Summary
Cardiac rupture (CR) occurred in 12% of acute myocardial infarction (AMI) deaths. Previous myocardial infarction may reduce CR risk, while cardiokinetic therapy might increase it, especially with high doses.
Area of Science:
- Cardiology
- Pathology
Context:
- Cardiac rupture (CR) is a severe complication of acute myocardial infarction (AMI).
- Understanding CR's incidence and risk factors is crucial for patient outcomes.
Purpose:
- To investigate the incidence and predisposing factors of cardiac rupture in patients deceased from acute myocardial infarction.
- To analyze the temporal relationship between AMI onset and CR, and identify potential premonitory signs.
Summary:
- Cardiac rupture (CR) was observed in 12% of 200 necropsies for acute myocardial infarction (AMI).
- Factors like age, sex, AMI site, hypertension, diabetes, and anticoagulant/corticosteroid use were insignificant.
- Previous myocardial infarction appeared to reduce CR incidence, which predominantly occurred within the first 3-4 days post-AMI and never after 21 days.
- Persistent precordial pain without pericardial friction was a key premonitory sign.
- The increased frequency of CR may be linked to the prevalent use of high-dose cardiokinetic therapy during AMI.
Impact:
- Findings suggest cautious use of cardiokinetic therapy in high-risk AMI patients, favoring smaller doses after other treatments.
- Recommendations include considering emergency surgery or preventive infarctectomy for high-risk individuals.
- Highlights the importance of monitoring for precordial pain as a warning sign of impending CR.
