value calculated by the Kruskal-Wallis test for continuous variables and by the Chi-square test for categorical variables. Time in minutes from start of chest pain to complete revascularization. IRA = infarct related artery. LAD = left anterior descending artery. RCA = right coronary artery. LCX = left circumflex artery. ACE-inh. = angiotensin-converting-enzyme inhibitor. AT2 = angiotensin type 2 receptor. LV = left ventricle. Data are expressed as absolute numbers or mean ± SD.
