Journal Article 1 In the study by Colkesen et al. (2015), the researchers sought to identify the “predictors of in-hospital mortality in patients undergoing preoperative cardiac surgery by a single surgical team” in a single center. Open heart surgeries were performed on patients in the years 2010 to 2014. Those who required cardiopulmonary resuscitation before surgery had gone through the acute aortic dissection surgery, as well as a thoracic and aortic aneurysm surgical procedures,  were excluded in the study [1]. In the sample, there were 1367 patients where 109 underwent redo cardiac surgery, and the rest 1258 was the control group. This was a retrospective design, on the risk factors that were associated with in-hospital mortality among redo cardiac surgery patients while patient information was stored prospectively in a database [1]. The quantitative research was causal-comparative, where European System for Cardiac Operative Risk Evaluation (EuroSCORE) and postoperative atrial fibrillation (AF) predicted the in-hospital mortality [1]. The surgical techniques used were “cardiopulmonary bypass (CPB) (on-pump) with arrested heart (conventional CABG), on-pump with beating heart; and off-pump beating heart” [1]. For the redo cases there, were patients died because of cardiac and multisystemic causes or injury and this represents 4.6%. Postoperative (AF) and EuroSCORE were the significant predictors of hospital mortality. Identifying the predictors of in-hospital mortality is useful to determine those who are most likely to benefit from the preoperative cardiac surgery procedures.   The reoperation rate increases with age, and unlike before redo surgery is relatively safe. There were limitations in the study since the data were collected prospectively, and the study approach is retrospective, and the data was from a single center, which may affect the study’s conclusion. Journal Article 2 Preoperative Scorecards can predict and help assess the risk of in-hospital mortality following cardiac redo procedures [2]. The rate of reoperative coronary artery bypass grafting (CABG) is associated with a higher risk of worsening outcomes, but the incidence of the procedure has been declining in the US.  Out of the 17,645 patients who underwent t cardiac procedures in the years 1995 and 2010, 521 patients underwent redo procedures at the Queen Elizabeth II Health Sciences Centre in Canada the majority of the participants made (69.5%), and the patients were most likely to undergo the CABG  surgical procedure [2].  The data analyzed was perioperative to determine the mortality rate. The patients selected were non-random as long as they underwent redo cardiac surgery and they were anonymous as the researchers did not collect information that would help identify the participants specifically. In the quantitative study, the authors got data from the hos...
