An athletic 30-something woman with acute substernal chest pressure
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...

Smart Stent Monitors Blood Flow, Detects Restenosis
Vascular stents are some of the most commonly implanted medical devices, keeping millions of arteries open to uninterrupted blood flow. Though they tend to work well at first, too many end up being re-stenosed by new deposits of plaque and scar tissu...

Shock index and modified shock index for prediction of myocardial damage and clinical outcome of STEMI
Shock index is the ratio of heart rate to systolic blood pressure which allows rapid bedside risk stratification [1]. Modified shock index is the ratio of heart rate to mean arterial pressure [2]. Reinstadler SJ et al [2] used these indices to predict the myocardial damage and clinical outcome of ST segment elevation myocardial infarction (STEMI). They found that STEMI patients with elevated shock index had more severe myocardial and microvascular damage and it was associated with major adverse cardiac events (MACE) at 1 year.
This multicenter study analyzed around eight hundred patients dicotomized to an admission shock ...

Left Bundle Branch Block, Severe Chest pain, Previous Normal Angio. What is going on?
A middle-aged woman with idiopathic cardiomyopathy and biventricular failure, with previous EF of 15%, presented withsudden onset severe substernal chest pain. She had LBBB with a wide QRS, and therefore was a candidate for biventricular pacer for cardiac resynchronization, but when they had inserted her pacemaker, they could not get the LV lead into place (technical difficulties). Therefore, she had a typical RV pacer.She had arecent near perfect angiogram, described below. Here is her initial ED ECG:1. Is it paced?2. What do you notice compared to the previous, below?3. Is there any...

Chest pain, Ventricular Paced Rhythm, and a Completely Normal Angiogram 3 Months Prior.
One of our graduates, Rochelle Zarzar, who is now an education fellow, sent me this from one of the hospitals she works at now:An elderly woman presented with chest pain. She had been nauseous the night before and did not feel well, then awoke 2 hours prior with chest pain.She had had a completely normal angiogram 3 months prior.Here is that angiogram report:The left main coronary artery is normal.Left anterior descending is a type 3 vessel and is normal.Left circumflex is nondominant and normal.The right coronary artery is dominant and normal.The nurses immediately recorded an ECG. This was 2 hours after the o...

Why routine thrombus aspiration is prohibited in STEMI ?
It was 1912 , Titanic had just sank off the Atlantic . When the world attention was elsewhere , An unassuming young Dr.Herrick J.B silently working in his Michigan lab inquisitively proposed thrombus occluding the coronary artery is the chief culprit in acute myocardial Infarction.It took seven more decades when Davis et all from Glasgow .UK. proved it by doing dramatic angiographic studies soon after STEMI in year 1979.
Now, even after 100 years , we, the confused cardiologists debate endlessly in glamorous global conclaves in exotic locales whether to aspirate these humble looking thrombus, threatening to...

ST-Elevation in aVR with diffuse ST-Depression: An ECG pattern that you must know and understand!
This case comes from Sam Ghali (@EM_RESUS). A 60-year-old man calls 911 after experiencing sudden onset chest pain, palpitations, and shortness of breath. Here are his vital signs:HR: 130-160, BP: 140/75, RR:22, Temp: 98.5 F, SaO2: 98%This is his 12-Lead ECG:He is in atrial fibrillation with a rapid ventricular response at a rate of around 140 bpm. There are several abberantly conducted beats. There is ST-Elevation in aVR of several millimeters and diffuse ST-Depression with the maximal depression vector towards Lead II in the limb leads and towards V5 in the precordial leads.ECG reading is all ab...

Cath lab tips : Post dilatation is an unique “ Art ” . . . can ’ t learn it from textbooks or workshops !
In the modern era of cardiology, PCI has become the single therapeutic modality that determines the survival of both cardiologists and possibly their patients! The procedure is all about launching a metal coil inside the coronary artery of a live beating heart.
Millions of diseased and (not much) diseased coronary arteries are serviced (either re/deconstructed ) world-wide on a day-to-day basis.The benefits of the modality is directly related to the wisdom of treating cardiologist and patient’s luck than the original severity of the disease. However, with greatly improved coronary metallurgy , well assist...

A reaction to ORBITA: Keep on stenting, judiciously
Physicians’ reactions to ORBITA — a blinded, randomized controlled trial (RCT) from Britain with a sham arm comparing percutaneous coronary intervention (PCI) to placebo in patients with stable angina — are as fascinating as the cardiac cycle. There were murmurs, kicks and pulsating jugulars. Though many claimed to be surprised and many unsurprised by the null results of the trial, the responses were predictably predictable. Some basked in playful schadenfreude, and some became defensive and bisferious.
No shame in sham
The coverage of the trial in the The New York Times was predictably jejune and hyperbolic. Predict...

Orbiting ORBITA
By ANISH KOKA, MD
I’m sitting amidst a number of cardiologists to go over the most recent trials presented at the interventional cardiology conference in Denver. The cardiology fellow presenting goes quickly through the hors de oeuvres until finally getting to the main course – ORBITA.
ORBITA sought to test the very foundations interventional cardiology was built on – the simple idea that opening a stenosed coronary artery was good for patients. The trial was a double blind randomized control trial of patients with tightly stenosed arteries who either had a stent placed or had a sham procedure. Before the resul...

Echocardiographic assessment of myocardial viability
Diastolic wall thickness will give an idea regarding the myocardial viability. Thin and hyperdense myocardium is likely to be scarred and non viable. Dobutamine stress echocardiography documents the contractile reserve of the myocardium and hence indicate viability. Myocardial perfusion is assessed by myocardial contrast echocardiography. Strain and strain rate imaging is done by tissue Doppler and speckle tracking. There are various methods of assessing diastolic dysfunction using Doppler and tissue Doppler echocardiography.
End diastolic wall thickness (EDWT)
End diastolic wall thickness (EDWT) is one of the simplest me...

Myocardial viability assessment
The term viable myocardium is applied to myocardium with a potentially reversible contractile dysfunction in patients with coronary artery disease. It can be divided into stunned myocardium and hibernating myocardium. Stunned myocardium has prolonged contractile dysfunction after a transient ischemic episode and coronary reperfusion. This automatically recovers over a period of time. Stunned myocardium is commonly noted after thrombolysis and primary percutaneous coronary intervention. Hibernating myocardium has reduced contractile function due to persistently impaired coronary blood flow. Hibernating myocardium regai...

DAPT score – Dual Antiplatelet Therapy Score
DAPT score (Dual Antiplatelet Therapy Score) was developed to dichotomize patients after percutaneous coronary intervention [PCI] into those who will benefit from prolonged DAPT (score 2 or more) and those who are more likely to be harmed by DAPT (score less than 2). A recent study evaluated DAPT with aspirin and clopidogrel given for 2 years vs 6 months in 1970 patients undergoing PCI [1]. Primary efficacy outcomes were death, myocardial infarction or cerebrovascular accident. Primary safety outcome was significant bleeding. In this retrospective study they concluded that prolonged DAPT resulted in harm in patients with l...
