To evaluate nationwide trends in the utilization of Multivessel Percutaneous Coronary Intervention (MVPCI) in the past compared to recent years using a large database from 1988 to 2004.
The Nationwide Inpatient Sample (NIS) database was utilized to calculate the age-adjusted rate for multivessel percutaneous coronary intervention (MVPCI) from 1988 to 2004. Specific ICD-9-CM codes for MVPCI were used to compile the data. Patient demographic data were also analyzed from the database.
According to the NIS database, MVPCI was performed in 241,319 patients from 1988 to 2004. Males underwent MVPCI twice as many as compared to females (male: 67.87%, female 32.13%). The mean age for these patients was 64.89 +/- 11.84 years old. From 1988, the age-adjusted rate for MVPCI gradually increased to more than three times in 1998 [(6.62 per 100,000 (95%CI = 5.92-7.33) in 1988 to 23.92 per 100,000 (95%CI = 21.62-26.22, P < 0.01) in 1998] and accelerated to more than 6 times that of 1988 at the end of the study in 2004 (41.50 per 100,000 (95%CI = 37.84-45.16). In recent years, this trend was similar for both genders and ethnicities.
The utilization of MVPCI has increased six times from 1988 to 2004, with acceleration in recent years. The cause of this acceleration is most likely related to the advancement in the percutaneous coronary interventional techniques.
利用 1988 年至 2004 年的大型数据库，评估过去和近年来多血管经皮冠状动脉介入治疗（MVPCI）的全国性趋势。
利用全国住院患者样本（NIS）数据库计算 1988 年至 2004 年多血管经皮冠状动脉介入治疗（MVPCI）的年龄调整率。使用 MVPCI 的特定 ICD-9-CM 代码来编译数据。还从数据库中分析了患者的人口统计学数据。
根据 NIS 数据库，1988 年至 2004 年共有 241319 例患者接受 MVPCI。男性接受 MVPCI 的次数是女性的两倍（男性：67.87%，女性：32.13%）。这些患者的平均年龄为 64.89±11.84 岁。从 1988 年开始，MVPCI 的年龄调整率逐渐增加，到 1998 年增加了三倍以上[（1988 年每 10 万人 6.62 例（95%CI=5.92-7.33），1998 年每 10 万人 23.92 例（95%CI=21.62-26.22，P<0.01）]，并在研究结束时加速到 2004 年的 1988 年的 6 倍以上（每 10 万人 41.50 例（95%CI=37.84-45.16）。近年来，这种趋势在两性和种族中都很相似。
1988 年至 2004 年，MVPCI 的使用率增加了六倍，近年来呈加速趋势。这种加速的原因很可能与经皮冠状动脉介入技术的进步有关。
