title: [Study of the effect of arterial hypertension on the status of left- ventricular myocardium based on thallium-201 scintigraphic data].
abstract: Functional relationship was examined between the parameters of myocardial perfusion, left ventricular myocardial mass, and complications developed in patients with coronary heart diseases concomitant with arterial hypertension. Examination was made of 102 patients with various natural history of arterial hypertension, of whom 53 had concomitant angina pectoris, myocardial infarction, congestive heart failure, sudden death, or rhythm disturbances. As "perfusion deficiency" progressed, the patients with complicated natural history of arterial hypertension were found to increase in number with higher left ventricular myocardial mass index. In patients with arterial hypertension, the critical hypertrophy phase in which the index of left ventricular myocardial mass was 110-120 gm2 was demonstrated to be followed by myocardial perfusion deficiency. If the myocardial mass index is 90 g/m2, it means a phase of compensatory hypertrophy, which shows higher myocardial perfusion.
