Objectives: The aim of the study was to evaluate the clinical outcomes of patients with lung cancer in whom left ventricular ejection fraction (LVEF) was reduced.
Methods: A total of 9814 patients with lung cancer who underwent pulmonary resection from 2010 to 2018 were included for the study. Fifty-six (0.57%) patients had LVEFs ≤45% and we performed propensity score matching (1:3) to compare postoperative clinical outcomes and survival in 56 patients (reduced LVEF group) with those in 168 patients with normal LVEFs (nonreduced LVEF group).
Results: The data of the reduced LVEF group and nonreduced group were matched and compared. The 30- (1.8%) and 90-day (7.1%) mortality rates were higher in the reduced LVEF group than those (0% for both 30- and 90-day mortality rates) in the nonreduced LVEF group (P < 0.001). The estimated rates of overall survival at 5-year point were similar in the nonreduced LVEF group (66.0%) and in the reduced LVEF group (60.1%). The estimated rates of overall survival at 5-year point were almost the same between in the nonreduced and reduced LVEF groups for clinical stage 1 lung cancer (76.8% vs 76.4%, respectively), but for stages 2 and 3, they were significantly better in the nonreduced LVEF group than in the reduced LVEF group (53.8% vs.39.8%, respectively).
Conclusions: Lung cancer surgery for selected patients with reduced LVEFs can yield favourable long-term outcomes despite the relatively high early mortality rate. A careful patient selection and meticulous postoperative care could further improve clinical outcome with reduced LVEF.

Left bundle branch pacing (LBBP) is an emerging physiological pacing technique characterized by stable pacing parameters and a narrower QRS duration. This study aims to compare the long-term efficacy and safety of biventricular pacing (BIVP) and LBBP in patients with heart failure with reduced ejection fraction (HFrEF) and complete left bundle branch block (CLBBB). A retrospective analysis was conducted on 35 patients with chronic HFrEF accompanied by CLBBB treated at our center from April 2018 to October 2022.

Background: Sodium glucose transporter 2 inhibitor (SGLT2i) is the latest guideline-directed medical therapy for patients with heart failure, as it has demonstrated favorable cardiovascular outcomes in heart failure (HF) patients with or without diabetes. Furthermore, SGLT2i has effectively improved cognitive function in older adults with diabetes and HF. However, the effects of SGLT2i on cognitive function and brain mitochondrial function in rats with ischemic HF have never been investigated.

Purpose: Heart failure (HF) is a clinical syndrome in which structural or functional abnormalities of the heart result in impaired ventricular filling or ejection capacity. In order to improve the adaptability of models to different patient populations and data situations. This study aims to develop predictive models for HF risk using six machine learning algorithms, providing valuable insights into the early assessment and recognition of HF by clinical features.

The left ventricular pressure-strain loop (PSL) is a new technique based on ultrasound for noninvasive quantitative evaluation of global and local myocardial work (MW). This study is aimed at evaluating improvement factors of patients with heart failure (HF) reduced ejection fraction (HFrEF) using the PSL technique. A total of 88 patients with HF were enrolled in this study, which had ≤ 40% left ventricular ejection fraction (LVEF).

Aims: Patients with cardiomyopathies are a heterogeneous group of patients who experience high morbidity and mortality. Early cardiac assessment and intervention with access to genetic counselling in a multidisciplinary Cardiomyopathy Clinic may improve outcomes and prevent progression to advanced heart failure.
Methods And Results: Our prospective cohort study was conducted at a multidisciplinary Cardiomyopathy Clinic with 421 patients enrolled (42.
