AI Article Synopsis
- The study aimed to investigate the effects of Shexiang Baoxin pill (SBP) on vascular endothelial function in patients with type 2 diabetes and angina pectoris.
- After randomly assigning 111 patients to either the SBP group or a control group treated with isosorbide mononitrate, they were monitored for angina episodes and vascular changes over 6 months.
- Results showed no significant differences in angina episodes or medication use between the groups, but the SBP group exhibited a notable improvement in endothelium-dependent vascular relaxation after treatment, indicating enhanced endothelial function.
Article Abstract
Objective: To study the effect of Shexiang Baoxin pill (SBP) on the vascular endothelial function in patients with diabetes mellitus type 2 (DM2) complicated with angina pectoris.
Methods: Two weeks after runin, according to the randomizing table, 111 patients were divided into two groups, the XBP group (56 patients) and the control group (55 patients, treated with delayed-released isosorbide mononitrate, DRIM), they were treated for 6 months. In the treatment period, the episodes of angina attack and condition of rescue medication were recorded in the daily card, and brachial arterial changes of endothelium-dependent relaxing function before and after treatment were measured by B-ultrasonography.
Results: Comparison between the two groups in episodes of angina attack and rescue medication were insignificantly different. In the control group, the basal value of brachial arterial inner diameter before and after treatment was 3.68 +/- 0.56 mm and 3.70 +/- 0.58 mm respectively, those before and after responsive congestion was 5.44 +/- 0.81% vs 5.68 +/- 0.83%, and those before and after taking nitroglycerin was 19.8 +/- 4.9% vs 20. +/- 5.2%, all showed insignificant difference (P > 0.05). In the SBP group, the corresponding basal value was 3.73 +/- 0.62 mm vs 3.71 +/- 0.59 mm, and those after taking nitroglycerin 18.8 +/- 4.5 % vs 19.2 +/- 5.8%, also showed insignificant difference, but those before and after responsive congestion (5.69 +/- 0.79 % vs 9.56 +/- 3.82 %) did show significant difference (P < 0.01).
Conclusion: XBP could improve the vascular endothelial function in patients with DM2 complicated with angina pectoris.

Background: The therapeutic management of patients with multivessel disease and severe left ventricular dysfunction is complex and controversial.
Aims: The aim of this study was to analyze the clinical outcomes and the changes in left ventricular ejection fraction (LVEF) in patients with severe left ventricular dysfunction and at least one chronic total occlusion (CTO) undergoing percutaneous coronary intervention (PCI) with hemodynamic support provided by Impella.
Methods: Retrospective, multicenter study enrolling patients with severe left ventricular dysfunction and severe coronary artery disease with at least one CTO who required percutaneous mechanical circulatory support with Impella, from January 2019 to December 2023.

Background: The left internal thoracic artery (LITA) has been widely accepted as the standard for revascularizing the left anterior descending artery during coronary artery bypass grafting (CABG) surgery. However, in 10-20% of cases, the LITA may lead to unsecured side branches to the chest wall, particularly the lateral costal artery (LCA), potentially resulting in postoperative chest angina.
Case Presentation: We report the case of a 58-year-old patient who experienced persistent angina eight months after having undergone coronary artery bypass grafting (CABG) due to the steal phenomenon caused by a thick lateral costal artery (LCA).

Left ventricular (LV) thrombus is a serious complication of myocardial infarction (MI) that can lead to a fetal systemic embolism. Although coronary artery bypass graft surgery (CABG) after MI is widely performed, to our knowledge, there are no reports of LV thrombus in the early postoperative period. Here, we report a rare case of a 70-year-old man who underwent off-pump coronary artery bypass grafting (OPCAB) for unstable angina pectoris with reduced left ventricular ejection fraction (LVEF).

Background: Coronary artery disease (CAD), primarily caused by atherosclerosis, is a leading cause of death, presenting as angina or myocardial infarction. Advances in cardiac imaging, angiography, and procedures like percutaneous coronary intervention (PCI) or coronary artery bypass graft (CABG) surgery have improved early detection and management of this condition. This report presents the case of a man who experienced worsening exertional chest pain and discomfort while at rest.
