Is discrepancy between increased left ventricular mass and `` normal '' QRS voltage associated with decreased connexin 43 expression in early stage of left ventricular hypertrophy in spontaneously hypertensive rats?
The QRS voltage did not follow the increase in the LVM in 20-week-old SHR, and the values of connexin 43 were lower in SHR than in normotensive controls. We believe that the discrepant findings between ECG voltage and LVM can be caused by the electrical remodeling in the early stages of LVH.
Based on our results, MSX2 plays a pivotal role in the development of IPMN through growth stimulation of tumor cells, and its expression was identified as an independent predictive factor for malignancy of BD-IPMN.
