Despite this dilatation, we observed that the remote part of the CX3CR1−/− hearts seem to develop a certain grade of hypertropia compared with the wild type, probably due to the adaptation to increase dilatation of the infarcted area, mitigating the possible difference between the two groups when included in the calculations (the infarction volume was calculated and presented as percentage of entire heart volume). Here, CX3CR1 is linked to infarction.
