Tossing and turning at night could double the risk of a heart attack People who toss and turn in their sleep are twice as likely to suffer a heart attack, research suggests. Scientists said regular waking in the night should be seen as a warning of future ill-health.The study of nearly 13,000 people found that people who struggled to sleep through the night were 99 per cent more likely to suffer from heart attacks or severe angina. Those who took more than half an hour to fall asleep or got less than six hours of sleep a night were also at increased risk. The Japanese research did not establish why there were such a strong association between sleep and heart health. But scientists said that the act of constant waking might cause “overactivity” in the nervous system, which could raise heart the heart rate and blood pressure, placing extra strain on the heart. Poor sleep could also be a symptom of poor health, meaning that those with heart problems were less likely to get a decent night’s sleep. The research found people who took more than half an hour to fall asleep had a 52 per cent increased heart attack risk and 48 per cent increased risk of a stroke. And those who got less than six hours of sleep a night were 24 per cent more likely to have a heart attack.

Theo các nhà nghiên cứu, những người không muốn ngủ có nguy cơ mắc bệnh đau tim gấp đôi nguy cơ đau tim bình thường . Các nhà khoa học cho biết thức giấc thường xuyên vào ban đêm được xem như một lời cảnh báo về sức khoẻ không lành mạnh trong tương lai. Nghiên cứu gần đấy cho thấy rằng 13.000 người là những người phải vật lộn để ngủ vào ban đêm là 99% có nguy cơ bị đau tim hoặc đau thắt ngực nghiêm trọng. Những người mất hơn nửa giờ để ngủ hoặc ngủ ít hơn sáu giờ đồng hồ cũng có nguy cơ gia tăng bệnh . Nghiên cứu của Nhật Bản đã không xác định được lý do tại sao lại có một mối liên hệ mạnh mẽ giữa giấc ngủ và sức khoẻ của trái tim. Nhưng các nhà khoa học cho biết, hành động thức tỉnh liên tục có thể gây ra tình trạng "kích hoạt quá mức" trong hệ thần kinh, làm tăng nhịp tim và huyết áp, gây thêm căng thẳng lên tim. Ngủ kém cũng có thể là triệu chứng của tình trạng sức khoẻ kém, có nghĩa là những người có vấn đề về tim ít có khả năng ngủ ngon giấc. Cuộc nghiên cứu cho thấy những người phải mất hơn nửa giờ để ngủ có nguy cơ đau tim tăng 52% và 48% nguy cơ cơ thể bị đột quỵ tăng cao. Và những người có ít hơn sáu giờ để ngủ một đêm là 24 % nhiều khả năng bị đau tim.

Read the following passage carefully and then choose the best answer to  each question.

As heart disease continues to be the number-one killer in the United States, researchers have become increasingly interested in identifying the potential risk factors that trigger heart attacks. High-fat diets and "life in the fast lane" have long been known to contribute to the high incidence of heart failure. But according to new studies, the list of risk factors may be significantly longer and quite surprising.

          Heart failure, for example, appears to have seasonal and temporal patterns. A higher percentage of heart attacks occur in cold weather, and more people experience heart failure on Monday than on any other day of the week. In addition, people are more susceptible to heart attacks in the first few hours after waking. Cardiologists first observed this morning phenomenon in the mid-1980, and have since discovered a number of possible causes. An early-morning rise in blood pressure, heart rate, and concentration of heart stimulating hormones, plus a reduction of blood flow to the heart, may all contribute to the higher incidence of heart attacks between the hours of 8:00 A.M. and 10:00 A.M.

           In other studies, both birthdays and bachelorhood have been implicated as risk factors. Statistics reveal that heart attack rates increase significantly for both females and males in the few days immediately preceding and following their birthdays. And unmarried men are more at risk for heart attacks than their married counterparts. Though stress is thought to be linked in some way to all of the aforementioned risk factors, intense research continues in the hope of further comprehending why and how heart failure is triggered.

According to the passage, which of the following is NOT a possible cause of many heart  attacks?

A. decreased blood flow to the heart          

B. increased blood pressure

C. increase in hormones                    

D. lower heart rate

DỊCH BÀI

Khi bệnh tim là kẻ giết người số một ở Hoa Kỳ, nhà nghiên cứu đã ngày càng quan tâm tới việc xác định yếu tố rủi ro có thể xảy ra gây ra cơn đau tim. Chế độ ăn uống nhiều chất béo và" cuộc sống sôi động" đã được biết đến từ lâu như là nhân tố lớn góp phần tạo nên phạm vi ảnh hưởng của suy tim. Nhưng theo nghiên cứu mới, danh sách yếu tố rủi ro có thể dài hơn nhiều và hoàn toàn bất ngờ.

Suy tim, chẳng hạn, có vẻ có mùa và liên quan đến thời gian kiểu mẫu. Tỉ lệ phần trăm của cơn đau tim thường xảy ra khi trời lạnh, và vào ngày thứ hai hơn bất cứ ngày nào khác ngày trong tuần. Ngoài ra, mọi người dễ bị mắc bệnh đau tim hơn trong mấy giờ đầu sau khi thức giấc. Bác sĩ tim mạch đã quan sát hiện tượng này trong giữa năm 1980, và có từ khám phá ra một số nguyên nhân có thể. Sáng sớm tăng huyết áp, nhịp tim, và nồng độ tim kích thích hoóc - môn, cộng giảm của máu lưu thông đến tim, có thể tất cả góp phần tạo nên cao phạm vi ảnh hưởng của cơn đau tim giữa giờ 8:00 Sáng và 10:00 Sáng.

Ở nghiên cứu khác, cả sinh nhật lẫn sự độc thân bị ám chỉ là yếu tố rủi ro. Số liệu thống kê cho thấy là cơn đau tim tăng đáng kể cho cả phụ nữ và phái nam trong vài ngày ngay trước và sau ngày sinh của họ. Và đàn ông chưa vợ có nguy cơ cho cơn đau tim hơn phụ nữ. Cho dù áp lực được xem là có liên kết theo một kiểu nào đó với toàn bộ yếu tố rủi ro nêu trên, nhiều nghiên cứu tiếp diễn với hy vọng hiểu rõ hơn tại sao và cách suy tim được gây ra
