Metabolic effects of long-term (at least 5 years) estrogen replacement therapy were studied. 301 patients were treated with replacement estrogen and 309 patients were untreated. Incidence figures for various metabolic diseases present at entry, and both during and after estrogen therapy were compared by statistical adjustments for certain group differences (Mantel-Haenszel statistics) and by statistical analysis. Long-term administration of estrogen to these women with hypoestrogenism was associated with significantly lower rates of development of cardiovascular disease (p .001), hypertension (p .001), osteoporosis (p .001), and fractures (p .01). The detrimental effects included a higher rate of abnormal uterine bleeding (47% of 207 women with uteri in situ) and an increase in the likelihood of developing adenocarcinoma of the endometrium. Cyclic adminsitration of estrogen did not seem to protect from the risk of endometrial carcinoma, however the addition of progesterone to sequential estrogen treatment did. It is believed that long-term estrogen therapy is of benefit for the woman deprived of estrogen function, particularly if this loss occurs at a relatively young age.

Severity of hypertension, frequency of secondary hypertension and prognosis have been compared in two groups of hypertensive men. The first group (n=686) was taken from a blood pressure screening of a total population sample. The other group (n=154) consisted of hypertensive men, referred to a hypertension clinic by physicians. The mean age of the groups was the same, (X=52 years, range 46--59 years). All went through the same investigations and were followed up and treated in a similar way at the hypertension clinic. The referred men had more severe hypertension, as shown by significantly more heart and kidney involvements. They also had a higher incidence of myocardial infarction, implying a poorer prognosis with regard to cardiovascular disease. The analysis shows the importance of a detailed description of studied groups, not only in terms of blood pressure, age and sex, but also with respect to the frequency and degree of present and previous signs of heart and kidney involvement. With such a description it is possible to compare results from different studies regarding pathophysiological mechanisms and the effect of treatment in hypertension.

Among the identified precursors of cardiovascular disease hypertension acts as a major risk factor. Hyperlipidaemia, hyperglycaemia and cigarette smoking are the other major factors that increase the risk of symptomatic cardiovascular disease (CVD). Other factors influence (obesity, stress, hyperuricaemia, etc.) but are not independent risk factors. More definitive information on the efficacy of multifactorial intervention is needed.

Eighteen patients with idiopathic optic neuropathy lacked symptoms and signs of cardiovascular and cerebrovascular disease, especially when compared to three groups of patients with sudden visual loss caused by retinal infarction, transient ischemia, and cerebral infarction. Many patients in the latter groups had hypertension, carotid bruits, heart disease, transient ischemic attack, and stroke. But among the patients with ischemic optic neuropathy, hypertension was the only evidence of cardiovascular disease, affecting 44% of the patients. We argue that, in many cases, ischemic optic neuropathy represents a direct and early complication of hypertension arterial disease affecting small arterioles supplying the anterior part of the optic nerve. The pathologic process may thus be similar or identical to lacunar infarction of the brain.

This study examined the effects of essential hypertension on measures of anxiety and depression for two age groups of hypertensive (free from hypertension-related pathology and/or cardiovascular disease) and normotensive subjects. Hypertensive subjects had significantly higher State Anxiety scores and Zung Depression scores than did normotensive subjects. These differences between the blood pressure groups were due largely to the scores of the younger hypertensive subjects. The results of the present study are consistent with previous results from our laboratory that have found that younger hypertensives differed (relative to controls) from middle aged hypertensives on measures, such as, symptoms reported on the Cornell Medical Index and WAIS Performance scores. The results of the present study were discussed within the context of age associated differences in response to hypertension and factors that might account for these differences.

Despite the recent publicity given to studies pointing out the negative side effects associated with the use of oral contraceptives, the pill is still the most common form of contraceptive used in Great Britain and constitutes the form of contraception for many women. Some of the negative effects currently receiving wide publicity, no longer represent a serious threat for the pill user; many of these effects have been negated or ameliorated by modifying the composition of the pills. In combined pills the estrogen content has been reduced from 150ug to 20-35ug. In the 2 major studies linking oral contraceptives with the development of cardiovascular disease most of the women in the studied population had taken pills containing 50-100ug of estrogen. Given the wide choice of pills currently available, many of the negative effects, such as nausea and pain, cna be ameliorated by choosing a more appropriate oral contraceptive for the specific patient. Other side effects such as headaches and poor cycle control can be treated by regimen modification. Although there is a relationship between pill use and hypertension, pills containing levonorgestrel in combination with 30ug of ethinyloestradiol have only a slight effect on blood pressure. Lactation is not reduced for women who take progestogen only pills. Fertility is successfully restored in almost all women shortly after they stop using the pill. Drug interaction failures can be avoided in many cases by prescribing pills containing 50ug of estrogen for women taking other drugs. In order to obtain immediate effectiveness, the combined pill can be started on the 1st day of the period instead of waiting until the 5th day.

The efficacy of correlating the L/S ratio in the amniotic fluid with fetal lung maturity has been substantiated in normal pregnancies. In gestations complicated by fetomaternal diseases, however, the assay is less reliable. This study involves 555 pregnancies in which there was a significant maternal, fetal, or placental disorder. The L/S ratio was related to fetal respiratory maturity as measured by Dubowitz criteria and the occurrence of RDS. The results show that pre-eclampsia, chronic hypertension, diabetes (Class D, E, F), significant cardiovascular disease, severe hemoglobinopathies, various congenital anomalies, chronic placental insufficiency, and prolonged ruptured membranes accelerated the L/S ration. Conversely, mild diabetes (Class B, C), intrinsic renal disease, hepatitis, collagen disease, hydrops fetalis, syphilis, and toxoplasmosis were associated with a delay in the L/S ratio. A significant increase in erroneous responses was noted in these patients when the L/S ratio was correlated to infant maturity and to the incidence of RDS. Possible mechanisms for these findings are discussed.

1500 men (aged 30-55 years) volunteered in a trial of early recognition of cardiovascular disease. History and clinical as well as biochemical data were obtained and compared with results of exercise ECGs. In the group as a whole abnormal ECGs were obtained in 6.2%, in a subgroup of those without exercise-dependent pain in the thorax, without hypertension and noraml resting ECG it was 3.8%, while in the presence of one or several of these risk factors it was as high as 17.8%. It is concluded that in any screening programme it is not reasonable to perform exercise ECGs in asymptomatic persons without risk factors, because in this group there is likely to be only a small percentage of abnormal findings and the number of false-positive ones is higher than that or correct positive ones. In connection with the known risk factors and risk indicators it would be best to define the risk group and, using selective indications, to go step-by-step from exercise ECG to additional invasive diagnostic measures such as coronary angiography.

Both the quality and the quantity of food ingested are relevant to the genesis of risk factors for coronary heart disease and the two are inseparable. Nevertheless they have a major common pathway through hypertension, which may well be the most important consequence of a high-protein, high-carbohydrate, high-fat, high-energy and high-sodium diet. Because body fatness is a strongly genetically determined characteristic and because it evolves over the whole period of childhood a vigorous and sustained programme of health education is required at all levels. The aim of such a programme is to effect a small shift in the fatness of the whole population; such a shift would dramatically and disproportionately reduce the incidence of obesity. Since the morbidity and mortality which is found in obese subjects arises primarily from cardiovascular disease in general, and coronary heart disease in particular, nutritional influences have obvious relevance to the prevention of coronary heart disease.

A relatively high incidence of heart failure is noted among patients with systemic lupus erythematosus (SLE) without clearly defined clinical causes. To evaluate left ventricular performance in patients with SLE without evidence of cardiovascular disease, noninvasive measurement of the systolic time intervals was carried out. Simultaneous recording of the electrocardiogram, phonocardiogram and carotid arterial pulsation were obtained in 25 patients with systemic lupus erythematosus and compared with 22 normal subjects. The patients with SLE had a shorter left ventricular ejection time (P less than 0.05), a longer pre-ejection period (P less than 0.02) and an increased ratio of pre-ejection period/left ventricular ejection time (P less than 0.005). These abnormalities on ventricular function were independent of age, duration of the disease, hypertension, renal involvement, anemia, immunologic activity and corticosteroid treatment. Several etiologic possibilities are discussed and the clinical usefulness of this method to detect and follow-up the cardiac dysfunction in systemic lupus erythematosus is emphasized.
