Pericardial SCUBE1 levels may help predict postoperative results in patients operated on for coronary artery bypass graft surgery.

Cardiovasc J Afr 2021 Jul 5;32:1-5. Epub 2021 Jul 5.

Cardiovascular Surgery Department, Trakya University, Edirne, Turkey.

Introduction: Signal peptide-CUB epidermal growth factorlike domain-containing protein (SCUBE1) is a newly described, secretable and measurable cellular surface protein associated with atherosclerotic lesions in humans, which may be involved in hypertension and cardiovascular pathologies. We aimed to detect normal SCUBE1 levels in pericardial fluid and investigate the effects of SCUBE1 values on postoperative outcomes after coronary artery bypass surgery.

Radial artery as a second conduit gains momentum: The RAPCO trial.

Glob Cardiol Sci Pract 2021 Jun 30;2021(2):e202110. Epub 2021 Jun 30.

Cardiac Surgery Department, Aswan Heart Centre, Aswan, Egypt.

In coronary artery bypass grafting (CABG), the use of an internal mammary artery (IMA) to graft the left anterior descending coronary artery (LAD) improves survival and reduces the need for repeat revascularization. The other IMA, radial artery (RA), and saphenous vein (SV) have contested to complete the surgical revascularization. For that purpose, SV remains the most commonly used conduit despite current evidence in favor of arterial grafts. Read More

Successful percutaneous treatment of a catastrophic left internal mammary artery graft avulsion occurring 4 weeks post-coronary artery bypass grafting surgery: a case report.

Eur Heart J Case Rep 2021 Feb 22;5(2):ytaa524. Epub 2020 Dec 22.

Department of Cardiology, Frimley Health NHS Foundation Trust, Portsmouth Rd, Camberley GU16 7UJ,UK.

Background: Avulsion of the left internal mammary artery (LIMA) graft near the anastomosis to the left anterior descending artery (LAD) artery post-coronary artery bypass grafting (CABG) is a rare but potentially catastrophic complication which can result in sudden ischaemia, haemodynamic compromise and life-threatening bleeding into the pericardium.

Case Summary: We report a case of a spontaneous LIMA graft avulsion at the site of the anastomosis to the LAD artery, which occurred 4 weeks post-conventional CABG surgery and resulted in anterior myocardial infarction (MI), cardiac tamponade and cardiogenic shock. This life-threatening event was treated by deploying a covered stent in the LAD artery and by coiling the dehisced LIMA graft. Read More

Surgical Management of Failed Revascularization in Moyamoya Vasculopathy.

Front Neurol 2021 29;12:652967. Epub 2021 Jun 29.

Department of Neurosurgery, Charité-Universitätsmedizin Berlin (Corporate Member of Freie Universität Berlin, Humboldt-Universität zu Berlin, and Berlin Institute of Health), Berlin, Germany.

Moyamoya vasculopathy (MMV) is a rare stenoocclusive cerebrovascular disease associated with increased risk of ischemic and hemorrhagic stroke, which can be treated using surgical revascularization techniques. Despite well-established neurosurgical procedures performed in experienced centers, bypass failure associated with neurological symptoms can occur. The current study therefore aims at characterizing the cases of bypass failure and repeat revascularization at a single center. Read More

Impact of Musculoskeletal Limitations on Cardiac Rehabilitation Participation.

Front Cardiovasc Med 2021 28;8:688483. Epub 2021 Jun 28.

Cardiovascular Rehabilitation Program, Department of Cardiovascular Diseases, Mayo Clinic, Rochester, MN, United States.

To help clarify a potential barrier to cardiac rehabilitation (CR) participation we sought to examine the association between musculoskeletal limitations (MSLs) and CR enrollment and participation. Consecutive CR eligible individuals hospitalized for a cardiac event (myocardial infarction, percutaneous coronary intervention, and/or coronary artery bypass graft) between the months of November 2007 and May 2008, were asked to complete a mailed survey within 2 weeks after hospital discharge, assessing demographic factors, Patient Health Questionnaire (PHQ-9), participation in CR and MSLs through a validated MSLs screening tool. CR enrollment rates were compared between patients with and without MSLs. Read More

Left Ventricular Function Changes Induced by Moderate Hypothermia Are Rapidly Reversed After Rewarming-A Clinical Study.

Crit Care Med 2021 Jul 1. Epub 2021 Jul 1.

1 Institute of Clinical Medicine, Faculty of medicine, University of Oslo, Oslo, Norway. 2 Division of Emergencies and Critical Care, Department of Research and Development, Oslo University Hospital, Oslo, Norway. 3 Department of Cardiology, Oslo University Hospital, Oslo, Norway. 4 Division of Emergencies and Critical Care, The Intervention Centre, Oslo University Hospital, Oslo, Norway. 5 Department of Cardiothoracic Surgery, Oslo University Hospital, Oslo, Norway.

Objectives: Targeted temperature management (32-36°C) is used for neuroprotection in cardiac arrest survivors. The isolated effects of hypothermia on myocardial function, as used in clinical practice, remain unclear. Based on experimental results, we hypothesized that hypothermia would reversibly impair diastolic function with less tolerance to increased heart rate in patients with uninsulted hearts. Read More

Ticagrelor: clinical development and future potential.

Rev Cardiovasc Med 2021 Jun;22(2):373-394

Department of Infection, Immunity and Cardiovascular Disease, University of Sheffield, S10 2RX Sheffield, UK.

Platelets participate centrally in atherothrombosis, resulting in vessel occlusion and ischaemia. Consequently, optimisation of antiplatelet regimens has the potential to further reduce the residual burden of morbidity and mortality associated with atherosclerosis. Ticagrelor is a potent oral platelet P2Y receptor antagonist that (1) inhibits a central amplification pathway of platelet activation directly as well as via an active metabolite, (2) has a rapid onset and offset of antiplatelet action that remains consistent in the circulation during twice-daily administration and is amenable to reversal, (3) has inverse agonist properties, and (4) demonstrates pleiotropic effects that contribute to anti-thrombotic, anti-inflammatory and vasodilatory properties.

Mechanisms, Prevention and Treatment of Saphenous Vein Graft Disease.

Am J Cardiol 2021 Jul 10. Epub 2021 Jul 10.

Department of Interventional Cardiology and Angiology, National Institute of Cardiology, Warsaw, Poland.

Saphenous vein grafts are imperfect yet indispensable conduits commonly used for coronary artery bypass grafting. Their degeneration ultimately leading to occlusion results from the pathological response of the vein to altered blood rheology and several types of vascular injury. Surgical techniques minimizing vessel damage, and prolonged antiplatelet and lipid-lowering treatment are established methods of mitigating the degeneration process hence preventing graft occlusions.

Effect of the oXiris membrane on microcirculation after cardiac surgery under cardiopulmonary bypass: study protocol for a randomised controlled trial (OXICARD Study).

BMJ Open 2021 Jul 9;11(7):e044424. Epub 2021 Jul 9.

Anesthesiology and Critical Care, CHU Amiens-Picardie, Amiens, France.

Introduction: Cytokine storm and endotoxin release during cardiac surgery with cardiopulmonary bypass (CPB) have been related to vasoplegic shock and organ dysfunction. We hypothesised that early (during CPB) cytokine adsorption with oXiris membrane for patients at high risk of inflammatory syndrome following cardiac surgery may improve microcirculation, endothelial function and outcomes.

Methods And Analysis: The Oxicard trial is a prospective, monocentric trial, randomising 70 patients scheduled for cardiac surgery. Read More
