Abstract
Aortic Stenosis (AS) is a form of valvular heart disease that it is in increasing rate nowadays. No effective drug treatment for AS is available. In this way, the analysis of AS with a noninvasive technic such as the analysis of the heart rate variability (HRV) can be a high advance for early cardiac disease detection. In this project, it was analyzed 24-hours Heart Rate Variability (HRV) of patients with Aortic Stenosis which have underwent aortic valvular replacement, suffering some of them sudden cardiac death during the follow up. The HRV has been analyzed by applying a methodology base on symbolic dynamics, using a Non-equidistant (NEQ) algorithm and an equidistant (EQ) algorithm. From this methodology, several variables were proposed and validated for their prediction ability, in order to differentiate groups of patients with different cardiac risk of suffering sudden cardiac death. In this way, the RR cardiac time series analysis has permitted to statistically describe patients that died for cardiac reasons during the valvular surgery (Operdeath), those that died five years after the surgery (Death-five-years) and all patients that died during the follow-up of the five years (Death-alive-total). Furthermore, RR cardiac series analysis has permitted to statistically describe patients with different levels, Left Ventricular Ejection Fraction (LVEF) and New York Heart Association (NYHA).
