Comparison of Some Parameters in Estimating In-Hospital Mortality Risk in Patients Undergoing Open-Heart Surgery
(NLM (Medline), 2023) Atabey, R.D.; Şahinalp, Ş.
OBJECTIVE: Despite accumulating evidence showing the importance of various scoring systems in predicting preoperative mortality rates among patients who are undergoing open cardiac surgery, the prediction of in-hospital mortality is still limited. This study aimed to investigate the contributing factors associated with in-hospital mortality in patients who undergo cardiac surgery. PATIENTS AND METHODS: All patients, aged 19 to 80 years, who underwent cardiac surgery between February 2019 and November 2020 at our tertiary healthcare institute were analyzed retrospectively. Demographic details, transthoracic echocardiography data, operation-related details, cardiopulmonary bypass time and laboratory measurement results were retrieved from the institutional digital database. RESULTS: Data was available for a total of 311 subjects whose median age was 59 (52-67) years, and 65% of which were male. Among these 311 subjects, 296 (95%) were successfully discharged; however, in-hospital mortality was observed in 15 (5%) patients. Multiple logistic regression analysis revealed that low ejection fraction (p=0.049 and p=0.018), emergency surgery (p=0.022), low postoperative platelet (p=0.002) and high postoperative creatinine (p=0.007) were the most significant risk factors of mortality. CONCLUSIONS: In conclusion, in a population of subjects undergoing cardiac and thoracic surgery, the in-hospital mortality rate was 4.8%. Left ventricular ejection fraction (LVEF) <40%, emergency surgery, postoperative platelet count and postoperative creatinine were significant risk factors for mortality.
Containment Measures Established During the Covid-19 Outbreak and Its Impact on Lipid Profile and Neutrophil To Lymphocyte Ratio
(Verduci Editore s.r.l, 2020) Aladağ, N.; Şipal, A.; Atabey, R.D.; Akbulut, T.; Asoğlu, R.; Özdemir, M.
OBJECTIVE: Almost all countries announced social restrictions and distancing measures which could unintentionally lead to a decline in admissions to hospital for acute disorders other than signs of pneumonia. We aimed to evaluate lipid profile, neutrophil to lymphocyte ratio (NLR) and cardiovascular admissions to the coronary care unit (CCU) of a tertiary center in Turkey during the COVID-19 era and to compare these results with admissions in the same time interval of the previous year. MATERIALS AND METHODS: We retrospectively analyzed CCU admissions due to new-onset atrial fibrillation, ST-elevation myocardial infarction, non-ST elevation acute coronary syndrome (NSTEACS) and acute heart failure during the COVID-19 outbreak and the same time interval of the past year. Laboratory measurements including lipid profile and NLR values were retrieved from the institutional digital database. RESULTS: Compared to the same time interval of 2019 (March-April, 2019), the number of patients admitted to the CCU with acute cardiovascular disorders (atrial fibrillation, STEMI, NSTEACS and acute heart failure) were lower in the COVID-19 period. The levels of NLR, total cholesterol, and low-density lipoprotein (LDL) cholesterol were significantly higher and high-density lipoprotein (HDL) cholesterol was significantly lower in subjects admitted to the CCU during March-April 2020 compared to subjects admitted in March-April 2019. CONCLUSIONS: Our findings show that subjects admitted to the CCU in the COVID-19 era have an unfavorable lipid profile and elevated NLR compared to those admitted in 2019. These patients appear to be at high risk for future cardiovascular events. © 2020 Verduci Editore s.r.l. All rights reserved.
Which Is More Effective in Determining the Risk of Mortality and Complications After Coronary Artery Bypass Graft Surgery; Body Mass Index or Albumin
(Yuzuncu Yil Universitesi Tip Fakultesi, 2023) Atabey, R.D.; Şahinalp, Ş.
Preoperative risk analysis is important in predicting postoperative outcomes in patients undergoing cardiac surgery.These analyzed risk factors influence both the mortality and the morbidity results of coronary artery bypass graft (CABG) surgery. The aim of this study is to emphasize that the serum albumin value is a predictor of survival during the preoperative period for the patients that we prepared for surgery, and to indicate whether body mass index (BMI) is as valuable as albumin in predicting survival and postoperative period results. This study included patients who underwent CABG surgery between 2019-2020 at the Cardiac Surgery Center. Patient’s demographic information and all laboratory data were collected. Patients were grouped according to BMI and serum albumin values. Descriptive statistics for the continuous variables were presented as Mean, Standard deviation while count and percentages for categorical variables. A total of 174 patients, who underwent CABG surgery were included in the study.While postoperative complications were seen in 3.2% of patients with high BMI (>30 kg/m2), these complications did not develop in patients with low BMI (<20 kg/m2) (P=0.034).Patients who have serum albumin levels below 2.5g/dL are 22 times more likely to exitus than patients who have normal albumin levels (p=0.001, OR=22.246) whereas patients with normal BMI, obese patients have 16 times higher risk of exitus after bypass (OR=15.952) When we compare albumin and BMI, more extensive studies are needed to determine whether low serum albumin or increased BMI can independently predict the risk factors for poor short-term surgical outcomes. © 2023, Yuzuncu Yil Universitesi Tip Fakultesi.
