In the present study, we aimed to investigate whether copeptin values on admission are related to left ventricle (LV) systolic function and its improvement at 6 months in ST-segment elevation myocardial infarction (STEMI) patients. In this single-center, prospective observational study, we included 122 STEMI patients from January 2016 to November 2016. LV systolic functions in the form of global longitudinal strain (GLS) in addition to conventional echocardiography parameters were evaluated on admission and at 6-month. Serum copeptin levels were determined using an ultrasensitive immunofluorescence assay. The study population was divided into 2 groups according to median values of copeptin. GLS was significantly lower in patients with high copeptin levels compared to those with low copeptin levels at early stage and 6-month (−16% (16–16.5) vs −15% (15–15.5), P

The clinical significance of poor nutritional status in patients with peripartum cardiomyopathy (PPCM) is not clearly understood. Prognostic nutritional index (PNI) is a simple nutritional assessment tool, which was first demonstrated to be valuable in patients with colorectal surgeries. We aimed to investigate the predictive value of PNI in patients with PPCM. A total of 92 patients diagnosed with PPCM were enrolled in this study. PNI was calculated using the following formula: 10 × serum albumin value (g/dL) + 0.005 × total lymphocyte count. The primary endpoint was defined as composite adverse cardiac events that included cardiac death or hospitalization due to worsening heart failure (HF). Cardiac death, hospitalization due to worsening HF, and persistent left ventricular (LV) systolic dysfunction were evaluated, respectively, as secondary endpoints. Primary composite endpoint was higher in the lower PNI group. After adjusting for other risk factors, PNI was found to be as an independent predictor of primary composite endpoint (odds ratio 0.805; 95% confidence interval 0.729–0.888; P
