Cardiac Output I:Effect of Heart Rate on Cardiac Output01:19

Cardiac Output I:Effect of Heart Rate on Cardiac Output

1.1K
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...

Exercise and Cardiac Output

1.2K
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...

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

Cardiac Output II: Effect of Stroke Volume on Cardiac Output

1.3K
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...

Area of Science:

  • Cardiology
  • Pediatric Health
  • Sports Medicine

Background:

  • Minors are primary consumers of energy drinks (EDs).
  • Concerns exist regarding the cardiovascular effects of EDs in adolescents.
  • Limited research addresses the acute impact of EDs on pediatric cardiac function.

Purpose of the Study:

  • To investigate the acute effects of energy drink consumption on left ventricular (LV) hemodynamics and efficiency.
  • To assess cardiac performance in healthy children and teenagers after consuming EDs versus a placebo.
  • To evaluate the utility of non-invasive LV pressure-volume loops (PVLs) in detecting subtle cardiac changes.

Main Methods:

  • Randomized, single-blind, placebo-controlled, crossover clinical trial design.
  • Inclusion of 24 healthy children and teenagers (mean age 14.90 ± 2.27 years).
  • Non-invasive LV hemodynamics and efficiency assessment using simultaneous echocardiography and blood pressure measurement to generate LV PVLs.

Main Results:

  • No significant differences in conventional LV function parameters between ED and placebo groups.
  • A significant reduction in cardiac efficiency was observed 240 minutes post-ED consumption compared to placebo (p < 0.01).
  • Non-invasive LV PVLs identified decreased cardiac efficiency following acute ED intake.

Conclusions:

  • Acute energy drink consumption is linked to reduced cardiac efficiency in healthy minors.
  • Non-invasive LV PVL analysis is a valuable tool for assessing subtle changes in LV efficiency.
  • Further research is warranted on the long-term effects of EDs on pediatric cardiac structure and function.
