Abstract

Background: Ischemic heart disease (IHD) is the most common cause of mortality, and prompt treatment can be life-saving. Cardiogoniometry (CGM) is a noninvasive method that seems reliable for IHD diagnosis. This study aimed to determine the accuracy of CGM in IHD diagnosis in patients with suspected acute coronary syndrome (ACS), especially those with unstable angina or non–ST-elevation myocardial infarction (NSTEMI), whose diagnosis may be challenging.
 
Methods: This cross-sectional study was performed at Rajaie Cardiovascular Medical and Research Center, a tertiary public hospital. Forty-five patients with ACS in the emergency ward were enrolled. The patients underwent CGM about 24 hours before catheterization, and the results were compared with angiography as the gold standard for IHD diagnosis. The data were analyzed using the SPSS software and were reported separately for age, sex, and hypertension.
 
Results: The sensitivity and specificity of this method were 96.7% and 55.3%, respectively. The positive and negative predictive values were 80.6% and 88.9%, respectively.
 
Conclusions: CGM is a sensitive method for confirming or ruling out ACS. It is useful when the diagnosis is challenging, especially when ACS is suspected and electrocardiography or laboratory test results are unremarkable. Other studies are needed to confirm our conclusion. (Iranian Heart Journal 2023; 24(1): 39-44)
