Newly recognized feature of athlete's heart found to be more prevalent in black male athletes

19.04.2012
New study presented at the World Congress of Cardiology organized by the World Heart Federation

Dubai (19 April 2012): Left-ventricular hyper-trabeculation (LVHT) – a feature of certain cardiomyopathies (chronic disease of the heart muscle) – has been found to be more common in black, male athletes according to a new study presented today at the World Congress of Cardiology.

A study of 692 athletes carried out in the UK, found that LVHT was more prevalent in athletes compared with non-athletes (6.8 per cent compared with 0.4 per cent). None of the individuals with LVHT, however, fulfilled the diagnostic criteria for any form of cardiomyopathy. Moreover, LVHT was found to be significantly more common in afro-Caribbean (black) athletes than in other athletes (13.2 per cent versus 4 per cent).

Regular athletic training results in physiological adaptation of a person's heart structure and function. And while many functional changes have been identified, LVHT has not previously been recognized as a feature of "athlete's heart". Rather LVHT is a known feature of cardiomyopathy, which remains the commonest cause of exercise-related sudden cardiac death in athletes.

"The high prevalence of LVHT among athletes suggests that this may represent part of the spectrum of cardiac adaptations that are known to make up "athletes heart'," said Dr. Navin Chandra, St Georges University of London. "Given that LVHT is a feature of sudden cardiac death, its prevalence among athletes creates greater challenges for doctors trying to differentiate between athlete's heart and a serious medical condition, particularly in black male athletes where the prevalence is much higher."

Study design

The study was carried out from 2006-2011, during which time 692 athletes and 455 sedentary participants underwent cardiac evaluation that included ECG and echocardiography. Results were analyzed according to the European Society of Cardiology sports cardiology consensus.
About the World Congress of Cardiology

The World Congress of Cardiology Scientific Sessions (WCC) is the official congress of the World Heart Federation and is held every two years. Through the Congress the World Heart Federation offers an international stage for the latest developments in science and public outreach in the field of cardiovascular health. The WCC places emphasis on the complementary nature of science and public outreach and strives to spread the message that through individual, community and patient-care interventions, the growing epidemic of cardiovascular diseases can be prevented.

About the World Heart Federation

The World Heart Federation is dedicated to leading the global fight against heart disease and stroke with a focus on low- and middle-income countries via a united community of more than 200 member organizations. With its members, the World Heart Federation works to build global commitment to addressing cardiovascular health at the policy level, generates and exchanges ideas, shares best practice, advances scientific knowledge and promotes knowledge transfer to tackle cardiovascular disease – the world's number one killer. It is a growing membership organization that brings together the strength of medical societies and heart foundations from more than 100 countries. Through our collective efforts we can help people all over the world to lead longer and better heart-healthy lives.

Im Focus: A step towards controlling spin-dependent petahertz electronics by material defects

The operational speed of semiconductors in various electronic and optoelectronic devices is limited to several gigahertz (a billion oscillations per second). This constrains the upper limit of the operational speed of computing. Now researchers from the Max Planck Institute for the Structure and Dynamics of Matter in Hamburg, Germany, and the Indian Institute of Technology in Bombay have explained how these processes can be sped up through the use of light waves and defected solid materials.

Light waves perform several hundred trillion oscillations per second. Hence, it is natural to envision employing light oscillations to drive the electronic...

Im Focus: Freiburg researcher investigate the origins of surface texture

Most natural and artificial surfaces are rough: metals and even glasses that appear smooth to the naked eye can look like jagged mountain ranges under the microscope. There is currently no uniform theory about the origin of this roughness despite it being observed on all scales, from the atomic to the tectonic. Scientists suspect that the rough surface is formed by irreversible plastic deformation that occurs in many processes of mechanical machining of components such as milling.

Prof. Dr. Lars Pastewka from the Simulation group at the Department of Microsystems Engineering at the University of Freiburg and his team have simulated such...

Im Focus: Making the internet more energy efficient through systemic optimization

Researchers at Chalmers University of Technology, Sweden, recently completed a 5-year research project looking at how to make fibre optic communications systems more energy efficient. Among their proposals are smart, error-correcting data chip circuits, which they refined to be 10 times less energy consumptive. The project has yielded several scientific articles, in publications including Nature Communications.

Streaming films and music, scrolling through social media, and using cloud-based storage services are everyday activities now.

Im Focus: New synthesis methods enhance 3D chemical space for drug discovery

After helping develop a new approach for organic synthesis -- carbon-hydrogen functionalization -- scientists at Emory University are now showing how this approach may apply to drug discovery. Nature Catalysis published their most recent work -- a streamlined process for making a three-dimensional scaffold of keen interest to the pharmaceutical industry.

"Our tools open up whole new chemical space for potential drug targets," says Huw Davies, Emory professor of organic chemistry and senior author of the paper.
