Stress: Decreasing the risk

20.09.2007
The importance of a healthy lifestyle to reduce stress in order to manage risk factors associated with adverse cardiovascular outcomes is emphasised in a Review in this week’s edition of The Lancet.

Dr Daniel Brotman, Johns Hopkins Hospital, Baltimore, MD, USA and colleagues studied relevant literature published between 1990 and 2006 to prepare the Review. They say: “Since antiquity, people have been intuitively aware of the connection between the heart and emotional stress.”

They examine the effect of stress on the sympathetic nervous system, stress physiology, and cardiovascular effects of stress, saying: “Acute physical stressors such as surgery, trauma, and intense physical exertion are well-known triggers of cardiovascular events. Emotional stressors are increasingly recognised as precipitants of such events.” They refer to an earthquake in Los Angeles in 1994, in which the number of cardiac deaths in the area in individuals who did not undergo direct physical trauma or increased physical exertion was two to five times the normal rate.

Also studied in the Review are subacute and chronic stressors. Major life changes are associated with psychological/emotional adjustment can increase the risk of cardiac events – eg. in the months following the death of a spouse, mortality from all causes, particularly cardiovascular ones, is increased. The authors say: “Similarly, the fear in the USA subsequent to the terrorist attacks on the World Trade Centre in New York in 2001 resulted in a rate of defibrillator firings of two to three times normal during the month after the event.”

The authors look at why individuals experience different responses to stress, and why cardiovascular events related to stress are more prevalent in the early morning than at other times – the reasons for this may include daily fluctuations in stress hormones and endothelial dysfunction.

They also comment on the lack of evidence to support the efficacy of behavioural and psychological stress reduction in the prevention of cardiac events. Such techniques are currently being studied in controlled clinical trials.

In conclusion, the authors say that stress is clearly an important – and potentially modifiable – risk factor for acute and chronic adverse cardiovascular disorders, and that effective medications are already in use. They say: “Ample evidence exists for a strong and consistent association acute and chronic psychological stress with cardiovascular risk factors….physicians should remain cognisant of the cardiovascular risk associated with chronic mental illness and psychological stressors, should take seriously patient symptoms (such as chest pain) which arise in conjunction with negative emotions, and should help their patients to alleviate unnecessary psychological strain, by advising that a healthy lifestyle should include stress reduction, anger management, and treatment of mental illness.”

Im Focus: Dresdner scientists print tomorrow’s world

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.

The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Im Focus: Three Magnetic States for Each Hole

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".

Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
