Insights

Workplace stress and heavy physical labor significantly increase the risk of acute myocardial infarction (heart attack) in men living in Kiruna. Conversely, having good job control reduces this risk.

Area of Science:

  • Cardiology
  • Occupational Health
  • Public Health

Background:

  • Kiruna, located north of the Arctic Circle, exhibits high mortality from ischemic heart disease.
  • Understanding psycho-social risk factors is crucial for targeted preventive measures.

Purpose of the Study:

  • To investigate psycho-social risk factors associated with acute myocardial infarction (AMI) in men in Kiruna.
  • To identify specific occupational and social factors contributing to heart disease risk.

Main Methods:

  • A case-control study design was employed.
  • 219 male patients with first AMI (1973-1985) were compared with 438 age-matched male controls.
  • Statistical analysis adjusted for biomedical risk factors.

Main Results:

  • Mental and physical stress at work (OR 3.5) and heavy physical work (OR 1.5) were linked to increased AMI risk.
  • Good control over job tasks showed a reduced risk (OR 0.7).
  • Recent migration to Kiruna was an independent predictor of AMI.

Conclusions:

  • Certain male subgroups in Kiruna face high AMI risk due to adverse work and social factors.
  • Findings highlight the need for preventive strategies addressing occupational and social determinants of heart health.

Factors Influencing Heart Rate01:30

Factors Influencing Heart Rate

The heart rate, or pulse rate, is a vital indicator of cardiovascular health. It reflects the number of times the heart beats per minute. Various physiological and environmental factors influence heart rate, increasing or decreasing cardiac output. Understanding these factors is crucial for assessing heart function and identifying potential health issues.
Let us explore the significant factors affecting heart rate, including age, body temperature, posture, acute pain, chemical influences,...
Ischemic Heart Disease: Overview01:17

Ischemic Heart Disease: Overview

Ischemic heart disease occurs when the heart's blood supply dwindles, causing an ominous lack of oxygen and nutrients. This deficiency, stemming from reduced or obstructed blood flow, spells danger, leading to heart muscle damage and dysfunction.
Atherosclerosis, the primary malefactor, orchestrates this dangerous condition. It manifests as the accumulation of fatty deposits, akin to insidious plaques, within arterial walls. As time elapses, these plaques metamorphose, hardening and narrowing...

Coronary Artery Disease I: Introduction

Coronary Artery Disease (CAD): An Overview with Scientific InsightsCoronary Artery Disease (CAD), often referred to as C-A-D, is a prevalent blood vessel disorder classified under the broader category of atherosclerosis. Atherosclerosis is a pathological process characterized by the hardening and narrowing of arteries due to the accumulation of atherosclerotic plaques. These plaques are composed of cholesterol, fatty substances, inflammatory cells, calcium, and fibrin, reducing blood flow to...

Coronary Artery Disease IV: Preventive Measures

Effective preventive measures for coronary artery disease (CAD) focus on controlling modifiable risk factors, including cholesterol abnormalities and lifestyle changes.Cholesterol ManagementFirst, the Mediterranean diet and the American Heart Association advocate for maintaining low-density lipoprotein (LDL) cholesterol levels below 100 mg/dL, with a more stringent recommendation of below 70 mg/dL for individuals at high risk. LDL cholesterol, often termed "bad cholesterol," can lead to the...

Atherosclerosis III: Management

Management of atherosclerosis involves an integrated strategy encompassing pharmacological treatment, surgical interventions, lifestyle changes, and nutrition therapy to address the multifactorial nature of the disease.Pharmacological TherapyA cornerstone of atherosclerosis management is the use of pharmacological agents. Statins, such as atorvastatin, are pivotal in inhibiting HMG-CoA reductase, an enzyme that catalyzes an initial step in cholesterol synthesis in the liver. This reduction in...

Psychoneuroimmunology: Cardiovascular Disease

Psychoneuroimmunology (PNI) is a multidisciplinary field that examines how psychological factors, particularly stress, interact with the immune system and impact physical health. Research in PNI has shown that chronic or traumatic stress can disrupt both the hypothalamic-pituitary-adrenal axis and the sympathetic nervous system. These disruptions contribute to serious health conditions, including cardiovascular diseases.
A key area of focus in PNI is the relationship between stress and coronary...
