Cellular cardiomyoplasty using various types of donor cells is now validated by a large number of experimental studies. We report a case of cellular cardiomyoplasty performed on a beating heart using autologous skeletal myoblasts, thus combining the efficacy of both procedures. Approximately 2.5 g of rectus femoris muscle tissue biopsy was taken from the patient and cultured using a patented procedure to generate human myoblasts. The cell type and the purity of the cell culture were ascertained by immunostaining for human desmin expression. Under direct vision and stabilization with the Octopus III tissue stabilizer, 3.70 x 10(8) myoblasts in 3 ml of the patient's own serum were injected into the myocardium in 20 sites on the anterior wall and near the apex on the posterior wall, in and around the infarcted areas. In this case report, this procedure was found to be a safe and viable option, with improvement in cardiac function.

Angiotensin 1-7 injected into the rat paraventricular nucleus of hypothalamus increases blood pressure and heart rate via various receptors.

Although angiotensin 1-7 (Ang 1-7) and its role as a part of the "protective" axis of the renin-angiotensin system are well described in the literature, the mechanisms of its angiotensin II-like pressor and tachycardic effects following its acute central administration are not fully understood. It was the aim of the present study to examine which receptors contribute to the aforementioned cardiovascular effects. Ang 1-7 and antagonists for glutamate, GABA, vasopressin, thromboxane A (TP), α-adrenergic, and P2X purinoceptors or modulators of oxidative stress were injected into the paraventricular nucleus of the hypothalamus (PVN) of urethane-anesthetized male Wistar rats.

Objective: Heart rate serves as a critical prognostic factor in heart failure (HF) patients. We hypothesise that elevated heart rate in critically ill HF patients on discharge from the intensive care unit (ICU) could be linked to adverse outcomes.
Design: A single-centre retrospective cohort study.
A Novel Transcatheter Posterior Ventricular Anchoring Neochordoplasty Mitral Valve Repair Device.
Cardiovasc Eng Technol
December 2024
Department of Cardiothoracic Surgery, Stanford University, Stanford, CA, USA.
Purpose: Advancements in minimally invasive technologies to decrease postoperative morbidity and recovery times represent a large opportunity for mitral valve repair operations. However, current technologies are unable to replicate gold standard surgical neochord implantation.
Methods: We developed a novel neochordal repair device, Minimally Invasive Ventricular Anchoring Neochordoplasty (MIVAN), which operates via transcatheter, trans-septal anchoring to the posterior ventricular wall.
The Impact of BMI on Heart Rate During Suspension Laryngoscopy Operation in Patients With Laryngeal Lesions: A Prospective Cohort Study.

Department of Otolaryngology Head and Neck Surgery, West China Hospital, Sichuan University, Chengdu, Sichuan, China. Electronic address:
Objectives: Suspension laryngoscopy can trigger vagal reflexes, leading to a decrease in heart rate, a phenomenon that is more common in patients with a high body mass index (BMI). This study aims to systematically evaluate the effect of BMI on heart rate during suspension laryngoscopy (SL-HR) in patients with laryngeal lesions.
Methods: We employed univariate generalized linear regression and stratified analyses to assess the relationship between BMI and changes in SLHR, adjusting for confounders such as age, gender, intubation type, and depth.
Stroke Volume Augmentation Improves with PH-Targeted Therapy in Patients with Exercise-Induced Pulmonary Hypertension.

Unlabelled: Exercise-induced pulmonary arterial hypertension (EiPH) is often treated with off-label use of pulmonary arterial hypertension-targeted therapy (PH-targeted therapy). Most measures of PAH severity are normal in patients with EiPH, posing challenges in evaluating for physiological improvement in patients treated for EiPH. In this study, we used non-invasive cardiopulmonary exercise testing (CPET) to assess for objective improvement in patients treated for EiPH.
