Transcript of Coronary Heart Disease

Team DASK Coronary Heart Disease Coronary Heart Disease Build up of fatty deposits on the inner wall of the coronary arteries.
These fatty deposits can build up over time, gradually clogging the arteries.
Known as atherosclerosis. Causes There are no set causes of heart disease but rather risk factors e.g.:
smoking high blood pressure
blood lipids
level of physical activity Chest Pain 'angina pectoris'.
Pain felt during rest is unstable angina
Pain during physical activity is stable angina
Shortness of breath
Not everyone experiences chest pain.
Other symptoms such as fatigue and weakness.
Nausea Signs and symptoms Medical Treatments Angiotensin converting
enzyme (ACE) inhibitors Non-Medicinal Treatments Angioplasty & Stent Implantation
Bypass Surgery
Implantable Cardiac Defibrillators Angioplasty & Stent Implantation Also known as percutaneous coronary intervention
a small balloon is inflated inside coronary arteries to open up an area of your arteries that has become very narrow
Improves blood flow to heart
An expandable mesh tube (a 'stent') is usually put into your artery to keep it open. Bypass Surgery Coronary artery bypass graft surgery (CABG)
a blood vessel is taken from your chest, leg or forearm and grafted to your coronary artery
Lets blood 'detour' past a narrowing in this artery
Improves blood flow to your heart muscle and reduces angina (chest pain) Diagnosis ECG (electrocardiogram)
Blood tests
Echocardiography Implantable cardiac defibrillators (ICD) Source: http://www.nhlbi.nih.gov/health/health-topics/images/angioplasty_2011.jpg Source: http://intensivecare.hsnet.nsw.gov.au/five/images/coronary_artery_bypass.jpg A small device is put into your chest and connected to your heart to monitor and correct your heartbeat.
Stops abnormal heart rhythm by pacing your heart, or in more serious situations, it can give your heart a controlled electric shock to try to return it to its normal rhythm.
Can act as a pacemaker if it is beating very slowly
Collects and stores information about your heart's electrical activity for your doctor to check. Source: http://fromyourdoctor.com/document/Content/cardiology/scd_icd.jpg Scenario Apeksha is 56 years old
Recently diagnosed with coronary heart disease
