ABSTRACTIntroduction: Determining the prognosis of patients with ischemic cardiomyopathy is a requirement of the clinical method and a challenge for the intensives.
Objective: To identify the associate factors of heart arrhythmia mortality in patients with ischemic cardiomyopathy.
Method: An observational, analytical, retrospective and longitudinal study was conducted in the intensive care unit at Dr. Agostinho Netoˮ Hospital. The patients were grouped according to their discharge into deaths due to cardiac arrhythmia (N= 12) or alive (N= 38). We analyzed clinical variables, echocardiography, electrocardiography, personal history, and patient status at discharge. We calculated the absolute risk of the most frequent variables and those most related to the probability that the patient died. A patient probability model was designed if the patient died due to cardiac arrhythmia with ischemic cardiomyopathy.
Results: The variables most associated with the prognosis of dying were the signs of pulmonary congestion, cardiac cyanosis and segmental dysfunction, and increase in left ventricular end-diastolic diameter (ultrasound). The absolute risk for these variables was 22.4.
Conclusion: We identified the factors associated with the risk of the patient with ischemic cardiomyopathy of dying due to cardiac arrhythmia, which enabled the elaboration of a probability of death model due to this cause. The presence of signs of pulmonary congestion, segmental dysfunction and the increase in left ventricular end-diastolic diameter were this risk most related factors.
