Stress and cardiovascular disease: an update on current knowledge

Area of Science:

• Cardiovascular Science
• Psychosocial Epidemiology

Background:

• Early-life stressors (childhood abuse, socioeconomic adversity) are linked to adult cardiovascular morbidity.
• Social isolation and workplace stress are associated with increased cardiovascular disease risk.

Purpose of the Study:

• To update meta-analyses on the cardiovascular effects of stress.
• To investigate the role of stress in acute cardiac events and disease prognosis.

Main Methods:

• Updated meta-analyses of prospective studies (until 2011).
• Case-crossover studies examining acute coronary syndrome onset.
• Review of stress-induced cardiomyopathy and disease prognosis.

Main Results:

• Social isolation increased coronary heart disease risk by 1.5-fold.
• Workplace stress showed a 1.3-fold excess risk.
• Stress acts as an acute trigger for major cardiac events (pooled relative risk 2.5).

Conclusions:

• Stress is a significant factor in cardiovascular disease development and prognosis.
• Adverse metabolic changes are plausible mechanisms linking stress to cardiovascular disease.
• Integrating stress into cardiovascular research is crucial for future understanding and management.
