Abstract

Background/Aims: The objective of this study was to observe changes in the clinical patterns of Korean patients over 65 years of age who received percutaneous coronary intervention (PCI) in the past 10 years. Methods: In total, 3,209 patients over 65 years of age [male:female; 1,950 ($71.4{\pm}5.21$ years):1,259 ($72.5{\pm}5.47$ years)] who underwent PCI between June 1999 and June 2009 were divided into four groups according to time period. Clinical characteristics, gender differences, coronary angiographic findings, and major adverse cardiac events (MACE) during a 1-year follow-up period were compared among the four groups. Results: The gender ratio was male-dominant and no significant change was observed over the observed time period [male (60.8):female (39.2%)], but the age increased [1999-2001:2002-2004:2005-2007:2008-2009=$71.2{\pm}5.11$ : $71.4{\pm}5.26$ : $71.9{\pm}5.25$ : $72.6{\pm}5.57$ years; p=0.001]. The prevalence of hypertension increased over time (p=0.028), but smoking decreased (p=0.002). Hypertension was the major risk factor for males, whereas obesity was the major risk factor for female patients. MACE-free 1-year survival increased over the observed period (p=0.014). Males had higher survival rates than females (p=0.007). MACE developed in 105 (3.27%) patients during the 1-year follow-up period and predictive factors for the development of MACE were being female (p=0.001), old age (p=0.008), hypertension (p=0.049), diabetes mellitus (p=0.004), smoking (p=0.009), and low Thrombolysis In Myocardial Infarction (TIMI) flow (p=0.048) by a multivariate analysis. Conclusions: The age of elderly patients undergoing PCI and the prevalence of hypertension increased, whereas smoking decreased over the last 10 years. Predictive factors for patients developing MACE during the one-year follow-up were associated with female gender, hypertension, diabetes mellitus, smoking, old age, and low TIMI flow.

목적: 우리나라에서 허혈성 심장 질환의 유병률이 높아지고 있으며, 관상동맥 중재술(percutaneous coronary intervention, PCI)이 중요한 치료 방법의 하나로서 시행되고 있다. 본 연구를 통하여 최근 10년간 PCI를 시행받은 65세 이상의 고령환자들의 임상양상의 변화를 확인하였다. 방법: 1999년 6월부터 2009년 6월까지 PCI를 시행받은 65세 이상의 3,209명[남성:여성 1950명($71.4{\pm}5.21$세):1,359명($72.5{\pm}5.47$세)]의 환자를 대상으로 하여 기간에 따라 4개의 군으로 나누었다. 네 군 간의 임상적 특징, 성별 간의 차이, 관상동맥 조영술 및 PCI 소견의 차이, 시술 후 1년 이내 주요 심장 사고의 발생을 분석, 비교하였다. 결과: 지난 10년간 PCI를 시술 받은 고령 환자의 성비는 지속적으로 남성의 비율이 높았다[남성(60.8%):여성(39.2%)]. 평균 연령은 지속적으로 증가하였으며, 위험인자의 경우 고혈압의 유병률은 증가하였으며(p=0.028), 흡연은 감소하였다. (p=0.002). 1년 이내 주요 심장 사고의 발생률은 지속적으로 감소하였으며(p=0.014), 남성은 여성보다 높은 생존율을 보였다(p=0.001). PCI 후 1년 이내의 주요 심장 사고는 105명(3.27%)에서 발생하였다. 주요 심장 사고의 발생 예측인자로는 여성(p=0.001), 75세 이상의 고령(p=0.008), 고혈압(p=0.049), 당뇨병(p=0.004), 흡연(p=0.009), 시술 후 낮은 TIMI flow (p=0.048) 등이었다. 결론: PCI를 시술 받은 고령 환자의 평균 연령은 지속적으로 증가하였으며, 고혈압은 지속적으로 상승하였고, 흡연은 감소하였다. 1년 이내 주요 심장 사고의 발생과 관련된 유의한 인자들은 여성, 고령, 고혈압, 당뇨병, 흡연, 시술 후 낮은 TIMI flow 등이었다.
