NCT ID: NCT03797651 Not yet recruiting - Clinical trials for Coronary Artery Disease, Acute Coronary Syndrome

Ticagrelor Monotherapy in PAtients Treated With New-generation Drug-eluting Stents for Acute Coronary Syndrome; T-PASS Trial

Start date: January 15, 2019
Phase: N/A
Study type: Interventional

We hypothesized that ticagrelor monotherapy might be enough to prevent thromboembolic events without aspirin after PCI in patients with acute coronary syndrome(ACS). Moreover, ticagrelor monotherapy will reduce bleeding risk compared to DAPT with aspirin plus ticagrelor. We will also evaluate 1-year safety and efficacy of Orsiro stent for patient with acute coronary syndrome. After confirmation of enrollment, patients will be randomized to continue standard treatment (aspirin plus ticagrelor) for 1 year or to stop aspirin after discharge or less than 1 month after PCI (ticagrelor monotherapy). Randomization will be stratified according to 1) the presence of diabetes and 2) ST elevation myocardial infarction (MI). Baseline clinical and angiographic characteristics, laboratory findings will be assessed at the time of randomization. All patients will provide informed consent on their own initiative.

NCT ID: NCT03793582 Recruiting - OSA Clinical Trials

Impact of OSA on Outcomes in Acute Coronary Syndrome

Start date: August 29, 2017
Study type: Observational

Elucidating the effects of obstructive sleep apnea (OSA) on cardiovascular outcomes in acute coronary syndrome (ACS) is crucial in risk assessments and therapeutic recommendations for affected individuals. Although large epidemiological studies have reported an association between OSA and both coronary heart disease (CHD) and heart failure (HF), its effect on outcomes in ACS is still unclear. In contrast to previous theories attributing causation to OSA, recent studies have hypothesized a cardio protective role of OSA. Repetitive hypoxemic episodes noted in OSA may lead to myocardial ischemic preconditioning, possibly by increasing coronary collateral vessel recruitment, conferring protection from acute coronary events. We propose a prospective, observational, single center study in patients presenting with ACS, including ST segment elevation (STEMI), non-ST segment elevation (NSTEMI) and unstable angina who undergo coronary revascularization to determine the impact of OSA on clinical outcomes after ACS. Adult patients above age 18 years who present with myocardial infarction are eligible. Recruited patients will undergo an overnight sleep study using a level III portable diagnostic device before hospital discharge. The sleep tracings will be analyzed and audited by a certified sleep physician. The patients will be divided into 2 groups based on apnea-hypopnea index (AHI): OSA (AHI ≥ 15) and non-OSA (AHI < 15) groups. The primary end points of this study were in-hospital, 30 day and 6 month major adverse cardiovascular events (MACE), defined as a composite endpoint of cardiovascular death, non-fatal MI, stroke and the need for unplanned repeat revascularization. Secondary endpoints include individual MACE outcomes of cardiovascular death, non-fatal MI, stroke, need for unplanned repeat revascularization, heart failure requiring hospitalization, and all-cause mortality.

Left Ventricular Dysfunction in Critically Ill Patients

Start date: August 20, 2018
Study type: Observational

Left ventricular dysfunction is common in the critically ill. The aim of this study is to assess the incidence and prognosis of left ventricular dysfunction in critically ill patients.

NCT ID: NCT03787797 Recruiting - Clinical trials for Acute Coronary Syndrome

Epicardial Adipose Tissue Thickness PredIcts Obstructive Coronary Artery Disease in Acute Coronary Syndrome Patients

Start date: December 6, 2018
Study type: Observational

Epicardial adipose tissue (EAT) is a visceral adipose tissue that surrounds the heart and the coronary arteries. It is metabolically active, secreting pro- and anti-inflammatory mediators and cytokines. With increasing EAT volume, inflammatory activity increasing, which suggests that EAT may locally influence atherosclerosis development in the coronary artery tree. The amount of EAT is associated with cardiovascular disease risk factors as well as presence and progression of subclinical atherosclerosis. Likewise, EAT volume is increased in patient with prevalent and incident coronary artery disease manifestation. In the setting of acute coronary syndrome, EAT was found to be associated with the TIMI risk score and Syntax II score. While CT imaging of the heart is the gold standard for EAT quantification, transthoracic echocardiography allows for a quick and reliable assessment of EAT thickness, as has been used in research studies and may qualify for routine EAT assessment in clinical routine.However, currently data on how quantification of EAT in clinical routine may impact patient management is lacking. We aim to investigate, whether quantification of EAT thickness via transthoracic echocardiography enables improved risk stratification in patients presenting with acute chest pain to the emergency department.

NCT ID: NCT03783351 Not yet recruiting - Clinical trials for Acute Coronary Syndrome

Genotyping GUided Antiplatelet theRapy in pAtieNts Treated With Drug Eluting stEnts (GUARANTEE)

Start date: February 2019
Phase: Phase 4
Study type: Interventional

The aim of this study is to assess the efficacy and safety of the CYP2C19 genotype guided antiplatelet treatment strategy, using clopidogrel in non-carriers of a CYP2C19*2 or *3 allele and ticagrelor in carriers of a CYP2C19*2 or *3 allele in patients treated with new generation drug eluting stents.

NCT ID: NCT03766789 Active, not recruiting - Clinical trials for Adherence, Medication

Use of a Smartphone Application to Increase Adherence to Medical Treatment in Patients With an Acute Coronary Syndrome.

Start date: June 12, 2018
Phase: N/A
Study type: Interventional

ADHERENCE is a randomized unicentric study that will be carried out from a monovalent center of cardiology of the Autonomous City of Buenos Aires. Patients will be randomized hospitalization for acute coronary syndromes (ACS) with and without ST segment elevation at the time of hospital discharge to receive access to a digital application for smartphones or receive written instructions regarding the taking of medication as prescribed by doctors . They will have a total follow-up period of 90 days, in which the adherence to medical treatment will be evaluated through a questionnaire validated for that purpose. The objective of the study is to demonstrate that the use of a digital platform for smartphones increases the adherence to medical treatment by 30% in relation to the group without intervention

NCT ID: NCT03760796 Recruiting - Clinical trials for Coronary Artery Disease

Myocardial Infarction, COmbined-device, Recovery Enhancement Study

Start date: October 1, 2017
Phase: N/A
Study type: Interventional

Unplanned readmissions after hospitalization for acute myocardial infarction (AMI) are among the leading causes of preventable morbidity, mortality, and healthcare costs. Digital health interventions (DHI) could be an effective tool in promoting self-management, adherence to guideline directed therapy, and cardiovascular risk reduction. A DHI developed at Johns Hopkins—the Corrie Health Digital Platform—includes the first cardiology Apple CareKit smartphone application, paired with an Apple Watch and iHealth Bluetooth-enabled blood pressure cuff. Corrie targets: (1) self-management of cardiac medications, (2) self-tracking of vital signs, (3) education about cardiovascular disease through articles and animated videos, and (4) care coordination that includes outpatient follow-up appointments. In this prospective study, STEMI or type 1 NSTEMI patients are being enrolled to use the Corrie Digital Health Platform beginning early during participants' hospital stay. Enrollment sites include Johns Hopkins Hospital, Johns Hopkins Bayview Medical Center, Massachusetts General Hospital, and Reading Hospital. The primary objective is to compare time to first readmission within 30 days post-discharge among patients with the Corrie Digital Health Platform to patients in the historical standard of care comparison group.

NCT ID: NCT03755700 Recruiting - Clinical trials for Coronary Artery Disease

Phase: Phase 3
Study type: Interventional

In a double-blinded randomized clinical trial, all patients undergoing coronary artery catheterization who will met our criteria, will be enrolled into three groups to receive either, vitamin e, n-acetylcysteine, or placebo. The aim of study will be to compare the superiority of vitamin e over n-acetylcysteine for the prevention of contrast-induced acute kidney injury (CIAKI).
