  • Sedentary, physical activity and sports.
  • Overweight and obesity.
  • Prolonged stress can damage arteries and worsen other risk factors for heart disease.
  • Hypercholesterolemia causes the formation of atherosclerotic plaques.
  • Hypertension can lead to hardening and thickening of the artery walls, narrowing blood vessels.
  • Diabetes: Heart disease is a dangerous complication of diabetes.
  • Advanced age increases your risk of artery stenosis, weakening or hypertrophy.
  • Family factors (in the family someone has heart disease).

In addition, some tests to diagnose cardiovascular disease include:

  • Magnetic resonance imaging (MRI).
  • ECG (ECG).
  • Holter tracker.
  • Echocardiography – Cardiac Doppler.
  • Cardiac catheterization.
  • Computerized tomography of the heart (CT scan).

3.2. Treatment
Depending on the condition, the doctor will prescribe different treatments. Some commonly used methods, for example:

  • Antibiotics are used for heart infections, and the types of heart disease control drugs depend on the type of heart disease the patient has.
