Chocolate consumption and infarction Int J Cardiovasc Sci. 2019;32(6):576-582 Original Article per daywas correlatedwith the variables of AMI severity using Spearman’s correlation. In this study, p < 0.05 was considered statistically significant.  The Catarina Heart Study was submitted to the Research Ethics Committee of Instituto de Cardiologia de Santa Catarina pursuant to Resolution 466/12, under the protocol 55450816.0.1001.0113. The patients were informed about the secrecy of the information collected in the questionnaire, and signed a consent form before applying the questionnaire. Results From July 2016 to July 2018, 350 patients aged 59.0 ± 11.0 years were evaluated. Most patients were males (64.0%) and hypertensive (58.3%). Regarding chocolate, 21.1% of the patients consumed it regularly, while Syntax presented a median value of 12.0 (6.0 — 19.0). The prevalence of diabetes mellitus in the interviewed population was 23.1% and the diagnosis of infarction with ST-segment elevation was delivered in 169 patients (48.0%). Median chocolate consumption among those who had chocolate was 21.5 grams per day. The other variables are presented in Table 1. The study showed an association between chocolate consumption and the absence of systemic arterial hypertension: 43.2% of the patients who consumed chocolate were hypertensive, while 62.3% of those who did not eat the food had hypertension (p = 0.003). Likewise, there is a significant association between absence of diabetes mellitus and consumption of chocolate: 13.5% of patients who consume chocolate have the disease, while 25.7% of those who do not eat chocolate have diabetes, with p = 0.027. There was a higher prevalence of smokers among patients who did not consume chocolate (37.7%) compared to those who consumed chocolate (24.3%), with p = 0.032. In addition, there was greater consumption of alcoholic beverages among those who consume chocolate (40.5%) compared to thosewho do not consume chocolate (26.4%), with p = 0.018. The group that used drugs was bigger among those who consumed chocolate (9.5%), compared to those who do not consume chocolate (3.3%), with p = 0.023. Dyslipidemia and family history of cardiovascular diseases were not associated with chocolate consumption. (Table 2).
