Simultaneous co\-existence of TIMI flow grade<2 in at least one RVB, and distal RPD embolization predicted the presence of RVI with the good sensitivity and specifity \(AUC 95 CI 0,97 \(0,94\-1\) \(OR=290, 95% CI\:28 to 2994, p<0,001\;OR =1553, 95% CI\:3 to 25771, p<0,001\) respectively. Group of 48 patients with RVI was divided into two groups\; one with small RVI and the second with large RVI, based on the median of RVIS \(Right Ventricular Infarct Size defined as RV_LE mass\/RVmass \*100%\), In univariate logistic regression analysis taking into account preprocedural, periprocedu and postprocedural factors affecting presence of RVI, the only two postprocedural factors which determined RVIS, were distal RPD embolization \(OR=3,34 \(95% CI 1,01\-11,1,p=0,049\) and RVBI \(OR= 41,84 \(95% CI 2,13\-823,3\; p=0,001\). Multivariable logistic regression analysis revealed RVBI as the only independent predictor of infarct size \(OR = 24,2 \(95% CI 1,12\-523,9\; p=0,004\). The median value for RVEF in group with large RVI was 43% \(min. 27%\-max.65%\). The median value for RVEF in group with small RVI was=54% \(41% \-73%\),\(p <0.001\) Values of median for the groups with small RVI, and RVI \(\-\) did not differ from each other statistically_significant \(p = 0.43\). As_a result_of the hierarchical multivariate logistic regression taking into account_above mentioned preprocedural variables, a model that best predicted the presence of elevation ST ≥ 1 mm in V4R was TIMI<3 flow in at least_one RVB, if there_were no PA in the period of 24 h before MI \(OR = 6,51, 95% CI\: 2,37 to 17,93, p<0,001\; OR = 0,38, 95% CI\: 0,15 to 0,98, p<0,04 respectively\). Reversible RV ischemia, visible_as the_presence of elevation ST ≥1 mm in V4 R was present in 83 \(73%\) cases which was in mild agreement with the CMRI LE\- findings for RVI which revealed RVI necrosis in 48 \(42%\) patients.Conclusions\:1. The optimal_outcome of PPCI, with_successful reperfusion both the main RCA, as well as all RVB’s with a diameter of ≥ 1 mm, effectively protects against RV wall necrosis, regardless of baseline clinical and angiographic conditions."]
