[Heart rate and blood pressure variabilities in mild to moderate hypertensive patients with or without left ventricular hypertrophy].

Aim Of The Study: To compare heart rate (HR) and blood pressure (BP) variability in hypertensives with or without left ventricular hypertrophy (LVH).

Methods: Thirty-three mild to moderate hypertensive patients, mean age 45 +/- 15 years, underwent an echocardiogram, a 24 hr ambulatory BP monitoring (ABPM), a 24 hr ECG monitoring and a continuous BP recording over 15 minutes both in supine and standing positions, by using digital plethysmography (Finapres device).

Statistical Analysis: non parametric tests.

Comparison of the diagnostic accuracy of different methods of measurement of heart rate-adjusted ST-segment depression during exercise testing for identification of coronary artery disease.

Within a population of 160 consecutive symptomatic patients who all had undergone catheterization (80 with > or = 1 stenosis > or = 50%), we compared the accuracy of different computerized measurements of the exercise-induced changes in ST-segment: (1) the standard criterion (> or = 0.1 mV flat/downsloping ST depression or > or = 0.15 mV upsloping depression, both 60 ms after the J point); (2) heart rate (HR)-adjusted ST-segment depression (ST/HR index measured at 0, 20, 40, 60, and 80 ms from the J point); (3) the HR-adjusted ST integral (ST/HR integral measured from 0 to 40 ms and from 40 to 80 ms after the J point).

[Architecture and epidemiology in gynaecology and obstetrics (author's transl)].

The authors, who are doctors, architects and hospital engineers, made every effort to work out the architectural rules that were imposed on them at one and the same time by the epidemiology, the humanization of the work and spread in a specialty that is becoming more and more specialised and most attractive; having consultations between the disciplines take place, as they have done when a new isolated building for the department of gynaecology and obstetrics was being planned. An original study was carried out using information about the flow rates of people and the coefficients of interest in the siting of the various departments on small models, and this allowed a spatial tridimensional programme to be worked out so that the structure could become something like an ideal building in which the different needs of the functional element, the human element, the preventive epidemiological element and also the economic and budgetary possibilities could come together. The thoughts and suggestions of the authors concerned with this building should help to develop new concepts in hospital architecture which are of interest for gynaecologists and obstetricians.
