The prevalence and causes of anemia have been studied in 104 patients over 60 years of age admitted to a general medical ward in Jerusalem. In males and females, mean hemoglobin levels were about 1 g less than in the corresponding groups of healthy younger controls. A primary nutritional anemia could not be implicated in any of the 15 patients with hemoglobins below 11 g/dl. The most important causes of anemia were chronic renal failure, metastatic carcinoma, gastrointestinal bleeding, and infection. Conversely, in diseases with no adverse effect on erythropoiesis such as chronic ischemic heart disease, hypertension and diabetes, hemoglobin levels were equal to those of the younger controls. These findings indicate that although diminished serum iron and RBC folate levels may occasionally be found in elderly subjects, nutritional deficiency is seldom responsible for anemia in this age group in Israel- and anemia when present is often the manifestation of a chronic underlying disease.

A method is presented for the determination of serum lipid groups changes in conditions of venous fatty tolerance test as well as for time defining in reaching the initial levels of serum triglycerides. A variant of the quantitative thin-layer chromatography is applied, combined with carbonization and densitometry for lipid groups determination in the serum of 40 patients, subdivided into four groups: with chronic ischemic heart disease, with arterial hypertension, with obesity and a control ggroup. Lipid analysis was carried out by the 5th, 20th and 40th minute after the beginning of the test. After loading with Intralipid, it was established to develop quantitative changes not only in triglycerides but in the rest of the lipid groups as well. At the same time, the time for reaching the initial values of triglycerides, calculated by extrapolation, shows significant differences between the control group and those with ischemic heart disease and arterial hypertension. The investigation method adopted guarantees more thorough information about lipid changes after Intralipid infection, than the method with the determination of plasma opasity in corresponding time intervals. The criterion "time for reaching the initial values" characterized more fully the dynamic changes in triglycerides and could be used in the detection of latent anomalies in lipid metabolism.

50 patients with stenocardias in persisting arterial hypertension, of them 33 manifest coronary diseases, were orally treated with doses of propranolol up to 400 mg/die during a longer period. In the majority of the cases a good to very good therapeutic effectivity was to be proved in hypertension as well as in chronic ischaemic heart disease. The own favourable results of the treatment justify the estimation that proporanolol may be regarded as therapeutic remedy of choice in patients with simultaneous hypertension and chronic ischaemic heart disease. Moreover, a collective of 45 patients with different cardiovascular diagnoses under the new selective beta-receptor blocker Bonnecor (practolol) was observed. It is reported on first experiences in the sense of an intermediate information.

In 152 patients with diabetes mellitus, chronic ischaemic heart diseases and hypertension the so-called ptf-product resulting from the height of the amplitude of P and its time of spreading) measured in the lead V1 (PV1-index), was determined and compared with the values of 93 persons with healthy heart. Patients of the groups of diseases mentioned showed significantly higher pathological values than persons with healthy heart (limiting value -0.02 mms). A comparison between patients with chromic ischaemic heart disease at the age of 36-55 years and a group of diabetics of the same age without the clinical signs of an ischaemic heart disease resulted in no statistically ascertained differences. But compared with a group of persons with healthy heart of the same age the groups clearly differed: 63.9% of pathological values in the total group of disease compared with 18.5% of pathological values in persons with healthy heart. In 137 patients with latent diabetes (protodiabetes) in 54.7% also pathological ptf-values were found. It is possible that the determination of the ptf-product is able to ascertain already early forms of a chronic ischaemic heart disease still before its clinical manifestation. The large number of pathological values in patients with protodiabetes could be a first reference to early beginning disturbances of the left-sided atrial activity in the sense of a microangiopathy.

In this paper a survey is given on the group of risk in patients with diseases of the circulatory system under the stress of anaesthesia with special regard to arterial hypertension, chronic ischaemic heart disease, disturbances of cardiac rhythm and global heart insufficiency besides the generally acknowledged therapeutic principles for cardiological patients of risk. On the conditions of a surgical intervention the author adopts a definite attitude to the partly still contrary problems of the preoperative antihypertensive treatment and to the prophylactic therapy with glycosides. The most important diagnostic and therapeutic facts concerning the necessary interdisciplinary cooperation between internist, anaesthesist and operator in preparation and performance of an operative intervention in patients with circulatory diseases are described.

Thirty seven patients aged 70 and over (mean = 74 years) with an intracranial meningioma who had craniotomy between the years 1978-88 were reviewed. There were 20 women and 17 men. Resection was total in 28 (76%) and subtotal in 9 (24%) cases and each tumour was histologically verified. The location of the tumours were: base of skull 11, convexity 10, parasagittal 9, falx 6, and tentorial 1. The most frequent associated diseases were: hypertension (35%), chronic ischaemic heart disease (22%) chronic obstructive pulmonary disease (19%), and diabetes (14%). The Karnofsky Scale (KS) score before surgery ranged from 30 to 90 (mean = 59). It was less than 40 in ten patients. The length of anaesthesia during the surgical procedure varied from 4 to 12 hours and was not related to the outcome. There were two perioperative deaths (mortality = 5.4%). There were major complications in 8 patients and minor complications in 7 patients. In a mean follow up period of 29 months (shortest 6 and longest 96 months) the results were: excellent (KS 90-100) 39%, good (KS 70-80) 49%, fair (KS 60) 6%, and poor (KS 40-50) 6%. The difference between the mean preoperative KS value (KS = 59) and the mean postoperative KS value (KS = 80) was statistically significant (P less than 0.001). The results support a more aggressive therapeutic approach to the elderly patient with an intracranial meningioma.

The nutritional status of 93 noninstitutionalized elderly of the city of Perugia, mostly of them examined longitudinally, was assessed at the eleventh year follow-up. Diet is still rather rich and unbalanced. Alcohol intake in men is very high. Biological dietary errors have an impact on the nutritional status, particularly for folates, of the individual. But in this regard it is interesting to note that in some cases vitamin and mineral nutriture has improved at this follow-up. In addition the distribution of malnutrition is rather different from that of the previous follow-up. As on previous occasions, no correlation was observed between vitamin intake and corresponding nutritional status (with the exception of riboflavin). Obesity is rather common among women; men present a higher muscular area and hand muscular strength. The clinical evaluation of nutritional status evidences principally changes which are mostly ascribable to old age. Among the pathologies, chronic ischemic heart disease, hypertension, chronic respiratory diseases, osteoarthrosis and diabetes occur most frequently.

The effect of hypertension, hyperlipidemia, and the combination of both on acute and chronic myocardial ischemia were evaluated in a total of 30 male rabbits. After preliminary hypertension and/or hyperlipidemic load by loading of the abdominal aorta and/or cholesterol feeding, acute ischemia was produced by clipping of the left coronary artery. The banding produced elevation of carotid arterial pressure and left ventricular hypertrophy. Cholesterol feeding resulted in severe atheromatous changes in all sizes of coronary arteries. The intimal thickening was due to foam cell accumulation in all arteries examined. Animals pretreated with the combination of hypertension and hyperlipidemia displayed the most severe cardiolmegaly with advanced coronary atherosclerosis and chronic ischemic lesions of the myocardium, i.e., perivascular patchy fibrosis in the subendocardial area. Furthermore, electron microscopic detection of ultrastructural myocardial damage, involving glycogen depletion, sarcoplasmic edema, mitochondrial swelling, and contractile abnormalities, was also most frequent in this group. These changes were quantitated using the ischemic score. These results confirm the hypothesis that fatal ischemic injuries may occur clinically in human hearts with coronary insufficiency due to coexistence of hypertensive cardiomegaly and severe coronary atherosclerosis. They offer a model for further study of these combined effects.

Variations in arterial systolic (APs) and diastolic (APd) pressure, heart rate (HR) and electrocardiograms (ECG) were investigated in 22 normal men, 28 patients with arterial hypertension and 10 patients with chronic ischemic heart disease. Measurements were made during active orthostatic tests applied before and after submaximal exercises. In all three groups, APs diminished after exercise to a greater extent than before exercise. In hypertensive patients, APd increased significantly after exercise but changed insignificantly before exercise. In hypertensive patients with depressed T and ST, the level of ECG changes after exercise diminished by more than 50% as compared to the pre-exercise value.

76 patients after aortocoronary venous bypass operation, 34 patients with essential arterial hypertension at stage I or II (WHO) and chronic ischaemic heart disease, 96 patients with a chronic ischaemic heart disease of different degree of severity and 20 persons with healthy heart were examined concerning their behaviour of the R-amplitude in the exercise electrocardiogram. In all patients a standardized bicycle-ergometric exercise sitting and a coronarography as well as a ventriculography were performed. There is no statistically significant difference in the behaviour of the R-amplitude between patients with chronic ischaemic heart disease and persons with healthy heart. Indeed, hypertensives with chronic ischaemic heart disease significantly differ in their behaviour of the R-amplitude from persons with healthy heart, in the hypertensives with chronic ischaemic heart disease, however, the behaviour of the R-amplitude is indifferent, so that it is concluded that the criterion of the R-amplitude for the diagnosis of the chronic ischaemic heart disease in hypertensives cannot be used. An insufficient individual reproducibility supports this conclusion.
