Relationships between Left circumflex artery (LCX) and Left anterior descending (LAD) involvements and calcification in patients with Coronary heart disease(CHD): a cross-sectional study

Abstract

Abstract Background This study aimed to investigate the relationships between LM, LAD, and LCX lesions and calcification in patients referred to Imam Khomeini Hospital, Medical, and Research center (Tehran, Iran). Methods The present study was an applied, cross-sectional, and observational study conducted on hospitalized patients suffering from coronary heart disease (CHD). By non-random sampling, 50 CHD patients who met the inclusion criteria were selected. CT angiography and MRI results were investigated, and field data collected by checklists were analyzed in IBM SPSS Statistics v. 13.00. Results There was no relationship between LM involvement and calcification, with 80% sensitivity and 44% specificity in the diagnosis of LM involvement. By contrast, LAD involvement was significantly correlated with calcification, with 77.8% sensitivity and 83.3% specificity in diagnosing LAD involvement. Likewise, a significant association was observed between LCX involvement and calcification, with corresponding LCX involvement diagnosis sensitivity and specificity values of 72.2% and 91.7%, respectively. Conclusion There was a significant correlation between LAD/LCX and calcification; However, there was no meaningful connection between LM and calcification.
