NCT ID: NCT06370624 Active, not recruiting - Clinical trials for Encephalopathy, Hypoxic-Ischemic

PEDI-REAVASC Resonance Imaging of Infants With Hypoxic Ischemic Encephalopathy After Hypothermia Treatment.

PEDI-REAVASC
Start date: January 17, 2023
Phase: N/A
Study type: Interventional

This study is a prospective, observational, single-center study to assess the correlation between rs-fMRI measures and clinical measures of standard MRI, NIRS, EEG and clinical scores. The target population was neonates with HIE referred to MRI after hypothermia treatment, which was initiated within 6 hours of birth, continued for 72 hours and followed by a slow rewarming period of 6-12 hours. A one-year clinical and imaging follow-up is planned. As the aim of the present study is to assess the predictiveness of the outcome one year after the HIE event, no follow-up is planned.

NCT ID: NCT06365827 Active, not recruiting - Acute Kidney Injury Clinical Trials

Perioperatively Assessed Biomarker I-FABP Level for Prediction of Acute Mesenteric Ischemia and Its Correlation With Acute Kidney Injury, Followed by Extracorporeal Circulation (aMIKI)

aMIKI
Start date: March 1, 2022
Phase:
Study type: Observational [Patient Registry]

Acute mesenteric ischemia (AMI) is a severe condition that might occur after cardiovascular surgery. Several risk factors for AMI, such as multimorbidity, the use of vasopressors, and an increase in inflammatory markers have been identified in the past. However, these risk factors also seem to influence the blood and urine levels of I-FABP. This prospective pilot study intends to evaluate the value of perioperatively assessed I-FABP levels and to correlate these values with clinical or angiographic findings in mesenteric ischemia to improve a standardised diagnosis.

NCT ID: NCT06345573 Active, not recruiting - Myocardial Ischemia Clinical Trials

Heart-brain-axis and Psychosocial Stress

Start date: October 11, 2021
Phase:
Study type: Observational

The main study objective is to prospectively determine the influence of sex-related risk factors and psychosocial variables on neuronal stress responses and myocardial perfusion in a population of 64 female and male individuals 50-75 years of age and free of cardiovascular disease.

NCT ID: NCT06315153 Active, not recruiting - Ischemic Stroke Clinical Trials

Comprehensive Assessment of Atherosclerotic Ischemic Stroke Risk and Development of a Prediction Model

CAIS-pre
Start date: January 3, 2022
Phase:
Study type: Observational [Patient Registry]

This observational study was designed for the assessment of plaque vulnerability in patients with carotid atherosclerotic stenosis and the development of predictive models for the occurrence and recurrence of atherosclerotic ischemic stroke. The objectives of the study were as follows: first, to integrate the degree of carotid stenosis and plaque characteristics assessed by vascular ultrasound for a comprehensive assessment of plaque vulnerability; second, to develop an assessment tool for the risk of future ischemic stroke in patients with asymptomatic carotid stenosis by combining vascular risk factors, serologic markers, carotid ultrasound characteristics, and contrast-enhanced ultrasonographic parameters; and third, to incorporate vascular ultrasound parameters into existing predictive models of ischemic stroke recurrence risk to develop a risk assessment tool for atherosclerotic ischemic stroke. The main questions it aims to answer are: - How to screen high-risk patients and those eligible for revascularization from asymptomatic carotid stenosis patients for primary prevention of stroke. - How to improve the prediction accuracy of atherosclerotic ischemic stroke based on existing prediction models for secondary prevention of stroke.

NCT ID: NCT06235424 Active, not recruiting - Clinical trials for Aortic Valve Disease

Del Nido Versus HTK Cardioplegia in Adult Aortic Valve Replacement

Start date: October 1, 2018
Phase: Phase 4
Study type: Interventional

The goal of this clinical trial is to compare del Nido and Bretschneider-HTK (HTK) cardioplegia solutions in patients undergoing elective aortic valve replacement. The main question it aims to answer is: • Does the del Nido cardioplegia provide better cardioprotection and clinical outcomes than HTK cardioplegia? Participants will receive one of the investigated cardioplegia solutions according to the randomization. Researchers will compare both groups in terms of cardioprotection (described as levels of CK-MB and hsTnI), in-hospital clinical outcomes, biochemical changes in coronary sinus blood and one-year follow-up.

NCT ID: NCT06183567 Active, not recruiting - Anesthesia Clinical Trials

The Effect of Sedoanalgesia and General Anaesthesia on Early Neurological Recovery in Acute Ischaemic Stroke Patients Undergoing Endovascular Thrombectomy

Start date: November 30, 2023
Phase: N/A
Study type: Interventional

The hypothesis of this study is that sedoanalgesia will provide better early neurological recovery than general anaesthesia in acute ischaemic stroke patients undergoing endovascular thrombectomy and to investigate the haemodynamic data of both anaesthetic methods.

NCT ID: NCT06172387 Active, not recruiting - Clinical trials for Acute Ischemic Stroke

Intra-arterial Albumin in Acute Ischemic Stroke After Endovascular Treatment for

Start date: November 1, 2023
Phase: Phase 1
Study type: Interventional

Stroke is an acute focal injury of the central nervous system caused by cerebral vessels. One in every four people is affected by stroke at different times in life. Globally, stroke is the second leading cause of death and third leading cause of disability in adults. we hypothesized that in patients with acute large vessel occlusive ischemic stroke treated with mechanical thrombectomy, the infusion of 20% human serum albumin solution into the revascularization area can exert a stronger neuroprotective effect.

NCT ID: NCT06127134 Active, not recruiting - Angioplasty Clinical Trials

Outcomes of Straight-line Flow Versus Angiosome-targeted Angioplasty in Treatment of Critical Lower Limb Ischemia

Start date: January 1, 2023
Phase: N/A
Study type: Interventional

Peripheral arterial disease (PAD) affects more than 200 million people worldwide. Although over 50% are asymptomatic, it accounts for 4% of all amputations. The ischemic limb must be revascularized to help wound healing, reduce the pain of ischemia and preserve the limb's function. So, surgical and percutaneous revascularization choices must be considered in CLI. Classically, CLI revascularization aims to provide at least one patent vessel that delivers in-line flow to the foot. Today, the investigators live in a new era of angioplasty evolving and substituting open vascular surgery, so expanding research on endovascular strategy has been noticed.This confirms the profound impact of angioplasty in vascular surgery as one of the fastest-growing branches of medicine Infrapopliteal artery occlusive disease (IPOD) is a significant cause of critical limb-threatening ischemia (CLTI). The worldwide prevalence of IPOD is between 4.5% and 29%, and most patients live in low-income countries. The angiosomal concept was derived from plastic surgery for the skin flap. This concept delineates the human body into three-dimensional blocks of tissue from the skin to bone and also provides practical application of vascular anatomy for reconstructive surgery. An angiosome is an anatomic unit of tissue consisting of skin, subcutaneous, muscle, and bone fed by a source artery and drained by a specific vein. According to the angiosomal concept, the foot is divided into six distinct angiosomes fed by source arteries, three from the posterior tibial, two from the peroneal, and one from the anterior tibial artery, with functional artery-to-artery connections among muscle, fascia, and skin. Numerous direct inter-arterial connections occur between the foot's main arteries, which provide alternative pathways of blood flow when disruption or compromise affects the arteries that directly feed the angiosome. On the other hand, in patients with CLI, where only one vessel runoff can be established to the foot, direct flow into a patent pedal arch is essential to improve their clinical outcomes. Conventional Endovascular therapy aims to the re-establishment of pulsatile straight-line flow to the lower limb. This results in relieving ischemic pain, healing ulcers, achieving limb salvage, improving quality of life, and potentially prolonging survival. So it became essential to know the differential impact of both concepts on CLI revascularization.

NCT ID: NCT06071091 Active, not recruiting - Clinical trials for Acute Ischemic Stroke

Permanent Intracranial Stenting for Acute Ischemic Stroke Related to a Refractory Large Vessel Occlusion

PISTAR
Start date: November 8, 2023
Phase: N/A
Study type: Interventional

Clot extraction failure during mechanical thrombectomy is a major concern in the management of acute ischemic stroke related to large vessel occlusions. Indeed, it can occur in up to 10 to 30% of cases and, therefore, is associated with a very poor prognosis. These refractory occlusions frequently occur when an underlying intracranial atherosclerotic disease is present. Thus, one of the most promising rescue technique consists of placing a permanent intracranial stent, under dual antiplatelet therapy over the target refractory occlusion. This strategy is well studied in coronary occlusions where the atheroscotic mechanism is highly prevalent. However, as the ischemiated brain is at much higher risk of hemorrhagic complications, such strategy entails a greater risk. This raises the question of whether such risk is worth the reward of obtaining reperfusion. The investigators designed this randomized study in order to evaluate whether a strategy combining rescue pemanent intracranial stenting with the best medical treatment is superior to the best medical treatment alone in acute refractory large vessel occlusions.

NCT ID: NCT06056193 Active, not recruiting - Clinical trials for Peripheral Arterial Occlusive Disease
