[Action of sublingual nifedipine on left ventricular filling in hypertensive crisis].

UNLABELLED: We studied the left ventricular filling before and 15 minutes after sublingual absorption of one Nifedipine capsule in 33 untreated hypertensive patients (mean age: 68.6) without other cardiac disease and presenting an hypertensive access. This study was carried out with Doppler-echocardiography. Sample volume was set at the tips of mitral leaflets. The protocol included: early peak filling velocity (VE), atrial peak velocity (VA), mitral pressure half-time (T1/2), isovolumic relaxation time (TRIV), velocity time integral of total mitral curve (VTIT) and velocity time integral of atrial curve (VTIA). We also studied VE/VTIT ratio which has been correlated to peak filling rate/mitral stroke volume ratio in radionuclide angiography. RESULTS: [table: see text] The variations of VA/VE, VTIA/VTIT, VE/VTIT and T1/2 are statistically significant but decrease of TRIV is not significant. The arterial blood pressure decreases from 184/103 to 153/83 and cardiac rate increases from 81.8 to 87.9 beats/minute. CONCLUSION: On hypertensive emergencies sublingual nifedipine significantly improves rapid left ventricular filling without change of TRIV. Acceleration of cardiac rate is moderate.

The cervical aortic arch: a case with diffuse arterial dysplasia and neurocutaneous angiomatosis. A review of the subject.

The authors present a case of cervical aortic arch which was discovered in a child of 5 years. The association with a diffuse and major vascular dysplasia, mainly neuroectodermic, is worth reporting. Only 40 cases of this abnormality have been published up to now. The anatomic classification of the different types of cervical aortic arch is presented.

[Epidemiological profile of patients with myocardial infarction and normal coronary arteriography].

Of a total of 4,800 coronary arteriogrammes, 1,280 of which were carried out after myocardial infarction, 25 cases of proven infarction with normal coronary arteriography, confirmed by several "blind" interpretations, were retained. The interval between acute infarction and coronary arteriography was usually less than 6 months. The average age of the patients was 36.9 years, affecting more women than in classical coronary artery disease. The acute infarction was nearly always the first symptom. Cigarette consumption and hormonal factors is women were coronary risks factors of note. Ventricular sequellae were frequent, cardiac failure exceptional, exercise testing nearly always negative and occupational rehabilitation usually normal. It would seem that this affection is less serious than classical myocardial infarction due to atheroma probably because the non-infarcted myocardium is healthy, but the true prognosis of this type of coronary accident will only be revealed by long term studies. In the meantime the most useful investigations and the management of these patients are discussed.
