NCT ID: NCT04993664 Withdrawn - Inflammation Clinical Trials

Influence of Pelacarsen on Patients After Myocardial Infarction With High Lp(a) Values (PEMILA)

Start date: October 1, 2021
Phase: N/A
Study type: Interventional

The aim of study is to examine the relationship between lipid subfractions, inflammation and structural-functional properties of the arterial wall in patients after myocardial infarction with high lipoprotein (a) (Lp (a)) levels, to study genetic polymorphisms that determine lipid subfractions concentration on the functional and morphological properties of the arterial vascular wall in patients after myocardial infarction with high Lp (a) levels, to study the effect of pelacarsen on lipid subfractions, inflammation and structural-functional properties of arterial wall in patients after myocardial infarction with high Lp (a) levels and to study the influence of NOS-3 gene expression on the functional and morphological properties of the arterial vascular wall in the same patients. Impaired blood fat metabolism and chronic inflammation represent possible causes of atherosclerosis. Lp (a) is an independent risk factor for cardiovascular disease and a prognostic predictor in patients after myocardial infarction. Despite recommended screening for elevated Lp (a), there is no specific drug treatment approved to reduce cardiovascular risk through lowering Lp (a). Besides subtilisin-kexin convertase type 9 (PCSK9) inhibitors, antisense oligonucleotides (ASOs) are currently only therapeutic agents that significantly reduce serum Lp (a) concentration. Pelacarsen by using an ASO directed against the messenger ribonucleic acid (mRNA) of apolipoprotein (a), reduces the production of apolipoprotein (a) in the liver and thus, the level of Lp (a). However, there are no data on the relationship between Lp (a) values and polymorphisms for Lp (a), indicators of inflammation and impaired arterial function, and response to treatment with pelacarsen in patients after myocardial infarction with extremely high Lp (a) levels.

NCT ID: NCT04509180 Withdrawn - Clinical trials for Persistent Atrial Fibrillation

Comparison of Treatment Outcomes Between Convergent Procedure and Catheter Ablation for Persistent and Longstanding Persistent Atrial Fibrillation

Start date: February 26, 2021
Phase: N/A
Study type: Interventional

In the last 20 years, atrial fibrillation has become one of the leading healthcare burden in Europe and other developed countries. With an ever-increasing prevalence and incidence, atrial fibrillation is expected to remain a significant problem in the near future. Due to numerous detrimental effects atrial fibrillation has on the patient's health, having an efficient and safe treatment is crucial for managing the problem. The gold standard for an atrial fibrillation treatment is a catheter ablation. In typical catheter ablation procedure, triggers in pulmonary veins are addressed with a pulmonary vein isolation- offering a high long-term success rate in patients with paroxysmal atrial fibrillation. However, the same cannot be said for persistent and longstanding persistent atrial fibrillation. Studies have shown that efficiency of catheter ablation for persistent and longstanding persistent atrial fibrillation, including multiple procedures per patient, ranges around 50 %. It is postulated that extrapulmonary vein triggers, such as foci located in the posterior wall of the left atrium, play an important role in initiating and maintaining persistent and longstanding persistent atrial fibrillation. In the past, to address this issue, a convergent procedure was developed. In convergent procedure an epicardial ablation of posterior wall is performed through a subxyphoid window. Next, an endocardial ablation with an ablation catheter is performed to isolate pulmonary veins. Because the epicardial lesions are applied in the opposite direction and not towards the esophagus, ablation of posterior wall can safely be performed. The procedure offers a high long-term success rate (85%) in patients with persistent and longstanding persistent atrial fibrillation. However, due to higher associated invasiveness, the convergent procedure carries a higher risk of complications compared with catheter ablation (4 % vs 9 %). With advancements in ablation catheter technology, such as continuous force measurement at the tip of the catheter, the depth and volume of the lesion can be estimated. This information greatly increases the reliability of lesion formation. The operator can thus effectively apply lesions to the posterior wall of the left atrium more safely in regards to the collateral damage to the esophagus. The objectives of the study are: - To compare procedural, safety and efficiency profile of convergent procedure with catheter ablation procedure, both targeting pulmonary veins triggers and triggers located in the posterior wall of the left atrium. - To compare long-term success rate of convergent procedure with catheter ablation procedure, both targeting pulmonary veins triggers and triggers located in the posterior wall of the left atrium.

NCT ID: NCT04086069 Withdrawn - Clinical trials for Lower Limb Amputation

Sit-to-stand Trainer in Patients After Lower Limb Amputation

STSTrainer
Start date: February 6, 2019
Phase: N/A
Study type: Interventional

The study will include rehabilitation inpatients after unilateral lower limb amputation who are candidates for walking with a prosthesis. Those in the experimental group will receive training using a sit-to-stand trainer device in addition to standard training of standing-up with the help of a physiotherapist. Those in the control group will only receive the standard training. The effects of the rehabilitation programme will be assessed using the 30-Second Chair Stand Test before the start of the training and after 10 days of training. For the first five patients from each group who will be able to stand up with the use of hands, detailed kinesiological analysis of standing-up pattern will be performed.

NCT ID: NCT04043091 Withdrawn - Clinical trials for Coronary Artery Disease

Coronary Angiography in Critically Ill Patients With Type II Myocardial Infarction

Start date: September 2019
Phase: N/A
Study type: Interventional

Study type: prospective cohort and randomized trial. Duration: estimated 2 years. Indications: Type II myocardial infarction in critically ill patients. Purpose: 1. To recognise the incidence of type I myocardial infarction (MI) in patients with suspected type II MI. 2. Determining the safety of early coronary angiography in this population. 3. Assessment of the effect of percutaneous coronary revascularization in critically ill patients with stable obstructive coronary disease and type II MI. Hypotheses: 1. Obstructive coronary artery disease suitable for percutaneous revascularization is present in majority of patients with type II MI. 2. Type I MI (acute coronary artery thrombosis) is present in some patients and not recognised. 3. Echocardiogram and a 12-lead electrocardiogram are not reliable in predicting coronary artery disease. 4. Urgent invasive diagnostic is safe in patients with type II MI. 5. Percutaneous revascularization (if indicated) reduces the size of myocardial necrosis in patients with type II MI. Objectives: - Primary endpoint: to demonstrate that percutaneous coronary intervention (PCI) in the group with obstructive coronary disease reduces the size of MI. - Secondary endpoints: improved cardiac function after revascularization, shorter hospitalization, reduced mortality. - Safety objective: renal function, bleeding complications. Population: 140 patients with type II MI over 18 years of age with no evidence of active bleeding. Inclusion criteria: - age> 18 years - High sensitive troponin I > 40 ng / L for women and > 58ng / L for men - Critical illness (at least one vital organ support) - Imaging signs (electrocardiogram or ultrasound) signs of myocardial ischemia Exclusion criteria: - active bleeding - terminal illness Monitoring of patients: during hospitalization, 30 days after discharge, 6 months after discharge. Performance check: - PCI success (% of "thrombolysis in myocardial infarction" flow 3) - the size of MI (troponin area under the curve) - left ventricular ejection fraction - hospital stay - 30 day survival Safety Check: - monitoring of renal function - monitoring of bleeding complications - monitoring of allergic reactions to contrast and medication Patient Consent: written informed consent for inclusion in the study in conscious population.

NCT ID: NCT02645201 Withdrawn - Clinical trials for Helicobacter Infections

The Effect of Probiotic Combination on Helicobacter Pylori Infection in Children

Gastrus
Start date: January 2016
Phase: N/A
Study type: Interventional

The combination of two Lactubacillus reuteri strains, ATC 55730 and ATCC PTA 6457 are marketed as GASTRUS® and has been proposed as better option in increasing Helicobacter pylori eradication rate compared to the single strain ATC 55730, due to additional anti-inflammatory properties of the second strain. Objectives of the study are to determine whether adding probiotic combination (GASTRUS®) to an anti- Helicobacter pylori regimen decreases adverse events and increases the eradication rate of Helicobacter pylori in the pediatric population infected with Helicobacter pylori bacteria.
