女性更容易死于心脏搭桥手术(二)

2005-09-04 00:00

  布兰克斯坦表示,尽管这一研究发现使人更为冷静,但他们不会对那些确实需要做心脏搭桥手术的女性患者进行阻止。“对于很多女性来说,这个手术仍然是医治她们疾病的最好选择”。

  报道说,布兰克斯坦与其同事将这项最新研究成果发表在由美国心脏学会(American Heart Association)出版的《循环》杂志年度《心血管手术增刊》上。

  冠状动脉搭桥术就是在冠状动脉狭窄的近端和远端之间建立一条通道,使血液绕过狭窄部位而到达远端,犹如一座桥梁使公路跨过山壑江河畅通无阻一样。手术中所用的材料是来自于患者自身的大隐静脉、乳内动脉、胃网膜右动脉、桡动脉、腹壁下动脉等。

  Women Less Likely to Survive Heart Bypass Surgery

  Women are nearly twice as likely as men to die from complications of heart bypass surgery, and their typically smaller body size may be one of the reasons, according to a study published Tuesday.

  In a review of records for 15,440 patients who had undergone coronary artery bypass grafting (CABG), researchers found that 4.24 percent of women died during or immediately after surgery, versus 2.23 percent of men, a statistically significant difference.

  The main reasons for the gender gap were the higher rates of "traditional risk factors" among women, said lead study author Dr. Ron Blankstein. In general, the study found, women were older and more likely than men to have problems such as diabetes and advanced heart failure.

  But another factor was body size. Patients with a relatively smaller "body surface area" were at greater risk of dying from heart bypass surgery, and in general, women have smaller bodies than men.

  Body surface area is an indication of the size of a person's coronary arteries, and smaller vessels can make the surgery "technically more difficult," explained Blankstein, a cardiology fellow at the University of Chicago Hospitals.

  This fact, he and his colleagues speculate, may be why smaller body size was linked to poorer survival.
