Acute coronary syndromes: epidemiological, clinical, paraclinical and therapeutic characteristics at the Campus teaching hospital of Lome, Togo

Introduction: The aim of this work was to describe the epidemiological, clinical, and therapeutic characteristics of acute coronary syndromes (ACS) in the cardiology department of Lome Campus University Hospital in Togo. Methodology: We conducted a prospective study that consistently included patients hospitalized from 2014 to 2017 for ACS, based on clinical, electrocardiographic, and laboratory findings. Results: Of 1914 patients admitted to the department during the study period, 67 were admitted for ACS, for a 3.5% prevalence. The (M/F) sex ratio was 1.91. Patients' mean age was 60 +/- 12 years. The clinical presentation was an ST elevation myocardial infarction (STEMI) in 71.6% of cases, and non-STEMI in 28.4% of cases, including 18.1% non-Qwave infarction and 10.3% unstable angina. The mean time to admission after the onset of symptoms was 81.9 +/- 124.6 hours. Patients were transported to the hospital by a private vehicle in 82.1% of cases. Thrombolysis was performed for 14.6% of patients (7/48 patients with ACS STEMI), with a success rate of 85.7% (n=6). In-hospital mortality was 10.5% (7/67). This mortality was significantly associated with the interval from onset of symptoms to admission and with the Killip stage. Conclusion: Acute coronary syndromes are increasingly common in Togo. They are characterized by a relatively young age and a long delay until admission. Improving the management of these conditions in our countries requires effective primary prevention.
