[Epidemiology of arterial hypertension and various characteristics of mineral metabolism among nomadic stock breeders in Tuva]. / Epidemiologiia arterial'noi gipertonii i nekotorye osobennosti mineral'nogo obmena u kochuiushchikh zhivotnovodov Tuvy.

To reveal cardiovascular abnormalities, a screening was made in Tuva, which covered 1481 nomadic stock breeders, 1041 settled natives and 1081 migrants. The incidence of arterial hypertension (AH) was 33.5% among the nomadic stock breeders and 17.2% among the settled Tuva habitants and migrants. No impact of obesity and dyslipoproteinemia on the incidence of AH was found in the nomadic stock breeders. There was a direct correlation between the incidence of AH and alcoholization and an inverse correlation between its incidence and smoking in nomadic stock breeders aged 50-59 years. The hairs from the nomadic stock breeders exhibited elevated levels of aluminium, chromium, manganese, iron, and vanadium, which is not attributable to higher levels of these compounds in the meat of domestic animals.

[Effect of the vertebral syndrome in cervical osteochondrosis on the course of I-IIA stage hypertension and cerebral electrical activity and hemodynamics]. / Vliianie vertebra'lnogo sindroma pri sheinom osteokhondroze na techenie gipertonicheskoi bolezni I-IIA stadii, bioélektri- cheskuiu aktivnos't i gemodinamiku mozga.

Examination included two groups of patients with I-IIA stage essential hypertension combined with cervical osteochondrosis: with and without the vertebral syndrome. It revealed significant polymorphism of clinical symptoms, more severe course of vascular pathology, disorders of cerebral hemodynamics with decreased pulse blood filling, increased tone of arterioles, venules and veins, signs of disturbances of venous outflow and features of bioelectric brain activity indicating dysfunction of the middle structures in patients with the vertebral syndrome of cervical osteochondrosis. Since the pathogenic significance of cervical osteochondrosis is mostly realized in the presence of the vertebral syndrome, therapeutic policy should involve both antihypertensive agents and measures that control vertebrogenic pathology as well as medicamentous correction of hemodynamic cerebral disturbances.

[Prevalence of ischemic heart disease and its risk factors among Tuva cattle-breeders]. / Rasprostranennost' ishemicheskoi bolezni serdtsa i faktorov ee riska sredi zhivotnovodov Tuvy.

A simultaneous comprehensive epidemiological survey of 1198 cattle-breeders was conducted in central and southern Tuva. CHD in men was diagnosed in 11.1%, in women in 24.0% (all of them aged 20 to 69). Changes in the end part of the ventricular complex were more common, particularly in women. Arrhythmia and angina of effort were very rare. Functional ECG tests (including propranolol, piridamole, bicycle ergometry) brought about negative results with relation to CHD. Positive correlation was shown between CHD prevalence and AH frequency, negative correlation--between CHD prevalence and smoking frequency. Rare excessive body mass and fat metabolic derangements probably accounted for the absence of correlation of these indices with CHD frequency. A high AH frequency was revealed in men (12.3%) and women (28.8%). Left ventricular hypertrophy was noted in 25.8% of men, of them raised BP was noted in 36.6% only; in women these figures were 12.7 and over 50%, respectively. Some peculiarities of the epidemiology of CHD and its risk factors in Tuva indicated a high frequency of noncoronarogenic myocardial pathology, rare occurrence of CHD, and low specificity of the Minnesota code criteria for the detection of this disease in the population under study.
