Insights
Psychoses following heart surgery, including commissurotomy and valve replacement, are linked to a hypercoagulable state. This condition involves disseminated intravascular coagulation (DIC) of the blood.
Area of Science:
- Neurology
- Cardiology
- Hematology
Context:
- Psychotic episodes can occur post-cardiac surgery.
- Incidence rates vary: 1.24% after closed commissurotomy, 3.22% after open commissurotomy, and 9.1% after heart valve prosthetics.
- The underlying mechanism of post-surgical psychosis requires elucidation.
Purpose:
- To investigate the etiological factors of psychosis following specific cardiac surgical procedures.
- To identify a common pathophysiological link between different types of heart surgery and subsequent psychosis.
Summary:
- A study examined 56 patients experiencing psychosis after closed commissurotomy, open commissurotomy, or heart valve prosthetics.
- Findings indicate that the hypercoagulative phase of disseminated intravascular coagulation (DIC) is the primary cause of these psychoses.
- This suggests a hematological basis for neurological complications in cardiac surgery patients.
Impact:
- Highlights the importance of monitoring coagulation status in patients undergoing cardiac surgery.
- May inform prophylactic strategies to prevent psychosis in at-risk surgical populations.
- Emphasizes the link between cardiovascular procedures, coagulation disorders, and neuropsychiatric outcomes.
Abstract:
The examination of 56 patients with psychoses following closed commissurotomy (in 1,24% of cases), open commissurotomy (in 3,22%) and prosthetics of heart valves (in 9,1%) enabled the authors to conclude that they are caused by hypercoagulative phase of the disseminated intravascular coagulation of blood.
