Cardiovascular imaging imparts a huge burden on healthcare spending. Coronary CT angiography (CCTA) may provide a cost effective means of diagnosing coronary artery disease (CAD) and reducing downstream cost of testing. We performed a systematic search of literature for randomized controlled trials or prospective or retrospective non-randomized comparative studies or case series, decision analytic models and technology reports in which some or all of the patients underwent CCTA and looking at the cost effectiveness, comparative effectiveness and downstream test utilization associated with the use of CCTA...

Stratifying risk of patients with acute coronary syndrome (ACS) in the emergency department (ED) remains a frequent challenge. When ST-elevation criteria are absent, current recommendations rely upon insensitive and time-intensive methods such as the electrocardiogram and cardiac enzyme testing. Here, we report on a series of cases, where emergency physicians used a simplified model for identifying regional wall motion abnormalities by point-of-care echocardiography in patients presenting with chest pain to the ED...

Clinical questionIs a vasopressin, steroid, and epinephrine (VSE) protocol for in-hospital cardiac arrest resuscitation associated with better survival to hospital discharge with favourable neurologic outcome compared to epinephrine alone?Article chosenMentzelopoulos S, Malachias S, Konstantopoulos D, et al. Vasopressin, steroids, and epinephrine and neurologically favorable survival after in-hospital cardiac arrest: a randomized clinical trial.JAMA 2013;310:270-9.ObjectiveTo determine if a VSE protocol during cardiopulmonary resuscitation with hydrocortisone administration in patients with postresuscitative shock at 4 hours after return of spontaneous circulation would improve survival to hospital discharge with favourable neurologic outcome...

Background and Scope. Early etiologic diagnosis of ischemic stroke subtype guides acute management and treatment. We aim to evaluate if plasma biomarkers can predict stroke subtypes in the early phase from stroke onset. Methods. Plasma N-terminal prohormone of brain natriuretic peptide (NT-proBNP), D-dimer, C-reactive protein, serum albumin, and globulin levels have been investigated in 114 consecutive patients presenting at the emergency room within 6 hours of the ischemic stroke onset. Plasma levels of biomarkers have been correlated with stroke aetiology (based on TOAST criteria) by multivariable logistic regression analysis, adjusted for several covariates...

In the normal course of the delivery of care, anesthesiologists encounter many patients who are receiving drugs that affect platelet function as a fundamental part of primary and secondary management of atherosclerotic thrombotic disease. There are several antiplatelet drugs available for use in clinical practice and several under investigation. Aspirin and clopidogrel (alone and in combination) have been the most studied and have the most favorable risk-benefit profiles of drugs currently available. Prasugrel was recently approved for patients with acute coronary syndrome undergoing percutaneous interventions...

Bicuspid aortic valve (BAV) disease is the most common congenital cardiac defect. While the BAV can be found in isolation, it is often associated with other congenital cardiac lesions. The most frequent associated finding is dilation of the proximal ascending aorta secondary to abnormalities of the aortic media. Changes in the aortic media are present independent of whether the valve is functionally normal, stenotic, or incompetent. Although symptoms often manifest in adulthood, there is a wide spectrum of presentations ranging from severe disease detected in utero to asymptomatic disease in old age...
