Risk Relationship Between Microplastics and Cardiovascular Events: An Integrative Review
Original title: Relação De Risco Entre Microplásticos E Eventos Cardiovasculares: Uma Revisão Integrativa.
AI summary Read the abstract
This review of five studies found a possible link between microplastics (tiny plastic particles from broken-down waste) in the body and heart problems, including higher rates of clogged arteries, stroke, and blood clotting markers. People living in areas with more plastic pollution or in lower-income communities seemed to face greater exposure and risk, suggesting environmental cleanup and further research could matter for heart health. That said, this is early evidence from a small number of studies, so it points to a concerning pattern rather than proof that microplastics directly cause heart disease.
Introdução: A grande produção de plástico e o descarte irregular do material são um dos principais problemas ambientais da atualidade, pois seus resíduos permanecem na natureza por longos períodos, degradando-se em partículas cada vez menores até a forma de microplásticos (MP). As doenças cardiovasculares, por sua vez, são a principal causa de morte em todo o mundo, sendo importante avaliar possíveis correlações. Objetivos: Buscar na literatura científica se os MP são fatores de risco para eventos cardiovasculares em humanos. Métodos: Realizou-se uma revisão integrativa de literatura nas bases de dados Embase, PubMed/MEDLINE e LILACS via Biblioteca Virtual de Saúde (BVS). Na Embase, buscaram-se trabalhos que tivessem no título ou no resumo os descritores do Entree: “microplastic” ou “nanoplastic” e “cardiovascular diseases”. Para as outras bases adaptou-se usando os termos do DeCS: “microplastics” ou “nanoplastics” e “cardiovascular diseases”. Em seguida aplicou-se os critérios de exclusão, retirando artigos repetidos, outras revisões de literatura, fora de escopo e fora do período de 2022 a 2026. Resultados e Discussão: Encontrou-se 46 artigos (21 Embase, 22 PubMed e 3 LILACS). Após a aplicação dos critérios de exclusão, selecionaram-se 5 artigos (3 PubMed e 2 Embase) para análise aprofundada. Encontrou-se uma forte correlação entre a concentração de MP sanguíneo e a gravidade da estenose arterial extracraniana de 20 pacientes em um estudo de análise da presença de polímeros no sangue, indicando um possível envolvimento fisiopatológico. Também observou-se que níveis elevados de dímero-D e fibrinogênio, foram positivamente associados à concentração sanguínea de MP, sugerindo um estado pró-trombótico potencialmente relacionado à inflamação vascular. Autores observaram que pacientes com calcificação da parede da aorta apresentavam níveis mais elevados de MP de poliestireno nas fezes. Enquanto outros, compararam 152 condados costeiros nos Estados Unidos, sendo aqueles com níveis elevados de MP marinho os condados com maior prevalência de doença arterial coronariana e AVC. Em estudos, foi constatado que populações socioeconomicamente desfavorecidas apresentavam maior exposição a MP na dieta, que foi significativamente associada ao aumento da carga global de doenças cardiovasculares. Os estudos, mesmo utilizando métodos diferentes, chegam a uma possível relação de risco. Fatores socioeconômicos e ambientais também mostraram impacto relevante na exposição a MP e nos desfechos cardiovasculares. Conclusão: Os estudos analisados sugerem que a exposição a microplásticos pode estar associada ao risco de eventos cardiovasculares, especialmente em populações com maior vulnerabilidade socioeconômica ou residentes em regiões com elevada contaminação ambiental. Esses achados evidenciam a necessidade de pesquisas regionais que avaliem, com rigor metodológico e analítico, os possíveis impactos cardiovasculares dos microplásticos na população brasileira.

Risk Relationship Between Microplastics and Cardiovascular Events: An Integrative Review
AI summary Read the abstract
This review of five studies found a possible link between microplastics (tiny plastic particles that get into our bodies through food, water, and air) and heart problems like clogged arteries, blood clots, and strokes. People with higher microplastic levels in their blood or diet—especially those in lower-income communities or heavily polluted areas—seemed to have worse cardiovascular outcomes, though more research is needed to confirm this connection is truly cause-and-effect. Still, it's a good reminder that reducing plastic exposure in daily life may be worth considering for heart health, not just environmental reasons.
Micro- and Nanoplastics as Emerging Cardiovascular Risk Factors: A Systematic Review
AI summary Read the abstract
Scientists reviewing 14 studies found tiny plastic particles (microplastics and nanoplastics) showing up in people's blood, blood vessels, and artery plaques, with possible links to heart attacks, strokes, high blood pressure, and blood clotting problems. However, the evidence is still weak and doesn't prove plastics actually cause these heart problems—more rigorous research is needed before we can say for sure. Bottom line: this is an early warning worth watching, not yet a confirmed health threat.
Emerging Links Between Cardiovascular Disease and Microplastics Exposure – A Narrative Review
AI summary Read the abstract
This review of existing research shows that tiny plastic particles called microplastics may be linked to heart disease - scientists have even found these particles inside the fatty buildups that clog arteries. When microplastics get into our bodies through food, water, and air, they appear to cause inflammation and damage blood vessels, which could increase the risk of heart attacks and strokes. People who eat lots of seafood, drink bottled water frequently, or work in certain industries may face higher exposure to these harmful plastic particles.
Microplastics, Nanoplastics, and the Cardiovascular Exposome: Emerging Evidence for Vascular Deposition, Thrombotic Pathways, and Cardiovascular Risk
AI summary Read the abstract
This review pulls together existing studies on tiny plastic particles found in blood vessels and artery plaque, some of which link their presence to higher rates of heart attack, stroke, and death. However, these studies show a connection, not proof that plastics cause these problems. Scientists say more research is needed before doctors should test for plastics or change how they treat heart disease.
Micro- and Nanoplastics in Cardiovascular Toxicology: Human Tissue Detection, Clinical Phenotypes, and Adverse Outcome Signals
AI summary Read the abstract
Scientists are finding tiny plastic particles (called micro- and nanoplastics) lodged in human blood, arteries, and even fatty plaque buildup in blood vessels — and one major study found people with plastic particles in their neck artery plaque were over 4 times more likely to have a heart attack, stroke, or die during follow-up. This review pulls together lab and human research showing these plastics may cause inflammation, blood clotting, and heart tissue damage, though scientists stress this doesn't yet prove plastics *cause* heart disease — it shows a concerning link that deserves more attention and research.
