Enhancing Cardiovascular Disease Risk Prediction: Comparing Coronary Artery Calcium and Polygenic Risk Scores A Northwestern University study revealed that both coronary artery calcium and polygenic risk scores significantly influence 10-year risk prediction for coronary heart disease. However, coronary artery calcium score demonstrated superior predictive power, reinforcing the integration of these novel tools in risk prediction models. “What this study says is that in white participants enrolled in 2 observational studies, identifying coronary calcium predicted future cardiac events better than our currently available polygenic risk scores.” Dr. Karol E. Watson, PhD, professor of medicine and cardiology at the David Geffen School of Medicine at the University of California Los Angeles

Evaluating the Timing of DOAC Initiation Post-Stroke: Key Findings Here are the key findings from a recent multi-country, open-label research that explores the best time to start direct oral anticoagulants (DOACs) in atrial fibrillation patients after a stroke.

Dive into how the FDA-approved Farxiga is changing the heart failure treatment landscape. Colleagues, let’s dive into a remarkable milestone. Farxiga, known as dapagliflozin, now has FDA approval. This is groundbreaking for heart failure treatment. It applies to all patients, regardless of their left ventricular ejection fraction (LVEF) status. The approval didn’t happen overnight. Let’s talk about the DELIVER trial, a vital part of the process. It involved over 6,000 patients, all over 40. Each had heart failure, LVEF above 40%, and may or may not have had type 2 diabetes. They took either dapagliflozin or a placebo daily, plus their usual therapy. The trial had a clear goal: time to the first composite event. This included CV death, heart failure hospitalization, or an urgent heart failure visit. The goal applied to everyone, including patients with LVEF less than 60%. Fast forward about 2.3 years, the results were significant. Dapagliflozin cut the composite outcome by 18% versus the placebo. Both worsening heart failure and CV death rates dropped in the dapagliflozin group. The best part? These findings were consistent, even in patients with lower LVEF or diabetes. Expanding the picture, let’s consider two trials together: DELIVER and DAPA-HF. Over 22 […]

Navigate the complex world of diagnosing Chiari malformation in this insightful review of a clinical case. To understand Chiari malformation, let’s explore a clinical case. A mid-30s patient with a migraine history came to the ED with a sudden posterior headache. Accompanied by transient total body numbness, loss of coordination, and an inability to swallow with drooling, these symptoms started abruptly after violent sneezing. Although neurological symptoms faded after 20 seconds, the headache persisted. Regarding vital signs and physical examination, everything was normal. The patient had a head CT ordered. Interpreting the clinical picture and CT images with care is crucial in these cases. Even though a sudden onset headache could signify a ruptured berry aneurysm, no blood was detected on the CT cuts, minimizing that concern. Remember, an LP is seldom recommended if the CT is performed within 6 hours and hemoglobin exceeds 10 g/dL. However, the clinical presentation in this case, characterized by headache and drooling, didn’t match a typical migraine. Be mindful that many patients might loosely use the term “migraine” for any severe headache. The CT cut revealed a brainstem compressed by the cerebellum, indicative of a Chiari malformation type 1. Chiari malformation, characterized by an […]

This deep-dive into acromioclavicular joint injuries unpacks everything a physician needs to know about these prevalent injuries. Acromioclavicular joint (ACJ) injuries, mostly traumatic, can occur across all ages but are more frequent in males aged 20-40, often related to contact sports. Patients usually present with vague shoulder pain and swelling, but visible deformity is rare. Two mechanisms contribute to ACJ injuries: direct, resulting from a direct blow or fall onto the shoulder, and indirect, arising from a fall onto an outstretched hand or elbow. Imaging is crucial for diagnosis. The Rockwood system, among others, categorizes these injuries into six types. Plain radiographs, including an axillary view, generally suffice for accurate grading. However, in certain scenarios, CT or MRI might be necessary. In case of an injury suspicion with initial normal radiographs or contemplating surgical intervention on a type III injury, additional weight-bearing stress views can be beneficial. Indications of ACJ injury on a plain radiograph may include soft tissue swelling, acromioclavicular joint widening, increased coracoclavicular distance, and superior displacement of the distal clavicle. The treatment choice hinges largely on the patient’s age, lifestyle, and injury type. Conservative management typically applies to types I and II injuries, surgical treatment to types […]

In a cluster-randomized trial conducted across multiple countries, a multicomponent clinical intervention was evaluated for the management of postpartum hemorrhage in patients undergoing vaginal delivery. The intervention involved the use of a calibrated blood-collection drape for early detection of postpartum hemorrhage and a treatment bundle consisting of various interventions. The study found that the intervention group had a lower risk of severe postpartum hemorrhage, laparotomy for bleeding, or death from bleeding compared to the usual-care group. The intervention group also had higher rates of postpartum hemorrhage detection and adherence to the treatment bundle.
