[Silent myocardial ischemia in patients with essential hypertension].
Holter monitoring was performed in 61 patients with essential hypertension. Painless, silent ST segment depression was found in 34 patients. Exercise myocardial scintigraphy indicated the occurrence of transient perfusion defects without abnormal clearance (Group 1) and those with abnormal clearance (Group 2). The patients from Group 1 showed more severe myocardial hypertrophy, higher platelet aggregation, coronary atherosclerosis was detected in 1 case. The patients from Group 2 exhibited less myocardial hypertrophy, lower platelet aggregation. Coronary atherosclerosis was revealed in 4 cases. The patients from the two groups had elevated plasma norepinephrine levels at the onset of silent myocardial ischemia.
