Summary
Surgical reduction of left ventricular aneurysms demonstrated a 5-year survival of 79% and 10-year survival of 67%. Early mortality risks were linked to patient condition and perioperative factors, but not long-term survival.
Area of Science:
- Cardiology
- Cardiac Surgery
- Medical Outcomes Research
Background:
- Left ventricular aneurysms are serious complications following myocardial infarction.
- Surgical intervention aims to improve survival and cardiac function.
- Long-term outcomes and predictors of mortality require further investigation.
Purpose of the Study:
- To retrospectively evaluate the surgical results of left ventricular aneurysm reduction.
- To identify factors influencing early and late mortality after surgery.
- To assess the long-term efficacy of surgical therapy.
Main Methods:
- Retrospective review of 197 consecutive patients undergoing left ventricular aneurysm reduction between 1977 and 1987.
- Analysis of preoperative, perioperative, and postoperative variables.
- Follow-up study of late survivors to assess long-term outcomes.
Main Results:
- Hospital mortality was 9.6% (19 patients); late mortality resulted in 38 deaths.
- Cumulative 5- and 10-year survival probabilities were 79% and 67%, respectively.
- Increased early mortality risk was associated with advanced New York Heart Association class, recent myocardial infarction, ventricular arrhythmia, congestive heart failure, renal failure, and cardiogenic shock.
Conclusions:
- Surgical left ventricular aneurysm reduction offers significant long-term survival benefits.
- Patient's preoperative status and perioperative complications are critical determinants of early survival.
- No specific preoperative or perioperative variable reliably predicted late mortality or survival duration.
