ACTUAL PROBLEMS OF ARTERIAL HYPERTENSIONS PATHOGENESIS, CLINICS AND TREATMENT

V. M. Haroutyunian

Results of invrstigations, conducted by collaborators of Internal Diseases Department N2, Department of Diagnostics of Yerevan State Medical University, laboratory of clinical biochemistry with chronobiologist from SII of Cardiology, RMC "Armenia" Republican (dispansary) endocrinological dispansary, presented in this book, concern different actual aspects of essential and secondary arterial hypertension.
Here presented interesting data of epidemiological investigations, concerning spread of AH in stress-groups of the RA population. High frequency of AH presence among refugees from Azerbaijan is revealed. These results point out necessity to conduct special mass examination among these groups of RA population.
Chronobiological method is new and prospective direction in diagnostics of essential hypertension (EH). BP level chenges in patients with EH are under the influence of biorythmological regularity. Biorythmological investigations in patients with EH are very actual, thet's why methodical basis of chronodiagnostics have to be outlined because of great importance for the furder effective curative and preventive measures in dynamics, and also for prognostication of possible complecations in patients with EH.
Series of investigations are devoted to the comparative study of ultrasound scanning, reontgenocontrast methods, radioisotope renography, scintigraphy and CT properties in diagnostics of different nefrogenic hipertension forms. Authors defined that ultrasound renography allows to discover renal changes in 86,1% of cases and make a sure diagnosis in 64%. High informative valae and absence of contradications give us a reason to recomend this method for wide use not only in special medical institutions, but also in the system of practical Public Health.
Some works in this book concern pathogenesis, structural and functional heart reorganization and changes of GIT in patients with AH. We have to take into account ways of heart reorganization during adaptation for further prognosis and correct estimation of adaptation mechanisms of the heart in patients with AH, and also to control efficacy of antihypertensive therapy for remodelling of left ventricle hypertrophy and restoration of functional heart condition.
In works, devoted to pathogenesis of GIT disturbances in patients with EH, presented new, not traditional ideas about frequent affection of GIT due to hypertension. Pure blood supply in tissues, especially during paroxysm, has important role in pathogenesis of noted digestion disorders. These facts have to be used for preventive measures and theraphy of GIT disturbances in patients with EH.
Two works are devoted to the pathogenesis of AH in patients with FMF and amyloidosis. First work concerns causes of AH absence in patients with FMF during paroxysm, despite high level of sympathomimetic amines in blood. Mechanisms of AH in patients with amyloid dystrophy of kidneys and causes of AH absence with the presence of endent ischemia of both kidneys, caused by amyloid accumulation, are discussed in second work. Authors suppose, that hypertension and especially hypotension in patients with amyloidosis is caused by extrarenal factors, in particular by amyloid distrophy of endocrine system and liver condition.
Interesting data about hemorheological effects of Cardil (diltiazem) are presented in works, devoted to problems of AH therapy.
Some works, concerning chronoeffects of antihypertensive remedies, in particular clonidine and chronobiological reactions of kidneys in patients with chronic glomerulonephritis and AH, are very interesting. Authors convince, that time factor, physiological biorhythms of organism are to be taken into account while using pharmacological remedies, that allowsbiorhythms of organism are to increase efficacy of therapeutic influence in doses without adverse reactions.
Two works are devoted to the pharmacotherapy of AH by propranolol and renitec.
Thus, results of different investigations, conducted in different scientific groups, concerning actual aspects of AH, are presented in this book. Investigative work is to be continued and new data, acquired during that process, having theoretical and practical interest, are to be presented in the next book, devoted to not solved problems of AH.
