title: [Myocardial infarction in patients with arterial hypertension. Changes in the creatine kinase MB isoenzyme activity in relation to myocardial hypertrophy].
abstract: The aim of the study was to investigate the relationship of arterial hypertension coexisting with myocardial hypertrophy to the infarct size evaluated by serial CK-MB measurements. The group of 98 patients (72 males and 26 females) with the first Q-wave infarction was selected from 137 patients admitted to I Clinic of Cardiology of Poznan Medical School with acute myocardial infarction (AMIO). Age of the patients ranged from 35 to 82, mean 60 years. Time from the onset of symptoms to admission to the hospital varied from 1 to 8 hours, mean 4. Enzymatic tests were performed on admission, every 4 hours during the first 24 hours, every 6 hours during the second and the third day and every 8 hours during the 4th and the 5th day. Anterior infarction was diagnosed in 46 patients and inferior infarction in 52 patients. The type of CK-MB curve, maximal CK-MB activity and the mass of necrotic tissue was evaluated for every patient using Sobel formula modified by Norris. Total mass of the left ventricle was calculated from echocardiographic measurements (2-D and M-mode) and the ratio of LV mass per square meter of the body surface was was calculated according to Horton's formula. The subgroup of 44 patients (25 males and 19 females) with the history of hypertension was selected. Ophthalmic examination revealed angiopathic changes of I and II grade K-W. This group, as compared to remaining patients with AMI was characterised by higher left-ventricular mass (198.0 +/- 28.6 vs 151.0 +/- 16.9 respectively).(ABSTRACT TRUNCATED AT 250 WORDS)
