The effects of a new beta-blocking agent (CI 778) were studied in 8 patients in whom non-invasive data suggested absence of significant organic
heart disease
. The left ventricular hemodynamics at rest and during bicycle exercise were measured before and after intravenous administration of 0,9 mg/kg body weight. With exercise there was a significantly smaller increment of heart rate (18%) after beta-blockade.
Stroke
volume index at rest was significantly lower (17%) after administration of CI 775; the difference disappeared with exercise. There was an 18% decrease of the resting cardiac output after CI 775 and a 23% decrease with exercise. Significant changes at rest and with exercise indicating a negative inotropic action of CI 775 were noted for max dP/dt and peak measured velocity of circumferential fiber shortening (Vpm). The left ventricular enddiastolic pressure with exercise increased with borderline significance by 41% after CI 775. Also left ventricular
stroke
work index at rest and with exercise decreased moderately (n.s.), the systemic arterial resistance changed to the same extent as cardiac output decreased. Also the arterial venous oxygen difference increased after CI 775 only according to the decrease of cardiac output. The data suggest the hemodynamic properties of CI 775 are located between propranolol and practolol within the spectrum of available beta-blockers.

The concensus conclusions reached at a concensus development conference on Estrogen Use and Postmenopausal Women in September 1979 are based on 3 position papers prepared for the conference, the response of the panel, and the general discussion by the audience, followed by the panel and other conference participants. The evidence for the efficacy of estrogens in treating specific conditions associated with menopause was reviewed 1st. It was accepted that estrogens are more effective than placebo in decreasing the frequency and severity of vasomotor symptoms. Estrogens are effective in overcoming the atrophy of the vaginal epithelium and the associated symptoms. Present evidence does not justify the use of estrogens to treat primary psychological problems. The validity of 3 randomized trials indicating that exogenous estrogens can retard bone loss if given around the time of menopause was acknowledged. There is no convincing evidence that estrogens in customary doses increase the risk of thromboembolic phenomena,
stroke
, or
heart disease
in women who have undergone natural menopause. Evidence was also reviewed concerning adverse effects associated with post-menopausal estrogen use. In the absence of exogenous estrogens, the incidence of endometrial cancer is about 1/1000 postmenopausal women per year. This rate increases severalfold beginning after about 2-4 years of use of 0.625 or 1.25 mg of conjugated estrogens daily. Cystic hyperplasia of the endometrium, regarded as a premalignant condition, has been associated with unopposed estrogen, whether endogenous or exogenous.

The present paper reports the third part of an investigation of first-time cerebrovascular strokes occurring in people under the age of 70. The long-term prognosis for 214 patients discharged alive from hospital after the acute phase of the
stroke
is presented. The clinical and laboratory findings for 114 patients alive at the time of a follow-up examination 32 months after the
stroke
are discussed. The long-term prognosis could be predicted best by a score, calculated from the neurological findings on admission after the acute
stroke
. Recurrence of
stroke
was associated with a very high mortality. Forty-five per cent of the patients who survived the first month had died by the time of follow-up. About 15% were able to return to normal life or go back to work. There was a trend among patients originally severely handicapped to improve their performance ability. Factors influencing the chances for rehabilitation are discussed. Among the survivors there was a strikingly high percentage of patients with overt diabetes or decreased glucose tolerance, of patients with arteriosclerotic
heart disease
and patients with elevated serum triglyceride levels. These findings are discussed.

A person's sexual readjustment following a physical disability has traditionally been ignored by health care professionals. Since the occupational therapist often facilitates a person's resumption of activities of daily living, the therapist is in a special position to provide counseling. Understanding, support, and correct information are needed most. As derived from a search of the literature, sexual functioning is discussed in relation to the following disabilities:
stroke
,
heart disease
, diabetes mellitus, muscular dystrophy, multiple sclerosis, renal disease, spinal cord injury, pulmonary disease, arthritis, and alcoholism.

The chemical composition of ultracentrifugal fractions of VLDL (d less than 1006), LDL (d 1006-1063) and HDL (d less than 1063) has been studied in males affected by atherosclerosis of different vascular beds. Thirty-seven subjects affected by post-infarction
cardiopathy
(M.I.) showed significantly higher values of total-C, VLDL-C and LDL-C when compared to 52 controls. Twenty-three patients affected by non-occlusive ischaemic heart disease (I.H.D.) showed higher values than controls of total-C, VLCL-C, LDL-C, total TG, VLDL-TG, and GDL-TG. Twenty-three patients with atherosclerosis of the inferior limbs (P.A.) were characterized by increased levels of total-TG, VLDL-TG, VLDL-C, HDL-C. A group of patients who had suffered a
stroke
from cerebro-vascular disease (C.V.D.) did not show any significant difference from controls. In the M.I. group, 56% of the patients had a high level of C-VLDL. Patients with I.H.D. were characterized mostly by an increase in C-LDL, Patients with P.A. showed the highest values of total -TG, VLDL-TG and LDL-TG. Some of the observed differences are probably due to different metabolic backgrounds. Some other differences may be due to variations in dietary habits after heart infarction. Patients with levels of plasma cholesterol and triglyceride beyond the 90th percentile of the normal group showed many abnormalities in the chemical composition of their lipoproteins. It is noteworthy that increased amounts of cholesterol may collect in lipoprotein classes different from LDL while increased amounts of triglyceride may collect in classes different from VLDL.

The treatment of operable breast cancer in eighty-two patients older than seventy years was analyzed. The cancers were treated at an advanced stage and the axilla was involved as frequently as in younger women. The factors influencing survival differ because of competing mortalities from
heart disease
and
stroke
. The risks are discussed in relation to life expectancy and treatment method.

Arteriosclerotic heart disease is a major cause of death in insulin-requiring juvenile diabetic patients treated for end-stage renal disease. Eleven consecutive diabetic patients without clinical evidence of coronary artery disease underwent complete cardiac evaluations, including coronary arteriography, as part of transplant recipient work-ups. Seven were women and four were men; their mean age was 32 (21 to 50 years). Angiographically, every patient had multifocal atherosclerotic coronary disease. Four of seven patients tested had positive-stress electrocardiograms. In this group of patients followed for a mean of 19.8 months, eight died. Of these deaths, six were due to coronary heart disease and another due to a
stroke
. In two patients who became clinically symptomatic, serial angiograms revealed progressive disease of the coronary circulation; in one case, despite normal renal allograft function and serum lipid levels. The mode of end-stage renal disease treatment, serum lipids or blood pressure control could not be linked to mortality. It is concluded that arteriosclerotic
heart disease
is common in diabetic patients with end-stage renal disease even when angina is absent. The natural history in this high risk population is an important consideration in the selection of patients for end-stage renal disease treatment.

In 31 patients with congenital or acquired
heart disease
, functional class III NYHAC, effects of Sulfentanil (R 30730)--a new analgetic--on hemodynamics, inotropic state and myocardial oxygen consumption have been investigated intraoperatively, during extracorporeal circulation and postoperatively. Results are compared to a fentanyl-group and control-group. There was almost no change in cardiac index and
stroke
index. In comparison to fentanyl (dose relation fentanyl: sulfentanil = 10:1) there was a more pronounced decrease in aterial pressure, left ventricular pressure, peak dp/dt and myocardial oxygen consumption (-20%) in the sulfentanil-group. In contrast to the fentanyl-group there was, however, no increase in total pulmonary resistance with sulfentanil.

In 24 patients with congenital or acquired
heart disease
, functional class II--IV New York Heart Association Classification, effects of aminophylline on hemodynamics have been investigated intraoperatively, during extracorporeal circulation and postoperatively. Aminophylline caused a decrease in arterial pressure, left ventricular pressure, right and left atrial pressure, total systemic resistance and total pulmonary resistance. At the same time there was an increase in heart peak, peak dp/dt, cardiac index and
stroke
index. Our results demonstrate beneficial cardiac and extracardiac effects of aminophylline in man.

The field of cardiac blood pool imaging has been reviewed. The radioisotopes and radiopharmaceuticals used for this purpose have been discussed. Data related to the radiation exposure from these agents were presented and compared with the radiation exposure of a conventional contrast angiogram. Application of cardiac blood pool imaging to the qualitative evaluation of pericardial effusions, cogenital
heart disease
, acquired
heart disease
, and cardiac shunts have been discussed. Quantitative methods for measuring cardiac output,
stroke
volume, left ventricle ejection fraction, left ventricle end-diastolic volume, percent mitral valve regurgitation, and Qp:Qs flow ratios in both right-to-left and left-to-right shunts were presented in detail. Where possible, correlation with contrast angiographic findings was given. Newly developed techniques of ECG gating of cardiac images were also described in detail. This description has included applications of these techniques for evaluation of regions of myocardial dyskinesis and to quantitation of left ventricle diastolic volume, ejection fraction, time between ejection onset and peak systolic flow, ejection duration, and peak circumferential fiber shortening. Once again, these were correlated with contrast angiography where possible. It is concluded that cardiac blood pool imaging is a useful procedure capable of yielding good qualitative and quantitative results in a wide variety of clinical cardiac diseases and that these results compare favorably with those obtained by contrast angiography. Although there are limitations in the present techniques, solutions to at least some of these limitations are possible. Because of its simplicity, safety, and low cost relative to cardiac catheterization, more widespread use of these procedures is urged.
