Overall, 216 patients (83%) had undergone EMB, 47 with repeat procedures. EMB overall sensitivity was 38%, rising to 49% after repeat biopsies. On logistic regression analysis, positive EMB was predicted independently by presentation with ventricular tachyarrhythmia with an odds ratio (OR) of 3.8 (95% confidence interval [CI] 1.2\u201312.0, p\u2009=\u20090.021), left ventricular ejection fraction \u226445% (OR 3.7, 95% CI 1.5\u20139.1, p\u2009=\u20090.004), elevation of cardiac troponins (OR 2.7, 95% CI 1.1\u20136.4, p\u2009=\u20090.024), and presence of late gadolinium enhancement in left ventricular mid-apical septal segments on magnetic resonance imaging (OR 4.1, 95% CI 1.2\u201313.8, p\u2009=\u20090.024). EMB sensitivity, counting in repeats, was 16% in patients (n\u2009=\u200937) without any independent predictor versus 38%, 60%, 79%, and 88% in those with 1 (n\u2009=\u200976), 2 (n\u2009=\u200962), 3 (n\u2009=\u200933), and 4\/4 (n\u2009=\u20098) predictors, respectively. The rate of serious complications was 0.7% without mortality or permanent harm.
