Anzhen Risk Evaluation System for Acute Aortic Syndrome (AZSCORE-AAS): protocol for a multicentre prospective cohort study in northern China.

Introduction: Acute aortic syndrome (AAS) is a group of acute and critical conditions, including acute aortic dissection (AAD), acute intramural haematoma and penetrating aortic ulcer. High mortality and morbidity rates result in a poor patient prognosis. Prompt diagnoses and timely interventions are paramount for saving patients' lives.

Prognostic Value of Left Ventricular Longitudinal Function and Myocardial Fibrosis in Patients With Ischemic and Non-Ischemic Dilated Cardiomyopathy Concomitant With Type 2 Diabetes Mellitus: A 3.0 T Cardiac MR Study.

Background: Poorly controlled type 2 diabetes mellitus (T2DM) is known to result in left ventricular (LV) dysfunction, myocardial fibrosis, and ischemic/nonischemic dilated cardiomyopathy (ICM/NIDCM). However, less is known about the prognostic value of T2DM on LV longitudinal function and late gadolinium enhancement (LGE) assessed with cardiac MRI in ICM/NIDCM patients.

Purpose: To measure LV longitudinal function and myocardial scar in ICM/NIDCM patients with T2DM and to determine their prognostic values.

Development and validation of a nomogram for postoperative severe acute kidney injury in acute type A aortic dissection.

Background: Postoperative acute kidney injury (AKI) is a major complication associated with increased morbidity and mortality after surgery for acute type A aortic dissection (AAAD). To the best of our knowledge, risk prediction models for AKI following AAAD surgery have not been reported. The goal of the present study was to develop a prediction model to predict severe AKI after AAAD surgery.

Massive Bleeding After Surgical Repair in Acute Type A Aortic Dissection Patients: Risk Factors, Outcomes, and the Predicting Model.

Background: Massive bleeding throughout aortic repair in acute type A aortic dissection (ATAAD) patients is a common but severe condition that can cause multiple serious clinical problems. Here, we report our findings regarding risk factors, short-term outcomes, and predicting model for massive bleeding in ATAAD patients who underwent emergent aortic repair.

Methods: A universal definition of perioperative bleeding (UDPB) class 3 and 4 were used to define massive bleeding and comprehensively evaluate patients.

Blood Transfusion and Acute Kidney Injury After Total Aortic Arch Replacement for Acute Stanford Type A Aortic Dissection.

Aim: To evaluate the effect of packed red blood cells (pRBCs), fresh frozen plasma (FFP), and platelet concentrate (PC) transfusions on acute kidney injury (AKI) in patients with acute Stanford type A aortic dissection (ATAAD) with total arch replacement (TAR).

Method: From December 2015 to October 2017, 421 consecutive patients with ATAAD undergoing TAR were included in the study. The clinical data of the patients and the amount of pRBCs, FFP, and PC were collected.

One-stage hybrid procedure for distal aortic arch disease: mid-term experience at a single center.

Background: This study analyzes the outcomes of a one-stage hybrid procedure combining thoracic endovascular aortic repair (TEVAR) with extra-anatomic bypass in patients with distal aortic arch disease.

Methods: This retrospective study collected 103 hybrid procedures combining TEVAR with extra-anatomic bypass (mean age, 62.2±9.

Management of acute type A aortic dissection during COVID-19 outbreak: Experience from Anzhen.

Objectives: We seek to report our management protocol and early outcomes of acute type A aortic dissection (ATAAD) repair during the early phase of coronavirus disease 2019 (COVID-19).

Methods: From January 23 to April 30, 2020, we performed ATAAD repair for 33 patients, including three with pregnancy-related TAADs. Confirmation of COVID-19 depended on the results of two nucleic acid tests and pulmonary computed tomography scan.

Identification of Vinculin as a Potential Diagnostic Biomarker for Acute Aortic Dissection Using Label-Free Proteomics.

Acute aortic dissection (AAD) is an emergent vascular disease. Currently, its diagnosis depends on clinical and radiological investigations but lacking of serum biomarkers. In this study, we aimed to identify potential serum biomarkers for AAD using label-free proteomics approach.

Successful repair of acute type A aortic dissection during pregnancy at 16 gestational week with maternal and fetal survival: A case report and review of the literature.

Background: Aortic dissection during pregnancy is a rare but life-threatening event for mothers and fetuses. It often occurs in the third trimester of pregnancy and the postpartum period. Most patients have connective tissue diseases such as Marfan syndrome.

Surgical repair of cervical aortic arch: An alternative classification scheme based on experience in 35 patients.

Objective: Cervical aortic arch (CAA) is rare and difficult to repair. Clinical experience is limited. We report the surgical techniques and midterm outcomes in 35 patients with CAA based on an alternative classification scheme.

Frozen elephant trunk with modified arch reconstruction and left subclavian transposition for chronic type A dissection.

Background: Several methods of arch vessel reconstruction, such as (island) and branched graft techniques, have been proposed to treat aortic arch pathologies during total arch replacement (TAR). We seek to review our experience with modified en bloc technique and left subclavian (LSCA)-left carotid artery (LCCA) transposition in TAR and frozen elephant trunk (FET) procedure for chronic type A aortic dissection (CTAAD).

Methods: From September 2010 to September 2016, 35 consecutive patients with CTAAD underwent modified arch reconstruction with LSCA-LCCA transposition during TAR and FET procedure.

Design, synthesis and in vitro activities on anti-platelet aggregation of 4-methoxybenzene-1,3-isophthalamides.

On the purpose of searching for the structure-activity relationship (SAR) and obtaining novel anti-platelet drugs, 41 4-methoxybenzene-1,3-isophthalamides have been described the synthesis process and in vitro activities on anti-platelet aggregation. The target compounds have been classified into four series: series 1 (ortho-substituted phenyl: 1a-1j), series 2 (meta-substituted phenyl: 2a-2k), series 3 (para-substituted phenyl: 3a-3l) and series 4 (aromatic of no substituted group and aromatic heterocyclic substituted groups: 4a-4h). The chemical structures of the target compounds were confirmed by MS, IR, (1)H NMR, and their in vitro activities on anti-platelet aggregation were tested and assessed by using Born test.
