Clinical impact of perioperative myocardial infarction after pancreatic surgery.

BACKGROUND

The aim of this study was to evaluate the incidence, clinical impact and outcome of perioperative myocardial infarction (PMI) in patients undergoing pancreatic surgery.

METHODS

A data of 1,625 patients undergoing pancreatic resection were prospectively collected and analysed with regard to PMI. Demographic aspects, co-morbidities and clinical course were evaluated. Cardiac risk factors (ASA and NYHA), postoperative complications and mortality were compared in a match-pair analysis (1:3) with patients without PMI.

RESULTS

Twenty-nine patients with PMI after pancreatic surgery were identified. PMI occurred after all types of pancreatic operations and was observed most frequently (72.2%) within the first postoperative week. In a total of 90%, PMI fulfilled the criteria of non-STEMI. Nearly half of the patients (48%) were clinically asymptomatic. Both ASA III and heart failure were more frequent in patients with PMI. The in-hospital mortality was significantly increased after PMI (p < 0.002), with post-pancreatectomy haemorrhage (PPH) as the most relevant underlying risk factor.

CONCLUSION

PMI is a rare but severe complication after pancreatic operations, contributing significantly to in-hospital mortality. Clinical management mainly includes an anti-coagulant approach. This may be related with an increased risk for PPH. Therefore, the use of anti-coagulant drugs in the early postoperative period-especially in asymptomatic patients-should be critically evaluated.
