Active clinical trials for "Infarction"

Patients with anterior wall AMI treated by PCI will undergo, after successful revascularization of the infarct artery, measurement of the left ventricular pressure, and femoral angiogram. Patients with elevated LV pressure and adequate femoral access will be randomized to standard pharmacological treatment of AMI vs. mechanical unloading by Impella-CP (on top of the standard treatment) for 36-48 hours. LV unloading will be guided by measurement of PCWP by Swan-Ganz catheter. On the day 4-7, and at 3 months after the AMI, the patients will undergo SPECT and 3D-echocardiography to assess ventricular remodeling and extent of the post-infarct scar. The patients will be followed for at least 12 months for the occurrence of heart failure and adverse cardiovascular events. The study will test the hypothesis, whether the LV mechanical unloading after PCI will attenuate post-infarct scar and cardiac remodeling.

The purpose of the DYNAMITE trial (Dynamic CT stress myocardial perfusion, CT fractional flow reserve (FFR-CT) and coronary CT angiography for optimized treatment strategy in patients with chest pain syndromes) is to determine the ability of combined anatomical and functional cardiac CT imaging to improve morbidity and mortality in patients with suspected or known ischemic heart disease.

The study aims to evaluate a modified antiplatelet therapy associated with Firehawk low-dose rapamycin DES in acute myocardial infarction patients treated with complete revascularization strategy. The modified antiplatelet therapy consists of a reduced duration of Dual Antiplatelet Therapy post procedure (ie. 1 month duration) followed by P2Y12 inhibitor monotherapy for the next 11 months. It is hypothesized that in the setting of clinically stable, low to moderate complexity acute Myocardial Infarction patients, a modern approach combining a stent with high biocompatibility feature, complete revascularization strategy and modified antiplatelet therapy may be associated with similar outcomes, or even a significant benefit compared with guidelines-recommended 12-month DAPT. This benefit could be driven by a reduced risk in significant bleeding events, while keeping a comparable protection against ischemic risk. Enrolled subjects will be randomized in a 1:1 ratio to either cessation of aspirin at 1 months, either continuation of DAPT. Selection of the P2Y12 inhibitor agent is left to investigator judgment but has to be in line with the current ESC guidelines. Subjects treated with the Firehawk or Firehawk Liberty coronary stent will be included in this study.

This study is a prospective, open-label, two-arm, randomized multicenter trial to identify whether immediate multi-vessel PCI would be better in clinical outcomes compared with culprit lesion-only PCI for AMI and multi-vessel disease with an advanced form of CS patients who require veno-arterial extracorporeal membrane oxygenator (VA-ECMO).

Patients with heart attack or heart injury are tested (angiogram) for blockages in their arteries. Many patients develop heart problems caused by damage to small (microvascular) blood vessels. These issues are also relevant to patients with coronarvirus-19 disease (COVID-19). Eplerenone reduces blood vessel injury and is used to treat heart failure. Aim: to test the use of eplerenone in patients with heart attack/heart injury who have small vessel disease, including patients with COVID-19 Patients referred to the Golden Jubilee hospital with a suspected heart attack heart / injury will be invited to participate into a registry-based clinical trial. Screening, enrolment and verbal, informed consent will be obtained during the angiogram then written consent on the ward. Small vessel disease will be assessed using a 'diagnostic' guidewire during the standard angiogram. People with small vessel problems will be allocated to a clinical trial of usual care or eplerenone. Coronary microvascular dysfunction is defined as an index of microvascular resistance ≥25. Coronary flow reserve (CFR abnormal <2.0) and resistance reserve ratio (RRR abnormal <2.0), measured simultaneously with IMR, are predefined parameters of interest. Patients will be allocated into one of the 3 groups: Group 1: Patients without coronary microvascular dysfunction. No eplerenone Group 2: Patient with coronary microvascular dysfunction. Usual care, no eplerenone. Group 3: Small vessels abnormal. Eplerenone tablets. The primary outcome for the trial will be reduced heart injury (biomarkers) in patients with microvascular disease. We will also test heart function (MRI scan) at enrolment and at six months. All patients (Groups 1, 2 and 3) will have an angiogram. Standard blood tests will be collected during the hospital stay, and then again at 1 and 6 months. Other outcomes include questionnaires (health status). We will gather information on longer-term health outcomes (hospitalisation, death) using confidential electronic record linkage. We will ask for permission to store blood samples for future research. The research will improve scientific knowledge about eplerenone therapy in this patient group. The study will create a repository of clinical samples and images which will provide vital data for studies of COVID-19.

This prospective, multicenter, non-randomized, single arm, objective performance goal (OPG) study is designed to evaluate clinical outcomes after complete revascularization by PCI and imaging guidance (OCT) in patients with multivessel coronary artery disease including left anterior descending (LAD) presenting with stable angina, or documented silent ischemia, or non-ST segment elevation acute coronary syndrome (NSTE-ACS).

The aim of our study is to evaluate if the use of a precision-medicine approach with a specific therapy tailored on the underlying pathogenic mechanism will improve the quality-of-life in MINOCA patients. The investigators further aim at investigating wherever a precision-medicine approach will improve the prognosis, healthcare related costs, and if that a different profile of plasma biomarkers and microRNAs may serve as diagnostic tools for detecting specific causes of MINOCA and to assess response to therapy. Finally, beyond its pivotal role in differential diagnosis, the investigators hypothesize that cardiac magnetic resonance (CMR) may provide a morphological and functional cardiac characterization as well as help in the prognostic stratification.

Patients post acute myocardial infarction (AMI) have a high risk of mortality but the use of an implantable defibrillator in the early aftermath of an AMI has not been shown to improve patients' survival. The VEST trial recently demonstrated an improved overall survival in post AMI patients with the use of a wearable defibrillator. The same improvement was not demonstrated for the risk of sudden cardiac death. Monitoring patients after AMI using an implantable cardiac monitor (ICM) may document findings that can impact patient management and eventually improve their outcomes. We are therefore conducting the AID MI trial to examine the impact of ICM on patient management in the post AMI setting.

The purpose of this study is to assess whether hemodynamic support with an Impella-based treatment strategy initiated prior to percutaneous coronary intervention (PCI) in patients with ST-Segment Elevation Myocardial Infarction (STEMI)-Cardiogenic Shock (CS) improves survival and functional outcomes compared to a non-Impella-based treatment strategy.

An investigator-initiated, randomized, multicenter, two-arm, open-label study of consecutive patients presenting with STEMI and MVD Objectives: The present study aimed to investigate the difference in all-cause mortality after in-hospital staged PCI versus out-hospital staged PCI for ST-segment elevated myocardial infarction （STEMI）patients with multi-vessel Disease（MVD） Background: In primary percutaneous coronary intervention for STEMI with MVD, complete revascularization has proved to reduce the risk of cardiovascular death and myocardial infarction. However, a strategy of nonculprit-vessel PCI with the goal of complete revascularization still not to be confirmed. Compare with in-hospital staged PCI, out-hospital PCI as a strategy of nonculprit-vessel PCI for STEMI patients with MVD might have be beneficial results.
