Coronary artery disease and its clinical-angiographic characteristics: Reality of a private tertiary care center in Angola
Abstract
Introduction: Coronary artery disease has progressively increased among Angolans due to the epidemiological transition resulting from new lifestyles unfavorable to cardiovascular health.
Objective: To perform a clinical-angiographic characterization of patients suspected of coronary artery disease undergoing coronary angiography.
Method: Retrospective observational study, conducted at Clínica Girassol, with 450 patients who underwent coronary angiography from January 2012 to December 2018. Clinical variables such as sex, age, type of procedure, risk factors, clinical indication, and angiographic features (access route, vessels involved, coronary dominance, treatment strategy and complications) were included.
Results: Male sex predominated (71.6%) with a mean age of 59.7±11.2 years. Hypertension was the predominant risk factor (76.0%). Emergency procedures accounted for 56.2% of the interventions; ST-segment elevation acute coronary syndrome (37.3%) was the most frequent. Most of the procedures (81.1%) were performed via the femoral artery. The left anterior descending artery was involved in 37.6% of the cases and right dominance was the most prevalent (94.0%). Femoral hematoma was the most frequent complication (0.9%).
Conclusions: The patients who underwent surgery were predominantly male, older, hypertensive, and required urgent procedures, mostly for ST-segment elevation acute coronary syndromes, with very low rates of complications.
