Summary
Low ambient temperatures significantly increase acute myocardial infarction (AMI) risk. A 5°C temperature drop correlates with a 5-6% rise in AMI admissions, highlighting temperature as a key forecasting factor.
Area of Science:
- Environmental Health
- Cardiology
- Epidemiology
Background:
- Previous research on ambient temperature and acute myocardial infarction (AMI) incidence yielded inconsistent findings.
- Understanding environmental impacts on cardiovascular events is crucial for public health.
Purpose of the Study:
- To investigate the independent associations between ambient temperature indices and AMI incidence.
- To quantify the relationship between temperature variations and hospital admissions for AMI in North China.
Main Methods:
- Retrospective analysis of 2033 AMI admissions from 2003-2011.
- Correlation of admission data with local meteorological records.
- Definition and analysis of temperature indices: daily average, extreme low, and daily temperature range.
Main Results:
- A 5°C increase in daily average temperature one day prior was linked to a 5% decrease in AMI admissions.
- A 5°C increase in daily average temperature two days prior correlated with a 6% decrease in AMI admissions.
- A 2°C increase in daily temperature range two days prior was associated with a 4% rise in AMI admissions.
Conclusions:
- Low ambient temperatures demonstrate a significant association with AMI incidence.
- Ambient temperature serves as a vital factor for predicting and warning about AMI occurrences.

01:21Association Areas of the Cortex
9.3K
Association areas are regions of the cerebral cortex that do not have a specific sensory or motor function. Instead, they integrate and interpret information from various sources to enable higher cognitive processes such as memory, learning, and decision-making. Some key association areas include the following:
Prefrontal Association Area: This area is located in the frontal lobe and is involved in planning, decision-making, and moderating social behavior. It connects with primary motor areas,...

1.3K
Associative learning is a fundamental concept in behavioral psychology, wherein a connection is established between two stimuli or events, leading to a learned response. This process is critical in understanding how behaviors are acquired and modified. Conditioning, the mechanism through which associations are formed, can be divided into two main types: classical conditioning and operant conditioning, each elucidating different aspects of associative learning.

01:25Body Temperature
4.3K
The body's temperature, measured in degrees, is determined by the balance between heat production and dissipation to the surrounding environment. For instance, if exercising vigorously, the body will produce more heat, causing sweat and dissipating that heat. Despite extreme environmental conditions and physical exertion, the human temperature-control system maintains a constant core body temperature (the temperature of deep tissues, which are the tissues located beneath the skin and other...

01:07Body Temperature
1.4K
Body temperature reflects the equilibrium between heat production and heat loss within the body. Most heat is generated by metabolically active tissues, particularly the liver, heart, brain, kidneys, and endocrine organs. At rest, skeletal muscles contribute 20–30% of total heat production, but during vigorous exercise, this can increase up to 30–40 times.
The average body temperature is approximately 37°C (98.6°F) and typically ranges from 36.1–37.2°C...

2.7K
The somatosensory cortex in the parietal lobes is crucial for interpreting sensory data such as touch, temperature, and proprioception. The somatosensory cortex, situated in the parietal lobes, plays a vital role in interpreting sensory information like touch, temperature, and proprioception—awareness of body position. This specialized brain region features an organized structure wherein neurons at the top primarily process sensations originating from the lower body. In contrast, those at...

15.7K
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.
