Ischaemic Heart Diseases

• A type of coronary artery disease caused by arteriosclerosis
• Cause by partial to total occlusion of the lumen of the coronary arteries
• Mainly caused by the deposit of cholesterol on the wall of the coronary arteries
• Sometimes the plaque can get hardened by the fibrous tissue and calcification
• Symptoms and conditions generally depend on the location of the lesion and the severity of the occlusion:

• Angina: Chest pain – can be stable or unstable; occurs during exercise or emotional stress.
• AMI: Acute myocardial infarction – a blockage in the coronary arteries that interferes with the blood flow to a certain part of the heart – can cause damage to that part. 
• Arrhythmias: Irregular and/or abnormal heart beat – caused by ionic & biochemical alterations.
• Heart Block: Electrical conduction problem in the heart muscle.
