INTRODUCTION ---Acute pericarditis is the most commonly encountered manifestation of pericardial disease (incidence: 0.2 percent to 0.5 percent in hospitalized patients). However, data regarding manifestations, workup, and the management of acute pericarditis in the African American population is lacking. This study aims to collect and analyze more clinical data related to acute pericarditis in this understudied population. METHODOLOGY We conducted a retrospective chart review of all patients managed for acute pericarditis at a university hospital serving a predominantly African American population...

BACKGROUND: Many health systems rely on helicopter EMS (HEMS) to transfer ST-elevation myocardial infarction (STEMI) patients for percutaneous coronary intervention (PCI) to a hospital with a catheterization laboratory. Mortality rates increase with the time to reperfusion, so reducing delays is imperative. For interhospital STEMI transfers, the time spent in the initial hospital from arrival until departure (door-in to door-out interval or DIDO) should be minimized. OBJECTIVE: To evaluate the impact of a series of process improvements to reduce DIDO intervals for STEMI patients transferred via a hospital based HEMS program...

In COPD, pulmonary hyperinflation causes decreased stroke volume thereby decreased oxygen pulse (O2P). While O2P flattening is related to myocardial ischemia in cardiac patients, O2P patterns have seldom been explored in COPD. The aims of the study were to investigate O2P-curve patterns and associated factors in COPD. Seventy-five patients with stable COPD were enrolled. The demographics, cardiac size, physiological measurements and stress EKG were compared among O2P-curve pattern groups. An algorithm to identify O2P-curve patterns was developed in 28 patients...

REVIEW

Acute heart failure (AHF) patients rarely present complaining of 'acute heart failure.' Rather, they initially present to the emergency department (ED) with a myriad of chief complaints, symptoms, and physical exam findings. Such heterogeneity prompts an initially broad differential diagnosis; securing the correct diagnosis can be challenging. Although AHF may be the ultimate diagnosis, the precipitant of decompensation must also be sought and addressed. For those AHF patients who present in respiratory or circulatory failure requiring immediate stabilization, treatment begins even while the diagnosis is uncertain...

INTRODUCTION: We hypothesized that very high-density mapping of typical atrial flutter (AFL) would facilitate a more complete understanding of its circuit. Such very high-density mapping was performed with the Rhythmia(TM) (Boston Scientific) mapping system using its 64 electrode basket catheter. METHODS AND RESULTS: Data were acquired from 13 patients in AFL. Functional anatomy of the right atrium (RA) was readily identified during mapping including the Crista Terminalis and Eustachian ridge...

A 50-year-old male with a history of hemodialysis dependent chronic kidney disease presented to our emergency department with acute midsternal crushing chest pain. Patient was diagnosed with acute anterolateral wall Myocardial Infraction due to the presence of corresponding ST segment elevations in EKG and underwent emergent cardiac catheterization which revealed normal patent coronaries without any disease. He continued to have chest pain for which CT of the chest was done which revealed pneumomediastinum with mediastinal hematoma, due to the recent attempted thrombectomy for thrombus in his right brachiocephalic vein...

Sudden unexpected death in epilepsy (SUDEP) is the leading cause of death in refractory epilepsy patients. While specific mechanisms underlying SUDEP are not well understood, evidence suggests most SUDEP occurs due to seizure-induced respiratory arrest. SUDEP also tends to happen at night. While this may be due to circumstances humans find themselves in at night, such as being alone without supervision or sleeping prone, or due to independent influences of sleep state, there are a number of reasons why the night (i...

China is a country with vast territory, but economic development and population growth have reduced the usable land resources in recent years. Therefore, reclamation by pumping and filling is carried out in eastern coastal regions of China in order to meet the needs of urbanization. However, large areas of reclaimed land need rapid drainage consolidation treatment. Based on past researches on how to improve the treatment efficiency of soft clay using vacuum preloading combined with electro-osmosis, a two-dimensional drainage plane model was proposed according to the Terzaghi and Esrig consolidation theory...

The GERS (Exercise Rehabilitation and Sports Group of the French Society of Cardiology) has decided to update current guidelines regarding the practice of EKG stress tests. Since the last update dates from 1997, the GERS judged it necessary to integrate data from new works and advancements made in the last 20 years. Good clinical practices and safety conditions are better defined regarding the structure, location, material, staff competency, as well as convention with hospital structures. The diagnosis of coronary artery disease remains the principal indication for a stress test...

Lyme disease is caused by the spirochete Borrelia burgdorferi and is carried to human hosts by infected ticks. There are nearly 30,000 cases of Lyme disease reported to the CDC each year, with 3-4% of those cases reporting Lyme carditis. The most common manifestation of Lyme carditis is partial heart block following bacterial-induced inflammation of the conducting nodes. Here we report a 45-year-old gentleman that presented to the hospital with intense nonradiating chest pressure and tightness. Lab studies were remarkable for elevated troponins...

Obstructive sleep apnoea (OSA) is frequently undiagnosed in patients with heart failure (HF) and coronary artery disease (CAD). Simple and widely available screening tests are needed to diagnose patients with SA. Measurements of thoracic impedance and heart rate variability during 24-hour ECG Holter (H-EKG) monitoring allows to calculate estimated apnoea-hypopnoea index (eAHI). AIM: The aim of the research was to assess prevalence of OSA evaluated with the use of H-EKG and determination of its clinical relevance in patients with CAD and ischeamic HF...

Arrhythmogenic Right Ventricular Cardiomyopathy (ARVC) is a relatively under-recognized hereditary cardiomyopathy. It is characterized pathologically by fibro-fatty infiltration of right ventricular (RV) myocardium and clinically by consequences of RV electrical instability. Timely intervention with device therapy and pharmacotherapy may help reduce the risk of arrhythmic events or sudden cardiac death. Here, we describe a classic case of a young adult with ARVC and a brief literature review. The patient presented with exertional palpitations and ARVC was suspected after his routine electrocardiogram (EKG) revealed symmetric T wave inversions and possible epsilon waves in right precordial leads...

Sudden unexpected death in epilepsy (SUDEP) is one of the most frequent causes of death among patients with epilepsy. Most SUDEP or near-SUDEP are unwitnessed and not observed or recorded during video-EEG recording in epilepsy monitoring units. This report describes a young woman with post ictal apnea and generalized EEG suppression (PGES) after a secondary generalized tonic-clonic seizure (sGTCS). This was accompanied by bradycardia and then ventricular tachycardia (VT). But at the end of VT, the patient's breath recovered without any intervention, such as cardio-respiratory resuscitation...
