BACKGROUND: Identifying predictors of coronary artery disease (CAD)-related procedures and events remains a priority. METHODS: We measured an age- and sex-specific gene expression score (ASGES) previously validated to detect obstructive CAD (oCAD) in symptomatic nondiabetic patients in the PROMISE trial. The outcomes were oCAD (≥70% stenosis in ≥1 vessel or ≥50% left main stenosis on CT angiography [CTA]) and a composite endpoint of death, myocardial infarction, revascularization, or unstable angina...

We present a case of a 66-year-old lady with chest pain, without dynamic 12-lead electrocardiographic (ECG) changes and normal serial troponin. Coronary angiography revealed a linear filing defect in the first obtuse marginal branch of the circumflex artery indicating coronary artery dissection, with superadded thrombus. She was managed medically with dual antiplatelet therapy and has responded well. Spontaneous coronary artery dissection (SCAD) is a rare cause of cardiac chest pain, which can be missed without coronary angiography...

BACKGROUND: The bench press exercise (BP) plays an important role in recreational and professional training, in which muscle activity is an important multifactorial phenomenon. The objective of this paper is to systematically review electromyography (EMG) studies performed on the barbell BP exercise to answer the following research questions: Which muscles show the greatest activity during the flat BP? Which changes in muscle activity are related to specific conditions under which the BP movement is performed? STRATEGY: PubMed, Scopus, Web of Science and Cochrane Central Register of Controlled Trials (CENTRAL) in the Cochrane Library were searched through June 10, 2016...

BACKGROUND: Cardiac troponin (T and I) are considered the standard markers for detection of myocardial damage and the diagnosis of acute coronary syndrome (ACS) among patients who present to an emergency department with chest pain. However, these markers can be released in other situations and may be associated with short- and long-term clinical outcomes. In this study, we examine late mortality rates among patients presenting with a suspected ACS due to an unstable coronary plaque and those patients having a non-ACS...

BACKGROUND: Homocysteine (Hcy) has been considered as an independent risk factor for coronary artery disease (CAD). Folic acid and vitamin B12 are two vital regulators in Hcy metabolic process. We evaluated the correlations between serum Hcy, folic acid and vitamin B12 with the categories of CAD. METHODS: Serum Hcy, folic acid and vitamin B12 from 292 CAD patients, including 73 acute myocardial infarction (AMI), 116 unstable angina pectoris (UAP), 103 stable angina pectoris (SAP), and 100 controls with chest pain patients were measured, and the data were analyzed by SPSS software...

BACKGROUND AND AIMS: Typical angina pectoris (AP) and high-sensitive troponin I (hs-TnI) are independently associated with coronary artery disease (CAD) and future cardiovascular events (CVE). This study aimed to assess the individual and combined diagnostic and prognostic impact of symptoms and hs-TnI in stable chest pain patients without prior cardiovascular disease. METHODS: During a one-year period, 487 patients with suspected stable AP underwent invasive or CT-coronary angiography (significant stenosis ≥50%)...

Because of the life-threatening character and a high prevalence in emergency rooms, cardiac causes are important differential diagnoses of acute chest pain with the need for rapid clarification. In this context the working diagnosis "acute coronary syndrome" (ACS) plays a major role. In a synopsis of the clinical presentation, medical history, electrocardiogram and analysis of cardiac biomarkers, ST-segment elevation myocardial infarction (STEMI), non-ST-segment elevation myocardial infarction (NSTEMI) and unstable angina pectoris can be specified as entities of ACS...

A 53-year-old man arrived at the trauma center with a steel bar penetrating from the epigastrium to the right scapula. He was hypotensive and hypoxic, and immediate resuscitation and basic evaluation were performed. An emergency operation was performed due to an unstable hemodynamic state. Multiple injuries were confirmed in the right lower lobe, posterior chest wall, diaphragm, and liver lateral segment. Right lower lobectomy and liver lateral sectionectomy were performed following removal of the bar. The patient recovered without additional hemorrhage after the surgery, and was transferred to a rehabilitation institution with periodic follow-up...

REVIEW
Tamas F Molnar
Clinical suspicion of hemo/pneumothorax: when in doubt, drain the chest. Stable chest trauma with hemo/pneumothorax: drain and wait. Unstable patient with dislocated trachea must be approached with drain in hand and scalpel ready. Massive hemo/pneumothorax may be controlled by drainage alone. The surgeon should not hesitate to open the chest if too much blood drains over a short period. The chest drainage procedure does not end with the last stitch; the second half of the match is still ahead. The drained patient is in need of physiotherapy and proper pain relief with an extended pleural space: control the suction system...

BACKGROUND: Coronary artery anomalies are a heterogeneous group of congenital disorders presenting with a wide spectrum of symptoms, ranging from vague chest pain to sudden cardiac death. Despite available data, there is no consensus about the classification, nomenclature, and outcomes of coronary anomalies in the normally connected heart. In this study, we aimed to investigate clinical and angiographic characteristics of coronary arterial anomalies, as well as the frequency of atherosclerotic involvement in anomalous coronaries, diagnosed at a tertiary referral centre...

OBJECTIVES: The electrocardiograph (ECG) is an essential tool in initial management and risk stratification of patients with suspected acute coronary syndrome (ACS). A six-point reporting criterion has been proposed to facilitate standardized clinical assessment of patients presenting to the emergency department (ED) with suspected ACS. We set out to evaluate the efficacy of these criteria in identifying patients with major adverse cardiac events (MACE), Type 1 myocardial infarction (T1MI), Type 2 myocardial infarction (T2MI), and one-year mortality in a cohort of emergency patients with chest pain...

A 29 year male, with an inoperable adenocarcinoma of gall bladder was initiated on gemcitabine and a platinum compound based chemotherapy. During 4th cycle of chemotherapy, patient complained of chest pain following cisplatin and gemcitabine infusion. ECG was suggestive of acute coronary syndrome, which was successfully managed by antianginal therapy. Fifth cycle of chemotherapy was uneventful. Patient died of cardiovascular collapse before receiving the 6th cycle of chemotherapy. As per Naranjo adverse drug reaction probability scale, causal association of the event with cisplatin and gemcitabine was probable and possible respectively...

We present a patient with asymptomatic apical hypertrophic cardiomyopathy (AHCM) who recently developed cardiac arrhythmias, and shortly discuss the diagnostic modalities, differential diagnosis, and treatment strategy for this condition. AHCM is a rare form of hypertrophic cardiomyopathy, which usually involves the apex of the left ventricle. AHCM can occur with varied presentations such as chest pain, palpitations, dyspnea, syncope, atrial fibrillation, myocardial infarction, embolic events, ventricular fibrillation, and congestive heart failure...

The prognostic implications of myocardial computed tomography perfusion (CTP) analyses are unknown. In this sub-study to the CATCH-trial we evaluate the ability of adenosine stress CTP findings to predict mid-term major adverse cardiac events (MACE). In 240 patients with acute-onset chest pain, yet normal electrocardiograms and troponins, a clinically blinded adenosine stress CTP scan was performed in addition to conventional diagnostic evaluation. A reversible perfusion defect (PD) was found in 38 patients (16 %) and during a median follow-up of 19 months (range 12-22 months) 25 patients (10 %) suffered a MACE (cardiac death, non-fatal myocardial infarction and revascularizations)...

PURPOSE: The aim of the study was to assess the task-specificity (greater improvements in trained compared to non-trained tasks), transferability and time-course adaptations of resistance-training programs with varying instability requirements. METHOD: Thirty-six resistance-trained men were randomized to train chest press 2 days week(-1) for 10 week (6 repetitions × 4 series) using a Swiss ball, Smith machine or dumbbells. A six-repetition maximum-strength test with the aforementioned exercises and traditional barbell chest press were performed by all participants at the first, 7th, 14th and final training session in addition to electromyographic activities of the prime movers measured during isometric bench press...

Decision-making in acute chest pain remains challenging despite normal (below ninety-ninth percentile) high-sensitivity troponin (hs-cTn). Some studies suggest that undetectable hs-cTn, far below the ninety-ninth percentile, might rule out acute coronary syndrome. We investigated clinical data in comparison to undetectable hs-cTnT. The study comprised 682 patients (November 2010 to September 2011) presenting at the emergency department with chest pain and normal hs-cTnT (<14 ng/l). The main end point was major adverse cardiac events (MACE: death, myocardial infarction, readmission for unstable angina, or revascularization) at a 4-year median follow-up; secondary end point was 30-day MACE...

BACKGROUND: Since year 2000, reducing hospital readmissions has become a public health priority. In addition, there have been major changes in percutaneous coronary intervention (PCI) during this period. METHODS: The cohort consisted of 3,250,194 patients admitted for PCI from January 2000 through November 2012. RESULTS: Overall, 30-day readmission was 15.8%. Readmission rates declined from 16.1% in 2000 to 15.4% in 2012 (adjusted odds ratio for readmission 1...
