Also recorded are the results of coronary catheterization including coronary anatomy and left ventricular ejection fraction, procedures done at the time of initial catheterization and events thereafter (percutaneous coronary intervention (PCI), coronary artery bypass grafting (CABG) and death).
However, using verapamil/diltiazem did not provide additional improvement of left ventricular ejection fraction post procedure (at 7 days, WMD, 0.1; 95% CI, −2.43 2.63; P = 0.94; at 30 days, WMD, 0.42; 95% CI, −2.09 2.92; P = 0.75).
Patient-level characteristics in the registry included: age, gender, the New York heart association (NYHA) class, urgency of procedure, ejection fraction estimate, lipid-lowering treatment (hypercholesterolaemia), preoperative dialysis, previous cardiac surgery, procedure type, inotropic medication (inotropes), peripheral vascular disease, and body mass index (BMI) [ 34].
The current data concurs with previous reports showing that the incidence of CSA-AKI increases with patient-related risk factors such as previous impaired renal function, diabetes, low left ventricular ejection fraction, or procedure-related risk factors such as need for urgent surgery, length of cross-clamp time, administration of aprotinin, and red blood cells transfusion [ 17].
Demographic data, preoperative left ventricular ejection fraction, and procedure-related data were comparable between the groups (Table 1).
Among the pre- and intraoperative clinical variables predictive of readmission in this model, age, lung disease, left ventricular ejection fraction, and surgical procedure have been reportedly associated with readmission in previous studies [ 6- 9].
a. covariates: age, gender, race, education, household income, marital status, depressive symptomatology (CESD), ejection fraction, invasive cardiac procedures.
All data analysis was carried out using the Stata 10.1 software [ 37]. a. covariates: age, gender, race, education, household income, marital status, depressive symptomatology (CESD), ejection fraction, invasive cardiac procedures.
Covariates including race, education, marital status, ejection fraction category, and invasive procedure were consistently non-significant influences on both study outcomes when including either SCQ or CCI comorbidity measures.
Matching variables included Parsonnet score, low left ventricular ejection fraction, age, sex, bypass time, procedure type, CABG only or other procedures, and perioperative intraaortic balloon pump use.
