BACKGROUND: Only a small fraction of acute chest pain in the emergency department (ED) is due to obstructive coronary artery disease (CAD). ED chest pain remains associated with high rates of recidivism, often in the presence of nonobstructive CAD. Psychological states such as depression, anxiety, and elevation of perceived stress may account for this finding. The objective of the study was to determine whether psychological states predict recurrent chest pain (RCP). METHODS: We conducted a prospective cohort study of low- to moderate-cardiac risk ED patients admitted to the Yale Chest Pain Center with acute chest pain...

Neurologic stunned myocardium (NSM) is a phenomenon where neurologic events give rise to cardiac abnormalities. Neurologic events like stroke and seizures cause sympathetic storm and autonomic dysregulation that result in myocardial injury. The clinical presentation can involve troponin elevation, left ventricular dysfunction, and ECG changes. These findings are similar to Takotsubo cardiomyopathy and acute coronary syndrome. It is difficult to distinguish NSM from acute coronary syndrome based on clinical presentation alone...

INTRODUCTION: High-sensitivity cardiac troponin assays have significantly improved the sensitivity of myocardial infarction detection by using cutoff values and early absolute changes. However, variation in repeated measures also depends on biological variability. This study aimed to assess the potential circadian component of this biological variability. METHODS: 17 healthy volunteers were recruited, and standardized conditions for physical activity, meals, exposure to light and duration of sleep were imposed...

High-sensitivity cardiac troponin assay development enables determination of biological variation in healthy populations, more accurate interpretation of clinical results and points towards earlier diagnosis and rule-out of acute myocardial infarction. In this paper, we report on preliminary tests of an immunoassay analyzer employing an optimized LED excitation to measure on a standard troponin I and a novel research high-sensitivity troponin I assay. The limit of detection is improved by factor of 5 for standard troponin I and by factor of 3 for a research high-sensitivity troponin I assay, compared to the flash lamp excitation...

BACKGROUND Pulmonary arterial hypertension (PAH) results from proliferative vasculopathy involving all layers of the blood vessel. Similar findings may be present in pulmonary hypertension (PH) associated with microscopic tumor embolism, which are thought to be related to the phenomenon of pulmonary tumor thrombotic microangiopathy (PTTM). PTTM is associated with the activation of the coagulation system at the surface of the tumor emboli, resulting in stenosis or occlusion of the vessel. CASE REPORT A 49-year-old man with stage IV gastro-esophageal junction adenocarcinoma presented with complaints of cough and shortness of breath...

The recent approval of the 5(th) generation cTnT assay which has characteristics clinically of a high sensitivity assay has led to concern that the problems of increased sensitivity will be greater than the benefits. This will not be the case if Cardiology, Emergency Medicine and Laboratory Medicine combine to develop procedures for use of the assay. We advocate sex specific 99(th)% upper reference limit (URL) values of 15ng/L for men and 10ng/L for women. We suggest a 2 hour rule out strategy including a value less than the 99(th)% URL and the lack of a change in values of <4 ng/L...

BACKGROUND: The American Heart Association and European Resuscitation Council guidelines for cardiopulmonary resuscitation present rules for termination of resuscitation (TOR) in cases of out-of-hospital cardiac arrest (OHCA). In Japan, only doctors are legally allowed TOR in OHCA cases. OBJECTIVE: This study aimed to develop a new TOR rule that suits the actual situations of the Japanese emergency medical services system. METHODS: Five different combinations of the TOR rule criteria were compared regarding specificity and positive predictive value (PPV) for 1-month survival with unfavorable neurologic outcomes...

In heart transplantation (HTx) patients, routine surveillance endomyocardial biopsies (rsEMB) are recommended for the detection of early cardiac allograft rejection. However, there is no consensus on the optimal frequency of rsEMB. Frequent rsEMB have shown a low diagnostic yield in the new era of potent immunosuppressive regimen. Efficacy and safety of lower frequency rsEMB have not been investigated so far. In this retrospective, single centre, observational study we evaluated 282 patients transplanted between 2004 and 2014...

Patients with solid-organ transplants usually present at the emergency department with nonspecific symptoms. The physician should consider a great variety of syndromes and diseases, given the greater risk that solid-organ transplant patients carry because of immunosuppression and transplant-related conditions. Myocardial infarction caused by cardiac allograft vasculopathy must be always suspected and ruled out, even when initial symptoms do not orientate in that direction. We present a case that conjugates signs that can be present in different pathologies...

High-sensitivity cardiac troponin (hs-cTn) assays have been used clinically by thousands of physicians in many countries throughout the world since their clinical introduction 7 years ago. In the early diagnosis of myocardial infarction (MI), beyond doubt, the most important indication of hs-cTn assays, these simple, inexpensive, and highly reproducible tools complement detailed clinical assessment including chest pain characteristics and the electrocardiogram. Hs-cTn assays for the first time allowed the precise quantification of cardiomyocyte injury around the 99th percentile and thereby substantially increased the accuracy of MI detection from blood obtained at presentation to the emergency department (ED)...

Prevalence of cardiac and liver iron overload in patients with thalassemia in real-world practice may vary among different regions especially in the era of widely-used iron chelation therapy. The aim of this study was to determine the prevalence of cardiac and liver iron overload in and the management patterns of patients with thalassemia in real-world practice in Thailand. We established a multicenter registry for patients with thalassemia who underwent magnetic resonance imaging (MRI) as part of their clinical evaluation...

We report the case of an 18-year-old woman with personality disorders who was hospitalized a few hours after suicidal ingestion of acetaminophen, quetiapine, acetylsalicylic acid, and ethanol. Twelve hours after admission, severe liver damage was evident, but the patient was stable and awaiting hepatic transplantation. Electrolytes were successfully controlled. The condition of the liver stabilized. Cardiac biomarkers then deteriorated unexpectedly. Localized ST-segment elevations were noted on electrocardiogram, but angiography ruled out myocardial infarction...

While there is evidence for cardiac arrhythmias associated with macrolide and fluoroquinolone antibiotics, there is still debate among health care providers as to whether this risk of arrhythmia is overstated. A joint panel of the US Food and Drug Administration suggested that macrolide and fluoroquinolone labels need much stronger warnings regarding the possible serious adverse cardiac effects associated with these antibiotics, especially since they are so widely prescribed. And while health care providers may differ on the pertinence of the cardiac risks associated with antibiotic use, they can undoubtedly minimize the cardiac effects that are associated with these antibiotics by paying attention to the cardiac risk factors and drug history associated with the patient...

The earliest biomarkers introduced to diagnose myocardial infarction (MI) such as aspartate aminotransferase (AST) and lactic dehydrogenase (LDH) lacked cardiac specificity and were replaced by creatine kinase (CK), the CK-MB isoenzyme, and ultimately the cardiac-specific troponins (cTnT and cTnI). This has opened up the possibilities of ruling out MI more rapidly and also identifying patients with a chronic elevation of cTn and a poor prognosis in a range of cardiac conditions.

OBJECTIVE: Admission to the chest pain observation unit (CPOU) may be an advantageous time for patients to consider heart-healthy lifestyle changes while undergoing diagnostic evaluation to rule out myocardial ischemia. The aim of this pragmatic trial was to assess the effectiveness of a multiple risk factor intervention in changing CPOU patients' health beliefs and readiness to change health behaviors. A secondary aim was to obtain preliminary estimates of the intervention's effect on diet, physical activity, and smoking...

BACKGROUND: Despite improvements in identifying high-risk patients with non-ST segment ACS (acute coronary syndrome), low risk patients presenting with atypical chest pain and non-diagnostic Electrocardiogram (ECG) continued to undergo unnecessary admissions and testing. Since 1992, our chest pain protocol included using 4-hour serial biomarkers from ED admission in combination with stress testing to evaluate these patients. Our study aimed at determining whether a new accelerated diagnostic protocol using sensitive cardiac troponin I (cTnI) 2 hours after admission to the ED followed by stress testing is safe and effective in emergency settings, allowing for appropriate triage, earlier discharge and reducing costs...
