Written by Jesse McLaren Four patients presented with chest pain. All initial ECGs were labeled ‘normal’ or ‘otherwise normal’ by the computer interpretation, and below are the ECGs with the final cardiology interpretation. If you were working in a busy emergency department, would you like to be interrupted to interpret these ECGs or can these patients safely wait to be seen because of the normal computer interpretation?

Objective We investigated the relationship between using a rotary compression device (RCD) with or without sterile gauze and adverse events in transradial access (TRA) for coronary intervention. Methods In this study involving 933 patients at Yueyang Hospital, we recorded TRA-related adverse events, such as bleeding, forearm hematoma, swollen palms, radial artery occlusion (RAO) and others.

The patient is a 20 something female. She is healthy with no known cardiac disease. She was admitted to the neurology department due to headache and vomiting. She was found to have a viral CNS infection. A few days into her hospital stay she developed chest discomfort and the following ECG was recorded. What do you think? Why such large T-waves? Are these hyperacute T-waves?

BACKGROUND:RICAMIS trial (The Remote Ischemic Conditioning for Acute Moderate Ischemic Stroke) has demonstrated efficacy of remote ischemic conditioning (RIC) in acute ischemic stroke. We conducted a post hoc analysis of RICAMIS to investigate whether large artery atherosclerosis (LAA) subtype contributed to the outcomes.METHODS:This is a post hoc analysis of the RICAMIS trial.

Researchers have discovered that turning brain immune cells into neurons successfully restores brain function after stroke-like injury in mice. These findings suggest that replenishing neurons from immune cells could be a promising avenue for treating stroke in humans.

Investigators found that an artificial intelligence (AI) algorithm can detect an abnormal heart rhythm in people not yet showing symptoms. The algorithm, which identified hidden signals in common medical diagnostic testing, may help doctors better prevent strokes and other cardiovascular complications in people with atrial fibrillation -- the most common type of heart rhythm disorder.

Pulmonary vein isolation (PVI) is increasingly utilized for the treatment of atrial fibrillation (AF).1 One method of achieving PVI is cryoablation, which has demonstrated comparable success to radiofrequency ablation, but does present unique challenges.

“Atrial fibrillation begets atrial fibrillation” describes the experimental observation, that artificial maintenance of atrial fibrillation (AF) leads to a marked shortening of atrial effective refractory period, and increase in inducibility and stability of AF, which is completely reversible within one week of sinus rhythm (1). In addition to these electrophysiological and reversible changes, which occur relatively early during AF, AF has been shown to be also associated with cardiac structural

BACKGROUND:High-quality research in cardiovascular prevention, as in other fields, requires inclusion of a broad range of data sets from different sources. Integrating and harmonizing different data sources are essential to increase generalizability, sample size, and representation of understudied populations—strengthening the evidence for the scientific questions being addressed.METHODS:Here,

BACKGROUND:Homozygous familial hypercholesterolemia is a genetic disease characterized by extremely high levels of low-density lipoprotein cholesterol (LDL-C) and a high risk of premature cardiovascular events. Phase 2 of ORION (A Study of Inclisiran in Participants With Homozygous Familial Hypercholesterolemia) showed that inclisiran, a small interfering RNA that prevents production of the hepatic PCSK9 protein (proprotein convertase subtilisin/kexin type 9), could

BACKGROUND:Previous ischemic stroke (IS) is a risk factor for subsequent IS in the general population; it is unclear if this relationship remains true in patients with cancer. Our objective was to examine the association between previous IS and risk for future IS in individuals newly diagnosed with cancer.METHODS:We conducted a retrospective population-based matched cohort study of newly diagnosed adult cancer patients (excluding no
