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

Giải thích: “intense research continues in the hope of further comprehending why and how heart failure is triggered” (nhiều nghiên cứu tiếp diễn với hy vọng hiểu rõ hơn tại sao và cách suy tim được gây ra).

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

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions from 30 to 34.

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-1980s 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 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.
