Elevated plasma D-dimer and hypersensitive C-reactive protein levels may indicate aortic disorders.
D-dimer and C-reactive protein are of diagnostic and predictive values in patients have thrombotic tendency, such as vascular thrombosis, coronary artery disease and aortic dissection. However, the comparative study in these biomarkers between the patients with acute aortic dissection and coronary artery disease has not been sufficiently elucidated. ⋯ The patients with acute aortic dissection and aortic aneurysm may reflect the extensive inflammatory reaction and severe coagulopathies in the patients with acute type A aortic dissection, and thoracic aortic aneurysm in comparison to the coronary patients and healthy control individuals. The detections after onset in the patients with acute chest pain may help making a differential diagnosis between the aortopathies and ischemic heart disease. The scanty significance of the tissue biomarkers may preclude their diagnostic value in clinical practice.

Randomized Controlled TrialAssessment of noninvasive ventilation with two levels of positive airway pressure in patients after cardiac surgery.
The application of two levels of ventilation by positive pressure (BiPAP®) associated with conventional respiratory therapy (CRT) in postoperative periord of cardiac surgery may contribute to reduction of pulmonary complications. ⋯ Coronary artery bypass grafting leads to deterioration of respiratory function postoperatively, and the application of positive pressure ventilation (BiPAP®) may be beneficial to restore lung function more quickly, especially vital capacity, safely, and well accepted by patients due to greater comfort with the sensation of pain during the execution of respiratory therapy.

Controlled Clinical TrialTranscutaneous electrical nerve stimulation after coronary artery bypass graft surgery.
After cardiac surgery, patients have a limitation in respiratory muscle strength, which favors the appearing of pulmonary complications. ⋯ TENS has shown significant effectiveness in reducing pain, and the increase in respiratory muscle strength at first-day after CABG surgery.

Predictors of transfusion of packed red blood cells in coronary artery bypass grafting surgery.
Finding predictors of blood transfusion may facilitate the most efficient approach for the use of blood bank services in coronary artery bypass grafting procedures. The aim of this retrospective study is to identify preoperative and intraoperative patient characteristics predicting the need for blood transfusion during or after CABG in our local cardiac surgical service. ⋯ The identification of these risk factors leads to better identification of patients with a greater probability of using blood, allocation blood bank resources and cost-effectiveness use of blood products.
