The cardiovascular effects of bromocriptine, a dopamine receptor agonist, were investigated in twenty-eight Parkinsonian patients. Bromocriptine caused a significant impairment of postural compensation with a fall in systolic pressure and an absence of the rise in diastolic pressure after standing for 1 min when patients taking active drug were compared to the same patients on placebo. The hypotensive effect persisted for at least 6 weeks of treatment. There was also a significant reduction in supine heart rate. One patient had marked falls in supine and erect blood pressure after a single oral dose of bromocriptine (2.5 mg) and a further patient developed paroxysmal atrial tachyarrhythmias. Both blood pressure and heart rate changes reversed spontaneously after stopping bromocriptine. It is proposed that dopaminergic mechanisms either in the central nervous system or the periphery contribute to cardiovascular regulation in man.

Background: Triglyceride-glucose-BMI (TyG-BMI) index is a surrogate marker of insulin resistance and an important predictor of cardiovascular disease. However, the predictive value of TyG-BMI index in the progression of non-severe aortic stenosis (AS) is still unclear.
Methods: The present retrospective observational study was conducted using patient data from Aortic valve diseases RISk facTOr assessmenT andprognosis modeL construction (ARISTOTLE).

Background: Proton pump inhibitors (PPIs) are commonly used for managing gastroesophageal disorders but concerns about their potential association with increased stroke risk have emerged, especially among patients with pre-existing cardiovascular conditions such as acute coronary syndrome (ACS). This systematic review and meta-analysis aim to assess the risk of stroke associated with PPI use, stratified by the presence or absence of pre-existing CVD.
Methods: This review was conducted following the PRISMA guidelines and included studies up to March 2024 from PubMed, Embase, and Web of Science.
Glucagon like peptide-1 (GLP-1) agonists and cardiometabolic protection: historical development and future challenges.
Cardiovasc Diabetol
January 2025
Faculty of Medicine, Tel Aviv University, Tel Aviv, Israel.
Glucagon-like peptide-1 receptor agonists (GLP-1RAs) have revolutionized the treatment of cardiometabolic diseases, extending their therapeutic applications far beyond glycemic control in type 2 diabetes (T2D) and obesity. This editorial synthesizes key milestones, from the discovery of GLP-1 to recent clinical trials highlighting the pleiotropic effects of GLP-1RAs in addressing the interconnected spectrum of cardiometabolic conditions, with a focus on cardiovascular, renal, and hepatic benefits. In addition, as GLP-1RAs continue to reshape the management of cardiometabolic disease and global public health, we discuss future challenges to better elucidate their mechanisms of cardiometabolic protection and maximize their therapeutic potential.

Department of Respiratory Medicine, The Second Hospital of Jilin University, No. 4026 Yatai street, Changchun, 130041, Jilin, China.
Background: Ectopic thyroid tissue (ETT) is a rare congenital anomaly caused by the abnormal embryonic migration of thyroid tissue, leading to its presence outside its usual pretracheal location. This condition can lead to diagnostic challenges, especially when located within the airway, as it mimics other respiratory disorders such as asthma.
Case Presentation: We report the case of a 69-year-old man with endotracheal ETT presenting with severe dyspnea, and the lesion was initially suspected to be malignant.
Dioscin pretreatment ameliorates ferroptosis in cardiomyocytes after myocardial infarction via inhibiting endoplasmic reticulum stress.

The First People's Hospital of Lin'an District, No. 360, Yikang Street, Jinnan Subdistrict, Lin'an District, Hangzhou, Zhejiang, 311300, China.
Background: Myocardial infarction (MI) remains a leading cause of mortality globally, often resulting in irreversible damage to cardiomyocytes. Ferroptosis, a recently identified form of regulated cell death driven by iron-dependent lipid peroxidation, has emerged as a significant contributor to post-MI cardiac injury. The endoplasmic reticulum (ER) stress response has been implicated in exacerbating ferroptosis.
