Bottom Line: Chagas' disease was present in 49 cases (5.5%).The majority of victims of SCD were men, in their sixties and seventies and the main cause of death was CAD.Chagas' disease, an important public health problem in Latin America, was found in about 5.5% of the cases.

ABSTRACT

Background: Sudden cardiac death (SCD) is a sudden unexpected event, from a cardiac cause, that occurs in less than one hour after the symptoms onset, in a person without any previous condition that would seem fatal or who was seen without any symptoms 24 hours before found dead. Although it is a relatively frequent event, there are only few reliable data in underdeveloped countries.

Objective: We aimed to describe the features of SCD in Ribeirão Preto, Brazil (600,000 residents) according to Coroners' Office autopsy reports.

Methods: We retrospectively reviewed 4501 autopsy reports between 2006 and 2010, to identify cases of SCD. Specific cause of death as well as demographic information, date, location and time of the event, comorbidities and whether cardiopulmonary resuscitation (CPR) was attempted were collected.

Results: We identified 899 cases of SCD (20%); the rate was 30/100000 residents per year. The vast majority of cases of SCD involved a coronary artery disease (CAD) (64%) and occurred in men (67%), between the 6th and the 7th decades of life. Most events occurred during the morning in the home setting (53.3%) and CPR was attempted in almost half of victims (49.7%). The most prevalent comorbidity was systemic hypertension (57.3%). Chagas' disease was present in 49 cases (5.5%).

Conclusion: The majority of victims of SCD were men, in their sixties and seventies and the main cause of death was CAD. Chagas' disease, an important public health problem in Latin America, was found in about 5.5% of the cases.

Mentions: Between 2006 and 2010, 4,501 autopsies were performed in Ribeirão Preto. Initially,2,053 cases were selected as possible SCD; however, after careful analysis, 718 caseswere excluded for not meeting all the criteria for SCD, as well as 256 cases due toincomplete information. In 180 cases, a noncardiac cause of sudden death wasidentified: 99 cases of acute aortic syndrome, 58 cases of pulmonary embolism, 21cases of hemorrhagic CVA and two cases of asthma. Therefore, 899 cases (20% of allautopsies) were defined as SCD (Figure 1). SCDrates ranged from 28/100,000 inhabitants in 2009 to 32/100,000 inhabitants in 2007and 2008 (Figure 2). There was no difference inSCD rates between the years (p = 0.88).
