COVID-19 myocarditis illusions: A new cardiac MRI study raises questions about the diagnosis
BY ANISH KOKA One of the hallmarks of the last two years has been the distance that frequently exists between published research and reality. I’m a cardiologist, and the first disconnect that became glaringly obvious very quickly was the impact COVID was having on the heart. As I walked through COVID rooms in the Spring of 2020 trying to hold my breath, I waited for a COVID cardiac tsunami. After all social media had been full of videos from Wuhan and Iran of people suddenly dropping in the streets. My hyperventilating colleagues made me hyperventilate. Could it be that Sars-COV2 had some predilection for heart...

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...

One family ’s disastrous experience with a growth-driven long-term care company
by “E-PATIENT” DAVE DEBRONKART Continuing THCB’s occasional series on actual experiences with the health care system. This is the first in a short series about a patient and family experience from one of America’s leading ePatients. I’ve been blogging recently about what happens in American healthcare when predatory investor-driven companies start moving into care industries because the money’s good and enforcement is lax. The first two posts were about recent articles in The New Yorker on companies that are more interested in sales and growth than caring. I now have permission ...

A teenager with chest pain, a troponin below the limit of detection, and " benign early repolarization "
Sent by anonymous, written by Pendell MeyersA male in his teens presented with complaints of chest discomfort and dyspnea beginning while exercising but without obvious injury. He immediately stopped exercising and symptoms started to improve. Later that evening he felt recurrent central chest discomfort, shortness of breath, and vomited. Symptoms have been constant since this second episode, and are still present on arrival, which seems to have been less than 1 to 2 hours from onset of symptoms. No similar symptoms in the past. No prior exertional complaints of chest pain, dizziness, lightheadedness, or undue shortness of...

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 paroxysmal nocturnal dyspnea?
In paroxysmal nocturnal dyspnea, patient wakes up with breathlessness and sits up or even stands. It is relieved over a few minutes. Paroxysmal nocturnal dyspnea is different from orthopnea which occurs soon after assuming the supine position and is relieved by sitting up. Orthopnea has no relation to sleep. Onset of paroxysmal nocturnal dyspnea is delayed after onset of sleep as it takes some time for the peripheral edema fluid to get absorbed and translocate to the lungs. PND usually occurs 2 – 4 hours after onset of sleep. Sympathetic withdrawal during sleep is also a proposed mechanism. Paroxysmal nocturnal dyspnea ...

Anemia in cardiac failure : Needs little more attention
HF is the inability (or reduced ability) to supply oxygen and other nutrients to fulfill the body’s demands. In the process, the heart either fights or flights, and results in symptoms due to hemodynamic alterations, or adversities of neuro-hormonal activation. Now, what is Anemia? Anemia is a condition with reduced or dysfunctional RBCs. that directly interferes with oxygen delivery to tissues. It is not at all a coincidence, the core functions of the heart and blood are strikingly similar and intertwined. While the heart is the powerhouse of the circulatory system, without good-quality blood, the greatness of th...

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 ascites precox?
The early occurrence of ascites in chronic constrictive pericarditis even before the appearance of generalised edema has been called ‘ascites precox’. Though ascites can occur in any severe long standing heart failure, it is most likely to occur in constrictive pericarditis and severe tricuspid valve disease.

Why is angina not a typical symptom of left ventricular aneurysm?
Angina pectoris indicates viable but ischemic myocardium. In ventricular aneurysm, it is usually a non-viable scarred area of myocardium, due to poorly collateralized chronically occluded coronary artery. The border zone of the aneurysm is vulnerable to form re-entrant circuits which can trigger ventricular tachycardia. As the aneurysmal segment bulges out in systole instead of contracting, the systolic effort of the left ventricle is wasted. Part of the effort of the remaining left ventricular muscle is wasted in moving blood in and out of the aneurysm pouch. This leads to heart failure. Mural thrombi can form in th...

What are the mechanical complications of acute myocardial infarction?
Typical mechanical complications of acute myocardial infarction are rupture of papillary muscle, rupture of interventricular septum and rupture of left ventricular free wall. Mechanical complications are more life threatening and seldom respond to medical management. They need early high risk surgery. Rupture of papillary muscle causes severe acute mitral regurgitation and pulmonary edema. Rupture of interventricular septum produces an acquired ventricular septal defect and leads to severe heart failure. Rupture of ventricular free wall causes hemopericardium and cardiac tamponade.
