Insights

During France's first COVID-19 lockdown, stroke admissions significantly decreased by 18.42%. This drop in stroke hospitalizations was likely due to the pandemic, not a change in stroke incidence.

Area of Science:

  • Neurology
  • Public Health
  • Epidemiology

Background:

  • The COVID-19 pandemic significantly impacted healthcare systems globally.
  • The first French lockdown (spring 2020) presented unique challenges for non-COVID-19 patient care.
  • Understanding the pandemic's effect on acute conditions like stroke is crucial.

Purpose of the Study:

  • To analyze stroke admission trends in France during the initial COVID-19 pandemic peak.
  • To quantify the change in stroke hospitalizations from January 2019 to June 2020.

Main Methods:

  • Nationwide cohort study utilizing the French national hospital admissions database (PMSI).
  • Inclusion of all hospitalizations with a stroke diagnosis between January 2019 and June 2020.
  • Bayesian modeling to compare slope gradients of stroke admissions across pre-epidemic, epidemic peak, and post-epidemic phases.

Main Results:

  • Stroke hospitalizations declined sharply from March 10, 2020 (slope: -11.70).
  • Admissions began to recover from March 22 to May 7, 2020 (slope: 2.090).
  • A total decrease of 18.42% in stroke admissions was observed in March-April 2020 compared to 2019, affecting ischemic strokes, transient ischemic attacks, and hemorrhagic strokes.

Conclusions:

  • A significant decrease in stroke hospitalizations occurred in France during the first COVID-19 lockdown.
  • This decline is unlikely attributable to a spontaneous change in stroke incidence.
  • The findings suggest a direct or indirect impact of the COVID-19 pandemic on stroke care access and management.

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...

Prevalence and Incidence01:08

Prevalence and Incidence

In statistical epidemiology and health sciences, two essential metrics—prevalence and incidence—are fundamental for understanding disease dynamics within a population. These measures enable public health officials, epidemiologists, and researchers to assess the burden of diseases, allocate resources effectively, and design impactful public health policies and interventions.
Prevalence indicates the proportion of individuals in a population who have a specific disease or health...
