OBJECTIVES: The aim of the present study was to study the outcome of coronary stenting in patients with symptomatic myocardial bridging refractory to standard medical therapy.
BACKGROUND: Medical therapy constitutes the first line treatment for patients with symptomatic myocardial bridge, surgical correction may be offered to select patients with refractory symptoms. Limited data exists on the outcome of coronary stenting in this patient cohort.
METHODS: Twenty-nine patients with symptoms of angina, documented myocardial ischemia and angiographically documented myocardial bridge of the left anterior descending artery (defined as [mt]50% systolic compression) were identified retrospectively. Seventeen (59%) patients responded to maximized medical therapy (mean age 51 +/- 16 years, range 29-80, 7 female) and 12 (41%) patients received coronary stents following a failed attempt of minimum 3 months of maximal medical therapy (mean age 49 +/- 15 years, range 32-76 years, 5 females). Medical therapy responders were compared with intracoronary stent group for recurrent severe angina, target vessel revascularization (TVR), myocardial infarction (MI), and death at follow-up.
RESULTS: Intracoronary stents were placed in all patients successfully. The incidence of recurrent severe angina and TVR were significantly greater in the stent group (P = 0.04) while MI and death in two groups were similar at mean follow-up of 15 +/- 3 months.
CONCLUSIONS: Coronary stent placement for medically refractory symptomatic myocardial bridge failed to relieve severe angina and is associated with high clinical restenosis and hence should be avoided.
