Surgical Methods

Cancer is one of the leading causes of death and disability worldwide. Timely diagnosis and the introduction of new effective treatments, including intensive radiation and chemotherapy regimens, have significantly improved survival forecasts in recent years. At the same time, the use of these types of treatment increases the risk of complications, one of which includes chemotoxic cardiopathies. In this regard, timely detection and treatment of complications from the cardiovascular system in patients receiving chemotherapy courses in combination with surgical methods of treatment is important. This paper presents an assessment of the significance of the use of cardiomarkers in the early diagnosis of acute myocardial infarction that developed during chemotherapy in a patient with tongue cancer with a complicated cardiac history. Patient M., 45 years old, was admitted for surgical treatment for cancer of the tongue St. IVA, T4aN1M0, cl. gr. 2. Planned laboratory and instrumental studies were performed. Contraindications for surgical treatment were not identified. A preoperative course of chemotherapy was performed, against the background of which the patient's condition worsened with symptoms of acute cardiopathy. A second ECG was urgently performed, as a result of which an increase in the ST segment in III, aVF was established, as well as a study of the concentration of cardiomarkers: highly sensitive troponin I, N-terminal propeptide of natriuretic hormone, creatine phosphokinase MB, myoglobin, the dynamics of changes in the level of which indicated the development of acute coronary syndrome. The complex application of diagnostic procedures, including the determination of the level of cardiomarkers, made it possible to timely diagnose the development of acute type 1 myocardial infarction in a patient with tongue cancer on the background of chemotherapy. When analyzing the entire array of clinical and laboratory data, the leading initiating factor that played a decisive role in the development of myocardial infarction in this case was, in our opinion, a preoperative course of polychemotherapy with paclitaxel and carboplatin, which have cardiotoxicity. Thus, the category of patients with an initial unfavorable background, due to a common malignant process and the presence of a history of cardiodisfunction, requires more careful preparation for preoperative courses of polychemotherapy, including cardiotropic therapy with mandatory monitoring of the level of the main cardiomarkers. The most significant changes were in the levels of creatine phosphokinase MB, troponin I, and myoglobin, which were recorded in the first hours of myocardial infarction. An association was found between an increase in troponin I concentration and an increase in the ST segment of the electrocardiogram.

Electrocardiographic Findings

Acute myocardial infarction is the leading cause of death in the world and the electrocardiogram remains the diagnostic tool for determining an acute myocardial infarction with ST-segment elevation. In spite of this, only half of the patients present classic electrocardiogram findings compatible with the ST-elevation infarction criteria. There is a spectrum of electrocardiographic findings that may reflect a phenomenon of acute coronary occlusion, which should be promptly recognized by the clinician to offer early reperfusion therapy.

Abstract Background Loeffler’s endocarditis is an inflammatory cardiac condition of hypereosinophilic syndrome which rarely involves coronary artery. When coronary artery is involved, known as eosinophilic coronary periarteritis, the clinical presentation, electrocardiographic changes and troponin level are extremely nonspecific and may mimic acute coronary syndrome. It is very important to make differential diagnosis for ECPA in order to avoid the unnecessary further invasive coronary angiography. Case presentation We report a case with chest pain, ST-segment depression in electrocardiogram and increased troponin-I mimicking acute non-ST-segment elevation myocardial infarction. However, quick echocardiography showed endomyocardial thickening with normal regional wall motion, which corresponded to the characteristics of Loeffler’s endocarditis. Emergent blood analysis showed marked increase in eosinophils and computed tomography angiography found no significant stenosis of coronary artery. Manifestations of magnetic resonance imaging consisted with findings of echocardiography. Finally, the patient was diagnosed as Loeffler’s endocarditis and possible coronary spasm secondary to eosinophilic coronary periarteritis. Conclusion This case exhibits the crucial use of quick transthoracic echocardiography and the emergent hematological examination for differential diagnosis in such scenarios as often if electrocardiogram change mimicking myocardial infarction.

Abstract A 53-year-old man, smoker, with diabetes mellitus, presented to the Emergency Department because of intense chest and abdominal pain, accompanied by dyspnea and high fever (39.5 °C) in the previous 4 days. Physical examination revealed an apical holosystolic murmur, with no signs of peripheral or pulmonary edema. An ECG showed sinus rhythm (90 bpm), complete right bundle branch block and minimal ST elevation in the inferior leads. A transthoracic echocardiography showed a mild reduction in left ventricle ejection fraction (EF 44%) due to akinesia of the infero-lateral wall, and mild mitral regurgitation (MR) due to mitral valve prolapse. An abdominal ultrasound ruled out signs of acute cholecystitis. Blood cultures were collected, and an empirical antibiotic therapy was started. Urgent blood exam showed high Troponin I (72000 ng/L) and high C-reactive protein (290 mg/L). An acute coronary syndrome was suspected based on clinical, ECG and echocardiography exam, and the patient underwent coronary angiography (Figure 1, Panel A) that showed no significant coronary stenosis, except for two small filling defects in the very distal part of both the left anterior descendent and the circumflex coronary arteries suspected for coronary emboli. The patient was then admitted in the coronary care unit, but after just a few hours his clinical and hemodynamic condition deteriorated. A transesophageal echocardiography was performed to rule out mechanical complications related to the acute myocardial infarction and revealed severe MR (Panel D), elongated, hyperechogenic and dysfunctioning antero-lateral papillary muscle (ALPM) with an abnormal mobility suggestive for myocardial abscess, and a mobile mass attached on the aortic valve suggestive for vegetation (Panel B and C). Due to the worsening hemodynamic status, the patient underwent urgent cardiac surgery. Histological analysis confirmed the presence of an abscess of the ALPM due to Staphylococcus Aureus. The patient died after a week because of cerebral hemorrhage. Autopsy reported multiple lungs, renal and cerebral embolic septic infarctions. Learning points coronary artery embolization and papillary muscle abscess are very rare and often fatal consequences of infective endocarditis (IE). High (otherwise unexplained) fever and signs of embolism are minor Duke modified criteria for IE that should lead the physician to look for major criteria, such as positive blood cultures or echocardiography suggestive for IE. Emboli seen in the very distal part of the coronary arteries might have caused the ALPM abscess. Abstract P181 Figure

To test the feasibility of a small and simple system for telephonic transmission of 12-lead electrocardiograms (ECGs), 70 patients with acute coronary syndrome admitted to the cardiac care unit (CCU) were included in a feasibility study. The transmission system consisted of a belt with multiple electrodes, which was positioned around the chest. The ECG signal was sent to a call centre via a standard telephone line. In parallel, a standard 12-lead ECG was recorded on site. In a retrospective analysis, each lead of the transmitted ECG was compared with the on-site 12-lead ECG with regard to ST-segment changes and final diagnosis. In all 37 patients with acute ST-elevation myocardial infarction, the diagnosis was correctly established on the basis of telephone-transmitted ECGs. In 96% of limb and 88% of chest leads, ST elevations which were visible in standard ECGs were correctly displayed on telephonically transmitted ECGs. In the remaining 33 patients no false-positive diagnosis was made using transtelephonic ECG analysis. A control group of 31 patients without apparent heart disease showed high concordance between standard ECGs and telephonically transmitted ECGs. Telephonically transmitted 12-lead ECGs interpreted by a hospital-based internist/cardiologist might allow a rapid and accurate diagnosis of ST-elevation myocardial infarction and may increase diagnostic safety for the emergency staff during prehospital decision making and treatment of acute myocardial infarction.

Serum Paraoxonase

It is well known that serum paraoxonase (PON1) plays an important role in the protection of LDL from oxidation. PON1 55 polymorphism is currently investigated for its possible involvement in cardiovascular diseases. The objective of our study is to verify if PON1 55 polymorphism is associated with risk of acute coronary syndrome (ACS) and with biochemical myocardial ischemia markers, such as troponin I, creatine kinase (CK)-MB, myoglobin, and C-reactive protein. We analysed PON1 55 polymorphism in a total of 440 elderly patients who underwent an ACS episode: 98 patients affected by unstable angina (UA), 207 AMI (acute myocardial infarction) patients affected by STEMI (ST elevation), and 135 AMI patients affected by NSTEMI (no ST elevation). We found that individuals carrying PON1 55 LL genotype are significantly more represented among AMI patients affected by NSTEMI; moreover, the patients carrying LL genotype showed significantly higher levels of myoglobin in comparison to LM + MM carriers patients. Our study suggests that PON1 55 polymorphism could play a role in the pathogenesis of cardiac ischemic damage. In particular, the significant association between PON1 55 LL genotype and the occurrence of a NSTEMI may contribute to improve the stratification of the cardiovascular risk within a population.

Objective. To improve the results of acute myocardial infarction (AMI) treatment. Material and methods. We have analyzed 2 clinical cases of unfavorable course of AMI. Results. The middle aged patient who had ST segment elevation acute coronary syndrome received immediate full reperfusion therapy (thrombolysis and stenting). It was performed early in the course of the disease and demonstrated good angiographic result. Postoperatively there were no typical evolution of ECG signs of AMI. By the end of the first day we registered stent thrombosis with fatal outcome. Cause of death: acute left ventricular failure. The area of infarcted cardiac muscle was about 40 %, in the projection of the apex of the left ventricle the acute aneurysm was formed. Perhaps this situation has been associated with disorders of microcirculation in the infarcted area, which can be potentially neutralized by inhibitors 2b/3a receptors of platelets. This drug was given to this patient too late (during rethrombosis). In another observation (with the same circumstances) the inhibitor of IIb/IIIa GP receptors was given during the early postoperative period, what was followed by the natural course of AMI. Conclusion. These examples demonstrate the need of additional antiplatelet support (inhibitor IIb/IIIa GP receptors) in such clinical situations.

Aim.      To investigate the relationship between the osmotic fragility of erythrocytes and the course of acute myocardial infarction (MI).Methods.           An analysis of the osmotic fragility of erythrocytes was conducted using beta-blocker-based osmotic fragility test in sixty-two patients within the first 6 hours after onset of MI symptoms.Results. The results revealed that the patients with increased erythrocyte osmotic fragility experienced more complications after acute MI, such as left ventricular failure and cardiac arrhythmias (ventricular extrasystoles and ventricular tachycardia) (p = 0.026). Moreover, these patients exhibited greater myocardial injury - the concentration of biomarkers of myocardial necrosis, such as creatine phosphokinase, creatine phosphokinase MB and Troponin I was increased - p = 0.009, p = 0.032 and p = 0.001, respectively. In addition to that, the patients with high osmotic fragility had a larger number of hypokinetic and akinetic segments, high impaired myocardial contractility index, and low ejection fraction. The impaired myocardial contractility index was significantly higher in patients with increased erythrocyte osmotic fragility (1.5 (1.22; 1.75) vs 1.12 (1.0; 1.56), U = 157.5, p = 0.032).Conclusion. Increased erythrocyte osmotic fragility in patients was associated with greater myocardial injury, manifesting through the higher concentration of biomarkers of myocardial necrosis in blood, as well as higher number of hypokinetic segments.

Introduction: In spite of the enormous progress made over the last decades, acute coronary syndromes remain the leading cause of death globally. Inflammation plays an important role in coronary artery disease development. Although the role of inflammatory biomarkers in acute obstructive myocardial infarction is well established, there is no data regarding the potential differences between acute myocardial infarction (AMI) with ST segment elevation, AMI without ST segment elevation (NON-STEMI) and non-obstructive acute myocardial infarction (MINOCA), respectively. Also, it is well known that cardiac rehabilitation of acute myocardial infarction survivors significantly improves their long-term prognosis. Aim of the study: To asses the possible existing differences between patients with STEMI, NON-STEMI and MINOCA in terms of clinical and paraclinical parameters, especially inflammatory biomarkers. A second objective of our study was to describe the relationship between inflammatory, cardiac necrosis enzymes and left ventricle systolic function. Material and methods: The study included 35 adult patients admitted in the Cardiology service of the Niculae Stăncioiu Heart Institute, Cluj-Napoca with acute myocardial infarction. Demographic, clinical, echocardiographic and laboratory data were analyzed. Patients were divided into 3 groups, 19 patients (54.2%) were diagnosed with STEMI- group 1, 9 patients (25.7%) with NON-STEMI- group 2 and 7 patients (20%) with MINOCA- group 3, respectively. Dosage of serum inflammatory markers was performed on the day of admission. Results and conclusion: The most common associated cardiovascular risk factor was arterial hypertension (65.7% of patients). Markers of myocardial necrosis (CK, CK-MB, hs Troponin) were significantly higher in patients with STEMI (p <0.05) in comparison with NON-STEMI and MINOCA patients. Congestive heart failure was most frequently encountered in STEMI patients. hsCRP value was higher among patients with STEMI. The value of ESR was significantly higher among patients with NON-STEMI. Serial dosage of inflammation biomarkers in patients with recent acute myocardial infarction may serve as valuable risk stratification instruments and also for functional capacity and recovery status assessment in patients included in cardiac rehabilitation programs.
