Insights

COVID-19 lockdown significantly reduced ischemic stroke (IS) admissions. While numbers increased after easing restrictions, they did not reach pre-lockdown levels, correlating with public transport mobility. Further research on pandemic responses and stroke is needed.

Area of Science:

  • Neurology
  • Public Health
  • Epidemiology

Background:

  • The COVID-19 pandemic lockdown (CPL) led to a global decrease in emergency admissions.
  • Ischemic stroke (IS) consultations and treatments were analyzed before, during, and after CPL.

Purpose of the Study:

  • To analyze the impact of CPL on ischemic stroke (IS) and related consultations.
  • To correlate IS events with mobile phone mobility data during different CPL phases.

Main Methods:

  • Data from 12 hospitals on IS, IV rtPA, and EVT were analyzed from Feb 1 to June 15, 2017-2020.
  • Mobile phone mobility data was correlated with IS event occurrences.

Main Results:

  • A significant reduction in IS, IV rtPA, and EVT cases was observed during CPL compared to pre-lockdown (p<0.048).
  • Post-lockdown, consultations and IS cases increased but remained below pre-lockdown levels.
  • Consultation numbers closely paralleled public transportation mobility data.

Conclusions:

  • Reduced emergency admissions during CPL may be partly due to patients avoiding care and decreased exposure to common viral triggers.
  • The decline in stroke consultations correlated with reduced public transport use.
  • Further studies are needed to compare national responses to the pandemic and stroke incidence.

Regulation of Stroke Volume01:27

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...

Atherosclerosis IV: Nursing Management

Nursing management for a patient with arteriosclerosis involves a comprehensive approach focusing on lifestyle modification, disease monitoring, education, and symptomatic care. Here is an overview of effective nursing strategies:Assessment and Monitoring: Initial and ongoing assessments are crucial. Nurses must document the patient's medical history, including any hypertension, diabetes, hyperlipidemia, and other cardiovascular diseases. Assessments also cover family history and lifestyle...

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...

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...

Steps in Outbreak Investigation

In the ever-evolving field of public health, statistical analysis serves as a cornerstone for understanding and managing disease outbreaks. By leveraging various statistical tools, health professionals can predict potential outbreaks, analyze ongoing situations, and devise effective responses to mitigate impact. For that to happen, there are a few possible stages of the analysis:
