Evaluation of the coronary angiography results in patients referred to cardiac centers in Isfahan City, Iran

Abstract

Background: Diagnostic invasive coronary angiography is known as an important tool for identifying patients with obstructive coronary heart disease. Angiography performance is recommended in patients with high risk of ischemic heart disease. Methods: Coronary arteries angiography data of 1100 subjects from a large population of patients referred to four main heart disease centers in Isfahan city, Iran, were collected during 2016 January-March. Demographic information, cardiac noninvasive test results, body mass index (BMI), smoking habits, hypertension, diabetes mellitus and family background of ischemic heart disease were recorded in using a questionnaire. Data were analyzed using ANOVA and chi-square statistical tests in SPSS software to determine the association between angiography results and cardiovascular risk factors. Findings: In angiography, 40 of patients did not show any significant obstructive coronary disease and normal angiography was approximately two times more in women than men in the studied populations. 26 and 44 of subjects had a history of diabetes mellitus and hypertension, respectively. 19 of patients had past history of myocardial infarction (MI) and 21 had history of cigarette smoking. Most of the subjects (72) had overweight and obesity (BMI > 25). Non-invasive testing, including exercise test and heart scan, was performed in only 42.0 and 2.7 of patients, respectively. Conclusion: Due to significant economic cost of angiography for the national healthcare system, beside the importance of angiography performance in diagnosing coronary artery diseases, we recommend more studies to clear patient need to angiography. © 2017, Isfahan University of Medical Sciences(IUMS).
