Microplastics and nanoplastics in people with chronic coronary syndromes

Official title: Microplastics and Nanoplastics in Patients With Chronic Coronary Syndromes

Run by Azienda Ospedaliera "Sant'Andrea" · NCT07291609 · Data updated 2026-11-12

This study will test whether tiny plastic particles (micro- and nanoplastics) can be detected in the coronary blood of adults with suspected or known chronic coronary syndromes who are having coronary CT and invasive angiography.

Is this trial a fit for you?

Likely a good fit

Adults over 18 with suspected or known chronic coronary syndromes who undergo coronary CT angiography and have a clinical indication for invasive coronary angiography and can give informed consent are ideal candidates.

Probably not a fit

Patients without a usable coronary CT angiogram, with poor-quality CCTA, without ≥50% native coronary stenosis on CCTA, unable to undergo invasive angiography, or with life expectancy under one year from non-cardiac causes are unlikely to benefit from participation.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This is a prospective, multicenter observational project enrolling adults referred for coronary CT angiography who have a clinical indication for invasive coronary angiography. During invasive angiography, coronary blood samples will be collected and sent to a central core laboratory for centralized analysis of micro- and nanoplastics (MNPs) and related biomarkers. Routine clinical care and treatment decisions will not be changed by participation. Patient dossiers and imaging will be uploaded to a core lab for standardized review and correlation with coronary plaque and stenosis.

Why it matters

Potential benefit: If successful, the findings could reveal whether micro- and nanoplastics are present in coronary blood and suggest a possible environmental contributor to coronary plaque, informing future prevention or diagnostic work.

How similar studies have gone: This is largely a novel approach in coronary disease: a few early human studies have detected microplastics in blood or tissues, but links to coronary plaque and clinical outcomes remain unproven.
