ISCHEMIA-EXTEND (Extended Follow-up)

Start date: July 2012
Phase:
Study type: Observational

The International Study of Comparative Health Effectiveness with Medical and Invasive Approaches (ISCHEMIA) Extended Follow-up (ISCHEMIA-EXTEND) is the long-term follow-up of randomized, surviving participants in ISCHEMIA. ISCHEMIA was an NHLBI-supported trial that randomized 5,179 participants with stable ischemic heart disease to two different management strategies: 1) an initial invasive strategy (INV) of cardiac catheterization and revascularization when feasible plus guideline-directed medical therapy (GDMT), or 2) an initial conservative strategy (CON) of GDMT. The trial did not demonstrate a reduction in the primary endpoint with an initial invasive strategy. There was an excess of procedural myocardial infarction (MI) and a reduction in spontaneous MI in the INV group. Prior evidence suggests that spontaneous MI carries a higher risk of subsequent death than procedural MI. There was a late separation in the cardiovascular (CV) mortality curves over a median of 3.2 years follow-up in ISCHEMIA. The MI incidence curves crossed at approximately 2 years. However, during the trial follow-up phase there were excess non-CV deaths in the invasive strategy. Therefore, it is imperative to ascertain long-term vital status to provide patients and clinicians with robust evidence on whether there are differences between management strategies and to increase precision around the treatment effect estimates for risk of all-cause, CV and non-CV death over the long-term. Overarching Goal: To assess the effect of an initial invasive strategy on long-term all-cause, CV and non-CV mortality compared with an initial conservative strategy in SIHD patients with at least moderate ischemia on stress testing, over 10 years median follow-up.

NCT ID: NCT04888260 Completed - Clinical trials for Coronary Artery Disease

Plasma Mannose Associated Parameter Levels in Nondiabetic Coronary Artery Disease

Start date: January 10, 2018
Phase:
Study type: Observational

Aims: Nondiabetic patients have been studied to determine whether modest elevations in plasma mannose levels may be associated with a greater incidence of coronary artery disease (CAD). Methods: The plasma mannose, lipids (triglyceride, LDL, HDL, LDL, VLDL) and LDH levels were successfully will be evaluated with respect to subsequent coronary artery disease using records 120 nondiabetic patients and 120 healthy volunteers. CAD was identified from myocardial infarction and new diagnoses of angina. The associations between mannose levels and serum lipid parameters will be investigated.

Drug-eluting Balloon Versus Drug-eluting Stent for High Bleeding Risk Angioplasty

DEBORA
Start date: April 20, 2021
Phase: N/A
Study type: Interventional

Randomized, single-blind, single-center, non-inferiority clinical trial to compare target lesion failure (TLF) at 12 months in high bleeding risk patients undergoing elective coronary percutaneous intervention comparing limus-eluting balloon vs. limus-eluting stents.

Correlation of FFR and iFR With Cardiac PET Perfusion in Patients With Severe Aortic Valve Stenosis

TAVI PET
Start date: June 1, 2021
Phase:
Study type: Observational

Aortic valve stenosis (AS) affects 2-7% of persons > 65 years, symptoms include: angina and dyspnea, dizziness and syncope. Coincidence of coronary artery disease (CAD), also presenting with angina and dyspnea, in patients with AS between 40 - 65% . Angina in AS caused by significant reduction of coronary flow reserve (CFR). CFR is the ratio of maximal flow increase in the coronary vessel bed during maximal hyperaemia (medically or exercise induced). FFR (fractional flow reserve) use in patients with AS potentially invalid due to dysfunctional CFR leading to potential undertreatment of CAD in these patients.CFR disturbance in AS mainly due to myocardial overload causing concentric hypertrophy, increased oxygen consumption and neurohormonal activation leading to increased vascular resistance. Current studies are investigating the validity of FFR and iFR in AS patients. Recent data demonstrate very good correlation between FFR and iFR derived values to PET myocardial perfusion imaging values in patients with no evidence of AS. Our study aims to investigate the diagnostic performance of FFR and iFR in intermediate-grade coronary stenosis in patients with severe aortic valve disease and correlate FFR- and iFR derived values with those extracted from PET-perfusion Imaging.

DEFINing the PrEvalence and Characteristics of Coronary Artery Disease Among Patients With TYPE 2 Myocardial Infarction Using CT-FFR

DEFINE TYPE2MI
Start date: April 11, 2021
Phase:
Study type: Observational

The primary objectives of this study include: - determine the prevalence of coronary artery disease among patients with type 2 myocardial infarction - determine the prevalence of hemodynamically significant stenosis among patients with type 2 myocardial infarction The investigators hypothesize that patients with type 2 myocardial infarction will have a high burden of coronary artery plaque and a high prevalence of obstructive coronary artery disease with hemodynamic significance.

Effectiveness of TechCR Among CHD Patients

TechCR
Start date: February 26, 2021
Phase: N/A
Study type: Interventional

During this ongoing pandemic, there is a crucial need for innovative approaches to deliver CR programmes other than frequent face-to-face sessions at the centre-based CR to reduce the number of times people come close in contact with others or gathering in large groups. This is a single setting, 2-arm parallel randomised clinical trial which aims to examine the effects of technology-assisted interventions in hybrid cardiac rehabilitation (TecHCR) among the coronary heart disease patients. Eligible participants will be randomly assigned into either intervention group (IG) or control group (CG) in 1:1 ratio using the computerised permuted blocks, alternating block sizes of 4 or 6. All participants will be followed up for three months and six months with data collection at baseline, (T0), three-month (T1) and six-month (T2) time points.

Phase: N/A
Study type: Interventional

This study aims to examine the effects of an internet-based cardica rehabilitation enhancement (i-CARE) programme for coronary artery disease (CAD) patients on self-care behaviour, biomarkers, physiological, anthropometric parameters, clinical outcomes and self-reported health outcomes and to understand why and how i-CARE influences patients' health behaviours.
