Reperfusion Correlates and Clinical Outcomes of Right Ventricular Dysfunction in Patients With Inferior ST-Segment Elevation Myocardial Infarction Undergoing Percutaneous Coronary Intervention

We evaluated the relation between reperfusion indexes and right ventricular (RV) dysfunction in patients with inferior ST-segment elevation myocardial infarction (STEMI). We included patients with inferior STEMI undergoing percutaneous coronary intervention and right coronary artery as infarct-relat...

Zusammenfassung:	We evaluated the relation between reperfusion indexes and right ventricular (RV) dysfunction in patients with inferior ST-segment elevation myocardial infarction (STEMI). We included patients with inferior STEMI undergoing percutaneous coronary intervention and right coronary artery as infarct-related artery. Myocardial reperfusion was evaluated by Thrombolysis In Myocardial Infarction (TIMI) flow, TIMI frame count, myocardial blush grade, and ST-segment resolution. RV dysfunction was defined as tricuspid annular plane systolic excursion ≤16 mm in M-mode imaging. RV dysfunction was present in 58 of 141 patients (41.1%) and was more frequent in patients achieving suboptimal postprocedural TIMI flow grade (66.7% vs 36.7%, grades 0 to 2 vs 3, p = 0.01), TIMI frame count (63.2% vs 37.7%, ≥40 vs
