The influence of left bundle branch block on the outcome of acute myocardial infarction

Left bundle brunch block (LBBB) worsens the prognosis of patients with acute myocardial infarction (AMI). A new LBBB is a sign of extensive myocardial necrosis, while the preexistent one refers to myocardial damage that occurred before the onset of AMI. However, in many cases at hospital admittance there are no data on the possible previous existence of LBBB. Our study included 1341 patients with AMI. There were 1183 of them without BBB, LBBB was registered in 71 patients and the remaining number had a right bundle brunch block. Patients with LBBB were older (70&plusmn ; 9 vs. 62&plusmn ; 11 years, p<0.001 ), more often had previous angina (69% vs. 47%, p<0.001) and previous myocardial infarction (34% vs. 20%, p=0.005). In the group without BBB there were more often men (71% vs. 59%, p=0.03), obese patients (31% vs. 14%, p=0.002) and smokers (48% vs 22%, p<0.001). Patients with LBBB were divided in tree subgroups: with new LBBB, preexistent LBBB and LBBB of unknown age. Total mortality was 11%. In the group without BBB 100 patients died and in the group with LBBB 26 patients (8% vs. 37%, p<0.001). No significant difference in mortality existed between the group with preexistent LBBB and the group without BBB, mortality was significantly higher in the sub group with new LBBB (59% vs. 8%, p<0.001) and in the subgroup with LBBB of unknown age (40% vs. 8%, p<0.001). In conclusion, patients with AMI and new LBBB have significantly higher mortality than patients without BBB. Similar higher mortality exists in patients with LBBB of unknown age, while in patients with preexistent LBBB it is similar to those in patients without LBBB. It is therefore likely that among patients with AMI and LBBB of unknown age, those with new LBBB dominate.
