TI  - Circulatory support for patients experiencing postcardiotomy cardiogenic shock: 
      analysis of risk factors for death and long-term follow-up.
PG  - 634-9
AB  - Over the last 5 years, 12 patients received ventricular assist devices (VADs) 
      while in postcardiotomy cardiogenic shock. There were 7 male and 5 female 
      patients ranging in age from 22 to 73 years (average age, 54). Eight patients 
      underwent surgery for valve replacements, 3 for coronary artery bypass graftings, 
      and 1 for closure of a ventricular septal rupture. The duration of VAD support 
      ranged from 6 h to 9 days (mean, 4.2 days). Ten patients were weaned from the 
      VADs, and 6 survived. Univariate analysis indicated that renal failure, 
      infection, and heart failure had a negative impact on those patients who 
      survived. Multivariate analysis indicated that heart failure, renal failure, and 
      preoperative left ventricular ejection fraction were the most important 
      predictors of hospital death. The 6 survivors were followed for 4 to 42 months 
      (mean, 25 months); 5 were in New York Heart Association (NYHA) Class I, and 1 was 
      in Class II. The cardiac functions in 5 patients who lived over 1 year were 
      assessed by echocardiography. Preoperative and postoperative UCG revealed that 
      ejection fraction and mean velocity of circumferential fiber shortening increased 
      significantly (p < 0.01). Also, the left ventricular diastolic and systolic 
      dimensions decreased significantly (p < 0.05). However, the patients did not show 
      further changes in these parameters during exercise. Eight patients who had 
      double valve replacements were observed for comparison (control group). In the 
      control group, exercise improved cardiac output and mean velocity of 
      circumferential fiber shortening (p < 0.01).(ABSTRACT TRUNCATED AT 250 WORDS)
