OBJECTIVE: Left ventricular free wall rupture (LVFWR) is a rare but severe complication of acute myocardial infarction (AMI). During the era of pre-thrombolysis, autopsies revealed an incidence of approximately 8%.
METHOD: The objective of this retrospective study was to analyze the current incidence of LVFWR and to identify predictors by comparing the AMI-cohort with LVFWR to those without. The control group involved a random selection of one in every ten patients who presented with acute myocardial infarction between 2005 and 2014.
RESULT: A total of 5143 patients with AMI were treated at the Central Hospital, Bad Berka (71% men, median age 68 years). Out of these, seven patients with LVFWR were identified with an overall incidence of 0.14%. Clinically, LVFWR patients presented late to admission since symptom onset (median 24 h vs. 6.1 h; p < 0.0001), were more likely in cardiogenic shock (28.6% vs. 3.2%; p = 0.02) and were usually accompanied by emergency physicians (71.4% vs. 20.7%; p = 0.006). Higher troponin T (median 8.6 vs. 0.5 ng/ml; p < 0.0002), higher CRP (median 50 vs. 0.5 mg/l; p = 0.05) as well as a lower hematocrit-values (0.33 vs. 0.42; p = 0.04) were observed. All LVFWR patients were operated (100% vs. 1.6%; p < 0.001). The patients had lower rates of beta-blocker treatment (57.1% vs. 95.8%; p = 0.003). The 30-day mortality was significantly higher (42.9% vs. 6.8%; p = 0.01).
CONCLUSION: Compared to the thrombolytic era, the current incidence of LVFWR with AMI, who reach the hospital alive, is significantly lower. However, 30-day mortality continues to be high.
