Objective: To analyze correlation factors of hemodynamic damage after carotid artery stenting.
Methods: In this study, 66 cases (71 lesions) who undertook carotid artery stenting were collected and the correlation factors of hemodynamic damage were analyzed.
Results: Hemodynamic damage emerged in 23 cases (32.4%), of which, 11.3% developed hypotension. The distance between bifurcation and lesions (P=0.0020), plaque distribution (P=0.0002), plaque character (P=0.0019), post-dilation (P=0.0026) were associated with hemodynamic damage by single factor analysis. However, only eccentric plaque (P=0.0153) and calcified plaque (P=0.0097) were associated with hemodynamic damage by multiple factors analysis. All the patients could reach stable circulation by drugs during operation, and no cerebral ischemic events (transient ischemic attack or stroke) and cardiovascular ischemic events happened.
Conclusion: The distance between bifurcation and lesions, eccentric plaques, calcified plaques are correlation factors of hemodynamic damage.

Introduction: Road traffic accidents (RTA) account for a sizable portion of morbidity and mortality globally, with a particularly high incidence among young and active individuals. Patients presenting with polytrauma require a multidisciplinary approach guided by protocols for advanced trauma life support.
Case Report: We report the case of a 31-year-old female, transferred-in to our center following primary care after an RTA on June 17th, 2023.

As several decades of research have shown the cardioprotective effects of angiotensin-converting enzyme (ACE) inhibitors alone or in combination with diuretics, we were interested in investigating the effects of subchronic therapy of these drugs on ischemia-reperfusion (I/R) damage to the heart, as well as their influence on oxidative status. The research was conducted on 40 spontaneously hypertensive male Wistar Kyoto rats, divided into 4 groups. Animals were treated for four weeks with 10 mg/kg/day zofenopril alone or in combination with hydrochlorothiazide, indapamide and spironolactone per os.

Growth hormone (GH) signaling is essential for heart development. Both GH deficiency and excess raise cardiovascular risk. Human (h) and mouse (m) GH differ structurally and functionally: hGH binds both the GH receptor (GHR) and prolactin receptor (PRLR), whereas mGH binds only GHR; thus, there is the potential for differential effects.

Background: Continuous retrograde flow across the aortic valve from left ventricular assist device (LVAD) therapy can result in cusp damage and progressive aortic regurgitation, potentially triggering recurrent heart and multiorgan failure. The management of aortic regurgitation after LVAD implantation has not been well defined.
Methods: This study retrospectively reviewed the investigators' experience with the management of de novo aortic regurgitation requiring intervention in patients with continuous-flow LVAD.

The importance of central hemodynamic metrics such as Central blood pressure (CBP), which directly measure the pressure exerted by the cardiac muscle on the major arteries, offering a more direct assessment of cardiovascular workload compared to brachial blood pressure (bBP), which measures pressure against the walls of peripheral arteries. This review consolidates findings that evaluate the correlation between CBP and key markers of aortovascular disease. The growth of thoracic aortic aneurysm (TAA) is a significant component of aortovascular assessment.
