[Cardiovascular disorders in case of acute gastrointestinal bleeding in patients with arterial hypertension].

AIM: To investigate the blood pressure changes and electrocardiogram parameters for the 1st day after acute gastrointestinal bleeding in patients with arterial hypertension. MATERIAL AND METHODS: Indexes of blood pressure monitoring and electrocardiogram in case of acute gastrointestinal bleeding in patients with arterial hypertension were studied. 45 patients with arterial hypertension and acute gastrointestinal bleeding, 63 patients in acute stage of bleeding without hypertension and 48 patients suffering from hypertension without gastrointestinal bleeding were studied. Parallel simple open controlled investigation included blood pressure monitoring and Holter monitoring. RESULTS: Circadian dynamics of blood pressure in patients with arterial hypertension on the background of gastrointestinal bleeding was noted by reduced variability and insufficient reduction of pressure at night. Diastolic pressure decreased in accordance with severity of blood loss. Holter monitoring revealed high incidence of supraventricular ectopic activity, sinus arrhythmia and significant elongation of the ventricular electrical systole.

[24-hour monitoring of electrocardiogram, arterial pressure, and psychovegetative disorders during acute peptic ulcer hemorrhage in patients with hypertensive disease].

65 patients with hypertensive disease (HD) and without it were examined in the acute period of gastroduodenal ulcer hemorrhage (UH) by 24 hour ECG monitoring, measurement of arterial pressure (AP), and evaluation of the severity of psychovegetative syndrome. Control groups comprised 20 patients with ulcer disease (UD), 28 with HD, and 12 with UD + HD. Patients of the latter group, similar to normotensive ones, suffered suppressed function of the sinus node in addition to functional changes in myocardium including a change of ST-T segment. Circadian rhythm of AD was unrelated to the presence and absence of HD. In both cases, blood loss was associated with anxiety-depressive condition and well-apparent ergotropic reactions. Patients with UD and HD had more expressed emotional and personality disorders associated with impaired vegetative response. Dippers had marked sympathetic activity at rest and in vegetative reactivity tests whereas non-dippers showed ergotropic effects in similar tests.
