This Concept Map, created with IHMC CmapTools, has information related to: Group Map AMI, circumflex artery ???? posterior left ventricle, ISCHAEMIC HEART DISEASE (IHD) ???? AMI, ATHEROSCLEROSIS ???? RISK FACTORS, HEART ???? CORONARY CIRCULATION, * education * cardiac rehab * lifestyle changes ???? Drugs may include: * ACE inhibitor to address the patient's blood pressure * Beta Blockers for arrythmia's and irregular heart beat * Aspirin for its anti-clotting properties * Anti-cholesterol medications * Anti thrombotic eg Asosantin for reducing future risk of clotting, Glycogen stores decrease as anerobic metabolism begins ???? accumulation of hydrogen ions and lactic acid compromises the myocardium, 3 TYPES ???? VARIANT ANGINA * vasospasm in arteries injured by atherosclerosis * occurs at rest & doesnt respond to nitroglycerine, ANGINA ???? AMI, CORONARY CIRCULATION ???? aorta, MANAGEMENT ???? POST MI MANAGEMENT, MANAGEMENT ???? SURGICAL MANAGEMENT, AMI ???? SIGNS & SYMPTOMS, supply to body ???? right atrium, lungs ???? left atrium, CELLULAR INJURY ???? CELLULAR DEATH, ANGINA ???? * chest pain/discomfort arising from transient myocardial ischaemia * principle cause atherosclerotic stenosis, * after 20 mins of myocaridal ischaemia, irreversible hypoxic injury causes cellular death & tissue necrosis ???? STRUCTURAL CHANGES, left coronary artery ???? circumflex artery, right coronary artery supplies blood to * right atrium * right ventricle * sinoatrial (SA) node * atrioventricle bundle *posterior portion of left ventricle, acidosis may make the myocardium more vulnerable to the damaging effects of lysosomal enzymes and may suppress impulse conduction and contractile function, leading to heart failure ???? myocardial cells deprived of necessary oxygen and nutrients lose contractibility, diminishing the pumping ability of the heart
