Do energy drinks help or harm our hearts?


If you have heard about “Redbull”, “Monster”, or “Burn”, you may already know what I’m referring to. An energy drink is a carbonated beverage that contains caffeine and other energetic components such as taurine or ginseng and is intended to boost the drinker’s energy.

According to a study carried out by Dr. Matteo Cameli and a team of scientists from University of Siena, energy drinks could improve heart function, since after conducting a trial on 35 healthy people, the researchers discovered that that these beverages enhanced contractions of both the left and right ventricles of the heart, thus delivering a positive effect on myocardial function.  

However, it has been proved that over-consumption of energy drinks could lead to unusually high heart rates, increase of blood pressure and other heart issues. If the consumer has preexisting heart diseases, the effects could be more dangerous.

This was the case of Anais Fournier, a 14-year-old girl who died on 2011 after consuming 2 cans of Monster drink within a period of 24 hours. After her autopsy, it was concluded that the girl died of cardiac arrhythmia as a result of caffeine toxicity.  She had an inherited disorder that can deteriorate blood vessels.

Her death raised awareness alarmingly on the subject, since energy drinks contain unregulated amounts of caffeine. Several studies are being conducted in order to know the numerous effects of these beverages.

Take a look at NBC's Tom Costello report on the subject.

If you have tried energy drinks, what has been your experience?  Are they dangerous only if the drinker has a heart disease?

The Great East Japan Earthquake and Cardiovascular Deseases

We know you might get scared because of a tremor, or an earthquake, but did you know about the real impact this natural event can have on humankind?
A group of researchers, led by the Dr. Hiroaki Shimokawa explains how natural disasters can affect our heart, causing cardiovascular deseases.
He used The Great East Japan Earthquake (2011) as a reference to conduct a study, providing impresive figures about the rising of people that suffered from different kinds of cardiovascular desease after the earthquake.
Is important to say that in terms of natural disasters, Japan is not too different to Chile, so take a look to our presentation and draw your own conclusions.

Just a Blood Sample to Predict a Stroke!


As incredible as it seems, myocardial infarctions (MI), better known as cardiac arrests or heart attacks, might be no longer a matter of dreadful surprise; a study conducted by a group of scientists from San Diego, California demonstrated that the presence of Circulating Endothelial Cells—CEC’s, non-hematopoietic cells (i.e.: units that hold back hematogenesis, the formation of blood cells such as hemoglobin)—can be related to the possibility of an imminent cardiac arrest. In the next presentation, we are going to show you how different can be the information provided by the media from a scientific article on the same subject.
