Figure 2 (A) Shows that end-diastolic volume increased significantly and progressively and in nonsurvivors more than in it did in survivors. Left ventricular ejection fraction was decreased in nonsurvivors (B). Stroke volume index increased in survivors while it was depressed in nonsurvivors except at four weeks after infarction (C). (D) Shows that QTc duration decreased at and after 0.5 years after myocardial infarction in survivors but increased in nonsurvivors. QTc dispersion was decreased in survivors versus nonsurvivors (E). Lown score in survivors remained unchanged over time (F). Lown score significantly increased in nonsurvivors. Lown score 1 to 7 denotes: Lown grade 0; I; II; IIIa; IIIb; IVa; IVb. Values are mean ± SEM. The horizontal dashed lines indicate the upper (A,D,E) or lower (B,C) limit of normal for the respective value.
