A big data COVID train wreck
BY ANISH KOKA If there was any doubt the academic research enterprise is completely broken, we have an absolute train wreck of a study in one of the many specialty journals of the Journal of the American Medical Association — JAMA Health. I had no idea the journal even existed until today, but I now know to approach the words printed in this journal to the words printed in supermarket tabloids. You should too! The paper that was brought to my attention is one that purports to examine the deleterious health effects of Long COVID. A sizable group of intellectuals who are still socially distancing and wearing n95s ...

The “open data” movement runs aground on FOURIER
BY ANISH KOKA Reanalysis of a trial used to approve a commonly used injectable cholesterol-lowering drug confirms the original analysis by accident. The open-data movement seeks to liberate the massive amount of data generated in running clinical trials from the grasp of the academic medical-pharmaceutical industrial complex that mostly runs the most important trials responsible for bringing novel therapeutics to market. There are only a few elite academic trialist groups capable of running large trials and there’s ample reason to be suspicious about the nexus that has developed between academia and the pharmace...

Predisposition to statin adverse effects
Some situations likely to predispose to statin adverse effects are impaired renal or hepatic function, history of previous statin intolerance or muscle disorders and unexplained elevation of SGPT. In addition to these, age above 75 years, Asian ancestry and previous hemorrhagic stroke are potential conditions to considered while considering high intensity statin therapy with regard to predisposition for adverse effects. Concomitant usage of drugs likely to affect statin metabolism should also be considered.

What is the best treatment option for prosthetic valve thrombosis presenting with stroke?
In patients having prosthetic valve thrombosis presenting with stroke, surgery is the first option as thrombolysis is contraindicated. Surgical treatment has a combined risk of death or stroke of 9%. For prosthetic valve thrombosis without stroke:  If the thrombus in the prosthetic valve is less than 5 mm in size, only intravenous heparin is recommended. For larger thrombi there are two options: thrombolysis versus surgical treatment. Thrombolysis has an initial success rate of 70 -80%, but there is a 5 -22% risk of embolism, and 5 -12% risk of disabling stroke. Thrombolysis is the preferred treatment ...

What is secondary AF?
Secondary AF has been defined as self limited atrial fibrillation caused by a reversible etiology. Conditions which cause secondary AF are myocardial infarction, myocarditis, pericarditis, acute pulmonary disease, hyperthyroidism, ethanol intoxication, sepsis and postoperative state. It is well known that postoperative AF can increase the morbidity and ICU/hospital stay after cardiac and non cardiac surgery. Reference Quon MJ, Behlouli H, Pilote L. Anticoagulant Use and Risk of Ischemic Stroke and Bleeding in Patients With Secondary Atrial Fibrillation Associated With Acute Coronary Syndromes, Acute Pulmonary Disease, or...

What is the commonest sustained arrhythmia in HCM?
Commonest sustained arrhythmia in hypertrophic cardiomyopathy is atrial fibrillation. Atrial fibrillation (AF) can occur in about 1/5th of cases of hypertrophic cardiomyopathy (HCM). Factors predisposing to AF in HCM are left atrial pressure and size due to left ventricular diastolic dysfunction, left ventricular outflow tract obstruction and mitral regurgitation. About one fourth of them may develop embolic episodes and stroke. It has been suggested that those with left atrial diameter of 45 mm or more should undergo 48 hour Holter once or twice a year to look for AF. Anticoagulation is recommended in those with AF ...

What is Modified Rankin Score (mRS)?
In the original Rankin score proposed in 1957, there were 5 grades of stroke severity ranging from “no significant disability” to “severe disability’ [1]. Modified Rankin Score (mRS) has been used to quantify disability after recovery from a cardiac arrest [2]. The score ranges from for 0 with no symptoms to 6 which would mean mortality. In between there is 1 with no significant disability and 2 with slight disability. Moderate disability requiring some help is 3 and 4 is moderately severe disability in which the person is not able to walk or attend to bodily needs without help. Modified Rankin Score 5 indicat...

What do you think of this " Ventricular Bigeminy " ?
Written by Bobby Nicholson MD, with edits by MeyersA woman in her 50s with past medical history of heart failure, prior stroke, atrial fibrillation on Eliquis, lung cancer in remission, and CKD, presented to the emergency department for evaluation of cough and shortness of breath. EKG was obtained in triage and read as ventricular bigeminy. What do you think?On my first read of the EKG, I agreed with the initial interpretation. Pendell Meyers then recommended that I take a second look at the morphology of the QRS complexes. I think it was easiest for me to see in the rhythm strip, but there are clearly P waves in front of ...

What is the most common cause of acquired heart disease in children in developed countries?
Kawasaki disease is the most common cause of acquired heart disease in children in developed countries. In developing countries it will be rheumatic heart disease. Timely treatment of Kawasaki disease with intravenous immunoglobulin can reduce the incidence of coronary aneurysms from 25% to around 4%. Children with coronary aneurysms due to Kawasaki disease needs lifelong cardiology follow up. The prognosis depends on the initial and current level of coronary involvement. Some children may develop coronary obstruction and thrombosis leading to myocardial infarction. Revascularization procedures may be needed in some of th...

High Blood Pressure and Erectile Dysfunction
Research confirms that high blood pressure and ED are closely linked. But did you know the majority of cases of ED are caused by hypertension? Keep reading to find out more. Experts suggest that “hypertension is sometimes a standalone condition and sometimes it’s associated with other conditions, which also impact erectile dysfunction.” According to the European Society of Cardiology, this likelihood is almost double in men with uncontrolled high blood pressure. Long-term exposure to hypertension and elevated blood pressure damages the arterial wall. This leads to atherosclerosis and the narrowing of art...

17 Ways to Become an Awesome EMT
Want to become more awesome in 2022? Here are 17 places you can start: 1) Start Checking Out Your Rig Each Morning Most organizations have a policy in place that states that oncoming EMS crews should complete a thorough checkout process. The reality is that very few of us check out our rig at the beginning of each shift with the proper attention that the task deserves. We know we should, but we get caught up. The signs of an incomplete rig checker are subtle but recognizable. If you open your cabinet or kit on a call and note (for the first time) that you are low or absent a needed supply, you’re not checking o...

In which condition is a hyperkinetic pulse associated with a normal pulse volume?
Hyperkinetic pulse usually has a high pulse volume but in hypertrophic obstructive cardiomyopathy, is it associated with a normal pulse volume. A hyperkinetic pulse in HOCM is due to rapid initial rate of development of left ventricular pressure. Volume is not high because left ventricular outflow obstruction sets in soon. A hyperkinetic pulse with normal pulse volume may also be noted in mitral regurgitation. Here again the dilated left ventricle empties rapidly, but volume is not high because part of the blood goes back into the left atrium and not the aorta. In all other conditions with hyperkinetic puls...
