Introduction: Systemic Lupus Erythematosus (SLE) is a chronic inflammatory disease of autoimmune origin that affects multiple systems, with the haematologic system being commonly involved. However, the co-existence of haemoglobinopathies and connective tissue disorders has rarely been investigated, and the available data on this matter are primarily anecdotal. Aim: To determine the prevalence of Haemoglobin E (HbE) haemoglobinopathy in adult SLE patients and to assess the association of HbE haemoglobinopathy and SLE with disease activity. Materials and Methods: A hospital-based cross-sectional study was conducted at the Department of General Medicine, Regional Institute of Medical Sciences (RIMS) Hospital, Imphal, Manipur, India, from April 2021 to July 2022. The study included SLE patients diagnosed during the study period who attended the rheumatology Outpatient Department (OPD). The independent variables were age, gender, occupation, religion, and family history, while HbE haemoglobinopathy, Mean Corpuscular Volume (MCV), Mean Corpuscular Haemoglobin (MCH), Red Blood Cell (RBC) count, and Systemic Lupus Activity Measure Revised Index (SLAM-R index) score were the dependent variables. Data were analysed using Statistical Package for Social Sciences (SPSS) version 21.0, with proportions analysed using the Chi-square test and Fisher's-exact test, and means compared using Analysis of Variance (ANOVA) and independent t-test. A p-value of <0.05 was considered significant. Results: Of the 105 SLE patients included in the study, 93% were females. The majority of participants (36.2%) were in the age group of 21-30 years. Twenty-five patients (23.8%) had HbE haemoglobinopathy. Anaemia and MCV were significantly associated with HbE patients. Among the 25 HbE patients, 24 (96%) had active SLE disease. Among the HbE negative patients, 55 (68.7%) had active disease, while 25 (31.3%) did not have any active disease. Active SLE disease was significantly associated with HbE haemoglobinopathy (p-value=0.002). Conclusion: The overall prevalence of HbE haemoglobinopathy in SLE patients was found to be 24%. Hb levels and MCV levels were significantly lower in HbE patients. There was a significant association between active SLE disease and HbE haemoglobinopathy. [ABSTRACT FROM AUTHOR]

Ranolazine is an anti-anginal medication given to patients with chronic angina and persistent symptoms despite medical therapy. We examined 11 491 chronic total occlusion (CTO) percutaneous coronary interventions (PCI) that were performed at 41 US and non-US centers between 2012 and 2023 in the PROGRESS-CTO Registry. Patients on ranolazine at baseline had more comorbidities, more complex lesions, lower procedural and technical success (based on univariable but not multivariable analysis), and higher incidence of major adverse cardiac events (MACE) (on both univariable and multivariable analysis).

Background: Assessment of health-related quality of life (HRQoL) is an important measure of a patient's recovery after an illness. However, HRQoL among acute coronary syndrome (ACS) survivors has not been extensively studied following cardiac management., Aim: The purpose of this study was to assess the quality of life (QoL) among ACS patients who have undergone percutaneous coronary intervention (PCI)., Methods: This cohort study included 145 consecutive male ACS patients between March 2021 and May 2022. Of these patients, 138 (mean age 54.3 ± 10.7 years) completed the QoL assessment using the short form-12 (SF-12) health survey questionnaire. Seventy (51%) of them presented with ST-segment elevation myocardial infarction (STEMI), 18 (13%) had non-STEMI, 39 (28%) had evolved MI, and 11 (8%) had unstable angina. Recruited patients' QoL data were assessed at various time points post-PCI., Results: At the end of the 12 months of follow-up, major clinical events (MCE) defined as death, sudden death, or re-acute myocardial infarction occurred in 54.9% of patients. Out of 7 MCE, four deaths and three re-AMIs had occurred. SF-12 physical component score was found to be significantly improved when compared to the mental component score, which seems to improve without reaching statistical significance over time. Among event-free ACS patients, we found a significant positive correlation between left ventricular ejection fraction and HRQoL., Conclusion: Improvement in HRQoL (physical component) was seen among ACS patients post-PCI., Relevance for Patients: QoL assessment outcomes should be considered in clinical settings, practice guidelines, and treatment modality post-PCI to improve QoL in post-ACS survivors., Competing Interests: The authors claim to have no conflicts of interest., (Copyright: © 2023 Author(s).)
