BACKGROUND

Chest pain is a common reason for emergency room visits. The HEART score is used as a risk stratification tool to aid in clinical decision making. The HEART score is a useful tool due to its good sensitivity, however it has low specificity. The SVEAT score was developed as an improved risk stratification tool which outperformed the HEART score in previous studies. Both the performance of HEART and SVEAT scores lack data in our locality.

To compare the performance of Symptoms, Vascular disease, Electrocardiography, Age, Troponin-I (SVEAT) score and History, Electrocardiography, Age, Risk factors, Troponin-I (HEART) score as predictors of in-hospital Major Adverse Cardiovascular Events (MACE) among adult patients admitted in Chong Hua Hospital Cebu for chest pain.

This single-center, retrospective, observational analytic study included adult patients, ages 18 years old and above, who were admitted for chest pain from January 1, 2022 to December 31, 2022. All patients who passed the inclusion and exclusion criteria were included in the data analysis. Both SVEAT and HEART scores were calculated for each of the included subjects. The performance of both scoring criteria was compared using logistic regression and area under the receiving-operator characteristic curve.

A total of 113 cases were analyzed after exclusion criteria were applied. A total of 50 (44.2%) individuals suffered MACE. The difference in AUC of both SVEAT (0.946, 95%CI) and HEART (0.936, 95%CI) was not statistically significant (95% CI – 0.013 – 0.033, p = 0.400). With a cut-off ofCONCLUSION

SVEAT and HEART scores had similar performance in predicting in hospital MACE. Using a cut-off value of

OBJECTIVE: To retrieve and collate the earliest recorded texts in ancient acupuncture-moxibustion prescriptions for chest obstruction and heart pain, and explore the acupoint composition principles. METHODS: The Excel 2016 software was used to build a data set of ancient textual records on acupuncture-moxibustion prescriptions for chest obstruction and heart pain. After the terminology related to etiology, pathogenesis, accompanying symptoms, acupoints, and treatment methods unified, the frequency statistical analysis and association rule algorithms were applied to analyze the implicit association patterns among various elements of syndrome differentiation, treatment selection, and acupoint selection in ancient prescriptions from multiple dimensions. RESULTS: The basic acupoints of high frequency in ancient acupuncture-moxibustion treatment for chest obstruction and heart pain were Daling (PC7), Neiguan (PC6), Taixi (KI3), Taichong (LR3), Shangwan (CV13), Yongquan (KI1), and Xinshu (BL15). The prescription was mostly composed of yuan-source points. Besides, the combinations of two of five-shu points, five-shu points with luo-connecting points, and yuan-source points with luo-connecting points were common. The high-frequency points were from the pericardium meridian of hand-jueyin, conception vessel, kidney meridian of foot-shaoyin, liver meridian of foot-jueyin, and bladder meridian of foot-taiyang, generally distributed on the yin part of the arm, abdominal region, the yin part of foot, the back, and the yin part of the leg. Zhigou (TE6), Zusanli (ST36), Baihui (GV20), and Jiuwei (CV15), as well as the specific acupoint combinations, were used for chest obstruction and heart pain due to qi stagnation. Moxibustion was more suitable for chest obstruction and heart pain caused by qi reversion, cold and qi stagnation. Shaohai (HT3) was invariably selected when hand tremor was accompanied; Zhongchong (PC9) combined with Daling (PC7) was selected specially for feverish sensation in the palms. Moxibustion was exclusively applied to Shangwan (CV13), and Taixi (KI3) was often stimulated with moxibustion. At Neiguan (PC6) and Daling (PC7), moxibustion was delivered in combination with acupuncture (high confidence was presented in acupuncture). CONCLUSION In ancient acupuncture-moxibustion treatment for chest obstruction and heart pain, the points of the pericardium meridian of hand-jueyin are predominant, coordinated with those of the liver meridian of foot-jueyin, kidney meridian of foot-shaoyin, conception vessel, and bladder meridian of foot-taiyang. It follows the principles of acupoint selection, "the pericardium acting on behalf of the heart", "regulating qi as the priority", "combination of yuan-source points with luo-connecting points", and "selecting nearby points along the affected meridians".

INTRODUCTION: Elevated troponin, while essential for diagnosing myocardial infarction, can also be present in non-myocardial infarction conditions. The myocardial-ischaemic-injury-index (MI3) algorithm is a machine learning algorithm that considers age, sex and cardiac troponin I (TnI) results to risk-stratify patients for type 1 myocardial infarction. METHOD: Patients aged ≥25 years who presented to the emergency department (ED) of Singapore General Hospital with symptoms suggestive of acute coronary syndrome with no diagnostic 12-lead electrocardiogram (ECG) changes were included. Participants had serial ECGs and high-sensitivity troponin assays performed at 0, 2 and 7 hours. The primary outcome was the adjudicated diagnosis of type 1 myocardial infarction at 30 days. We compared the performance of MI3 in predicting the primary outcome with the European Society of Cardiology (ESC) 0/2-hour algorithm as well as the 99th percentile upper reference limit (URL) for TnI. RESULTS: There were 1351 patients included (66.7% male, mean age 56 years), 902 (66.8%) of whom had only 0-hour troponin results and 449 (33.2%) with serial (both 0 and 2-hour) troponin results available. MI3 ruled out type 1 myocardial infarction with a higher sensitivity (98.9, 95% confidence interval [CI] 93.4-99.9%) and similar negative predictive value (NPV) 99.8% (95% CI 98.6-100%) as compared to the ESC strategy. The 99th percentile cut-off strategy had the lowest sensitivity, specificity, positive predictive value and NPV. CONCLUSION The MI3 algorithm was accurate in risk stratifying ED patients for myocardial infarction. The 99th percentile URL cut-off was the least accurate in ruling in and out myocardial infarction compared to the other strategies.

INTRODUCTION

Sinus of Valsalva aneurysms (SOVA) are rare conditions in which a portion of the aortic root dilates due to weakness of the aortic wall, which can eventually lead to rupture, leading to a shunt from the aorta into any one of the cardiac chambers. Some patients can present asymptomatically and are diagnosed incidentally, while others can present with precipitous courses with symptoms of chest pain, palpitations and heart failure. When left untreated, these patients have poor prognosis.

A total of six patients are presented in this case series. These patients were seen in a national tertiary hospital from 2018 to 2024. The patients had varied characteristics, with ages ranging from 24-57 years old. Most of the patients were males. The presenting symptoms are also varied, with dyspnea being the most common symptom and a murmur being the most common sign. The most commonly involved sinus was the right coronary sinus draining into the right ventricle, with half of the patients presenting with concomitant ventricular septal defects. Five out of the six patients underwent successful open repair of their ruptured SOVAs and were eventually discharged.

Early identification of the cardiac lesion is important to clinch the diagnosis and plan for eventual definitive management. Imaging studies such as transthoracic echocardiogram are needed to visualize the defect, which is classically described as a windsock deformity. Transesophageal echocardiography may present clearer images to assess the anatomy better preoperatively. Medical management is usually done to bridge the patient to more definitive therapy, either through endovascular closure if the anatomy permits it or through surgical repair. Urgent and timely repair is needed to ensure improved survival in these patients.

OBJECTIVE: We aimed to assess the feasibility and superiority of machine learning (ML) methods to predict the risk of Major Adverse Cardiovascular Events (MACEs) in chest pain patients with NSTE-ACS. METHODS: Enrolled chest pain patients were from two centers, Beijing Anzhen Emergency Chest Pain Center Beijing Bo'ai Hospital, China Rehabilitation Research Center. Five classifiers were used to develop ML models. Accuracy, Precision, Recall, F-Measure and AUC were used to assess the model performance and prediction effect compared with HEART risk scoring system. Ultimately, ML model constructed by Naïve Bayes was employed to predict the occurrence of MACEs. RESULTS: According to learning metrics, ML models constructed by different classifiers were superior over HEART (History, ECG, Age, Risk factors, & Troponin) scoring system when predicting acute myocardial infarction (AMI) and all-cause death. However, according to ROC curves and AUC, ML model constructed by different classifiers performed better than HEART scoring system only in prediction for AMI. Among the five ML algorithms, Linear support vector machine (SVC), Naïve Bayes and Logistic regression classifiers stood out with all Accuracy, Precision, Recall and F-Measure from 0.8 to 1.0 for predicting any event, AMI, revascularization and all-cause death ( vs. HEART ≤ 0.78), with AUC from 0.88 to 0.98 for predicting any event, AMI and revascularization ( vs. HEART ≤ 0.85). ML model developed by Naïve Bayes predicted that suspected acute coronary syndrome (ACS), abnormal electrocardiogram (ECG), elevated hs-cTn I, sex and smoking were risk factors of MACEs. CONCLUSION Compared with HEART risk scoring system, the superiority of ML method was demonstrated when employing Linear SVC classifier, Naïve Bayes and Logistic. ML method could be a promising method to predict MACEs in chest pain patients with NSTE-ACS.

Chest pain is one of the most common complaints in the emergency department. Diseases of the heart, aorta, lungs, esophagus, stomach, mediastinum, pleura, and abdominal viscera can all cause chest discomfort (Gulati et al., 2021; Jiao et al., 2021; Lu et al., 2022). Clinicians in the emergency department are expected to immediately recognize life-threatening chest pain (Jiao et al., 2021). Delayed diagnosis further increases the risk of complications and mortality (Liu et al., 2021). In this case, we present an elderly Chinese female who had a history of myocardial infarction two years previously, with chest pain eventually found to be caused by ingestion of a duck bone.

Objective: To summarize the clinical characteristics of bronchial-pulmonary artery fistula and evaluate the effect of interventional closure of bronchial-pulmonary artery fistula. Methods: A retrospective case study was conducted. Fifteen children with hemoptysis who were diagnosed with bronchial-pulmonary artery fistula in Beijing Children's Hospital, Capital Medical University from January 2018 to March 2022 were selected. Their clinical symptoms and chest-enhanced CT findings were recorded. The children who failed to improve after anti-infection and hemostasis treatment were treated with transcatheter embolization through microparticles under digital subtraction angiography (DSA). The efficacy and post-operation recurrence were evaluated. Results: There were 15 children, including 9 males and 6 females, aged 9.8 (3.7, 12.1) years, weighing 35 (16, 55) kg. There was hemoptysis of varying degrees before surgery. Only 2 children had decreased hemoglobin. Chest enhanced CT showed that their bronchial arteries were thickened and tortuous, including 11 cases of single vessel disease and 4 cases of multivessel disease; 11 children had varying degrees of pneumonia and 4 children had atelectasis. Except for one case effectively treated with medical therapy, the remaining 14 cases were all treated with transcatheter interventional closure with embolic microparticles, among whom 12 had their fistula completely blocked with a single operation and the other 2 children underwent multiple operations because of too many fistulas. One child had extensive bronchial-pulmonary artery fistula which failed to be blocked completely even after multiple operations. Among the remaining 13 children, only 2 patients whose fistula was considered to be completely closed had recurrence presenting with hemoptysis at 3 months and 2 years after the operation, and no hemoptysis was found after the second closure. All children were discharged without chest pain, spinal cord paraplegia, or other serious complications. Fourteen children were followed up for 1.4 (0.9,2.9) years, among whom one still has intermittent mild hemoptysis due to incomplete closure and the rest had a satisfactory outcome. Conclusions: Hemoptysis is the first symptom of bronchial-pulmonary artery fistula. For children with failed medical treatment, transcatheter closure with an embolic pellet is effective, safe and feasible, with a low recurrence rate.

Objective: To analyze the clinical characteristics, diagnosis and treatment of anomalous aortic origin of a coronary artery (AAOCA) in children. Methods: There were 17 children diagnosed with AAOCA from January 2013 to January 2022 in Shanghai Children's Medical Center, Shanghai Jiao Tong University School of Medicine.Their clinical manifestations, laboratory and imaging data, treatment and prognosis were retrospectively analyzed. Results: These 17 children included 14 males and 3 females, with the age of (8.7±3.5) years. There were 4 anomalous left coronary artery (ALCA) and 13 anomalous right coronary artery (ARCA). Seven children presented with chest pain or chest pain after exercise, three patients presented with cardiac syncope, one complained chest tightness and weakness, and the other six patients had no specific symptoms. Cardiac syncope and chest tightness occurred in patients with ALCA. Fourteen children had the dangerous anatomical basis of myocardial ischemia caused by coronary artery compression or stenosis on imaging. Seven children had coronary artery repair, of whom two were ALCA and five were ARCA. One patient had received heart transplantation because of heart failure. The incidence of adverse cardiovascular events and poor prognosis in ALCA group was higher than that in ARCA group (4/4 vs. 0/13, P<0.05). They were followed up in the outpatient department regularly for 6 (6, 12) months; except for the one who lost visit, the rest of the patients had a good prognosis. Conclusions: Cardiogenic syncope or cardiac insufficiency usually occurs in ALCA, and adverse cardiovascular events and poor prognosis are more common in ALCA than in ARCA. Early surgical treatment should be considered for children with ALCA and ARCA accompanied by myocardial ischemia.

Physical traumas are tragic and multifaceted injuries that suddenly threaten life. Although it is the third most common cause of death in all age groups, one out of four trauma patients die due to thoracic injury or its complications. Blunt injuries constitute the majority of chest trauma. This indicates the importance of chest trauma among all traumas. Blunt chest trauma is usually caused by motor vehicle accident, falling from height, blunt instrument injury and physical assault. As a result of chest trauma, many injuries may occur, such as pulmonary injuries, and these require urgent intervention. Chest wall and pulmonary injuries range from rib fractures to flail chest, pneumothorax to hemothorax and pulmonary contusion to tracheobronchial injuries. Following these injuries, patients may present with a simple dyspnea or even respiratory arrest. For such patient, it is important to understand the treatment logic and to take a multidisciplinary approach to treat the pulmonary and chest wall injuries. This is because only 10% of thoracic trauma patients require surgical operation and the remaining 90% can be treated with simple methods such as appropriate airway, oxygen support, maneuvers, volume support and tube thoracostomy. Adequate pain control in chest trauma is sometimes the most basic and best treatment. With definite diagnosis, the morbidity and mortality can be significantly reduced by simple treatment methods.

Objective: The aim of this systematic review and meta-analysis is to determine summary estimates of the diagnostic accuracy of mean platelet volume for the diagnosis of myocardial infarction among adult patients with angina and/or its equivalents in terms of sensitivity, specificity, diagnostic odds ratio, and likelihood ratios. Methodology: The primary search was done through search in electronic databases. Cross-sectional, cohort, and case-control articles studying the diagnostic performance of mean platelet volume in the diagnosis of acute myocardial infarction in adult patients were included in the study. Eligible studies were appraised using well-defined criteria. Results: The overall mean MPV value of those with MI (9.702 fl; 95% CI 9.07 – 10.33) was higher than in those of the non-MI control group (8.85 fl; 95% CI 8.23 – 9.46). Interpretation of the calculated t-value of 2.0827 showed that there was a significant difference in the mean MPV values of those with MI and those of the non-MI controls. The summary sensitivity (Se) and specificity (Sp) for MPV were 0.66 (95% CI; 0.59 - 0.73) and 0.60 (95% CI; 0.43 – 0.75), respectively. The pooled diagnostic odds ratio (DOR) was 2.92 (95% CI; 1.90 – 4.50). The positive likelihood ratio of MPV in the diagnosis of myocardial infarction was 1.65 (95% CI; 1.20 – 22.27), and the negative likelihood ratio was 0.56 (95% CI; 0.50 – 0.64). Conclusion The intended role for MPV in the diagnostic pathway of myocardial infarction would perhaps be best as a triage tool. MPV values can discriminate between those who have MI and those without. For a patient with angina presenting with elevated MPV values, it is 1.65 times more likely that he has MI. It is implied that the decision to treat a patient with angina or its equivalents as a case of MI could be supported by an elevated MPV value.
