Insights

The COVID-19 pandemic caused a 55% rise in ST-elevation myocardial infarction (STEMI) cases, leading to delayed treatment and doubled mortality rates. Prompt STEMI diagnosis and treatment are crucial, even during global crises.

Area of Science:

  • Cardiology
  • Public Health
  • Epidemiology

Background:

  • The COVID-19 pandemic significantly impacted acute coronary syndromes (ACS) care.
  • National lockdowns in Italy led to patient delays in seeking medical help due to contagion fears, particularly for ST-elevation myocardial infarction (STEMI).

Purpose of the Study:

  • To evaluate ACS admissions, time to presentation, and clinical outcomes during the pandemic year 2020.
  • Comparison of ACS patient data from 2020 with a historical cohort from 2019 at a Milan cardiovascular hub.

Main Methods:

  • Retrospective analysis of hospital database records for ACS patients.
  • Comparison of patient cohorts admitted in 2020 (pandemic) versus 2019.

Main Results:

  • A 55% increase in ACS cases was observed in 2020 (599 cases) compared to 2019 (386 cases).
  • Late clinical presentations were associated with a threefold increase in cardiogenic shock.
  • Mortality rates for ACS patients more than doubled in 2020 compared to 2019.

Conclusions:

  • The study highlights the severe consequences of delayed STEMI diagnosis and treatment during the COVID-19 crisis.
  • Emphasizes the critical need for maintaining universal and prompt STEMI care protocols, irrespective of global health emergencies.

Types of Limits II01:24

Types of Limits II

When observing how a curve behaves near a specific point along the horizontal axis, there are cases where the curve’s height increases or decreases without limit as the position draws closer to that point. The curve does not settle at any particular value; instead, the values grow more extreme—upward or downward—the nearer they get. No defined value exists exactly at that location, yet the surrounding behavior becomes more dramatic, indicating a sharp change in direction.The...

Pareto Chart00:52

Pareto Chart

A Pareto chart is a bar graph or a combination of both line and bar graphs. The bar lengths represent the individual values or the frequency, while the lines represent the cumulative total values. In this chart, the longest bars are arranged on the left and the shortest bars on the right, which makes it easier to read and interpret the data. It can also be called a Pareto diagram or Pareto analysis.
The Pareto chart is named after the Italian economist Vilfredo Pareto, who described the Pareto...

Types of Skewness01:09

Types of Skewness

If the frequency distribution of a data set is more inclined towards smaller or larger values, the distribution is said to be skewed. If data values are skewed to the right, then the distribution is called positively skewed. Conversely, if the plot is skewed to the left, the distribution is called negatively skewed.
For instance, in the middle of a pandemic, the geographical distribution of vaccine coverage may be positively skewed towards populations in the global north countries. However,...

Residuals and Least-Squares Property

The vertical distance between the actual value of y and the estimated value of y. In other words, it measures the vertical distance between the actual data point and the predicted point on the line
If the observed data point lies above the line, the residual is positive, and the line underestimates the actual data value for y. If the observed data point lies below the line, the residual is negative, and the line overestimates the actual data value for y.
The process of fitting the best-fit...

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:

Cumulative Frequency Distribution01:04

Cumulative Frequency Distribution

A cumulative frequency distribution is another type of frequency distribution. Instead of reporting how many data values fall in some classes, it reports how many data values are contained in either that class or any class to its left. Technically, it means the sum of frequencies of the class and all the classes below it in a frequency distribution. A cumulative frequency is calculated by adding the frequency of each class lower than the corresponding class interval or category. In general, a...
