Summary: This paper presents a systematic review of the use of sensors to measure different physical parameters during the performance of 6MWT, focusing on various diseases, sensors, and implemented methodologies. The analysis discovered that the measurements of 6MWT are primarily performed with inertial and magnetic sensors, and most research studies related to this test focus on multiple sclerosis and pulmonary diseases.

Summary: This study aimed to predict adverse events during 6MWT using continuous physiological parameters and demographic variables. The results showed that features related to blood oxygen were the most important and those related to heart rate were the most numerous. The LightGBM model had the highest AUC, with Logistic Regression following closely behind. The mMRC and Borg scales had the lowest performance in predicting adverse events.

Summary: This study aimed to identify the factors independently associated with the six-minute walk test (6MWT) at the 4-6-week follow-up after cardiac surgery and develop an equation to predict the 6MWT during this period. Retrospective analysis of patient data showed that 6MWT at discharge was correlated with 6MWT at the 4-6-week follow-up, as well as regular exercise, age, gender, and preoperative New York Heart Association (NYHA) classification. An equation was generated based on these factors to predict 6MWT at 4-6 weeks after hospital discharge.

Summary: In patients with heart failure, effective cardiac resynchronization therapy induced reverse myocardial remodeling over three months, with significantly decreased ROCK activation in circulating leukocytes. This suggests that reduced ROCK activation in circulating leukocytes may reflect reverse cardiac remodeling in heart failure patients.

Summary: The six-minute walking test (6MWT) has high test-retest reliability when used to assess individuals with stroke. However, other types of reliability, as well as SEM and MDC, require further investigation in populations with stroke.

Summary: The study emphasizes the importance of regular and actual walking ability testing in patients with stable CAD to obtain their cardiorespiratory fitness, rather than simply predicting it from regression equations obtained from non-representative or non-comparable samples.

Summary: This study aimed to investigate the predictive value of Big endothelin-1(ET-1) for LVRR and prognosis in patients with DCM. The study found that Big ET-1 was independently associated with LVRR and had prognostic implications, which might help to improve the risk stratification of patients with DCM.

Summary: Physical activity is effective for breast cancer patients, with the use of adapted target heart rate for exercise intensity. The 6MWT-HR and CPET provide useful information for prescribing exercise programs before and after treatment. This method is beneficial for patients' recovery and physical health post-treatment.

Summary: A smartphone application was developed for cardiac patients to conduct a six-minute walk test at home. Through a prospective study of 102 cardiovascular disease patients, the optimal conditions were identified, and it was demonstrated that random walk and standardized walk tests have the same accuracy.

Summary: This study aimed to evaluate the predictive value of the GRACE risk score in acute pulmonary embolism (PE) patients for 30-day mortality and the need for thrombolytic treatment. The study found that the GRACE risk score, along with the PESI score, were independent risk factors associated with 30-day mortality and the need for thrombolytic treatment. The GRACE risk score showed high sensitivity and specificity in predicting mortality, and its combination with the PESI score helped define high-risk PE patients and predict poor prognosis.

Summary: Transthoracic echocardiography (TTE) is commonly used to evaluate isolated tricuspid regurgitation (TR), but there is limited research comparing its quantification with magnetic resonance imaging (MRI). In this study, a novel TTE algorithm was developed to identify severe TR based on TTE parameters. The algorithm had a higher accuracy than the current guidelines' criteria in detecting severe TR by MRI.

Summary: This article presents a case of a patient with known situs inversus who underwent cardiac catheterization and was found to have chronic total occlusion in the right coronary artery. Situs inversus is a rare congenital abnormality characterized by the inverted position of chest and abdominal organs. Cardiac catheterization is uncommon in patients with this particular abnormality, highlighting the importance of customizing techniques to engage coronary arteries and optimize guide support for percutaneous coronary intervention if needed.

Summary: This study evaluated the angiogenic capacity of adipose tissue in patients undergoing cardiac surgeries and found that patients with coronary artery disease (CAD) had reduced angiogenic capacity in their pericardial adipose tissue. Gene expression analysis revealed upregulated expression of the anti-angiogenic gene TSP-1 in CAD patients, with no significant differences in other angiogenic factors. Additionally, inhibiting TSP-1 expression significantly improved angiogenic deficiency in CAD patients.

Summary: The current guidelines recommend prophylactic implantable cardioverter-defibrillator (ICD) for patients with symptomatic heart failure (HF) and low left ventricular ejection fraction. However, not all patients will benefit from ICD treatment. This study evaluated the feasibility of using the MADIT-II-based Risk Stratification Score (MRSS) to predict the survival benefit of prophylactic ICDs in patients with HF. The results showed that different risk subgroups had varying levels of ICD survival benefit.

Summary: Using latent class analysis (LCA), the study identified clinical, demographic, and social subphenotypes in ASCVD population and assessed the risk of all-cause and cardiovascular mortality across different socioclinical classes. The results showed that the younger, female, non-Hispanic Black or Hispanic individuals with a high burden of co-morbidities and unfavorable social determinants of health had the highest risk of mortality in the identified latent classes.

Summary: This study evaluated the rates and causes of 30-day readmissions after discharge for heart failure (HF) as a primary and secondary diagnosis. The findings indicate that efforts to reduce readmission rates should include patients with secondary HF diagnosis, and surveillance should extend to 2 weeks postdischarge to identify at-risk patients.

Summary: This study aimed to examine the relation between reverse septal curvature (RSC) and nonsustained ventricular tachycardia (NSVT) in patients with hypertrophic cardiomyopathy (HCM). The study found that patients with RSC were younger and had a higher incidence of NSVT, and RSC was identified as a strong independent risk factor for NSVT.
