VANERIO BALBELA, Gabriel et al. ¿Se puede predecir el riesgo de muerte súbita luego de sufrir un infarto de miocardio?. Rev. Méd. Urug. [online]. 2006, vol.22, n.4, pp. 249-265. ISSN 0303-3295.
Summary Sudden death is responsible of more than half of cardiac related death. Prediction of patients at high risk of sudden death has improved but more than 90% of deaths coincide with unidentifying risk factors free-people. More over, we know that most of them present a previous coronary disease and also that cardiac sudden death is essentially an extrahospitalarian problem. Myocardial arrest is a factor to easily detect groups with high mortality rates. Mortality rates after myocardial infarction range from 5 to 11%, within six to 12 months after release and 20% at five years. Although many markers have been identifying, their predictor value is relatively low. Specific markers were described and reviewed to stratify sudden death risks; left ventricular disfunction is one of the principal marker; others as follow: clinical, based on images, autonomics and electrocardiographics, besides biomarkers, invasive and combined methods. Risk stratification is designed according to clinical history, functional class and left ventricular ejection fraction (LVEF/FEVI). At first, patients at high risk should receive beta-blockers, enzyme converted inhibitors, spironolactone and antithrombotics. In many cases, cardiodefibrillator implantation should be considered.
