AF, Ablation, Stents and Five Nuances
Joan has left an excellent comment on my recent 2019 AF ablation update. She brings up many important issues. Let’s dissect it. Q: Joan asks if it is common to see patients who think they are cured after AF ablation but are still in AF?  A: The scenario I described in my previous post is not common, but it is not rare. Since AF ablation entails much instrumentation and many burns, it can affect how the heart feels things. The heart has its own nervous system; yes, the heart feels. Also, the bigger the procedure, the bigger the placebo effect.  Q: If ablation doesn’t work, then I sure know a lot of peo...

Top Smart Algorithms In Healthcare
As artificial intelligence tools have been invading more or less every area of healthcare, we made a list to keep track of the top smart algorithms aiming for better diagnostics, more sophisticated patient care or further sighted predictions of diseases. Does A.I. beat doctors? Only if you lived under a rock for the last couple of years, could you not have heard about artificial intelligence. Some might have even come across the spread and potential of A.I. in healthcare. Not only smart algorithms themselves but also the hype around A.I. has grown immensely, thus every time a new study about deep learning or machine...

Should Troponin be a Vital Sign? Perhaps, but only if Interpreted Using Pre-test Probability.
Conclusions When high sensitivity cardiac troponin testing is performed widely or without previous clinical assessment, elevated troponin concentrations are common and predominantly reflect myocardial injury rather than myocardial infarction. These observations highlight how selection of patients for cardiac troponin testing varies across healthcare settings and markedly influences the positive predictive value for a diagnosis of myocardial infarction.-----------------------------------------------------------Comment by KEN GRAUER, MD (2/5/2019):-----------------------------------------------------------Exce...

Evidence less cardiology : Is “ No-flow ” better than “ No-reflow ” in STEMI ?
Cath labs are propably the best place to practice preventive cardiology . . . Practice of medicine is primarily guided by Infinite Information , plenty of Intuition, little bit of Intelligence and unquantifiable amount of Ignorance.The science of coronary reperfusion is standing example for variable mix of the above.The term no reflow is a jargan used liberally in cath labs right from first year fellow to super consultant without knowing what exactly they mean by it. What really is No-reflow then ? The academic definition :According to Kloner no-reflow is defined as suboptimal myocardial reperfusion through a part of coron...

IABP for Cardiogenic Shock – Cardiology MCQ – Answer
IABP for Cardiogenic Shock – Cardiology MCQ – Answer Routine placement of Intra Aortic Balloon Pump (IABP) for cardiogenic shock is a Class —  recommendation as per the 2017 European Society of Cardiology Guidelines for ST-segment elevation myocardial infarction [1,2] – Correct answer: 4. Class III IABP-SHOCK II trial and its 6 year follow up data [2] did not show any mortality benefit for those who were randomly assigned to receive IABP support. There were no differences in the frequency of recurrent myocardial infarction, repeat revascularization, stroke or rehospitalization for a cardiovascular...

Fight Aging! Newsletter, January 14th 2019
In conclusion, reduction of LDL-C to less than 50 mg/dl seems safe and provides greater CV benefits compared with higher levels. Data for achieved LDL-C lower than 20-25 mg/dl is limited, although findings from the above mentioned studies are encouraging. However, further evaluation is needed for future studies and post-hoc analyses. Wary of the Beautiful Fairy Tale of Near Term Rejuvenation https://www.fightaging.org/archives/2019/01/wary-of-the-beautiful-fairy-tale-of-near-term-rejuvenation/ One might compare this interview with researcher Leonid Peshkin to last year's discussion with Vadim Gladyshev. ...

People who live in neighborhoods with green spaces have less stress, healthier blood vessels and lower risk of heart attack and stroke
People who live in neighborhoods with more green spaces may have less stress, healthier blood vessels and a lower risk of heart attacks and strokes.Residential greenness is associated with lower levels of sympathetic activation, reduced oxidative stress, and higher angiogenic capacity. This is independent of age, sex, race, smoking status, neighborhood deprivation, statin use, and roadway exposure.For this study (see the link below), researchers tested for a variety of biomarkers of stress and heart disease risk in blood and urine samples from 408 patients at a cardiology clinic in Louisville, Kentucky, USA.Residents of th...

The Interventionalist Refuses Angiography, and even to speak to the Emergency Physician
A recent residency graduate, let ' s call her " The Graduate " or " TG, " texted me these ECGs from somewhere far away across the country, in real time, in the hopes of being able to persuade the interventionalist to take the patient to the cath lab.CaseAn otherwise healthy middle-aged patient presented with chest pain of uncertain duration.Here is the initial ED ECG (I apologize for the poor quality of these images -- they were mobile phone photos of computer screens, texted to me -- but they are good enough!):What do you see?There was a second ECG after the patient had symptom resolution:What do you see?This is what TG a...

One of the Great Books of Emergency Medicine Just Published: Extraordinary Cases in Emergency Medicine
This article that established thrombolytic therapy for STEMI as the domain of emergency medicine, not of cardiology.  It made me realize I needed to recognize coronary occlusion on the ECG and differentiate it from PseudoSTEMI patterns.  We emergency physicians could only rely on ourselves to make the right and timely diagnosis because waiting for a cardiologist was to wait too long.Doug and Hennepin (Ernie Ruiz, Joe Clinton, Dave Plummer, and more) taught me long ago that we Emergency Physicians must be the deciders.And that is just one of his countless contributions to EM over a 37 year career.Doug has collecte...

The VERDICT Trial
This study is unable to comment on whether patients with STEMI(-) Occlusion MI have benefit from emergent cath, because that is not the population studied and this subgroup is not commented on.This study is just the most recent in a long long line of similar literature. Context is everything for understanding this study.
