Summary
Optical coherence tomography reveals differences in blood coagulation between stroke patients and healthy individuals. Stroke patients
Area of Science:
- Biomedical Engineering
- Neurology
- Hematology
Background:
- Hemostasis is crucial for stopping bleeding but its role in stroke requires more study.
- Ischemic stroke is a common vascular event.
- Hypercoagulable states may contribute to stroke pathogenesis.
Purpose of the Study:
- To investigate differences in blood coagulation dynamics in acute ischemic stroke patients.
- To explore the potential of optical coherence tomography (OCT) in assessing coagulation.
- To determine if stroke impacts the randomness of the coagulation process.
Main Methods:
- Collected fresh whole blood from 61 acute ischemic stroke patients and 18 healthy controls.
- Utilized optical coherence tomography (OCT) imaging (OCT1300SS system) to analyze blood coagulation.
- Processed OCT images using ImageJ, analyzing gray value metrics (mean, integrated density, skewness, kurtosis).
Main Results:
- Optical coherence tomography detected intrinsic differences in mean gray value and integrated intensity during coagulation.
- Data distribution analysis confirmed these observed differences between patient groups.
- Coagulation in stroke patients exhibited a more symmetrical gray value distribution compared to controls.
Conclusions:
- Normal blood coagulation is not a random process.
- The coagulation process in acute ischemic stroke patients appears more randomized.
- OCT imaging shows potential for differentiating coagulation characteristics in stroke.

Coagulation
1.4K
Colloidal solids are solid particles suspended in solution. They are usually negatively charged, attracting a compact primary layer of positively charged ions, which attract more counterions to form an electrical double layer. Electrostatic repulsion between the charged double layers prevents the particles from colliding, stabilizing the colloids. These solids are often undesirable because they can contain toxins that are difficult to remove. Coagulation is a technique that helps aggregate and...

Coagulation
10.4K
The coagulation phase is a critical part of the body's process to prevent blood loss following injury to blood vessels. It involves chemical reactions that form a clot to seal the injured area. The clotting process begins shortly after injury, within 15-20 seconds for severe damage and 1-2 minutes for minor injuries.
During the coagulation phase, clotting factors, or procoagulants, play a vital role in initiating and progressing the coagulation cascade. This cascade is a series of reactions...

Regulation of Stroke Volume
5.1K
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...

Ischemic Heart Disease: Overview
3.4K
Ischemic heart disease occurs when the heart's blood supply dwindles, causing an ominous lack of oxygen and nutrients. This deficiency, stemming from reduced or obstructed blood flow, spells danger, leading to heart muscle damage and dysfunction.
Atherosclerosis, the primary malefactor, orchestrates this dangerous condition. It manifests as the accumulation of fatty deposits, akin to insidious plaques, within arterial walls. As time elapses, these plaques metamorphose, hardening and...

Introduction
Acute pharyngitis is the inflammation of the back of the throat (pharynx), commonly resulting in a sore throat. It is a frequently encountered condition that prompts individuals to seek medical advice.
Classification
Acute pharyngitis can be categorized based on its underlying cause:

Cardiac Output and Stroke Volume
4.8K
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.
