Cardiac Conduction Disorders in Acute Coronary Syndrome with St Elevation: Study of 51 Cases

Introduction: Cardiac conduction disorders are complications that can occur in the early development of acute coronary syndrome with ST segment elevation and have a significant influence on the patients prognosis. Objective: The determine the epidemiological clinical and therapeutic aspects of conduction disorders with elevation in the ST segment. Methods: We have performed a descriptive retrospective study of 51 cases of conduction disorder among 228 cases of coronary syndromes with ST segment elevation. Results: The prevalence of cardiac conduction disorders was 14.1% over a period of 4 years. The average age of our patients was 59 years old (extremes: 42 to 81 years old). Diabetes was the most prevalent risk factor (52.4%). Low location was the most found (56%) and conduction disorders were dominated by atrioventricular block (45.09%).Coronary angiography was performed in all our patients. The found lesions in coronary angiography concerned more the right coronary (37.3%) and circumflex artery (34.1%). Coronary angioplasty has been performed in 72 % of cases, and thrombolysis in 9, 8%. The implantation of temporary pace maker was done in 33% of cases. The evolution was favorable for all our patients. Conclusion: Conduction disorders in ST-segment elevation coronary syndrome should be diagnosed early for timely and adequate management in order to reduce the high objective mortality rates.
