sudden cardiac death

Italian midfielder Piermario Morosini has died following a suspected heart attack on the pitch in Pescara, football officials say.

Ex-Italy under-21 footballer was playing for Livorno in the Serie B match at Pescara when he fell to the ground in the 31st minute.

A defibrillator was used and Piermario Morosini, 25, was taken to hospital. The game was halted with other players in tears.

All league games in Italy this weekend have been called off following Piermario Morosini’s death.

Piermario Morosini had been on loan to Livorno from the Serie A club Udinese.

He collapsed face down and appeared to be in convulsion. The referee’s assistant drew the referee’s attention and he stopped the game.

The footballer was taken to Pescara’s Santo Spirito hospital by ambulance, but he could not be revived.

Last month Bolton’s Fabrice Muamba was technically “dead” for 78 minutes after collapsing in an FA Cup tie.

The 24-year-old England player is now making “strong and steady improvements”.

Following Fabrice Muamba’s collapse, attention had been drawn to the situation for athletes in Italy, which has mandatory cardiac screening for all young people engaged in organized sport.

The charity Cardiac Risk in the Young says that the Italian measures have reduced the incidence of young sudden cardiac death in Italy by 90% in the 30 years since the screening was introduced.

US researchers have identified how the time of day can increase the risk of dying from an irregular heartbeat.

According to a study published in the journal Nature, the risk of “sudden cardiac death” peaks in the morning and rises again in the evening.

The study suggests that levels of a protein which controls the heart’s rhythm fluctuates through the day.

A body clock expert said the study was “beautiful”.

The inner workings of the body go through a daily routine known as a circadian rhythm, which keeps the body in sync with its surroundings. Jet lag is the result of the body getting out of sync.

As the chemistry of the body changes throughout the day, this can impact on health. The researchers say they have identified, in mice, how the time can affect the risk of sudden cardiac death.

They identified a protein called kruppel-like factor 15 (Klf15), which was controlled by the body clock and whose levels in the body went up and down during the day. The protein influences ion channels which control heart beat.

Genetically modified mice which produced too much Klf15 and those which produced none at all both had an increased risk of developing deadly disturbances in cardiac rhythm.

Prof. Darwin Jeyaraj, from the Case Western Reserve University School of Medicine, said: “Our study identifies a hitherto unknown mechanism for electrical instability in the heart.

“It provides insights into day and night variation in arrhythmia susceptibility that has been known for many years.”

There are important differences in the way that human and mouse hearts work, so it is unknown whether the same mechanism exists in people.

Fellow researcher Prof. Mukesh Jain said: “We are just scratching the surface. It might be that, with further study, assessment of circadian disruption in patients with cardiovascular disease might lead us to innovative approaches to diagnosis, prognosis, and treatment.”
