Epidemiology and risk factors

05.09.2005


The fact that cardiovascular disease (CVD) is the number one killer of European women is still not widely known, nor is that women are disadvantaged in terms of risk assessment, diagnosis, prognosis and treatment.



CVD is the biggest cause of death in European women, accounting for 40% of all deaths- twice as much as all cancers combined. Coronary heart disease (CHD) and stroke together are TEN times commoner than breast cancer, yet many women -and indeed health professionals- appear unaware of this.

Risk of cardiovascular disease in both sexes is related to age, smoking, blood cholesterol level and blood pressure; while women develop CVD ten years after men, it is more lethal when it occurs one year after a heart attack (42% of women will be dead, compared to 24% of men). A woman with multiple risk factors loses her "age advantage" and may be at higher risk than a man the same age. Diabetes is a particularly potent risk factor in women.


Diagnosis and Treatment

Women are less likely to be investigated for heart disease, diagnosed correctly, referred for specialist investigation, offered revascularization, have adequate risk factor assessment or be offered appropriate drug therapy such as aspirin, beta-blockers and cholesterol lowering medication. They are seriously under-represented in therapeutic trials, resulting in a less adequate evidence base for treatment.

New Points from the Conference

  • Women are less likely to be offered percutaneous interventions (angioplasty and stents) than men and do less well when they do receive them. Underutilization of drug treatments has been confirmed.
  • Young female diabetics are at high risk, and have a disproportionately high mortality when they do get a heart attack.
  • Women who have an out of hospital cardiac arrest are less likely to survive than men.
  • Women with chest pain and apparently normal coronary arteries on coronary angiography may have severe atherosclerosis when assessed with intravascular ultrasound (IVUS). They develop more acute coronary syndromes (heart attacks and unstable angina) over follow-up than men.

Conclusions

There is a major need to communicate these findings to the public, health planners and indeed health professionals. More research is needed into the clinical presentation of CVD in women and why health professionals and indeed perhaps women themselves seem to underestimate the problem. Therapeutic trials planners need to recognize that CVD is, if anything, a bigger problem for women than men. New detection and management strategies are needed, and new recommendations on CVD evaluation, prevention and management need to reflect this new knowledge. Ultimately, as with all aspects of CVD prevention, the challenge is to "de-medicalise" the problem and make self risk assessment and management accessible to all from childhood on.

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

Im Focus: Fraunhofer ISE Develops Highly Compact, High Frequency DC/DC Converter for Aviation

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.

Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
