Background: Chest pain is a frequent cause of health care contacts. We examined the prehospital management, in-hospital discharge diagnoses, and mortality of patients calling a non-emergency and emergency medical service with chest pain. Methods: The Copenhagen Emergency Medical Services (EMS) consists of a non-emergency medical helpline (calls to 1813) and emergency medical service (1-1-2 calls). We included all calls to the Copenhagen EMS with a primary complaint of chest pain from 2014 to 2018 in Copenhagen, Denmark. The outcomes were: emergency response (ambulance dispatch, other transports/self-transport/home visits, self-care, and unknown/cancelled response), in-hospital diagnosis within 7 days after the call (cardiovascular, pulmonary, or other non-cardiovascular/pulmonary) and 30-day mortality. Results: Among 4,834,071 calls, 91,671 were registered with chest pain at the Copenhagen EMS. The first call for each patient was kept for analysis (n = 66,762). In total, 91.4% were referred to the hospital, 75.8% (n = 50,627) received an ambulance and 15.6% (n = 10,383) received other transport/self-transport/home visits. Overall, 26.9% (n = 17,937) were diagnosed with a cardiovascular disease, 5.2% (n = 3,490) a pulmonary disease, 52.8% (n = 35.242) other non-cardiovascular/pulmonary disease, and 15.1% (n = 10,093) received no diagnosis. Among ambulance-transported patients, the prevalence of cardiovascular discharge diagnoses was higher (32.1%) and fewer received no diagnosis (11.0%). Cardiovascular disease was less prevalent among patients not transported by ambulance and patients not referred to hospital at all (2-13.4%) and in patients ≤ 40 years of age (< 10%). The 30-day mortality was below 5% regardless of diagnosis (0.6-4%), and 65,704 (98.4%) were still alive 30 days later. Conclusion: Nearly all patients calling with chest pain were referred for treatment. Among ambulance-transported patients, around half of the patients did not have a cardiovascular/pulmonary disease. While current practices appear reasonable, improved differentiation of chest pain patients in telephone consultations could potentially both improve the treatment and management of these patients and reduce the in-hospital burden of non-acute chest pain consultations.

Noncardiac chest pain is a challenging condition often encountered by primary care providers, emergency medicine physicians, and gastroenterologists. It is frequently accompanied by persistent symptoms, diagnostic uncertainty, decreased quality of life, and high health care burden. Gastroesophageal reflux disease is the most common esophageal cause followed by functional chest pain, and at least half of patients with noncardiac chest pain have psychiatric comorbidities such as anxiety or depression. Management is focused on identification of an underlying cause to target treatment and address psychiatric comorbidities. This article discusses the evaluation and management of the common gastrointestinal causes of noncardiac chest pain. [ABSTRACT FROM AUTHOR]

We assessed the association between troponin levels and all-cause mortality in individuals with chest pain who presented to the Charleston Area Medical Center Emergency Department (CAMC). We identified adult patients with chest pain as defined in the International Classification of Diseases 10 (R07) family group from the CAMC data warehouse between June 6, 2020, and June 6, 2021. These cases required a visit to the emergency room. We created 3 different cohorts to assess the endpoints of all-cause mortality at 30 days and 6 months. Patients were divided into the following 3 categories: negative troponin level, defined as high sensitivity troponin I (HSTNI) assay ≤15 pg/mL for women and ≤20 pg/mL for men; weakly positive, 21–88 pg/mL for men and 16–88 pg/mL for women; and strongly positive, >88 pg/mL for men and women. A propensity score matching analysis was also conducted using the negative group as a control; the weakly and strongly positive groups were compared to the control across differing cardiology covariates. This study introduces novel cutoffs for high-sensitivity troponin I (Beckman Coulter assay, Beckman Coulter, Inc., Chaska Campus, 1000 Lake Hazeltine Drive, Chaska, Minnesota 55318).

The article focuses on practical tips for pediatricians in diagnosing and managing precordial catch syndrome (PCS), a common yet underrecognized cause of chest pain in children and youth. It aims to increase awareness among primary care physicians to help them identify PCS, which is generally benign but can cause significant anxiety and unnecessary testing. It provides a detailed overview of PCS symptoms, suggests ways to differentiate it from other potential diagnoses.

Objective: International guidelines provide increasing support for computed tomography coronary angiography (CTCA) in investigating chest pain. A pathway utilising CTCA first‐line for outpatient stable chest pain evaluation was implemented in an Australian ED. Methods: In pre‐post design, the impact of the pathway was prospectively assessed over 6 months (August 2021 to January 2022) and compared with a 6‐month pre‐implementation group (February 2021 to July 2021). CTCA was recommended first‐line in suspected stable cardiac chest pain, followed by chest pain clinic review. Predefined criteria were provided recommending functional testing in select patients. The impact of CTCA versus functional testing was evaluated. Data were obtained from digital medical records. Results: Three hundred and fifteen patients were included, 143 pre‐implementation and 172 post‐implementation. Characteristics were similar except age (pre‐implementation: 58.9 ± 12.0 vs post‐implementation: 62.8 ± 12.3 years, P = 0.004). Pathway‐guided management resulted in higher first‐line CTCA (73.3% vs 46.2%, P < 0.001), lower functional testing (30.2% vs 56.6%, P < 0.001) and lower proportion undergoing two non‐invasive tests (4.7% vs 10.5%, P = 0.047), without increasing investigation costs or invasive coronary angiography (ICA) (pre‐implementation: 13.3% vs post‐implementation: 9.3%, P = 0.263). In patients undergoing CTCA, 40.7% had normal coronaries and 36.2% minimal/mild disease, with no difference in disease burden post‐implementation. More medication changes occurred following CTCA compared with functional testing (aspirin: P = 0.005, statin: P < 0.001). In patients undergoing ICA, revascularisation to ICA ratio was higher following CTCA compared with functional testing (91.7% vs 18.2%, P < 0.001). No 30‐day myocardial infarction or death occurred. Conclusions: The pathway increased CTCA utilisation and reduced downstream investigations. CTCA was associated with medication changes and improved ICA efficiency. [ABSTRACT FROM AUTHOR]

Introduction: Chest pain is the second most common chief complaint for patients undergoing evaluation in emergency departments (ED) in the United States. The American Heart Association recommends immediate physician interpretation of all electrocardiograms (ECG) performed for adults with chest pain within 10 minutes to evaluate for the finding of ST-elevation myocardial infarction (STEMI). The ECG machines provide computerized interpretation of each ECG, potentially obviating the need for immediate physician analysis; however, the reliability of computer-interpreted findings of "normal" or "otherwise normal" ECG to rule out STEMI requiring immediate intervention in the ED is unknown. Methods: We performed a prospective cohort analysis of 2,275 ECGs performed in triage in the adultED of a single academic medical center, comparing the computerized interpretations of "normal" and "otherwise normal" ECGs to those of attending cardiologists. ECGs were obtained with a GE MAC 5500 machine and interpreted using Marquette 12SL. Results: In our study population, a triage ECGwith a computerized interpretation of "normal" or "otherwise normal" ECG had a negative predictive value of 100% for STEMI (one-sided, lower 97.5% confidence interval 99.6%). None of the studied patients with these ECG interpretations had a final diagnosis of STEMI, acute coronary syndrome, or other diagnosis requiring emergent cardiac catheterization. Conclusion: In our study population, ECG machine interpretations of "normal" or "otherwise normal" ECG excluded findings of STEMI. The ECGs with these computerized interpretations could safely wait for physician interpretation until the time of patient evaluation without delaying an acute STEMI diagnosis. [ABSTRACT FROM AUTHOR]

Aims The objectives were to describe differences in self-reported health at discharge between women diagnosed with angina or unspecific chest pain and investigate the association between self-reported health and adverse outcomes within 3 years. Methods and results Data from a national cohort study were used, including data from the DenHeart survey combined with 3 years of register-based follow-up. The population included two groups of women with symptoms of angina but no diagnosis of obstructive coronary artery disease at discharge (women with angina and women with unspecific chest pain). Self-reported health measured with validated instruments was combined with register-based follow-up on adverse outcomes (a composite of unplanned cardiac readmissions, revascularization, or all-cause mortality). Associations between self-reported health and time to first adverse outcomes were investigated with Cox proportional hazard models, reported as hazards ratios with 95% confidence intervals. In total, 1770 women completed the questionnaire (49%). Women with angina (n = 931) reported significantly worse self-reported health on several outcomes compared to women with unspecific chest pain (n = 839). Within the 3 years follow-up, women with angina were more often readmitted (29 vs. 23%, P = 0.011) and more underwent revascularization (10 vs. 1%, P < 0.001), whereas mortality rates were similar (4 vs. 4%, P = 0.750). Self-reported health (physical and mental) was associated with adverse outcomes between both groups (on most instruments). Conclusion Women with angina reported significantly worse self-reported health on most instruments compared to women with unspecific chest pain. Adverse outcomes varied between groups, with women diagnosed with angina experiencing more events. Registration ClinicalTrials.gov (NCT01926145). [ABSTRACT FROM AUTHOR]

The prevalence of Thoracic Pain (TP) is estimated to be low compared to other common musculoskeletal disorders such as nonspecific low back pain (LBP). Notably, compared to LBP, TP or referral pain to the thoracic area potentially may involve serious pathologies. Visceral referral of pain may present to the thoracic spine or anteriorly in the abdomen or chest. Rupture of the spleen in the absence of trauma or previously diagnosed disease is rare and rarely documented in emergency medicine literature. The incidence of red flags are higher in the thoracic area in comparison to the lumbar or cervical regions, but TP can also be of musculoskeletal origin and for this reason it is important to assess the origin of pain. This case report describes the clinical history, evaluation and management of a 60-year-old complaining of upper thoracic, bilateral shoulder, and right upper quadrant abdominal pain. The patient's clinical findings from a physiotherapist's assessment led to a referral to a physician to explore a potential non-musculoskeletal origin. A splenectomy was required due to a non-traumatic rupture of the spleen. After 20 days of hospitalization from the surgery, the patient returned to all normal activities of daily living. The purpose of this current case report is to describe the clinical reasoning of a physiotherapist screening a patient who presented with thoracic pain due to a spontaneous rupture of the spleen, that resulted in a referral to another health practitioner.

Objectives: We compared the number of accesses, causes, and instrumental evaluations of chest pain in children between the pre-COVID-19 era and the COVID-19 period and analyzed the assessment performed in children with chest pain, highlighting unnecessary examinations. Methods: We enrolled children with chest pain admitted to our emergency department between January 2019 and May 2021. We collected demographic and clinical characteristics and findings on physical examinations, laboratory tests, and diagnostic evaluations. Then, we compared the number of accesses, causes, and instrumental assessments of chest pain between the pre-COVID-19 era and the COVID-19 era. Results: A total of 111 patients enrolled (mean age: 119.8 ± 40.48 months; 62 males). The most frequent cause of chest pain was idiopathic (58.55%); we showed a cardiac origin in 4.5% of the cases. Troponin determination was performed in 107 patients, and the value was high only in one case; chest X-rays in 55 cases and echocardiograms in 25 cases showed pathological findings, respectively, in 10 and 5 cases. Chest pain accesses increased during the COVID-19 era (p < 0.0001), with no differences in the causes of chest pain between the two periods. Conclusions: The increase in accesses for chest pain during the COVID-19 pandemic confirms that this symptom generates anxiety among parents. Furthermore, our findings demonstrate that the evaluation of chest pain is still extensive, and new chest pain assessment protocols in the pediatric age group are needed. [ABSTRACT FROM AUTHOR]

The article describes the case of a 15-year-old boy who presented to a local emergency department with chest pain 2 days after receiving his second dose of the Pfizer-BioNTech COVID-19 vaccine. Topics covered include the medical history of the patient, the findings of the physical and medical examinations which led to the diagnosis of myocarditis, and patient outcome following treatment that included colchicine and indomethacin.

Background and Objective: Chest pain is one of the most common complaints in emergency departments (EDs). Self‐reported computerized history taking (CHT) programmes can be used for interpretation of the clinical significance of medical information coming directly from patients. The adoption of CHT in clinical practice depends on reactions and attitudes to the technology from patients and their belief that the technology will have benefits for their medical care. The study objective was to explore the user experience of the self‐reported CHT programme Clinical Expert Operating System (CLEOS) in the setting of patients visiting an ED for acute chest pain. Methods: This qualitative interview study is part of the ongoing CLEOS‐Chest Pain Danderyd Study. A subset (n = 84) of the larger sample who had taken part in self‐reported history taking during waiting times at the ED were contacted by telephone and n = 54 (64%) accepted participation. An interview guide with open‐ended questions was used and the text was analysed using directed content analysis. Results: The patients' experiences of the CLEOS programme were overall positive although some perceived it as extensive. The programme was well accepted and despite the busy environment, patients were highly motivated and deemed it helpful to make a diagnosis. Six categories of user experience emerged: The clinical context, The individual context, Time aspect, Acceptability of the programme, Usability of the programme and Perceptions of usefulness in a clinical setting. Conclusions: The programme was well accepted by most patients in the stressful environment at ED although some found it difficult to answer all the questions. Adjustments to the extent of an interview to better suit the context of the clinical use should be a future development of the programme. The findings suggest that CHT programmes can be integrated as a standard process for collecting self‐reported medical history data in the ED setting. Patient or Public Contribution: In the conduct of this study, patients contributed with interviews reflecting their usage of a self‐reported medical history‐taking programme. [ABSTRACT FROM AUTHOR]

To estimate the prognostic value of stress echo (SE) with the assessment of coronary flow velocity reserve (CFVR) and heart rate reserve (HRR) in patients admitted for chest pain with non-diagnostic EKG, negative troponin, and without inducible regional wall motion abnormalities (RWMA). 658 patients (age 67 ± 12 years) admitted to our Emergency Department with chest pain, non-diagnostic EKG, and negative serial troponin underwent dipyridamole (0.84 mg/kg in 6') SE with simultaneous assessment of RWMA, CFVR in the left anterior descending artery, and HRR as peak/rest heart rate. The outcome measure was all-cause mortality. Of the 658 patients initially enrolled, 20 (3%) showed RWMA during SE and were referred to ischemia-driven revascularization. In the remaining 638, CFVR was abnormal (≤ 2.0) in 148 patients (23%). HRR was abnormal (≤ 1.22 in patients in sinus rhythm, or ≤ 1.17 in patients with permanent atrial fibrillation) in 196 patients (31%). During a follow-up of 7.3 ± 4.3 years, 151 (24%) patients died. Survival at 8 years was 93% in patients with normal CFVR and HRR, 76% in patients with abnormal CFVR only, 73% in patients with abnormal HRR only, and 38% in those with abnormal CFVR and HRR (p < 0.0001). At multivariable analysis, abnormal CFVR (HR 1.49, 95% CI 1.05-2.10, p = 0.02) and abnormal HRR (HR 2.01, 95% CI 1.43-2.84, p < 0.0001) were independent predictors of survival. In admitted patients with non-ischemic EKG, negative serial troponin, and without RWMA during dipyridamole SE, a reduced CFVR and blunted HRR independently identify a subset with worse survival in the long term. Upper panel: Color and pulsed-wave Doppler with the electrocardiographic lead tracing of Four different response patterns (from left to right): normal CFVR and HRR; normal CFVR, abnormal HRR; abnormal CFVR, normal HRR; abnormal CFVR and HRR. Lower panel: The annualized death rate for each of the four groups with negative SE for RWMA and stratified according to the presence of CFVR and HRR: none, one, or two abnormalities.

Introduction: Heart attacks (HAs) present clinically with varying symptoms, which are not always described by patients as chest pain (CP) or chest discomfort (CD). Emergency Medical Dispatchers (EMDs) select the CP/CD dispatch protocol for non-chest pain HA symptoms or classic HA complaint of CP/CD. Nevertheless, it is still unknown how often callers report HA symptoms other than CP/CD.Objectives: The objective of this study was to characterize the caller's descriptions of the primary HA symptoms, descriptions of the other HA symptoms, and the use of a case entry (CE) question clarifier.Methods: A retrospective descriptive study analyzed randomly selected EMD audios (where CD/CD protocol was used) from five accredited emergency communication centers in the United States. Several Quality Performance Review (QPR) experts reviewed the audios and recorded callers' initial problem descriptions, the use of and responses to the CE question clarifier, including the EMD-assigned final determinant code.Results: A total of 1,261 audios were reviewed. The clarifier was used only 8.5% of the time. The CP/CD symptoms were mentioned alone or with other problems 87.0% of the time. Overall, CP symptom was mentioned alone 70.8%, HA alone 4.0%, and CD symptom alone 1.4% of the time.Conclusion: 9-1-1 callers report potential HA cases using a variety of terms and descriptions-most commonly CP. Other less-common symptoms associated with a HA may be mentioned. Therefore, EMDs must be well-trained to be prepared to probe the caller with a clarifying query to elicit more specific information when "having a heart attack" is the only complaint initially mentioned.

Case Presentation: A 67-year-old woman developed sudden-onset severe dyspnea 24 h after a bilateral sequential lung transplant for COPD. She had an uneventful surgery performed on cardiopulmonary bypass support. She required two units of packed RBCs as well as fresh frozen plasma during the surgery. She was successfully extubated within 12 h of surgery. Her primary graft dysfunction score was grade 2, 1, and 1 at 0, 12, and 24 h, respectively. Approximately 24 h after the procedure, she complained of increasing shortness of breath without fever, chills, cough, or pleuritic chest pain. [ABSTRACT FROM AUTHOR]

Objectives: In stress echocardiography (SE), dipyridamole (DIP) and dynamic stress (ExSE) are reported as being safer than dobutamine stress echocardiography (DSE). We investigated whether these commonly used stressors cause myocardial injury, measured by high sensitivity troponin T (hsTnT). Methods: One hundred and thirty five patients (DSE n = 46, ExsE n = 46, DIP n = 43) with negative result of SE were studied. The exclusion criteria were known ischaemic heart disease (IHD), baseline wall motion abnormalities, left ventricle systolic dysfunction/regional wall motion abnormalities, septum/posterior wall ≥13 mm, diabetes/pre‐diabetes, baseline hsTnT level ≥14 ng/L, baseline blood pressure ≥160/100 mmHg, peak pulmonary pressure ≥45mmHg, eGFR <1ml/s/1.73m2, more than mild to moderate valvular disease and dobutamine side effects. HsTnT was measured before and 180 minutes after the test. Results: All patients had low pre‐test probabilities of having obstructive IHD. HsTnT increased in DSE, less so in ExSE, and was unchanged in the DIP group (∆hsTnT 9.4 [1.5–58.6], 1.1 [‐0.9–15.7], ‐0.1 [‐1.4–2.1] ng/L, respectively, p<0.001). In DSE, the ∆hsTnT was associated with peak dobutamine dose (r = 0.30, p = 0.045), test length (r = 0.43, p = 0.003) and atropine use (p<0.001). In ExSE, the hsTnT increase was more likely in females (p = 0.012) and the elderly (>65 years) (r = 0.32, p = 0.03); no association was found between atropine use (p = 0.786) or test length and ∆hsTnT (r = 0.10, p = 0.530). Conclusions: DSE is associated with myocardial injury in patients with negative SE, no injury was observed in DIP and only mild case in ExSE. Whether myocardial injury is causative of the higher reported adverse event rates in DSE remains to be determined. [ABSTRACT FROM AUTHOR]

Objectives: To investigate the impact of a CT-first strategy on all-cause and cardiovascular mortality in patients presenting with chest pain in outpatient cardiology clinics.Methods: Patients with a first presentation of suspected angina pectoris were identified and their data linked to the registrations of Statistics Netherlands for information on mortality. The linked database consisted of 33 068 patients. CT-first patients were defined as patients with a CT calcium score and coronary CT angiography, within 6 weeks after their initial visit. Propensity score matching (1:5) was used to match patients with and without a CT-first strategy. After matching, 12 545 patients were included of which 2308 CT-first patients and 10 237 patients that underwent usual care.Results: Mean age was 57 years, 56.3% were women and median follow-up was 4.9 years. All-cause mortality was significantly lower in CT-first patients (n=43, 1.9%) compared with patients without CT (n=363, 3.5%) (HR: 0.51, 95% CI 0.37 to 0.70). Furthermore, CT-first patients were more likely to receive cardiovascular preventative and antianginal medication (aspirin: 44.9% vs 27.1%, statins: 48.7% vs 30.3%, beta-blockers: 37.8% vs 25.5%, in CT-first and without CT-first patients, respectively) and to undergo downstream diagnostics and interventions (coronary interventions: 8.5% vs 5.7%, coronary angiography: 16.2% vs 10.6% in CT-first and without CT-first patients, respectively).Conclusions: In a real-world regular care database, a CT-first strategy in patients suspected of angina pectoris was associated with a lowering of all-cause mortality.

Case Presentation: A 43-year-old woman with a medical history of hypothyroidism, psoriasis, and tobacco abuse (30-pack year history) who had quit smoking several months prior to presentation presented with pleuritic chest pain. She also noted a 2-year history of progressive numbness and weakness in her bilateral upper and lower extremities that now prevented her from completing her activities of daily living. She had worsening exertional dyspnea and a subjective 50-lb weight loss over the past year. [ABSTRACT FROM AUTHOR]

Background: The HEART Pathway is a validated protocol for risk stratifying emergency department (ED) patients with possible acute coronary syndrome (ACS). Its performance in different age groups is unknown. The objective of this study is to evaluate its safety and effectiveness among older adults. Methods: A pre‐planned subgroup analysis of the HEART Pathway implementation study was conducted. This prospective interrupted time series accrued adult ED patients with possible ACS who were without ST‐elevation across three US sites from 11/2013–01/2016. After implementation, providers prospectively used the HEART Pathway to stratify patients as low‐risk or non‐low‐risk. Patients were classified as older adults (≥65 years), middle‐aged (46–64 years), and young (21–45 years). Primary safety and effectiveness outcomes were 30‐day death or MI and hospitalization at 30 days, determined from health records, insurance claims, and death index data. Fisher's exact test compared low‐risk proportions between groups. Sensitivity for 30‐day death or MI and adjusted odds ratios (aORs) for hospitalization and objective cardiac testing were calculated. Results: The HEART Pathway implementation study accrued 8474 patients, of which 26.9% (2281/8474) were older adults, 45.5% (3862/8474) middle‐aged, and 27.5% (2331/8474) were young. The HEART Pathway identified 7.4% (97/1303) of older adults, 32.0% (683/2131) of middle‐aged, and 51.4% (681/1326) of young patients as low‐risk (p < 0.001). The HEART Pathway was 98.8% (95% CI 97.1–100) sensitive for 30‐day death or MI among older adults. Following implementation, the rate of 30‐day hospitalization was similar among older adults (aOR 1.25, 95% CI 1.00–1.55) and cardiac testing increased (aOR 1.25, 95% CI 1.04–1.51). Conclusion: The HEART Pathway identified fewer older adults as low‐risk and did not decrease hospitalizations in this age group. [ABSTRACT FROM AUTHOR]

Case Presentation: A 50-year-old woman with a history of permanent atrial fibrillation (AF) treated with radiofrequency catheter ablation (RFCA) 6 months ago was admitted to the respiratory department of a tertiary hospital because of recurrent episodes of pleuritic chest pain in the preceding 5 months. The patient reported multiple visits to a regional hospital, where she was treated with broad-spectrum antibiotics after discovery of a left alveolar consolidation on chest radiograph (Fig 1), subsequently imaged with CT scan (Fig 2). On treatment failure and appearance of a left-sided pleural effusion during outpatient follow-up, the patient was re-admitted. Pleural fluid was obtained via thoracocentesis characterized by exudative features and lymphocytic predominance. Abdomen CT scan, with IV and per os contrast agent, was devoid of findings consistent with malignancy, and serum autoantibody levels were below positivity cut off values (antinuclear, cyclic citrullinated peptide antibody, rheumatoid factor, and anti-neutrophil cytoplasmic antibodies). The patient underwent flexible bronchoscopy without endobronchial pathology on visual inspection. Microbiologic studies and cytological examination of samples obtained by bronchial washing/aspiration yielded no clinically relevant information. Lung perfusion/ventilation scintigraphy was ordered to exclude chronic thromboembolic pulmonary hypertension; however, a deficit in vascularization for the left inferior lobe was found, prompting further investigation (Fig 3). Progression of left inferior lobe consolidation and the presence of a small pericardial effusion became evident on reimaging after a 2-month interval. The patient was empirically started on corticosteroids. After emergence of left hilar lymphadenopathy (< 1 cm), a PET-CT scan was performed. The left lower inferior lobe consolidation, whose metabolic activity pattern was consistent with that of inflammation (standardized uptake value equal to 4.4) (Fig 4), as well as the left sided-pleural effusion were markedly improved compared with previous imaging 20 days after corticosteroid initiation (Fig 2). On the grounds of recalcitrant pleuritic pain and pleural effusion recurrence during corticosteroid tapering, the patient was referred to the respiratory department of our university hospital to have her condition diagnosed.

Objectives: The HEART Pathway is a diagnostic protocol designed to identify low-risk patients with chest pain who can be safely discharged from the emergency department (ED) without hospitalization. Studies have reported a negative bias in identifying myocardial ischemia in females versus males and a different clinical pattern of cardiac ischemia across genders. This study sought to determine if the HEART Pathway recommendations are affected by negative bias in females. Materials and Methods: A retrospective cohort study was conducted in the ED of an academic tertiary medical center. Admission/discharge decisions made by physicians in male and female patients presenting with chest pain in 4/2014–7/2019 were compared with HEART Pathway protocol predictions. Probabilities were estimated with logistic regression analysis, and odds ratios and 95% confidence intervals were calculated. Results: The cohort included 772 patients, 485 male (63%) and 287 female (37%), of median age 54 years. On the basis of their presenting symptoms, 278 patients (36%) were admitted by the ED physician and 494 (64%) were discharged. Using the HEART Pathway protocol, 227 patients (29.4%) would be expected to be admitted and 545 (70.6%) discharged. The real-life admission rate was higher than possible with the HEART Protocol (p = 0.001). In a regression model, male sex was a significant factor favoring admission among the patients for whom the HEART Pathway predicted admission (p = 0.007). Conclusions: As the HEART Pathway is a validated risk-stratification tool, there is a high likelihood that serious coronary artery disease may be overlooked in women, even those who seek timely medical assistance.

Objective: To evaluate informal physician judgement versus pretest probability scores in estimating risk in patients with suspected coronary artery disease (CAD).Methods: We included 4533 patients from the PROMISE (Prospective Multicenter Imaging Study for Evaluation of Chest Pain) trial. Physicians categorised a priori the pretest probability of obstructive CAD (≥70% or ≥50% left main); Diamond-Forrester (D-F) and European Society of Cardiology (ESC) pretest probability estimates were calculated. Agreement was calculated using the κ statistic; logistic regression evaluated estimates of pretest CAD probability and actual CAD (as determined by CT coronary angiography), and clinical outcomes were modelled using Cox proportional hazard models.Results: Physician estimates agreed poorly with D-F (κ 0.16; 95% CI 0.14 to 0.18) and ESC (κ 0.04; 95% CI 0.02 to 0.05). Actual obstructive CAD was significantly more prevalent in both the high-likelihood (OR 3.30; 95% CI 2.30 to 4.74) and the intermediate-likelihood (OR 1.43; 95% CI 1.16 to 1.76) physician-estimated groups versus the low-likelihood group; ESC similarly differentiated between the three groups (OR 9.07; 95% CI 2.87 to 28.70; and OR 3.87; 95% CI 1.22 to 12.28). However, using D-F, only the high-probability group differed (OR 2.49; 95% CI 1.74 to 3.54). Only physician estimates were associated with a higher incidence of adjusted death/myocardial infarction/unstable angina hospitalisation in the high-probability versus low-probability group (HR 2.68; 95% CI 1.52 to 4.74); neither pretest probability score provided prognostic information.Conclusions: Compared with D-F and ESC estimates, physician judgement more accurately identified obstructive CAD and worse patient outcomes. Integrating physician judgement may improve risk prediction for patients with stable chest pain.Trial Registration Number: NCT01174550. [ABSTRACT FROM AUTHOR]

Case Presentation: A 49-year-old woman sought treatment at the hospital for evaluation of an enlarging cavitary mass of the right lung associated with worsening ipsilateral pleuritic chest pain and cough. She had recent hospitalizations for complications relating to recurrent lung abscesses, including one in which she underwent wedge resection of the right lung. She had been treated with several courses of antibiotics, which only temporarily relieved her symptoms. She did not report any fevers, chills, skin changes, diarrhea, or changes to her bowel habits. Her long-term medications included albuterol, dapsone, and prednisone 15 mg or 20 mg doses alternating daily. Her only past medical history was asthma and primary cutaneous pyoderma gangrenosum. The patient never smoked and did not report any recent sick contacts. [ABSTRACT FROM AUTHOR]

Background and Aims: Heart-type fatty acid-binding protein (H-FABP) is a novel marker of myocardial injury, released rapidly (<1 h) after the onset of myocardial injury and plays an important role in both early diagnoses of high-risk patients presenting with chest pain as well as an early reperfusion marker in post-thrombolytic patients. We aim to assess and compare the efficacy of H-FABP as an early marker of cardiac injury with Troponin I (cTnI) and creatinine Phospholinase Kinase (CPK-MB) and to correlate it with Left ventricular Ejection Fraction (LVEF)and percentage of stenosis in Coronary arteries. Material and Methods: Total of 300 patients (STEMI 150 and NSTEMI 150) with acute chest pain attending the emergency department within 6 hours after the onset of chest pain were included. Peripheral venous blood samples were obtained on admission, post thrombolysis at 60 minutes, and after 6 and 12 hours to measure a panel of conventional biomarkers FABP, cTnI and CPK. Echocardiography assessed Simpson’s LVEF and Trans mitral Doppler flow and the spectrum of coronary artery disease was defined by Coronary Angiography. Conclusion: FABP could reliably diagnose AMI patients 1 to 3 hours after admission over CPK MB and Troponin I and could also assess post-thrombolysis reperfusion in STEMI patients noninvasively over coronary angiography.

Objectives: The analytical sensitivity of high-sensitivity cardiac troponin T (hsTnT) assays has enabled rapid myocardial infarction rule-out algorithms for emergency department (ED) presentations. Few studies have analyzed the real-world impact of hsTnT algorithms on outcomes and operations.Methods: Comparison of ED length of stay (LOS) and 30-day outcomes (return to ED, inpatient admission, and mortality) for patients presenting with chest pain during 2 separate 208-day periods using a 0/1-hour hsTnT-enabled algorithm or fourth-generation TnT.Results: Discharge, 30-day readmission, and 30-day mortality rates were not significantly different with fourth-generation TnT vs hsTnT. Thirty-day return rates were significantly decreased with hsTnT (17.4% vs 14.9%; P < .01). For encounters with TnT measured at least twice and resulting in discharge, median ED LOS decreased by 61 minutes with the use of hsTnT (488 vs 427 minutes; P < .0001). Median time between first and second TnT results decreased by 82 minutes with hsTnT (202 vs 120 minutes; P < .0001), suggesting that the 0/1-hour algorithm was incompletely adopted.Conclusions: Implementation of the hsTnT algorithm was associated with decreased 30-day return rates and decreased ED LOS for a subset of patients, despite incomplete adoption of the 0/1-hour algorithm.

Introduction Thoracic solitary fibrous tumors (SFTs) are usually pleural-based lesions and diagnosed incidentally. The authors, hereby, report two cases of symptomatic SFT of the pleura with locally aggressive potential. Case 1 A 63-year-old male patient presented with chief complaints of dyspnea at rest and thoracic pain. Computed tomography scan revealed a mass of the right visceral pleura with multiloculated pleural effusion. Microscopic examination with immunostaining of the resected mass confirmed the diagnosis of malignant SFT. Local recurrence occurred after 5 months. Case 2 A 32-year-old patient had a massive tumor of the left hemithorax, invading the descending aorta and thoracic vertebrae, causing a shifting of the heart and mediastinum. A needle transcutaneous biopsy confirmed the diagnosis of SFT. Considering the respiratory failure, surgical treatment was preceded by a general preparation. The patient died few days before the operation owing to respiratory distress. Conclusion This paper sustains the heterogeneity of these tumors. SFT of the pleura could have malignant potential at first presentation or in a young patient. [ABSTRACT FROM AUTHOR]

Case Presentation: A 20-year-old woman presented with dry cough, right-sided thoracic pain, and gradually progressive dyspnea on exertion. She had no hemoptysis or fever. There was no relevant medical history. She was a never smoker and used no medication besides oral contraceptives. There were no other risk factors for a pulmonary embolism. There was a family history of ovarian and breast cancer. Physical examination showed a mildly ill-looking woman, with shallow breathing and normal blood oxygen saturation. Auscultation revealed normal breath sounds without crackles or wheezing. Laboratory testing showed a significantly increased D-dimer (4,560 μg/L [normal, < 500 μg/L]), elevated C-reactive protein (131 mg/L [normal, < 5 mg/L]), normal leucocytes, and elevated lactate dehydrogenase (825 units/L [normal, 50 to 250 units/L).

Background: A significant number of chest pain patients had previous cardiac imaging tests (CIT) performed before being presented to the Emergency Department (ED). The HEART (history, electrocardiogram, age, risk factors, and troponin) score has been used to risk-stratify chest pain patients in the ED, but not particularly for patients with CIT performed. We aim to modify the current HEART score with the addition of most recent CIT findings (referred to as HEART2 score), to predict a 30-day major adverse cardiac event (MACE) among ED chest pain patients, compare the performance accuracy of using HEART versus HEART2 score for 30-day MACE outcome predictions, and further determine the value of HEART2 in a subset group of ED chest pain patients (i.e., ones with previous CIT).Methods: This is a single-center observational study. We included chest pain patients with HEART scores calculated during their index ED visits. A modified HEART2 score was developed with the addition of CIT findings as one of the HEART2 components. Patients were divided into three groups, including low (≤ 3), moderate (4-6), and high-risk HEART/HEART2 scores (≥ 7). MACE occurrence of a patient with different risks of HEART and HEART2 scores and overall performance accuracy of HEART versus HEART2 score predicting MACE outcomes were compared.Results: We included a total of 9419 chest pain patients at ED, among which one out of five patients (1874/9419) had previous CIT performed. Fewer (38.2%) of such patients had low-risk HEART scores in comparison to 55.5% of low-risk HEART2 scores (p < 0.001). The MACE outcomes were similar in low-risk HEART patients compared with low-risk HEART2 patients (2.2% versus 3.1%, p = 0.3021). The overall performance accuracy of using the HEART2 score to stratify chest pain patients with previous CIT was better than using the HEART score's (AUC 0.74 versus 0.71, p = 0.0082).Conclusions: Using the HEART2 score might be suitable to stratify low-to-moderate risk chest pain patients at ED with a similar 30-days MACE occurrence compared to the HEART score. More importantly, with the use of similar low-risk criteria (HEART2 ≤ 3), over 45% more chest pain patients with previous CIT performed could be discharged directly from ED. [ABSTRACT FROM AUTHOR]

Background: The incidence of adverse perioperative cardiac complications after parathyroidectomy has not been well described. This study aimed to evaluate the incidence of perioperative chest pain and cardiac complications after parathyroidectomy and to evaluate risk factors that may identify patients who are more likely to benefit from a cardiac workup.Methods: We performed a retrospective study of all patients undergoing parathyroidectomy for primary hyperparathyroidism by a single endocrine surgeon at a tertiary endocrine centre between 2011 and 2018. Patient demographics, clinicopathologic variables, operative and postoperative details (reported chest pain, performance of a cardiac workup and new postoperative cardiac diagnosis) were reviewed. Patients with chest pain were compared to those without chest pain using the Fisher exact test and Student t test.Results: Fourteen of 295 patients (4.7%) reported chest pain in the immediate postoperative period. Most patients were investigated with a 12-lead electrocardiogram and troponin (n = 12/14), yet none were diagnosed with a cardiac event. When comparing patients with and without chest pain, there was no significant difference in age, gender, body mass index, presence of cardiovascular risk factors, American Society of Anesthesiologists score or length of surgery.Conclusion: Postoperative chest pain after parathyroidectomy is not an uncommon event and leads to a cardiac workup in most cases; however, the risk of significant postoperative cardiac events is minimal. In the "choosing wisely" era, one should evaluate each patient's pretest probability of such events and avoid extensive workup in low-risk patients to avoid unnecessary costs to the health care system.

Objective: We tested the hypothesis that patients with a potential acute coronary syndrome (ACS) and very low levels of high-sensitivity cardiac troponin I can be efficiently and safely discharged from the emergency department after a single troponin measurement.Methods: This prospective cohort study recruited 2255 consecutive patients aged ≥18 years presenting to the Emergency Department, Royal Perth Hospital, Western Australia, with chest pain without high-risk features but requiring the exclusion of ACS. Patients were managed using a guideline-recommended pathway or our novel Single Troponin Accelerated Triage (STAT) pathway. The primary outcome was the percentage of patients discharged in <3 hours. Secondary outcomes included the duration of observation and death or acute myocardial infarction in the next 30 days.Results: The study enrolled 1131 patients to the standard cohort and 1124 to the STAT cohort. Thirty-eight per cent of the standard cohort were discharged directly from emergency department compared with 63% of the STAT cohort (p<0.001). The median duration of observation was 4.3 (IQR 3.3-7.1) hours in the standard cohort and 3.6 (2.6-5.4) hours in the STAT cohort (p<0.001), with 21% and 38% discharged in <3 hours, respectively (p<0.001). No patients discharged directly from the emergency department died or suffered an acute myocardial infarction within 30 days in either cohort.Conclusions: Among low-risk patients with a potential ACS, a pathway which incorporates early discharge based on a single very low level of high-sensitivity cardiac troponin increases the proportion of patients discharged directly from the emergency department, reduces length of stay and is safe.Trial Registration Number: ACTRN12618000797279.

Chest pain is one of the most common presenting symptoms in the emergency department (ED). Among patients with abnormal troponins, it is imperative to quickly and accurately distinguish type 1 acute myocardial infarction (AMI) from other etiologies of myocardial injury. Although high-sensitivity troponin assays introduced a high negative predictive value for AMI, they have exposed the need for diagnostic modalities that can determine the etiology of acute myocardial injury. Cardiac magnetic resonance imaging (CMR) is an effective tool to risk stratifying chest pain among patients in the ED. CMR is non-invasive and has a lower cost of care and shorter length of stay compared to those of invasive coronary angiography. It also provides detailed information on cardiac morphology, function, tissue edema, and location and pattern of tissue damage that can help to differentiate many etiologies of cardiac injury. CMR is particularly useful to distinguish chest pain due to type 1 AMI versus supply-demand mismatch due to acute cardiac noncoronary artery disease. A detailed review of the literature has shown that CMR with stress testing is safe to use in patients presenting to the ED with chest pain, with or without abnormal troponins. CMR is a useful, safe, economical, and effective alternative to the traditional diagnostic tools that are typically used in this patient population. It is a practical tool to risk-stratify patients with possible cardiac pathology and to clarify diagnosis without invasive testing. [ABSTRACT FROM AUTHOR]

Background: Symptoms concerning for acute coronary syndromes (ACS) such as chest pain and dyspnea are some of the most common reasons for presenting to an emergency department (ED). The HEART score (history, electrocardiogram, age, risk factors and troponin) was developed and has been externally validated in an emergency setting to determine which patients with chest pain are at increased risk for poor outcomes. Our hospital adopted a HEART score-based protocol in late 2015 to facilitate the management and disposition of these patients. In this study we aimed to analyze the effects of the adoption of this protocol. Prior studies have included only patients with chest pain. We included both patients with chest pain and patients with only atypical symptoms. Methods: This was a retrospective chart review of two cohorts. We identified ED charts from sixmonth periods prior to and after adoption of our HEART score-based protocol. Patients in whom an electrocardiogram and troponin were ordered were eligible for inclusion. We analyzed data for patients with typical symptoms (chest pain) and atypical symptoms both together and separately. Results: We identified 1546 charts in the pre-adoption cohort and 1623 in the post-adoption cohort that met criteria. We analyzed the first 900 charts in each group. Discharges from the ED increased (odds ratio [OR[1.56, P<.001), and admissions for cardiac workup decreased (OR 0.46, P <.001). ED length of stay was 17 minutes shorter (P = .01). Stress testing decreased (OR 0.47, P<.001). We estimate a cost savings for our hospital system of over $4.5 million annually. There was no significant difference in inpatient length of stay or catheterization rate. When analyzing typical and atypical patients separately, these results held true. Conclusion: After adoption of a HEART score-based protocol, discharges from the ED increased with a corresponding decrease in admissions for cardiac evaluations as well as cost. These effects were similar in patients presenting without chest pain but with presentations concerning for ACS. [ABSTRACT FROM AUTHOR]

Background: Primary aldosteronism (PA) is the most frequent form of potentially reversible hypertension and coronary-pulmonary fistulas are increasingly recognized during routine coronary angiography or multidetector computed tomography for analysis of chest pain in hypertensive patients. Aldosterone hypersecretion has been associated with endothelial proliferation and pathological remodeling of the heart and arteries, though coronary artery fistulas have never been reported in patients with PA. Case presentation: The authors report the first case of PA with dilated cardiomyopathy unusually associated with electrocardiographic changes after normalization of hypokalemia and with the finding of a coronary-pulmonary fistula during coronary angiography. The clinical presentation and our diagnosis and treatment decision-making in the COVID-19 era are discussed below. Conclusions: Our case suggests a potential link between hypertensive patients with coronary artery fistulas and PA. [ABSTRACT FROM AUTHOR]

Case Presentation: A 55-year-old Chinese man without significant medical history presented with progressive chest discomfort and night sweats for the past 2 months. He experienced nonexertional chest tightness and palpitation at night, not associated with dyspnea. These symptoms usually lasted for a few minutes and resolved spontaneously. He also reported night sweats but denied fever, chills, or weight change. He had never smoked and denied recent contact with anyone known to be ill. [ABSTRACT FROM AUTHOR]

Case Presentation: A previously healthy, 9-year-old boy presented with five recurrent episodes of left-sided chest pain with low-grade fever over the last 18 months. The pain usually lasted for few hours, was severe and consistent, and resolved spontaneously. It worsened during inspiration, physical activity, and swallowing. He did not experience any cough, dyspnea, chills, cold sweats, or weight loss. His medical and family history was unremarkable. [ABSTRACT FROM AUTHOR]

Experiences of pain, especially chest pain, can be not only uncomfortable but also frightening. Among children and adolescents, symptoms of chest pain are relatively common, affecting about one in 10 youth. Chest pain symptoms can vary widely in presentation, in terms of their quality, frequency, severity, and history. When presenting during childhood and adolescence, chest pain rarely signifies a cardiac or health problem. Identifiable causes of chest pain typically are related to underlying pulmonary or gastrointestinal conditions. Less than 5% of pediatric chest pain cases are estimated to be related to actual heart disease. The vast majority of cases of chest pain, estimated at 80% to 85%, are benign and are described as "idiopathic," with an unknown cause. These cases are generally labeled as noncardiac chest pain (NCCP). [ABSTRACT FROM AUTHOR]

Background: A considerable proportion of patients with angina-like symptoms in an emergency department have very low pretest probability for acute myocardial infarction (AMI). Numerous algorithms exist for the exclusion of AMI, usually including laboratory tests. We aimed to investigate whether patients with very low risk can safely be identified by ECG and clinical information without biomarker testing, contributing to saving time and costs.Methods: Prospective diagnostic test accuracy study. We included all consecutive patients presenting with angina at the department of emergency medicine of a tertiary care hospital during a 1-year period. Using clinical information without biomarker testing and ECG, the "Mini-GRACE score," based on the well-established GRACE-score without using laboratory parameters was calculated. In a cohort design we compared the index test Mini-GRACE to AMI as reference standard in the final diagnosis using standard measures of diagnostic test accuracy.Results: We included 2755 patients (44% female, age 44 ± 17 years). AMI was diagnosed in 103 (4%) patients, among those 44% with STEMI. Overall 2562 patients (93%) had a negative "Mini-GRACE," four (0.2%) of these patients had myocardial infarction, and this results in a sensitivity of 96.1% (95% CI 90.4%-98.9%), specificity 96.5% (95.7%-97.1%), positive predictive value 51.3% (46.3%-56.3%) and negative predictive value 99.8% (99.6%-99.9%). Model performance according to C statistic (0.90) and Brier score (0.0045) was excellent. In rule-out patients 30-day mortality was 0.3% and 1-year mortality was 0.8%.Conclusions: Patients with very low risk of AMI can be identified with high certainty using clinical information without biomarker testing and ECG. Cardiac biomarkers might be avoided in such cases, potentially leading to a significant cost reduction. [ABSTRACT FROM AUTHOR]

Aim. To improve the identification and computed tomography (CT) diagnostic accuracy of chronic active Epstein-Barr virus (EBV)-associated enteritis (CAEAE) by evaluating its CT findings and clinical manifestation. Methods. The data of three patients with pathologically and clinically confirmed CAEAE who underwent CT enterography (CTE) were retrospectively reviewed from January 2018 to October 2019. The following data were evaluated: imaging characteristics (length of involvement, pattern of mural thickening, pattern of attenuation, perienteric abnormalities), clinical symptoms, endoscopic records, laboratory examinations, and pathologic findings. Results. Based on CT findings, two patients demonstrated segmental bowel wall thickening (involvement length >6 cm), asymmetric thickening, layered attenuation, fat stranding, and adenopathy, whereas the remaining one had no positive finding. The endoscopic results of all patients showed numerous irregular ulcers in the colon, and one patient had a focal esophageal ulcer. The major clinical symptoms were abdominal pain (n = 3), retrosternal pain (n = 1), fever (n = 3), diarrhea (n = 2), hematochezia (n = 1), and adenopathy (n = 3). The main laboratory examination indicators were increased serum EBV DNA load (n = 1) and increased inflammatory markers (n = 3). With regard to the main pathologic findings, all patients showed positive EBV-encoded RNA (EBER) situ hybridization in the colonic biopsy specimen, with one patient being positive in the esophagus. Conclusion. CAEAE is rare and is usually misdiagnosed as inflammatory bowel disease (IBD). The imaging features of CAEAE overlap with those of Crohn's disease and ulcerative colitis. The presence of segmental and asymmetric bowel wall thickening, layered attenuation, and fat stranding in the CTE image may be helpful in differentiating CAEAE from IBD. [ABSTRACT FROM AUTHOR]

INTRODUCTION: Accelerated diagnostic chest pain pathways are used widely in urban New Zealand hospitals. These pathways use laboratory-based troponin assays with good analytical precision. Widespread implementation has not occurred in many of New Zealand's rural hospitals and general practices as they are reliant on point-of-care troponin assays, which are less sensitive and precise. An accelerated chest pain pathway using point-of-care troponin has been adapted for use in rural settings. A pilot study in a low-risk rural population showed no major adverse cardiac events at 30 days. A larger study is required to be confident that the pathway is safe. AIMS: To assess the safety and effectiveness of an accelerated chest pain pathway adapted for rural settings and general practice using point-of-care troponin to identify low-risk patients and allow early discharge. METHODS: This is a prospective observational study of an accelerated chest pain pathway using point-of-care troponin in rural hospitals and general practices in New Zealand. A total of 1000 patients, of whom we estimate 400 will be low risk, will be enrolled in the study. OUTCOME MEASURES: The primary outcome is the proportion of patients identified by the pathway as low risk for a 30-day major adverse cardiac event. Secondary outcomes include the proportion of low-risk patients who were discharged directly from general practice or rural hospitals, the proportion of patients reclassified as having acute myocardial infarction by the pathway and the proportion of patients with low and intermediate risk safely managed in the rural hospital.

Background: Brugada syndrome (BrS) is sometimes diagnosed because of chest pain. Prevalence and characteristics of such BrS patients are unknown. Methods: A total of 200 BrS probands were retrospectively included. BrS diagnosis made because of chest pain (n = 34, 17%) was compared to the other ones. Results: BrS probands with diagnosis because of chest pain had significantly more often smoker habits, increased body mass index, and familial history of coronary artery disease but less frequently previous resuscitated sudden death/syncope or atrial fibrillation. Presence of coronary spasm and familial coronary artery disease were independently associated with BrS diagnosed because of chest pain. They presented more often with spontaneous type 1 ST elevation (59% vs 26%, P =.0004) and higher ST elevation during the episode of chest pain compared to other patients or compared to baseline electrocardiogram after chest pain resumption. ST elevation during chest pain was lower compared to ajmaline test. A total of 20% of them had significant coronary artery disease and four (11%) had coronary spasm, and they experienced more often recurrent chest pain episodes (24% vs 5%, P =.0002). Presence of chest pain at BrS diagnosis was not correlated to future arrhythmic events in univariate analysis. Only previous sudden cardiac death (SD)/syncope and familial SD were still significantly associated with outcome in multivariate analysis. Conclusion: Chest pain is a common cause for BrS diagnosis, although major part is not apparently explained by ischemic heart disease. Mechanisms leading to chest main remain unknown in the other ones. ST elevation is higher in this situation but does not seem to carry poor prognosis. [ABSTRACT FROM AUTHOR]

Objective: The Victorian Emergency Minimum Dataset (VEMD) collects administrative and clinical data for all presentations to Victorian public ED. The present study aimed to examine the level of agreement between the VEMD data and the medical record for a sample of patients coded as having acute cardiovascular conditions (acute coronary syndrome, stroke and transient ischaemic attack [TIA]) and unspecified chest pain in the VEMD. Methods: Six months of data provided to the VEMD from a large metropolitan hospital was obtained, and a random sample of 10% of cases (n = 310) were selected for review. Data for eight VEMD items were compared for concordance to data recorded in the ED medical record. Results: Complete concordance between the VEMD and medical records for all eight items was observed only for 101 (33%) presentations. Overall, the least concordant variables were those with a high number of coding options: usual type of accommodation (76%), referral pattern (84%) and primary diagnosis (85%). The concordance of the VEMD primary diagnosis varied when examined as individual codes (range 75%–100%) and when combined (acute coronary syndrome = 94%, stroke or TIA = 85% and chest pain unspecified = 75%). The level of agreement for some items improved when VEMD codings were combined. Conclusion: When compared to the medical record, our data suggest there is likely variation in the accuracy of some VEMD items, and suggests a larger prospective validation of the VEMD is warranted. For researchers using existing VEMD data, combining of some codes may be necessary. [ABSTRACT FROM AUTHOR]

Chest pain is a relatively common cause of admission to the Emergency Department, being related in most of the cases to benign conditions with only a minority of the cases affected by heart disease. Limited data are available about the follow up of these patients in terms of risk of recurrence of symptoms, Emergency Department re-admissions, level of impairment, and school absenteeism. We identified 761 children who visited our ED with the chief complaint of chest pain, equal to 0.68% of all admissions. Twenty-four patients were excluded for a previous history of cardiac disease. Eight (1%) patients were determined to have chest pain of cardiac origin. Ninety-seven percent of patients were successfully contacted by telephone: 69% agreed to answer the questionnaire. Of these, 33% experienced recurrent chest pain, up to 41% was forced to be absent from school, about 20% was limited in its daily activities, and about 20% repeated a cardiologic evaluation.Conclusion: Chest pain is mainly due to benign causes and is a recurrent symptom in a high percentage of patients, associated with re-admission and school absenteeism.What is Known:• Chest pain is a relatively common cause of admission to the Emergency Department.• It is mainly due to benign causes and is among the most common reasons for referral to the pediatric cardiologist.What is New:• Chest pain is a recurrent symptom associated with re-admission and school absenteeism.• As a family history of cardiac disease or exertional symptoms are a well-known red flag for chest pain of cardiac origin, school absenteeism should be considered a red flag for symptoms related to psychological distress in patients with non-cardiac chest pain.

Takotsubo cardiomyopathy is rather rare entity among patients on hemodialysis with very few cases reported in the literature to date. This syndrome is characterized with transient left ventricular dysfunction and apical motion abnormality with the absence of coronary artery disease and by clinical features it is mimicking acute coronary syndrome. It almost always follows high level of emotional or physical stress. Although rarely described, it should be considered as a differential diagnosis in patients on hemodialysis presenting with the symptoms of acute coronary syndrome, especially in the setting of acute stress. It is possible the condition is underdiagnosed giving the wide range of its clinical presentations. To the best of our knowledge there are 11 cases and here we present 12th case and the review of the literature. [ABSTRACT FROM AUTHOR]

The aims of this study are (1) to evaluate the performance of current triage for chest pain; (2) to describe the case mix of patients undergoing triage for chest pain; and (3) to identify opportunities to improve performance of current Dutch triage system for chest pain. Chest pain is a common symptom, and identifying patients with chest pain that require urgent care can be quite challenging. Making the correct assessment is even harder during telephone triage. Temporal trends show that the referral threshold has lowered over time, resulting in overcrowding of first responders and emergency services. While various stakeholders advocate for a more efficient triage system, careful evaluation of the performance of the current triage in primary care is lacking. TRiage of Acute Chest pain Evaluation in primary care (TRACE) is a large cohort study designed to describe the current Dutch triage system for chest pain and subsequently evaluate triage performance in regard to clinical outcomes. The study consists of consecutive patients who contacted the out-of-hours primary care facility with chest pain in the region of Alkmaar, the Netherlands, in 2017, with follow-up for clinical outcomes out to August 2019. The primary outcome of interest is 'major event', which is defined as the occurrence of death from any cause, acute coronary syndrome, urgent coronary revascularization, or other high-risk diagnoses in which delay is inadmissible and hospitalization is necessary. We will evaluate the performance of the triage system by assessing the ability of the triage system to correctly classify patients regarding urgency (accuracy), the proportion of safe actions following triage (safety) as well as rightfully deployed ambulances (efficacy). TRACE is designed to describe the current Dutch triage system for chest pain in primary care and to subsequently evaluate triage performance in regard to clinical outcomes. [ABSTRACT FROM AUTHOR]

Background: To assess the efficacy and safety of oral Guanxinshutong (GXST) capsules in Chinese patients with stable angina pectoris (SAP) in a prospective, multicenter, double-Blind, placebo-controlled, randomized clinical trial (clinicaltrials.gov Identifier: NCT02280850). Methods: Eligible patients were randomized 1:1 to the GXST or placebo group. Current standard antianginal treatment except for nitrate drugs was continued in both groups, who received an additional 4-week treatment of GXST capsule or placebo. Primary endpoint was the change from baseline in angina attack frequency after the 4-week treatment. Secondary endpoints included the reduction of nitroglycerin dose, score of Seatntle Agina Questionnaire, exercise tolerance test defined as time to onset of chest pain and ST-segment depression at least 1 mm greater than the resting one. Results: A total of 300 SAP patients from 12 centers in China were enrolled between January 2013 and October 2015, and they were randomly divided into the GXST group and the placebo group (150 patients in each group). Of whom, 287 patients completed the study (143 patients in the GXST group, 144 patients in the placebo group). The baseline characteristics of the two groups were comparable. After 4-week treatment with GXST capsules, the number of angina attacks and the consumption of short-acting nitrates were significantly reduced. In addition, the quality of life of patients were also substantially improved in the GXST group. No significant differences in the time of onset of angina and 1-mm ST segment depression were noted between the two groups. 7 patients (4.1%) in the GXST group and 3 patients (2.1%) in the placebo group reported at least one adverse event, respectively. Conclusions: GXST capsules are beneficial for the treatment of SAP patients. [ABSTRACT FROM AUTHOR]
