Clinical Registry on Sudden Death Primary Prevention at Latin America

Biotronik SE & Co. KG

Overview

INTRODUCTION: Sudden cardiac death is one of the most important reasons of death at industrialized countries. Despite its importance, nowadays Clinical Guidelines are not as extended as expected, with respect to indications for primary prevention defibrillator implantation, following MADIT II and MUSTT criteria, especially at Latin American countries. OBJECTIVES: This Project is designed with the purpose of providing tools to help spreading primary prevention by the means of clinical evidence on real risk of death in this group of patients. REGISTRY DESIGN: * retrospective (at stage 1); prospective (at stage 2) * multi-center (minimum 25-30 centres) * international (Argentina, Brazil, Colombia, Chile, Mexico and Venezuela) * non randomized. * Sample size: at screening about 12.500 patients and 962 patients at treatment stage REGISTRY DEVICES: CE marked (Conformité Européenne) single-chamber, dual-chamber or CRT (Cardiac Resynchronization Therapy) implantable cardiac defibrillator (ICD).

REGISTRY STAGES 2 stages will be performed: * Stage 1 (Screening): 12500 patients with MI and LVEF\<40% will be evaluated, to know ICD implantation prevalence in such patients at Latin American countries * Stage 2 (Treatment): after patient screening and as per clinical decision, 962 patients will be entered in group 1 and 2 (481 each, 1:1) STEERING COMMITTEE * Dr. Sergio Dubner.

REGULATORY CONSIDERATIONS As this is an observational registry, no submission to National Authorities is required.

Medical Language ↔ Plain English

Inclusion Criteria: * Patients that had Acute Myocardial Infarction (\>40 days post-AMI) documented with the presence of Q-wave or cardiac-specific enzymatic markers of myocardial necrosis (CK-MB/troponin), occurred within 3 years previous to enrollment / after June 2008. * Left Ventricular Ejection Fraction (LVEF) ≤40% post-revascularization (if no revascularization, measurement performed \<3 months previous to patient enrollment, \>40 days post-AMI and \>3 months post-revascularization -if applicable-). Exclusion Criteria: * Patient with an implanted ICD * \<18 years old * Pregnant or breast feeding women * Patients that are already participating in other Investigational Study or Registry * Non signed patient informed consent or refusal from patient's reference physician to patient participation * Patient inability to comply with protocol (assist to scheduled follow-ups), due to: residence displacement out of center's activity area; unstable geographical situation or at very long distance from the center; unstable medical and/or psychological condition * Cardiac transplanted (or in transplant waiting list) * Severe Heart Failure (or other co-morbidity: cancer, renal failure, etc.) * Life expectancy lower than 1 year

Outcomes

Primary Outcomes

Prevalence of patients with MADIT, MADIT II and MUST at Latin American countries

Primary Outcome at Stage 1: Determine prevalence of patients with myocardial infarction and high risk of sudden death at Latin America, that fulfill inclusion criteria Primary Outcome at Stage 2: Compare MACE development in patients that receive ICD implantation vs patients that receive other type of treatment (non ICD)

Time frame: Patients that suffered from MI in the last 3 years and during the enrollment period

Secondary Outcomes

Study incidence of Arrhythmic mortality and serious arrhythmic events, evaluated through remote monitoring

Time frame: 5 years (until end 2018)
