A multidimensional relationship exists between cardiovascular disease and affective disorder that includes the observations that (1) there is a high rate of depression in the postmyocardial infarction period, (2) the presence of depressive illness adversely affects the prognosis of cardiac disease, and (3) depressed patients have a higher-than-expected rate of sudden cardiovascular death. The authors discuss these topics and the clinical management of depression in patients with significant preexisting heart disease. The cardiovascular effects of the tricyclic antidepressants and recently introduced nontricyclic antidepressants are reviewed with a focus on how the clinician can safely and effectively treat affective disorder in patients with severe cardiac disease.

Multi-infarct dementia (MID) and dementia of the Alzheimer type (DAT) are the main syndromes in the elderly. This study aims at evaluating the possible differentiation of these syndromes on a clinical basis. The patient population consisted of demented patients hospitalized during the period April 1, 1988-September 30, 1990 at the Department of Cerebrovascular Diseases. The study included 40 patients with MID and 25 with DAT. The clinical diagnosis of dementia included medical history, neurological examination, psychiatric interview and laboratory diagnostic investigations. The severity of the dementia symptoms was rated by many rating scales and a battery of neuropsychological tests. This model of clinical procedure permitted for differential diagnosis between vascular and degenerative dementia, according to DSM-III-R criteria. Patients with multi-infarct dementia of the Alzheimer type did not differ significantly with regard to age, mean duration of cognitive impairment and level of education. In the DAT group women outnumbered men, and this was statistically significant. It should be emphasized, that a great majority of patients with cerebrovascular lesions developed early cognitive impairment, that means within the first year after stroke. In the MID group hypertension, heart disease and smoking were statistically more frequent than in the DAT group. For the preliminary evaluation the severity of cognitive impairment was quantified by Mini-Mental State and Dementia Scale. These scales showed that the degree of dementia was significantly greater in DAT patients as compared to MID patients, whereas the severity of depression assessed by Hamilton's Scale was mild and similar in both group.(ABSTRACT TRUNCATED AT 250 WORDS)

Moderate drinking for the elderly of both genders is no more than one drink per day, where a drink is defined as 12 oz of beer, 5 oz of wine, or 1.5 oz of spirits. Age does not affect the rate of absorption or elimination of alcohol. Lean body mass decreases and adipose tissue increases with age, however, resulting in a corresponding decrease in the volume of total body water. With a smaller volume of distribution, an alcohol dose identical to that administered to a younger individual of the same size and gender will produce a higher blood alcohol concentration in the elderly. Low-dose alcohol stimulates appetite and promoters regular bowel function. In the well-nourished nonalcoholic elderly, the negative impact of alcohol consumption on nutrition is minimal. Alcohol consumption improves mood by increasing feelings of happiness and freedom from care while lessening inhibitions, stress, tension, and depression. Although in the laboratory low-dose alcohol improves certain types of cognitive function in young men, in other types of task performance, alcohol induces impairment, which worsens with age. The effects of alcohol on sleep are primarily detrimental, worsening both insomnia and breathing disturbances during sleep. Although the role of alcohol consumption in mortality from heart disease has not been investigated in the elderly, moderate drinking appears safe. Under some circumstances low-dose alcohol may produce analgesia whereas in others it may worsen pain. The elderly use a significant proportion of both prescription and over-the-counter medication, a large variety of which interact with alcohol. Alcoholic beverage consumption may exacerbate cognitive impairment and dementias of other etiology. Although some studies suggest that moderate use of alcohol by institutionalized senior citizens appears to produce benefits including improved socialization, separation of the effects of the social situation from those specifically attributable to alcohol remains to be accomplished. Older individuals who want to drink, have no medical contraindications, and take no drugs (prescription or over-the-counter) that interact with alcohol, may consider one drink a day to be a prudent level of alcohol consumption. Patients should be counseled to avoid alcohol consumption immediately prior to going to bed in order to avoid sleep disturbances. They also should be cautioned against potential drug-alcohol interactions and told to avoid alcohol ingestion prior to activities such as driving. The decision to recommend a particular level of alcohol consumption in any given patient must, however, be carefully tailored not only to that individual's specific medical needs but to his or her social and environmental circumstances as well.

We report the use of adrenaline in a 62-year-old woman with carcinoid heart disease who underwent double valve replacement. She was given an intravenous infusion of octreotide throughout the peri-operative period. Following the termination of cardiopulmonary bypass she developed profound hypotension which proved to be refractory to various therapies but responded to adrenaline. Adrenaline is said to be contraindicated in carcinoid syndrome, but we would suggest the consideration of its use in such cases where the hypotension may result from myocardial depression rather than from a carcinoid crisis.

This study examined age differences in the quality of self-report data in patients with chronic disease conditions (hypertension, diabetes, heart disease, depression). Data are from 2,304 patients in three health care systems in Los Angeles, Chicago, and Boston. Results support the idea that self-report health data can be gathered from older and younger patients without significant decrements in data quality. Specifically, results showed: (1) small decreases in the reliability of multi-item measures with age, primarily occurring in balanced scales; (2) little evidence of differences among age groups in response set or the tendency to respond "don't know" or "uncertain," although older patients had a greater tendency to respond in a socially desirable manner; (3) higher item nonresponse in older patients; (4) little variation in item nonresponse by type of question or question placement; (5) generally high panel retention in all age groups, supporting the value of repeated follow-up; and (6) similar known-groups validity across age groups.

Myocardial perfusion scintigraphy with thallium-201 was performed in 33 subjects (mean age 45 years, range 28-61) with exercise-induced, rate-dependent left bundle branch block (LBBB) in order to assess both the value of Thallium-201 myocardial imaging for the diagnosis of coronary artery disease (CAD) and the pathogenesis (ischaemic or not) of the conduction defect. Of the 33 patients evaluated, 16 had chest pain suggestive of CAD and 17 were asymptomatic. None had a history of prior myocardial infarction or clinical and echocardiographic signs of heart disease. LBBB appeared at a heart rate ranging from 70 to 160 b.min-1. Eighteen patients showed repolarization abnormalities (ST segment depression with deep inverted T waves) compatible with ischaemia, after QRS normalization. Thallium-201 myocardial uptake was normal in 12 subjects; in the remaining 21, reversible Thallium-201 defects were demonstrated in the septum (18 patients), septum and apex (2), and septum and infero-apical wall (1). No patient had irreversible defects and all had normal coronary angiography, with negative ergonovine tests for coronary artery spasm. The patients were followed up for a mean of 43 months (range 16-80). One patient died from sudden death, but no cardiac event occurred in the other patients. In conclusion, exercise Thallium-201 myocardial scintigraphy showed a high prevalence (64%) of reversible perfusion defects in a group of patients with exercise-induced LBBB without any evidence of CAD at angiography or coronary spasm at ergonovine test. Moreover, follow-up showed a relatively low rate of major cardiac events.

Exercise testing is an important noninvasive method for the exposure of arrhythmias. It provides complementary information to that obtained from ambulatory monitoring or electrophysiologic testing. By producing a number of important physiologic changes, especially activation of the sympathetic nervous system and an increase in circulating catecholamines, exercise testing provides a more complete assessment. On continuous monitoring, exercise-induced ventricular premature beats may be found in up to 34% of healthy subjects, in 60 to 70% of those with heart disease and in all patients who have experienced sustained ventricular tachycardia. Couplets or nonsustained ventricular tachycardia can be found during exercise in 0 to 6% of healthy subjects, in 15 to 31% of patients with heart disease and in 75% of those with sustained ventricular tachycardia. Even in patients with heart disease, there is only a small risk of inducing sustained ventricular tachycardia or ventricular fibrillation during exercise. The prognostic relevance of exercise-induced ventricular arrhythmias in patients with coronary artery disease or cardiomyopathy has not been clearly established. There appears to be an increased risk, however, in patients with ventricular premature beats as well as ST-segment depression or in patients with repetitive forms of ventricular arrhythmias during exercise which cannot be medically controlled. In healthy subjects, exercise-induced ventricular premature beats are of no prognostic relevance. In particular, for patients in whom arrhythmias are induced by exercise, exercise testing should be used to assess the effectiveness of antiarrhythmic drug treatment. Importantly, serious cardiac toxicity, often not observed at rest or during routine activities, may become apparent during exercise testing. It should be a standard part of arrhythmia assessment and management.

The behavioral studies component of the multicenter Cardiac Arrhythmia Pilot Study (CAPS) was designed to examine the relation of biobehavioral factors and frequency of ventricular premature complexes (VPCs), efficacy of antiarrhythmic therapy, and disease end points in a study population that had experienced recent myocardial infarction and significant ventricular ectopy. Biobehavioral factors included both psychosocial (depression, anxiety, social support, type A behavior, mood, defensiveness, and anger expressiveness) and psychophysiological (heart rate and blood pressure reactivity to a videogame stressor) variables. Data were collected at baseline and at 3-, 6-, 9-, and 12-month follow-ups. Of the 502 patients enrolled in CAPS, 353 participated in the behavioral studies component. At baseline, assessments of psychosocial variables revealed the CAPS study population to be generally similar to other heart disease populations, and no relation between these variables and psychophysiological reactivity or arrhythmias was found. At follow-up among patients assigned to the placebo condition, biobehavioral variables were not related to levels of VPCs or VPC suppression. Cox regression analyses revealed that type B behavior, depression, and reduced heart rate reactivity were associated with increased clinical events, even after controlling for baseline left ventricular ejection fraction, myocardial infarction before the qualifying event, use of beta-blockers, use of digitalis, Q wave of qualifying myocardial infarction, and presence of unsustained ventricular tachycardia on baseline electrocardiogram. It is hypothesized that the relation among reduced heart rate reactivity, depression, and clinical events is mediated by diminished cardiac vagal tone.

Determining safe and effective antiarrhythmic therapy in paediatric patients requires definition of the mechanism of the arrhythmia, determination of associated risk factors for treatment (such as the presence of congenital cardiac defects, myocarditis or cardiomyopathy), and monitoring for potential drug side effects related to the treatment. A number of modalities for non-invasive evaluation of arrhythmias is available, including ECG, 24-hour ambulatory Holter monitoring, and transtelephonic ECG transmission. Arrhythmias requiring medical treatment in children with normal cardiac anatomy and function include supraventricular tachycardia (SVT), ventricular tachycardia (VT) and primary atrial tachycardias. SVT is treated acutely with vagal manoeuvres or drugs which slow AV conduction [adenosine (adenine riboside), edrophonium, phenylephrine or verapamil]. When medical conversion is not achieved, transoesophageal overdrive pacing or direct current (DC) cardioversion may be required. Long term drug therapy for SVT includes first-line treatment with digoxin, verapamil or propranolol. Ventricular tachycardia is managed acutely with DC cardioversion and intravenous lidocaine (lignocaine). Chronic drug regimens include mexiletine, propranolol or amiodarone. In children with structural congenital heart disease or myocardial dysfunction, hazards of drug therapy for arrhythmias include depression of cardiac function, proarrhythmia (drug-induced worsening of arrhythmias), and conduction abnormalities. Care must be taken to choose medication regimens which are likely to be effective with minimum risk of potentiating abnormal haemodynamics or conduction.

Multiple lead systems are shown to have a higher sensitivity than that of single leads for detecting coronary artery disease (CAD) during exercise testing, but the value of ST-segment depression isolated to the inferior leads is questionable. To ascertain the diagnostic accuracy of inferior limb lead II compared with that of precordial lead V5, a retrospective analysis of 173 men was performed (108 in a training population and 65 in a validation cohort). All patients had a standard exercise test and underwent diagnostic coronary angiography within 15 days of the exercise test (range 1 to 65). Sixty-three patients had greater than or equal to 1 coronary stenoses greater than or equal to 70%, or left main lesion greater than or equal to 50%, whereas 45 patients in the training population did not. Exclusion criteria were female sex, left ventricular hypertrophy, left bundle branch block or resting ST-segment depression on the baseline electrocardiogram, previous myocardial infarction or revascularization procedures, and any significant valvular or congenital heart disease. Lead V5 had a better combination of sensitivity (65%) and specificity (84%) (chi-square = 24.11; p less than 0.001) than that of lead II (sensitivity 71%, specificity 44%) (chi-square = 2.25; p = 0.13) at a single cut point, and this improved specificity was substantial (95% confidence interval for observed difference 22 to 58%). Receiver-operating characteristic curve analysis also revealed that lead V5 (area = 0.759) was markedly superior to lead II (area = 0.582) over multiple cut points (z = 3.032; 2p = 0.002).(ABSTRACT TRUNCATED AT 250 WORDS)
