Of these, 60 (3.3%) patients with severe thinness, 213 (11.8%) with mild\u2013moderate thinness and 1161 (64.4%) with normal weight were assessed for in-hospital and mid-term outcomes.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>RESULTS<\/jats:title>\n                  <jats:p>While there were no differences in age, male sex, malignancy or ejection fraction among the groups, the severe thinness group exhibited lower albumin and haemoglobin levels. The severe thinness group had higher in-hospital mortality (6.7% vs 0.0% vs 0.7%, P\u2009= \u20090.001). Median follow-up period was 4.3 [3.8\u20135.0] years. Cumulative all-cause mortality at 5 years was significantly higher in the severe thinness than in the mild\u2013moderate thinness and normal-weight groups (77.9% vs 61.6% vs 44.4%, P\u2009&amp;lt; \u20090.001). The severe thinness group had a higher cumulative incidence of not only cardiac mortality (50.2% vs 35.0% vs 26.5%, P\u2009= \u20090.002) but also non-cardiac mortality (55.7% vs 40.9% vs 28.6%, P\u2009&amp;lt; \u20090.001). Multivariable analysis demonstrated that severe thinness (adjusted hazard ratio [aHR], 3.00; 95%confidence interval [CI], 2.03\u20134.41, P\u2009&amp;lt; \u20090.001) and mild\u2013moderate thinness (aHR, 1.35; 95% CI, 1.03\u20131.76, P\u2009= \u20090.027) were independent risk factors for the mid-term mortality.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>CONCLUSIONS<\/jats:title>\n                  <jats:p>Severe thinness increases the risk of in-hospital mortality.
