Risk Factors for Early Complications of Acute Coronary Syndromes Seen in the Cardiology Department of Befelatanana

Abstract

This pathology remains a major public health problem because of its frequency and its impact on the morbidity and mortality of patients. According to the World Health Organization (WHO), it is responsible for nearly seven million deaths per year, i.e. 12.8% of global mortality [2]. In Europe, there has been a general trend towards a decrease in ischemic heart disease mortality over the last three decades [3]. Yet, in- hospital mortality ranges from 4% to 12% [4]. The prevalence of this disease is gradually increasing in sub-Saharan Africa due to the change in lifestyle in urban areas [5]. It was 13.5% in Côte d'Ivoire in 2016 and 5.1% in Kenya in 2012 [6, 7]. In Madagascar, we do not have national data, we have the 
impression that this condition has become increasingly common.It is a diagnostic and therapeutic emergency because it is lifethreatening in the short, medium and long term due to the numerous complications that may arise during its evolution [1]. These complications are becoming less and less frequent in developed countries [3]. The lack of technical facilities and the high cost of ACS management favor the occurrence of complications in subSaharan Africa, as is the case in Madagascar. Thus, we propose this study to identify the risk factors of early complications during ACS, in order to act upstream.
