The Clinical Monitoring Effect of Intracardiac Morphology Changes in Patients with Defibrillator Device

&nbsp;84 patients who applied to our clinic for device control were included in the study. Morphological changes, SF-12 quality of life score, comorbities, current laboratuary tests and current echocardiograms were performed as part of the device control . Every patient who were device owner, regardless of heart falure, was included in the study.The aim of our study was to demonstrate the relationship between intracardiac morphological changes and clinical parameters and patient characteristics, as well as to how whether this value could predict patient fallow-up and clicial outcomes in outpatient monitoring. According to our hypothesis, device morphology should detect ongoing cardiac remodelling, which could have a role in HF monitoring. It was shown that patients with high BNP levels in laboratory values (p:0,058) might have lower morphologies approaching statistical significance. It was also demonstrated that the morphological value was higher patients with secondary prophylaxis implantation. This was consistent with our hypothesis, as the proportion of HF patients is much lower among patients with secondary prophylaxis, and there were different types of cardiomyphaties among this patients. Significant correlation between valve insufficiencies and morphological changes could not demonstrated in the echocardiograms performed for each patient. Although the EF value was higher on average in patients with a morphology score of 100 (39,3-35-2), it did not reach statistical significance (p :0,18) Nevertheless, it was shown that in echocardiograms, the diameters obtained by dividing the diastolic and systolic diameters by the body surface area were larger in patients with lower morphology scores (p: 0.03). As a secondary endpoint, when the hospitalization rates of patients due to decompensation after device implantation were examined, patients with a morphology change of 2 or above during the control had 5.6 times higher hospitalization rates (p: 0.02). This result was consistent when evaluated with multiple regression analysis. This indicates that morphological changes could be involved in the follow-up of patients with implantable cardioverter-defibrillator devices.</p
