Heart-Attack Patients Show Higher Micro- and Nanoplastic Loads in Coronary Blood
Share
Association only — not causation. A September JAMA Medical News brief is putting a summer cardiology finding back in front of clinicians and consumers: patients presenting with heart attacks showed higher micro- and nanoplastic (MNP) detection in coronary blood than comparison groups.
The primary study is Paolisso and colleagues in the European Heart Journal (DOI 10.1093/eurheartj/ehag447), highlighted by the European Society of Cardiology press release (Jul 15, 2026). JAMA Medical News (Sep 11, 2026) amplifies that work for audiences who missed the July coverage — it is not net-new primary science.
In the Italian angiography cohort (n=61), MNPs were detected in roughly ~84% of STEMI patients versus about ~40% with chronic coronary syndromes (CCS) and about ~32% with normal coronaries (controls). Polyethylene (PE) dominated the polymer mix; concentrations were highest in coronary blood. Inflammatory markers IL-6 and TNF-α were also elevated in the STEMI group. Authors and editorialists stress association — not proof that plastics cause heart attacks — and note co-exposure with smoking and PM2.5.
Do not read this as “plastics cause heart attacks.” Observational detection in blood does not establish that MNPs trigger STEMI. Measurement science and exposure pathways (air, food, water) still outrun regulation.
Why this matters for WaterVo readers
WaterVo’s health frame stays careful: particles show up in the body via multiple pathways; clinical association keeps stakes visible without turning every bottle into a causation claim. Practical takeaways remain exposure-reduction literacy and support for better methods — not panic copy. Atmospheric water is one option that skips PET packaging; we do not claim it prevents coronary disease.
