Aim: We aimed to answer the question of: are patients over 75
years of age associated with poor survival in combined operations?
and to identify independent risk factors that predict survival in patients
undergoing these procedures.
Methods: Data were collected prospectively from 476 patients
who underwent combined procedures at Kings College Hospital
between 1998 and 2004. Patients were divided into two groups,
group A: 341 patients under the age of 75 years and group B:
136 above age of 75 years. In-hospital mortality was used for survival
analysis. Statistical analysis was performed using Stata 6.
Results: Median age was 71 years (range 26–88). Three hundred
and twenty six (68%) patients were male. In addition to
the coronary grafting, 339 (71%) patients had operation on aortic
valve, 132 (27.7%) on the mitral valve, 5 (1%) on both valves and
1 (0.2%) on the tricuspid valve. The following were identified as an
independent predictors of in-hospital mortality; female sex (OR
3.193, CI 1.118–8.589, P =0.022), and emergency surgery (R
346.5, CI 27.282–4400.793, P = 0.043). |
