Insights

Acute aortic dissection shows distinct onset patterns, occurring more frequently in the afternoon and winter months. These temporal variations highlight potential triggers for this serious cardiovascular event.

Area of Science:

  • Cardiovascular Medicine
  • Epidemiology
  • Medical Statistics

Background:

  • Acute aortic dissection (AAD) is a life-threatening condition with significant morbidity and mortality.
  • Understanding the temporal patterns of AAD onset may provide insights into its pathophysiology and potential preventive strategies.

Purpose of the Study:

  • To investigate the periodic changes and temporal patterns in the onset of acute aortic dissection.
  • To analyze onset regularities based on time of day, weekday, month, and season.

Main Methods:

  • Retrospective analysis of clinical data from 1,121 patients with AAD treated between 2010 and 2016.
  • Statistical analysis of disease onset timing across different diurnal periods, weekdays, months, and seasons.

Main Results:

  • The peak onset period for AAD was in the afternoon (13:00-18:00), with lower frequency in the early morning (1:00-6:00).
  • Monday showed the highest incidence of AAD onset, while Friday had the lowest.
  • January and winter months exhibited a higher frequency of AAD onset compared to July and summer.
  • No significant differences in onset patterns were observed across age groups (≥65 vs <65), or in patients with or without hypertension or Marfan syndrome.

Conclusions:

  • Acute aortic dissection exhibits significant periodic changes in onset, with a predilection for the afternoon and winter.
  • These findings suggest that environmental and physiological factors may influence the timing of AAD events.
  • Further research into circadian and seasonal influences could inform proactive management and prevention of aortic dissection.

The Periodic Table03:25

The Periodic Table

As early chemists discovered more elements, they realized that various elements could be grouped by their similar chemical behaviors. One such grouping includes lithium (Li), sodium (Na), and potassium (K). All of these elements are shiny, conduct heat and electricity well, and have similar chemical properties. A second grouping includes calcium (Ca), strontium (Sr), and barium (Ba), which also are shiny, good conductors of heat and electricity, and have chemical properties in common. However,...

Periodic Classification of the Elements04:00

Periodic Classification of the Elements

The periodic table arranges atoms based on increasing atomic number so that elements with the same chemical properties recur periodically. When their electron configurations are added to the table, a periodic recurrence of similar electron configurations in the outer shells of these elements is observed. Because they are in the outer shells of an atom, valence electrons play the most important role in chemical reactions. The outer electrons have the highest energy of the electrons in an atom...

Effective Value of a Periodic Waveform01:07

Effective Value of a Periodic Waveform

The concept of effective value, the root mean square (RMS) value, is crucial in understanding electrical circuits and power delivery. This idea emerges from the necessity to measure the effectiveness of a voltage or current source in supplying power to a resistive load.
The effective value of a periodic current represents the direct current (DC) that conveys the same average power to a resistor as the periodic current itself. This concept is crucial when assessing AC circuits. To determine the...

The Periodic Table and Organismal Elements

Elements are the smallest units of matter that cannot be broken down further by chemical processes. There are 118 known elements, but not all of these are naturally occurring, and only a few of them are essential for life. Living matter is composed primarily of carbon, nitrogen, hydrogen, and oxygen, with smaller amounts of other elements like calcium, phosphorus, potassium, and sulfur. Other elements are also necessary for life but only in trace amounts.

Aortic Regurgitation I: Introduction01:15

Aortic Regurgitation I: Introduction

IntroductionAortic regurgitation is characterized by the backward flow of blood from the aorta into the left ventricle during diastole and arises from the improper closure of the aortic valve. This condition results in left ventricular volume overload and can stem from both acute and chronic etiologies, each contributing uniquely to the disease's progression and symptomatology.Acute and Chronic CausesAcute aortic regurgitation often results from events that suddenly impair the integrity of the...
