Lipidomic Analysis to Assess the Correlation between Ceramides, Stress Hyperglycemia, and HbA1c in Acute Myocardial Infarction. MOLECULES (BASEL, SWITZERLAND) 2023; 28:molecules28020716. [PMID: 36677773 PMCID: PMC9862855 DOI: 10.3390/molecules28020716] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 12/14/2022] [Revised: 12/30/2022] [Accepted: 12/31/2022] [Indexed: 01/13/2023]
Abstract
Ceramides have been associated with cardiometabolic disease (e.g., acute myocardial infarction (AMI) and type 2 diabetes (T2D)) and adverse outcomes. Acute admission hyperglycemia (AH) is a transient glucose alteration in response to stress. As glycated hemoglobin (HbA1c) reflects the glycemia over a longer period of time, its use may be helpful in distinguishing between the AH and hyperglycemia associated with T2D in the AMI setting. The aim was to assess the correlation of ceramides with both AH (defined as an admission glucose level ≥140 mg/dL in the absence of T2D) and HbA1c-T2D and other demographic, clinical, and inflammatory-related biomarkers in AMI. High-performance liquid chromatography-tandem mass spectrometry was used to identify nine ceramide species, and their three ratios, in 140 AMI patients (FTGM coronary unit, Massa, Italy). The ceramides did not correlate with stress hyperglycemia, but specific species were elevated in T2D-AMI. Moreover, some ceramides were associated with other cardiometabolic risk factors. Ceramides assessment may be helpful in better understanding the pathogenic molecular mechanisms underlying myocardial acute events and cardiometabolic risk, as a basis for the future evaluation of their role as prognostic predictors and therapeutic targets in T2D-AMI patients.

METTL3-modified lncRNA-SNHG8 binds to PTBP1 to regulate ALAS2 expression to increase oxidative stress and promote myocardial infarction. Mol Cell Biochem 2022; 478:1217-1229. [PMID: 36282350 DOI: 10.1007/s11010-022-04570-6] [Citation(s) in RCA: 14] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/17/2022] [Accepted: 09/16/2022] [Indexed: 10/31/2022]
Abstract
Myocardial infarction (MI) is one of the important factors leading to death in today's society. Therefore, to study the related mechanism of MI and reduce myocardial ischemia-reperfusion injury is an important link to reduce MI injury. MI mice in vivo and cell model in vitro were constructed. The cardiac function and MI area of mice were detected, and myocardial tissue injury was detected by HE staining. ALAS2 expression in mice myocardial tissue was detected by IHC. The expressions of lncRNA-SNHG8, METTL3, PTBP1 and ALAS2 in myocardial tissue or cardiomyocytes were detected by qRT-PCR assay. MTT assay was used to measured viability of cardiomyocytes. The oxidative stress level in myocardial tissue or cardiomyocytes was detected by ELISA assay and ROS assay. RIP-qPCR and RNA pulldown assays determined the interaction between METTL3 and lncRNA-SNHG8, as well as PTBP1 and ALAS2. lncRNA-SNHG8 knockdown in MI mice was reduced myocardial infarction size, alleviated myocardial tissue injury and oxidative stress, and inhibited ALAS2 expression in myocardial tissue. RNA pulldown and RIP assays showed that lncRNA-SNHG8 binged with PTBP1 and PTBP1 interacted with ALAS2 mRNA. Knockdown of lncRNA-SNHG8, METTL3 or PTBP1 in MI cells enhanced viability of myocardial cells, attenuated ROS release and MDA level, increased SOD level, alleviated oxidative stress. ALAS overexpression attenuated the corresponding effect of knockdown of lncRNA-SNHG8 and/or PTBP1 on MI cells. In sum, our paper is demonstrated for the first time that METTL3 can promote lncRNA-SNHG8 through m6A modification, thereby regulating ALAS2 to induce oxidative stress and aggravate myocardial injury.

Postgrad Med J 2022:7148071.

Abstract
BACKGROUND The optimal threshold of hyperglycaemia at admission for identifying high-risk individuals in patients with acute myocardial infarction (AMI) and its impact on clinical prognosis are still unclear. METHODS We retrospectively reviewed 2027 patients with AMI admitted from June 2001 to December 2012 in the 'Medical Information Mart for Intensive Care III' database. The significant cut-off values of admission blood glucose (Glucose_0) for predicting hospital mortality in patients with AMI with and without diabetes were obtained from the receiver operating characteristic (ROC) curve, then patients were assigned to hyperglycaemia and non-hyperglycaemia groups based on corresponding cut-off values. The primary endpoints were the hospital and 1-year mortality. RESULTS Among 2027 patients, death occurred in 311 patients (15.3%). According to the ROC curve, the significant cut-off values of Glucose_0 to predict hospital mortality were 224.5 and 139.5 mg/dL in patients with diabetes and without diabetes, respectively. The crude hospital and 1-year mortality of the hyperglycaemia subgroup were higher than the corresponding non-hyperglycaemia group (p< 0.01). After adjustment, regardless of the state of diabetes, hyperglycaemia at admission was related to significantly increased hospital mortality in patients with AMI. For patients with AMI without diabetes, hyperglycaemia at admission was positively correlated with the increase of 1-year mortality (HR, 1.47; 95% CI 1.18 to 1.82; p=0.001). Nevertheless, this trend disappeared in those with diabetes (HR, 1.35; 95% CI 0.93 to 1.95; p=0.113). CONCLUSION Hyperglycaemia at admission was an independent predictor for mortality during hospitalisation and at 1-year in patients with AMI, especially in patients without diabetes.

Association of admission hyperglycemia and all-cause mortality in acute myocardial infarction with percutaneous coronary intervention: A dose–response meta-analysis. Front Cardiovasc Med 2022; 9:932716. [PMID: 36172574 PMCID: PMC9510712 DOI: 10.3389/fcvm.2022.932716] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/30/2022] [Accepted: 07/25/2022] [Indexed: 01/08/2023] Open
Abstract
Objective The aim of this study is to evaluate the associations between admission hyperglycemia and the risk of all-cause mortality in patients with acute myocardial infarction (AMI) with or without diabetes, to find optimal admission glucose intervention cut-offs, and to clarify the shape of the dose–response relations. Methods Medline/PubMed and EMBASE were searched from inception to 1 April 2022. Cohort studies reporting estimates of all-cause mortality risk in patients with admission hyperglycemia with AMI were included. The outcomes of interest include mortality and major adverse cardiac events (MACEs). A random effect dose–response meta-analysis was conducted to access linear trend estimations. A one-stage linear mixed effect meta-analysis was used for estimating dose–response curves. Relative risks and 95% confidence intervals were pooled using a random-effects model. Results Of 1,222 studies screened, 47 full texts were fully reviewed for eligibility. The final analyses consisted of 23 cohort studies with 47,177 participants. In short-term follow-up, admission hyperglycemia was associated with an increased risk of all-cause mortality (relative risk: 3.12, 95% confidence interval 2.42–4.02) and MACEs (2.34, 1.77–3.09). In long-term follow-up, admission hyperglycemia was associated with an increased risk of all-cause mortality (1.97, 1.61–2.41) and MACEs (1.95, 1.21–3.14). A linear dose–response association was found between admission hyperglycemia and the risk of all-cause mortality in patients with or without diabetes. Conclusion Admission hyperglycemia was significantly associated with higher all-cause mortality risk and rates of MACEs. However, the association between admission hyperglycemia and long-term mortality risk needs to be determined with caution. Compared with current guidelines recommendations, a lower intervention cut-off and more stringent targets for admission hyperglycemia may be appropriate.

Abstract
BACKGROUND It is uncertain whether the effect of hyperglycemia on mortality among patients with acute coronary syndrome (ACS) could be adjusted by other modifiable risk factors. Greater body mass index (BMI) might enhance the effect of fasting blood glucose (FPG) on cardiovascular mortality in patients with ACS. METHODS We retrospectively enrolled patients admitted for ACS from 2008 to 2017 in Beijing and divided them into three BMI groups (normal weight ≤ 25 kg/m2, overweight 25-29.9 kg/m2, obese ≥ 30 kg/m2). The relationships between the blood glucose levels and all-cause or cardiovascular mortalities and their heterogeneities across the groups were analyzed using Cox regression models. RESULTS A total of 8,086 patients were enrolled, with 746 all-cause and 496 cardiovascular mortalities recorded during the follow-up period. Each 1 mmol/L increase in FPG was associated with an increased risk of all-cause mortality across all groups (adjusted hazard ratio [HR] 1.06, 95% confidence interval [CI] 1.02-1.09 for normal weight patients; adjusted HR: 1.09, 95% CI: 1.05-1.13 for overweight patients; adjusted HR: 1.12, 95% CI: 1.03-1.22 for obese patients), and was associated with an increased risk of cardiovascular mortality among overweight (adjusted HR: 1.10, 95% CI: 1.05-1.14) and obese patients (adjusted HR: 1.15, 95% CI: 1.04-1.26), which was greater (p for heterogeneity = 0.006) than the association in the normal weight group (adjusted HR: 1.03, 95% CI: 0.99-1.08). Similar results were found among 2,537 patients with ACS diagnosed with diabetes. CONCLUSION Greater BMI enhances the effect of FPG on cardiovascular mortality among patients with ACS.

Abstract
BACKGROUND Admission hyperglycemia (AH) is a common finding in patients with acute coronary syndrome and has been reported to be associated with increased morbidity and mortality. Prior studies suggest that AH could be associated with reperfusion failure. We conducted a systematic review and meta-analysis to explore an association between AH and risk of reperfusion failure in patients with ST-elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (pPCI). METHODS Two investigators searched the databases of MEDLINE and EMBASE from inception to February 2021. Study eligibility was independently determined by two investigators and needed to demonstrate association of AH and rate of reperfusion failure, or sufficient raw data to calculate the effect size. Participants were classified into two groups corresponding to their level of admission hyperglycemia. Group 1 was defined as an AH of ≥120-150 mg/dl, and group 2 as ≥150-200 mg/dl. Data from each study were combined using the random-effects model, the generic inverse-variance method of Der Simonian and Laird. The heterogeneity of effect size was quantified using the I2 statistic. A sensitivity analysis was performed by omitting one study at a time. Publication bias was assessed using a funnel plot and the Egger's test. All data analyses were performed using STATA SE version 14.2. RESULTS A total of ten studies from 2008 to 2019 met eligibility criteria and were included in the final analysis. We found that AH is associated with increased risk of reperfusion failure in both group 1 (pooled OR=1.78, 95% CI: 1.35-2.33, I2=63.2%, P<0.001) and group 2 (pooled OR=1.44, 95% CI: 1.14-1.82, I2=57.1%, P<0.001). Sensitivity analysis showed that none of the results were significantly altered after removing one study at a time. In subgroup analysis of non-diabetic patients, we found that AH is also associated with increased risk of reperfusion failure in both group 1 (pooled OR=1.81, 95% CI: 1.29-2.54, P<0.001) and group 2 (pooled OR=1.61, 95% CI: 1.17-2.21, P<0.001). We did not perform a funnel plot or Egger's test as the number of available outcomes was insufficient to reject the assumption of funnel plot asymmetry. CONCLUSIONS Our systematic review and meta-analysis demonstrated that AH is associated with increased risk of reperfusion failure in STEMI patients undergoing pPCI, in the non-diabetic population.

Abstract
In patients with acute myocardial infarction, glucose metabolism is altered and acute hyperglycemia on admission is common regardless of diabetes status. The development of coronary collateral is heterogeneous among individuals with coronary artery disease. In this study, we aimed to investigate whether glucose value on admission is associated with collateral flow in ST-elevation myocardial infarction (STEMI) patients. We retrospectively evaluated 190 consecutive patients with a diagnosis of first STEMI within 12 hours of onset of chest pain. Coronary collateral development was graded according to Rentrop classification. Rentrop 0-1 was graded as poor collateral development, and Rentrop 2-3 was graded as good collateral development. Admission glucose was measured and compared between two groups. Mean admission glucose level was 173.0 ± 80.1 mg/dl in study population. Forty-five (23.7%) patients had good collateral development, and 145 (76.3%) patients had poor collateral development. There were no statistically significant differences in demographic characteristics between two groups. Three-vessel disease was more common in patients with good collateral development (p=0.026). Mean admission glucose level was higher in patients with poor collateral than good collateral (180.6 ± 84.9 mg/dl versus 148.7 ± 56.6 mg/dl, resp., p=0.008). In univariate analysis, higher admission glucose was associated with poor collateral development, but multivariate logistic regression analysis revealed a borderline result (odds ratio 0.994, 95% CI 0.989-1.000, p=0.049). Our results suggest that elevated glucose on admission may have a role in the attenuation of coronary collateral blood flow in acute myocardial infarction. Further studies are needed to validate our results.

Abstract
OBJECTIVE Hyperglycemia on admission and during hospital stay is a well-established predictor of short-term and long-term mortality in patients with acute myocardial infarction. Our study investigated the impact of blood glucose levels on admission and in-hospital hyperglycemia on the morbidity and mortality of Libyan patients admitted with acute coronary syndromes (acute myocardial infarction and unstable angina). METHODS In this retrospective study, the records of patients admitted with acute coronary syndrome to The 7th Of October Hospital, Benghazi, Libya, between January 2011 and December 2011 were reviewed. The level of blood glucose on admission, and the average blood glucose during the hospital stay were recorded to determine their effects on in-hospital complications (e.g. cardiogenic shock, acute heart failure, arrhythmias, and/or heart block) and mortality. RESULTS During the study period, 121 patients with diabetes were admitted with acute coronary syndrome. The mortality rate in patients with diabetes and acute coronary syndrome was 12.4%. Patients with a mean glucose level greater than 200mg/dL had a higher in-hospital mortality and a higher rate of complications than those with a mean glucose level ≤200mg/dL (27.5% vs. 2.6%, p<0.001 and 19.7% vs. 45.5%, p=0.004, respectively). There was no difference in in-hospital mortality between patients with a glucose level at admission ≤140mg/dL and those admitted with a glucose level >140mg/dL (6.9% vs. 14.3%; p=0.295), but the rate of complications was higher in the latter group (13.8% vs. 34.1%; p=0.036). Patients with admission glucose levels >140mg/dL also had a higher rate of complications at presentation (26.4% vs. 6.9%; p=0.027). CONCLUSION In patients with diabetes and acute coronary syndrome, hyperglycemia during hospitalization predicted a worse outcome in terms of the rates of in-hospital complications and in-hospital mortality. Hyperglycemia at the time of admission was also associated with higher rate of complications particularly at the time of presentation.

Abstract
OBJECTIVE The aim of this analysis was to assess the association between elevated blood glucose level and mortality in acute heart failure (AHF). BACKGROUND Elevated blood glucose has been reported to be prognostically meaningful in patients with cardiac diagnoses, such as coronary artery disease. The short-term prognostic impact of hyperglycemia in AHF is unknown, however. METHODS In a multinational cohort of AHF, we examined the ability of blood glucose concentrations at presentation to predict all-cause mortality by 30 days. Fully adjusted models for prognosis included a previous diagnosis of diabetes mellitus as a covariate. RESULTS A total of 6,212 subjects with AHF (mean age, 72 years; 52.5% male) were studied; the median blood glucose concentration on arrival at the hospital was 7.5 mmol/l (135 mg/dl), and 41% had a previous diagnosis of diabetes mellitus (DM). After 30 days, 618 patients (10%) had died. Compared with survivors, decedents had significantly higher median blood glucose concentrations (8.9 mmol/l vs. 7.4 mmol/l; p < 0.0001). In the fully adjusted model, an elevated blood glucose level was an independent predictor of 30-day mortality in AHF (odds ratio: 2.19; 95% confidence interval: 1.69 to 2.83; p < 0.001). The risk associated with an elevated blood glucose level appeared consistent across all subgroups of patients, including patients with preserved (hazard ratio: 5.41; 95% confidence interval: 2.44 to 12.0; p < 0.0001) and impaired systolic function (hazard ratio: 2.37; 95% confidence interval: 1.57 to 3.59; p < 0.0001). Furthermore, in reclassification analyses, elevated blood glucose added significant prognostic information to clinical parameters alone (4.4% net reclassification improvement; p = 0.01). CONCLUSIONS Among patients with AHF, blood glucose concentrations at presentation are powerfully prognostic for 30-day mortality, independent of a diagnosis of diabetes mellitus or other clinical variables. Because blood glucose is easily modifiable, it may represent a valid target for therapeutic intervention.
