Heart/Cardiovascular Disease

• Pathogen is a microorganism that causes disease.
• There are 4 problems that can happen with the heart: Coronary Heart Disease, Faulty Valves, Heart Failure and Extreme Blood Loss.
• Faulty Valves: When the valve is stiff and leaks blood into the heart. Causing backflow and puts strain on heart.

  
• There are two ways you can replace a faulty valve: Using a Biological Valve (from pig/cattle) or a Mechanical Valve (man made).

  
• Biological Valve: Works well but only last a few years and may transfer disease from organism.

  
• Mechanical Valve: lasts for long but need medication to stop blood clots.

  
• Heart Failure: Requires a heart transplant and donor. Which is not always availiable.

  
• Extreme Blood Loss: Would need artificial blood. Patient has time to produce blood but is for a short time.
