초록

배경: 여성은 관상동맥 수술의 위험인자이고 관상동맥 우회술의 사망률도 여성이 남성보다 더 높은 것으로 보고되었었다. 그러나 장기 생존율에 대한 남녀 간 차이는 다양하다. 대상 및 방법: 1992년부터 1996년까지 일차적 관상동맥 우회술을 받은 147명(남 98명, 여 49명)의 환자들을 대상으로 하였다. 대부분의 환자들이 체외순환하에 좌측 속가슴동맥과 하지두렁정맥으로 관상동맥 우회술을 받았다. 성별에 따른 조기 수술결과 및 장기 생존율을 알아보고 성별 위험 인자를 찾아보았다. 결과: 여성군에서 수술 및 병원사망률은 없었으나 남성군에서는 3예(3.0%) 있었다. 평균 $138.5{\pm}23.0$개월의 추적기간 동안 여성에서 사망률이 더 낮았고(여성 10예, 20.4%, 남성 44예, 44.9%) (p=0.004), 여자에서 가장 많은 사망원인은 만성 신부전증(4예, 40%)이었으며 심장사망은 2예(20%)뿐이었다. 수술 후 여성군의 1년, 5년, 10년, 14년의 생존율은 각각 100%, $98.0{\pm}2.0%,\;81.2{\pm}5.6%,\;78.4{\pm}6.1%$로 남성군(각각 $93.9{\pm}2.4%,\;79.6{\pm}4.1%,\;60.2{\pm}5.1%,\;48.6{\pm}6.1%$)보다 매우 우수하였다(p=0.004). 수술 전 여성군의 좌심실 구혈률이 남성보다 더 우수하였으나 여성의 더 우수한 생존율에는 영향을 주지 못했다(p=0.15). 여성군의 장기 생존율에 영향을 주는 인자는 당뇨병(p=0.033)이었고 남성에서는 병변을 가진 혈관수(p=0.006)였다. 결론: 관상동맥 우회술을 받은 여성 환자들에서 장기 생존율은 남성보다 우수하며, 여성의 장기생존에 영향을 주는 인자는 심장질환보다는 동반 이환이었다.

Background: Female sex was known to be a risk factor for mortality after coronary bypass grafting (CABG), and women showed higher in-hospital mortality than men. Material and Method: Between 1992 and 1996, 147 consecutive patients (98 men and 49 women) undergoing CABG were included in the study. Most patients had undergone CABG with left internal thoracic artery and saphenous vein under cardiopulmonary bypass. We examined the influence of gender on survival after CABG and looked for risk factors for survival. Result: There was no in-hospital mortality in women, but 3 death (3.0%) in men. During the mean follow-up period of $138.5{\pm}23.0$ months, mortality was lower in women than in men (20.4% vs 44.9%, p=0.004), and the most common cause of death in women was chronic renal failure (40%). Survival in women at 1, 5, 10, and f4 years was 100%, $98.0{\pm}2.0%,\;81.2{\pm}5.6%,\;and\;78.4{\pm}6.1%$, respectively, which was better than in men (p=0.004). Although preoperative left ventricular ejection fraction was higher in women than in men, this did not affect early and long-term survival difference between two sexes (p=0.15). Risk factor for long-term survival in women was diabetes (p=0.033) and in men number of diseased coronary artery (p=0.006). Conclusion: Long-term survival after CABG was better in women than men. Risk factor for long-term survival in women was morbid disease rather than cardiac disease.
