Relationship between extent and complexity of coronary artery disease and different left ventricular geometric patterns in patients with coronary artery disease and hypertension

Özet

Objective: The relationship between severity of coronary artery disease (CAD) and left ventricler (LV) hypertrophy in hypertensive patients iswell known. However, the association between the extent and complexity of CAD assessed with SYNTAX score (SS) and different LV geometricpatterns has not been investigated. We aimed to investigate the association between SYNTAX score and different LV geometric patterns inhypertensive patients.Methods: The study had been made in our clinic between January 2013 and August 2013. We studied 251 CAD patients who had hypertensionand who underwent coronary angiography (147 males, 104 females; mean age 61.61±9.9 years). Coronary angiography was performed based onclinical indications. SS was determined in all patients. Echocardiographic examination was performed in all subjects. Four different geometricpatterns were determined in patients according to LV mass index (LVMI) and relative wall thickness (RWT) (Groups: NG- normal geometry, CRconcentric remodeling, EH- eccentric hypertrophy, and CH- concentric hypertrophy). Biochemical markers were measured in all participants.Results: The highest SS values were observed in the CH group compared with the NG, CR, and EH groups (p<0.05 for all). Also, the SS values ofthe EH group were higher than in the NG and CR groups (p<0.05 for all). Multivariate linear regression analysis showed that SS was independently associated with LV geometry (β=0.316, p=0.001), as well as age (β=0.163, p=0.007) and diabetes (β=-0.134, p=0.022).Conclusion: SYNTAX score is independently related with LV geometry in hypertensive patients. This result shows that LV remodeling is parallelto the increase in the extent and complexity of CAD in our study patients.
