Endoplasmic Reticulum Is Involved in Myocardial Injury in a Miniature Swine Model of Coronary Artery Stenosis Exposed to Acceleration-Associated Stress.

This study aimed to investigate the effects of myocardial injury in a minimally-invasive miniature swine model with different levels of coronary artery stenosis (CAS) and exposed to maximal tolerated +Gz. Proximal left anterior descending branch was ligated in 20 swine. Five swine underwent a sham operation.

PPARG, AGTR1, CXCL16 and LGALS2 polymorphisms are correlated with the risk for coronary heart disease.

Purpose: Our study was designed to explore the interaction between genes of PPARG, AGTR1, CXCL16 and LGALS2 and further investigate the association between genes polymorphisms and coronary heart disease (CHD).

Methods: 90 CHD patients and 80 healthy individuals were enrolled in our study. Gene chip technology was used for checking four single nucleotide polymorphisms (SNPs) (PPARG rs1152002, AGTR1 rs5186, CXCL16 rs3744700 and LGALS2 rs7291467).

Modification of atrioventricular node in a special condition treating paroxysmal supraventricular tachycardia.

Modification of atrioventricular node is a usual and necessary operation to cure atrioventricular nodal reentrant tachycardia (AVNRT). In this operation, atrioventricular block is the most severe complication and its prevention is of our great concern. This complication always occurs under some special circumstances with potential risk.

Successfully ablated atrioventricular nodal reentrant tachycardia in unconventional presentation.

Background: #ENTITYSTARTX02014; Sometime, it's difficult to distinguish the electrophysiological mechanism of some tachycardia, and so, influencing the efficacy and safety of ablation operation. Therefore, it's helpful to analysis some tachycardia in particular mechanism, as in this case.

Methods And Results: #ENTITYSTARTX02014; A 49 years old Chinese male patient had a history of paroxysmal palpitation for 25 years, and recurred more frequently in the month before admission.

[Brain natriuretic peptide and left ventricular remodeling after emergency percutaneous coronary intervention in acute myocardial infarction patients].

Objective: To investigate the effect of emergency percutaneous coronary interventional (PCI) treatment on plasma brain natriuretic peptide (BNP) levels and left ventricular remodeling in patients with acute myocardial infarction (AMI).

Methods: This study included 118 patients with AMI and 20 healthy volunteers (their results were regarded as normal reference). Fifty-two patients who underwent successful emergency PCI 6-12 hours after onset were named as PCI group, and 66 patients rejected or in whom emergency PCI failed served as the control group.

[Mechanism of percutaneous myocardial laser revascularization in the treatment of experimental cardiac ischemia].

Objective: To evaluate the cardiac angiogenesis after percutaneous myocardial laser revascularization (PMR).

Methods: The left anterior descending coronary arteries of 10 healthy mongrel dogs weighing 14 - 18 kg were ligated partially so as to construct a model of chronic cardiac ischemia. Then the dogs were randomly divided into 2 groups of 5 dogs: PMR and control groups.
