Every year there are potentially more than 500 sudden unexplained deaths in England, reveals a nationwide study published ahead of print in the journal Heart.
This figure is around eight times higher than previously thought, the data suggest.
The research team drew on cause of death judgments relating to sudden unexplained deaths in people from 117 coroners (out of 122) across England between October 1997 and May 1999.
The judgments were all based on post mortem examination reports. None of those who died had a history of heart disease, and they had all last been seen alive within 12 hours of death. All were aged between 4 and 64. Each case was assessed by an expert to eliminate other identifiable causes of death.
National figures for SADS (sudden adult death syndrome) were calculated and compared with official death statistics for SADS and unknown causes of death,
The results showed that only around a third of the 56 cases of SADS were correctly identified. Causes of death had been attributed to heart attack or other causes, such as epilepsy and drowning.
SADS cases tended to be young, with an average age of 32. But their ages ranged from 7 to 64. Almost two thirds (63%) were male.
Four had had some heart symptoms in the 48 hours before death, and two thirds had experienced cardiac symptoms at some point in the past..
Futhermore, almost one in five (18%) had a family history of sudden unexplained deaths before the age of 45.
Initially, the authors calculated that the total annual numbers of SADS cases per 100,000 of the population was 0.16. But official statistics for unknown causes of death were 1.34 per 100,000, up to eight times higher than initially estimated.
The authors say that this equates to more than 500 such deaths every year in England .
Families affected by SADS have an inherited genetic heart defect, which makes them prone to severe abnormalities in heart rhythm, and sudden death, suggest the authors.
SADS should be a certifiable cause of death, which should prompt automatic screening of other family members, they contend.

Over 500 Sudden Unexplained Deaths Every Year, Mostly In Young Men
英国每年有500例以上不明原因猝死，多为青年男性
Every year there are potentially more than 500 sudden unexplained deaths in England, reveals a nationwide study published ahead of print in the journal Heart.
英国每年可能有500例以上不明原因猝死，这引起了全国范围的研究，这些研究在尚未印刷以前就在《Heart》杂志上进行了发表。
This figure is around eight times higher than previously thought, the data suggest.
数据表明，这个数字大约比以前人们设想的八倍还要高。
The research team drew on cause of death judgments relating to sudden unexplained deaths in people from 117 coroners (out of 122) across England between October 1997 and May 1999.
在1997年10月和1999年5月之间，研究小组从英国122名法医当中的117名法医那作出了人们死因是不明原因猝死的判断。
The judgments were all based on post mortem examination reports. None of those who died had a history of heart disease, and they had all last been seen alive within 12 hours of death. All were aged between 4 and 64. Each case was assessed by an expert to eliminate other identifiable causes of death.
这些判断全是建立在死后检查报告基础上的。猝死的人均无心脏病史，均有人在他们猝死前的12小时内看到过他们。猝死的人年龄从4岁到64岁不等。每一例猝死均由专家评估以排除其它死因的存在。
National figures for SADS (sudden adult death syndrome) were calculated and compared with official death statistics for SADS and unknown causes of death,
计算了国内成年人猝死症（SADS）的数字并将其与官方报道的死于SADS和不明原因死亡的数据进行了比较。
The results showed that only around a third of the 56 cases of SADS were correctly identified. Causes of death had been attributed to heart attack or other causes, such as epilepsy and drowning.
结果表明56例SADS中约有三分之一情况完全相同。死因是心脏病或其它原因如癫痫或溺死。
SADS cases tended to be young, with an average age of 32. But their ages ranged from 7 to 64. Almost two thirds (63%) were male.
SADS倾向于年轻化，平均年龄为32岁。但是死者的年龄却是从7到64岁不等。将近三分之二（63%）的死者是男性。
