Active clinical trials for "Coronary Artery Disease"

The aims of the present study are to measure dynamic changes over time in the plasma level of SDF-1α in patients with confirmed diagnoses of AMI, AF and CHF and in so doing: Monitor the plasma level of SDF-1α at the diagnosis, during and after the long term treatment of AMI, AF and CHF. The SDF-1α level of patients is expected to decrease during treatment of the aforementioned conditions. Correlate the plasma level of SDF-1α in relation to clinical, biochemical characteristics of Acute Myocardial Infarction(AMI), Atrial Fibrillation(AF) and Congestive Heart Failure (CHF). In so doing, the investigators expect that SDF-1α will correlate with the severity of heart disease. Study the dynamic of SDF-1α pertaining to its property as prognostic indicator for the long term follow up risk of readmission and mortality of patients diagnosed with AMI, AF or CHF.

Olive extracts are considered to have antioxidant properties. The investigators will study the effect of olive extracts containing hydroxytyrosol on endothelial, cardiac and vascular function in patients with coronary artery disease .

Major cardiovascular surgery is associated with postoperative cognitive decline (POCD), with a deterioration in memory, attention and speed of information processing. A multifactorial pathophysiology is presumed but this study focuses on the role of (neuro)inflammation in the development of POCD after coronary artery bypass grafting (CABG) surgery.

To identify whether coronary artery disease (CAD) patients have fear of activity, and to assess the relationship between fear of activity and exercise capacity in CAD patients.

This prospective, multicenter, single-arm study aims to evaluate the safety, operability and practicability of the novel hybrid intravascular imaging system/catheter during the percutaneous transluminal coronary intervention.

Coronary artery disease and myocardial ischemia are among the leading causes of death and disability in the Westerns countries. Timely and accurate diagnosis of myocardial ischemia at the moment of symptom onset is crucial and often delayed. Portable smart medical devices nowadays offers the possibility of ubiquitous self multi-parametric monitoring. Application of such technologies to timely and autonomous detection of myocardial ischemia could be an effective strategy to an earlier and better treatment of symptomatic coronary artery disease. The primary objective is to assess the changes in recorded by the SmartCardia patch (respiratory rate, pulse transit time, heart rate and single ECG trace) during induced ischemia during elective coronary angioplasty procedures. The secondary objective is to asses whether myocardial ischemia can be predicted and quantified by changes in the parameters recorded by SmartCardia patch (respiratory rate, pulse transit time, heart rate and single ECG trace).

Insight Lifetech Intravascular Ultrasound Diagnostic System (referred to as Insight Lifetech IVUS system below),is a new high-speed and high-resolution device for clearly defining vessel architecture and plaque morphology, providing quantitative and qualitative assessment of coronary arteries. Besides, IVUS has already an established role in guidance and optimization of percutaneous coronary intervention. This study will compare the differences, if any, between the intravascular ultrasound(IVUS) results measured by the two different IVUS diagnostic systems.

DESIGN: Prospective, single-arm, multicenter, observational, prospective registry of the use of the RESOLUTE-ONYX™ zotarolimus-eluting stent in percutaneous coronary intervention in small vessels. Clinical follow-up at 1 month, 6 months and 1 year. OBJECTIVE: To evaluate the safety and efficacy of using RESOLUTE-ONYX zotarolimus-eluting stent in PCI in small vessels (diameter ≤2.5 mm). DISEASE UNDER STUDY: Adult patients with coronary artery disease (stable angina, silent ischemia or non-ST-segment elevation acute coronary syndrome) undergoing percutaneous coronary intervention on vessels with a diameter less than or equal to 2.5 mm. TOTAL NUMBER OF PATIENTS: Approximately 320 patients are expected to be included in the study.

The left distal radial approach (DRA) has been introduced as a feasible and safe alternative route of the radial artery. However, there is still lack of evidence for DRA regarding the feasibility, safety, effective time for hemostasis and hemostasis method. This prospective multicenter registry aimed to investigate the safety and efficacy of DRA for CAG and PCI.

Participants aged 80 years or over, who attend Castle Hill Hospital with either stable angina or an acute coronary syndrome will be invited to participate in the study. After induction into the study, these participants will be assessed for frailty and quality of life (QoL) using predetermined assessment tools. Quality of life (QoL) will be assessed using the standardised SF-12 questionnaire proforma. Frailty assessment will be based on the use of the Fried Frailty Phenotype criteria and the Edmonton Frailty Scale. Patients will be reassessed at 3,9 and 24 months for their clinical outcomes, repeat frailty assessment and quality of life.
