Risk factors explain earlier heart attacks among South Asians

Higher levels of heart disease risk factors may explain why people native to South Asia tend to have heart attacks at a younger age, a Canadian-led international study on cardiovascular disease found.
The South Asian countries of India, Pakistan, Bangladesh, Sri Lanka, and Nepal account for about a quarter of the world's population and contribute the highest proportion of cardiovascular diseases compared with any other region worldwide.
Protective factors such as exercise were less common among South Asians than controls from other countries, the team said.
(CBC) For South Asians, the average age for heart attack is about 53 compared with 58 in other parts of the world.
"The reason why South Asians get heart disease at an earlier age is because they have a higher proportion of people with bad cholesterol and less good cholesterol," said the study's author, Dr. Salim Yusuf of McMaster University in Hamilton, Ont.
For the study in Wednesday's Journal of the American Medical Association, Yusuf and his colleagues looked at almost 30,000 people from many countries.
South Asians who had heart attacks were compared with those who hadn't and to people of other ethnicities who did or did not have heart attacks.
History of diabetes was also more common among the South Asians, the researchers found.
Risk factors for immigrants, too
Other risk factors for cardiovascular disease, such as smoking, lack of exercise and poor diet were generally the same for people of all ethnicities.
"The earlier age of acute myocardial infarction in South Asians can be largely explained by higher risk factor levels at younger ages," the study's authors concluded.
The cholesterol differences are probably biological, but poor diet doesn't help. In dishes such as curries, vegetables may be cooked so long that they lose their health benefits, and the cooking habits follow South Asians when they emigrate, Yusuf said.
"I think South Asian immigrants who have come to North America are at even greater risk of heart disease compared to those living in their home countries," said Yusuf. "The reason for this is that they're even more urbanized."
Everyone should eat healthy food, get enough exercise, not smoke and get checked out by a doctor, but the advice may matter more for South Asians, he added. http://www.cbc.ca/health/story/2007/01/16/saisa-heart.html

已向加拿大主导的心血管病的研究发现，高水平的心脏病风险因子可解释为什么出生在南亚的人在年轻时易患心脏病。
The South Asian countries of India, Pakistan, Bangladesh, Sri Lanka, and Nepal account for about a quarter of the world's population and contribute the highest proportion of cardiovascular diseases compared with any other region worldwide.
印度、巴基斯坦、孟加拉国、斯里兰卡和尼泊尔等南亚国家占大约世界人口的四分之一，并且心血管疾病比例比世界的其它任何一个地区都高。
Protective factors such as exercise were less common among South Asians than controls from other countries, the team said.
研究小组报告，像体育锻炼等预防心脏病的因素南亚与与其他国家相比更少
(CBC) For South Asians, the average age for heart attack is about 53 compared with 58 in other parts of the world.。
(CBC)对南亚人，心脏病发作平均年龄是53岁，而世界的其它地区是58岁。
"The reason why South Asians get heart disease at an earlier age is because they have a higher proportion of people with bad cholesterol and less good cholesterol," said the study's author, Dr. Salim Yusuf of McMaster University in Hamilton, Ont.
加拿大安大略省汉密尔顿的McMaster大学的Salim Yusuf讲：“为什么南亚人在年轻时易患心脏病是因为他们进食坏胆固醇的人口比例较高而进食好胆固醇的人口比例较低。”
For the study in Wednesday's Journal of the American Medical Association, Yusuf and his colleagues looked at almost 30,000 people from many countries.
为了星期三出版在美国医学协会杂志的研究，Yusuf和其同事对来自许多国家的30000人进行了研究。
