The new technique assesses the biological age of the arteries through central pressure



Reading time: 2 minutes.

The speed at which the blood leaves the heart and the resistance of the arteries to the course of this blood are determined by the stiffness of the walls of these arteries. And this can be assessed through central pressure, a technique that uses pulse wave measurement generated by each heart attack.

This is a new weapon in the diagnosis / prevention of cardiovascular diseases. With this information, it is possible to determine the quality of the arteries, the biological era of the vessels, to predict and to choose treatments suitable for each patient.

Cardiologist Eduardo Costa Duarte Barbosa, president of the Latin American Association of Hypertension (LASh) and the Latin American Arterial Association (Arterios LATAM), the evaluation of this arterial elasticity is of clinical significance if he can better stratify the patient's risk factors and thus contribute to the treatment and preventing cardiovascular events responsible for more than 380,000 deaths in Brazil, according to the Cardiometer of the Brazilian Society of Cardiology, and about 18 million worldwide, according to C the veterinary health organization.

In Brazil, the central pressure measurement technology has already been confirmed by the National Food Supervision Agency (Anvisa), but several doctors still know the methods. However, according to cardiologist Eduardo Barbosa, recent studies have contributed to this new knowledge leading to a greater personalization of medicine.

"Studies have shown that this is a concept that can change the way patients deal with individual treatment with personalized treatments," says the expert, noting even more attention to patients with hypertension, overweight and type 2 diabetes, as they have more rigid vessels and more chance of heart attack.

Recipe for longevity

In 2009, the Australian biologist and professor Elizabeth Blackburn was one of the Nobel Prize winners in medicine thanks to the discovery of telomeres (pieces of chromosomes) and their relationship to aging. According to the scientist, the smaller the size of this genetic element, the greater the aging of the individual, which makes the telomeres serve as a parameter of the effects of age on the body.

The biologist, who works at the University of California, San Francisco, USA, joined psychologist Elisa Epel of the same institution to share the scientific knowledge that connects the integrity of telomeres with our habits and the way we approach life. The result is in the book The Secret of the Telescope, published in the country by Planet Publishing House.

During the award ceremony, a specialist compares them with a lace finish. "Imagine the connection of shoes as a chromosome, which carries our genetic information." The telesometer is the tip that serves as protection. When it gets worse, the genetic material becomes unprotected, and cells can not be restored properly, "he said.

Scientists also found that lifestyle changes can prevent such deterioration, such as regular physical activity, the abandonment of addiction to cigarettes and alcohol, and the growing healthier diet.
