Spontaneous Coronary Artery Dissection with Cardiogenic Shock in the United States.

Background: Spontaneous coronary artery dissection (SCAD) is defined as a non-traumatic separation of the epicardial coronary artery walls that creates a false lumen. SCAD poses a difficult challenge in management, as decisions regarding revascularization and medical management seem to be tailored to the individual patient. We evaluated and compared outcomes based on cardiogenic shock in patients with SCAD utilizing Nationwide Readmissions Database (NRD) between January 1, 2016, to December 30, 2020.

Spontaneous coronary artery dissection outcomes among pregnant vs. non-pregnant women.

Aims: Spontaneous coronary artery dissection (SCAD) has become increasingly recognized. It accounts for <1-4% of acute coronary syndrome presentations. Overall, however, it makes up over 40% of pregnancy-associated myocardial infarction.

In-hospital complications after MitraClip in patients with heart failure and preserved versus reduced ejection fraction in the United States.

Background: The clinical benefits of transcatheter edge to edge mitral valve repair have been well established in patients with heart failure and severe mitral regurgitation (MR) who have prohibitive surgical risk. In March of 2019, the FDA approved the MitraClip for treatment of selected patients with HF and severe secondary MR. However, the relative outcomes of patients with HFrEF and HFpEF treated with MitraClip are largely unknown.

Predictors and mortality risk of venous thromboembolism in patients with COVID-19: systematic review and meta-analysis of observational studies.

Introduction: Novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection resulting in COVID-19 disease is associated with widespread inflammation and a prothrombotic state, resulting in frequent venous thromboembolic (VTE) events. It is currently unknown whether anticoagulation is protective for VTE events. Therefore, we conducted a systematic review to identify predictors of VTE in COVID-19.

An ethical visualization of the NorthCOVID-19 model.

When modelling epidemics, the outputs and techniques used may be hard for the general public to understand. This can cause fear mongering and confusion on how to interpret the predictions provided by these models. This article proposes a solution for such a model that was created by a Canadian institute for COVID-19 in their region; namely, the NorthCOVID-19 model.
