Transthoracic echocardiography (including colour tissue Doppler imaging-derived myocardial velocities, strain and strain rates), troponin-T and B-type natriuretic peptide (BNP) and clinical details were recorded at baseline, after conditioning chemotherapy and serially over 6 weeks from the day of transplantation.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Results:<\/jats:title>\n                  <jats:p>The mean (SD) LVEF at baseline was 62 (6)% and decreased to 55 (16)%, 6 weeks after transplantation (p\u200a=\u200a0.007). Cardiac toxicity (\u2a7e10% absolute decline of LVEF to an LVEF \u2a7d50%) developed in 10 (31%) patients within 17 (8) days of transplantation and was usually reversible. In these 10 patients, the nadir LVEF was 39 (12)%. Two patients developed severe clinical pulmonary oedema, one episode of which was fatal. Troponin-T was mildly raised in only three of the patients with cardiac toxicity. Peak BNP values were similar in patients with or without post-transplant cardiac toxicity (149 (100) vs 196 (178) pg\/ml, p\u200a=\u200a0.43). Multivariate Cox proportional hazard regression identified baseline mitral annular systolic velocity as the only independent predictor of cardiac toxicity (hazard ratio 0.42, 95% confidence interval 0.20 to 0.86, p\u200a=\u200a0.02).<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusion:<\/jats:title>\n                  <jats:p>Subacute cardiac toxicity is common after autologous haematopoietic stem cell transplantation, even in patients with apparently normal left ventricular function.
