Outcomes of Early Trans-Carotid Artery Revascularization Versus Carotid Endarterectomy after Acute Neurologic Events.

J Vasc Surg 2022 May 23. Epub 2022 May 23.

Division of Cardiac, Thoracic, and Vascular Surgery, NewYork-Presbyterian Columbia University Medical Center, New York, NY. Electronic address:

Objective: Carotid revascularization within 14 days of a neurologic event is recommended by society guidelines. Transcarotid artery revascularization (TCAR) carries the lowest overall stroke rate for any carotid artery stenting technique; however, outcomes of TCAR within 14 days of a neurologic event have not been directly compared to carotid endarterectomy (CEA).

Methods: We compared 30-day outcomes of symptomatic patients undergoing TCAR and CEA within 14 days of stroke or transient ischemic attack (TIA) from January 2016 to February 2020 using the Society for Vascular Surgery Vascular Quality Initiative (VQI) carotid artery stenting and CEA databases.

Utility of Cardiac Troponins in Patients with Chronic Kidney Disease.

Cardiol Rev 2022 May 26. Epub 2022 May 26.

Division of Nephrology/Department of Medicine, Jacobi Medical Center at Albert Einstein College of Medicine.

Cardiovascular disease is a major cause of death worldwide especially in patients with chronic kidney disease (CKD). Troponin T and troponin I are cardiac biomarkers used not only to diagnose acute myocardial infarction (AMI) but also to prognosticate cardiovascular and all-cause mortality. The diagnosis of AMI in the CKD population is challenging because of their elevated troponins at baseline. Read More

Endothelial Microparticle-Mediated Transfer of microRNA-19b Inhibits the Function and Distribution of Lymphatic Vessels in Atherosclerotic Mice.

Front Physiol 2022 9;13:850298. Epub 2022 May 9.

Department of Cardiology, Center for Cardiovascular Translational Research, Beijing Key Laboratory of Early Prediction and Intervention of Acute Myocardial Infarction, Peking University People's Hospital, Beijing, China.

In recent years, the function of the lymphatic system in atherosclerosis has attracted attention due to its role in immune cell trafficking, cholesterol removal from the periphery, and regulation of the inflammatory response. However, knowledge of the mechanisms regulating lymphangiogenesis and lymphatic function in the pathogenesis of atherosclerosis is limited. Endothelial microparticles carrying circulating microRNA (miRNA)s are known to mediate cell-cell communication, and our previous research showed that miRNA-19b in EMPs (EMP) was significantly increased in circulation and atherosclerotic vessels, and this increase in EMP promoted atherosclerosis.

Chronic treatment with serelaxin mitigates adverse remodeling in a murine model of ischemic heart failure and modulates bioactive sphingolipid signaling.

Sci Rep 2022 May 25;12(1):8897. Epub 2022 May 25.

Division of Cardiology, Department of Internal Medicine, Pauley Heart Center, Virginia Commonwealth University, 1101 East Marshall Street, Room 7-070, Box 980204, Richmond, VA, 23298, USA.

Relaxin is a pleiotropic hormone demonstrated to confer cardioprotection in animal models of myocardial infarction and ischemic heart failure by modulating inflammation, fibrosis and arrhythmogenesis. Several of these pathways in the ischemic myocardium are intricately tied with the downstream signaling of bioactive sphingolipids, which play an active role during post-infarction remodeling. In this current study, we examined the effects of relaxin on sphingosine 1-phosphate (S1P), and the potential benefits of relaxin treatment on cardiac health in a rodent model of ischemic heart failure.

Remuscularization with triiodothyronine and β-blocker therapy reverses post-ischemic left ventricular dysfunction and adverse remodeling.

Sci Rep 2022 May 25;12(1):8852. Epub 2022 May 25.

Division of Cardiology, Department of Medicine, Emory University School of Medicine, 3311 WMRB, 323 WMRB, 101 Woodruff Circle, Atlanta, GA, 30322, USA.

Renewal of the myocardium by preexisting cardiomyocytes is a powerful strategy for restoring the architecture and function of hearts injured by myocardial infarction. To advance this strategy, we show that combining two clinically approved drugs, but neither alone, muscularizes the heart through cardiomyocyte proliferation. Specifically, in adult murine cardiomyocytes, metoprolol, a cardioselective β-adrenergic receptor blocker, when given with triiodothyronine (T3, a thyroid hormone) accentuates the ability of T3 to stimulate ERK1/2 phosphorylation and proliferative signaling by inhibiting expression of the nuclear phospho-ERK1/2-specific phosphatase, dual-specificity phosphatase-5.
