NCT ID: NCT03606330 Not yet recruiting - Clinical trials for Acute Coronary Syndrome

Systemic, Pancoronary and Local Coronary Vulnerability

Start date: August 1, 2018
Study type: Observational

• The aim of the VIP study is to investigate the impact of vulnerability markers (inflammatory serum biomarkers for systemic vulnerability, coronary shear stress and vulnerability mapping for pancoronary vulnerability, and imaging-based plaque features for systemic vulnerability) on the rate of major adverse cardiovascular events caused by progression of the non-culprit lesion in patients with acute ST or non-ST segment elevation myocardial infarction who undergo revascularization of the culprit lesion during the acute event. Furthermore, the study will evaluate the rate of progression of non-culprit lesions towards a higher degree of vulnerability, based on coronary computed tomography angiographic assessment at 1 year after enrollment.

NCT ID: NCT03552432 Recruiting - Clinical trials for Coronary Artery Disease

The Efficacy of Alirocumab for Thin-cap fIbroatheroma in Patients With Coronary Artery Disease Estimated by Optical Coherence Tomography

Start date: September 26, 2017
Phase: Phase 4
Study type: Interventional

the purpose of this study is to show that alirocumab with statin therapy have a s tronger stabilizing effect on vulnerable plaque in coronary artery disease than statin alone administration

NCT ID: NCT03466255 Recruiting - Clinical trials for Myocardial Infarction

Early Detection of Cardiovascular Disease

Start date: December 6, 2016
Phase: N/A
Study type: Observational

The investigators plan to evaluate the correlation between carotid plaque enhancement on Contrast-enhanced ultrasound (CEUS), significant coronary artery disease (CAD), and cardiovascular (CV) outcomes in a systematic manner. The investigators hypothesize that increased levels of CEUS-detected vulnerable carotid plaque will be predictive of CV risk determined by angiography and future cardiovascular events.

NCT ID: NCT03414840 Recruiting - Clinical trials for Coronary Artery Disease

Assessment of Change in Atherosclerotic Plaque by Serial CCTA

Start date: April 1, 2018
Study type: Observational

Assessment of Change in AtheROSclerotic Plaque by Serial CCTA (ACROSS) is designed as a prospective observational study which aim is to demonstrate the effect of statins on coronary atherosclerosis, assessed by quantitative analysis of CCTA.

NCT ID: NCT03395041 Recruiting - Atherosclerosis Clinical Trials

Periodontal Disease, Inflammation and Acute Coronary Syndromes

Start date: May 15, 2018
Study type: Observational

Recent studies have shown that the systemic inflammation caused by periodontal disease (PD) can determine important changes in the coronary arteries, favoring atherosclerosis progression and development of acute coronary syndromes (ACS). The aim of ATHERODENT study is to assess the interrelation between PD, inflammation and progression of coronary atherosclerosis in patients with ACS. Material and methods: This case-control observational study will enroll 100 patients (group 1 - ACS and associated PD, and group 2 -ACS and no PD), in whom the following data will be collected: (1) demographic and clinical data, (2) cardiovascular risk factors, (3) full characterization of PD markers, (4) systemic inflammatory biomarkers, (5) imaging biomarkers derived from transthoracic echocardiography, computed tomography, coronary angiography, optical coherence tomography and intravascular ultrasound, and (6) assessment of the presence of specific oral bacteria in samples of coronary plaques collected by coronary atherectomy, which will be performed during percutaneous revascularization interventions, when indicated in selected cases, in the atherectomy sub-study. The follow-up will be performed at 1, 3, 6, 12, 15, 18 and 24 months. The primary endpoint of the study will be represented by the rate of major adverse cardiovascular events (MACE rates) in PD vs non-PD patients and in correlation with: (1) the level of systemic inflammation triggered by PD and/or by ACS at baseline; (2) the vulnerability degree of atheromatous plaques in the coronary tree (culprit and non-culprit lesions); and (3) the presence and burden of oral bacteria in atheromatous plaques. Secondary endpoints will be represented by: (1) the rate of progression of vulnerability degree of non-culprit coronary plaques; (2) the rate of progression of atheromatous burden and calcium scoring of the coronary tree; and (3) the rate of occurrence of left ventricular remodeling and postinfarction heart failure.

NCT ID: NCT03391908 Recruiting - Atherosclerosis Clinical Trials

Multiomics and Imaging-based Assessment of Vulnerable Coronary Plaques in Acute Coronary Syndromes

Start date: April 1, 2018
Study type: Observational

The aim of Multiplaque clinical study is to assess the vulnerability degree of the atheromatous plaques, before and after a myocardial infarction (MI), based on multiomics analysis, associated with invasive and non-invasive data. In this study, a multi-parametric model for risk prediction will be developed, for evaluation of the risk that is associated with the vulnerable coronary plaques in patients that have suffered an acute coronary syndrome. In the study, evaluation of the imaging characteristics of these coronary plaques will be performed with the use of CT, OCT, IVUS and invasive angiography. We will study the correlation between plaque evolution and (1) the degree of vulnerability at baseline, (2) multiomics profile of the patients and (3) clinical evolution during follow-up. Also, new techniques for evaluation of the functional significance of coronary stenoses will be studied and validated, such as calculation of the fractional flow reserve or determination of shear stress in areas that are localized within the near vicinity of the vulnerable coronary plaques.

NCT ID: NCT03382249 Not yet recruiting - Clinical trials for Carotid Atherosclerosis

Sonodynamic Therapy Manipulates Atherosclerosis Regression Trial on Patients With Carotid Atherosclerotic Plaques

Start date: June 10, 2018
Phase: Phase 1/Phase 2
Study type: Interventional

Sonodynamic therapy (SDT) is a new treatment for carotid atherosclerotic plaque. The aim of this study is to assess the safety and efficacy of this technique.

NCT ID: NCT03381222 Not yet recruiting - Clinical trials for Ascending Aortic Atheromatous Plaque

Incidence of Ascending Aortic Atheromatous

Start date: July 1, 2018
Phase: N/A
Study type: Observational [Patient Registry]

Background Incidence of perioperative stroke In cardiac surgery is 2.6-5.2%. Ascending aortic atheromatous plaque and stroke are strongly associated. Propose of study To determine incidence of ascending aortic atheroma in Thai people To identify risk factors which associated with ascending aortic atheroma Methodology After received standard general anesthesia and start sternotomy. Epiaortic scan will be performed by surgeon use L15-7i Phillips® ultrasound probe cover with sterile cover. Five standard epiaortic views will be collected. Epiaortic clips will be review and determine about atheroma by two qualified echocardiographers. Atheroma more than third grade will defined to significant. Potential risk factors of atheroma will be gather from medical record To assess the relationship between risk factors and atheroma a univariate analysis was performed using an unpaired t-test and a Chi-square test. For higher accuracy regarding the impact of single risk factors, a multiple logistic regression analysis was also performed.

Phase: N/A
Study type: Observational

This proposed follow-up study aims to recruit participants from the original BioImage cohort for a one-time follow-up examination. The repeat ultrasound scan of the carotid arteries will provide information on the natural history of carotid atherosclerosis and factors that contribute to plaque progression. Renewal of the HIPAA authorization will also be sought for 5 years to continue to monitor claims and other information for major cardiovascular events, other outcomes and healthcare utilization.
