Myocardial infarction was associated with two properties for the s-block element models and none for the transition metal ion models: ion mass (AN) and oxidation energy (AN/[DELTA]IP).
These observations, along with the finding that associations of myocardial ischemia and myocardial infarction were observed primarily for s-block elements (Table 3), suggest a common mechanistic pathway for both outcomes among the metal ions examined.
