Assessment of myocardial ischemia by 12-lead electrocardiography and Frank vector system during coronary angioplasty: value of a new orthogonal lead system for quantitative ST segment monitoring.

The optimal number and placement of electrocardiographic (ECG) leads to detect myocardial ischemia induced by coronary balloon inflation was assessed by analyzing ST segment changes in the standard 12-lead ECG and Frank X, Y, Z leads at 90-s intervals during 34 consecutive coronary angioplasty procedures. Mean occlusion time during angioplasty was 218 +/- 65 s. Myocardial ischemia, defined as transient angina or ST segment deviation greater than or equal to 1 mm in at least one lead, occurred in 33 (97%) of the 34 procedures. The most sensitive single leads (V2 or V3) detected 17 (51%) of 33 ischemic episodes. The best dual-lead combinations (leads V2 and V5, leads a VF and V3 and leads V3 and Y) increased the sensitivity of 69% (23 of 33). The three-lead combination V2, V5, Y had the highest detecting power (78% [26 of 33]). The X, Y, Z leads by themselves had a sensitivity of only 60% (20 of 33). From this proposed orthogonal lead system (V2, V5, Y), which combines anteroposterior (V2), left to right (V5) and inferosuperior (Y) forces, the spatial ST vector magnitude was calculated and monitored during balloon inflations. A good correlation was observed between this ST vector magnitude and the sum of ST deviations on the standard ECG (r = 0.940, p less than 0.00001), and these data were reproducible over sequential balloon inflations. The results of the study suggest that this orthogonal lead system is of considerable value in the detection and quantification of acute myocardial ischemia and, in this respect, is more useful than the Frank orthogonal vector system.

Influence of the arterial blood pressure and nonhemodynamic factors on left ventricular hypertrophy in moderate essential hypertension.

In a group of 36 untreated patients with mild to moderate essential hypertension (office systolic and diastolic blood pressures (BPs) 160 +/- 3.4 and 102 +/- 1.5 mm Hg, respectively), a 24-hour ambulatory BP monitoring and determination of left ventricular (LV) mass index according to the formula of Devereux were performed. After an overnight fast, blood samples were taken for the determination of serum aldosterone, plasma renin activity and serum parathyroid hormone. Urinary catecholamines were sampled for 24 hours. LV mass index (143.7 +/- 8 g/m2) did not correlate significantly either with office systolic or diastolic BP. The correlation of LV mass index with mean 24-hour systolic BP (145 +/- 3 mm Hg) was statistically significant: r = 0.395, p = 0.026. However, the best correlation was obtained with mean 24-hour diastolic BP (90 +/- 3 mm Hg) with r = 0.500 (p = 0.004). Urinary catecholamines were not correlated with LV mass index. LV mass index correlated significantly with plasma renin activity (r = 0.346, p = 0.050), and aldosterone (r = 0.559, p = 0.001). There was a very significant correlation between LV mass index and parathyroid hormone (r = 0.719, p = 0.00001) even after adjustment for mean 24-hour systolic and diastolic BPs. These results clearly demonstrate that ambulatory BP determinants but not office BP parameters are well correlated with LV hypertrophy in essential hypertension. Nonhemodynamic factors are important determinants of LV mass as well. Besides the renin-angiotensin-aldosterone system, parathyroid hormone appears to play an important role in cardiac hypertrophy.

Influence of arterial blood pressure and aldosterone on left ventricular hypertrophy in moderate essential hypertension.

In a group of 36 untreated patients with mild-to-moderate essential hypertension (office systolic blood pressure [SBP] 160 +/- 3.4 mm Hg, office diastolic blood pressure [DBP], 102 +/- 1.5 mm Hg), 24-hour ambulatory blood pressure monitoring, and determination of left ventricular (LV) mass index according to the formula of Devereux were performed. After an overnight fast, blood samples were taken for the determination of serum aldosterone levels and plasma renin activity. Urinary catecholamine concentrations were assayed from 24-hour urine collections. Left ventricular mass index (143.7 +/- 8 g/m2) did not correlate significantly with either office SBP or office DBP. The correlation of LV mass index with mean 24-hour SBP (145 +/- 3 mm Hg) was statistically significant: r = 0.395, p = 0.026. However, the best correlation was obtained with mean 24-hour DBP (90 +/- 3 mm Hg) with r = 0.499 (p = 0.004). Urinary catecholamine levels did not correlate with LV mass index. In addition, LV mass index correlated significantly with plasma renin activity (r = 0.346, p = 0.050) and serum aldosterone levels (r = 0.559, p = 0.0009). There was a strongly significant correlation between LV mass index and serum aldosterone levels even after adjustment for mean 24-hour SBP (r = 0.496, p = 0.005) and DBP (r = 0.514, p = 0.004). These results demonstrate that ambulatory blood pressure determinations but not office blood pressure parameters correlate well with left ventricular hypertrophy in essential hypertension. Nonhemodynamic factors are important determinants of left ventricular mass as well.(ABSTRACT TRUNCATED AT 250 WORDS)

Isolated rheumatic carditis, a disease in search of diagnostic criteria.

We report a case of acute dilated cardiomyopathy with histologic proof of inflammatory myocarditis. Although immunosuppressive therapy seemed to induce the resolution of the inflammatory infiltrate, it had no effect on the clinical course. The diagnosis of isolated rheumatic carditis was considered because of the finding of a very high antistreptolysin O titre and lack of evidence for either viral disease, infection with group C and G streptococci or other causes of spuriously high titres of anti-streptolysin O. In view of our conclusion longterm chemoprophylaxis was instituted.

Blood pressure load determines left ventricular mass in essential hypertension.

In a series of 35 newly diagnosed, previously untreated patients (mean age 46 years) with mild to moderate essential hypertension, office blood pressure measurements, 24-hour ambulatory blood pressure monitoring, and determination of left ventricular mass index by echocardiography according to the formula of Devereux were performed. We aimed at correlating left ventricular mass index with systolic and diastolic office blood pressure, mean 24-hour systolic and mean 24-hour diastolic blood pressure, systolic and diastolic load. Left ventricular mass index did not correlate with office systolic and office diastolic blood pressure. On the contrary, all correlations with ambulatory blood pressure parameters and left ventricular mass index turned out to be significant (mean 24-hour systolic blood pressure: r = 0.344, P = 0.026; systolic load: r = 0.408, P = 0.020; mean 24-hour diastolic blood pressure: r = 0.490, P = 0.004; diastolic load: r = 0.504, P = 0.003). These results clearly demonstrate that ambulatory blood pressure determinants but not the office blood pressure parameters are well correlated with left ventricular mass index in mild to moderate essential hypertension. Blood pressure load is as important as mean 24-hour blood pressure in this regard.

Clinical and psychosocial predictors of recurrence in recovered bipolar and unipolar depressives: a one-year controlled prospective study.

Unipolar and bipolar patients with a chronic illness pattern were investigated to evaluate the relevance of clinical and psychosocial risk factors to predict subsequent recurrence. Self-esteem, social adjustment, social support and attributional style were assessed in 27 recovered bipolar patients, 24 recovered unipolar patients maintained on lithium or antidepressant prophylaxis and 26 healthy controls. They were further interviewed every 2 months in a 1-year period in order to diagnose affective episodes according to Research Diagnostic Criteria. Survival analyses and Cox's regressions demonstrated that being a unipolar patient and showing poor social adjustment were the strongest predictors of the occurrence of affective episodes. Self-esteem, social support, attributional style and clinical characteristics, such as age at illness onset, number of previous episodes or of previous hospitalizations and presence of affective disorder in first-degree relatives, were not found to be risk factors for further recurrence. This study stresses the importance of social adjustment in evaluating the outcome of affectively ill patients maintained on medication prophylaxis.

Attributional style and depression: a controlled comparison of remitted unipolar and bipolar patients.

Attributional style was investigated in remitted affective disorder patients (23 unipolars and 26 bipolars) and 26 non-psychiatric controls. We found a specific cognitive vulnerability in unipolars. Unipolars attributed negative events to causes that were more stable--but not more internal nor more global--than bipolars and controls, and did not attach more importance to these events. Attributional vulnerability seemed more apparent in patients with longer histories of depression.

Immigration and psychopathology: a clinical study.

Three groups of 342 Greek, Iberian and Belgian psychiatric patients were compared, matched for sex, age, and time of hospitalization in a university hospital in Brussels. Schizophrenia, schizoaffective disorder/atypical psychosis were diagnosed more among immigrant patients. Somatic anxiety, loss of libido, delusions and hallucinations were symptoms that clinicians observed more in immigrant than in native patients. Atypical symptomatology and change of diagnosis were more likely to occur among immigrant patients. A higher proportion of second generation immigrant patients had a diagnosis of schizophrenia than either the first generation or the Belgians. Male immigrant patients were prescribed anxiolytic drugs more frequently than male natives, but were less likely to be referred to psychotherapy. The authors query whether these findings derive from specificities in the use of psychiatric services and/or from biases in clinicians'attitudes towards patients of different ethnic origin.

Social adjustment and self-esteem in remitted patients with mood disorders.

Mood disorders are characterized by manic and depressive episodes alternating with normal mood. While social function is heavily impaired during episodes of illness, there are conflicting opinions about inter-episode function. The present paper focuses on self-esteem and social adjustment in remitted mood disorders patients. Patients with mood disorders (99 bipolar and 86 major depressive subjects, in remission) were compared with a group of 100 control subjects. The self-esteem scale (SES) and the social adjustment scale (SAS) were used to measure self-esteem and social adjustment, respectively, in both groups of subjects. Patients with mood disorder exhibited worse social adjustment and lower self-esteem than control subjects. These results strongly confirm previous observations of poor inter-episode function in patients with mooddisorder.

Localisation and risk factors of peripheral arterial occlusive disease in the female.

Peripheral arterial occlusive disease has been described frequently as a disease affecting predominantly men. There is only a few information available concerning peripheral vascular disease in the female. Therefore, the aim of the present study was to examine risk factors in relation to localisation and symptoms of peripheral arterial occlusive disease in female patients. A retrospective study has been performed in 48 female patients (52-82 years with a mean age 69.5 years). Finally 45 patients were witheld because they had all a doppler examination and an oscillography of the lower limbs. The majority of the patients, namely 22 patients (49%) had combined ileofemoral and distal lesions. There were 15 patients (33%) who had isolated distal lesions, while only 8 patients (18%) had isolated ileofemoral vascular lesions. With respect to the symptoms the population could be divided in three groups: 16 patients (36%) were asymptomatic, 19 patients (42%) had intermittent claudication and 10 patients (22%) had rest pain and necrosis. Smoking was not the predominant risk factor in this group. Diabetes mellitus seemed to enhance distal vascular lesions, while arterial hypertension, obesity and lipids were predictive risk factors in peripheral vascular disease in the female. A high incidence of cardiovascular disease (31 patients, 69%) and cerebrovascular disease (13 patients, 29%) was concomitant.

Relapsing digital ulcers.

A 72-years-old male patient is described who presented with relapsing, digital ulcers on both feet, accompanied by digital cyanosis ("purple toes"). All episodes occurred 5 months after starting coumarin treatment for chronic atrial fibrillation and low output failure. Massive mural thrombosis was discovered of the entire abdominal aorta. Because of the clinical picture, together with progressive renal failure and persistent eosinophilia, cholesterol embolization from an ulcerated atherosclerotic plaque within the mural thrombus was highly suspected. Besides the clinical presentation of our patient, the spectrum of cholesterol embolization is much wider. The role of coumarin therapy is still speculative. Numerous reports however, indicate a potential role in precipitating the syndrome. The only therapy available consists of removing the source whenever possible.

[Towards a systemic understanding of depression]. / Vers une compréhension systémique de la dépression.

This articles reviews current research investigating the role played by psychosocial factors in affective disorders. Besides individual vulnerability factors of cognitive or intrapsychic type, family dysfunctions appear to be related to onset and course of depressive symptomatology. These data should stimulate the development of systemic studies focusing on affective disorders.

Social adjustment and the course of affective illness: a one-year controlled longitudinal study involving bipolar and unipolar outpatients.

The association between social adjustment and recurrent affective episodes was examined in 27 recovered bipolar patients and 24 recovered unipolar patients who had been receiving maintenance treatment for at least 1 year. Social adjustment variables and psychiatric status were assessed by bimonthly interviews over the 1-year period using the Social Adjustment Scale (SAS) and the Research Diagnostic Criteria (RDC). Variations in the social adjustment scores were analyzed in the 2 months preceding the onset of a recurrent affective episode. Furthermore, social adjustment variables at entry into the study were assessed to investigate whether there was any association between these and the potential timing of a recurrent episode. Results revealed no significant deterioration in social adjustment during the 2 months preceding a recurrent affective episode. However, it was demonstrated that there was a relationship between a patient's overall social adjustment score at entry into the study and the onset of recurrent affective episodes, independent of any residual depressive symptomatology. Specifically, impaired work adjustment in bipolar and unipolar patients was associated with recurrent episodes. Impaired social and leisure activities adjustment in bipolar patients was also associated with recurrent episodes, and impaired marital adjustment in unipolar patients was associated with recurrent episodes. These results suggest that social maladjustment could be a risk factor for both unipolar and bipolar recurrent affective episodes and that impairment in specific areas of social functioning could be used to predict outcome.

Social adjustment of remitted bipolar and unipolar out-patients. A comparison with age- and sex-matched controls.

Various areas of social adjustment were compared using the Social Adjustment Scale in 27 remitted bipolars, 24 remitted unipolars and 25 normal controls matched for age and sex. Scores for global adjustment and for social and leisure activities were significantly worse in patients than in controls. The maladjustment in social and leisure activities appeared only in 'contact with friends' for bipolar patients and 'diminished social interactions' for unipolar patients. Unipolar patients differed significantly from controls on the items investigating sexual adjustment. In unipolars, social maladjustment seemed to be independent of the course of the disease; in bipolars, it was partly related to the mean number of lifetime episodes and current residual symptoms.

Psychosocial predictors of major affective recurrences in bipolar disorder: a 4-year longitudinal study of patients on prophylactic treatment.

A total of 21 recovered bipolar patients on prophylactic treatment were prospectively followed up for a period of 1 year. Data for major recurrences were retrospectively collected for an additional 3-year period. During the entire 4-year period, over half of the patients (52%) had no major affective recurrences. Eight patients experienced a major depressive episode, while only two experienced a manic one. Psychosocial and clinical variables were assessed at entry to the study. The effect of these variables on the subsequent 4-year illness course was analysed using survivorship curves. The results show that the following psychosocial variables significantly predicted the occurrence of a major affective episode: low level of social support, maladjustment in social and leisure activities, and poor quality of relationships with extended family. In contrast, clinical variables which characterize illness history were not significantly associated with major recurrences.

Life events and primary affective disorders. A one year prospective study.

BACKGROUND: Unipolar and bipolar patients with a chronic illness pattern were investigated to determine whether they experienced a higher number of life events prior to the onset of recurrent affective episodes. METHOD: The study participants consisted of 27 recovered bipolar patients, 24 recovered unipolar patients and 26 healthy control subjects. Life events and psychiatric status were assessed by bimonthly interviews over the period of one year using the Inventory for Recent Life Events and the Research Diagnostic Criteria. RESULTS: In both unipolar and bipolar patients, analyses revealed no significant differences in the number of life events experienced, irrespective of whether the patients had presented with a depressive episode of at least minor intensity during the study (all P > 0.1). Specifically, an increase in marital problems was observed in bipolar patients prior to the onset of recurrent hypomanic and manic episodes (P = 0.06). CONCLUSION: The causal association between life events and the onset of depression, shown to be relevant in non-chronically depressed subjects, does not apply in chronic affective disorders. In addition, our results suggest that marital events have an impact on the onset of recurrent hypomanic and manic episodes.

Self-esteem in recovered bipolar and unipolar out-patients.

The hypothesis of a low self-esteem in depressive patients was tested using the Rosenberg Self-Esteem Scale in 24 recovered unipolar and 27 recovered bipolar patients, compared with a normal control group of 26 subjects matched for age and sex. The hypothesis was confirmed only for unipolars; bipolar patients presented a self-esteem score not significantly different from normal scores. Self-esteem was not related to clinical characteristics of the affective disorder, suggesting that low self-esteem may be a basic component of a depression-prone personality. The investigation of the relationship between self-esteem and social adjustment confirmed the presence of social conformism in bipolar patients and rigidly set low self-esteem in unipolar patients. These results should stimulate the evaluation of different psychotherapeutic treatments in the long-term psychosocial management of affectively ill patients.
