Insights

Cardiac rehabilitation (CR) is available in only 40% of low- and middle-income countries (LMICs), with patients often bearing the cost. Governments should implement policies to fund CR services for better accessibility.

Area of Science:

  • Cardiology
  • Public Health
  • Health Services Research

Background:

  • Cardiac rehabilitation (CR) availability and characteristics are poorly understood in low- and middle-income countries (LMICs).
  • Understanding these factors is crucial for improving cardiovascular disease (CVD) care globally.

Purpose of the Study:

  • To compare CR availability, program features, and funding in LMICs versus high-income countries (HICs).
  • To identify barriers and facilitators for CR implementation in diverse healthcare settings.

Main Methods:

  • A global cross-sectional online survey of CR programs.
  • Calculation of CR need based on incident ischemic heart disease (IHD) estimates.
  • Analysis using general linear mixed models.

Main Results:

  • CR is available in 39.9% of LMICs, with one spot per 66 IHD patients (vs. 3.4 in HICs).
  • Patients predominantly fund CR in LMICs (65.0%), contrasting with government funding in HICs (60.2%).
  • CR programs in LMICs offer core components consistent with guidelines, with publicly funded programs providing more comprehensive services.

Conclusions:

  • CR availability remains limited in LMICs, despite programs adhering to guidelines.
  • Governmental policies and reimbursement are essential to alleviate patient out-of-pocket expenses for CR.
  • Addressing funding disparities is key to expanding access to CR globally.

Cardiac Output II: Effect of Stroke Volume on Cardiac Output01:22

Cardiac Output II: Effect of Stroke Volume on Cardiac Output

Cardiac output (CO), the amount of blood the heart pumps per minute, is a parameter in cardiovascular physiology determined by stroke volume and heart rate. Stroke volume, the amount of blood pushed from one of the ventricles per heartbeat, is influenced by preload, afterload, and contractility.
Preload
Preload refers to the initial elongation of the cardiac myocytes before contraction and is related to the volume of blood filling the heart at the end of diastole, or end-diastolic volume. The...

Cardiac Output I:Effect of Heart Rate on Cardiac Output

Cardiac Output
Cardiac output (CO) refers to the total amount of blood ejected by one of the ventricles in liters per minute (L/min). In a resting adult, CO ranges from 5 to 6 L/min, adjusting according to the body's metabolic requirements.
Effect of Heart Rate on Cardiac Output
Cardiac output adapts to metabolic demands during stress, physical activity, or illness. The autonomic nervous system regulates heart rate via the sinoatrial node. The parasympathetic nervous system decreases heart...

Cardiac Cycle01:29

Cardiac Cycle

The cardiac cycle refers to the sequence of events that occur in the heart from the beginning of one heartbeat to the next. It's characterized by alternating periods of contraction (systole) and relaxation (diastole) of the heart muscles.
During the cardiac cycle, blood flow through the heart is regulated entirely by changing pressure gradients. This sequence of events begins with the heart in a state of total relaxation, known as mid-to-late diastole, during which blood passively flows from...

The Cardiac Cycle01:13

The Cardiac Cycle

The heart beats rhythmically in a sequence called the cardiac cycle—a rapid coordination of contraction (systole) and relaxation (diastole).
The Process
Electrical signals—sent from the sinoatrial (SA) node in the right atrial wall to the atrioventricular (AV) node between the right atrium and right ventricle—cause both atria to simultaneously contract. When the signal reaches the AV node, it pauses for approximately a tenth of a second, allowing the atria to contract and...

Exercise and Cardiac Output01:17

Exercise and Cardiac Output

Regular physical activity is essential for maintaining cardiovascular health, with aerobic exercises being particularly effective. According to the American Heart Association, 150 minutes of moderate to intense aerobic exercise per week is recommended for a healthy heart. Aerobic activities may include brisk walking, running, bicycling, cross-country skiing, and swimming, ideally performed three to five times per week.
Sustained exercise increases the muscles' oxygen demand, which can be...

Imbalances in Cardiac Output01:26

Imbalances in Cardiac Output

The heart's primary function is to pump blood throughout the body, maintaining a balance between blood sent out (cardiac output) and blood returning (venous return). If this balance is disrupted, it can result in congestive heart failure (CHF), a severe condition where the heart becomes an inefficient pump, leading to inadequate blood circulation.
CHF can occur due to the failure of either side of the heart. Left-side failure leads to pulmonary congestion—the right side continues to send...
