Abstract
BACKGROUND Imatinib treatment for certain cancers can lead to elevated creatine kinase (CK) levels, potentially indicating muscle injury, and ongoing research aims to understand the correlation between imatinib levels and creatine kinase to assess its impact on treatment response. METHODS This single-center observational study involved 76 chronic myeloid leukemia (CML) patients receiving imatinib treatment, focusing on evaluating drug and metabolite levels using liquid chromatography-mass spectrometry (LC-MS-MS) instrumentation. Serum CK and creatine kinase-MB (CK-MB) levels were assessed using Colorimetric kits. RESULTS CK and CK-MB levels were measured, CK showed a median value of 211.5 IU/l and CK-MB showed a median value of 4.4 IU/l. Comparing low and high CK groups, significant differences were found in peak and trough plasma concentrations of imatinib and its metabolites. Correlations between CK levels and pharmacokinetic parameters were explored, with notable associations identified. Binary logistic regression revealed predictors influencing the therapeutic response to imatinib and categorized expected CK levels into high or low, with peak levels of imatinib emerging as a significant predictor for CK level categorization. CONCLUSION The study highlights the link between imatinib's pharmacokinetics and elevated CK levels, indicating a possible correlation between specific metabolites and improved treatment response. Individualized monitoring of CK levels and imatinib pharmacokinetics could enhance care for CML patients.

Abstract
OBJECTIVE The objective of this study was to investigate the impact of Doxorubicin, Epirubicin, and Liposomal Doxorubicin (Anthracycline) on cardiac function in osteosarcoma patients and analyze the factors influencing this effect. METHODS A retrospective study was conducted on 165 osteosarcoma patients admitted to our hospital from January 2020 to December 2022. Based on the chemotherapy regimen, the patients were divided into two groups: the control group (n = 62) treated with Cisplatin and cyclophosphamide, and the observation group (n = 103) treated with Doxorubicin, Epirubicin, and Liposomal Doxorubicin (Anthracycline). The general records of both groups were analyzed, and left ventricular ejection fraction (LVEF) was evaluated through echocardiography before and after chemotherapy. Blood cTnT and CK-MB levels were measured using immunoluminescence. The incidence of adverse reactions during chemotherapy was also analyzed. Univariate analysis was performed to identify patients with cardiotoxic events, and multiple logistic regression analysis was done to study the effects of Doxorubicin, Epirubicin, Liposomal Doxorubicin, and their dosages on cardiotoxicity in patients. RESULTS The general records between the two groups showed no significant differences (P > 0.05). However, at the fourth cycle of chemotherapy, the observation group exhibited a lower LVEF (P < 0.05), and a higher percentage of LVEF decrease compared to the control group (P < 0.05). Moreover, the observation group had higher levels of blood cTnT and CK-MB (P < 0.05). The incidence of cardiotoxicity in the observation group was also higher (P < 0.05), but no significant differences were seen in other adverse reaction rates (P > 0.05). The occurrence of cardiotoxicity was found to be related to the choice and dosage of chemotherapy drugs (P < 0.05), but not significantly correlated with age, sex, and mediastinal irradiation in patients (P > 0.05). Furthermore, the use of Doxorubicin, Epirubicin, and Liposomal Doxorubicin in chemotherapy, as well as an increase in their dosages, was found to elevate the risk of cardiotoxicity in osteosarcoma patients (P < 0.05). However, age, sex, and mediastinal radiation were not significantly associated with cardiotoxicity in osteosarcoma patients (P > 0.05). CONCLUSION We demonstrated that Doxorubicin, Epirubicin, Liposomal Doxorubicin (Anthracycline), and other drugs adversely affected cardiac function in osteosarcoma patients, increasing the risk of cardiac toxicity. Therefore, close monitoring of cardiac function during chemotherapy is crucial, and timely adjustments to the chemotherapy regimen are necessary. In addition, rational control of drug selection and dosage is essential to minimize the occurrence of cardiac toxicity.

Abstract
Objective To assess cardiac troponin I and creatine kinase-myocardial band levels, electrocardiogram changes and major adverse cardiac events after treatment with nicorandil before primary percutaneous coronary intervention. METHODS The comparative, analytical study was conducted from October to November 2022 at the Pharmacology Department of Army Medical College, National University of Medical Sciences, Rawalpindi, Pakistan, in collaboration with the Rawalpindi Institute of Cardiology, Rawalpindi. The sample comprised ST-elevated myocardial infarction patients of either gender aged at least 30 years with an ejection fraction of at least 35% undergoing primary percutaneous coronary intervention. Participants were selected based on the above-mentioned inclusion and informed consent was taken before their enrolment in this research study. The sample was randomised into control group A receiving conventional acute coronary syndrome treatment, and intervention group B receiving nicorandil in addition to the conventional treatment. Cardiac troponin I and creatine kinase-myocardial band levels, electrocardiogram changes, and major adverse cardiac events noted and compared. Data was analysed using SPSS 26. RESULTS Of the 140 patients, 70(50%) were in each of the 2 groups. In group B, 60(85.7%) patients achieved a completely settled ST segment on electrocardiogram compared to 25(35.7%) in group A (p=0.001). There was a significant inter-group difference with respect to cardiac troponin I value 6 hours after percutaneous coronary intervention and major adverse cardiac events (p<0.05), but creatine kinase-myocardial band level was no significantly different between the groups (p=0.761). Conclusion Prophylactic use of nicorandil in ST-elevated myocardial infarction patients decreased the incidence of reperfusion injury.

Abstract
BACKGROUND Over the past decade, immune checkpoint inhibitors (ICIs) have significantly transformed cancer treatment. However, ICIs inevitably may cause a spectrum of immune-related adverse events, among which cardiovascular toxicity, particularly myocarditis, while infrequent, has garnered increasing attention due to its high fatality rate. METHODS We conducted a multicenter retrospective study to characterize ICI-associated cardiovascular adverse events. Logistic regression was performed to explore the risk factors for the development of myocarditis and severe myocarditis. Receiver operating characteristic curves were conducted to assess the diagnostic abilities of cardiac biomarkers to distinguish different cardiovascular toxicities, and the performance and calibration were evaluated using Hosmer-Lemeshow test. RESULTS Forty-four patients were identified, including thirty-five myocarditis, five heart failure, three arrhythmias, and one myocardial infarction. Compared with other patients, myocarditis patients had higher cardiac troponin-I (cTnI) levels (p < 0.001), higher creatine kinase levels (p = 0.003), higher creatine kinase isoenzyme-MB (CK-MB) levels (p = 0.013), and shorter time to the incidence of adverse cardiovascular events (p = 0.022) after ICI treatment. Twenty-one patients (60%) were classified as severe myocarditis, and they presented higher cardiac troponin I (cTnI) levels (p = 0.013), higher N-terminal pro-B-type natriuretic peptide levels (p = 0.031), higher creatine kinase levels (p = 0.018), higher CK-MB levels (p = 0.026), and higher neutrophil to lymphocyte ratio (NLR) levels (p = 0.016) compared to non-severe myocarditis patients after ICI treatment. Multivariate logistic regression showed that CK-MB (adjusted odds ratio [OR]: 1.775, 95% confidence interval [CI]: 1.055-2.984, p = 0.031) was the independent risk factor of the development of ICI-associated myocarditis, and cTnI (adjusted OR: 1.021, 95% CI: 1.002-1.039, p = 0.03) and NLR (adjusted OR: 1.890, 95% CI: 1.026-3.483, p = 0.041) were the independent risk factors of ICI-associated severe myocarditis. The receiver operating characteristic curve showed an area under curve of 0.785 (95% CI: 0.642 to 0.928, p = 0.013) for CK-MB, 0.765 (95% CI: 0.601 to 0.929, p = 0.013) for cTnI, and 0.773 for NLR (95% CI: 0.597 to 0.948, p = 0.016). CONCLUSIONS Elevated CK-MB after ICI treatment is the independent risk factor for the incidence of ICI-associated myocarditis, and elevated cTnI and NLR after ICI treatment are the independent risk factors for the development of ICI-associated severe myocarditis. CK-MB, cTnI, and NLR demonstrated a promising predictive utility for the identification of ICI-associated myocarditis and severe myocarditis.

Abstract
OBJECTIVES This study aimed to evaluate the prognostic significance of postoperative Creatine Kinase type M and B (CK-MB) to total Creatine Kinase (CK) ratio (CK-MB/CK) in colorectal cancer (CRC) patients after radical resection. METHODS This was a single-center retrospective cohort analysis. Subjects were stage I-III CRC patients hospitalized in Sichuan Cancer Hospital from January 2017 to May 2021. Patients were divided into abnormal group and normal group according to whether the CK-MB/CK ratio was abnormal after surgery. Through a comparative analysis of clinical data, laboratory test results, and prognosis differences between the two groups, we aimed to uncover the potential relationship between abnormal CK-MB > CK results and CRC patients. To gauge the impact of CK-MB/CK on overall survival (OS) and disease-free survival (DFS), we employed the multivariable COX regression and LASSO regression analysis. Additionally, Spearman correlation analysis, logistic regression, and receiver-operating characteristic (ROC) curve analysis were conducted to assess the predictive value of the CK-MB/CK ratio for postoperative liver metastasis. RESULTS Cox regression analysis revealed that the CK-MB/CK ratio was a stable risk factors for OS (HR = 3.82, p < 0.001) and DFS (HR = 2.31, p < 0.001). To distinguish hepatic metastases after surgery, the ROC area under the curve of CK-MB/CK was 0.697 (p < 0.001), and the optimal cut-off value determined by the Youden index was 0.347. CONCLUSIONS Postoperative abnormal CK-MB/CK ratio predicts worse prognosis in CRC patients after radical resection and serves as a useful biomarker for detecting postoperative liver metastasis.

Abstract
OBJECTIVE There is a need for a robust tool to stratify the patient's risk with COVID-19. We assessed the prognostic values of cardiac biomarkers for COVID-19 patients. METHODS This is a single-centre retrospective cohort study. Consecutive laboratory-confirmed COVID-19 patients admitted to the Kobe City Medical Center General Hospital from July 2020 to September 2021 were included. We obtained cardiac biomarker values from electronic health records and institutional blood banks. We stratified patients with cardiac biomarkers as high-sensitive troponin I (hsTnI), N-terminal pro-B-type natriuretic peptide (NT-proBNP), creatine kinase (CK) and CK myocardial band (CK-MB), using the clinically relevant thresholds. Prespecified primary outcome measure was all-cause death. RESULTS A total of 917 patients were included. hsTnI, NT-proBNP, CK and CK-MB were associated with the significantly higher cumulative 30-day incidence of all-cause death (hsTnI: <5.0 ng/L group; 4.3%, 5.0 ng/L-99%ile upper reference limit (URL) group; 8.8% and ≥99% ile URL group; 25.2%, p<0.001. NT-proBNP: <125 pg/mL group; 5.3%, 125-900 pg/mL group; 10.5% and ≥900 pg/mL group; 31.9%, p<0.001. CK: CONCLUSIONS Elevation of cardiac biomarkers was associated with poor prognosis of COVID-19 patients.

Abstract
This study explores the effects of normobaric hypoxia and intermittent hypoxic training (IHT) on the physiological condition of the cardiac muscle in swimmers. Hypoxia has been reported to elicit both beneficial and adverse changes in the cardiovascular system, but its impact on the myocardium during acute exercise and altitude/hypoxic training remains less understood. We aimed to determine how a single bout of intense interval exercise and a four-week period of high-intensity endurance training under normobaric hypoxia affect cardiac marker activity in swimmers. Sixteen young male swimmers were divided into two groups: one undergoing training in hypoxia and the other in normoxia. Cardiac markers, including troponin I and T (cTnI and cTnT), heart-type fatty acid-binding protein (H-FABP), creatine kinase-MB isoenzyme (CK-MB), and myoglobin (Mb), were analyzed to assess the myocardium's response. We found no significant differences in the physiological response of the cardiac muscle to intense physical exertion between hypoxia and normoxia. Four weeks of IHT did not alter the resting levels of cTnT, cTnI, and H-FABP, but it resulted in a noteworthy decrease in the resting concentration of CK-MB, suggesting enhanced cardiac muscle adaptation to exercise. In contrast, a reduction in resting Mb levels was observed in the control group training in normoxia. These findings suggest that IHT at moderate altitudes does not adversely affect cardiac muscle condition and may support cardiac muscle adaptation, affirming the safety and efficacy of IHT as a training method for athletes.

Abstract
BACKGROUND Acute myocardial infarction is characterised by an imbalance in the supply and demand of oxygen in the heart. It requires urgent reperfusion, and poor outcomes are attributed to myocardial ischaemia-reperfusion injury. We aimed to evaluate the association between apelin-12 levels and creatine kinase-MB activity in predicting the effectiveness of reperfusion therapy in ST-segment elevation myocardial infarction (STEMI) patients. METHODS In this study we included 72 patients with the following criteria: chest pain suggestive of myocardial ischaemia for at least 30 minutes, an electrocardiogram with ST-segment elevation (measured at the J-point) ≥ 2 mm in leads V2-V3 and/or ≥ 1 mm in the other leads, rise of specific biomarkers such as cardiac troponin and the MB fraction of creatine kinase (CK-MB), and those who underwent reperfusion therapy. Blood samples for the measurement of apelin-12 and creatine kinase-MB were collected 12 hours after the reperfusion therapy. RESULTS In patients with thrombolysis in myocardial infarction (TIMI) flow grade ≤ 2, the median of the apelin-12 level was 1.80 ng/ml (0.46-9.20), and with TIMI flow 3, it was 5.76 ng/ml (1.14-15.2). Variability was observed in the apelin values (Mann-Whitney test) based on TIMI flow grade (p < 0.001), while no variability was observed for creatine kinase-MB (p < 0.18). The degree of association between apelin-12 and creatine kinase-MB levels was analysed with Pearson's correlation, enabling us to determine patients with successful reperfusion (determined as TIMI flow 3) (p < 0.004), and those with unsuccessful reperfusion (with TIMI flow ≤ 2) (p = 0.86). CONCLUSION In STEMI patients undergoing reperfusion therapy, Apelin-12 level was associated with creatine kinase-MB activity according to the success of the reperfusion.

Abstract
PURPOSE The study aims to assess the effects of dexmedetomidine (Dex) pretreatment on patients during cardiac valve replacement under cardiopulmonary bypass. METHODS For patients in the Dex group (n = 52), 0.5 μg/kg Dex was given before anesthesia induction, followed by 0.5 μg/kg/h pumping injection before aortic occlusion. For patients in the control group (n = 52), 0.125 ml/kg normal saline was given instead of Dex. RESULTS The patients in the Dex group had longer time to first dose of rescue propofol than the control group (P = 0.003). The Dex group required less total dosage of propofol than the control group (P = 0.0001). The levels of cardiac troponin I (cTnI), creatine kinase isoenzyme MB (CK-MB), malondialdehyde (MDA), and tumor necrosis factor-α (TNF-α) were lower in the Dex group than the control group at T4, 8 h after the operation (T5), and 24 h after the operation (T6) (P <0.01). The Dex group required less time for mechanical ventilation than the control group (P = 0.003). CONCLUSION The study suggests that 0.50 µg/kg Dex pretreatment could reduce propofol use and the duration of mechanical ventilation, and confer myocardial protection without increased adverse events during cardiac valve replacement.

Abstract
Background/aim Anemia in the first week after birth, which could affect growth, development, and organ function, should be an important warning sign to clinicians. The aim of this study was to assess the related risk factors of early neonatal anemia and to analyze the effect of anemia on the expression levels of myocardial markers in newborns. Materials and methods Clinical data from 122 confirmed cases of anemic newborns and 108 nonanemic newborns were collected to analyze the independent risk factors for early anemia using logistic regression analyses. Blood samples were collected from both groups for the detection of myocardial markers, including the protein marker cardiac troponin T (cTnT), as well as enzyme markers creatine kinase isoenzyme MB (CK-MB) and lactate dehydrogenase (LDH). Results Multivariate logistic regression analysis revealed that preterm birth (OR: 3.589 [1.119-11.506], p < 0.05), multiple pregnancy (OR: 4.117 [1.021-16.611], p < 0.05), and abnormal placenta (OR: 4.712 [1.077-20.625], p < 0.05) were independent risk factors for early neonatal anemia. The levels of myocardial markers, including cTnT (303.1 ± 244.7 vs. 44.2 ± 55.41 ng/L), CK-MB (6.803 ± 8.971 vs. 2.5326 ± 2.927 μkat/L), and LDH (32.42 ± 35.26 vs. 19.73 ± 17.13 μkat/L), were significantly higher in the anemic group than in the nonanemic group. Conclusion Multiple pregnancy, preterm birth, and abnormal placenta were identified as risk factors for early neonatal anemia. The occurrence of early neonatal anemia was associated with increased levels of myocardial markers.

Abstract
ABSTRACT This study aimed to explore the correlation between QTc dispersion (QTcd) and soluble growth-stimulating gene 2 protein (sST2) after heart rate correction in patients with acute carbon monoxide poisoning heart disease. Among the 150 patients, 35 cases had severe toxic heart disease. The concentrations of sST2, cardiac troponin I, and creatine kinase-MB in the severe group began to increase from admission, 24 hours, and 2 days, respectively, and their detected values were all higher than those in the nonsevere group and the normal control group. There were statistically significant differences in sST2 and QTcd between the poisoning, nonsevere, and normal control groups before the treatment. There was a statistically significant difference between the indexes of the poisoning groups at different degrees 2 and 3 days after poisoning. Receiver operating characteristic curve analysis confirmed the sensitivity and specificity of sST2 and QTcd. The correlation analysis showed that sST2 and QTcd levels were positively correlated with the incidence of severe heart disease at admission. Generally, the combined observation of sST2 and QTcd improved the prediction sensitivity and were early predictor indexes of toxic heart disease.

Abstract
ABSTRACT To investigate how high-intensity exercise influences an athlete's myocardial resilience and the correlation between myocardial resilience and markers of myocardial ischemic injury.Fifteen swimmers participated in high-intensity exercises. Cardiac ultrasound was performed before and after exercise on each subject. Left ventricular general strain, systolic general strain rate, and the differences (▴general strain and ▴ general strain rate, respectively), before and after exercise were analyzed. Blood was collected at the morning of the exercise day and 6 hours after exercise to measure cardiac enzyme indicators.The correlation between myocardial resilience and markers of myocardial injury were evaluated. Most cardiac enzymes concentrations increased after exercise (P < .05). Cardiac troponin I, creatine kinase MB, and cardiac troponin T were all correlated with the degree of ▴ peak strain (differential value of posterior wall basal segment before and after exercise) and ▴ peak strain rate (differential value before and after exercise) (P < .05).After high-intensity exercise, the concentrations of creatine kinase MB and cardiac troponin T in the blood are positively correlated with two-dimensional ultrasound deformation indices, proving the fact that the seindices can be used as a diagnostic basis for myocardial injury, and are more sensitive than general strain. The two-dimensional strain echocardiogram is non-invasive and easily accepted by the patient. It can make up for the shortage of myocardial enzymes in the injury areas, including weak timeliness and the inability to locate injury.

OBJECTIVE To investigate the value of high-sensitivity C-reactive protein (hs-CRP) in evaluating the myocardial damage and prognosis in children with mycoplasmal pneumonia. MATERIALS A total of 150 children with mycoplasmal pneumonia were selected. According to their serum creatine kinase isoenzyme (CK-MB) level, they were divided into 72 cases of the myocardial damage group and 78 cases of the non-myocardial damage group. Eighty healthy children undergoing physical examination were selected as the control group. The electrocardiography results and serum CK-MB and hs-CRP levels were compared among the subjects. The correlations among the above indexes were analyzed. RESULTS The levels of hs-CRP and CK-MB in the myocardial damage group were significantly higher than those in the nonmyocardial damage group and control group, respectively (P<0.05). The rates of abnormal hs-CRP and abnormal electrocardiogram in the myocardial damage group were significantly higher than those in the non-myocardial damage group, respectively (P<0.05). In the 150 children with mycoplasmal pneumonia, the serum hs-CRP and CK-MB levels were positively correlated (P<0.001), and the abnormal hs-CRP rate was positively correlated with the abnormal electrocardiogram rate (P<0.001). In the myocardial damage group, the serum levels of hs-CRP and CK-MB after treatment were significantly lower than those before treatment, respectively (P<0.05). After treatment, each index in the myocardial damage group had no significant difference with those in the control group (P>0.05). CONCLUSION hs-CRP may be an important index for evaluating the myocardial damage and prognosis in children with mycoplasmal pneumonia. The combination of hs-CRP and CK-MB detection has obvious guiding significance for the monitoring and treatment of mycoplasmal pneumonia complicated by myocardial damage.

Abstract
This study aimed to investigate the effect of the therapy of amiodarone combined with atorvastatin on cardiac function of patients with acute myocardial infarction after percutaneous coronary intervention (PCI). A total of 90 patients with acute myocardial infarction who underwent PCI in the tertiary care hospital from January 2019 to January 2020 were selected as the subjects and randomly assigned into the control group and the study group, with 45 cases in each group. All the subjects had undergone PCI. The control group received amiodarone while those the study group received atorvastatin additionally. Comparison was done on the clinical efficacy, cardiac function, myocardial injury indicator and inflammatory factor between the two groups. The overall response rate (ORR) in the study group was significantly higher than that in the control group (P<0.05); patients in the study group had markedly better cardiac function compared with those in the control group (P<0.001); patients in the study group had considerably lower creatine kinase (CK) index, creatine kinase-MB (CK-MB) index, tumor necrosis factor (TNF-α) and interleukin-6 (IL-6) as opposed to those in the control group (P<0.001). It was observed that the therapy of amiodarone combined with atorvastatin could effectively improve the clinical indicators and cardiac function of patients with acute myocardial infarction after PCI. It is effective and worthy of wide promotion and application.

Abstract
OBJECTIVES We conducted a systematic review and meta-analysis with meta-regression of creatine kinase-MB (CK-MB), a biomarker of myocardial injury, in COVID-19 patients. METHODS We searched PubMed, Web of Science and Scopus, for studies published between January 2020 and January 2021 that reported CK-MB, COVID-19 severity and mortality (PROSPERO registration number: CRD42021239657). RESULTS Fifty-five studies in 11,791 COVID-19 patients were included in the meta-analysis. The pooled results showed that CK-MB concentrations were significantly higher in patients with high disease severity or non-survivor status than patients with low severity or survivor status (standardized mean difference, SMD, 0.81, 95% CI 0.61 to 1.01, p<0.001). The rate of patients with CK-MB values above the normal range was also significantly higher in the former than the latter (60/350 vs 98/1,780; RR = 2.84, 95%CI 1.89 to 4.27, p<0.001; I2 = 19.9, p = 0.254). Extreme between-study heterogeneity was observed (I2 = 93.4%, p<0.001). Sensitivity analysis, performed by sequentially removing each study and re-assessing the pooled estimates, showed that the magnitude and direction of the effect size was not modified (effect size range, 0.77 to 0.84). Begg's (p = 0.50) and Egger's (p = 0.86) t-tests did not show publication bias. In meta-regression analysis, the SMD was significantly and positively associated with the white blood count, aspartate aminotransferase, myoglobin, troponin, brain natriuretic peptide, lactate dehydrogenase, and D-dimer. CONCLUSIONS Higher CK-MB concentrations were significantly associated with severe disease and mortality in COVID-19 patients. This biomarker of myocardial injury might be useful for risk stratification in this group.

Eur J Pharmacol 2021; 905:174183. [PMID: 34015318 DOI: 10.1016/j.ejphar.2021.174183] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/23/2020] [Revised: 05/08/2021] [Accepted: 05/12/2021] [Indexed: 10/21/2022]
Abstract
This study aimed to investigate whether methyl palmitate (MP) exerts cardioprotective effect against the ischemia/reperfusion (I/R) injury and its mechanisms underlying. The cultured adult cardiomyocytes were treated with vehicle or lactic acid ischemic buffer (pH 6.8) during hypoxia/reoxygenation. In addition, the cardioprotective effect of MP was evaluated using the ex vivo heart model of I/R injury. Here, we found that MP significantly reduced the I/R-induced cardiomyocyte death. Treatment with GW1100 (a GPR40-antagonist) or wortmannin (a phosphatidylinositol 3-kinase, PI3K, specific inhibitor) significantly attenuated the level of phospho-AKT (p-AKT) and abolished the MP-induced cardioprotection against the I/R-induced injury. Using the ex vivo I/R model, we also demonstrated that pretreatment with MP significantly reduced the size of myocardial infarction and the levels of cleaved-caspase 3 and MDA, and increased the protein levels of GPR40 and p-AKT induced by I/R. The cardioprotective effect of MP was evaluated also using the in vivo heart model of I/R injury. We demonstrated that post-ischemic treatment with MP significantly attenuated the size of myocardial infarction and the serum level of CK-MB induced by in vivo I/R model. Taken together, our data suggest that MP could provide significant cardioprotection against the I/R injury, and the underlying mechanisms by which MP prevented the cardiomyocyte death might be mediated through the GPR40-activated PI3K/AKT signaling pathways. These findings suggest the potential applications of MP in the treatment of I/R-induced heart injury.

Repeated use of SSRIs potentially associated with an increase on serum CK and CK-MB in patients with major depressive disorder: a retrospective study. Sci Rep 2021; 11:13365. [PMID: 34183728 PMCID: PMC8239012 DOI: 10.1038/s41598-021-92807-7] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/20/2021] [Accepted: 06/16/2021] [Indexed: 12/27/2022] Open
Abstract
There is a large amount of evidence that selective serotonin reuptake inhibitors (SSRIs) are related to cardiovascular toxicity, which has aroused concern regarding their safety. However, few studies have evaluated the effects of SSRIs on cardiac injury biomarkers, such as creatine kinase (CK) and creatine kinase isoenzyme (CK-MB). The purpose of our study was to determine whether SSRIs elevated CK and CK-MB levels of prior medicated depressive patients (PMDP) compared to first-episode drug-naïve depressive patients (FDDPs). We performed an observational and retrospective study involving 128 patients with major depressive disorder. Patients who had never used any type of antidepressant were designated FDDP; patients who had used only one type of SSRI but were not treated after a recent relapse were designated PMDP. Serum CK and CK-MB levels were measured before and after using SSRIs for a period of time. The duration of current treatment in the FDDP and PMDP groups was 16.200 ± 16.726 weeks and 15.618 ± 16.902 weeks, respectively. After SSRI treatment, levels of serum CK in the PMDP group were significantly higher than in the FDDP group. Univariate ANCOVA results revealed that PMDP was 22.313 times more likely to elevate CK (OR 22.313, 95% CI 9.605-35.022) and 2.615 times more likely to elevate CK-MB (OR 2.615, 95% CI 1.287-3.943) than FDDP. Multivariate ANCOVA revealed an interaction between the group and sex of CK and CK-MB. Further pairwise analysis of the interaction results showed that in female patients, the mean difference (MD) of CK and CK-MB in PMDP was significantly greater than that in FDDP (MD = 33.410, P = 0.000, 95% CI 15.935-50.886; MD = 4.613, P = 0.000, 95% CI 2.846-6.381). Our findings suggest that patients, especially females, who had previously used SSRI antidepressants were more likely to have elevated CK and CK-MB, indicators of myocardial muscle injury. Use of SSRIs should not be assumed to be completely safe and without any cardiovascular risks.

Abstract
Acute type A aortic dissection (ATAAD) constitutes a life-threatening aortic pathology with significant morbidity and mortality. Without surgical intervention the usual mortality rate averages between 1 and 2% per hour. Thus, an early diagnosis of ATAAD is of pivotal importance to direct the affected patients to the appropriate treatment. Preceding tests to find an appropriate biomarker showed among others an increased aggrecan (ACAN) mRNA expression in aortic tissue of ATAAD patients. As a consequence, we investigated whether ACAN is a potential biomarker for diagnosing ATAAD. Mean ACAN protein concentration showed a significantly higher plasma concentration in ATAAD patients (38.59 ng/mL, n = 33) compared to plasma of patients with thoracic aortic aneurysms (4.45 ng/mL, n = 13), patients with myocardial infarction (11.77 ng/mL, n = 18) and healthy volunteers (8.05 ng/mL, n = 12). Cardiac enzymes like creatine kinase MB and cardiac troponin T showed no correlation with ACAN levels in ATAAD patients. Receiver-operator characteristics (ROC) curve analysis for ATAAD patients versus control subjects an optimum discrimination limit of ACAN plasma levels at 14.3 ng/mL with a corresponding sensitivity of 97% and specificity of 81%. According to our findings ACAN is a reliable potential biomarker in plasma samples to detect ATAAD with high sensitivity and specificity.

Abstract
Briquette-based kotatsu, a traditional Japanese heating system, is still used in rural areas and has been linked to the development of acute carbon monoxide (CO) poisoning. This study aimed to investigate the occurrence of delayed neurologic sequelae (DNS) in patients with acute CO poisoning caused by briquette-based kotatsu.This retrospective study included 17 patients treated for acute CO poisoning due to briquette-based kotatsu, between April 2017 and March 2020. Patients were divided into either a sequelae group (3 patients) or a non-sequelae group (14 patients) based on the presence or absence, respectively, of DNS. Demographic data, kotatsu characteristics, clinical findings, and therapies were compared between the 2 groups.Significant differences were noted in patient posture during their initial discovery. Specifically, all non-sequelae patients only had their legs under the kotatsu quilt and all sequelae patients had their entire bodies under the kotatsu quilt (P = .001). There were no statistically significant differences in carbon monoxide levels in hemoglobin (CO-Hb) or the creatine-kinase myocardial band (CK-MB), between the 2 groups; however, troponin-I levels were significantly higher in the sequelae group (P = .026). Abnormal head imaging findings were noted in 2 sequelae-group patients, with a significant difference between the groups (P = .025).We speculate that acute CO poisoning, caused by briquette-based kotatsu, may lead to DNS more frequently in patients in who cover their entire body with the kotatsu quilt and are found in this position. Patients should be warned about the dangers of acute CO poisoning when using briquette-based kotatsu.

Abstract
BACKGROUND Malignant hyperthermia is a rare but life-threatening pharmacogenetic muscle disorder characterized by abnormal hypermetabolic reactions and commonly triggered in susceptible individuals by volatile anesthetics or succinylcholine, or both. Unfortunately, the specific medicine dantrolene is not readily available in many countries including China. The aim of this study was to find the characteristics of malignant hyperthermia under the situation that dantrolene is not readily available. METHODS The cases of malignant hyperthermia reported on the most commonly used databases in China from 1985 to 2020 were analyzed. The inclusion criteria were the MH episodes only related to anesthesia. The exclusion criteria were dubious MH episodes only caused by Ketamine administration or MH episodes irrelevant to anesthesia. Independent samples t-test and Pearson's chi-squared test were applied to assess the difference between the survived and death cases. RESULTS Ninety-two cases of malignant hyperthermia reported on the most commonly used databases in China from 1985 to 2020 were analyzed. Median (IQR [range]) age was 18.5 (11.8-37.0 [0-70.0]) years. Compared with the survived cases, the death cases had higher maximum end-tidal partial pressure of CO2 (P = 0.033), the maximum arterial partial pressure of CO2 (P = 0.006), temperature first measured when the patient was first discovered abnormal (P = 0.012), and maximum temperature (P < 0.001). Besides, the death cases had less minimum pH (P < 0.001) and higher potassium (P < 0.001) and were more likely to have coagulation disorders (p = 0.018). Concerning treatment, cases used furosemide (P = 0.024), mannitol (P = 0.029), blood purification treatment (P = 0.017) had the advantage on the outcome. Creatine phosphokinase, myoglobin, and MB isoenzyme of creatine phosphokinase differed greatly among cases during the first week. 43 (46.7%) cases had congenital diseases. 12 (13.0%) cases were reported with abnormal laboratory test results or abnormal signs that are possibly relevant before anesthesia. CONCLUSIONS In countries that dantrolene is not readily available, early warning, diagnosis, and prompt effective therapies are crucial for MH patients to survive.

Abstract
This study aims to investigate whether Escin (ES) can protect against Cyclophosphamide (CPM)-induced cardiac damage. The experimental rats were categorized as Control, CPM (200 mg/kg), ES (10 mg/kg), and CPM + ES Groups, each having 6 members. Their heart tissues were stained with Hematoxylin and Eosin and the structural changes were investigated under the light microscope. The biochemical markers of ischemia modified albumin (IMA), creatine kinase (CK-MB), antioxidant activity indicators Catalase (CAT), and superoxide dismutase (SOD) activities were measured using blood samples. Besides, the effects of CPM, ES, and CPM + ES upon CAT and SOD activities were shown via molecular docking studies. In the Single-Dose CPM group, CK-MB and IMA levels significantly increased while SOD and CAT levels significantly decreased. However, the heart tissues were damaged. CK-MB and IMA levels significantly decreased in CP+ ES Group. On the other hand, SOD, and CAT levels significantly increased and reduced the damage remarkably. Our findings showed that ES treatment successfully reduced the toxic effects upon the rats. The conclusion is that ES treatment can help protect the heart tissue against CPM-induced toxicity. Both in-vivo results and molecular modeling studies showed that the negative effects of CPM upon SOD activity were bigger than that of CAT.

Abstract
The cholinergic anti-inflammatory pathway (CAP) was investigated in a variety of inflammatory conditions and constitutes a valuable line in their treatment. In the current study, we investigated the anti-inflammatory effect of GTS-21 (GTS) as a partial selective α7 nicotinic acetylcholine receptor (α7-nAchR) agonist in diabetic cardiomyopathy model in rats. This mechanism was elaborated to study whether it could alleviate the electrocardiographic, histopathological, and molecular levels of Toll-like receptor 4 (TLR4)/nuclear factor κB (NF-κB) pathway proteins. Diabetes was induced by the injection of streptozotocin (STZ) (50 mg/kg). Diabetic rats were treated with GTS (1 or 2 mg/kg/day), methyllycaconitine (MLA), a selective α7-nAchR antagonist (2 mg/kg/day) plus GTS (2 mg/kg/day), or the vehicle. All treatments were given by the intraperitoneal route. Ventricular rate and different electrocardiograph (ECG) anomalies were detected. Plasma levels of cardiac troponin T (cTnT) and creatine kinase MB (CK-MB) were measured by ELISA. Additionally, we elucidated the levels of several proteins involved in the TLR4/NF-κB pathway. Cardiac levels of TLR4 and phosphorylated protein kinase B (p-Akt) were detected by ELISA. The cardiac expression of myeloid differentiation primary response 88 (Myd88), tumor necrosis factor receptor-associated factor 6 (TRAF6), NF-κB, interleukin 1β (IL-1β), and active caspase-1 were evaluated by immunohistochemical staining. Finally, the cardiac levels of interleukin 6 (IL-6) and tumor necrosis factor α (TNF-α) were determined by ELISA. Diabetic rats showed (i) ECG signs of cardiomyopathy such as significant ST segment elevations, prolonged QRS, QT intervals, and ventricular tachycardia; (ii) increased plasma levels of cTnT and CK-MB; (iii) increased expression of cardiac TLR4; (iv) elevated immunohistochemical expression of cardiac, Myd88, TRAF6, and NF-κB; (v) diminution in the cardiac expression of p-Akt; and (vi) adaptive increases in cardiac expression of TNF-α and IL-6. These effects were ameliorated in diabetic rats treated with both doses of GTS. Pretreatment with MLA did not completely reverse the ameliorative effect of GTS on cTnT, TRAF6, TNF-α, and IL-6, thereby reinforcing the presence of possible α7-nAchR-independent mechanisms. The activation of α7-nAchR with GTS offers a promising prophylactic strategy for diabetic cardiomyopathy by attenuating the TLR4/NF-κB pathway.

Abstract
Cardiovascular complications have been well documented as the downside to conventional cancer chemotherapy. As a notable side effect of cisplatin (CDDP), cardiotoxicity represents a major obstacle to the successful treatment of cancer. It has been reported that Salvianolic acid B (SalB) possesses cardioprotective quality. However, the effect of SalB on cardiac damage caused by conventional cancer chemotherapy remains unclear. In this study, we clarified the protective effect of SalB on cisplatin-induced heart injury. Furthermore, in H9c2 cells, SalB dramatically reduced cisplatin-induced apoptosis and oxidative stress by modulating the nuclear factor erythroid-2-related factor 2 (Nrf2) signaling pathway. In conclusion, SalB had great potential in mitigating cisplatin-induced cardiac injury. Furthermore, more attention should be placed on natural active compounds containing SalB with antioxidant effects for the treatment of cardiomyopathy.

Abstract
OBJECTIVES To evaluate the efficacy and safety of intracoronary administration of prourokinase via balloon catheter during primary percutaneous coronary interventions in patients with acute ST-segment elevation myocardial infarction. METHODS Acute ST-segment elevation myocardial infarction patients underwent primary percutaneous coronary interventions were randomly divided into two groups: intracoronary prourokinase group (n = 125) and control group (n = 135). During primary percutaneous coronary interventions, prourokinase or saline was injected to the distal end of the culprit lesion via balloon catheter after balloon catheter dilatation. Demographic and clinical characteristics, infarct size, myocardial reperfusion, and cardiac functions were evaluated and compared between two groups. Hemorrhagic complications and major averse cardiovascular events (MACE) occurred in the 6-months follow-up were recorded. RESULTS No significant differences were observed between two groups with respect to baseline demographic, clinical, and thrombolysis in myocardial infarction grade (P > 0.05). In the intracoronary prourokinase group, more patients had ST-segment resolution (>50%) compared with control group (P < 0.05). Patients in the intracoronary prourokinase group showed lower levels of serum CK, creatine kinase-MB fraction, and troponin I than those in control group (P < 0.05). No significant differences in bleeding complications were observed between the two groups (P > 0.05). At 6-months follow-up, there was no statistically different of MACE between the two groups (P > 0.05). CONCLUSIONS Intracoronary administration of prourokinase via balloon catheter during primary percutaneous coronary interventions effectively improved myocardial perfusion and no increased bleeding in ST-segment elevation myocardial infarction patients.
