Ara\u015ft\u0131rmac\u0131lar, ameliyat s\u0131ras\u0131nda al\u0131nan 17 insan atardamar\u0131 \u00f6rne\u011finin tamam\u0131nda mikroplastik par\u00e7ac\u0131klar belirledi. Ancak sekt\u00f6r temsilcileri, bu maddelerin kalp krizi ve felce do\u011frudan neden oldu\u011funun hen\u00fcz kan\u0131tlanmad\u0131\u011f\u0131n\u0131 vurguluyor.<\/p>\n

Ara\u015ft\u0131rmada cerrahi i\u015flemler s\u0131ras\u0131nda al\u0131nan 17 damar dokusu \u00f6rne\u011fi incelendi ve \u00f6rneklerin tamam\u0131nda mikroplastik bulundu.<\/p>\n
Journal of Hazardous Materials dergisinde yay\u0131mlanan \u00e7al\u0131\u015fmada koroner arter, \u015fah damar\u0131 ve aorttan al\u0131nan dokular analiz edildi. Ara\u015ft\u0131rmac\u0131lar, damarlardaki mikroplastik yo\u011funlu\u011funun daha \u00f6nce kanda tespit edilen seviyelerden g\u00f6rece y\u00fcksek oldu\u011funu bildirdi.

Bu sonu\u00e7, mikroplastiklerle damar sertli\u011fi aras\u0131nda olas\u0131 bir ili\u015fki bulunabilece\u011fi ihtimalini g\u00fcndeme getirdi. Damar sertli\u011fi olarak bilinen ateroskleroz, damarlar\u0131n i\u00e7 duvarlar\u0131nda ya\u011fl\u0131 plaklar\u0131n birikmesi sonucunda kan ak\u0131\u015f\u0131n\u0131n daralmas\u0131na yol a\u00e7\u0131yor. Bu durum kalp krizi ve fel\u00e7 riskini art\u0131rabiliyor.<\/p>\n
Edinilen bilgilere g\u00f6re, ancak ara\u015ft\u0131rmac\u0131lar, elde edilen sonucun do\u011frudan bir neden-sonu\u00e7 ili\u015fkisi g\u00f6stermedi\u011finin alt\u0131n\u0131 \u00e7iziyor.
