Background: Because it is unclear whether implantable cardioverter-defibrillators (ICDs) are equally effective in patients of all ages, we investigated the association of age with long-term clinical outcomes of patients who underwent ICD implantation.
Methods And Results: A total of 416 consecutive patients (mean age: 69 years) from 4 tertiary hospitals who underwent ICD implantation or were upgraded from an existing permanent pacemaker between January 2011 and November 2022 were enrolled and divided into 3 groups based on age: <65 years (n=158), 65-74 years (n=138), and ≥75 years (n=120). We compared the incidence of all-cause death and adverse cardiovascular events, including cardiac death, appropriate ICD therapy, and heart failure hospitalization.
Article Synopsis
- Researchers aimed to create a machine learning tool to automatically assess frailty in elderly heart failure patients, addressing the inconsistency of subjective frailty scales.
- The study involved 417 patients aged 75 and older, using smartphone technology to analyze body motion and determine frailty scores based on key physical features.
- Results showed that the machine learning model demonstrated strong agreement with actual frailty assessments and that higher frailty scores predicted an increased risk of death over a follow-up period.
Article Synopsis
- - The study investigated the link between long-term cardiac troponin levels and adverse events in patients with cardiac sarcoidosis who were treated with prednisolone, involving 63 patients and 463 troponin measurements over about 30 months.
- - Results indicated that a higher cumulative level of troponin over time correlated with a greater risk of serious heart-related issues, such as ventricular tachycardia or sudden cardiac death, occurring in about 19% of patients.
- - The findings suggest that monitoring troponin levels regularly could help identify patients at higher risk for adverse cardiac events, indicating its potential value in clinical settings.
