What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study looks at whether a follow-up CT scan of the heart's arteries (coronary CT angiography) one year after stent placement can reduce major heart problems like heart attacks or death compared to usual care. It will enroll 3,500 high-risk patients who have had stents placed for blocked arteries. The goal is to see if early detection of new blockages via CT leads to better outcomes.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Coronary CT angiography (CCTA) imaging test
What this could lead to
If successful, this could show that routine CT scans after stent placement help catch problems early and reduce heart attacks or deaths.
What could go wrong
This is an observational comparison, not a treatment test. The results may not change current practice if CCTA leads to unnecessary procedures or anxiety.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 3,500 people

The number the study aims to enrol. It can still change while the study runs.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: ① Patients aged 19 years old ② Patients who underwent successful PCI with one or more contemporary drug-eluting stents (stent diameter ≥3mm) or drug-coated balloons. ③ Patients must have at least one of the following criteria of complex coronary artery lesions or high-risk clinical characteristics: A. Complex coronary artery lesions: i. True bifurcation lesion (Medina 1,1,1/1,0,1/0,1,1) with side branch ≥2.5mm size ii. Chronic total occlusion (≥3 months) as target lesion iii. PCI for unprotected left main (LM) disease (LM ostium, body, distal LM bifurcation including non-true bifurcation) iv. Long coronary lesions (used stents or drug-coated balloons ≥38 mm in length) v. Multi-vessel PCI (≥2 major epicardial coronary arteries treated at one PCI session) vi. Multiple devices needed (≥3 more stents or drug-coated balloons per patient) vii. In-stent restenosis lesion as target lesion viii. Severely calcified lesion (encircling calcium in angiography) ix. Left anterior descending (LAD), left circumflex artery (LCX), and right coronary artery (RCA) ostial lesion B. High-risk clinical characteristics: i. Acute myocardial infarction (ST-elevation myocardial infarction \[MI\] or non-ST-elevation MI) with or without cardiogenic shock (SCAI Classification ≥C) at presentation ii. Diabetes mellitus which requires medical treatment (oral hypoglycemic agents or insulin) iii. End-stage renal disease under dialysis iv. Combined vascular disease other than coronary artery disease 1. Peripheral artery occlusive disease which is defined as A. Previous aorto-femoral bypass surgery, limb bypass surgery, or percutaneous transluminal angioplasty revascularization of the iliac, or infra-inguinal arteries, or B. Previous limb or foot amputation for arterial vascular disease, or C. History of intermittent claudication and one or more of the following: 1) An ankle/arm blood pressure (BP) ratio \< 0.90, or 2) Significant peripheral artery stenosis (≥50%) documented by angiography, or by duplex ultrasound, or D. Previous carotid revascularization or asymptomatic carotid artery stenosis ≥50% as diagnosed by duplex ultrasound or angiography. 2. Thoracoabdominal aortic disease which is defined as A. Documented thoracoabdominal aortic aneurysm by duplex ultrasound, angiography, or computed tomography angiography B. Previous endovascular or surgical treatment for thoracoabdominal aortic aneurysm ④ Subject who can verbally confirm understandings of risks, benefits and surveillance strategy alternatives of receiving CCTA and he/she or his/her legally authorized representative provides written informed consent prior to any study related procedure. Exclusion Criteria: ① Advanced chronic kidney disease (Creatinine clearance \<30 ml/min/1.73 m2) not on dialysis * Known true anaphylaxis to contrast medium (not allergic reaction but anaphylactic shock) * Pregnancy or breast feeding ④ Non-cardiac co-morbid conditions are present with life expectancy \<1 year or that may result in protocol non-compliance (per site investigator's medical judgment) ⑤ Unwillingness or inability to comply with the procedures described in this protocol.
