Objective:To investigate the prognosis and related factors of ischemic cardiomyopathy.Methods:Clinical data of 271 patients with acute decompensated chronic heart failure admitted to the Cardiac Intensive Care Unit of Tianjin Chest Hospital from December 2019 to June 2022 were enrolled, including 135 cases with ischemic cardiomyopathy (ICM group) and 136 cases with non-ischemic cardiomyopathy (NICM group). Patients were followed up for 48 weeks; and the primary endpoint was all-cause death and/or readmission due to heart failure, the secondary end point was cardiogenic death. Kaplan-Meier survival curve was used to compare the difference in prognosis between the two groups. Univariate and multivariate Cox regression models were used to evaluate the factors influencing the primary and secondary end points of ischemic cardiomyopathy.Results:Compared with the NICM group, ICM group had higher proportion of patients with older age, fast pulse rate, high body mass index, comorbidities of hypertension, diabetes, chronic kidney disease, stroke or peripheral vascular disease; and greater left ventricular end-diastolic diameter, right ventricular end-diastolic anteroposterial diameter, pulmonary artery systolic blood pressure, and left ventricular ejection fraction (all P<0.05). Kaplan-Meier survival analysis showed that survival without primary endpoint (Log-rank P=0.009) and survival without secondary endpoint (Log-rank P=0.037) were lower in the ICM group than in the NICM group. Multivariate Cox regression analysis showed that elevated triglyceride (TG)/high density lipoprotein-cholesterol (HDL-C) ratio and elevated neutrophil percentage were independent risk factors for primary and secondary endpoint events in patients with ischemic cardiomyopathy. Conclusions:Patients with ischemic cardiomyopathy have lower survival rates than those with non-ischemic cardiomyopathy. High levels of TG/HDL-C ratio and neutrophil percentage are independent risk factors for poor prognosis in ischemic cardiomyopathy.

<p><b>OBJECTIVE</b>To identify the cause of an outbreak of foot pain syndrome among students from a senior high school in Foshan.</p><p><b>METHODS</b>We defined a suspect case as onset of foot pain/numbness with unknown reason among students and teachers in a school of Foshan city, from February 10 to March 16, 2014. A suspect case was noticed as having both food pain and numbness. All the cases were searched through reviewing medical records in the nearby hospitals and school's clinic, also the records of absenteeism in school. Clinical information was collected from all the students, using a standardized questionnaire. Daily temperature was collected from all the students, between January 1 and March 31, 2014. A 1 : 2 individual matched case-control study was conducted to identify related risk factors on this epidemic. We interviewed all the cases and controls on their diet, physical activities and measures used for warming.</p><p><b>RESULTS</b>A total of 407 case-students were identified, with an attack rate (AR) as 26.5%. The AR was 37.3% in girls, compared to 12.9% in boys. The difference was statistically significant (χ² = 115.1, P < 0.01). Boarding students had a higher AR (31.8%) than the commuting students (16.2%). The difference was statistically significant (χ² = 43.2, P < 0.01). In girls, boarding students had higher AR (46.1%) than those commuting students (18.5%). The difference was statistically significant (χ² = 61.4, P < 0.01). No statistically significant difference was found between boarding or commuting students in boys. Outdoor temperature was coming down from 23 °C on February 6 to 6 °C on February 13, but gradually rose to 23 °C on February 28. There was a positive relationship (r = 0.65, P = 0.002) noticed between daily maximum temperature and the number of cases during February 13-28. Results from this case-control study showed that factors as lacking physical activities (OR = 2.8, 95% CI: 1.5-5.6), feeling cold in bed (OR = 3.0, 95% CI: 1.3-7.0) and having experienced similar symptoms (OR = 3.4, 95% CI: 1.1-11.0) could increase the risk of this disease.</p><p><b>CONCLUSION</b>This outbreak was possibly caused by the abrupt fluctuation of temperature within a short period.</p>
