[Blood morphology in elderly persons over 90 years old].

In order to assess blood cell count in a late senescence we examined 56 persons (44 women and 12 men) in age 90-99, in a good condition. Over 70% of obtained results were in normal range. The most frequent abnormalities were: anemia (28.6%), leukopenia < 4,000 in 1 mm3 16.1%, thrombocytopenia < 125,000 in 1 mm3 -10.7% of subjects. In a white blood count low value of rod neutrophils and monocytes were found. The results show that the haematological diagnosis in elderly does not require any special references intervals.

[Serum lipids in persons over 90 years of age].

UNLABELLED: Because of different views on the significance of the serum lipids as a risk factor of atherosclerosis in the elderly we evaluated the levels of total cholesterol (CH), HDL-cholesterol (HDL-CH) and triglyceride (TG) in the group of 56 very old (over the 90), who were in a good health condition. Desirable values of lipids were found respectively: CH in 55.4% of subjects, HDL-CH in 85.7% and TG in 89.3%. In the elderly with hypercholesterolemia (CH > 250 mg/dl) we simultaneously found high level of HDL-CH (x = 69.3 mg/dl). CONCLUSIONS: The serum lipids levels in the elderly over 90 were generally within the limit of desirable values. On the other hand subjects who had higher level of cholesterol had also high level of HDL-CH (69.3 mg/dl). Considering our results we came to the conclusion that high level of HDL-CH is one of the favoring factors to reach an advanced age.

[Prevalence of autoantibodies in serum of healthy persons over 85 years of age].

Aging is believed to be associated with the increase in the frequency of autoantibodies. However, as the recent studies suggest the immunological defects are not the consequence of the aging process but they could be a result of underlying diseases. We investigated the prevalence of the anti-nuclear (ANA), anti-mitochondrial (AMA), anti-smooth muscle (SMA), antibodies to gastric parietal cells (PCA) and thyroid anti-microsomal autoantibodies (anti-Tg) in the sera of the selected healthy elderly over 85 years of age. We discovered ANA in 10% of subjects, AMA-5% and PCA in 15% in the group that we examined. Anti-smooth muscle and thyroid anti-microsomal antibodies have not been observed. Autoantibodies were less frequent than in other studies, but our results have shown slight increase of some autoantibodies in the healthy elderly.

[Rhythm and conduction disorders among the adult population. Epidemiologic data].

2.487 resting ECG were examined which is 61.3% of randomly chosen group of inhabitants of Cracow, aged from 20 to 93. There were: sinus tachycardia (HR 100)--4.2%, extrasystole--2.7%, fibrillatio atriorum 1.4%, blocks A-VI0--0.9%, intraventricular conduction defects--3.6% (most often LAH). Prevalence of disturbances of rhythm and conduction increases with age, mainly after 60.

[Response of the cardiovascular system in elderly patients to intravenous infusion of isoproterenol and adrenaline].

The effect of gradually increasing doses of catecholamines on the heart rate, arterial pressure and the left heart ventricle systolic time intervals has been studied in the group of 30 aged subjects (70 to 95 years old) and the control group aged 23 to 30 years. The initial resting QS2I, LVETI, PEPI, heart rate and diastolic pressure were similar in both groups studied whereas the chronotropic and inotropic response as well as the vasodilatation were weaker in the aged. The disturbed mechanisms of adaptation in the aged could be caused by limited response of the circulatory system to adrenalin secreted during the stress states.

[Electrocardiography in elderly inhabitants of Krakow. Epidemiological study].

The electrocardiographic records were performed in the randomly chosen area of Cracow. The results were obtained from 512 persons (153 M and 359 F) aged 70-93 years. Normal electrocardiograms observed in 25.4% of the studied population. The prevalence of electrocardiographic abnormalities was as follows: ST segment depression--40.0%, patterns of infarction--17.2% and left ventricular hypertrophy--10.4%. On the contrary right axis deviation, bradycardia, sinus arrest, II and III of a-v blocks were rarely observed. The prevalence of electrocardiographic abnormalities in the aged in Cracow is in the accordance with the findings observed in the countries with high risk of cardiovascular diseases.

[Polycardiographic evaluation of left ventricular function in the elderly].

Polycardiographic recordings have been carried out in 57 individuals (16 men and 41 women), aged between 70 and 97 years (mean age 78.3 years), both at rest and during the stimulation of circulatory system by the cooling of hand. Systolic time intervals of the left ventricle and QT/QS2 ratio have been evaluated. It was found, that systolic time intervals at rest did not differ significantly from those given by Weissler. Cooling of hand has been manifested by: prolongation of LVETI, decrease in PEP/LVET, prolongation of QS2I, and decrease in QT/QS2. Results suggest indirectly that myocardium of the elderly adapts to the stimulation through Frank-Sterling mechanism.

[The state of the circulatory system in the elderly].

Fifty six persons (15 men and 41 women) aged between 90 and 99 years were examined to assess their health determining longevity. Circulatory system was evaluated with the aid of anamnesis, physical examination, chest X-ray and ECG. Clinical symptoms of the circulatory disease were diagnosed in 55.4% of tested persons, including: ischaemic heart disease in 42.9%, arterial hypertension in 35.7%, and circulatory failure in 23.2%. Normal ECG records were noted in 10.7% of the tested elderly persons. The most frequent electrographic abnormalities included: decrease in ST, LAH and atrio-ventricular block of the I degree. Incidence of ECG abnormalities did not depend upon the clinical state. An advanced age (over 90 years) is achieved also by the persons with marked circulatory disorders.
