Abstract

Insights

Mean platelet volume (MPV) is higher in patients with patent foramen ovale (PFO) who experience stroke or TIA. This finding may help identify PFO patients at high risk for cardioembolic stroke.

Area of Science:

  • Cardiology
  • Neurology
  • Hematology

Background:

  • Patent foramen ovale (PFO) is frequently observed in cryptogenic stroke patients.
  • Mean platelet volume (MPV), a marker of platelet reactivity, is elevated in individuals with PFO compared to the general population.

Purpose of the Study:

  • To determine if MPV differs between patients with PFO and stroke/TIA (symptomatic) and those with asymptomatic PFO.
  • To evaluate MPV as a potential indicator for symptomatic PFO.

Main Methods:

  • Retrospective analysis of 108 patients under 55 with PFO.
  • Comparison of hemogram parameters, specifically MPV, between symptomatic (stroke/TIA) and asymptomatic PFO groups.

Main Results:

  • MPV was significantly higher in the symptomatic PFO group (median 10.0 fl) versus the asymptomatic group (median 8.56 fl).
  • An MPV cut-off of 9.0 fl demonstrated 70% sensitivity and 86% specificity for identifying symptomatic PFO.

Conclusions:

  • Elevated MPV is associated with symptomatic PFO.
  • MPV may serve as a supplementary risk factor for identifying PFO patients at elevated risk of cardioembolic stroke.

Regulation of Stroke Volume

The regulation of stroke volume, which is the amount of blood the heart pumps out during each heartbeat, is critical for maintaining a healthy circulatory system. Stroke volume is influenced by three main factors: preload, contractility, and afterload.
Preload refers to the degree of stretch on the heart before it contracts. It's analogous to the stretching of a rubber band; the more it's stretched, the more forcefully it snaps back. This concept is encapsulated in the Frank-Starling law of the...

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 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...

Formation of the Platelet Plug

The platelet phase, the second stage of hemostasis, commences around 15-20 seconds after an injury. It follows and overlaps with the vascular phase, during which blood vessels constrict to minimize blood loss.
As the injured blood vessel contracts, endothelial cells undergo contraction, revealing collagen fibers in the basement membrane and underlying connective tissue. Furthermore, the plasma membrane of endothelial cells becomes adhesive, preparing the site for platelet adhesion. Platelets...

Structure and Function of Platelets

The cell fragments known as platelets are disc-shaped, with an average diameter of about 3 μm and a thickness of roughly 1 μm. They play a crucial role in the body's vascular clotting system, which also involves plasma proteins, blood cells, and blood vessel tissues.
Platelets are continually replenished, circulating in the bloodstream for 9-12 days before being removed by phagocytes, primarily in the spleen. A microliter of circulating blood contains between 150,000 and 450,000...
