Insights

Cardiac rehabilitation (CR) research shows increasing publications, focusing on physical activity, secondary prevention, and quality of life. Global implementation challenges persist, requiring further clinical studies for improved patient outcomes.

Area of Science:

  • Cardiology and Rehabilitation Medicine

Background:

  • Cardiac rehabilitation (CR) is crucial for myocardial infarction (MI) patient recovery, mortality reduction, and quality of life enhancement.
  • Despite established benefits, global CR implementation is inconsistent, necessitating research trend analysis.

Purpose of the Study:

  • To explore research trends, hot topics, and frontiers in cardiac rehabilitation for myocardial infarction patients over 23 years (2000-2023).
  • To map the field's development trajectory and identify areas for future research and improved CR implementation.

Main Methods:

  • Bibliometric analysis of 9,471 papers on CR and MI from the Web of Science core database (2000-2023).
  • Knowledge mapping using VOSviewer and CiteSpace for authors, institutions, and countries.
  • World publication mapping via Scimago Graphica.

Main Results:

  • A steady increase in annual publications on CR post-MI was observed.
  • The United States led in publications, with significant academic institutional contributions and collaborations.
  • Key research areas include physical activity, secondary prevention, risk management, quality of life, mortality, depression, high-intensity interval training (HIIT), and resistance exercise.

Conclusions:

  • Global research output on CR for MI patients is growing, yet implementation faces worldwide challenges.
  • Addressing identified research frontiers like HIIT and resistance exercise is vital.
  • Concerted global efforts are needed for in-depth clinical studies to enhance CR quality and patient outcomes.

Imaging Studies for Cardiovascular System IV: CMRI

Cardiovascular magnetic resonance imaging, or CMRI, is a non-invasive diagnostic test that employs a magnetic field and radiofrequency waves to create precise images of the heart and arteries. It provides comprehensive information about cardiac anatomy, function, perfusion, and tissue characterization without ionizing radiation.IndicationsCMRI diagnoses various heart conditions, including tissue damage from heart attacks, ischemic heart disease, myocarditis, aortic issues (tears, aneurysms,...

Imaging Studies for Cardiovascular System V: CT

Cardiac computed tomography (CT) scanning is an advanced cardiac imaging technique that utilizes CT technology, with or without intravenous (IV) contrast, to produce accurate cross-sectional virtual slices of specific areas of the heart, coronary circulation, and major blood vessels such as the aorta, pulmonary veins, and arteries. The computer processes these slices to generate three-dimensional images. Multidetector CT (MDCT) is a rapid form of CT scanning that captures multiple slices...

Cardiac Output and Stroke Volume01:11

Cardiac Output and Stroke Volume

Cardiac output (CO) is an integral aspect of human physiology, reflecting the heart's efficiency and responsiveness to the body's needs. It represents the volume of blood that the left or right ventricle ejects into the aorta or pulmonary trunk each minute. The CO is calculated by multiplying the heart rate (HR)—the number of heartbeats per minute—by the stroke volume (SV)—the amount of blood pumped out with each heartbeat.
In an average resting adult male, the typical cardiac...

Acute Coronary Syndrome III: Diagnostic Studies

Diagnosing acute coronary syndrome or ACS begins with a thorough patient history. Notable symptoms include central, crushing chest pain radiating to the left arm, neck, jaw, or back, along with shortness of breath, sweating (diaphoresis), nausea, vomiting, dizziness, and palpitations.It is crucial to note any history of cardiac illnesses and assess risk factors, including age, gender, smoking, hypertension, diabetes, hyperlipidemia, and a sedentary lifestyle.During physical examination, vital...
