Ischemic cardiomyopathy: Why is it, still searching for a definition?
The term Ischemic cardiomyopathy(ICM) was originally coined by Dr. Burch from Tulane University, New Orleans, USA in 1970. For many decades there was skepticism regarding the existence of such entity. WHO classification over the years never included this term. ESC working group of 2008 (Elliott P, European Heart 29(2):270–276) decided not to include CAD as a cause for cardiomyopathy. Even the current MOGES system doesn’t invoke CAD as a cause for cardiomyopathy. But, I am sure, most of practicing cardiologists would agree, there is a need for such an entity.
Why there is much reluctance to diagnose Ische...

How does acute left main occlusion present on the ECG?
Post by Smith and MeyersSam Ghali (https://twitter.com/EM_RESUS) just asked me (Smith):" Steve, do left main coronary artery *occlusions* (actual ones with transmural ischemia) have ST Depression or ST Elevation in aVR? "Smith and Meyers answer:First, LM occlusion is uncommon in the ED because most of these die before they can get a 12-lead recorded.But if they do present:The very common presentation of diffuse STD with reciprocal STE in aVR is NOT left main occlusion, though it might be due to subtotal LM ACS, but is much more often due to non-ACS conditions, especially demand ischemia. In these ...

What happens when you don ' t recognize an OMI?
This was sent by an " avid reader. " The case was from his hospital, which does not have a cath lab. He was very frustrated by the care the patient received from his partner, and the absence of an appropriate openness to learning by those in his department.CaseA 60-something male was sent in from a cardiologists ' office after presenting there with chest pain. The office ECG is unavailable.The pain had been intermittent for a few days, but worse on the day of admission.Here was the initial ECG:To me, and to him, this is an obvious acute LAD occlusion.There are hyperacute T-waves, especially in V2, plus ot...

Over-the-counter cold and flu medicines can affect your heart
As the cold and flu season continues this year, it is important to be aware that many of the most commonly used over-the-counter (OTC) remedies for congestion, aches, pains, and low-grade fevers contain medicines that can have harmful effects on the cardiovascular system. Chief among these medications are nonsteroidal anti-inflammatory drugs (NSAIDs) and decongestants.
NSAIDs and your heart
Certain NSAIDs are associated with a small increase in the relative risk for developing a heart attack, stroke, heart failure, atrial fibrillation, increased blood pressure, and blood clots. NSAIDs relieve pain and inflammation by inhib...

IV Acetaminophen prevents post op delirium
Intravenous acetaminophen (paracetamol) when added to a sedative has been found to reduce the risk of postoperative delirium in patients after cardiac surgery [1]. Post operative delirium is common after surgery in elderly persons. It often increases the length of hospital stay and naturally the expenses and has adverse effects on final outcome.
The DEXACET Randomized Clinical Trial randomized 120 elderly patients undergoing coronary artery bypass surgery (CABG) or combine CABG/valve surgery. Four groups received either intravenous acetaminophen or placebo and sedative IV propofol vs dexmedetomidine. Primary outcome measu...

Left main coronary artery disease on ECG
Left main coronary artery disease on ECG
ST segment elevation in aVR and diffuse ST segment depression in inferior and anterolateral leads is considered a feature of significant left main coronary artery disease. The ECG shown above, there is ST segment elevation in aVR and V1 along with ST depression in inferior and lateral leads. ST elevation in aVR more than that in V1 is also suggestive of left main disease. In a study comparing acute obstruction of left main, left anterior descending (LAD) and right coronary (RCA) occlusions, aVR ST elevation of more than 0.05 mV was noted in 88% of left main (LMCA) obstruction, 43% ...

Coronary artery and veins are married life long . . . with a purpose !
Cardiologist are always worried about the supply side of coronary blood flow. It’s fair enough, we can condone our brain for this one way thinking , afterall arterial supply remain the life-line for the heart. Some of us could (should) realise the importance of these humble coronary veins which are anatomically and physiologically tied together.Its existence is as unique as their arterial counterpart.Coronary blood flow of about 250 ml traverses both the arms every minute.Imagine the scenario if the veins refuse to clear the blood from previous cardiac cycle . . . total hemodynamic chaos right ? Luckily such s...

Post by Smith, with short article by Angie Lobo (https://twitter.com/ALoboMD), a third year intermal medicine resident at Abbott Northwestern Hospital CaseA 30-something woman with no past history, who is very fit and athletic, presented with 1.5 hours of substernal chest pressure. It was non-radiating and without other associated symptoms except for nausea. She had zero CAD risk factors.Here was her ECG at time zero:What do you think?There is ST elevation in V2 with large fat T-wave. There is ST depression in II, III, and aVF, and V3 to V6.I saw this before any other information and k...

Life as a doctor is selfless and selfish at the same time
It was 5:45 in the morning on a Monday after a full weekend of call. Thoroughly exhausted, I shuffled into the elevator and was met by the stench of stale clothing mixed with cigarette smoke. A painfully thin teenager exited, looking lost. I allowed him to wander out, grateful to be spared his odor. I was apathetic, overtaken by a weariness I vowed as a medical student never to have.
Morning rounds passed without incident. All our CABG patients were more or less stable. I collected each patient’s overnight events, vital signs, laboratory values, daily chest X-ray, EKG, fluid balance and wound status. With my attending’...

You have two hours to save this patient ' s life
Written by Pendell Meyers, edits by Steve SmithA female in her 60s with history of CAD s/p PCI and CABG, alcohol abuse, and recurrent pancreatitis presented at 14:55 complaining of sudden onset epigastric pain. Initial vital signs were heart rate 44 bpm, respiratory rate 16, BP 143/67, SpO2 96% on room air. On initial exam she was in mild distress and complaining of severe nausea.Here is her initial ECG:What do you think?There is decreased ECG quality due to baseline movement. Despite this, there are clearly hyperacute T-waves in lead III with reciprocal negative hyperacute T-waves in aVL (and lead I) with likely a small a...
