224 patients with coronary heart disease, hypertension, disturbances of cardiac rhythm or hyperkinetic heart syndrome were treated with the cardioselective beta-blocker Talinolol (Cordanum) for a period up to 3 years. In 239 examinations in intravenous or peroral application of this medicament we controlled among others the appearance of side effects. This test was carried out with the help of standardised questionings and clinical controls. Apart from registrations of ECG and blood pressure clinico-chemical investigations were included and in the long-term experiment also tests by dermatologists, otorhinolaryngologists and ophthalmologists. In the total number of patients the proportion of side appearances was 17,6%, in the long-term experiment (100 patients with on an average 12.9 months) 7%. The symptoms most frequently cited in the initial phase, such as fatigue, weakness, insomnia and nausea receded within 4 weeks apart from few exceptions. There did not appear any essential bradycardic disturbances of the cardiac rhythm, just as little were references to disadvantageous reactions in the sense of a practolol syndrome.

Hyperlipidemia has turned out to be the most important risk factor for coronary heart disease and necessitates frequently lipid lowering long-term treatment. Therefore, efficacy and tolerability of hypolipemic drugs are of great interest. The objective of the present study was to compare the safety, tolerability and effect on plasma lipids of Lovastatin and Bezafibrate retard in patients with hypercholesterolemia. 99 patients with total cholesterol of > or = 250 mg/dl after a 4 week standard lipid-lowering diet were treated another 4 weeks with placebo and then randomized to 400 mg Bezafibrate retard or 20 to 80 mg Lovastatin given once a day for 12 weeks. Mean changes from baseline in total cholesterol, LDL cholesterol and triglycerides were significantly reduced, in HDL cholesterol increased in both treatment-groups (p < or = 0.01). The effects of Lovastatin on total cholesterol and LDL cholesterol were more pronounced than those of Bezafibrate retard (p < or = 0.01), while Bezafibrate had a larger effect on triglycerides (p < or = 0.05). The frequency of clinical adverse experiences was low and similar among treatment groups, the frequency of laboratory adverse experiences was higher in the Lovastatin group. One patient in the Bezafibrate group was withdrawn because of nausea, one patient in the Lovastatin group because of GGT elevation.

The methods used presently for abortion of the attacks of migraine and cluster headache are not fully satisfactory which causes that the search for new therapies is continuing. Although the mechanism of migraine attacks remains unexplained, it is thought that an important role in it is played by serotonin receptors, vasodilation in certain regions and opening of arteriovenous communications in the head. Sumatriptan is an agonist of 5-HT1 -like receptors and exerts a selective vasoconstricting effect on the arteries of the head, particularly in the rami of the carotid artery. In 1988 the first reports appeared on the effectiveness of the drug in migraine attacks. In the following years extensive, multicentre and international studies of the drug were carried out on over 600 healthy volunteers and nearly 6000 patients with migraine. The studies demonstrated that Sumatriptan was effective in abortion of migraine attacks. After oral administration of 100 mg or subcutaneous injection of 6 mg in nearly 70% of cases the attack regressed or was greatly alleviated, similarly as other symptoms accompanying the headache such as photophobia, nausea, vomiting. Studies were undertaken also on the effectiveness of Sumatriptan in emergency treatment of cluster headache, and good results were again achieved. The tolerance of the drug is good, although in some cases side effects develop, usually transient and mild, among them tingling, feeling of pressure, heat or heaviness of the head or chest, taste change and burning sensation at the site of injection. Sumatriptan, similarly as all novel drugs, requires caution in its use, particularly in patients with coronary heart disease and hypertension, and also in old patients. As yet, the use of the drug in paediatric migraine or in pregnancy is not recommended.

Fourteen patients with metastatic breast cancer previously treated with one chemotherapy regimen received Pirarubicin at a dose of 70 mg/m2 at 3-week intervals. In 7 patients the dose had to be reduced, in 1 patient to 40 mg/m2 and in 6 patients to 50-60 mg/m2. There were 1 complete and 2 partial remissions. These objective responses were observed in soft tissue, lung and pleural areas and lasted 1+; 4+ and 5+ months. Grade 3 and 4 leukopenia was found in 42%, grade 3 thrombocytopenia in 2%, grade 3 nausea/vomiting in 29% of the cycles. Grade 1 and 2 alopecia occurred in 64% of the patients, the remaining 36% of the patients did not suffer from any alopecia. No cardiotoxic side effects were observed in 13 patients. In 1 patient with severe coronary heart disease extrasystoles and reduction in left ventricular ejection fraction occurred. Pirarubicin has antitumor activity in previously treated metastatic breast cancer patients.

Between 1984 and 1987 there were 7 cases of sudden cardiac death during organized mass runs in Switzerland, and between 1978 and 1987 there were 3 cases during the nine largest mass running events (total 8 cases of sudden death during the race). Based on numbers of participants in all events 1984-1987, or in the nine largest events 1978-1987, an incidence of 1 sudden death per 129,500 hrs. of running (95% confidence interval 1/62,500-1/263,000 hrs.), or 1 sudden death per 117,000 hrs. of running (1/45,000-1/311,000 hrs.) respectively, was estimated. This estimate is higher than the rate of 1 sudden death per 396,000 hrs. of noncompetitive jogging found in a study from the United States (Thompson et al.: J. Amer. med. Ass. 1982; 247: 2535-2538). The Swiss incidence of sudden cardiac death during organized mass runs was 50 to 1000 times higher than the incidence expected by chance alone (as estimated from national death register data). All 8 cases of the study were men, the younger four aged 23 yrs. on average (range 20-31 yrs.), the older four aged 49 yrs. (46-53 yrs.). Autopsy in three of the younger men identified hypertrophic cardiomyopathy in one instance whereas in the two other cases no plausible cause of death could be found. The two autopsies performed in older men both showed severe coronary heart disease. Only in 1 case out of the 8 were possible prodromal symptoms of the subsequent death, such as fatigue and nausea, observed, and the average prevalence of known cardiovascular risk factors was low. None of the 8 runners dying suddenly was completely untrained, but 6 out of 8 had only modest running experience, i.e. a low number of years of running. This study confirms that there is probably a clearly increased risk of sudden death during running events with a competitive character, but this acute elevation of risk should probably not be overstated in view of both its very low population - attributable risk and the important potential of regular exercise for overall coronary risk reduction and health promotion.

The mechanisms and cardiovascular effects of omega-3 fatty acids are reviewed. Omega-3 polyunsaturated fatty acids are the major ingredient found in commercially available fish oil products. The incidence of many diseases, including coronary heart disease, diabetes mellitus, and psoriasis, is lower in Eskimos, who ingest diets rich in omega-3 fatty acids, compared with European controls. Potential mechanisms by which these fatty acids cause their many physiologic effects include competing with omega-6 fatty acids for prostaglandin and leukotriene pathways and enhancing cell membrane fluidity by virtue of the high degree of unsaturation. Numerous studies have documented longer bleeding times and decreased platelet aggregation in subjects ingesting omega-3 fatty acids. Omega-3 fatty acids may reduce serum cholesterol concentrations by decreasing the synthesis of very low density lipoprotein and, therefore, low-density lipoprotein. Blood viscosity is significantly and uniformly lower in subjects receiving omega-3 fatty acids compared with controls. Potential risks of supplementation with fish oils include hypervitaminosis A and D, vitamin E deficiency, increased bleeding times, decreased platelets, and ingestion of contaminated fish. Supplementation with moderate amounts of omega-3 fatty acids appears to be relatively safe. Possible adverse effects include nausea, diarrhea, and a "fishy" taste. Properly controlled, long-term clinical trials are needed to determine whether supplementation with omega-3 fatty acids would be therapeutically beneficial in various patient populations and disease states.

The analgetic effect and the side effects of buprenorphine (Temgesic) and morphine were compared in a double blind randomised study in 76 patients with suspected acute coronary heart disease. In 68 patients the acute coronary heart disease could be proven, in 61 patients the protocols could be entirely analysed. In 7 of 30 patients on buprenorphine and in 10 of 31 on morphine the analgetic effect was not sufficient (n.s.). The observed side effects were hypotension, bradycardia, nausea, vomiting, vertigo, reduction in respiratory rate and sedation. There were no significant differences in the rate of these side effects in the two groups. The average reduction in respiratory rate was more prominent in the buprenorphine group (-8 vs. -3/min. p less than 0.001) but we found no significant difference in both groups in the number of patient with a respiratory rate less than 12/min. We conclude that buprenorphine is safe for use in the pain therapy of patients with acute coronary heart disease and has a similar analgetic effect and profile of side effects as morphine. It can be used as an alternative to morphine in acute coronary heart disease.

The role of pindolol in treating ventricular arrhythmia was studied in 43 patients with this disorder. Of these patients, 23 had coronary heart disease, 5 had valvular disease, and 15 had no demonstrable heart disease. patients underwent acute drug testing with 20 mg pindolol (phase 1) followed by maintenance therapy (phase 2) for 3 days (20 to 80 mg daily). Efficacy during both phases was evaluated by ambulatory monitoring and treadmill exercise testing. During acute drug testing, 50% of te patients responded. A concordant response between acute drug testing and phase 2 monitoring was seen in 81% (p less than 0.005) of patients and between acute drug testing and phase 2 exercise testing in 88% (p less than 0.005). Arrhythmia was suppressed during the phase 2 exercise test in 53% of patients; these included 80% of the patients without heart disease and 50% of those with coronary heart disease (not significant). During phase 2 monitoring, 60% of patients without heart disease responded vs. 25% with coronary heart disease (not significant). Side effects occurred in 12 patients (28%). These included congestive heart failure (3 patients); fatigue, lightheadedness, and insomnia (2 patients each); nausea, tremor, urinary retention, and bronchospasm (1 patient each); and aggravation of arrhythmia (7 patients). It is concluded that although pindolol alone is marginally effective for treating ventricular arrhythmia in patients with coronary heart disease, it appears to be more valuable in those without heart disease, especially when arrhythmia is provided by exercise. Acute drug testing proved highly predictive of the results with maintenance therapy and is a valuable rapid-screening procedure for identifying potential responders to pindolol.

The use of dobutamine stress echocardiography for the evaluation of coronary artery disease is rapidly expanding. Despite its widespread use, the feasibility and safety of dobutamine stress echocardiography has not been sufficiently documented. Between November 1992 and June 1995, we performed 1000 dobutamine stress echocardiographies. There were 744 men and 256 women with a mean age of 59 +/- 11 years. Anti anginal medication was not routinely withdrawn before the test. The mean maximal dobutamine dose was 41,4 +/- 10 mu g/kg center dot min(-1). Atropine was given additionally in 440 patients, with a mean dose of 0.5 mg. In patients receiving beta-blockers additional atropine was more often necessary as compared to those not receiving beta-blockers (278/457 = 61% versus 162/543 = 30 %, p < 0.0001). Reasons for discontinuing dobutamine infusion were achievement of target heart rate (64 % of cases) and maximal dose (12 % of cases). In 791 (79,1 %) patients no side-effects of dobutamine stress echocardiography were noticed. Termination of the study because of adverse side-effects occurred in 6.6 %. A total of 103 (10,3 %) noncardiac side-effects were observed: dizziness or nausea 6.4 %, headache 1.7 %. In one patient a focal cerebral seizure occurred. 156 cardiac side-effects occurred: blood pressure decrease of more than 20 mm Hg in 25 patients, extreme palpitations in 16 patients and pulmonary edema in one case. Most common cardiac side-effects consisted of arrhythmias (11.4 %): 9.1 % ventricular and 2.3 % supraventricular arrhythmias. Most ventricular arrhythmias were less severe (uniform and multiform premature ventricular beats, ventricular bigeminy or couplets in 71 patients). Nonsustained ventricular tachycardia, with a maximum duration of 20 s, occurred in 18 patients. In one patient sustained ventricular tachycardia developed and progressed towards ventricular fibrillation. This patient could be successfully defibrillated. Supraventricular arrhythmias presented as new atrial fibrillation in 10 patients, supraventricular tachycardia in three patients, junctional rhythm with a short decline in heart rate in nine patients and a second-degree AV block in another case. Dobutamine stress echocardiography has proven to be a safe and feasible method in the diagnosis of coronary heart disease. Minor side-effects are common and sometimes unpleasant for the patient, but do not often require termination of the study. Severe side-effects are seldom (< 1 %), but nevertheless, adequate medical and technical (defibrillator) support should be rapidly available.

Toremifene is a chlorinated tamoxifen analogue that is indicated for the treatment of postmenopausal hormone-dependent breast cancer. It competes with estradiol for estrogen receptors and has growth-inhibitory effects on MCF-7 breast cancer cells. At concentrations < 10(-6) mol/L, this growth inhibition can be reversed by estradiol, but at higher concentrations toremifene is cytotoxic. In dimethylbenzanthracene (DMBA)-induced mammary cancer in rats, toremifene has been shown to decrease the number of new tumours and to inhibit the growth of existing tumours. Toremifene causes growth inhibition by suppressing mitosis and inducing apoptosis. The mechanism by which these events occur may involve the induction of transforming growth factor-beta 1 and inhibition of insulin-like growth factor-1 (mecasermin). Toremifene is primarily an antiestrogen, but it has some estrogen agonist properties in postmenopausal women. The latter are reflected by the fall in luteinising hormone and follicle-stimulating hormone levels and the rise in sex hormone-binding globulin levels that are associated with its use in most women. After estrogen priming, toremifene 68mg administered orally has been found to exert a similar antiestrogenic effect on the vaginal epithelium in postmenopausal women as tamoxifen 60mg. The half-life of toremifene in plasma is 5 days, and the drug is > 99% bound to plasma proteins. The main metabolites of toremifene are N-demethyl-toremifene and deaminohydroxy-toremifene. Altered liver, but not kidney, function affects the pharmacokinetics of toremifene. Toremifene 60mg daily is as effective as tamoxifen 20mg daily in the treatment of postmenopausal hormone-dependent breast cancer, producing a response in about 50% of patients. Soft tissue and visceral metastases respond better to toremifene than bone metastases. Most of the adverse effects of toremifene are related to its activity at estrogen receptors and include hot flashes, vaginal discharge and nausea. Although toremifene decreases antithrombin III levels slightly, the incidence of thromboembolic complications is low. Thus far, no carcinogenic effects have been noted in humans, and preclinical data are mostly reassuring. Toremifene has favourable effects on serum lipids, and thus has potential in preventing coronary heart disease. Although toremifene is somewhat more expensive to use than tamoxifen, toremifene is an effective and well tolerated alternative to tamoxifen in the treatment of postmenopausal women with hormone-dependent breast cancer. No formal pharmacoeconomic comparisons of toremifene and tamoxifen have yet been published. Toremifene is potentially safer than tamoxifen in relation to carcinogenic effects and effects on serum lipids.
