Assessment of Selected Baseline and Post-PCI Electrocardiographic Parameters as Predictors of Left Ventricular Systolic Dysfunction after a First ST-Segment Elevation Myocardial Infarction

  Figure 1. LVSD prevalence 6 months after STEMI according to terciles of QRS duration (a) on admission and (b) post PCI. Median LVEF 6 months after STEMI according to increasing terciles of QRS duration (c) on admission and (d) post PCI. LVEF, left ventricular ejection fraction; LVSD, left ventricular systolic dysfunction; ms, milliseconds; PCI, percutaneous coronary intervention; STEMI, ST-segment elevation myocardial infarction.

  Figure 2. Predictors of LVSD occurrence after 6 months of follow-up according to the univariate logistic regression analysis: (a) demographic, clinical, angiographic and biochemical variables; (b) baseline electrocardiographic variables; (c) post-PCI electrocardiographic variables. BNP, B-type natriuretic peptide; CK-MBmax, maximal activity of isoenzyme MB of creatinine kinase; cTnImax, maximal concentration of troponin I; CI, confidence interval; IRA, infarct-related artery; LAD, left anterior descending artery; LVSD, left ventricular systolic dysfunction; ms, milliseconds; OR, odds ratio; PCI, percutaneous coronary intervention; STEMI, ST-segment elevation myocardial infarction; TIMI, thrombolysis in myocardial infarction score.

  Figure 3. Predictors of LVSD presence after 6 months of follow-up. The model was created using multivariate logistic regression analysis by adding all electrocardiographic variables to the demographic, clinical, angiographic and biochemical data. CI, confidence interval; IRA, infarct-related artery; LVSD, left ventricular systolic dysfunction; ms, milliseconds; OR, odds ratio; PCI, percutaneous coronary intervention; STEMI, ST-segment elevation myocardial infarction, TIMI, thrombolysis in myocardial infarction score.
