An underlying heart condition may be the cause of sudden deaths in sport events. (Health Xchange)
Just four days after English Premier League midfielder Fabrice Muamba suffered cardiac arrest during an English FA Cup match, Indian footballer Venkatesh suffered a similar fate during a match in Bangalore, India.
The 27-year-old Venkatesh, who was playing in a district level league match on March 21, collapsed on the field during the back end of the match.
While 23-year-old Muamba is in hospital in London recovering from his mid-match cardiac arrest, Venkatesh did not survive.
In a similar incident in Singapore a week earlier, 19-year-old Temasek Polytechnic student Muhammad Khairil Muhamad Nizam suddenly collapsed halfway through a friendly football match.
He was rushed to the hospital in an unconscious state but didn't survive. While investigations are underway into his death, initial reports indicated that he had died of heart failure.
There have been other previous sudden death incidences related to sports in Singapore. Last year, a 22-year-old Singaporean runner, Malcolm Sng Wei Ren, collapsed and died during the Standard Chartered Marathon Singapore.
What can explain such unexpected deaths?According to doctors, these sudden deaths in otherwise healthy and fit sportsmen may be explained by an underlying heart problem, compounded by vigorous physical exertion.
Dr Reginald Liew, consultant at the Department of Cardiology and deputy director of the research and development unit at the National Heart Centre Singapore (NHCS) said an underlying heart problem could include:
- a heart muscle disorder (e.g. abnormal thickening of heart muscles)
- an electrical problem (e.g. abnormal heart rhythm)
- an infection weakening the heart muscle
- a congenital abnormality of the coronary arteries
"The first two of these causes often have a genetic predisposition, meaning they may be related to certain mutations," Liew said. Given the appropriate stimuli and triggers, all four scenarios, he explained, could result in ventricular fibrillation: the heart ventricles don't contract properly, which may cause the heart to stop suddenly.

Who's at risk?Sometimes, the victim is found to have a family history of sudden death. But sudden cardiac arrest can also occur in healthy individuals without any known pre-existing heart issues and with no known family history of sudden death.
Liew added that there are screening tests available for the detection of heart muscle diseases and heart electrical disorders. For example, an echocardiogram can detect the former, and 12-lead ECG, the latter.

What can you do to lessen your risk of heart disease?
- Have your cholesterol levels checked once a year. Excess cholesterol can cause the blood flow to the heart to become blocked or reduced.
- Get your blood pressure checked yearly. If your blood pressure is persistently above 140/90mmHg and left untreated, it can result in damage to the heart and blood vessels.
- Control your diabetes and monitor your blood sugar levels.
- Lose excess body fat, especially around the waist.
- Exercise regularly to help prevent heart and blood vessel disease. Just check with your doctor first if you have known coronary artery disease or if you're above 40 years of age and have been inactive.
- Quit smoking. Smokers have two to three times the risk of non-smokers of sudden cardiac death. In fact, smokers account for about 40 per cent of deaths caused by heart disease in patients who are younger than 65 years.
- Manage your stress. Prolonged stress may contribute to a heart attack. Emotional stress and tension also cause the body to produce adrenaline, which makes the heart pump faster and harder, and may also cause the blood vessels to narrow down.

All the junkfoods and chemically-laced preserved food stuck in the guts for years and mutated into toxins and re-introduce to the blood via the intestinal villi - this is a more probable cause of most of the diseases including sudden death as the "toxins" can mutate into so many possibilities ie: cholesterol, uric acid, assorted bad bacteria: some of these that are cancer-forming. So clean your guts and plugged your mouth from junks (creation of men) and seafoods and eat natural (boiled, raw juiced, natural fruits, veggies, rootcrops) and you will never go wrong. Take it from God - (1Timothy 4:4) "For every creature of God is good, and nothing to be refused, if it be received with thanksgiving.."
Cardiac Doctors always have the last say!? Why not specialists in Lung illnesses and weak conditions? I know of a young man who died because of a torn lung? Due to disconnected or poorly co-ordinated growth which implicates hormonal effects in genetically modified food?
