A Chinese scoring system for predicting successful retrograde collateral traverse in patients with chronic total coronary occlusion.

Background: Retrograde approach technique has been challenging in percutaneous coronary interventional treatment of chronic total occlusion (CTO) coronary disease. The present study endeavors to determine a novel Chinese scoring system for predicting successful collateral channels traverse via retrograde approach.

Methods: The demographic characteristics and angiographic characteristics of 309 CTO patient were analyzed by univariable and multivariable analysis for selecting potential predictors.

Admission high-sensitivity C-reactive protein levels improve the Grace risk score prediction on in-hospital outcomes in acute myocardial infarction patients.

Background: Acute myocardial infarction (AMI) is the main cause of death and disability in cardiovascular and cerebrovascular diseases. Both the Global Registry of Acute Coronary Events (Grace) score and high-sensitivity C-reactive protein (hs-CRP) were associated with prognosis in patients with AMI. However, whether the addition of the hs-CRP to Grace risk score could improve the predictive power of Grace risk score on the prognosis of patients with AMI is unclear.
