| Popis: | Objective: Heart failure with preserved ejection fraction corresponds to half of the cardiac failure cases, having a similar prognosis to patients with reduced ejection fraction. Cardiac sudden death is responsible to about one quarter of the death on these patients. The objective of this study is to review published studies, seeking to identify the high-risk factors for sudden cardiac death in this population.Methods: This work is a literature review on the most recent articles that assess the profile of patients with cardiac sudden death and cardiac failure with preserved ejection fraction. Results:Several trials were published involving patients with diverse characteristics that can help to identify patients with a higher risk of sudden death. The publication of risk score demonstrated that would be possible to identify patients with a > 10% risk of sudden death in 5 years, what would be equivalent to the risk of reduced ejection fraction patients eligible to implantable cardioverter-defibrillator (ICD) therapy. Trials with electrophysiological study and programmed ventricular stimulation showed a good strategy to identify low risk patients for future arrhythmic events.Conclusion: Sudden death must be a target of the therapy in the patients with preserved heart failure. Efforts should be done with the objective to identify higher risk patients and search for the better risk stratification strategy, and after that, the definition of the benefit or not of an invasive therapy such as ICD. |
