Cardiac chest pain best practice

At the emergency department (ED), it is important to quickly and accurately determine which patients are likely to have a major adverse cardiac event (MACE). Machine learning (ML) models can be used to aid physicians in detecting MACE, and improving the performance of such models is an active area of research. In this study, we sought to determine if ML models can be improved by including a prior electrocardiogram (ECG) from each patient. To that end, we trained several models to predict MACE within 30 days, both with and without prior ECGs, using data collected from 19,499 consecutive patients with chest pain, from five EDs in southern Sweden, between the years 2017 and 2018...

BACKGROUND: Isolated membranous ventricular septal aneurysms are infrequent in clinical practice. Furthermore, current guidelines do not dictate how to diagnose or manage such lesions. CASE SUMMARY: A 54-year-old male patient with a history of essential hypertension and tobacco use presented with chest pain associated with dyspnoea and nausea. Electrocardiogram was unrevealing. Physical exam was significant for a diastolic murmur heard best in the apex. Computed tomography angiography of the chest revealed an aneurysm measuring 5 cm in diameter along the ascending aorta...

Pericarditis and myocarditis represent a challenging set of diseases to diagnose and treat. These diseases typically present with chest pain and dyspnea in previously healthy young people, often in the weeks following a viral illness, including COVID-19. Nonetheless, the etiologies can be very diverse, including infectious, noninfectious, drug-induced, and autoimmune causes. This review focuses on the evaluation, diagnosis, and management of emergency department patients presenting with pericarditis and myocarditis and summarizes current guidelines and best-practice medical management strategies in order to avoid potential life-threatening cardiac complications...

Vaccination remains the best strategy against coronavirus disease 2019 (COVID-19) in terms of prevention. The efficacy and safety of COVID-19 vaccines is supported by well-designed clinical trials that recruited many participants. It is well-known that vaccination is associated with local side effects related to the injection site, and mild, systemic side effects. However, there has been an increase in the occurrence of what is known as infrequent adverse effects in the population of vaccinated individuals in real life...

PURPOSE OF REVIEW: Regional anesthesia is gaining attention as a valuable component of multimodal, opioid-sparing analgesia in cardiac surgery, where improving the patient's quality of recovery while minimizing the harms of opioid administration are key points of emphasis in perioperative care. This review serves as an outline of recent advancements in a variety of applications of regional analgesia for cardiac surgery. RECENT FINDINGS: Growing interest in regional analgesia, particularly the use of newer "chest wall blocks", has led to accumulating evidence for the efficacy of multiple regional techniques in cardiac surgery...

The 2021 American Heart Association/American College of Cardiology/American Society of Echocardiography/American College of Chest Physicians/Society for Academic Emergency Medicine/Society of Cardiovascular Computed Tomography/Society for Cardiovascular Magnetic Resonance guidelines for the evaluation and diagnosis of acute chest pain make important recommendations that include the recognition of high-sensitivity cardiac troponin (hs-cTn) as the preferred biomarker, endorsement of 99th percentile upper reference limits to define myocardial injury, and the use of clinical decision pathways, as well as acknowledgment of the uniqueness of women and other patient subsets...

BACKGROUND & AIMS: As many as one-half of all patients with suspected gastroesophageal reflux disease (GERD) do not derive benefit from acid suppression. This review outlines a personalized diagnostic and therapeutic approach to GERD symptoms. METHODS: The Best Practice Advice statements presented here were developed from expert review of existing literature combined with extensive discussion and expert opinion to provide practical advice. Formal rating of the quality of evidence or strength of recommendations was not the intent of this clinical practice update...

Post-acute coronavirus disease 2019 (COVID-19) syndrome is a novel, poorly understood clinical entity with life-impacting ramifications. Patients with this syndrome, also known as "COVID-19 long-haulers," often present with nonspecific ailments involving more than one body system. The most common complaints include dyspnea, fatigue, brain fog, and chest pain. There currently is no single agreed-upon definition for post-acute COVID-19 syndrome, but most agree that criterion for this syndrome is the persistence of mental and physical health consequences after initial infection...

BACKGROUND: Chest pain is among the most common presenting complaints in the emergency department (ED). Swift and accurate risk stratification of chest pain patients in the ED may improve patient outcomes and reduce unnecessary costs. Traditional logistic regression with stepwise variable selection has been used to build risk prediction models for ED chest pain patients. In this study, we aimed to investigate if machine learning dimensionality reduction methods can improve performance in deriving risk stratification models...

Millions of patients present to US EDs each year with symptoms concerning for acute coronary syndrome (ACS), but fewer than 10% are ultimately diagnosed with ACS. Well-tested and externally validated accelerated diagnostic protocols were developed to aid providers in risk stratifying patients with possible ACS and have become central components of current ED practice guidelines. Nevertheless, the fear of missing ACS continues to be a strong motivator for ED providers to pursue further testing for their patients...

The use of diagnostic radiography has doubled in the past two decades. Image Gently (children) and Image Wisely (adults) are multidisciplinary initiatives that seek to reduce radiation exposure by eliminating unnecessary procedures and offering best practices. Patients with an estimated glomerular filtration rate less than 30 mL per minute per 1.73 m2 may have increased risk of nephropathy when exposed to iodinated contrast media and increased risk of nephrogenic systemic fibrosis when exposed to gadolinium-based contrast agents...

BACKGROUND: Over the past decade, intense collaboration between academic investigators and the diagnostic industry have allowed the integration of high-sensitivity cardiac troponin (hs-cTn) assays into clinical practice worldwide. The hs-cTn assays, with their increased diagnostic accuracy for acute myocardial infarction (AMI), have facilitated the maturation of early rule-out strategies. The first iteration was complex and required the combination of a biomarker panel, the electrocardiogram, and a clinical risk score and allowed the safe rule-out of AMI in only 10% of patients with acute chest pain...

CONTEXT: As the number of transgender (trans) people (including those who are binary and/or nonbinary identified) seeking gender-affirming hormone therapy rises, endocrinologists are increasingly asked to assist with interpretation of laboratory tests. Many common laboratory tests such as hemoglobin, iron studies, cardiac troponin, and creatinine are affected by sex steroids or body size. We seek to provide a summary of the impact of feminizing and masculinizing hormone therapy on common laboratory tests and an approach to interpretation...

BACKGROUND: Kennedy's disease (KD), also known as spinal and bulbar muscular atrophy (SBMA), is a rare, adult-onset, X-linked recessive neuromuscular disease caused by CAG expansions in exon 1 of the androgen receptor gene (AR). The objective of the French national diagnostic and management protocol is to provide evidence-based best practice recommendations and outline an optimised care pathway for patients with KD, based on a systematic literature review and consensus multidisciplinary observations...

In 2008, the German Cardiac Society (GCS) introduced a certification program for specialized chest pain units (CPUs). In order to benchmark the performance of the certified CPUs, a nationwide German CPU registry was established. Since then, data for more than 34,000 patients have been included. The concept of certified CPUs in Germany has been widely accepted and its success is underlined by its recent inclusion in national and international guidelines. As of December 2019, 286 CPUs have been successfully certified or recertified by the GCS...

Determining the underlying etiology of chest pain remains a mainstay of modern cardiological practice and is focused on identifying coronary artery disease to improve both symptoms and prognosis. In the current age of multi-modality imaging, the expanding repertoire of tests has subjected clinicians to a tyranny of choices. In whom should we perform further investigations? What non-invasive modality should be used? Which test is the best gatekeeper for invasive coronary angiography? In this week's American Heart Journal, Houssany-Pissot and colleagues present real-world data from a large French cohort of patients who present with suspected stable coronary artery disease undergoing invasive coronary angiography...

Current advanced cardiac life support (ACLS) guidelines for the management of ventricular fibrillation (VF) and pulseless ventricular tachycardia is defibrillation. However, refractory VF, which is defined as VF that persists despite three defibrillation attempts, is challenging for all ACLS providers; the best resuscitation strategy for patients that persist in refractory VF remains unclear. We report on a 51-year-old man who presented to the emergency department with chest pain and subsequently went into witnessed VF cardiac arrest...

BACKGROUND: Takotsubo syndrome (TTS) is an acute cardiac condition with reversible heart failure which is often triggered by psychological and physical stressful events. Although pulmonary embolism (PE) was reported as a trigger for TTS, the concurrence of TTS and PE has been rarely reported, let alone that triggered by PE. Here we describe a case of a postmenopausal female presenting with symptoms similar to myocardial ischemia, which may be caused by PE, and review the available literature that may help clinicians with their practice to similar situations since no published guidelines are available...

A novel approach to advanced electronic health record (EHR) skills training was developed in a large healthcare organization to improve high-quality EHR documentation, while reducing stressors linked to physician burnout.The 3-day intensive EHR education intervention covered best practices in EHR documentation and physician well-being. The specialty physician faculty used interactive teaching including demonstration, facilitation, and individual coaching. Laptops were provided for hands-on practice. Mixed-method evaluation included real-time feedback, daily surveys, and post-activity surveys to measure participant learning and satisfaction, and also collection of performance data from the EHR to measure use of order sets designed to improve quality of care...

This article synthesizes current best evidence for the evaluation of patients with suspected acute coronary syndrome (ACS) using high-sensitivity troponin assays, enabling physicians to effectively incorporate them into practice. Unlike conventional assays, high-sensitivity assays can precisely measure blood cardiac troponin concentrations in the vast majority of healthy individuals, facilitating the creation of rapid diagnostic algorithms. Very low troponin concentrations on presentation accurately rule out acute myocardial infarction (AMI) and enable the discharge of approximately 20% of patients after a single test, whereas an additional 30%-40% of patients can be safely discharged after short-interval serial sampling in as little as 1 or 2 hours...
