A 70 something male presented in severe respiratory distress. The patient had altered mental status and so he was prepared for intubation. Before intubation, he became hypotensive. On the monitor patient had wide-complex tachycardia. The following 12-lead was obtained: What do you think? Differential is ventricular tachycardia versus supraventricular tachycardia with aberrancy versus sinus tachycardia with a aberrancy.
What role do omega-6 fatty acids play in cardiovascular disease and diabetes? Scientists from Mannheim, together with researchers from Heidelberg, Frankfurt, and Hangzhou in China, have investigated the breakdown of omega-6 fatty acids and gained new insights into how their oxidation products influence the metabolism.
Ghrelin exerts key effects on islet hormone secretion to regulate blood glucose levels. Here, we sought to determine whether ghrelin’s effects on islets extend to the alteration of islet size and β cell mass. We demonstrate that reducing ghrelin — by ghrelin gene knockout (GKO), conditional ghrelin cell ablation, or high-fat diet (HFD) feeding — was associated with increased mean islet size (up to 62%), percentage of large islets (up to 854%), and β cell cross-sectional area (up to 51%).
Objectives To determine the clinical profile, according to the history of hypertension, the risk of developing hypertension, current antihypertensive treatment and BP control rates in patients with hypertension from the IBERICAN cohort. Methods IBERICAN is an ongoing prospective cohort study, whose primary objective is to determine the frequency, incidence, and distribution of CVRF in the adult Spanish population seen in primary care settings.
The ECG in Figure-1 — was obtained from a patient with palpitations. The patient was hemodynamically stable in association with this rhythm. QUESTIONS: What is the rhythm in Figure-1 ? — How certain are you of your answer? — Why is QRS morphology changing ? Figure-1: The initial ECG in today's case. My Interpretation of the ECG in Figure-1: Since the patient is hemodynamically stable — there is time for systematic assessment of the rhythm.
Research Highlights: A study of married or partnered, middle-aged and older heterosexual couples in the U.S., England, China and India found that in 20% to 47% of the couples, both spouses/partners had high blood pressure. The prevalence of both.
HPI: A 50-year-old man decides to get “his life in order” for the new year. He quits smoking, decides to eat healthier and exercise more, and to be more compliant with his blood pressure medications. A week into the new year he wakes up feeling weak and achy with nausea and vomiting. He is lightheaded when sitting or standing and has trouble getting out of bed.
Researchers have succeeded in restoring lost brain function in mouse models of stroke using small molecules that in the future could potentially be developed into a stroke recovery therapy.
Analysis of the NUDGE-FLU study reveals electronic nudges designed to boost influenza vaccination were more effective in older adults without diabetes, highlighting the need for tailored approaches in diabetes populations.

In this ECG Cases blog Dr. Jesse MacLaren guides us through 10 cases of patients who present with generalized weakness or acute neurologic symptoms and discusses how to look for ECG signs of dysrhythmias, electrolyte emergencies, acute coronary occlusion, and demand ischemia in patients with generalized weakness and in patients with neurologic symptoms, to consider predisposing factors like LVH; seizure-like activity from cardiac syncope; TIA/CVA embolic sources like atrial fibrillation or LV th
Case submitted by anonymous. Written by Smith. Ken's piece at the bottom is excellent. A 50-something presented with s udden onset palpitations 8 hrs prior while sitting at desk at work. He had concurrent sharp substernal chest pain that resolved, but palpitations continued. Over past 3 months, he has had similar intermittent episodes of sharp chest pain while running, but none at rest.
A new artificial intelligence (AI) model designed by Scripps Research scientists could help clinicians better screen patients for atrial fibrillation (or AFib)—an irregular, fast heartbeat that is associated with stroke and heart failure. The model picks up on tiny variations in a person's normal heartbeat that signify AFib risk, which standard screening tests cannot detect.
A paucity of chemotherapeutic options for metastatic brain cancer limits patient survival and portends poor clinical outcomes. Using a CNS small-molecule inhibitor library of 320 agents known to be blood-brain barrier permeable and approved by the FDA, we interrogated breast cancer brain metastasis vulnerabilities to identify an effective agent. Metixene, an antiparkinsonian drug, was identified as a top therapeutic agent that was capable of decreasing cellular viability and inducing cell death
The ECG in Figure-1 — was obtained from a middle-aged man with palpitations and shortness of breath. He was hemodynamically stable at the time this tracing was recorded. How would YOU interpret the ECG in Figure-1 ? Is there evidence of a recent or ongoing acute MI? What might you do first? Figure-1: The initial ECG in today's case. ( To improve visualization — I've digitized the original ECG using PMcardio ).

If a wide complex tachycardia occurs, the probability is very high that it is a ventricular tachycardia (approx. 80%, in patients with a previous myocardial infarction (.) approx. 90%). Here we see a broad complex tachycardia that looks like an RBBB + LAFB, which is regular. In this constellation, 3 causes must be considered: 1. fascicular tachycardia from the left posterior fascicle of the left tawara fascicle (QRS width usually only around 130 ms, but sometimes significantly longer). 2.

Acute spinal cord injury (SCI) patients lose body weight and muscle mass, despite being on a high-calorie diet while in the intensive care unit. Their muscle wasting is substantial and extends beyond what can explained by inactivity or denervation (loss of nerve supply) alone. Research sheds new light and decodes early muscle loss after SCI to provide an unprecedent first understanding that muscle wasting is rapid and severe; a systemic phenomenon and glucocorticoid dependent.
Researchers have discovered that a certain kind of protein similar to hemoglobin, called cytoglobin, plays an important role in the development of the heart. Specifically, it affects the correct left-right pattern of the heart and other asymmetric organs. The findings could eventually lead to the development of new therapeutic interventions to alter the processes that lead to these defects.
