Episode 15 Part 1: Acute Coronary Syndromes Risk Stratification
In Part 1 of this Episode on Acute Coronary Syndromes Risk Stratification Dr. Eric Letovksy, Dr. Mark Mensour and Dr. Neil Fam discuss common pearls and pitfalls in assessing the patient who presents to the ED with chest pain. They review atypical presentations to look out for, what the literature says about the value of traditional and non-traditional cardiac risk factors, the diagnostic utility of recent cardiac testing, and which patients in the ED should have a cardiac work-up. Finally, in the ED work up of Acute Coronary Syndromes Risk Stratification, they highlight some valuable key points in ECG interpretation and how best to use and interpret cardiac biomarkers like troponin. Drs. Letovksy, Mensour & Fam address questions like: How useful are the traditional cardiac risk factors in predicting ACS in the ED? How does a negative recent treadmill stress test, nuclear stress test or angiogram effect the pre-test probability of ACS in the ED? What does recent evidence tell us about the assumption that patients presenting with chest pain and a presumed new LBBB will rule in for MI and require re-perfusion therapy? How can we diagnose MI in the patient with a ventricular pacemaker? What is the difference between Troponin I and Troponin T from a practical clinical perspective? Is one Troponin ever good enough to rule out MI in the patient with a normal ECG? Should we be using a 2hr delta troponin protocol? How will the new ultra-sensitive Troponins change our practice? and many more.....
Best Case Ever 4 Acute Coronary Syndrome From Venous Source
In anticipation of Episode 15, 'Acute Coronary Syndromes' with Dr. Eric Letovsky, Dr. Mark Mensour and Dr. Neil Fam, we present here, Dr. Helman's 'Best Case Ever' of an ACS patient. In Episode 15: 'Acute Coronary Syndromes', Drs. Fam, Mensour , Letovsky and Helman discuss questions like: How does a recent negative stress test or angiogram effect the pre-test probability of ACS in the ED? What does recent evidence tell us about the assumption that patients presenting with chest pain and a presumed new LBBB will rule in for MI and require reperfusion therapy?

Episode 12 Part 2: ACLS Guidelines – Atropine, Adenosine & Therapeutic Hypothermia
In Part 2 of this episode on ACLS Guidelines - Atropine, Adenosine & Therapeutic Hypothermia, Dr. Steven Brooks and Dr. Michael Feldman discuss the removal of Atropine from the PEA/Asystole algorithm, the indications and dangers of Adenosine in wide-complex tachycardias, pressors as a bridge to transvenous pacing in unstable bradycardias, and the key elements of post cardiac arrest care including therapeutic hypothermia and PCI. They answer questions such as: In which arrhythmias can Amiodarone cause more harm than good? Is there any role for transcutaneous pacing for asystole? When should Bicarb be given in the arrest situation? In what situations is Atropine contra-indicated or the dosage need to be adjusted? How has the widespread use of therapeutic hypothermia currently effected our ability to prognosticate post-arrest patients? What are the indications for PCI and thrombolysis in the cardiac arrest patient? Should we be using therapeutic hypothermia in the non-Vfib arrest patient? What is the best method for achieving the target temperature for the patient undergoing therapeutic hypothermia? and many more......
Episode 12 Part 1: ACLS Guidelines – What’s New & Controversial
In Part 1 of this episode on the latest ACLS Guidelines, Dr. Steven Brooks and Dr. Michael Feldman review and debate what's new and what's controversial in the the 2010 American Heart Association Guidelines for Cardiopulmonary Resuscitation and Emergency Cardiovascular Care. Within the frameworks of Cardiocerebral Rescusitation and the 3 phase model of rescucitation (electrical, circulatory and metabolic), they discuss the importance of high quality CPR, the de-emphasis on early ventilation and the utility of continuous quantitative waveform capnography. Dr. Brooks and Dr. Feldman answer questions such as: of all the therapeutic manoeuvres we do for the cardiac arrest patient, which ones have been shown to improve survival to hospital discharge? What is the evidence for chest compression machines? What is the utility of bedside ultrasound in the cardiac arrest patient? Why is cardiac arrest survival to discharge in Seattle the best in the world? Should we be performing 'hands-on defibrillation'? and many more.....
Episode 6: Transient Ischemic Attack
Transient Ischemic Attack (TIA) can be difficult to diagnose. It's unclear who to work up. It's challenging if the patient is already taking blood thinners. Dr. Walter Himmel and Dr. Daniel Selchen discuss the key historical and physical examination maneuvers to determine whether patients with neurologic complaints have had a TIA or whether they have had a TIA mimic. They review the 3 best risk stratification rules including the ABCD2 Score to help us determine who needs to be admitted and who needs timely investigations to reduce vascular morbidity and mortality. The reasoning behind which patients require urgent carotid imaging, echocardiograms and advanced imaging such as CT Angiogram is explained, and the best medication choices are reviewed, as well as the indications for Clopidogrel, Aggrenox, Warfarin, Heparin and carotid endarterectomy in the managment of Transient Ischemic Attack. In the second part of the episode, a simple and practical approach to the patient with dizziness is presented, and a discussion on which patients with dizziness need urgent work-up and treatment for vertebrobasilar TIA.
Episode 4: Acute Congestive Heart Failure
Dr. Eric Letovsky and Dr. Brian Steinhart describe a practical way to approach patients with undifferentiated SOB and acute congestive heart failure, the utility of various symptoms and signs in the diagnosis of CHF, as well as the controversies surrounding the best use of BNP and Troponin in the ED. A discussion of the use of ultrasound for patients with SOB as well as the indications for formal Echo are reviewed. In the second part of the episode they discuss the management of acute congestive heart failure based on a practical EM model, as well as the difficulties surrounding disposition of patients with CHF.
