Americanii testează ”inima bionică”, pentru testarea valvelor cardiace artificiale
”Inima” de pe Pluto este sursa transformărilor atmosferice a acestei planete
Se lucrează la prima inimă robotizată. Obţinută cu ajutorul celulelor stem şi al biotehnologiei, ar putea rezolva o problemă majoră:format(wepb):quality(80)/https://www.descopera.ro/wp-content/uploads/sfm/2026/02/1741781917/2f124859762d49e409e3326eeb907772-t.jpg)

Iată listă:
Oboseală. Atunci când arterele devin congestionate, inimă primeşte mai puţin sânge şi lucrează mai mult decât ar trebui.
Probleme de respiraţie. Atunci când inimă primeşte mai putn sânge, nici plămânii nu vor primi la fel de mult oxigen.
Slăbiciune. Dacă simţi o stare de slăbiciune dintr-odată, înseamnă ca nu primeşti sânge îndeajuns de mult în zonă inimii. Muşchii nu mai sunt oxigentati corespunzător.
Ameţeli şi transpiraţii reci. Circulaţia proastă face că fluxul sanguin către creier să fie restricţionat. De aceea, te vei simiţi ameţită.
Presiune în piept. Această va creşte în intensitate până în momentul atacului de cord.
Simptome de răceală. Dacă apar de nicăieri, este posibil că atcul să aibă loc în viitorul apropiat.
Trombocitele pot transporta în mod eficient medicamentele către inimă după un atac de cord
