Key result
Prophylactic permanent pacing did not prevent death in patients surviving transient complete AV block with acute anterior MI, with 8 of 9 paced patients dying within two years (7 suddenly).
Why the study?
Does prophylactic permanent pacing reduce the incidence of late sudden death in patients surviving transient complete atrioventricular block with acute anterior myocardial infarction?
RCT (n=14)
Does prophylactic permanent pacing reduce the incidence of late sudden death in patients surviving transient complete atrioventricular block with acute anterior myocardial infarction?
Prophylactic permanent pacing does not prevent late sudden death and is not warranted in patients surviving transient complete AV block complicating acute anterior myocardial infarction.
Prophylactic permanent pacing is not warranted after transient complete AV block in anterior MI; challenges routine use and supports expectant management.
A randomised study was performed to assess the influence of prophylactic permanent pacing on the incidence of late sudden death in patients surviving transient complete atrioventricular block with acute anterior myocardial infarction. Fourteen patients were studied, of whom ten died within two years, confirming the high overall late mortality in this group. The deaths included eight of the nine paced patients, of whom seven died suddenly. We conclude that prophylactic permanent pacing is not warranted in patients surviving transient complete atrioventricular block with acute anterior myocardial infarction.

Grigg et al. (1988) conducted an RCT in transient complete atrioventricular block with acute anterior myocardial infarction (n=14). Prophylactic permanent pacing vs. No pacing was evaluated on incidence of late sudden death. Prophylactic permanent pacing did not prevent death in patients surviving transient complete AV block with acute anterior MI, with 8 of 9 paced patients dying within two years (7 suddenly).
