TI  - The association between left ventricular mass index and coronary collateral circulation in patients with chronic total occlusion
AB  - Objective: Left ventricular (LV) hypertrophy predisposes themyocardium to ischemia through several mechanisms. TheLV mass index (LVMI) is used as a readily available and reliablemeasurement of LV hypertrophy. The LVMI can alsobe used to evaluate LV remodeling. The hypothesis of thisstudy was that LV hypertrophy might augment coronary collateralizationin patients with chronic total occlusion (CTO) andthe aim was to research any association between LVMI andcollateral formation in CTO. As a secondary goal, specific LVgeometric types that might be associated with collateral presencewere also investigated.Methods: A total of 305 patients with CTO were included andcategorized into 4 groups based on Rentrop grade.Results: The LVMI demonstrated an incremental linear trendas the Rentrop grade increased. In the receiver operatingcharacteristic curve, the likelihood that a cut-off value of 100.1g/m2 would accurately differentiate patients with collateralsfrom those without collaterals was 75.8%, with 68.5% sensitivityand 68.6% specificity. A 1 gram/m2 increase in LVMIwas associated with a 7.5% greater likelihood of collateral development.In addition, compared with normal geometry, thepresence of eccentric hypertrophy was associated with 6.7times higher odds of the presence of coronary collaterals.Conclusion: The results of this study indicated that a greaterLVMI predicted coronary collateral presence. Furthermore,having an eccentric geometric type of hypertrophy increasedthe likelihood of coronary collaterals more than other geometries.This finding signified that in addition to LV wall thickness,the type of hypertrophy was also decisive in predicting collateralpresence.
