About this trial

The goal of this observational study is to learn about the genetic insights of arrhythmya-induced cardiomyopathy and its clinical prognosis. The main questions it aims to answer are:

I. Does patients with arrhythmia-induced cardiomyopathy have a greater proportion of genetic mutations compared with other types of cardiomyopathy or general population? II. Have the genetics any prognostic impact in patients with arrhythmia-induced cardiomyopathy?

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Presence of atrial fibrillation or atrial flutter not self-limited.

Performance of a cardiac imaging test with systolic function analysis (echocardiogram, magnetic resonance, CT scan) during the clinical course of the arrhythmia, exhibiting a left ventricular ejection fraction (LVEF) <50%. In order for the test to be representative, the maximum time between the performance of the imaging test and the rhythm control procedure will be 3 months, in the absence of intervening cardiovascular events that may have caused a variation in LVEF. In the event that the patient had a previously known LVEF <50%, the change with respect to this attributable to tachyarrhythmia has to be ≥10%.

Trial outcomes

Primary outcomes

1

Prevalence of pathogenic or likely pathogenic variants in genetic test

Presence of pathogenic/likely pathogenic genetic variant in genetic test

Time frame
Through study completion, an average of 1 year

Secondary outcomes

1

Heart Failure Admission

Incidence of new hospitalización or urgent visit due to heart failure requiring intravenous diuretics

Time frame
Through study completion, an average of 1 year
2

Arrhythmia recurrence

Incidence of any atrial tachyarrhytmia (Atrial fibrillation, atrial flutter or atrial tachycardia) conditioning an atrial rate \>150 beats per minute and with a duration of \>5 minutes.

Time frame
Through study completion, an average of 1 year
3

Time frame
Through study completion, an average of 1 year
2

Mortality
