[The value of enzyme-determination after cardiac surgery (author's transl)]
Insights
Serum enzyme levels (GOT, GPT, LDH, alpha-HBDH, LAP, CK, CK-MB) were monitored in 342 open heart surgery patients. Enzyme elevations correlated with surgery type, bypass duration, and postoperative outcomes, indicating specific organ stress.
Area of Science:
- Biochemistry
- Cardiology
- Surgical Monitoring
Context:
- Open heart surgery involves significant physiological stress.
- Monitoring biochemical markers is crucial for assessing patient recovery.
- Serum enzyme levels can indicate organ damage or dysfunction post-surgery.
Purpose:
- To determine serum enzyme level changes in patients undergoing open heart surgery.
- To correlate enzyme elevations with surgical factors and postoperative complications.
- To establish patterns of enzyme changes for uncomplicated cases.
Summary:
- Serum enzyme levels (GOT, GPT, LDH, alpha-HBDH, LAP, CK, CK-MB) were measured in 342 patients from operation start to day 14 post-op.
- Enzyme elevations varied based on operation type, extracorporeal circulation duration, and patient recovery.
- A distinct pattern of enzyme changes was identified for uncomplicated cases.
- Significant correlations were found between liver-specific enzymes and right heart failure, and heart-specific enzymes and myocardial ischemia.
Impact:
- Provides a reference for interpreting serum enzyme changes after open heart surgery.
- Highlights the diagnostic value of serial enzyme measurements in surgical patients.
- Supports the use of specific enzyme profiles to identify postoperative complications like right heart failure and myocardial ischemia.
Abstract:
In 342 patients undergoing open heart surgery we determined the serum enzyme levels of GOT, GPT, LDH, alpha-HBDH, LAP, CK and CK-MB from the beginning of the operation up to the 14 th postoperative day. There was an elevation of serum enzymes depending on the type of operation, the duration of extracorporal circulation and the postoperative course. A pattern of enzyme changes for uncomplicated cases is described. The investigations demonstrate a statistically significant correlation between the elevation of "liver specific enzymes" and right heart failure on one hand and of "heart specific enzymes" and myocardial ischemia on the other hand. It is concluded that only repeated determinations beginning with the operation enable to evaluate serum enzyme levels.
