Pulse rhythm01:30

Pulse rhythm

798
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...

Observational Studies

8.6K
Observational studies are a type of analytical study where researchers observe events without any interventions. In other words, the researcher does not influence the response variable or the experiment's outcome.
There are three types of observational studies – Prospective, retrospective, and cross-sectional.
Prospective Study
Prospective studies, also known as longitudinal or cohort studies, are carried out by collecting future data from groups sharing similar characteristics. One...

Longitudinal Research

12.0K
Sometimes we want to see how people change over time, as in studies of human development and lifespan. When we test the same group of individuals repeatedly over an extended period of time, we are conducting longitudinal research. Longitudinal research is a research design in which data-gathering is administered repeatedly over an extended period of time. For example, we may survey a group of individuals about their dietary habits at age 20, retest them a decade later at age 30, and then again...

Pathophysiology of Heart Failure01:17

Pathophysiology of Heart Failure

1.6K
Heart failure (HF) is a progressive syndrome involving ventricles that leads to inadequate cardiac output. It can be classified based on location and output or ejection fraction. Ejection fraction (EF) is an essential measurement in the diagnosis and surveillance of HF. Reduced EF corresponds to systolic heart failure (HFrEF). However, HF with preserved ejection fraction (HFpEF) is becoming increasingly prevalent. Also known as diastolic HF, this form of HF is related to aging. The...

Longitudinal Studies

Longitudinal studies are also widely used in other medical and social science fields. For instance, in cardiovascular research, they can monitor patients' health over decades to identify risk factors for heart disease, such as high cholesterol or smoking, and evaluate the long-term effectiveness of preventive measures. Similarly, in mental health studies, researchers might follow individuals from adolescence into adulthood to understand the development and progression of conditions like...

Area of Science:

  • Biomedical Engineering
  • Health Informatics
  • Chronic Disease Management

Background:

  • Heart failure (HF) impacts over 64 million globally, necessitating improved self-management strategies to reduce healthcare burdens.
  • Current self-management understanding relies heavily on self-report, limiting objective insights into daily life.
  • Wearable cameras present a novel method to explore the lived experiences and daily activities of individuals with HF.

Purpose of the Study:

  • To evaluate the utility of wearable cameras in understanding the daily activities of individuals with heart failure (HF).
  • To assess the effectiveness of the E-Myscéal system in processing and analyzing wearable camera data for HF self-management research.

Main Methods:

  • The "Seeing is Believing (SIB)" study utilized wearable cameras on 30 HF patients for up to 30 days.
  • The E-Myscéal web-based lifelog retrieval system processed image data, using specific search terms for daily activities.
  • Analysis included sensitivity testing of search terms, examination of temporal activity patterns, and comparison of pre- and post-hospitalization data.

Main Results:

  • E-Myscéal demonstrated variable image retrieval sensitivity based on search terms, with eating and drinking yielding the most images.
  • Fewer images were captured for physical activity, screen time, and medication intake, with most activities occurring before noon.
  • Hospitalization led to observable shifts in daily patterns, including increased medication intake and decreased screen time post-discharge.

Conclusions:

  • Wearable cameras provide valuable, objective data on daily activities and self-management behaviors in heart failure (HF) patients.
  • The E-Myscéal system is effective for image retrieval, but careful optimization of search terms is essential for comprehensive analysis.
  • Findings highlight the potential for technology-assisted monitoring to enhance HF self-management interventions.
