Limited data exist regarding the real-world practices and clinical outcomes in patients with ischemic heart failure with reduced left ventricular ejection fractions (LVEFs).Using nationwide registry data from South Korea, we aimed to investigate long-term outcomes and clinical practices, especially implantable cardioverter defibrillators (ICDs) implantation, in patients with reduced LVEFs at least 40 days after acute myocardial infarction (AMI). Of 13,056 patients with AMI between 2011 and 2015, we analyzed 350 (median age, 66 years [interquartile range, 56-75]) who had LVEFs <40% on follow-up transthoracic echocardiogram 40 days after the index event. The primary outcome was cardiac-cause mortality at 3 years. Secondary outcomes comprised major cardiovascular events as well as outcomes defined by the use of ICDs, cardiac resynchronization therapy defibrillators (CRT-Ds), and electrophysiology studies. Among 350 patients, 39 (11.1%) died from cardiac causes during 3 years of follow-up. Eleven (3.1%) were hospitalized for ventricular tachycardia. The rate of ICD or CRT-D implantation up to 3 years was 5.7% (20/350). Cox time-to-event analysis revealed older age, LVEF <30%, diabetes mellitus, and previous MI or revascularization as positively associated with cardiac death, whereas the use of statins and body weight <67 kg were negatively associated. This nationwide Korean registry demonstrated that only 5.7% of patients who had reduced LVEFs after 40 days of AMI underwent ICD implantations over 3 years. Considering the high mortality, concerted efforts are needed to improve clinical outcomes for patients who may have been candidates for ICD implantation.

This study aimed to assess the utilization trends of pulmonary rehabilitation (PR) among lung cancer patients in Korea using the National Health Insurance Service (NHIS) database (2017 to 2021). PR was introduced and covered under the NHIS in 2016, primarily for chronic obstructive pulmonary disease, but recent evidence suggests its benefits for lung cancer patients. Data extraction was based on Korea Informative Classification of Diseases 8th revision codes C33 and C34, with PR prescriptions identified by codes MM440 and MM290.Descriptive statistical analysis was performed, and propensity score matching was used for comparison between PR and non-PR groups. Results showed a significant increase in PR utilization, with the number of patients receiving PR (MM440) rising from 1,002 in 2017 to 3,723 in 2021, indicating a 3.7-fold increase. However, the proportion of patients receiving PR remained low at 2.9% in 2021. Enhanced access to PR services and improved evaluation strategies are essential for optimizing patient outcomes.

Purpose: To evaluate the potential of incorporating respiratory muscle strength, specifically maximal inspiratory pressure (MIP), and maximal expiratory pressure (MEP), along with traditional sarcopenia screening measures such as hand grip strength (HGS) and skeletal muscle mass index (SMI), to identify sarcopenia in older men. Materials and Methods: A retrospective analysis was conducted involving male patients aged 65 years and older who underwent measurements of respiratory muscle strength, HGS, and muscle mass at a general hospital in Korea from July 2016 to May 2022. Statistical analysis utilized independent t-tests and receiver operating characteristic (ROC) curves to assess the sensitivity and specificity of MIP, MEP, HGS, and SMI in sarcopenia screening. The cut-off values for sarcopenia screening were determined based on the area under the ROC curve (AUC). Results: The analysis of 282 study participants revealed the following cut-off values for sarcopenia based on the AUC: for MIP, the cut-off value was 65.50 cmH2O (AUC=0.70, sensitivity: 0.63, specificity: 0.61), while for MEP, it was 84.50 cmH2O (AUC=0.74, sensitivity: 0.66, specificity: 0.68). Conclusions This study showed the utility of respiratory muscle strength in screening for sarcopenia among older men. We suggest the screening cut-off values as 65.50 cmH2O for MIP and 84.50 cmH2O for MEP. Even when HGS and SMI measurements are not feasible, sarcopenia can be reasonably predicted based on respiratory muscle strength.

Many countries have published clinical practice guidelines for appropriate clinical decisions, optimal treatment, and improved clinical outcomes in patients with acute coronary syndrome. Developing guidelines that are specifically tailored to the Korean environment is crucial, considering the treatment system, available medications and medical devices, racial differences, and level of language communication. In 2017, the Korean Society of Myocardial Infarction established a guideline development committee. However, at that time, it was not feasible to develop guidelines, owing to the lack of knowledge and experience in guideline development and the absence of methodology experts. In 2022, the National EvidenceBased Healthcare Collaborating Agency collaborated with a relevant academic association to develop internationally reliable guidelines, with strict adherence to the methodology for evidence-based guideline development. The first Korean acute coronary syndrome guideline starts from the 9 key questions for pharmacotherapy.
