Correlation analysis between the expression of serum microRNA-665 and the degree of coronary artery stenosis and major adverse cardiovascular events in patients with acute myocardial infarction.

BACKGROUND: The purpose of this study was to explore the expression of miR-665 in acute myocardial infarction (AMI) and evaluate its significance in the diagnosis and prognosis of AMI. METHODS: 100 patients with AMI were selected as the study group and 80 healthy subjects were chosen as the control group. The levels of miR-665 were detected by reverse transcription quantitative polymerase chain reaction (RT-qPCR) in the two groups. The diagnostic value of miR-665 expression level in AMI was analyzed by the receiver operator characteristic (ROC) curve. Kaplan-Meier curve and Cox regression were used to evaluate the predictive value of miR-665 for major adverse cardiovascular events (MACEs) in patients with AMI within 30 days after percutaneous coronary intervention (PCI). RESULTS: The serum miR-665 level of the study group was significantly lower than that of the control group. The level of miR-665 was significantly correlated with clinical indicators of patients with AMI. ROC curve showed that miR-665 has a high diagnostic value for AMI. Survival analysis showed that Gensini score and miR-665 were independent risk factors for the occurrence of MACEs within 30 days after PCI in patients with AMI. CONCLUSIONS: Abnormal decrease of serum miR-665 expression level in patients with AMI may increase the risk of MACEs occurrence after PCI.

The evaluation value of atherogenic index of plasma and high-sensitivity C-reactive protein for the degree of coronary artery lesion in premature coronary artery disease.

BACKGROUND: Premature coronary artery disease (PCAD) is prevailing. We aimed to investigate the evaluation value of atherogenic index of plasma (AIP) and high-sensitivity C-reactive protein (hs-CRP) for the occurrence and severity of coronary artery lesion in PCAD patients. METHODS: PCAD (PACD group)/non-PCAD (control group) patients were enrolled. The coronary artery lesion degree was evaluated using Gensini score (GS). PCAD patients were allocated into the low/medium/high GS groups, with general clinical baseline data analyzed. Plasma hs-CRP/AIP levels were compared in PCAD patients with different disease degree. Correlations between plasma hs-CRP/AIP with Gensini score, independent risk factors affecting the occurrence of PCAD, and the predictive value of hs-CRP/AIP/their combination for the occurrence and degree of PCAD were evaluated by Spearman correlation analysis/Logistic multivariate regression/receiver operating characteristic (ROC) curve. The differences in the area under the curve (AUC) were compared using MedCalc-Comparison of ROC curves. RESULTS: Plasma hs-CRP/AIP levels in the PCAD group were increased. Plasma hs-CRP/AIP levels varied significantly among PCAD patients with different disease degree. Plasma hs-CRP/AIP levels were markedly positively correlated with the Gensini score. Smoking history/homocysteine/fasting blood-glucose/hs-CRP/AIP were all independent risk factors affecting PCAD occurrence. The AUC of hs-CRP and AIP combination predicting the occurrence of PCAD was 0.950 (90.80% sensitivity/93.33% specificity). hs-CRP/AIP combination assisted in predicting the disease degree in PCAD patients. CONCLUSIONS: AIP and hs-CRP are independent risk factors for the occurrence of PCAD, and their combination has high predictive value for PCAD occurrence and disease degree, which are both positively correlated with coronary artery lesion degree.

Prognostic value of serum immunoglobulin M levels in patients with acute coronary syndrome.

BACKGROUND AND AIMS: The immuno-inflammatory response is a crucial early step in the development of acute coronary syndrome (ACS). In this study, we investigated whether immunoglobulin M (IgM) in the body's initial immune response can predict the prognosis of patients with ACS. METHODS: This prospective cohort study enrolled 1556 ACS patients at Beijing Hospital between March 2017 and October 2020. All patients underwent coronary angiography (CAG). The serum IgM concentration and biochemical indicators were evaluated prior to CAG. The primary endpoint was the composite endpoint of major adverse cardiovascular and cerebrovascular events (MACCEs). Multivariate Cox proportional hazards models was used to explore the association between IgM levels and the endpoint. RESULTS: The average serum IgM levels of the population was 61.3 (42.6-88.4) mg/dL. During the median follow-up period of 55 months, 150 MACCEs occurred. Kaplan-Meier analysis showed that low serum IgM levels were associated with occurrence of MACCEs (log-rank p = 0.009). Univariate Cox proportional hazards models showed that low serum IgM (≤78.05 mg/dL) was associated with MACCEs (hazard ratio (HR) 1.648, 95 % confidence interval (CI): 1.129-2.406, p = 0.010). In patients with IgM ≤78.05 mg/dL, the HR for partially adjusted MACCEs events was 1.576 (95 % CI: 1.075-2.310) and 1.930 (95 % CI: 1.080-3.449) after adjusting for multiple covariates. The subgroup analysis showed that for patients in ≤24 BMI, never smoking and non-dyslipidemia subgroup, the lower serum IgM levels was significantly associated with the risk of MACCEs (pinteraction < 0.001, pinteraction = 0.037, pinteraction = 0.024, respectively). CONCLUSIONS: Low serum IgM levels was independently associated with MACCEs in ACS patients, especially for patients without obesity, smoking and dyslipidemia.

Serum immunoglobulin M is associated with the severity of coronary artery disease in adults.

Purpose: The purpose of this study was to investigate the relationship between serum immunoglobulin M (IgM) and the severity of coronary artery disease in Chinese patients who underwent coronary angiography. Methods: A total of 2,045 patients who underwent coronary angiography (CAG) from March 2017 to March 2020 at Beijing Hospital were included in this study. Serum IgM concentration and biochemical indicators were measured before coronary angiography (CAG). The triquartile IgM levels at baseline in the population were analysed. Spearman rank correlation was used to analyse the association between IgM and traditional risk factors for coronary artery disease (CAD). CAD patients were divided into subgroups by affected area, number of affected vessels, and Gensini score to analyse the relationship between IgM and CAD severity. Multivariable logistic regression analysis was used to evaluate the association between IgM and CAD severity. Results: Serum IgM levels were significantly lower in the CAD group (63.5 mg/dL) than in the non-coronary artery disease (NCAD) group (72.3 mg/dL) (P < 0.001). Serum IgM levels were significantly associated with sex. Serum IgM levels were positively correlated with traditional CAD risk factors such as TG, TC and LDL-C (P < 0.05), and negatively associated with the number of obstructed vessels, the number of affected areas, and Gensini scores. After adjusting for age, sex, smoking status, hypertension, dyslipidaemia, diabetes, stroke, and statin use history, a high IgM level was independently negatively associated with the severity of CAD expressed by the Gensini score. Conclusion: We determined that serum IgM was independently negatively associated with the severity of CAD diagnosed by angiography in Chinese adults.

Association between sleep apnea-specific hypoxic burden and severity of coronary artery disease.

PURPOSE: Sleep apnea-specific hypoxic burden (SASHB) is a polysomnographic metric that comprehensively measures the degree of nocturnal desaturation caused by obstructive sleep apnea. This research was conducted to elucidate the relationship between SASHB and coronary artery disease (CAD) severity. METHODS: We carried out a prospective study of hospitalized patients with CAD of unstable angina who were expected to undergo invasive coronary angiography at Beijing Anzhen Hospital from February to September 2023. SASHB values were calculated using a self-programmed C + + program. Multivariable logistic regression analysis was applied to identify the association between SASHB and the prevalence of severe CAD, documented by the Gensini Score, and the SYNTAX (Synergy between Percutaneous Coronary Intervention With Taxus and Cardiac Surgery) Score. RESULTS: This study enrolled 137 patients with a median age of 59 years, 96 (70.1%) of whom were male. A total of 125 (91.2%) patients had coronary stenosis of ≥ 50% in at least one location. Patients with a high SASHB of ≥ 18% min/h had a significantly higher Gensini Score (32.0 vs. 18.5, P = 0.002) and SYNTAX Score (14.0 vs. 7.0, P = 0.002) than those with a low SASHB. After adjusting for multiple covariates, a high SASHB was significantly associated with the prevalence of severe CAD, determined by a Gensini Score ≥ 21 (OR 2.67, P = 0.008) or a SYNTAX Score > 22 (OR 4.03, P = 0.016). CONCLUSION: Our findings revealed a robust and independent association between SASHB and CAD severity in patients with unstable angina, highlighting the potential value of SASHB as a predictor of risk and a target for interventions aimed at preventing cardiovascular diseases.

Neutrophil-to-serum iron ratio as a promising inflammatory biomarker for acute myocardial infarction and Gensini score.

Background: We aim to investigate whether the neutrophil-to-serum iron ratio (N/SI) is a promising biomarker for acute myocardial infarction group (AMI) and Gensini score. Methods: A total of 263 patients were enrolled and divided into four groups. The Gensini score was used to gauge the severity of coronary artery stenosis, and inflammatory biomarkers were calculated. Results: The N/SI was substantially higher in the AMI group than those in other groups, and N/SI was an independent risk factor for AMI. In ROC analyses, N/SI had the highest area under curve (AUC) for AMI among those inflammatory biomarkers. N/SI was also proved to be related with Gensini score. Conclusion: N/SI was discovered to be a new and effective inflammatory biomarker for AMI and Gensini score.

Peoples' health is at risk from heart illnesses. The indicators in patients' blood are often used to evaluate the severity of diseases. The authors collected 263 subjects with heart disease and reviewed their clinical data. Their blood was drawn to measure the neutrophil-to-serum iron ratio, a crucial blood biomarker. In conclusion, the level of neutrophil-to-serum iron ratio in these patients was closely associated with the stage and severity of their disease.

Uric acid and evaluate the coronary vascular stenosis gensini score correlation research and in gender differences.

BACKGROUND AND AIMS: Recent studies have shown that the negative effect of uric acid (UA) on coronary arteries determines the severity of atherosclerotic disease. This study aims to explore the relationship between serum UA level and Gensini score, which reflects the severity of coronary artery disease. METHODS: A total of 860 patients with suspected coronary heart disease who were admitted to hospital due to angina pectoris or myocardial ischemia related symptoms and received coronary angiography were selected. Based on the findings of the angiography, they were categorized into two groups: the coronary heart disease (CHD) group (n = 625) and the control group (n = 235). The uric acid levels and other clinical data were compared between these groups. Additionally, the prevalence of coronary heart disease and Gensini score were compared between the groups, considering gender-specific quartiles of uric acid levels. The clinical baseline data were analyzed using appropriate statistical methods, and multivariate logistic regression analysis was conducted to identify independent risk factors for coronary heart disease. RESULTS: Of 860 patients (mean age, 63.97 ± 11.87 years), 528 were men (mean age, 62.06 ± 11.5 years) and 332 were women (mean age, 66.99 ± 10.11 years). The proportion of smoking, diabetes, hypertension, and hyperlipidemia in the coronary heart disease group was higher than that in the control group (P < 0.05). HbA1C, Gensini score, BMI, TG and hsCRP in the coronary heart disease group were higher than those in the control group (P < 0.05), and HDL-C was lower than that in the control group (P < 0.05). There were no significant differences in age, heart rate, Cr, TC and LDL-C between the two groups (P > 0.05).Multivariate logistic regression analysis showed that age, hypertension, hsCRP and SUA levels increased the risk of coronary heart disease, and the difference was statistically significant(OR = 1.034,95%CI 1.016-1.052, P = 0.001; OR = 1.469,95%CI 1.007-2.142, P = 0.046;OR = 1.064,95%CI 1.026-1.105, P = 0.001; OR = 1.011,95%CI 1.008-1.014, P < 0.001). CONCLUSION: Serum uric acid is positively correlated with Gensini score in patients with coronary heart disease, which is an independent factor for evaluating the degree of coronary artery stenosis and has a predictive effect.

Genetic polymorphisms in VEGFA and VEGFR2 genes associated with coronary heart disease susceptibility and severity.

BACKGROUND: ​Vascular endothelial growth factor A (VEGFA) is well acknowledged as a powerful angiogenesis-promoting agent mainly through its receptor VEGFR2. Ischemia stimulates VEGFA/VEGFR2 signaling pathway and elevated serum levels of VEGFA were detected in coronary heart disease (CHD) patients. The goal of the current study is to determine how four SNPs in the genes for VEGFA (rs3025039 and rs699947) and VEGFR2 (rs2305948 and rs1870377) contribute to the development of CHD. We also wanted to use the Gensini score to confirm if these four SNPs have an effect on the severity of coronary lesions. METHODS: In this case-control research, we used the restriction fragment length polymorphism of the polymerase chain reaction to genotype 239 CHD patients and 200 controls. Age, sex, smoking behavior, and obesity were taken into account in the statistical analysis. RESULTS: Two VEGFA/VEFGR2 signaling pathway SNPs (rs699947 and rs1870377) were found to be associated with CHD (C vs. A, P = 0.002; OR = 1.47 (1.12-1.93); A vs. T, P = 0.001; OR = 1.58 (1.17-2.13) respectively). The rs2305948 showed no allelic associations with CHD susceptibility, although we noticed a slight association under the recessive model of rs3025039 TT genotype (p = 0.023; OR = 6.41 (1.14-36.12)) only under adjusted analyses. In addition, both VEGFA SNPs (rs699947and rs3025039) were found to be associated with high Gensini score (p < 0.001). CONCLUSIONS: Our research helps to shed further light on the pathophysiology of CHD. The VEGFA/VEGFR2 signaling pathway may have been downregulated, increasing CHD susceptibility and risk.

Relationship between serum interleukin-6 levels and severity of coronary artery disease undergoing percutaneous coronary intervention.

BACKGROUND: Cytokines play a potential role in atherosclerosis pathogenesis and progression. We investigated the association of interleukin-6 (IL-6) with the angiographic severity of coronary artery disease (CAD). METHODS: Three hundred ten angiografically diagnosed CAD patients and 210 controls were enrolled in this study. CAD patients were stratified according to IL-6 cut-off value into high levels IL-6 group (≥ 9.5 pg/mL) and low levels IL-6 group (< 9.5 pg/mL). The severity of CAD was assessed according to Gensini score (GS), artery stenosis degree and the number of vessels involved. The mean age was 60.3 ± 11.0 years. RESULTS: The level of IL-6 in patients was increased compared to controls and ranged from 1.5 to 3640.0 pg/mL. High levels of IL-6 were significantly associated with high levels of GS (> 40) but not with stenosis degree and vessel score. GS levels were significantly more elevated in patients with high levels of IL-6 group than in low IL6 levels patients (60.6 ± 39.5 vs 46.7 ± 37.2; p = 0.027). The analysis of the ROC curve performed in myocardial infarction patients showed that IL-6 (AUC: 0.941 (CI 95% 0.886, 0.997; p < 0.001) could be a powerful predictor marker in evaluating the infarct size after myocardial infarction when compared to myonecrosis biomarkers. CONCLUSIONS: IL-6 levels were associated with the severity of CAD assessed by the GS. Based on the highest levels of IL-6 measured in patients with STEMI, our study strongly suggests that IL-6 could be a powerful marker in evaluating the myocardial necrosis.

Characterizing stenosis severity of coronary heart disease by myocardial work measurement in patients with preserved ejection fraction.

Background: The novel echocardiographic parameter of myocardial work incorporates left ventricular pressure into the assessment of left ventricular systolic function and thereby corrects for afterload. We sought to investigate the diagnostic value of myocardial work to identify different grades of stenosis severity in coronary heart disease (CHD) patients with preserved left ventricular ejection fraction and without regional wall motion abnormalities. Methods: One hundred and seventeen consecutive subjects with preserved ejection fraction referred for coronary angiography were randomized and prospectively included in this study. Forty-six in the control group, and 25, 24, and 22 in each of the grade-1, grade-2, and grade-3 CHD groups as classified by the Gensini score. The following indices of myocardial work were assessed with a Vivid E95 Version 203 instrument: global work index (GWI), global constructive work (GCW), global wasted work (GWW), global work efficiency (GWE). Results: Both GWI (P<0.001) and GCW (P<0.001) decreased significantly in CHD grade-1, increased slightly in CHD grade-2 compared with CHD grade-1, and decreased significantly in CHD grade-3. GWW (P<0.001) increased significantly from CHD grade-1 to CHD grade-3, while GWE (P<0.001) decreased significantly from CHD grade-1 to CHD grade-3. Receiver operating characteristic curves analysis revealed good discrimination between the control group and CHD grade-3 for GWI [area under the curve (AUC): 0.810; 95% confidence interval (CI): 0.691-0.930], GCW (AUC: 0.758; 95% CI: 0.631-0.885), GWW (AUC: 0.754; 95% CI: 0.624-0.885) and GWE (AUC: 0.817; 95% CI: 0.709-0.926). The assessment of intraobserver and interobserver variability in the MW echocardiographic data documented good interclass correlation coefficients (all >0.85). Conclusions: Myocardial work incorporates left ventricular pressure into the assessment of left ventricular systolic function and thereby corrects for afterload. It identifies patients with incipient left ventricular dysfunction caused by chronic ischemia due to CHD. A gradual worsening of myocardial work parameters was observed when comparing patients with higher degrees of stenosis severity. Therefore, adding myocardial work when evaluating patients with suspected CHD may help increase diagnostic accuracy.

Impact of Myocardial Ischemia and Revascularization by Percutaneous Coronary Intervention on Circulating Level of Soluble ST2.

Background: The prognostic role of the soluble circulating suppression of tumorigenicity 2 marker (sST2) in different cardiovascular diseases (CVD) is still under investigation. This research aimed to assess the serum levels of sST2 in the blood of individuals with ischemic heart disease and its relation to disease severity, also to examine any changes in sST2 levels following a successful percutaneous coronary intervention (PCI) in those patients. Methods: A total of 33 ischemic patients and 30 non-ischemic controls were included. The plasma level of sST2 was measured using commercially available ELISA assay kit, at baseline and 24-48 h after the intervention in the ischemic group. Results: On admission, there was a significant difference between the group of acute/chronic coronary syndrome cases and controls regarding the sST2 plasma level (p < 0.001). There was an insignificant difference between the three ischemic subgroups at the baseline sST2 level (p = 0.38). The plasma sST2 level decreased significantly after PCI (from 20.70 ± 1.71 to 16.51 ± 2.43, p = 0.006). There was a modestly just significant positive correlation between the acute change in post-PCI sST2 level and the severity of ischemia as measured by the Modified Gensini Score (MGS) (r = 0.45, p = 0.05). In spite of the highly significant improvement in the coronary TIMI flow of ischemic group after PCI, there was insignificant negative correlation between the post- PCI delta change in the sST2 level and the post-PCI TIMI coronary flow grade. Conclusion: A significantly high plasma level of sST2 in patients with myocardial ischemia and controlled cardiovascular risk factors showed an immediate reduction after successful revascularization. The high baseline level of the sST2 marker and the acute post-PCI reduction was mainly related to the severity of ischemia rather than left ventricular function.

Correlation Analysis and Diagnostic Value of Serum Homocysteine, Cystatin C and Uric Acid Levels with the Severity of Coronary Artery Stenosis in Patients with Coronary Heart Disease.

Background: Coronary angiography (CAG) is an invasive examination with high risks and costs and various complications may occur. It is necessary to find a diagnostic method, non-invasiveness, inexpensive with low risk. This study aims to analyze the correlation between the levels of serum homocysteine (Hcy), cystatin C (Cys C) and uric acid (UA) and Gensini score in patients with coronary heart disease (CHD) and assess their diagnostic value for CHD. Methods: A retrospective analysis was conducted on 1412 patients underwent CAG from October 2019 to December 2021, and we conducted this study from January to July 2022. A total of 765 patients with CHD confirmed by CAG were selected as the research group, while 647 patients revealed as non-obstructive stenosis by CAG as the control group. The serum Hcy, Cys C and UA levels were detected and the correlation between Gensini score and variables was analyzed. The receiver-operating characteristic (ROC) curve was performed to assess the diagnostic value of the Hcy, Cys C and UA for CHD. Results: The serum Hcy, Cys C and UA levels in the research group were higher as compared with the control group (p<0.05). Spearman correlation and multivariate linear regression analysis showed that there was a significantly positive correlation between Gensini score and serum Hcy, Cys C and UA levels (p<0.05). The ROC curve analysis presented the combined Hcy and Cys C with UA having the highest specificity of diagnostic value for CHD (area under the curve (AUC)=0.768, 95% CI 0.706-0.823, specificity = 72.34%, sensitivity = 67.88%, Youden Index = 0.4022). Conclusion: The serum Hcy, Cys C and UA levels in patients with CHD were significantly increased, positive correlation with Gensini score. The combined Hcy and Cys C with UA could be used to assess the severity of coronary artery stenosis and provide predictive and early intervention treatment values for CHD and a new way of diagnosing CHD, which is cheap, safe, effective and deserving of clinical application.

Effect of Sarcopenia on Coronary Atherosclerotic Burden, Lesion Complexity, and Major Cardiovascular Events in Elderly Patients With Acute Coronary Syndrome: A 1-year Follow-up Study.

Sarcopenia is accepted as an indicator of subclinical atherosclerosis. However, its effects on clinical coronary atherosclerotic burden and lesion complexity and major adverse cardiovascular events (MACE) in elderly patients with non-ST elevation myocardial infarction (NSTEMI) are unknown. Therefore, we evaluated these possible effects. Coronary artery disease (CAD) burden and complexity were assessed using the Gensini and TAXus and cardiac surgery (SYNTAX) score, respectively. MACE involving nonfatal myocardial infarction, rehospitalization, ischemic stroke, and total mortality were evaluated after 1 year of the index NSTEMI event. The study included 240 elderly patients; of these, 60 (25%) patients had sarcopenia. The SYNTAX score and Gensini score were similar in both groups (16.8 ± 8.7 vs 17.3 ± 9.2, P = .63 and 67.7 ± 43.9 vs 73.9 ± 45.5, P = .31, respectively). The total MACE rate was significantly higher in patients with sarcopenia than in those without sarcopenia (31.7 vs 14.4%, P = .003). In the multivariate model, age [odds ratio (OR) 1.112, 95% CI: 1.006-1.228, P = .04)], ejection fraction (OR: .923, 95% CI: .897-.951, P < .001), and sarcopenia (OR: 2.262, 95% CI: 1.039-4.924, P = .04) were independently associated with MACE. Sarcopenia was independently associated with MACE but not with CAD burden or complexity in elderly patients with NSTEMI.

Role of combined use of mean platelet volume-to-lymphocyte ratio and monocyte to high-density lipoprotein cholesterol ratio in predicting patients with acute myocardial infarction.

BACKGROUND: Atherosclerosis and thrombosis play important roles in the pathophysiology of acute coronary syndrome, with platelet activation and inflammation as the key and initiative factors. Recently mean platelet volume-to-lymphocyte ratio (MPVLR) and monocyte to high-density lipoprotein cholesterol ratio (MHR) have emerged as new prognostic indicators of cardiovascular diseases. However, the predicting effect of the combination of MPVLR and MHR in myocardial infarction has not been reported. OBJECTIVE: The aim of this study was to investigate the usefulness of combination of MPVLR and MHR in predicting patients with AMI. METHODS: 375 patients who had chest pain or stuffiness were retrospectively enrolled in this study. According to the results of coronary angiography and cardiac troponin, patients were divided into AMI group (n = 284) and control group (n = 91). MPVLR, MHR, Gensini score and Grace score were calculated. RESULTS: MPVLR and MHR were significantly higher in AMI group than that in control group (6.47 (4.70-9.58) VS 4.88 (3.82-6.44), 13.56 (8.44-19.01) VS 9.14 (7.00-10.86), P < 0.001, respectively). Meanwhile, both were positively correlated with Gensini score and Grace score. Patients with a high level of MPVLR or MHR had an increased risk for AMI (odds ratio (OR) = 1.2, 95% confidence interval (CI) 1.1-1.4, OR = 1.2, 95% CI 1.2-1.3). Combination of MPVLR and MHR identified a greater ROC area than its individual parameters (P < 0.001). CONCLUSION: Both MPVLR and MHR are independent predictors of AMI. Combination of MPVLR and MHR had higher predicting value in AMI, and thus appears to be a new risk factor and biomarker in the evaluation of risk and severity of atherosclerosis in AMI.

Predictive Value of Noninvasive Peripheral Atherosclerosis Measurement for Coronary Artery Disease in Patients with Long T2DM Duration.

Objective: This study aimed to compare the predictive value of carotid or femoral artery ultrasound for coronary artery disease (CAD) in type 2 Diabetes mellitus (T2DM) patients free from known CAD, and to assess the relationship with the severity of coronary artery stenosis. Methods: Cross-sectional study in adults with a T2DM duration of at least 5 years and without established CAD. Carotid plaque score (CPS) and Gensini score were used to measure the severity of carotid and coronary artery stenosis, respectively, and patients were divided into no or mild group, moderate group, and severe group according to the tertile of the score. Univariate and multivariate logistic regression analysis was used to explore the possible risk factors for CAD. Receiver operating characteristic (ROC) curves were created to determine the most accurate assessment for detecting significant CAD (≥50% stenosis). Results: 245 patients (137 male) aged 68.21±9.5 years (range: 36-95 years), with T2DM duration 12.04± 6.17 years (range: 5-34 years), and without CVD were included. CAD was diagnosed in 165 patients (67.3%). Multiple regression analysis showed that CPS, femoral plaque, and smoking were independently and positively correlated with CAD. CPS yielded the highest area under the curve for detecting significant coronary disease (AUC=0.7323). In contrast, the area under the curve of femoral artery plaque and carotid intima-media thickness was lower than 0.7, which was at a lower prediction level. Conclusion: In patients with long T2DM duration, CPS has a higher ability to predict the occurrence and severity of CAD. However, femoral artery plaque has special value in predicting moderate to severe coronary artery disease in patients with long-term T2DM.

Earlobe Creases as a Marker of the Risk for Coronary Atherosclerosis Before Angiography in Elderly and Non-elderly Patients.

Background The close relationship between earlobe creases (ELC) and the presence of coronary artery disease (CAD) has been reported. In addition, this study aimed to determine associations between ELC and the presence, extent, and severity of coronary atherosclerosis assessed by coronary angiography in non-elderly and elderly patients. Methods We assessed 1,086 consecutive patients with suspected CAD by coronary angiography. We defined severe CAD as Gensini scores > 20. Multiple logistic regression analysis was adjusted for age, sex, hypertension, diabetes mellitus, smoking status, lipid profiles, and body mass index (BMI) to assess the presence or absence of CAD, multivessel disease, and severe CAD in elderly (age ≥ 60 years) and non-elderly (age < 60 years) patients. Results ELC was a significantly positive determinant of CAD (odds ratio (OR) = 3.074, p < 0.001), multivessel disease (OR = 3.101, p < 0.001), and severe CAD (OR = 2.823, p < 0.001) in all patients. ELC was also a predictor of CAD, multivessel disease, and severe CAD not only in patients aged ≥ 60 years (OR = 3.095, p < 0.001; OR = 3.071, p < 0.001; OR = 2.761, p < 0.001, respectively) but also in those aged < 60 years (OR = 2.749, p = 0.035; OR = 2.634, p = 0.038; OR = 2.766, p = 0.006, respectively). Conclusions ELC was independently associated with the presence of CAD, multivessel disease, and severe CAD in both elderly and non-elderly patients who were assessed by coronary angiography.

Association Between Major Adverse Cardiovascular Events and the Gensini Score or Coronary Artery Calcification Score in Hypertensive Patients Who Have Undergone Coronary Computed Tomography Angiography.

Background: From the Fukuoka University Coronary Computed Tomography Angiography (FU-CCTA) registry, we present major adverse cardiovascular events (MACEs) in hypertensive patients who have undergone CCTA, and the association between MACEs and the Gensini score of coronary arteries or the coronary artery calcification (CAC) score. Methods: Of the patients who underwent CCTA for coronary artery disease (CAD) screening at Fukuoka University Hospital, 318 hypertensive patients who had at least one cardiovascular risk factor or suspected CAD were enrolled. The patients were divided into two groups: MACEs and non-MACEs groups. The severity of atherosclerosis of coronary arteries was assessed by the Gensini score. The CAC score was also defined by computed tomography (CT) images at the time of CCTA. A primary endpoint was MACEs (all-cause death, ischemic stroke, acute myocardial infarction, coronary revascularization). The patients were followed for up to 5 years. Results: The patients were 68 ± 10 years, and 50% were males. The percentages of smoking, dyslipidemia, diabetes, and chronic kidney disease were 39%, 70%, 26% and 37%, respectively. The %males, %smoking, CAC score and Gensini score in the MACEs group were significantly higher than those in the non-MACEs group. On the other hand, the differences in age, dyslipidemia, diabetes, or chronic kidney disease between the groups were not seen. A multivariate analysis was performed regarding the presence or absence of MACE by logistic regression analysis of the CAC score or Gensini score in addition to conventional risk factors as independent variables. A Cox regression analysis revealed significant relationships for both the CAC score (P = 0.043) and the Gensini score (P = 0.008). Conclusions: The CAC score and the Gensini score could predict MACEs in hypertensive patients who have undergone CCTA.

Prognostic value of gut microbiota-derived metabolites in patients with ST-segment elevation myocardial infarction.

BACKGROUND: Studies about the prognostic role of gut microbiota-derived metabolites including phenylacetyl glutamine (PAGln), indoxyl sulfate (IS), lithocholic acid (LCA), deoxycholic acid (DCA), trimethylamine (TMA), trimethylamine N-oxide (TMAO), and its precursor trimethyllysine (TML) are limited in patients with ST-segment elevation myocardial infarction (STEMI). OBJECTIVES: To examine the relationship between plasma metabolite levels and major adverse cardiovascular events (MACEs), including nonfatal MI, nonfatal stroke, all-cause mortality, and heart failure in patients with STEMI. METHODS: We enrolled 1004 patients with STEMI undergoing percutaneous coronary intervention (PCI). Plasma levels of these metabolites were determined by targeted liquid chromatography/mass spectrometry. The associations of metabolite levels with MACEs were assessed with the Cox regression model and quantile g-computation. RESULTS: During a median follow-up of 360 d, 102 patients experienced MACEs. Higher plasma PAGln (hazard ratio [HR], 3.17 [95% CI: 2.05, 4.89]; P < 0.001), IS (2.67 [1.68, 4.24], P < 0.001), DCA (2.36 [1.40, 4.00], P = 0.001), TML (2.66 [1.77,3.99], P < 0.001), and TMAO (2.61 [1.70, 4.00], P < 0.001) levels were significantly associated with MACEs independent of traditional risk factors. According to quantile g-computation, the joint effect of all these metabolites was 1.86 (95% CI: 1.46, 2.27). PAGln, IS and TML had the greatest proportional positive contributions to the mixture effect. Additionally, plasma PAGln and TML combined with coronary angiography scores including the Synergy between PCI with Taxus and cardiac surgery (SYNTAX) score (area under the curve [AUC]: 0.792 vs. 0.673), Gensini score (0.794 vs. 0.647) and Balloon pump-assisted Coronary Intervention Study (BCIS-1) jeopardy score (0.774 vs. 0.573) showed better prediction performance for MACEs. CONCLUSIONS: Higher plasma PAGln, IS, DCA, TML, and TMAO levels are independently associated with MACEs suggesting that these metabolites may be useful markers for prognosis in patients with STEMI.

Severity of Coronary Artery Diseases Among Pre- and Postmenopausal Women With Acute Coronary Syndrome: A Hospital-Based Study in Bangladesh.

BACKGROUND: Postmenopausal women present with more severe coronary artery disease (CAD) in addition to multiple comorbidities. However, there are limited data available to compare the risk factors, clinical characteristics, and angiographic severity of CAD between pre- and postmenopausal women with the acute coronary syndrome (ACS). AIM: This study aimed to assess and compare the severity of CAD in pre- and postmenopausal women with ACS. METHODS: This cross-sectional observational study was conducted at the Department of Cardiology of NHFH RI. A total of 140 female patients with ACS were enrolled and then divided into Group I (premenopausal) and Group II (postmenopausal) on the basis of menopause history. Clinical data and coronary angiographic severity were compared between both groups. RESULTS: The mean age of the premenopausal group was 41.53 ± 5.45 years, and that of the postmenopausal group was 57.23 ± 7.45 years. Family history of premature CAD was significantly more common in the premenopausal group than in the postmenopausal group (35(50%) vs. 23(32.9%); p=0.017)). DM and smokeless tobacco were more prevalent in the postmenopausal group (48(68.6%) vs. 28(40%); p=0.001 and 14(20%) vs. 2(2.9%); p=0.002). Atypical presentation was more common in the premenopausal group (21(30%) vs. 9(12.9%); p=0.013). Most of the patients in both groups presented with unstable angina followed by NSTEMI and STEMI. Mean left ventricular ejection fraction was lower in the postmenopausal group than in the premenopausal group (50.71 ± 8.38% vs. 53.74 ± 7.46%; p=0.026). Normal coronary angiogram and single-vessel disease were more prevalent in the premenopausal group (22(31.4%) vs. 12(17.1%); p=0.04) and (22(31.4%) vs. 11(15.7%); p=0.002), whereas triple-vessel disease was more prevalent in the postmenopausal group (34(48.6% vs. 14(20%); p=0.001). The left anterior descending artery was the most commonly involved vessel in the postmenopausal group (67(95.7%) vs. 60(85.7%); p=0.04). Finally, the mean Gensini score was higher in the postmenopausal group than in the premenopausal group (56.1 ± 43.4 vs. 33.5 ± 36.9; p=0.001). CONCLUSION: Family history of premature CAD and atypical presentation were common in premenopausal ACS patients. DM and smokeless tobacco use were more prevalent in the postmenopausal group than in the premenopausal group. Normal coronary angiogram and single-vessel disease were more prevalent in the premenopausal group, and triple-vessel disease was more common in the postmenopausal group. CAD was more severe in the postmenopausal group.

Blood group B and decreased risk of coronary artery disease in hypertensive elderly / Grupo sanguíneo B y disminución del riesgo de enfermedad arterial coronaria en ancianos hipertensos

Abstract Although ABO blood groups have been associated with cardiovascular disease, little is known about whether ABO blood groups contribute to the risk of the presence and severity of coronary artery disease (CAD) in elderly individuals with hypertension. This study was aimed to explore this association. A total of 793 hypertensive patients aged ≥60 years out of 2095 patients who underwent primary coronary angiography were retrospectively included. They were divided into CAD and non-CAD groups. Demographic and clinical characteristics, ABO blood groups and other biochemical parameters were compared. Further evaluation was performed to determine the impact of ABO blood groups on CAD severity using the Gensini score and the number of significantly diseased vessels. A logistic regression model was constructed to identify the association of ABO blood groups with CAD. There was a substantial difference in the distribution of ABO blood groups in elderly and hypertensive adults with and without CAD (p=0.022). Hypertensive patients with CAD had a significantly lower proportion of the blood group B than those without CAD (p=0.008). Compared to those with non-Blood group B, hypertensive elderly with a blood group B tended to have significantly lower concentrations of TC, LDL -C and Apo B, and a lower number of significantly stenosed vessels. The blood group B was found to be an independent protective factor for CAD in elderly with hypertension. The blood group B is significantly associated with a decreased risk of CAD and is inversely correlated with the severity of coronary stenosis in the elderly with hypertension.

Resumen Aunque los tipos de sangre ABO están asociados con enfermedades cardiovasculares, se sabe poco sobre si los tipos de sangre ABO estás relacionados con la presencia y gravedad de la enfermedad arterial coronaria (CAD) en pacientes de edad avanzada con hipertensión. El objetivo de este estudio fue explorar esta relación. Se incluyeron retrospectivamente un total de 793 pacientes hipertensos de ≥60 años tomados de un grupo de 2095 pacientes sometidos a angiografía coronaria primaria. Se dividieron en el grupo de cardiopatía coronaria (CAD) y el grupo sin cardiopatía coronaria (no-CAD). Se compararon las características demográficas y clínicas, el grupo sanguíneo ABO y otros parámetros bioquímicos. El efecto del grupo sanguíneo ABO sobre la gravedad de la CAD se evaluó con la puntuación Gensini y el número de vasos sanguíneos patológicos significativos. Se construyó un modelo de regresión logística para determinar la relación entre el grupo sanguíneo ABO y la CAD. Hubo una diferencia significativa en la distribución de los grupos sanguíneos ABO entre los ancianos con y sin cardiopatía coronaria y los adultos con hipertensión (P=0,022). La proporción del grupo sanguíneo B en pacientes hipertensos con cardiopatía coronaria fue significativamente menor que en pacientes sin cardiopatía coronaria (P=0,008). En comparación con los grupos sanguíneos no B, las concentraciones de TC, LDL - C y Apolipoproteína B en los ancianos hipertensos del Grupo B fueron significativamente menores, y el número de estenosis vascular fue significativamente menor. El Grupo B es un factor protector independiente de la CAD en pacientes de edad avanzada con hipertensión. El Grupo B se correlacionó significativamente con la reducción del riesgo de cardiopatía coronaria y negativamente con la gravedad de la estenosis coronaria en pacientes de edad avanzada con hipertensión.
