Abstract:

Objectives: Several risk scoring systems have been validated for cardiovascular risk prediction and prognosis. Periarterial adipose tissue intima media adventitia (PATIMA) index combining carotid intima media thickness (CIMT), carotid extra media thickness (CEMT), cardiac epicardial fat thickness (EFT), and body mass index (BMI) are related to coronary artery disease (CAD). Materials and Methods: One-hundred-twenty-four patients were categorized as low synergy between percutaneous coronary intervention with taxus and cardiac surgery (SYNTAX) (<22) (n=84) or high SYNTAX (≥22) (n=40) score groups. Association of PATIMA index and its components with SYNTAX score were analyzed. Results: CIMT, CEMT, BMI, EFT, and PATIMA index were not significantly different between groups. SYNTAX score was not significantly correlated with traditional CVS risk factors (diabetes, hypertension, hyperlipidemia, smoking, age). There was a significant correlation between the PATIMA index and age (r=0.308, p=0.001) but not with other risk factors. Age was significantly correlated with CIMT (r=0.289, p=0.001) and EFT (r=0.208, p=0.02) but not with CEMT (r=0.091, p=0.313). There was a significant correlation between CIMT and CEMT (r=0.414, p<0.001) and between CIMT and EFT (r=0.267, p=0.004). Conclusion: We have found that the recently described PATIMA index and its components, CIMT, CEMT, and EFT are not associated with the severity of CAD assessed by the SYNTAX score. Furthermore, they have not correlated with classical risk factors apart from age.
