小心:心脏病更容易在早上发作

For example, blood pressure is at its highest in the morning and lowest at night, during sleep. Hormones such as cortisol, which increases blood sugar levels, are also in higher concentration in the morning. The body’s metabolism increases when we wake up, but at night it is comparatively slow.
例如，血压在早上时最高，而晚上睡觉时最低。激素如皮质醇，增加血糖水平，同样在早上浓度更高。早晨起床时体内的新陈代谢加速，但是晚上就相对较低。

The trend could also be explained by the fact some people suffering chest pain at night may try to wait until morning before getting help.
这种趋势也可以解释人们在晚上感到胸痛可能等到早上才去看病的事实。

Judy O’Sullivan, senior cardiac nurse at the British Heart Foundation, said: ‘This study provides some interesting observations. However further research is needed.
英国心脏基金会高级心脏护士Judy O’Sullivan说：“这个研究提供了一些有趣的观察结果。然而需要进一步的研究。”

 ‘Regardless of the time of day, the quicker someone having a heart attack is treated, the less the damage they will have, which is why it is essential that anyone who experiences heart attack symptoms should call 999 immediately.’
“无论什么时候，当病人心脏病发作时越快治疗，伤害就越少，这就是为什么有人心脏病发作必须马上拨打999。”

There is already compelling evidence that heart attacks are more common in the morning. In 2008 researchers in Cincinnati claimed the risk was four times as high compared with other times of the day.
已经有更加令人信服的证据证明心脏病发作在早上比较常见。2008年研究人员在辛辛那提大学称早上病发的风险是一天中的其他时间的4倍。
