Our study showed that EF improved from 24 hours after placing the balloon and increased significantly after 72 hours (EF% from 26.5 ± 13.5% to 34.6 ± 14.1%, p <0.05), cardiac output index (CI) improved after placing the ball 48 hours: 2.05 ± 0.5 to 3.9 ± 0.8 / minute / m2; The survival group improved better than the mortality group after 24 hours of placing the ball: 32.1 ± 12.2% compared with 28.2 ± 12.6% (p <0.05), CI increased after 24 hours: 4.0 ± 1.5 compared with 2.2 ± 0.5 l / min / m2 (p <0.05).
