Identification of myocardial viability is of great clinical importance in patients with acute coronary events or chronic coronary artery disease. Stress echocardiography has emerged as a new accurate and cost-effective imaging modality to detect contractile reserve. Numerous studies have recently been published in this field. This article summarizes the main findings of these investigations and presents practical aspects of the method. [less ▲]

The authors report the case of a 50 year old man admitted to hospital with a right hemiplegia and aphasia of sudden onset in whom embolic fragments were found in the left mid and anterior cerebral artery territories at left carotid angiography : transoesophageal echocardiography demonstrated a protrusive plaque of atherosclerosis in the ascending aorta and a pediculated thrombosis in the descending aorta. Biological investigations revealed a protein S level of 3% (normal : 70-140%). This case illustrates the acute development of a thromboembolic phenomenon originating from the aortic arch in a patient with a coagulation defect. [less ▲]

In order to explain the opposite effect of 6,7-dihydroxylated isomers of 6, 7 - dihydrocanrenone on the urinary sodium and potassium excretion, we have tested the effect of these substances isolated from human urine on the Na(+)-K+ pump from different tissue preparation: rabbit kidney slices as well as NA-K ATPase purified from the kidney. Our results show an inhibition of pump as well as enzyme activity by the 6 beta 7 alpha isomer while the 2 other isomers are either uneffective or slightly stimulating. The 6 beta 7 alpha dihydroxy-6, 7-dihydrocanrenone could be one of the plasma ouabain-like substance incriminated in the pathogenesis of volume-expanded hypertension. [less ▲]

Between 1983 and 1988, thirteen patients (12 men and 1 women, average age 63 years) were operated in the acute phase of myocardial infarction for papillary muscle rupture (PMR). The rupture involved the posterior papillary muscle in 12 cases. The average left ventricular ejection fraction was 47 +/- 9 per cent (range 34 to 63%). Pulmonary capillary pressures ranged from 76 to 41 mmHg (average 35 mmHg). Eleven patients presented with acute pulmonary oedema and 7 had cardiogenic shock. Coronary arteriography showed triple vessel disease in 3 cases, double vessel disease in 7 cases and single vessel disease in 3 cases. Surgery was carried out on average 2.7 days after the rupture and 10 days after the initial infarct. In addition to mitral valve replacement (N = 13), 11 patients underwent a myocardial revascularisation procedure. The operative mortality was 15 per cent (N = 2). Papillary muscle rupture in the acute phase of myocardial infarction causes cardiac failure which is related more to the mechanical abnormality than to an alteration of left ventricular function. Considering the operative mortality and the natural history of PMR treated medically, the authors recommend early surgery as the only management which can improve the precarious haemodynamic status of patients with this complication.

Since Dahl's observation, a renal defect os sodium excretion is proposed as one of pathogenetic mechanism of hypertension (HTA). Our study has tried to verify this concept in 20 young normotensives with (n = 12) and without (n = 8) familial predisposition to HTA, allowing to test the genetic transmission of such potential renal abnormality of sodium balance. Each people was submitted to 3 different Na diet (20, 170 and 340 mM NaCl) each for 1 week. At each visit, blood pressure, vascular resistances, biological values were determined at rest (plasma renin activity, creatinine clearance, 24 hours before the test, catecholamines, aldosterone and ion urinary excretion). Then 1 liter of isotonic saline was perfused in 30 minutes with measures of blood pressure and 3 hours urinary dopamine and Na excretion. During the low and medium Na diets, but not during the high Na diet, the natriuresis and dopamine excretion were lower in the 3 hour urine collection in patients with a family history of HTA (p less than 0.02 and p less than 0.005, respectively). No other clinical or biological difference was noted between the 2 groups. Thus, genetic hypertensive predisposition seems to be characterized by a lower Na excretion during acute Na loading in normal or depleted Na diet, linked to an impaired urinary dopamine excretion. These findings suggest that the defect responsible for the susceptibility to sodium intake is at the kidney level. Some dopamine agonists would be of great therapeutical value in treating such patients when blood pressure begins to rise. [less ▲]

Five cases of Marfan's syndrome with cardiovascular lesions are presented. Among these five patients, two with type I aortic dissection, one with true aneurysm of the ascending aorta and one with aortic regurgitation underwent composite grafting of the ascending aorta according to the Bentall technique. The fifth patient died preoperatively, due to extensive dissection of the transverse aorta. Marfan's syndrome is transmitted in an autosomal dominant manner. Fifty percent of the patients die at a mean age of 32 years, and 95 p. 100 of the deaths are caused by cardiovascular lesions. These lesions predominantly affect the left cardiac valves (aortic or mitral regurgitation) and the ascending aorta. Except in emergencies, replacement of the ascending aorta by a composite graft must be envisaged in subjects with Marfan's syndrome presenting with aortic regurgitation and dilatation of the aortic root.

The lack of effect of treatment of mild hypertension on the coronary heart disease has motivated researches for a better diagnosis of hypertension. One of the approaches presently under study uses the recording of ambulatory blood pressure using semi-automatic devices. The usefulness of these apparatus is however restricted by the lack of reference values recorded in normotensive control patients. We have recorded ambulatory blood pressure (PAA) in 24 normotensives, 22 untreated hypertensives and 45 treated hypertensive patients, and compared the data obtained to the blood pressure recorded during medical examination (PAC). If a good correlation is usually observed between PAA and PAC, very large and unpredictable discordances are frequently observed. No correlation is found between the difference PAA-PAC and the variability of PAA. This variability does not fully explain the difference observed between PAA and PAC. This variability expressed in mmHg increases with age and the level of BP. Ambulatory BP appears to be a very reproducible value which may allow to improve the definition of hypertension and therefore the cardiovascular risk. [less ▲]

De nombreux auteurs [l , 2, 3, 4] ont montré l'existence d'une activité inhibitrice plasmatique de la Na-K ATPase de type digoxine chez les patients urémiques ou hypertendus essentiels, principalement à activité rénine basse. Cette activité tend à disparaître lors de la déplétion sodée, suggérant que la variation de la balance hydrosodée est un des mécanismes de régulation de la sécrétion de ce ou ces facteur(s) plasmatique(s). Notre étude a été conçue dans le but de vérifier l'existence de cette activité chez des normotendus sains et de rechercher son rôle exact dans la régulation de la balance sodée et son influence sur la paroi vasculaire.

Two cases of Prinzmetal angina with normal coronary arteries are reported: coronary spasm was demonstrated in the left anterior descending artery in the first, and in the right coronary artery in the second case. Invalidating angina persisted despite maximal medical treatment with nitrite derivatives, nifedipine, verapamil and amiodarone. Homolateral thoracic sympathectomy led to long term remission of symptoms in one case and a short remission in the other, who then had to undergo complete denervation by plexectomy. Two hours after reoperation a refractory spasm of the right coronary artery led to the death of the patient. The possible causes of refractory coronary spasm and possible therapeutic approaches are discussed with reference to these cases. [less ▲]
