Previous issue date: 2015-03-27 / Objectives: To identify the variables related to morbidity and risk factors for
death of patients that undergo to urgent myocardial revascularization surgery.
Method: Historical cross sectional study. It included 232 patients aged ?18
years old that underwent to isolated myocardial revascularization surgery, with
or without cardiopulmonary bypass. Those surgeries were urgents and were
adopted as emergency measures. It happened from January 1996 to December
2014. The total of revascularization myocardial surgeries carried out in this
period were 3772
Results: The frequency of death observed in this sample was 117 (50.4%).
Multivariate analysis identified as risk predictors: age ?65 years old (OR: 2.34;
95% CI 1.35 to 5.27; P = 0.007), congestive heart failure class III and IV (OR: 2,
67, 95% CI 1.35 to 5.28; P = 0.005), cardiopulmonary bypass time> 90 minutes
(OR: 2.52, 95% CI 1.21 to 4.17; P = 0.001), cardiogenic shock (OR: 3.47; 95%
CI 1.70 to 7.07; P = 0.001), acute myocardial infarction (OR: 2.73, 95% CI 1.25
to 5.94, P = 0.011), bleeding (OR: 3.06, 95% CI 1.00 to 9.37; P = 0.049).
Conclusion: Age, chronic obstructive pulmonary disease, class III and IV of
congestive heart failure, cardiopulmonary bypass time, cardiogenic shock,
acute myocardial infarction and bleeding they were independent predictors of
in-hospital mortality in patients that undergo to myocardial revascularization
surgery. / Objetivos: identificar as vari?veis relacionadas ? morbidade e os fatores de
risco para o ?bito de pacientes submetidos ? revasculariza??o do mioc?rdio de
urg?ncia e emerg?ncia.
M?todos: Estudo de coorte hist?rica. Inclu?dos 232 pacientes com idade ?18
anos, submetidos ? cirurgia de revasculariza??o do mioc?rdio isolada, com ou
sem uso de circula??o extracorp?rea, em car?ter de urg?ncia e emerg?ncia, de
janeiro de 1996 a dezembro de 2014, de um total de 3772 cirurgias de
revasculariza??o do mioc?rdio realizadas neste per?odo.
Resultados: A frequ?ncia de ?bito observada nesta amostra foi de 50,4% (117
pacientes). A an?lise multivariada identificou como preditores de risco para
mortalidade: idade maior que 65 anos (OR: 2,35; IC 95% 1,27?4,35; P= 0,007),
insufici?ncia card?aca congestiva classe III e IV (OR: 2,67, IC 95% 1,36?5,28;
P= 0,005), doen?a pulmonar obstrutiva cr?nica (OR: 2,49; IC 95% 1,21?5,11;
P=0,013) e tempo de circula??o extracorp?rea maior que 90 minutos (OR: 2,52,
IC 95% 1,22?4,17; P= 0,010).
Conclus?o: Idade, doen?a pulmonar obstrutiva cr?nica, classe III e IV da
insufici?ncia card?aca congestiva, tempo de circula??o extracorp?rea, foram
preditores independentes de mortalidade intra-hospitalar de pacientes
submetidos ? cirurgia de revasculariza??o do mioc?rdio de urg?ncia e de
emerg?ncia.
