“…(23) In another study comparing the EuroSCORE II in a Turkish cohort of 428 patients, the model was shown to underestimate mortality risk for the entire cohort. (24) Our study cohort, though small, showed a similar pattern with the predicted mortality being underestimated in the entire cohort but overestimated in the lower risk AVR and MV repair groups. In addition, the EuroSCORE II had a better discriminatory ability for early mortality in the AVR group than the other sub-groups in our study.…”

There has been little change in the mortality from infective endocarditis, despite the diagnostic and therapeutic advances made in the last 25 years. The current in-hospital mortality rate for patients with IE is 15% -20%, with 1-year mortality approaching 40%. The morbidity associated with infective endocarditis includes: valvular incompetence, embolisation, cerebrovascular accidents and congestive heart failure which have influenced the surgical approaches to a great extent. Infective endocarditis is a significant problem in sub-Saharan Africa and is related to a high prevalence of rheumatic heart disease among the young indigent population. Africa has the highest burden of rheumatic heart disease contributing 17% -43% of all heart disease.

“…The differences between AUC of addES and the AUC of ESII in both examined groups were statistically significant (Table 4). In contrast to this data, the addES remained good in three studies performed by Kunt et al [9], Toumpoulis et al [17], and in a CABG cohort from Akgül et al [11]: AUC: 0.70 and 0.72, 0.992, respectively.…”

“…The mortality rate in our study was at the level of 5.21% and it did not differ with the background of other similar studies, in which this value ranged from 2.2% to 5.66% [8][9][10][11][12][13]. For our CABG patients, this value was 5.33%.…”

A b s t r a c tBackground: EuroSCORE is used to predict postoperative mortality in patients undergoing cardiac surgery. Its updated version was published in 2011. Aim:To assess whether EuroSCORE II (ESII) predicts more accurately postoperative mortality after cardiac surgery in comparison with additive (addES) and logistic EuroSCORE (logES). Methods:A total of 461 patients (aged 21-88 years, 63.4% of men) who underwent cardiac surgery (December 2010 -June 2011) were included into the prospective research. For each patient ESII, addES and logES were calculated. Accuracy, calibration, and clinical performance of these models were assessed with receiver operating characteristics analyses using the area under the curve and the Hosmer-Lemeshow test. Out of this population, a group of 300 coronary artery bypass grafting (CABG) patients (aged 42-85 years, 73% of men) was selected and statistically analysed using the same methods. Results:The mortality rate was 5.21%. Predicted mortality rates were as follows: addES 4.68%, logES 4.57%, and ESII 1.89%; the accuracy was: 0.589, 0.728, and 0.726, respectively. Only logES presented good predictive power (Hosmer-Lemeshow test: c 2 = 12.79, p = 0.12). In the CABG patients, the postoperative mortality rate was 5.33%. Predicted mortality rates were as follows: addES 4.69%, logES 4.59%, and ESII 1.88%; the accuracy was: 0.512, 0.691, and 0.687, respectively. In the Hosmer-Lemeshow test also logES presented good predictive power (c 2 = 10.72, p = 0.218). Conclusions:EuroSCORE II did not estimate mortality risk better in comparison to its previous versions, in the entire studied population or in the CABG patients. On the basis of the analysed data, it seems that the closest to the actual risk of death for the Polish population is the EuroSCORE logistic model. [1] is used to predict operative mortality in patients undergoing cardiac surgery. The scoring system was prepared using the most reliable and objective risk factors out of 97 risk factors collected from nearly 20,000 patients from 128 hospitals in eight European countries. All of the selected risk factors were divided into three groups: patient-related, cardiac-related, and operative-related factors. If

“…Later on, another scoring system by The Society of Thoracic Surgeons (STS) was described, and published [12]. STS scoring system which is more detailed relative to the EuroSCORE system has demonstrated its superiority over EuroSCORE in many cardiac surgery groups [13-15]. However clinical application of STS scoring system is very difficult.…”

OBJECTIVE:In this study, the effect of neutrophil-lymphocyte ratio (NLR), which is a recently developed inflammatory parameter, as an early stage mortality predictive marker on coronary artery bypass (CABG) patients of various age groups was examined.METHODS:Seventy eight patients under the age of 45 (Group 1) and 80 patients who were older than 45 (Group 2) randomly chosen from the patients who underwent isolated CABG surgery, were examined. The preoperative characteristics and NLRs were noted. The primary end point of the study was determined as all-cause in- hospital mortality.RESULTS:Mortality was observed in 2 patients in Group 1 and 11 patients in Group 2. The threshold value of NLR was 2,47 in the Receiver Operating Characteristic (ROC) curve in Group 1 and there wasn’t any significant correlation between preoperative NLR and mortality rates in the patients whose NLRs were above this curve. The threshold value was determined as 4.07 in Group 2 and there was a significant relation between preoperative NLR and mortality (p<0,01). No relation was found between NLR and mortality when all the examined patients were considered (p>0.05).CONCLUSION:NLR that can be easily calculated, can be used as a mortality predictor in the patients of advanced age who will undergo isolated CABG procedure.
