Summary
The HeartHealth program, using text messages for cardiovascular patients, reduced healthcare service use. This digital health intervention shows promise for improving patient outcomes and managing chronic conditions effectively.
Area of Science:
- Cardiology
- Digital Health
- Public Health
Background:
- The HeartHealth program is a 6-month text message support initiative for cardiovascular disease patients in Western Sydney, Australia.
- It provides regular, semi-personalized messages with information, advice, and support.
Purpose of the Study:
- To evaluate the impact of the HeartHealth program on healthcare service utilization among cardiovascular patients.
- To assess the effectiveness of text message-based interventions in managing cardiovascular disease.
Main Methods:
- An observational study comparing hospitalization rates between HeartHealth participants and a control group.
- Patients (≥18 years) attending cardiology clinics or discharged from Westmead Hospital (April 2020-April 2022) were invited.
- Primary outcome: all-cause healthcare utilization events within 6 months post-discharge, adjusted for confounders.
Main Results:
- 11,542 patients (4,324 intervention, 7,218 control) were analyzed; mean age 58.8 years, 60.7% male.
- HeartHealth participants showed significantly lower healthcare service event rates (adjusted rate ratio: 0.91; P=0.033).
- Older patients (>65 years) experienced a greater reduction in healthcare utilization compared to younger patients (interaction P=0.043). Program adherence improved diet, physical activity, and medication compliance.
Conclusions:
- Text message-based postdischarge support can potentially decrease healthcare service utilization for cardiovascular disease patients.
- The HeartHealth program demonstrates the value of digital health tools in managing chronic cardiovascular conditions.
- This intervention offers a scalable solution for improving patient self-management and reducing healthcare burdens.

28
IntroductionThe management of Acute Coronary Syndrome (ACS) aims to minimize myocardial damage, preserve myocardial function, and prevent complications.Initial ManagementInpatient management involves continuous cardiac monitoring, preferably in an ICU, focusing on blood pressure, serum sodium, potassium, and creatinine levels, and urine output. Ongoing pharmacologic management is crucial for stabilizing the patient.Supplemental Oxygen: Administer supplemental oxygen if oxygen saturation is...

Additional therapies for treating patients with heart failure (HF) may include procedural interventions, supplemental oxygen, the management of sleep disorders, and nutritional therapy.Procedural InterventionsImplantable Cardioverter-Defibrillator: For patients at risk of life-threatening arrhythmias due to severe left ventricular dysfunction, an Implantable Cardioverter-Defibrillator (ICD) can detect and terminate these arrhythmias, preventing sudden cardiac death and improving survival rates.

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),...

01:30Pulse rhythm
927
Pulse rhythm refers to the pattern of pulsations within specific intervals, offering valuable insights into the regularity or irregularity of the heart's beats as observed through the pattern of pulsation within specific intervals. A regular pulse exhibits a consistent heart rate with uniform waveforms and pulsation force, variations of which can be classified as normal, weak, or bounding.
Conversely, an irregular pulse pattern is termed dysrhythmia, stemming from disruptions in cardiac...

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...

The first step in nursing management of a patient with heart failure involves thoroughly assessing the patient's medical history.Subjective Data: Obtain the patient's medical history of coronary artery disease, hypertension, myocardial infarction, and symptoms like dyspnea, orthopnea, and paroxysmal nocturnal dyspnea.Objective Data: Conduct a physical examination to identify findings such as jugular vein distention, pulmonary crackles, tachycardia, murmurs, peripheral edema, and vital signs,...
