Identification of risk factors of 30-day readmission and 180-day in-hospital mortality, and its corresponding relative importance in patients with Ischemic heart disease: a machine learning approach

Background: Ischemic heart disease (IHD) is one of the leading causes of mortality in Pakistan. With advancement in research, multiple causes have contributed in development of web of causation of this public health issue. The objective of this study was to assess gender differences in risk factors associated with ischemic heart disease in patients presenting at the biggest cardiology hospital of Lahore. Patients and methods: A comparative cross-sectional study was carried out in Punjab Institute of Cardiology, Lahore from January to August, 2018 on a sample of 296 diagnosed patients of IHD, through non-probability consecutive sampling technique. Data was collected on pretested questionnaire. The data was analyzed using SPSS version 22. Chi-Square test of significance was applied and a p-value ≤0.05 was considered statistically significant. Results: The mean age of participants was 45±12 years with predominance of male patients (71.3%). Frequency of risk factors for IHD included increase body mass index (83.8%), hypertension (61%), insufficient physical activity (43%), diabetes (38.5%) and smoking (23%). Increase serum cholesterol was reported in 95% and triglycerides in 99% of the participants. Gender difference was significant with females residing in urban population (p=0.054) and exercise routine (p=0.034). Males showed high tendency of IHD with smoking pattern (p<0.001) contrary to presence of diabetes in females (p=0.05), hypertension (p=0.054), BMI (p=0.0379) and stressful event in life (p=0.002). Males showed regular intake of medicines (p =0.045) after diagnosis as compared to female population. Conclusion: There is more frequency of ischemic heart disease in males as compared to females. Significant association was observed with residence in urban area, presence of diabetes, hypertension, high BMI and stressful event in life in occurrence of ischemic heart disease in female population.

Left bundle branch block is not a benign pathology, and its presence requires the identification of a pathological substrate, such as ischemic heart disease. Left bundle branch block appears to be more commonly associated with normal coronary arteries, especially in women. The objectives of our study were to describe the particularities of left bundle branch block in women compared to men with ischemic heart disease. Result: We included seventy patients with left bundle branch block and ischemic heart disease, with a mean age of 67.01 ± 8.89 years. There were no differences in the profile of risk factors, except for smoking and uric acid. The ventricular depolarization (QRS) duration was longer in men than women (136.86 ± 8.32 vs. 132.57 ± 9.19 msec; p = 0.018) and also men were observed to have larger left ventricular diameters. Left bundle branch block duration was directly associated with ventricular diameters and indirectly associated with left ventricular ejection fraction value, especially in women (R = −0.52, p = 0.0012 vs. R = −0.50, p = 0.002). In angiography, 80% of women had normal epicardial arteries compared with 65.7% of men; all these patients presented with microvascular dysfunction. Conclusion: The differences between the sexes were not so obvious in terms of the presence of risk factors; instead, there were differences in electrocardiographic, echocardiographic, and angiographic aspects. Left bundle branch block appears to be a marker of microvascular angina and systolic dysfunction, especially in women.

Abstract Background In clinical setting, ischemic heart disease is a challenging problem in hemodialysis (HD) population. Coronary flow reserve (CFR) measured by 13 ammonia positron emitting tomography (13NH3PET) is an established and reliable modality for detecting coronary artery disease. Furthermore, some prior studies show CFR is an important and independent predictor for cardiovascular event and mortality. On the other hand, HD patients with malnutrition status have poor prognosis. We have reported about the relationship between cardiovascular events and geriatric nutrition risk index (GNRI). Now, we wonder the predictability of combination of CFR and GNRI. Methods and result We collected 438 consecutive HD patients who received 13NH3PET in our hospital suspected for ischemic heart disease. 29 patients were excluded due to undergoing coronary revascularization within 60 days, 103 patients were excluded due to incomplete database. In total, 306 HD patients were classified into 4 group according the median value of CFR (1.99) and GNRI (97.73); Low CFR Low GNRI group (n=77), High CFR and Low GNRI group (n=76), Low CFR High GNRI group (n=78) and High CFR High GNRI group (n=75). We collected their follow up data up to 1544 days (median 833 days) about all-cause mortality and cardiovascular (CV) mortality. Surprisingly, there is no mortality event in High CFR High GNRI group. We analyzed about all-cause mortality, CV mortality. Kaplan-Meyer analysis shows there are statistically intergroup differences in each (all-cause mortality; log rank p<0.01, CV mortality; log rank p=0.02). Furthermore, we calculated area under the curve (AUC) analysis, net reclassification improvement (NRI) and integrated discrimination improvement (IDI)m adding GNRI and CFR on conventional risk factors. There are intergroup differences for all-cause mortality in AUC [conventional risk factors, +GNRI, +GNRI+CFR; 0.70, 0.72 (p=0.29), 0.79 (p<0.01)], NRI [+GNRI; 0.32 (p=0.04), +GNRI+CFR 0.82 (p<0.01)] and IDI [+GNRI; 0.01 (p=0.05), +GNRI+CFR 0.09 (p<0.01)]. Conclusion HD patients with low CFR and malnutrition status has statistically significant poorer prognosis comparing HD patients with high CFR and without malnutrition status. Adding combination of GNRI and CFR on conventional risk factors improves the predictability of HD population's prognosis. Funding Acknowledgement Type of funding source: None

Abstract Background: Previous studies suggested that plasma B-type natriuretic peptide (BNP) level was often elevated in patients with acute exacerbations of chronic obstructive pulmonary disease (AECOPD) and was associated with increased mortality. However, most studies did not consider the fact that conditions such as coronary ischemic heart disease can also increase BNP level. Therefore, we aimed to explore the association between BNP level and in-hospital mortality in patients with AECOPD without a history of coronary ischemic heart disease.Methods: In this retrospective cohort study, patients who were diagnosed with AECOPD using International Statistical Classification of Diseases and Related Health Problems, Nineth Revision (ICD-9 codes) between January 2017 and December 2019. All data were obtained from electronic patient files and medical data intelligence platform of Jinan Central Hospital. BNP level was determined within 24 hours after admission, and the value was log2 transformed. The primary outcome was in-hospital mortality, and the secondary outcome was a composite outcome of in-hospital mortality or invasive mechanical ventilation.Results: A total of 300 patients were included in this study. Univariate cox regression analysis showed that the unadjusted HRs of the primary and secondary outcomes were 1.85 (95% CI, 1.39-2.47) and 1.45 (95% CI, 1.20-1.75), respectively. After adjustment for age, sex, past medical history, smoking status, drinking status, CURB65 (Confusion, Urea > 7mmol/L, Respiratory rate≥30/min, Blood pressure systolic < 90 mmHg or diastolic <60 mmHg and age > 65 years), arterial partial pressure of O2(PaO2), the adjusted HRs of the primary and secondary outcomes were 3.65 (95% CI, 2.54-5.26) and 1.43 (95% CI, 1.14-1.97), respectively. The results of subgroup analysis by age, sex, and lung function were robust. This study was retrospective, so there was no clinical trial registration.Conclusions: The plasma log2BNP level was significantly associated with in-hospital mortality and a composite outcome of in-hospital mortality or invasive mechanical ventilation.
