초록
목적 : 울혈성 심부전 환자에서 예후를 판단할 때는 수많은 지표가 있으나 아직 실용적이지 않고 시험단계에 있어 어디에서든지 저렴한 비용으로 측정할 수 있는 간단한 지표에 대한 필요성이 대두되었다. 이런 지표 중 최근 새롭게 주목받는 지표가 빈혈과 요산이다. 이에 저자들은 만성 심부전 환자를 대상으로 빈혈과 요산의 농도가 심부전의 악화 및 사망에 미치는 영향에 대해 알아보고자 하였다. 방법 : 2001년 8월부터 2002년 10월까지 순천향대학병원 순환기 내과에 울혈성 심부전의 진단명으로 입원한 109명을 대상으로 전향적으로 분석하였다. 전체 109명의 환자는 혈색소의 농도에 따라 세 개의 군[1군(혈색소 <30%, n=21명), 2군(혈색소 30%∼38%, n=49명) 및 3군(혈색소 >38%, n=39명)]과 요산의 농도에 따라 세 개의 군[I군(요산 <5.2 mg/dL, n=20명), II군(요산 5.2∼7.5 mg/dL, n=25명) 및 III군(요산 >7.5 mg/dL, n=20명)]으로 분류하였다. 일차 종료점은 심부전 악화에 의한 재입원 및 모든 원인에 의한 사망으로 하였다. 결과 : 혈색소에 따른 분류에서 재입원은 1군 57.1%, 2군 28.6%, 3군 15.4%로 세 군간에 유의한 차이가 있었고, 특히 남자에서 1군, 2군, 3군 각각 82.3%, 22.2%, 14.3%로 유의한 차이를 보였다. 혈색소에 따른 분류에서 사망률은 세 군간의 차이가 없었다. 요산에 따른 분류에서 재입원은 세 군간에 차이가 없었고, 사망률은 I군 5%, II군 8%, III군 35%로 유의한 차이를 보였고, 특히 남자에서 유의한 차이를 보였다. 결론 : 본 연구에서 남성에서 빈혈이 심할수록 재입원율이 높았고, 고요산혈증이 심할수록 사망률이 높았다.
Abstract
Backgroud : Serum uric acid (UA) and anemia could be a valid and useful prognostic marker of chronic heart failure (CHF). We investigated the relationship of anemia and UA with clinical outcomes in CHF patients. Methods : We analyzed 109 patients with congestive heart failure between August 2001 and October 2002 (age 67±15 years, follow-up 14±5 months). We distributed the patients into 3 groups according to hematocrit (Hct) level [Hct group 1 (Hct <30%, n=21), Hct group 2 (Hct 30~38%, n=49), Hct group 3 (Hct >38%, n=39)] and into 3 groups according to serum uric acid (UA) level [UA group I (UA <5.2 mg/dL, n=20), UA group II (UA 5.2~7.5 mg/dL, n=25), UA group III (UA >7.5 mg/dL, n=20)]. Primary end point were rehospitalization resulting from aggravation of CHF and all-cause of death. Results : Among the groups according to Hct level, readmission rates were 57.1%, 28.6%, 15.4%, respectively (p<0.05). Among men, readmission rates were 82.3%, 22.2%, 14.3%, respectively (p<0.05). No significant difference in death rate was observed among the 3 groups. Among the groups according to UA level, there was no significant difference in readmission rates. Death rates were 5%, 8%, 35%, respectively (p<0.05) and there was significant difference in death rate especially among male patients. Conclusion : In male patients, lower hematocrit level was associated with higher readmission rate and higher serum uric acid level was associated with death rate.(Korean J Med 68:638-646, 2005)
