Study summary

The PREVENT-2 trial is to determine whether an initial invasive strategy-consisting of early coronary angiography (CAG) with intent for preventive percutaneous coronary intervention (PCI) in addition to optimal medical therapy (OMT)-reduces the incidence of the primary composite outcome of cardiac death, target-vessel myocardial infarction (MI), unplanned urgent revascularization, or hospitalization for unstable or progressive angina at 3 years, compared with an initial conservative strategy of optimal medical therapy (OMT) alone, in patients with high-risk vulnerable plaque identified by coronary computed tomography angiography (CCTA).

Terms in these criteria, in plain language(7)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

LVEF (left ventricular ejection fraction)

The share of blood the heart’s main pumping chamber (the left ventricle) pushes out with each beat, measured by an echocardiogram (heart ultrasound) or a MUGA scan. About 50–70% is normal.

NYHA class (heart failure)

The New York Heart Association’s four classes of how much heart failure limits physical activity.

I
No limits: ordinary activity causes no undue tiredness or breathlessness.
II
Slight limits: comfortable at rest, ordinary activity causes symptoms.
III
Marked limits: comfortable at rest, less than ordinary activity causes symptoms.
IV
Symptoms even at rest; any activity makes them worse.

Studies set their own limit — many outside heart failure leave out class III–IV, while heart failure studies may ask for a particular class. Check the class this study names.

GFR and eGFR (kidney filtering)

GFR (glomerular filtration rate) is how much blood the kidneys filter each minute. It is usually estimated from a blood test — eGFR, by formulas such as CKD-EPI or MDRD — and some studies ask for it to be measured directly instead. Usually given in mL/min/1.73 m².

Check the method, the units and the minimum the study states. A value of 90 or above is in the normal-or-high range, but kidney damage can show in other tests too.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

Life expectancy

The study doctor’s estimate of how long someone is likely to live. Criteria use it so that people can stay in the study long enough for it to answer its question.

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

Interventions

  • ProcedureInitial Invasive Strategy

    Invasive coronary angiography (CAG) within 30 days after randomization, with the intent to perform preventive percutaneous coronary intervention (PCI) in addition to optimal medical therapy (OMT). For further detailed assessment of vulnerable plaque lesions detected by coronary computed tomography angiography, the use of intracoronary imaging modalities (near-infrared spectroscopy, optical coherence tomography, or intravascular ultrasound) will be strongly recommended.

  • DrugInitial Conservative Strategy

    Optimal medical therapy (OMT) alone, with invasive coronary angiography (CAG) reserved only for failure of optimal medical therapy, defined as recurrent or worsening symptoms despite maximally tolerated medical therapy, or the occurrence of an acute coronary event.

    Healthcare resource utilization (including hospitalizations, procedures, and outpatient visits) will be collected and used to estimate total healthcare costs. Cost-effectiveness will be assessed using the incremental cost-effectiveness ratio (ICER), expressed as cost per quality-adjusted life year (QALY) gained. These components will be analyzed within a unified economic evaluation framework.

    Time frame: From baseline to 3 years; assessed at 1 month, 6 months, 1 year, 2 years, and 3 years

Start is estimated for Dec 2026; primary completion for Jul 2031, 55 months later.

Of 753 non-industry interventional studies with no phase under Coronary Artery Disease, half reached primary completion within 33 months of starting (the median), counting those still running; a quarter within 15 and three quarters within 53. This study's planned 55 months is above that.

Counting every sponsor, half of 930 studies reached it within 30 months; a quarter within 15 and three quarters within 50.

Start moved once since we started tracking on Sep 25, 2026: Jul 2026 → Dec 2026, on Oct 21, 2026.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
