Appropriateness of angiography for suspected coronary artery disease
Abstract
The aim of this study was to assess the appropriate use of diagnostic catheterizations (DC) for the patients with suspected coronary artery disease performed in Iran. The Electronic Health Record System database and manual review of files were utilised to collect data between 2012 and 2014. Patients were categorized in three groups as appropriate, uncertain, and inappropriate usage of DC and the logistic regression was used to investigate the relationships between variables. One-quarter of the 2458 angiographies were rated as inappropriate, out of which 99% had no previous stress test. The rate of inappropriate DC between various hospitals were approximately the same. The regression showed that some risk factors (Sex, high cholesterol, smoking, chronic heart failure, renal failure, diabetes) were significantly associated with inappropriate rate.
