-5.51). By receiver operating characteristics curve analysis, the optimal cutoff value of NLR in predicting LM/3VD was 2.80 (area under the curve 0.60, sensitivity 73%, specificity 43%). Of the 396 patients, 244 patients (62%) had NLR ≥2.8. Patients with NLR ≥2.8 were older and had a higher prevalence of LM/3VD (30 % vs. 18%, p=0.005). According to multivariate logistic regression analysis, NLR ≥2.8 was an independent predictor of LM/3VD after adjusting for other clinical variables including ST depression and ST elevation in lead aVR (odds ratio 1.83, 95% confidence interval 1.07-3.21, p=0.03). CONCLUSION Our study demonstrates that NLR ≥2.8 is an independent predictor of LM/3VD in patients with NSTEMI.
