Major circulatory system disorders and treatment



Hypertension: High Blood Pressure

Causes:  diet, stress, inactivity. Effects on body:  Leads to heart disease and possible failure

Arteriosclerosis: Hardening of the Arteries

 Causes: Diet – High in Cholesterol (LDL) and Fats. Effect on body: Causes arteries to become inelastic which can reduce the amount of blood flow in them. This can lead to a heart attack and/or stroke.
               

Atherosclerosis: Narrowing of Arteries




Causes: Fatty deposits within the artery walls from poor diet/fat intake etc. Effect on body:    Narrowing of arteries reduces blood flow to heart and brain which may lead to heart attack and/or stroke.

 Stroke: Loss of blood flow to brain tissue causing cell death

Causes: Any one of the above and others. Effect on Body:  loss of brain function and/or motor control (paralysis), death.

Coronary-blockage:  A blockage in the coronary arteries of the heart.

Causes: Diet, lack of exercise. Effect on Body:      Heart attack, death 
Causes:  diet, stress, inactivity. Effects on body:  Leads to heart disease and possible failure

Treatments for Circulatory System Disorders

Thrombolytics 
Thrombolytics are a class of drugs known as “Clot busting” drugs. These drugs help to bust up blood clots that have formed. They help to clear blocked passageways etc, example;  Streptokinase or t - PA: A Clot busting drug that converts plasminogen to plasmin. Plasmin dissolves the clot

 Angioplasty           
Procedure in which a small catheter (tube) with a balloon attached is inserted into an artery and then inflated.  The inflation helps to stretch the artery in an attempt to increase blood flow to the heart.  Sometimes a Stent (small mesh netting) is put in place to keep the artery open after the balloon is removed

Coronary Bypass Surgery
Surgery in which a healthy blood vessel from another area in the body is used to create a new pathway around a blockage in a blood vessel near the heart, usually a coronary artery.
