What are the risk factors associated with Coronary Artery Disease (CAD)?

From the Guidelines

The most significant risk factors for coronary artery disease (CAD) include modifiable factors such as hypertension, dyslipidemia, diabetes mellitus, cigarette smoking, obesity, physical inactivity, and poor dietary habits, as well as non-modifiable factors like advancing age, male gender, family history of premature CAD, and certain genetic conditions. These risk factors contribute to the development of atherosclerosis and subsequent cardiac complications by damaging the arterial endothelium, promoting inflammation, and accelerating atherosclerotic plaque formation 1.

Modifiable Risk Factors

• Hypertension: High blood pressure is a major risk factor for CAD, and controlling it through lifestyle changes and medical therapy is crucial for reducing the risk of CAD 1.
• Dyslipidemia: Elevated LDL cholesterol and low HDL cholesterol levels increase the risk of CAD, and managing these levels through lifestyle changes and medical therapy is essential for preventing CAD 1.
• Diabetes mellitus: Diabetes is a significant risk factor for CAD, and controlling blood sugar levels through lifestyle changes and medical therapy is vital for reducing the risk of CAD 1.
• Cigarette smoking: Smoking is a major risk factor for CAD, and quitting smoking is essential for reducing the risk of CAD 1.
• Obesity and physical inactivity: Maintaining a healthy weight and engaging in regular physical activity can help reduce the risk of CAD 1.
• Poor dietary habits: A healthy diet low in saturated fats, trans fats, and cholesterol can help reduce the risk of CAD 1.

Non-Modifiable Risk Factors

• Advancing age: Age is a non-modifiable risk factor for CAD, and the risk of CAD increases with age 1.
• Male gender: Men are at higher risk of CAD than women, especially before the age of 65 1.
• Family history of premature CAD: A family history of premature CAD increases the risk of CAD, and individuals with a family history should be screened for CAD risk factors 1.
• Certain genetic conditions: Certain genetic conditions, such as familial hypercholesterolemia, can increase the risk of CAD 1.

Emerging Risk Factors

• Elevated inflammatory markers: Elevated levels of inflammatory markers, such as C-reactive protein, can increase the risk of CAD 1.
• Homocysteine levels: Elevated homocysteine levels can increase the risk of CAD, especially in individuals with a family history of CAD 1.
• Certain coagulation factors: Certain coagulation factors, such as factor V Leiden, can increase the risk of CAD 1.

In conclusion, identifying and managing these risk factors is crucial for preventing CAD and reducing the risk of cardiac complications. By prioritizing lifestyle changes and medical therapy, individuals can significantly reduce their risk of CAD and improve their overall health outcomes 1.

Risk Factors for Coronary Artery Disease (CAD)

The following are some of the key risk factors associated with CAD:

• Modifiable risk factors:
  • Smoking 2, 3, 4, 5
  • Hypertension 2, 3, 4, 5
  • Diabetes 2, 3, 4, 5
  • Hyperlipidemia 2, 4, 5
  • Obesity 4, 5
  • Low high density lipoprotein (HDL) cholesterol 3, 5
  • High low-density lipoprotein (LDL) cholesterol 5
  • High triglycerides 5

  • Family history of coronary artery disease 3
  • Age 6
  • Gender 6
• Lifestyle risk factors:
  • Sedentariness 5
  • Alcohol dependence 5
  • Low educational attainment 5
• Other risk factors:
  • Psychosocial stress 4
  • Homocystinuria 4

Association of Risk Factors with CAD

Studies have shown that the management of modifiable risk factors can reduce the risk of CAD and its associated complications 2, 3, 5. The eradication and management of CAD have been established through extensive studies and trials 4.

Prevention of CAD

Prevention of CAD can be achieved through a combination of lifestyle modifications and pharmacological interventions 2, 4, 5. This includes reducing LDL-cholesterol levels, decreasing blood pressure, discontinuing smoking, and managing diabetes and hyperlipidemia 2, 3, 4, 5.
