Profile and outcomes of patients with mediastinal hematoma after cardiac catheterization: A retrospective analysis.

Objective: To provide a comprehensive introduction of mediastinal hematoma.

Background: Mediastinal hematoma is a rare complication that is usually not considered in the differential diagnosis of chest pain after cardiac catheterization.

Methods: From January 1, 2006, to December 31, 2013, at Fuwai Hospital, 126,265 patients underwent coronary angiography (CAG); 121,215 of them underwent CAG via the radial artery.

[Two types of exercise-induced abnormal blood pressure response in hypertrophic cardiomyopathy].

Insufcient exercise blood pressure response(blunted ABPR) and lower blood pressure during the recovery period (LBP)after exercise are common abnormalities in patients with hypertrophic cardiomyopathy (HCM). The purpose of this study was to analyze the related factors of these two types of abnormal blood pressure response in HCM patients and their relationship with cardiopulmonary function. A total of 219 consecutive HCM patients who underwent CPET in Fuwai hospital were recruited from April 1, 2018 to Jan 31, 2020 with a complete clinical assessment, including electrocardiography, HOLTER, rest echocardiography and cardiac MRI.

Impacts of smoking status on the clinical outcomes of coronary non-target lesions in patients with coronary heart disease: a single-center angiographic study.

Background: Coronary atherosclerotic plaque could go through rapid progression and induce adverse cardiac events. This study aimed to evaluate the impacts of smoking status on clinical outcomes of coronary non-target lesions.

Methods: Consecutive patients with coronary heart disease who underwent two serial coronary angiographies were included.

The relationship between β -adrenergic and M -muscarinic receptor autoantibodies and hypertrophic cardiomyopathy.

New Findings: What is the central question of this study? The concentrations of β -adrenergic receptor and M -muscarinic receptor autoantibodies in hypertrophic cardiomyopathy (HCM) patients and the relationship between the cardiac autoantibodies and clinical manifestations of HCM have rarely been reported. What is the main finding and its importance? We found that the concentrations of the two autoantibodies in HCM patients were significantly higher than those in control subjects. Furthermore, we found that the concentrations of the two autoantibodies could reflect myocardial injury and diastolic dysfunction in HCM patients to some extent and might be involved in the occurrence of arrhythmia.

Abnormalities of myocardial perfusion and glucose metabolism in patients with isolated left ventricular non-compaction.

Background: The prevalence of myocardial perfusion and glucose metabolic abnormalities and their significance in patients with isolated left ventricular non-compaction (ILVNC) have not been well investigated.

Methods: Seventeen ILVNC patients who underwent cardiac magnetic resonance (CMR) and (99m)Tc-sestamibi SPECT/fluorine-18 deoxyglucose ((18)F-FDG) PET imaging were included. Left ventricular non-compaction, regional wall motion abnormalities, left ventricular ejection fraction (LVEF), and delayed enhancement (DE) were estimated using CMR.

[Incidence of coronary artery disease and outcome of patients with left ventricular noncompaction].

Objective: To analyze the incidence of coronary artery disease (CAD) and outcome of patients with left ventricular noncompaction (LVNC).

Methods: Fifty-one patients with LVNC evaluated by echocardiography and/or cardiac magnetic resonance (CMR) from January 2006 to August 2010 were retrospectively reviewed. Coronary angiography or MDCT was performed for detecting coronary artery disease.

[Protective effect of allicin on human periodontal ligament cells with nicotine-induced oxidative damage].

Objective: To explore the protective effect of allicin on nicotine-induced oxidative damage to human periodontal ligament cells (HPDLCs).

Methods: (1) Establish nicotine-induced oxidative damage model on HPDLCs. Use water-soluble tetrazolium (WST) colorimetric method to find out the nicotine concentration (X) that could inhibit HPDLCs' growth for the following experiments.

[Clinical and echocardiographic characteristics of mitral chordal rupture from 292 hospitalized patients.].

Objective: To analyze the clinical, echocardiographic features and therapy efficacy of patients with ruptured mitral chordae tendineae.

Methods: Clinical data, echocardiographic and pathological results from 292 hospitalized patients with ruptured mitral chordae tendineae were retrospectively analyzed.

Results: There were 99 cases (33.

Comparison of H-H versus Si-H sigma-Bond Coordination and Activation on 16e Metal Fragments. Organosilane, N(2), and Ethylene Addition to the Agostic Complex W(CO)(3)(PR(3))(2) and Dynamic NMR Behavior of the Latter.

Variable-temperature (31)P{(1)H} NMR spectroscopy of the agostic complexes M(CO)(3)(PCy(3))(2) (M = Mo, W) indicates dynamic behavior as evidenced by collapse below -20 degrees C of a singlet to an AB signal plus a shifted singlet. The inequivalency of the phosphines is possibly due to the presence of conformational isomers resulting from hindered rotation of the M-P bond or, less likely, a geometric isomer with pseudo-cis PCy(3) ligands. Further studies on the coordination chemistry of W(CO)(3)(PR(3))(2) (R = iPr, Cy) were performed.
