Color Doppler ultrasound imaging is an explorating method no harmful, no hemorrhagic with possibility of early diagnosis and accurate evaluation of injuries on vascular system in the pathology of lower extremity arterial occlusive disease.

To find prevalence of orthostatic hypotension (OH) in elder persons living in community, blood pressure was measured in the supine position and after 1-2 minutes of orthostatist in 1286 elderly persons (499 men and 787 women aged 70.447.54 years). The results showed that the prevalence of OH in elderly persons living in community was 18.5%. There are not any significant difference in OH between men and women. Prevalence of OH in “very old” group (75 years old or more) was higher than in 60 - 74 years old group (30.4% vs. 13.8%). The hypertensive persons had the prevalence of OH higher than that of the normotensive persons.

1305 older persons living in communities were included in an epidemiological survey to investigate the risk factor for atherosclerosis. The results showed that prevalence of risk factors in the elderly was high: dyslipidemia (47.5%), hypertension (45.6%), smoking (26.9%), obesity (18.3%) and diabetes/IFG (12.1%). The prevalence of hypertension in rural area was higher than in urban area. Prevalence of dyslipidemia, diabetes/IFG and obesity in urban were higher than in rural area. There are not difference in prevalence of hypertension, diabetes/IFG and obesity between men and women.

Hypertension of the elderly was studied. 1030 old subjects age 60 years old living in 3 communes (Phuong Mai – Ha Noi city, Phu Xuan - Hue city and Hoa Long – Ba Ria - Vung Tau Province). Average age: 70,44  7,54 years old. Blood pressure was measured and classified by JNC-VI standard. Results found a prevalence of general hypertension of 45,6%, simple high systolic pressure 24,8%. There is no difference in 3 localities and between male/female subjects, the prevalence increases in dependence with the age

84 patients with chronic venous insufficiency (30 males and 54 females, between 29-88 years old) were examined by color-Doppler. Reflux Venous Index was determined by pressing calf of legs when standing. Results: time, peak velocity of flow when releasing were higher than these when pressing. The mean Reflux Venous Index was 8.25. The more advantaged clinical stage, the higher Reflux Venous Index. This disease was more common at age >60 years old

Hypertension often causes cardiovascular complications, stroke, and has high rate of death, so physical examinations of hypertension could be interested in injury of target organ, coronary risk factors, specified causes, tests, and other diagnostic means. In the treatment, there are goals, lifestyle changes, using drugs, monitoring, treatment of hypertension bouts, and prevention

To effectively and safely treat diseases for the older, it needs to thorough understand the changes of pharmacokinetics such as absorption, distribution, metabolism, and excretion of drug; of pharmacodynamics and side-effects of drugs; of drug interactions, including interactions between drug and drug, or between drug and disease; to obey the principles of prescription for older by basic access, adjustment of dose... Incompliance of drug use is a big problem that often be forgotten in the treatment, and accounted for 50% of older patients. Impaired cognitive performance in older is one cause of incompliance

Dementia is a syndrome of failure of knowledge function, together with changing of behavior and loss of social function. Dementia is common in the elderly. The prevalence of this disease increase clearly by age. Dementia may appear suddenly, but gradually develop, chronically as in Alzheimer. The aim of treatment for patients with dementia is to enhance the quality of life and maintain maximum functional activities through improving the knowledge, the emotion and the attitude

In 6 communes, representative of 3 social economic zones of An Hai district of Hai Phong city, 1.597 old people were enrolled in this study. Among them, there was a rather high prevalence of chronical diseases. The most common diseases were: periodontosis 51%, blood lipid disorders in hypertensive patients 47.5%, cataract 42.4%, hypertension 40.8%, arthrose 38.8%, prostate tumor 26.3%, insomnia 19.5%, risk of obesis 10.8%, gastroduodenal ulcer 9.7%, constipation 8.4%, chronic bronchitis 8.4%. The prevalence was higher in > 80 -year - old age group than in the group aged 60-79 years old. In female subjects, the prevalences of cataract, arthrose, headache, insomnia, constipation were higher than in male, while in male, coronary arterical failure, lung tuberculosis, hemorrhoid, gastroduodenal ulcer,… were higher. In average, there were 3.8 diseases each elderly subject.

Clinical symptoms of venous thrombosis include swelling, redness, strain and edema in the leg. These symptoms are often nonspecific so the diagnosis of venous thrombosis must be confirmed by objective explores. Although the clinical symptoms can not confirm or exclude venous thrombosis, asking history carefully and examining signs and symptoms help diagnosis. Diagnosis of venous thrombosis can be done by venography, venous ultrasound, D-dimer quantitative. Venous thrombosis treatment aims to prevent thrombosis from spreading, recurrence, complications, pulmonary infarction, pulmonary hypertension and post thrombosis syndrome
