Clinical Features Associated with 'Normal Range' Fibrin D-Dimer Levels in Atrial Fibrillation Patients with Left Atrial Thrombus.

Background: Left atrial thrombus (LAT) often complicates with atrial fibrillation (AF). The evidence whether fibrin D-dimer levels could be used as a predictive biomarker for LAT is contradictory. This study firstly investigated the relationship between 'normal range' D-dimer and prevalent LAT.

Prevalence of recommended anticoagulation by guidelines preadmission and its impact on the incidence of acute myocardial infarction (AMI) and in-hospital outcomes after AMI in atrial fibrillation patients.

This study was designed to explore the prevalence of recommended anticoagulation by guidelines before admission and its impact on the incidence of acute myocardial infarction (AMI) and the AMI associated in-hospital outcomes in patients with atrial fibrillation (AF). 10,725 patients with AF at their first hospitalizations in our hospitals were retrospectively reviewed, with a prevalence of recommended anticoagulation preadmission 24.41% (Number = 2618).

Validating scores predicting atrial fibrillation recurrence post catheter ablation in patients with concurrent atrial fibrillation and pulmonary diseases.

Background: Several scores were available for predicting atrial fibrillation (AF) recurrence post radiofrequency ablation. However, the role of different scores predicting AF recurrence after ablation in patients with concurrent AF and pulmonary diseases (PDs) remained obscure. Herein, we aimed to investigate their predicting values and differences in patients with concurrent AF and PDs.

Patients with acute myocardial infarction and atrial fibrillation: association of anaemia with risk of in-hospital bleeding, stroke and other death causes.

Purposes: To explore the association of anaemia with risk of outcomes of in-hospital patients with acute myocardial infarction (AMI) and atrial fibrillation (AF).

Methods: Patients with AF and AMI at their first hospitalizations in three hospitals (Beijing Tongren Hospital, Beijing Friendship Hospital, Capital Medical University and China-Japan Friendship Hospital) were retrospectively reviewed and divided into two groups (with vs. without anaemia) according to haemoglobin within one day before or after admission.

Fully Automatic Segmentation and Three-Dimensional Reconstruction of the Liver in CT Images.

Automatic segmentation and three-dimensional reconstruction of the liver is important for liver disease diagnosis and surgical treatment. However, the shape of the imaged 2D liver in each CT image changes dramatically across the slices. In all slices, the imaged 2D liver is connected with other organs, and the connected organs also vary across the slices.

Removal of noise and radial lens distortion during calibration of computer vision systems.

The calibration of computer vision systems that contain the camera and the projector usually utilizes markers of the well-designed patterns to calculate the system parameters. Undesirably, the noise and radial distortion exist universally, which decreases the calibration accuracy and consequently decreases the measurement accuracy of the related technology. In this paper, a method is proposed to remove the noise and radial distortion by registering the captured pattern with an ideal pattern.

Polyphenols in Regulation of Redox Signaling and Inflammation During Cardiovascular Diseases.

Cardiovascular diseases remain one of the major health problems worldwide. The worldwide research against cardiovascular diseases as well as genome wide association studies were successful in indentifying the loci associated with this prominent life-threatening disease but still a substantial amount of casualty remains unexplained. Over the last decade, the thorough understanding of molecular and biochemical mechanisms of cardiac disorders lead to the knowledge of various mechanisms of action of polyphenols to target inflammation during cardiac disorders.

[Mild hypothermia therapy for brain recovery after cardiopulmonary resuscitation and analysis of prognostic factors].

Objective: To explore the prognostic factors of mild hypothermia therapy in patients after cardiopulmonary resuscitation (CPR) and the prognostic value of the active electroencephalogram (AEEG).

Methods: Mild hypothermia therapy was applied in 42 patients after CRP whose circulation was stable on the basis of systemic treatment. Body temperature (jugular bulb temperature) was controlled at 31-34 centigrade for 3-6 days before rewarming.
