PG - 1454-61 LID - 10.1111/ijcp.12481 [doi] AB - AIMS: Low testosterone (T) level is associated with cardiovascular risk factors. However, the relationship between T level and heart function in asymptomatic men with type 2 diabetes mellitus (T2DM) is unknown. METHODS: A total of 325 men were recruited who had no history, symptoms, or signs of heart disease. RESULTS: T2DM had significantly lower free T (FT) levels than those with normal glucose metabolism (NGM) (428 +/- 38 pmol/l vs. 444 +/- 38 pmol/l, p = 0.0002), and had an increased risk of LVDD (66.1% vs. 31.8%). There was a significant difference in FT level between subjects with and without LVDD among those with T2DM (421 +/- 37 pmol/l vs. 442 +/- 40 pmol/l, p = 0.0007), but not among those with NGM (439 +/- 37 pmol/l vs. 447 +/- 39 pmol/l, p = 0.247) or in the group overall (426 +/- 38 pmol/l vs. 445 +/- 38 pmol/l, p = 0.156). Lower FT level was significantly associated with LVDD [univariate odds ratio (OR) = 0.63, p = 0.032; multivariate OR = 0.71, p = 0.039]. Receiver operating characteristic curve analysis of the usefulness of FT level for predicting LVDD showed an area under the curve (AUC) of 0.85 for T2DM (p < 0.001) and 0.66 for NGM (p < 0.05). FT level had a high predictive value for LVDD in T2DM (83% for FT < 414 pmol/l), but a low predictive value in NGM (61% for FT < 423 pmol/l). Comparison of the AUCs showed that FT level was more strongly correlated with LVDD in T2DM than in NGM. CONCLUSIONS: Lower FT level is correlated with LVDD in asymptomatic middle-aged men with T2DM.
