NCT ID: NCT03561389 Recruiting - Clinical trials for ST Segment Elevation Myocardial Infarction

ISTANTANEOUS WAVE-FREE RATIO OF NONCULPRIT LESIONS IN ST- SEGMENT ELEVATION MYOCARDIAL INFARCTION AND LONG-TERM OUTCOME

WAVE
Start date: May 1, 2018
Phase:
Study type: Observational

Functional assessment of non-culprit lesions during percutaneous coronary intervention (PCI) in patients with acute coronary syndrome could improve risk stratification and long-term prognosis. It was previously demonstrated the diagnostic accuracy of instantaneous wave-free ratio (iFR) in functional assessment of non-culprit lesions in multivessel patients with ST-segment elevation myocardial infarction (STEMI), also highlighting the intralesional reproducibility of both fractional flow reserve (FFR) and iFR between baseline and staged. In this study the investigators aimed to verify the clinical impact on long-term outcome of iFR assessment in the acute multivessel setting.

The Pre-hospital Evaluation of Sensitive Troponin (PRESTO) Study

Start date: September 1, 2018
Phase:
Study type: Observational

The aim of the study is to assess whether a decision aid that is currently used in hospitals across Greater Manchester to determine how likely it is that a patient has a serious heart problem is still accurate in the pre-hospital environment.

NCT ID: NCT03552575 Not yet recruiting - Heart Failure Clinical Trials

The Effects of Sacubitril/Valsartan Compared to Valsartan on LV Remodelling in Asymptomatic LV Systolic Dysfunction After MI

RECOVER-LV
Start date: July 1, 2018
Phase: Phase 3
Study type: Interventional

Prior to reperfusion therapy, the major therapeutic breakthrough in myocardial infarction was the demonstration that ACE inhibitors or ARBs, given to prevent adverse "remodelling" (progressive dilatation and decline in systolic function) in high risk patients, reduced the likelihood of developing heart failure and the risk of death. The neurohumoral systems which are activated in patients after myocardial infarction (and in heart failure) are not all harmful and some endogenous systems may be protective. The best recognised of these is the natriuretic peptide system. A- and B-type natriuretic peptides are secreted by the heart when it is stressed and these peptides promote vasodilation (reducing left ventricular wall stress), stimulate renal sodium and water excretion (i.e. antagonising the retention of salt and water characterising heart failure) and inhibit pathological growth i.e. hypertrophy and fibrosis (key components of the adverse left ventricular remodelling that occurs after infarction and in heart failure).The augmentation of plasma levels of endogenous natriuretic peptides can be achieved through inhibition of neutral endopeptidase, also known as neprilysin (NEP), which is responsible for the breakdown of natriuretic peptides. Recently, the addition of neprilysin inhibition to blockade of the RAAS (using sacubitril/valsartan), compared with RAAS blockade alone, reduced the risk of heart failure hospitalisation and death in patients with HF-REF. These exciting findings may lead to a new approach to the treatment of heart failure, with an angiotensin receptor neprilysin inhibitor (ARNI) replacing an ACE inhibitor as one of the fundamental treatments for this condition. We believe that the same approach may be beneficial in highrisk survivors of myocardial infarction. Recently, sacubitril/valsartan was shown to ameliorate adverse left ventricular remodelling in an experimental model of acute myocardial infarction. The objective of the present proposal is to gather "proof-ofconcept", mechanistic, evidence in humans to support adoption of this new approach in patients at high risk after myocardial infarction as a result of residual left ventricular systolic dysfunction.

DAPT-SHOCK-AMI
Start date: June 2018

NCT ID: NCT03539133 Recruiting - Clinical trials for ST-segment Elevation Myocardial Infarction (STEMI)

ST-segment Elevation Myocardial Infarction Clinical Pathway

Start date: October 18, 2017
Phase:
Study type: Observational

Despite progress in pre-hospital care, ambulance logistics, pharmacotherapy and PPCI techniques, ST-segment elevation myocardial infarction (STEMI) continues to confer a substantial burden of morbidity and mortality. Within the STEMI population, there is a spectrum of higher and lower risk patients. The aim of this registry is to collect prospectively and systematically clinical research data from STEMI patients. This registry is an open-end observational study to identify master switches in myocardial ischemia.

Routine Ultrasound Guidance for Vascular Access for Cardiac Procedures

UNIVERSAL
Start date: June 30, 2018
Phase: N/A
Study type: Interventional

A randomized, controlled trial to determine whether the use of ultrasound guidance for vascular access during coronary angiography or percutaneous coronary intervention (PCI) will reduce the rates of major vascular complications.

NCT ID: NCT03534817 Recruiting - Clinical trials for Myocardial Infarction

Early Versus Standard Access Cardiac Rehabilitation to Counter Ventricular Remodeling Post-MI (EVADE)

EVADE
Start date: January 8, 2018
Phase: N/A
Study type: Interventional

BACKGROUND: Cardiac rehabilitation (CR) is an outpatient chronic disease management program delivering secondary prevention, which is proven to reduce morbidity and mortality. The Canadian Cardiovascular Society Access to Care working group recommends patients access CR "preferably" within 2-7 days following percutaneous intervention for myocardial infarction (MI), but that 30-60 days is "acceptable". Despite these benchmarks, in practice patients access CR up to 90 days post-treatment in Canada. This is disconcerting given the detrimental impacts of delayed access to CR. These include ventricular remodeling (i.e., ventricular enlargement and reduced pump function), lower CR use, less post-CR exercise, among others. Accordingly, EVADE will be the first randomized controlled trial (RCT) to test the effects of early access CR (1-week post-discharge to first CR visit) compared to standard access CR (7-weeks post-discharge to first CR visit) in ameliorating these concerns. AIMS & HYPOTHESIS: The primary aim is to compare ventricular remodeling as defined by the change in end-systolic volume at 1-year in participants randomized to early versus standard access CR. The secondary aims are: (1) to compare post-CR exercise adherence by accelerometry, exercise capacity by 6-minute walk test distance, and health-related quality of life (HRQL) at 1-year in participants randomized to early versus standard access CR; (2) to compare CR program session attendance in participants randomized to early versus standard access CR; and (3) to assess biomarkers of ventricular remodeling in participants randomized to early versus standard access CR. The final aims are to explore more immediate health benefits associated with early versus standard access CR. Accordingly, at 6 months following hospital discharge the investigators will measure end-systolic volume, exercise adherence, exercise capacity, biomarkers of ventricular remodeling, and HRQL. The investigators will also explore hospitalization for any cause of death at 1 year in order to inform future research. The overall hypothesis is that early access CR will be associated with less ventricular remodeling, increased CR attendance and post-CR exercise adherence, increased exercise capacity, and greater HRQL. DESIGN: EVADE will be a two-centre, 2 parallel-arm, single-blinded RCT. Participants will be recruited through coronary care units following treatment for MI from the Royal University Hospital in Saskatoon, Saskatchewan and the University of Alberta Hospital in Edmonton. The University of Alberta Research Electronic Data Capture (REDCap) online database will randomize (1:1) participants (allocation concealed). A total of 60 participants will be enrolled: 30 participants will each be allocated to early access and standard access CR. IMPACT: In the first prospective multicentre trial of its kind, EVADE will test an innovative post-MI rehabilitation strategy that has the potential to demonstrate the superior benefits of early access CR for attenuating ventricular remodeling, and increasing CR attendance, post-CR exercise adherence, exercise capacity, and HRQL. The results from EVADE would encourage the Canadian CR community to consider early access CR to further enhance readily available and existing CR programs. The knowledge gained from EVADE will inform clinical decision-making practices, influence future CR guidelines and policy, and will contribute to the ongoing goal of improving efficiency and effectiveness of the Canadian health care system.
