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<sup>st</sup>, 2018 to December 31<sup>st</sup>, 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.展开更多

Methods In this study, we enrolled 103 patients aged 75 years or older with chronic angina in which 47 patients were assigned coronary angiography and revascularisation and 56 patients with optimised medical therapy. The primary endpoint was quality of life after 6 months, as assessed by questionnaire and the presence of major adverse cardiac events (death, non fatal myocardial infarction, or hospital admission for acute coronary syndrome with or without the need for revascularisation). Results After 6 months follow up, angina severity decreased and measures of quality of life increased in both treatment groups( P <0.05 ); however, these improvements were significantly greater after revascularisation( P <0.01 ). Major adverse cardiac events occurred in 30 ( 53.6% ) of patients in the medical group and 9 ( 19.1% ) in the invasive group ( P <0.01 ).Conclusions Patients aged 75 years or older with angina benefit more from revascularisation than from optimised medical therapy in terms of symptom relief and quality of life. Therefore, these patients should be offered invasive assessment despite their high risk profile followed by revascularisation if feasible.展开更多

However,there were few data related to the long-term clinical outcomes after percutaneous coronary intervention(PCI)between ISR CTO and de novo CTO. Methods A total of 435 CTO patients who had attempted PCI between Jan 2013 and November 2017 were screened for inclusion in this study. The Kaplan-Meier method was applied to estimate event-free survival and the log-rank test to compare long-term outcome. Cox regression analysis was used to identify associations between adverse events and risk factors. Results There were84 ISR CTO cases and 351 de novo CTO cases in this study. Successful revascularization was achieved similar between ISR CTO group and de novo CTO group(84.5% vs. 87.2%,P=0.592). The prevalence of MACE[17.9% vs. 9.1%;hazard ratio(HR):2.323;95% confidence interval(CI)1.233-4.37;P=0.004]and TLR(8.3% vs. 3.4%;HR:2.627;95% CI 1.05-6.53;P<0.016)were higher in the ISR CTO group,during the 2-year follow-up. Conclusions The procedural success rate of ISR CTO achieved was comparable to that of de novo CTO in the contemporary practice. But the long-term clinical outcome was significantly worse in term of major adverse cardiac events and target lesion revascularization.展开更多

The Kaplan-Meier method was applied to estimate event-free survival and the log-rank test to compare long-term outcome. Cox regression analysis was used to identify associations between adverse events and risk factors. Results There were84 ISR CTO cases and 351 de novo CTO cases in this study. Successful revascularization was achieved similar between ISR CTO group and de novo CTO group(84.5% vs. 87.2%,P=0.592). The prevalence of MACE[17.9% vs. 9.1%;hazard ratio(HR):2.323;95% confidence interval(CI)1.233-4.37;P=0.004]and TLR(8.3% vs. 3.4%;HR:2.627;95% CI 1.05-6.53;P<0.016)were higher in the ISR CTO group,during the 2-year follow-up. Conclusions The procedural success rate of ISR CTO achieved was comparable to that of de novo CTO in the contemporary practice. But the long-term clinical outcome was significantly worse in term of major adverse cardiac events and target lesion revascularization.
