men with angina 'at greater risk' 换狭心症的男人患心脏病“风-凯发k8官网

men with angina are much more likely than women to develop further serious heart problems, a study suggests.

调查显示，有狭心症的男人似乎比女人更容易发展至严重的心脏问题。

researchers found male patients were twice as likely to have a heart attack and almost three times as likely to suffer a heart disease-related death.

angina, a type of chest pain, is common and can be the first sign of heart disease - but the risks are unclear.

the study of uk patients, led by the national university of ireland, appears in the british medical journal.

angina is caused by ¹ supply of blood to the heart muscle.

recent estimates suggest that 4.8% of men and 3.4% of women ² over 16 in england have angina（咽狭炎，狭心症）.

in scotland, the figures are higher: 6.6% of men and 5.6% of women.

the irish team identified 1,785 patients in scotland who were diagnosed with angina between january 1998 and december 2001, and tracked their progress for five years.

they found being male, older and a ³ was associated with an increased risk of having a heart attack.

the same factors - along with ⁴ - were also associated with a higher risk of dying from heart disease.

men were also more likely than women to undergo（遭受，经历） angioplasty（血管成形术） to open up blocked ⁵, or to have coronary ⁶（冠状动脉） bypass surgery.

lead researcher dr brian buckley, based in galway, said the reasons why men appeared more at risk were unclear.

some believe the problem could be that men are less likely to follow medical advice following ⁷.

others suspect that men do not go to their doctor until their condition is more advanced.

women are also thought to receive some protection from the sex ⁸ oestrogen（性激素）.

dr buckley said: "we need to look at what the hell is happening here rather more closely than we have in the past.

"hopefully, our study has demonstrated that men are at more risk -so indisputably（无争论余地地）, that more research will take place looking at why."

he said the main message from the study was that people with angina should take steps to improve their lifestyle to minimise risk of more serious disease.

he said: "if you are diagnosed with angina, you should not panic - it won't necessarily end up in a heart attack - but you ought to take what the doctor says to you seriously, both in terms of taking medication and adopting a healthier lifestyle."

dr mike knapton, associate medical director of the british heart foundation, said the study was important because it was based on large numbers of people living in the community, rather than in a hospital setting.

he said: "it confirms that smoking and being ⁹（极肥胖的） greatly up your risk of dying from heart disease.

"this is good news for people living with angina, as it shows that it's never too late for them to change their lifestyles, or to stop smoking."

the research was carried out in ¹⁰ with the university of aberdeen.
