HMG-CoA reductase inhibitors (statins) have been shown to improve the endothelial function by lowering lipids. Recent studies also suggest a direct impact of statins on the vascular wall. We assessed the rapid effect of cerivastatin on the coronary flow velocity reserve (CFVR) using transthoracic Doppler echocardiography (TTDE). The coronary flow velocity from the distal left anterior descending artery was measured in 16 healthy subjects (all male, age 24-38 years) using a 5-MHz transducer, on the day before, just before, and 3 h after administering 0.3 mg of cerivastatin. Hyperemia was achieved by the intravenous administration of adenosine, and the CFVR was calculated as the radio of the mean diastolic hyperemic coronary flow velocity to the basal flow velocity. The serum lipid profile and high-sensitivity C-reactive protein (hsCRP) were measured. The CFVR following the single administration of cerivastatin increased from 2.93+/-0.58 to 3.91+/-0.86, P=0.003, and was significantly higher than the CFVR measured at the same time on the previous day (3.91+/-0.86 vs 3.37+/-0.48, P=0.009). Neither the serum lipid profile nor hsCRP exhibited a remarkable change after cerivastatin administration. We concluded that a single-dose administration of cerivastatin, an HMG-CoA reductase inhibitor, improves the coronary flow velocity reserve without modifying the serum lipid profile.

Background: Benign and malignant breast tumors differ in their microvasculature morphology and distribution. Histologic biomarkers of malignant breast tumors are also correlated with the microvasculature. There is a lack of imaging technology for evaluating the microvasculature.

Introduction: Sodium Glucose cotransporter-2 inhibitors (SGLT2is) possess pleiotropic effects, such as antioxidant, antifibrotic, anti-inflammatory, and vascular remodeling activities. Considering the lack of literature, a network meta-analysis was conducted to explore the impact of SGLT2is on endothelial dysfunction and arterial stiffness in the diabetic population.
Methods: Electronic databases were searched to identify randomized clinical trials evaluating the effects of SGLT2is on outcomes, such as Flow-mediated Vasodilation (FMV), Pulse Wave Velocity (PWV), and Augmentation Index (AIx).

Objective: To observe the clinical efficacy of 's subcutaneous needling based on "multi-joint muscle spiral balance chain" theory for cervical vertigo (CV) and its effect on blood flow velocity of vertebral artery.
Methods: A total of 60 patients with CV were randomized into a Fu's subcutaneous needling group and a medication group, 30 cases in each one. In the Fu's subcutaneous needling group, 's subcutaneous needling was delivered at Dazhui (GV14), the flexible tube was retained for 5 min after sweeping manipulation, and the treatment was given once every other day, 3 times a week for 3 weeks.

Pipe bends are recognized as critical areas susceptible to wall thinning, a phenomenon instigated by abrupt changes in the fluid flow direction and velocity. Conventional monitoring techniques for bends typically depend on localized ultrasonic measurements of thickness. While these methods are effective, they can be time-consuming compared to the use of permanently installed transducers, a strategy employed in guided wave tomography (GWT).

The effect of acetazolamide on regional brain tissue oxygenation in patients with acute brain injury (ABI) is unknown. We studied adult patients with ABI who received acetazolamide as per the treating physician's decision and had ICP and brain oxygen pressure (PbtO) monitoring. Baseline measurements of ICP, cerebral perfusion pressure (CPP), and PbtO were taken before administering acetazolamide; subsequent measurements were recorded every 5 min for a total of 20 min.
