How Much Hypertension Can Be Affected By Daytime Stress?

20.11.2002


A group of Italian investigators led by Drs Francesco Fallo (Department of Medical and Surgical Sciences, University of Padova) and Dr Nicoletta Sonino (Department of Mental Health, Padova) explores a neglected issue: the relationship between daytime stress and the physiological lowering of blood pressure which should occur during sleep (dipping).



Scarce data are available on the influence of psychological aspects on 24-hour ambulatory blood pressure patterns either in normotensive or hypertensive subjects. This study was designed to evaluate the relationship between psychological profile and changes in daytime/nighttime blood pressure rhythm. Nocturnal dipping was defined as the night/day ratio of ambulatory mean systolic and/or diastolic blood pressure 0.87.

Three-hundred and two outpatients underwent 24-hour ambulatory blood pressure monitoring. They were administered a self-rating scale, the Psychosocial Index, as an indicator of stress, psychological distress, sleep disturbances, well-being, abnormal illness behavior and quality of life.. Patients were divided according to the presence (n = 125) or absence (n = 177) of night blood pressure dipping.


Dippers had lower (p < 0.001) nocturnal systolic and diastolic blood pressure than nondippers, and higher (p < 0.05) daytime diastolic blood pressure. Patients with nocturnal blood pressure decline had a markedly higher (p < 0.001) level of stress than nondippers. When the sample was divided according to the presence or absence of hypertension, only subjects with normal blood pressure showed nocturnal dipping associated with increased stressful life circumstances. The findings indicate that dippers experience stressful life circumstances, both in terms of life events and chronic stress. This suggests that stress-reducing techniques may be particularly helpful in the setting of hypertension characterized by nighttime blood pressure dipping.

Im Focus: Making lightweight construction suitable for series production

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.

Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...

Im Focus: Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.

"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Im Focus: A Quantum Low Pass for Photons

Physicists in Garching observe novel quantum effect that limits the number of emitted photons.

The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
