Intradialytic hypotension (IDH) is a global public health problem. A rising number of IDH sufferers resort to Chinese patent medicine, Shengmai Injection (SMI) in China. The objectives of present study are to assess the effectiveness and safety of SMI as an adjunct therapy for IDH.

Background: RFCA has been established as an effective and curative therapy for severely symptomatic PVC from the outflow tract in structurally normal hearts. However, it is unknown whether PVCs originating from the left ventricular septum, are effectively eliminated by RFCA. This study aimed to investigate electrophysiologic characteristics and effects of radiofrequency catheter ablation (RFCA) for patients with symptomatic premature ventricular contraction (PVC) originating from the left ventricular septum without including fascicular PVCs.

This case report describes idiopathic ventricular tachycardia (VT) originating from the anterolateral site of mitral annulus. Radiofrequency (RF) energy application at an endocardial site of mitral annulus could not eliminate the tachycardia. The earliest epicardial activation preceding the onset of the QRS complex by 34 ms was found at the great anterior cardiac vein just opposite to the endocardial ablation catheter, pace mapping provided an identical (12/12) match with the VT morphology at the site, and RF ablation effectively eliminated the VT from the great cardiac vein within the coronary venous system.

We report a case of atrioventricular nodal reentrant tachycardia (AVNRT) coexistent with His bundle anomaly and atrial septal defects. The His-bundle potential was recorded at the coronary sinus (CS) ostium. Fractionated atrial potentials and an A:V electrogram ratio 1:3 were recorded at the anterior septum of the tricuspid annulus approximately 2 cm from CS ostium.

In this study, we examined the protective effects of Danshen both on endothelial progenitor cells (EPCs) in patients with hypercholesterolemia and on in-vitro EPCs of healthy volunteers. In the clinical study, we randomly divided 24 subjects with hypercholesterolemia into two groups (the control group and the Danshen-treated group). At the end of two weeks of treatment, the EPC cellular functions of both groups were tested.

Article Synopsis
  • - The study developed a new canine model using Beagle dogs to investigate cardiac memory through endocardial ventricular pacing via the internal jugular vein.
  • - Out of 12 dogs, 11 successfully exhibited cardiac memory, with the T-wave memory lasting approximately 96 minutes in the short term and up to 31 days in the long term; however, there was one procedural mortality due to complications.
  • - This new model is less invasive compared to traditional open-chest methods, making it a valuable tool for further research into the mechanisms of cardiac memory.

Oxidative stress has been implicated in the pathogenesis of acute myocarditis. The imbalance between the occurrence of reactive oxygen species and the cellular antioxidant defense mechanism plays a key role in myocardial injury of viral myocarditis. Carvedilol, a nonselective beta-adrenoceptor antagonist with additional alpha1-adrenergic blocking and antioxidant properties, has been shown to be cardioprotective in experimental myocarditis.

Pulse pressure (PP) is emerging as a major pressure predictor of cardiac disease. However, there are two major limitations for PP as an evaluation index. First, PP has alterability in the same individual.

A 35-year-old man was referred to the emergency department after having a short syncopal episode while waiting for a Doppler scan of the lower extremities for a 4-week history of a painful right leg. He had no significant past medical history and was a non-smoker. On presentation he had severe chest pain and dyspnea associated with diaphoresis, and was hemodynamically unstable.

Parkinson's disease (PD) is one of the most common neurodegenerative disorders and still remains incurable. New targets for potential pharmacological intervention should be explored and evaluated in order to slow down, delay or reverse the progress of this disease, and/or to avoid the serious side effects of levodopa praeparatum. Potassium (K+) channels widely express in basal ganglia and play crucial roles in the pathophysiology of PD, thereby raising their therapeutic application.

Objective: To study the effects of puerarin on pulmonary Vascular remodeling in rats with pulmonary hypertension induced by chronic hypoxia and hypercapnia.

Method: Forty male rats (180-220) g of grade two were randomly divided into five groups: normal control group (NC), hypoxia-hypercapnia 1, 2, 3 week groups (LH1, LH2, LH3) and hypoxia-hypercapnia 3-week + puerarin group (LHP3 group, puerarin intraperitoneal injection, 20 mg x kg(-1) x d(-1)). Collagen I, III and their mRNA were observed in pulmonary arterioles by the technique of immunohistochemistry and in situ hybridization.

Purpose: To evaluate neovascularization within carotid atherosclerotic plaques with contrast-enhanced sonography.

Methods: We used contrast-enhanced sonography to examine 63 patients with carotid atherosclerotic plaques. The features of neovascularization within the plaques were analyzed and correlated with plaque size and echogenicity.

Carvedilol, a nonselective beta-blocker with additional alpha1-adrenergic blocking and antioxidant properties, has been shown to be cardioprotective in experimental myocarditis. However, the antioxidative effects of carvedilol have not been investigated in the setting of acute viral myocarditis. Therefore, this study investigated whether carvedilol protects against viral myocarditis primarily by its antioxidant and/or antiinflammatory properties.

Objective: To investigate the effects of Compound Salvia injection (CSI) on the number and activity of endothelial progenitor cells (EPCs).

Method: Mononuclear fraction of human umbilical cord blood was obtained by density gradient centrifugation and plated on fibronectin coated culture dishes. Cells were divided in to five groups: group control, group VEGF, group CSI 50, group CSI 10 and group CSI 2 (supplemented with none cytokine, VEGF 10 ng x mL(-1), CSI 50, 10, 2 microg x mL(-1), respectively).
