[Ventricular arrhythmia and device intervention analysis in patients with implanted cardioverter-defibrillator with/without resynchronisation therapy in dilative cardiomyopathy in primary prevention of sudden cardiac death in telemetric follow-up].

INTRODUCTION

Remote monitoring of ICD/CRTD is safe, during which evaluates the type of arrhythmia, intervention.

AIM

The aim of the study was the assessment of ventricular arrhythmia and ICD/CRTD intervention.

MATERIAL AND METHODS

The study included 177 patients (mean age 61,1±13; 23-88 y; Men 141) with an ICD/CRTD implanted. Patients were controlled telemonitoring system, Medtronic Carelink. The following variables were analyzed: age, gender, comorbidities, LVEF value, NYHA class, type of ventricular arrhythmias, device interventions, reprogramming and pharmacotherapy changes.

RESULTS

In multivariate analysis, it was found that, diabetes mellitus (HR 3,49), a low ejection fraction <25% (HR 2,51) predispose to ventricular arrhythmias; and a low ejection fraction <25% (HR 1,88), ischemic DCM (HR 1,92), II NYHA class, the lack of Amiodarone (HR 5,01) predispose to device intervention.

CONCLUSIONS

1. A low ejection fraction, ischemic dilative cardiomyopathy, II NYHA class, the lack treatment of Amiodarone predispose to ventricular arrhythmias. 2. A low ejection fraction, diabetes mellitus predispose to device intervention. 3. A significant correlation between interventions and ventricular arrhythmias, renal failure, diabetes mellitus, abnormal lipidogram were observed. 4. Telemetric follow-up of cardiac implantable devices is a safe and enables quick information transmission in cases of clinical complications (arrhythmias, interventions).
