ABSTRACT
OBJECTIVES: The direct correlation between Echocardiographic non-coronary calcium score (ECS) and lesion severity on invasive coronary angiography (ICA) is not reported. The aim of the present study was to find the correlation between ECS and Gensini score. METHODS: One hundred seventy patients aged ≥18 years posted for clinically indicated ICA were included. All the patients underwent standard transthoracic echocardiography. ECS and Gensisni scores were calculated. The primary outcome measure was to find a correlation of ECS with Gensini score, whereas the secondary outcome measure was to correlate ECS with traditional risk factors for coronary artery disease. The Chi-square/Fisher exact test was used to compare qualitative variables. Spearman's correlation analysis was used for assessing the correlation between ECS score and the Gensini score. Receiver-operating characteristic curve analysis was performed to detect the cut-off value of the ECS score. RESULTS: The correlation of total ECS with Gensini score was positive and statistically significant (r = 0.550, p-value < 0.0001). As ECS increased, the Gensini score increased. ECS value of >1 detected CAD with 56.5% sensitivity, 79.5% specificity. Eight-nine percent of patients who had ECS >1, had Gensini score ≥18, whereas 44.3% of patients who had ECS ≤1, had Gensini score ≥18. The patients with ECS >1 had significantly higher Gensini scores than the patients with ECS ≤1. CONCLUSIONS: The correlation of total ECS with Gensini score was positive and statistically significant.
