Stress and Cardiovascular Disorders
acute and chronic stress affects different aspects of the cardiovascular system, for example:
- hypertension (high blood pressure)
- coronary heart disease (CHD)
cardiovascular disorders are affected by lifestyle but stress might also cause cardiovascular disorders, for example:
- stress activates the sympathetc branch (SNS) of the ANS, leading to contriction of blood vessels and a rise in blood pressure and heart rate
- increased heart rate may wear away the lining of blood vessels
- stress leads to increased glucose levels, leading to clumps blocking the vessels
Cardiovascular disorders and anger (acute)
Williams et al (2000)
Aim: to see whether anger was linked to heart disease:
Method: 13,000 people answered a 10 question anger scale. No pp's suffered from heart disease and 6 years later, 256 of pp's had experienced heart attacks.
Findings: Those who scored highest on the anger scale were 2.5 times more likely to have a heart attack than those with the lowest anger ratings.
Conclusion: This suggests anger may lead to cardiovascular disorders - 'individuals who find themselves prone to anger might benefit from anger…
