COVID19 and Finding Effective Medical Therapies
This post introduces a column I wrote over at TheHeart.org | Medscape Cardiology — The good news is that most people infected with coronavirus don’t need a hospital or doctor. But some do. Some get very ill. The maddening thing is that doctors don’t have an effective treatment for the virus. There are no cures. The Worldmeter today shows nearly 5 million infections and more than 300,000 deaths. And no effective therapy. Excluding a possibly modest effect of Remdesivir, our care is supportive, which is medical jargon for giving simple things like oxygen, acetaminophen, IV fluids and letting ...

The 7 Must-Haves For The Doctor Of the 21st Century
While Doctor Who is embracing change, casting two female leads in a row as the titular character following the series’ tradition of having male leads, real life doctors should take some cues from the fictional doctor when it comes to change. For ages, physicians have been relying on traditional methods when it comes to consulting patients and follow a rote template akin to the following: patients see the doctor who auscultates them with manual techniques, without forgetting the stethoscope, and will prescribe them some medication or lifestyle change. In specific cases, they will recommend a more detailed diagnostic metho...

Burned out on Burnout?
Conclusion Learning how to pay attention to our attention (meta-attention) can be transformative. Using principles from cognitive science, we can create a comprehensive approach (attention capital theory in medicine) to reclaim the meaning and joy that has been depleted from our profession. Increasing the difficulty of our work to match our skill level, delegating low-level tasks to help us focus on critical steps in our physician zone, creating rules to eliminate distractions, and noticing both the wonder and suffering around us may be more important than resilience training or wellness modules. Although well-intention...

Cardiology MCQ – Coronary vasomotor function – Answer
Cardiology MCQ – Coronary vasomotor function – Answer Most validated and accurate noninvasive test for the quantitative assessment of coronary vasomotor function: Correct answer: 1. Positron emission tomography PET uses rest and vasodilator stress myocardial perfusion study after injection of blood flow radiotracers like 82Rubidium or 13N-ammonia. Image post processing yields regional and global myocardial blood flow in ml/min/g of myocardium. Coronary flow reserve is calculated as the ratio of stress to rest myocardial blood flow [1]. Assessing coronary flow reserve is important in patients with coronary micr...
