FEATURES OF AMBULATORY ECG AND BLOOD PRESSURE MONITORING IN PATIENTS OF DIFFERENT AGE WITH ANEURISM OF ASCENDING PART OF AORTA

Factors contributing to the occurrence of an aneurism of the ascending aorta (AAA) are sufficiently understood, they are different in younger and older patients. However, factors associated with uncomplicated aortic aneurism, especially among young people, as well as predictors of progressive or complicated course of an aortic aneurism, which may be to forecast each individual patient, remain controversial and require further study.

Objective. To determine the features of the results of ECG daily monitoring, blood pressure and determination of heart rate variability (HRV) in patients of all ages diagnosed with AAA.

Materials and methods. 154 patients were examined with the expansion of the root and/or ascending aorta over 40 mm according to the echocardiographic study. Patients were divided into 4 categories by age: 18–29; 30–44; 45–59; 60–74 years old.

Instrumental examination methods: echocardiography, ECG, monitoring ECG and blood pressure, determination of HRV.

Results and discussion. Patients of different age groups were recorded various changes of daily profile of arterial pressure. Over all prognostically significant deterioration in performance occurred in groups with dominant acquired cardiovascular diseases (hypertension and ischemic heart disease) whereas younger patients were defined less change, mainly performance variability of blood pressure in a normal night lowering blood pressure.

In all age groups from AAA there were abnormal heart rhythm and conduction, the extent of which depended on organic myocardial injury and the severity of functional impairment and to some extent on age.

Conclusion. In patients with AAA infringement vegetative balance, mainly towards hypersympathycotonia, as it was observed in the majority of violations daily profile of blood pressure, but more substantial prognostic effects expected in a group of senior patients. It is given the direct relationship between aortic aneurism with blood pressure, which can accelerate the destabilization of aneurism course.

The perspective is to further examine the significance of violations in predicting the course of complications and AAA.
