Summary
A new mobile health app, mICardiApp, was developed with heart failure patients and professionals to improve self-management. This validated app offers resources on cardiac rehabilitation, medication, and nutrition, enhancing patient health literacy.
Area of Science:
- Digital health interventions
- Mobile health (mHealth)
- Cardiology and patient self-management
Background:
- Heart failure (HF) management requires enhanced patient engagement and health literacy.
- Existing digital tools may not adequately address the multifaceted needs of heart failure patients.
- Patient-centered design is crucial for effective mobile health applications.
Purpose of the Study:
- To describe the development process of the mICardiApp, a mobile health application for heart failure patients.
- To evaluate the content validity of the mICardiApp through a rigorous validation process.
- To assess the relevance and adequacy of the app's content for improving patient self-management.
Main Methods:
- Content development was guided by literature reviews, patient interviews, and user stories.
- A modified Delphi process involving multidisciplinary experts and patients refined the app's content.
- Content validity was measured using the Content Validity Index (CVI) and Adequacy Index (AI).
Main Results:
- The mICardiApp covers 8 key topics relevant to heart failure self-management.
- The app achieved a high overall Content Validity Index (CVI) of 0.851.
- 57 out of 59 screens demonstrated excellent CVI (≥0.70) for relevance and adequacy.
Conclusions:
- mICardiApp is a validated mobile application designed to enhance health literacy and self-management in heart failure patients.
- The app's content has been rigorously validated for relevance and adequacy by experts and patients.
- mICardiApp shows promise as a tool for improving outcomes in patients with heart failure and multimorbidity.

01:28Mitral Regurgitation IV: Nursing Management
68
Mitral regurgitation (MR) is a condition where the mitral valve does not close properly, leading to the backward flow of blood from the left ventricle into the left atrium during systole. This condition can arise from various causes, including rheumatic fever, infective endocarditis, or degenerative valve disease. Effective nursing management is crucial to optimizing patient outcomes and involves comprehensive assessment and targeted interventions.Comprehensive Patient AssessmentA detailed...

Assessment: Nursing management of patients with cardiomyopathy begins with a thorough assessment of the patient's history, including a family history of cardiomyopathy or sudden cardiac death, personal history of heart disease, hypertension, diabetes, and any alcohol consumption or drug use.During the physical examination, assess vital signs, look for signs of heart failure (such as edema, jugular venous distention, and cyanosis), auscultate for abnormal heart sounds (like murmurs and gallops),...

Managing cardiomyopathy involves addressing underlying or precipitating causes, treating heart failure with medications, and implementing dietary changes and a balanced exercise and rest regimen.Lifestyle ModificationsCardiomyopathy patients should adopt a low-sodium diet to reduce fluid retention and manage heart failure. A personalized exercise and rest plan helps maintain physical fitness without overstraining the heart. Avoiding alcohol and tobacco is essential to prevent further damage to...
