Ischemic Heart Disease: Overview01:17

Ischemic Heart Disease: Overview

1.2K
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...

Regulation of Stroke Volume01:27

Regulation of Stroke Volume

3.2K
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

706
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

2.9K
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...

Issues And Trends In Healthcare Delivery System

5.6K
The issues and trends in healthcare delivery are constantly changing. The COVID-19 pandemic is one recent issue that wreaked havoc on healthcare systems, causing a shortage of healthcare workers, high demand for medicines and supplies, and increased medical expenditure due to a lack of insurance. Other issues include rising healthcare costs and care fragmentation.
Cost Containment
Payment for healthcare services has historically promoted adoption of costly and often unnecessary or inefficient...

Area of Science:

  • Neurology
  • Emergency Medicine
  • Hospital Administration

Background:

  • In-hospital stroke (code stroke) is increasingly common due to rising patient volumes and complexity.
  • Current institutional protocols for in-hospital code stroke vary, leading to inconsistent emergency responses.
  • Studies indicate delays in recognizing and managing acute stroke in hospitalized patients compared to those arriving via the emergency department (ED).

Purpose of the Study:

  • To discuss the current landscape of acute in-hospital code stroke protocols.
  • To review differences in neurologic outcomes between inpatient and ED/out-of-hospital code stroke patients.
  • To propose future directions for in-hospital code stroke paradigms to enhance patient outcomes and care quality.

Main Methods:

  • This commentary reviews existing literature and institutional practices regarding in-hospital code stroke.
  • It analyzes reported challenges in emergency stroke response within hospitals, including team assembly and urgent imaging access.
  • Comparative analysis of neurologic outcomes between inpatient and ED-initiated stroke care is discussed.

Main Results:

  • Delays in activating in-hospital code stroke protocols are associated with increased morbidity, mortality, and healthcare costs.
  • Shared challenges exist in both ED and ward settings, such as ad hoc team formation and urgent imaging requirements.
  • Existing protocols often differ significantly between institutions, impacting response efficiency.

Conclusions:

  • Standardized, team-based emergency response protocols, similar to cardiac arrest responses, are warranted for inpatient acute code stroke.
  • Addressing delays in recognition and management is critical for improving outcomes.
  • Future directions should focus on optimizing in-hospital stroke care paradigms for better patient results and quality of care.
