Background: Ischaemic heart disease is the cause of 7.4 million deaths per year. Their prevention is based on the management of cardiovascular risk factors, but also on the early detection and management of chronic coronary syndromes (CCS), for which few data are available in Africa. The main objective of our study was to determine the factors related to significative coronary artery disease in patients undergoing coronarography for suspected chronic coronary syndrome (CCS). Methodology: We conducted a retrospective descriptive and analytical study over 2 years (from January, 1^st, 2018 to December 31^st, 2019) in the Cardiology Department of the University Hospital Aristide Le DANTEC in Dakar. All patients admitted for coronary angiography for suspected chronic coronary syndrome were included. Results: One hundred and fifty-two patients were included with a mean age of 60.79 ± 9.73 years, the most represented age group was 60 - 69 years. Advanced age was the most frequent risk factor (77.63%) followed by sedentary lifestyle (56.58%) and hypertension (41.45%). Diabetes was present in 17.1% of cases. A history of angioplasty was found in 1.97% of patients. Typical pain was found in 71.05% of cases, atypical pain in 19.74% and exertional dyspnoea in 2.63%. The pre-test probability was intermediate in 67.1% of cases, low in 25% and high in 7.9%. Significative coronary lesion was found in 52.63% of the patients, while coronary angiography was normal in the remaining cases. Tritroncular status was observed in 37.50%, it was bitroncular in 26.25% and monotroncular in 36.25% of cases. Factors associated with significative coronary artery disease were age (p = 0.0001), diabetes (p = 0.006), previous angioplasty (p = 0.023), previous myocardial infarction (p = 0.018), typical angina (p = 0.001), intermediate pretest probability (p = 0.001). Low pretest probability was significantly correlated with the absence of a coronary lesion with a p = 0.001. Conclusion: Our study shows that screening for chronic coronary disease should be done especially in diabetics, elderly subjects and those with previous angioplasty taking into account symptoms and pretest probability to avoid unnecessary invasive procedures.
