Insights

Recognizing early warning signs like chest pain and fatigue is key for preventing myocardial infarction (MI). This study found that sex is significantly associated with these prodromal symptoms in at-risk individuals.

Area of Science:

  • Cardiology
  • Preventive Medicine
  • Symptom Research

Background:

  • Prodromal symptoms preceding myocardial infarction (MI) are challenging to identify in at-risk individuals.
  • Research has established the existence of prodromal symptoms, but their association with risk factors requires further investigation.
  • This study aimed to determine the relationship between specific risk factors and baseline prodromal symptoms of MI.

Purpose of the Study:

  • To investigate the association between various risk factors and prodromal symptoms of myocardial infarction.
  • To identify the most frequent prodromal symptoms experienced by patients before MI.
  • To explore the influence of demographic factors, particularly sex, on the prevalence and severity of these symptoms.

Main Methods:

  • A cross-sectional study was conducted with 154 Iranian men and women (mean age 59.62 ± 12.74 years) between 2016-2017.
  • The McSweeney Prodromal Myocardial Infarction Symptom Survey was utilized to assess the frequency and severity of 33 prodromal symptoms and associated risk factors.
  • Data analysis focused on identifying correlations between risk factors and the prodromal symptom scores.

Main Results:

  • The most common prodromal symptoms reported were chest pain/discomfort (64.30%), unusual fatigue (50.60%), and sleep disturbances (20.40%).
  • Women reported a higher number of prodromal symptoms compared to men (mean score 33.26 ± 21.88 vs. 25.48 ± 17.75).
  • Statistical analysis revealed that only sex was significantly associated with the prodromal symptom score (P < 0.05).

Conclusions:

  • Chest pain/discomfort, unusual fatigue, and sleep disturbances are frequently observed prodromal symptoms preceding myocardial infarction.
  • A significant association was found between sex and the experience of prodromal symptoms, highlighting potential gender-specific differences.
  • Early identification of these prodromal symptoms in individuals with risk factors is crucial for the prevention of myocardial infarction.

Cross-Sectional Research

In cross-sectional research, a researcher compares multiple segments of the population at the same time. If they were interested in people's dietary habits, the researcher might directly compare different groups of people by age. Instead of following a group of people for 20 years to see how their dietary habits changed from decade to decade, the researcher would study a group of 20-year-old individuals and compare them to a group of 30-year-old individuals and a group of 40-year-old...

Factors Affecting the Risk of Infection01:26

Factors Affecting the Risk of Infection

The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...

Profile Leveling and Cross Sections01:26

Profile Leveling and Cross Sections

Profile leveling and cross-sections are surveying methods used to determine and document terrain elevations for infrastructure projects such as highways, railroads, canals, and pipelines. These methods provide data for earthwork planning and alignment of proposed routes.  Profile leveling involves measuring elevations along a fixed line to create a vertical terrain profile. A surveyor sets up a leveling instrument at the benchmark (BM) and records a backsight (BS) to determine the...

Spinal Cord: Cross-sectional Anatomy

The cross-sectional anatomy of the spinal cord offers a detailed view of its complex structure and function within the central nervous system. At the core of the spinal cord lies the gray matter, characterized by its butterfly or "H"-shaped appearance in cross-section. This central region is enveloped by white matter, with the overall structure divided into symmetrical halves by the dorsal median sulcus and the ventral median fissure.
Gray Matter and its Components
Central to the gray matter is...

Genome-wide Association Studies-GWAS

Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.
GWAS does not require the identification of the target gene involved in...

Crossing Over01:34

Crossing Over

Unlike mitosis, meiosis aims for genetic diversity in its creation of haploid gametes. Dividing germ cells first begin this process in prophase I, where each chromosome—replicated in S phase—is now composed of two sister chromatids (identical copies) joined centrally.
The homologous pairs of sister chromosomes—one from the maternal and one from the paternal genome—then begin to align alongside each other lengthwise, matching corresponding DNA positions in a process...
