Electrophoretic HbA2 assessment in ischemic heart disease.

A series of fifty patients presenting ischemic heart disease are studied. As shown by the electropherogram, apart from the basic band of hemoglobin A2, an additional weaker band appears with a diffuse zone between them. The quantity of the entire HbA2-diffuse zone exceeds by 3.8 per cent the total hemoglobin. Its appearance is not attributed to abnormal hemoglobin or beta-thalassemia. With the passing of time its quantity shows a decrease, and within 3-6 days it disappears. Parallel to normalization of the hemoglobin profile the pain syndrome among patients with unstable stenocardia subsides, and stabilization of the patients with a history of myocardial infarction takes place.
