About this study

Official title: Angiographic Control Vs. Ischemia-driven Management of Patients Undergoing Percutaneous Revascularization of the Unprotected Left Main Coronary Artery with Second-generation Drug Eluting Stents: the PULSE Trial

The present study aims to compare a planned angiographic control (PAC) follow-up strategy vs. conservative management for patients treated with drug-eluting stents on unprotected left main artery in a prospective, randomized setting. PAC will be performed by coronary computed tomography (CCT), to avoid the limitations of the invasive coronary angiography which is usually employed to perform PAC. The superiority of a PAC-based approach will be tested on a hard clinical end-point such as the incidence of major adverse cardiovascular events. The investigators will also assess the performance of CCT as a tool to perform PAC.

Read the detailed description

Given the undefined picture surrounding the appropriateness of planned angiographic control (PAC) following percutaneous coronary intervention (PCI) of the unprotected left main (ULM) with drug-eluting stents (DES), our aim is to evaluate, in a prospective, randomized, setting, the potential benefits of a PAC-based strategy vs. ischemia and symptoms driven conservative management. The disease of the native ULM is associated with an unfavorable prognostic outcome, which can be at least partially reversed by revascularization. Significant stenosis of the stented ULM caused by in-stent restenosis (ISR), however, presents some peculiar pathophysiological, flow-related and shear-stress features, which partly makes it a distinct disease as compared to native vessel atherosclerosis. Treatment of ISR, moreover, is a scarcely standardized and often complex procedure; some uncertainties still persist regarding the best strategy to treat ISR (stent-in-stent, drug-eluting balloons, dilation with conventional balloons). Computed coronary tomography (CCT) can precisely and not-invasively assess the presence of ISR in the stented ULM, without exposing the patients to the risks of invasive catheterization. CCT may provide an accurate reconstruction of the stented vessels, exposing the patients to a limited amount of contrast dye (approximately, 80-100 cc) and of radiation dose (approximately, 92 mGy). CCT has a very high negative predictive value for ISR, thus limiting the negative impact of the indiscriminate execution of invasive angiography on all patients treated by PCI of the ULM. Only patients with relevant ISR of ULM at CCT will undergo coronary angiography to confirm the presence of critical stenosis, and fractional flow reserve (FFR) and/or intravascular ultrasound (IVUS) will be performed in dubious cases.

An increased rate of PCI has to be taken in to account with a PAC-based approach. However, with the accurate, stepwise selection of the patients and the lesions amenable to PCI of our study protocol, based on CCT, coronary angiography and, where necessary, FFR/IVUS, the increased rate of PCI is not expected to bear a negative prognostic impact. Based on these premises, our hypothesis is that early, appropriate, detection of ULM ISR and its subsequent treatment may positively impact patients' survival and reduce the incidence of adverse cardiovascular events.

Specific aim 1:

Evaluation of the effectiveness and safety of a PAC-based approach to follow-up patients treated by PCI of the ULM with DES-II

Specific aim 2:

Assessment of the incidence of ISR in patients undergoing PCI of the ULM with DES-II and evaluation of the diagnostic accuracy of CCT in the evaluation of ISR in the stented ULM

Specific Aim 3:

Assessment of the prognostic implications and safety of the PCI of ISR of the ULM detected by PAC as compared to conservative management with revascularization driven by symptoms and ischemia.

For this purpose in this prospective, randomized controlled trial (RCT), patients will be enrolled following the index percutaneous revascularization of ULM with DES. Patients will be randomized in a 1:1 fashion to PAC-based management with CCT vs.

symptoms and ischemia driven conservative management.

The record lists 3 sites in Italy. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Major adverse cardiovascular events (MACE) (time frame: 18 months after the index revascularization). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04144881, which also lists 22 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 4 Nov 2024.
