Heart and blood vessel disorders

There are clear risk factors that increase your chance of suffering from a cardiovascular disease, these include but are not limited to:

There are disorders that can affect our heart and blood and sometimes these can be self-inflicted or increase the risk of a disorder – some of the risk factors are listed below (this is not an all-inclusive list)

  • Palpitations and panic attacks: there is an awareness of the heart beating. Panic attacks are episodes occurring in anxiety disorders. Symptoms of panic attacks vary and can include palpitations, chest pain, dizziness, chills, nausea, and feelings of unreality.
  • Medical History (family) – if there is a history of heart disease in the family that onsets at early age.
  • Sex/Gender – Men are more prone to heart disease although statistics indicate that after 70 both genders are at equal level of risk.
  • High Blood Pressure
  • Hypertension – this is abnormally high (Normal Blood pressure is 120/180 Hg) whereas hypertension which is defined as a systolic pressure higher than 140mm Hg or diastolic pressure higher than 90 mm Hg. This may occur as a result of age (75 years and above), dietary (poor), lack of sufficient exercise, stress and anxiety, obesity but other factors may influence this developing.
  • Hypotension – this is where blood pressure is low, although this generally is considered healthy it can cause symptoms such as dizziness and fainting where the blood flow to the brain is insufficient or chest pain and shortness of breath where the blood flow to the heart is insufficient.
  • Obesity
  • Poor exercise regime – exercise should be maintained on a regular basis.
  • Cigarette smoking
  • Diabetes Mellitus – Diabetes mellitus (DM), commonly known as diabetes, is a group of metabolic disorderscharacterized by a high blood sugar level over a prolonged period of time
  • Oedema – is the excessive accumulation of interstitial fluid in the body tissues. It results is swelling and puffiness. It may be localised at a site of injury or it may be more generalised. Causes of oedema can range from local injuries to heart or kidney disorders.
  • Palpitations and panic attacks: there is an awareness of the heart beating. Panic attacks are episodes occurring in anxiety disorders. Symptoms of panic attacks vary and can include palpitations, chest pain, dizziness, chills, nausea, and feelings of unreality.
