[Emergency catheterization in a coronary intensive care unit. The diagnostic and therapeutic implications].
OBJECTIVE: to evaluate the diagnostic and therapeutic role of emergency hemodynamic studies, in the coronary intensive care (UCI). STUDY DESIGN: Retrospective study of--patients (P) submitted to emergency catheterization. PATIENTS: 183 P (152 M and 31 F), mean age 56 +/- 11.5 years, admitted to UCI of Hospital Santa Marta and who had cardiac catheterization performed, between October 88 and November 92. METHODS: Patient clinical files were reviewed. We considered the reasons for emergency cardiac catheterization; final diagnosis; complications in the first 24 hours; catheterization role in the therapeutic orientation. RESULTS: Reasons for hemodynamic study were: coronary artery disease (CAD) in 127 P (69%); aortic dissection in 33 P (18%); valvular disease in 19 P (10%) and other in 4 P (3%). Clinical diagnosis was confirmed in 92% and changed in 8% by hemodynamic study results. Left main coronary artery disease was diagnosed in 6.5% of CAD patients. Coronary artery disease was excluded in 5 P with previous CAD diagnosis, in 19 P with aortic dissection and in 11 valvular patients. 32% of P were sent to emergent surgery: 93% ascending aortic dissection and 20% of CAD, 76% of valvular disease. The hemodynamic study was decisive in the therapeutic option of myocardial revascularization in 77% of P with CAD: 39 emergent PTCA (31%), 13 primary (33%) and 14 P oriented to elective PTCA (11%); 26 emergent surgery and 19 P oriented to elective surgery (15%). The emergency cardiac catheterization mortality rate was 0.5%, and the morbidity 2.7%. CONCLUSIONS: The contribution of Hemodynamic Department to UCI was decisive in the diagnostic and therapeutic orientation of critical patients.
