Predicting cancer therapy-induced cardiotoxicity: the role of troponins and other markers. 总被引:5,自引:0,他引:5
Several anticancer drugs have been associated with cardiac toxicity, especially the anthracyclines and trastuzumab. The pathogenesis of anthracycline-associated toxicity has been well described, whereas the mechanism of trastuzumab-associated toxicity is unknown. Although routine cardiac imaging studies (e.g. echocardiogram or multiple gated acquisition scans) may identify subclinical evidence of myocardial dysfunction, available data do not support their routine use for monitoring asymptomatic patients undergoing cancer therapy. Other modalities such as nuclear medicine scintigraphy with indium-111-antimyosin antibody and endomyocardial biopsy have been shown to be useful in identifying early cardiac damage, but their routine use is limited by practical considerations such as feasibility and cost. Consequently, there is significant interest in developing simple and reproducible methods for identifying patients at risk for treatment-induced myocardial damage. Available data suggest that circulating markers such as troponins and natriuretic peptides could potentially be useful for this purpose. Measurement of plasma troponin levels are commonly used in clinical practice in order to provide diagnostic and prognostic information in patients with myocardial ischaemia. Elevated levels may likewise correlate with anthracycline-induced cardiac damage, although plasma levels are only minimally elevated (well below that associated with ischaemia), and elevations may persist for weeks or months after anthracycline exposure. Clinical trials are currently evaluating the role of these markers in predicting both early and late, clinical and subclinical damage associated with anthracyclines and trastuzumab. 相似文献

目的通过分析急性心肌梗死患者血清中肌钙蛋白I抗体水平的变化,探讨其在急性心肌梗死中的临床意义。方法 2011年4月-2012年3月急性心肌梗死68例,分别于确诊及确诊后24 h内取静脉血检测肌钙蛋白I(cTnI)及肌钙蛋白I自身抗体,根据检测结果分为肌钙蛋白I自身抗体阳性组(13例)及阴性组(55例)。比较两组患者确诊时及24 h血清cTnI水平,同时采用Gensini积分和SYNTAX评分评价冠脉病变程度;分别记录、比较两组于确诊7 d及随访180 d的左室射血分数(LVEF)、左室舒张末期内径(LVEDD)、左室收缩末期内径(LVESD),评价肌钙蛋白I自身抗体与急性心肌梗死患者近期、远期的心功能变化的关系。结果两组患者确诊时cTnI水平无显著性差异,但24 h cTnI阳性组水平[(13.57±7.38)μg/L]明显高于阴性组[(7.37±9.24)μg/L](P〈0.01);两组中多支病变患者比例差异无统计学意义,但阳性组Gesini积分(85.54)、SYNTAX积分(15.73)明显高于阴性组(Gesini积分52.73,SYNTAX积分9.99)(P〈0.01),PCI术后7 d与180 d两组患者的左室重构指数、LVEF也存在显著差异(P〈0.05)。结论肌钙蛋白I自身抗体可能影响急性心肌梗死患者早期cT-nI的浓度,并导致cTnI峰值的延迟;而肌钙蛋白I自身抗体阳性往往提示患者血管病变较重,心肌梗死时累及范围较广,梗死面积较大。远期随访结果提示,肌钙蛋白I自身抗体的存在可能影响心肌梗死患者术后心功能的恢复。 相似文献

Trastuzumab is associated with cardiotoxicity, manifesting as a decrease of the left-ventricular ejection fraction (LVEF). Administration of anthracyclines prior to trastuzumab increases risk of cardiotoxicity. High-sensitive troponin T and N-terminal-pro-brain natriuretic peptide (NT-proBNP) are molecular markers that may allow earlier detection of drug-induced cardiotoxicity. In this analysis we aimed to quantify the kinetics and exposure–response relationships of LVEF, troponin T and NT-proBNP measurements, in patients receiving anthracycline and trastuzumab. Repeated measurements of LVEF, troponin T and NT-proBNP and dosing records of anthracyclines and trastuzumab were available from a previously published clinical trial. This trial included 206 evaluable patients with early breast cancer. Exposure to anthracycline and trastuzumab was simulated based on available dosing records and by using a kinetic-pharmacodynamic (K-PD) and a fixed pharmacokinetic (PK) model from literature, respectively. The change from baseline troponin T was described with a direct effect model, affected by simulated anthracycline concentrations, representing myocyte damage. The relationship between trastuzumab and LVEF was described by an indirect effect compartment model. The EC50 for LVEF decline was significantly affected by the maximum troponin T concentration after anthracycline treatment, explaining 15.1% of inter-individual variability. In this cohort, NT-proBNP changes could not be demonstrated to be related to anthracycline or trastuzumab treatment. Pharmacodynamic models for troponin T and LVEF were successfully developed, identifying maximum troponin T concentration after anthracycline treatment as a significant determinant for trastuzumab-induced LVEF decline. These models can help identify patients at risk of drug-induced cardiotoxicity and optimize cardiac monitoring strategies. 相似文献

Carbon monoxide (CO) poisoning is the leading cause of death from intoxication. In CO poisoning, it is important to know if there are any symptoms regarding myocardial damage, which are usually unobserved as a result of hypoxia. This study was planned to assess myocardial damage in young healthy patients with CO poisoning. Eighty-three young healthy cases who had been exposed to CO were included in this study. The demographic and clinical characteristics, the origin of CO gas and smoking habits of the patients were recorded. The evaluation of ECG, peripheral ABG, complete blood count and serial cardiac biomarkers (creatine kinase, creatine kinase-myocardial band and troponin I) measurements were performed in all cases. Additionally, echocardiogram (ECHO) and myocardial perfusion single-photon emission computed tomography (SPECT) were performed at the appropriate times in all cases. The mean age of the patients was 27.3 +/- 10.9 years. The main complaint of the patients was loss of consciousness with a 62.7% rate. The average carboxyhaemoglobin level of the patients was 34.4 +/- 15.9%. Sinus tachycardia was present in 26.5% of patients. Diagnostic ischaemic ECG changes were present in 14.4% of patients. In myocardial SPECT, myocardial ischaemic damage was observed in 9 cases, in 6 of whom ECHO findings were also confirmed. Myocardial damage due to CO poisoning should not be ignored. If patients are at risk in terms of myocardial damage, further studies, such as ECHO and scintigraphy are needed to determine myocardial damage resulting from CO poisoning. However, in the young adults of the risk group, if the baseline ECG and serial cardiac biomarkers are normal, further studies such as ECHO and scintigraphy, considering the length of exposure and the severity of poisoning, may not be necessary for the evaluation of myocardial damage due to CO poisoning. 相似文献

Invasive measurement of carboxyhemoglobin (COHb) by blood gas analysis (BGA) is accepted as the standard diagnostic procedure in diagnosis of inhalation injury and carbon monoxide (CO) intoxications. The main disadvantage of BGA with COHb testing is the unavailability in pre-hospital rescue conditions. The non-invasive SpCO analysis using pulse CO oximetry (Rad57, Masimo Corp., USA) represents an easy-to-handle device to facilitate the diagnosis of CO intoxication. Between January 2006 and August 2008, 20 patients who were admitted with CO intoxication to our burn centre were included in this study. Blood gas analysis including COHb testing was performed on the first day, hourly. At the same time, SpCO was determined using the Rad57 pulse CO oximeter. Patients received inhalative oxygen according to the parameters of blood gas analysis or hyperbaric oxygenation if COHb?>?10%. Five young healthy volunteers served as control group. The SpCO of the volunteers was cross-checked against their COHb levels, which were measured by blood gas analysis. Results of pulse CO oximetry revealed a mean error of approximately 3.15% from the results achieved by blood gas analysis. If COHb resulted in values higher than 10%, the bias remained approximately the same (3.43%/precision 2.362%). When different blood gas analyzers in our department were tested with the same patient sample, a mean error of 2.4% was found. This is only 1% lower compared to the mean error of pulse CO oximetry. Therefore, pulse CO oximetry represents a reliable measurement technique that is easy to handle and could facilitate the early diagnosis of CO intoxication in pre-hospital rescue conditions. 相似文献

Occasional or suicidal methanol intoxications are a permanent problem for most Poisoning Centers around the World. Therefore it is important to look for new diagnostic and clinical prognostic methods. In the present paper 5 cases of methanol intoxication were analyzed. At first the methanol concentrations in blood and urine were estimated with headspace gas chromatography technique. Next the urine samples were examined with 1H NMR spectroscopy, then the levels of ethanol, methanol and its metabolite, formate, lactate and trimethylamine-N-oxide with dimethylamine were evaluated. The concentrations of the above compounds were correlated with the patient's clinical status, the level of ethanol and methanol and biochemical parameters. The results indicate the correlation between clinical course of intoxication, prognostication and lactate level. There were no significant parallels for formate level as acidosis causing metabolite and initial methanol levels. In the urine samples of intoxicated patients the increased trimethyl-N-oxide and dimethylamine levels were observed, which may indicate renal cortex damage. Contrary to the opinion of some clinicians, methanol intoxication may be connected with renal functional disturbances. 1H NMR examination of urine appears to be an excellent tool to evaluate the clinical course of methanol intoxication. 相似文献
