Relationship between CANLPH score and in-hospital mortality in patients undergoing coronary artery bypass grafting.

Aim: To evaluate the CANLPH score in in-hospital mortality after coronary artery bypass grafting. Materials & methods: The 999 patients were included in this retrospective cohort study. Neutrophil/lymphocyte ratio, C-reactive protein/albumin ratio and platelet/hemoglobin ratio were determined and the CANLPH score was calculated as the sum score of 0 or 1 by the cutoff in each ratio. Results: Twenty-five patients who reached the primary end point were defined as the mortality group and the remaining as the nonmortality group. The CANLPH score was noninferior to the European System for Cardiac Operative Risk Evaluation II in receiver-operating characteristic curve analysis with difference between AUC: 0.0162, standard error (SE): 0.0394, z statistics: 0.682 and p = 0.494. Conclusion: The CANLPH score may be more appropriate in assessing the risk of in-hospital mortality after coronary artery bypass grafting.

Lay abstract Mortality, morbidity and complications of coronary artery disease depend largely on inflammatory processes. The CANLPH score, a combination of three different ratios, can better determine inflammation. We aimed to evaluate the CANLPH score in in-hospital mortality after coronary artery bypass grafting. The 999 patients were classified into two groups according to the primary end point. Twenty-five patients (2.5%) who reached the primary end point were defined as the mortality group and the remaining 974 patients as the nonmortality group. The multivariate logistic regression analysis showed that the European System for Cardiac Operative Risk Evaluation II, neutrophil/lymphocyte ratio, platelet/hemoglobin ratio and the CANLPH score were independent predictors of primary end point after coronary artery bypass grafting. The CANLPH score may be more appropriate than neutrophil/lymphocyte ratio, C-reactive protein/albumin ratio and platelet/hemoglobin ratio in assessing the risk of in-hospital mortality after coronary artery bypass grafting.

Relationship between blood viscosity and no-reflow phenomenon in ST-segment elevation myocardial infarction performed in primary percutaneous coronary interventions.

Background: This study aimed to analyze the associations between no-reflow (NR) phenomenon development and whole-blood viscosity in patients with ST-elevated myocardial infarction. Methods: A total of 217 patients with ST-elevated myocardial infarction were included. whole-blood viscosity values were assessed using hematocrit and total protein values, and low shear rate (LSR) and high shear rate (HSR) were calculated. Results: The average LSR and HSR values of the study group were significantly higher than the control group (p < 0.001). Multivariate logistic regression analysis showed that both HSR (odds ratio: 4.957; p < 0.001) and LSR (odds ratio: 1.114; p < 0.001) were independent predictors for NR development. Conclusion: This study found that increased blood viscosity was an independent predictor for NR development.

Lay abstract Following a heart attack, surgeons can attempt to repair the damage using a procedure called a percutaneous coronary intervention. In some cases, blood flow does not return to the heart tissue as expected ('failure of reperfusion') after this procedure, which is known as the no-reflow (NR) phenomenon. In this study, the researchers investigated whether there was a link between patients who had experienced a type of heart attack called an ST-elevated myocardial infarction (STEMI) and developed NR, and the viscosity (thickness) of their blood. The researchers looked at the viscosity of whole-blood samples from 98 STEMI patients with NR and 119 control individuals matched for age and gender. They found that whole-blood samples could be used to predict the likelihood of a STEMI patient experiencing NR.

High-sensitivity cardiac troponin T predicts nondipper hypertension in newly diagnosed hypertensive patients.

The increased prognostic accuracy of the high-sensitivity cardiac troponin T (hs-cTnT) assay vs the conventional cTnT assay has recently been reported in hypertensive patients. The authors aimed to investigate the significance of serum hs-cTnT marker for prediction of nondipper hypertension (HTN) in hypertensive patients. A total of 317 patients with newly diagnosed HTN were studied. The patients were divided into two groups: 198 dipper hypertensive patients (mean age, 51.7 ± 5.1 years) and 119 nondipper hypertensive patients (mean age, 53.4 ± 7.6 years). Hs-cTnT and N-terminal pro-brain natriuretic peptide (NT-proBNP) were measured in all patients. hs-cTnT and NT-proBNP were independent predictors for nondipper HTN (P<.05 for all). The cutoff value of hs-cTnT obtained by the receiver operator curve analysis was 7.55 ng/L for the prediction of nondipper HTN (sensitivity: 79%, specificity: 70%; 95% confidence interval, 0.769-0.860; P<.001). In patients with HTN, higher serum concentration of hs-cTnT even within normal range is an independent predictor of nondipper HTN.
