Cardiology

Cardiology deals with disorders of the heart as well as parts of the circulatory system. Heart disease leads to a significant number of deaths worldwide.

Heart Disease Definition:

Heart Disease/Cardiovascular disease refers to conditions that involve narrowed/blocked blood vessels, causing heart attacks. 

Heart Disease Includes:

  • Coronary artery diseases (CAD) such as angina and heart attacks
  • Stroke
  • Heart failure
  • Hypertension

 Symptoms of Heart Disease:

  1. Chest Pain - Tightnes/Pressure in chest
  2. Stomach Pain - Burning or Indigestion-type of pain
  3. Feeling hot and sweating
  4. Leg pain - cramping sensation in calves
  5. Choking Sensation
  6. Irregular heartbeat
  7. Swollen ankles
  8. Exhaustion

Causes of Heart Disease

  • High blood pressure
  • Smoking
  • Diabetes
  • Lack of exercise
  • Obesity
  • High blood cholesterol
  • Poor diet
  • Excessive alcohol consumption

Risks that are difficult to prevent: 

  • Age - the risk of getting heart disease is proportional to one's age 
  • Genetics - Having relatives with heart disease increases the risk of heart disease being passed down 
  • Gender - Men are at a greater risk of having heart disease compared to women

Prevention of Heart Disease

Heart disease is the leading cause of death for both men and women. Yet, it is estimated that 90% of heart disease is preventable. Prevention of atherosclerosis involves improving risk factors through: healthy eating, exercise, avoidance of tobacco smoke and limiting alcohol intake. Going for regular health screenings (Blood pressure/ Cholesterol levels/ Diabetes) is also a good habit to inculcate. 

Treating risk factors, such as high blood pressure, blood lipids and diabetes is also beneficial.
