Impact of age on the results of coronary artery bypass grafting.

As the average age of patients undergoing cardiac surgery is increasing, the effects of age on the incidence of postoperative complications and 30-day mortality after coronary artery bypass grafting were examined. The EuroSCORE and corresponding age-stripped EuroSCORE were calculated in 6,057 patients who underwent isolated coronary bypass between January 1996 and January 2002. Both EuroSCORE and age-stripped EuroSCORE exhibited a significant increase with age in the whole group of patients and in those who were alive 30 days after surgery.

[Impact of smoking on the results of coronary artery bypass surgery].

Background And Purpose: The proportion of patients undergoing coronary artery bypass surgery (CABG) with a history of smoking is increasing. The aim of this study was to examine the effect of smoking on outcomes following CABG.

Patients And Methods: 6,367 consecutive patients who underwent CABG between April 1997 and March 2003 were analyzed retrospectively.

[Impact of age on postoperative events and mortality in cardiac surgery].

Background And Objective: The number of "older" patients undergoing cardiac surgery is steadily increasing. In the year 2000, 37% of all patients who underwent a cardiac operation in Germany were > or = 70 years. Looking at data from our institution, we analyzed the impact of age on postoperative events and mortality in cardiac surgery.

Current determinants of operative mortality in 1400 patients requiring aortic valve replacement.

Background: Determinants of operative mortality after aortic valve replacement vary with a changing patient population due to advances in operative management and increasing life expectancy. In order to predict current groups of high risk patients, a statistically valid large study population base recruited over a short period of time is required.

Methods: Between January 1996 and June 2001, 1408 aortic valves were replaced in 1400 patients (572 of them with simultaneous coronary artery bypass grafting).

Creatinine clearance versus serum creatinine as a risk factor in cardiac surgery.

Background: Renal impairment is one of the predictors of mortality in cardiac surgery. Usually a binarized value of serum creatinine is used to assess the renal function in risk models. Creatinine clearance can be easily estimated by the Cockcroft and Gault equation from serum creatinine, gender, age and body weight.

Is age an independent determinant of mortality in cardiac surgery as suggested by the EuroSCORE?

Background: The proportion of older patients in cardiac surgery is continuously increasing. 37% of patients undergoing heart surgery in Germany in the year 2000 were 70 years of age and older. We have studied the role of age as a determinant of mortality in cardiac surgery in our institutional patient population.
