Comparing Real-World Outcomes of Catheter-Directed Thrombolysis and Catheter-Based Thrombectomy in Acute Pulmonary Embolism: A Post PEERLESS Analysis.

Background: The recently published PEERLESS trial compared catheter-directed thrombolysis (CDT) and catheter-based thrombectomy (CBT) in acute pulmonary embolism (PE). However, it included a low proportion of patients with contraindications to thrombolytic therapy (4.4%), leaving uncertainty about how CDT would perform relative to CBT in a real-world cohort with higher bleeding risk.

Low left ventricular outflow tract velocity time integral predicts normotensive shock in patients with acute pulmonary embolism.

In this study, we found that a low LVOT VTI (<15 cm), a simple bedside point-of-care measurement, predicts normotensive shock in patients with acute intermediate-risk PE.

New Approaches to Target Inflammation in Heart Failure: Harnessing Insights from Studies of Immune Cell Diversity.

Despite mounting evidence implicating inflammation in cardiovascular diseases, attempts at clinical translation have shown mixed results. Recent preclinical studies have reenergized this field and provided new insights into how to favorably modulate cardiac macrophage function in the context of acute myocardial injury and chronic disease. In this review, we discuss the origins and roles of cardiac macrophage populations in the steady-state and diseased heart, focusing on the human heart and mouse models of ischemia, hypertensive heart disease, and aortic stenosis.
