[Predictive factors of normal coronary angiography].

The aim of this study is to compare two groups of patients Group A consisted of 120 patients (70 men and 50 women) hospitalised for anginal symptoms, with either clinical or electrical positive exercise test and/or ischemic events on a 24 H electrocardiography and having angiographically normal coronaries Group B consisted of 120 patients (102 men and 18 women) hospitalised for an acute coronary syndrome with pathological coronaries. The analysis of the 2 groups showed that in the group A the average age was lesser (56 years vs 60 years), women's percentage was higher (41% vs 15%) and cardiovascular risk factors were less frequent. Data from non invasive tests was significantly different in the 2 groups: the exercise test showed both clinical and electrical ischemic events in 35% of the patients in group A versus 75% in group B (p < 0.01) and the 24 h electocardiography showed ST depression in 9% of patients in group A versus 25% in group B (p < 0.01%). The coronary angiography is an invasive and an expensive procedure. The results of our study allow us to modulate its indications, especially in young women patients, with few or no cardivascular risk factors and with only electrical positive exercise test.

[Dumesnil's method: is it viable?].

BACKGROUND: Left ventricular (LV) ejection fraction (EF) is an indicator of left ventricular systolic function and is a potent predictor of cardiovascular mortality. LVEF is assessed by a variety of methods, however echocardiography is the most used in clinical practice. Simpson biplane multiple disc method (BMDM) is recommended by the American Society of Echocardiography; Dumesnil's method based on doppler echocardiography seems to be simpler and theoritically less influenced by distortion of LV geometry. OBJECTIVE AND METHODS: To assess the accuracy and reproducibility of Dumesnil's method a group of 100 patients proposed for coronarography with left ventricular angiography, prospectively underwent LVEF measurements by both BMDM and Dumesnil's method. RESULTS: Compared with LV angiography, the correlation coefficient for the Dumesnil's method was r = 0.85 and it was r = 0.9 for BMDM. Correlation in patients with LV regional asynergy were respectively r = 0.69 and r = 0.85. Intraobserver and interobserver variabilities were less then 7% for both echocardiographic methods. CONCLUSION: Although Dumesnil's method is less accurate than BMDM, it is simpler, more rapid with a satisfactory reliability and reproducibility.

[Contracted endocardial fibroelastosis in children: report of a case].

Endocardial fibroelastosis is un uncommon disease and it has a very bad prognosis since fatal evolution is usual before 2 years old. We report the case of a 20 years old woman who is affected with the contracted form of this disease associated with atrial septal defect (ASD) and mitral regurgitation. This disease was discovered by endocardial biopsy when she was 4 years old and underwent surgical resection of endocardial fibrosis, a patch on the ASD and mitral valve replacement. She was rehospitalised 15 years later with heart failure although continuous digitoxin therapy.

[Coxiella burnetti infectious endocarditis. Apropos of a case].

Chronic forms of Q fever (endocarditis) are rare, but are responsible for severe and desperately recurrent infections, resulting in multiple valve replacements with a reserved prognosis. The authors report the case of a 35-year-old patient with a known history of rheumatic fever, who developed blood culture negative infectious endocarditis on a mitral bioprosthesis. The diagnosis of Q fever was based on serological arguments. Despite long-term antibiotic therapy, serology remained strongly positive and was associated with repeated mitral valve disinsertion. The patient died immediately after the fourth operation in a context of haemodynamic failure. This clinical case emphasizes the importance of performing Q fever serology in any case of culture negative endocarditis and the therapeutic difficulties encountered in chronic recurrent endocarditis.

[Hydatid cyst of the heart of multivesicle type. Apropos of a case].

The authors report the case of a 30 year-old man on whom the diagnosis of hydatic cyst of the heart (HKC) was strongly suspected on bi-dimensional echocardiography and confirmed by surgery. This case is interesting because this HCH, completely latent clinically, was discovered by echocardiography performed in view of a localized infra-epicardic ischemia, the major contribution of bi-dimensional electrocardiography enabling to make a quick and easy anatomical and topographic diagnosis, the primary nature of this hydatic localization which does not affect any other organ, and finally the multivesicle aspect of the cyst, rather unusual in single localizations of hydatic cyst of the heart. A brief review of the literature is then presented.

[A clinical trial of a titrated Olea extract in the treatment of essential arterial hypertension].

A clinical assay of Olea europaea L. aqueous extract was carried on two groups of patients suffering with essential hypertension. 12 patients consulting for the first time, 18 patients with antihypertensive treatment. Treatment based on Olea europeae L. leaf aqueous extract was given (400 ng x 4/24 h) during 3 months, after 15 days treatment based on placebo. We note for all patients a statistically significant decrease of blood pressure (p < 0.001), we didn't find any modification of biological parameters excepted a significant little decrease of glycemia and calcemia p < 0.01 and p < 0.01 respectively. We didn't find any side effect in the two groups.
