Summary
Psychological stress is a significant independent risk factor for coronary heart disease (CHD). This study found high or moderate stress in most patients undergoing bypass surgery, highlighting stress management for CHD patients.
Area of Science:
- Cardiology
- Psychology
- Public Health
Background:
- Coronary heart disease (CHD) is a leading global cause of death, significant in Pakistan.
- The link between stress and CHD is under-examined in local contexts.
- Patients undergoing coronary artery bypass grafting (CABG) may experience high stress, increasing adverse event risk.
Purpose of the Study:
- To investigate the association between psychological stress and coronary heart disease.
- To determine if stress is an independent risk factor for CHD in patients undergoing CABG.
Main Methods:
- A cohort of 60 patients admitted for CABG at Civil Hospital Karachi was evaluated.
- A stress evaluation scale was used to assess stress levels.
- Data collected between January 1 and March 31, 2012.
Main Results:
- Stress was identified as a significant independent risk factor for CHD.
- 60% of patients exhibited high stress (p=0.025), and 36.7% had moderate stress (p=0.0025).
- Stress showed relationships with patient age, sex, BMI, blood group, and myocardial infarction incidence.
Conclusions:
- Psychological stress is independently and causally associated with coronary heart disease.
- The impact of stress on CHD risk is comparable to conventional risk factors.
- Further consideration of stress in CHD management is warranted.

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.

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...

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...

Chronic stress profoundly affects mental health, significantly influencing mood, behavior, and overall quality of life. Research closely links chronic stress with mental health conditions such as depression, anxiety, and substance use disorders. Ongoing exposure to stress can lead to physiological and psychological changes, initiating a cycle of emotional distress and maladaptive coping mechanisms.

Stress is a multifaceted response to events perceived as challenging or threatening, highlighting physical, emotional, cognitive, and behavioral reactions. Physically, stress can lead to fatigue, sleep disruptions, and various health issues such as frequent colds, chest pains, and nausea. Emotionally, it can manifest as anxiety, depression, irritability, and anger triggered by both minor and major life events. Cognitively, it may result in difficulty in concentration, memory, and...

Coronary Artery Disease (CAD) originates from a series of events that impair the function of coronary arteries, the blood vessels responsible for delivering oxygen-rich blood to the heart muscle. The pathophysiology of CAD is closely linked to atherosclerosis, a chronic inflammatory and lipid-driven condition affecting the vascular endothelium.1. Endothelial DamageThe process begins with damage to the vascular endothelium, which serves as a protective barrier between the blood and the vessel...
