1 Angina Pectoris Prepared by : Ansam Sharef Ahmad Aswad
Slide 2-

2 Angina Pectoris Definition : Angina pectoris is a clinical syndrome usually characterized by episodes of pain or pressure in the anterior chest . The cause is usually insufficient coronary blood flow which results in a decreased oxygen supply to meet an increased myocardial demand for oxygen in response to physical exertion or emotional stress.
Slide 3-

3 Pathophysiology Myocardial ischemia can result from: A reduction of coronary blood flow caused by fixed &\or dynamic epicardial artery stenosis. Abnormal constriction or deficient relaxation of coronary artery. Reduce O2-carrying capacity of the blood .

Slide 5-

5 Factors are associated with typical angina pain Physical exertion (increase myocardial o2 demand). Exposure to cold ( cause elevation of BP increase oxygen demand ) Eating heavy meals Stress or any emotion-provoking situation
Slide 6-

6 Type of angina Stable angina: predictable & consistent pain that occurs on exertion and relieved by rest. Unstable angina or preinfarction or cresendo angina: symptoms occur more frequently and longer than stable angina. Intractable or refractory angina: sever incapacitating chest pain.
Slide 7-

7 Type of angina Variant angina or prinzmetals angina : pain at rest with reversable ST-segment elevation, caused by coronary artery vasospasm. Silent ischemia: objective evidence of ischemia (as ECG changes with a test), but pt report no symptom.
Slide 8-

8 Risk Factors for atherosclerosis Family history of premature coronary artery disease. DM, systemic HTN. Cigarette smoking. Hypercholesterolemia. Others as obesity, increase levels of lipoprotein,fibrinogen, s.triglycerides.
Slide 9-

9 Clinical manifestations May produce pain vary in severity from feeling of indigestion to chocking in retrosternal area , radiate to neck , jaw shoulders , inner aspects of upper arms Feeling of weakness or numbness in the arms , wrists and the hands Shortness of breath
Slide 10-

10 Clinical manifestations Pallor, Diaphoresis Dizziness or lightheadedness Nausea and vomiting
Slide 11-

11 Diagnostic findings Often made by evaluating the clinical manifestations of ischemia and the pts history 12-Lead ECG and blood laboratory values help in making diagnosis C-reactive protein ( CRP) is a marker for inflammation of vascular endothelium which caused by CAD
Slide 12-

Slide 13-

13 Diagnostic findings An elevated blood level of homocysteine ,an amino acid proposed as an independent risk factor for cardiovascular disease , but no studies supported the relationship between elevation of homocysteine and atherosclarosis
Slide 14-

14 Medical management for the pt with angina pectoris
Slide 15-

15 The objective is to decrease oxygen demand of myocardium and to increase oxygen supply 1.Nitroglycerin : administered to reduce myocardial oxygen consumption
Slide 16-

16 2.Beta-adrenergic blocking agents : ( propranolol ,metoprolol , atenolol) appear to reduce myocardial oxygen consumption, result in a reduction in heart rate, decreased BP , and reduced myocardial contractility .
Slide 17-

17 3-Calcium channel blocking agents : some decrease sinoatrial node automaticity and node conduction ,resulting in slower heart rate
Slide 18-

18 4- Antiplatelet and anticoagulent medications Aspirin: prevents platelet activation and reduces the incidence of MI and death with CAD Heparin : prevents the formation of new blood clots
Slide 19-

19 Oxygen administration : usually initiated at the onset of chest pain to increase the amount of oxygen delivered to the myocardium and to decrease the pain.
Slide 20-

20 Prevention Self care action plan changing habits. Stop smoking Increase level of exercise Cut down on fatty foods Eat more oats, which decrease cholesterol
Slide 21-

21 Lose wt if u DR. thinks you are overweight. Make sure your BP is not high by regular check Consider another method of contraceptive if you take pill
Slide 22-

22 Nsg process for pt with Angina pectoris Assessment The nurse gather information about the pts symptoms and activities . The nurse may ask about the period that angina last , and if any medication relieve the angina.
Slide 23-

23 Diagnosis Ineffective myocardial tissue perfusion secondary to CAD as evidence by chest pain or equivalent symptoms Anxiety related to fear of death
Slide 24-

24 Diagnosis Noncompliance , ineffective management of therapeutic regimen related to failure to accept necessary lifestyle changes
Slide 25-

25 Planning and goals The major goal include immediate treatment when angina occur , preventing of angina , reduction of anxiety and absence of complications
Slide 26-

26 NSG interventions Treating angina : when pt experiences angina the nurse should direct pt to stop activities and sit or rest in bed in semi-fowler position Reducing anxiety : The nurse should explore and implicate that the diagnosis has for the pt providing information about the illness , treatment and methods of preventing its progression
Slide 27-

27 Preventing pain : when the pt has pain with minimal activity , the nurse alternates the pts activities with rest periods
Slide 28-

28 Evaluation expected pts outcomes may include Reports that pain is relieved promptly Reports decreased anxiety
Slide 29-

29 Understands ways to avoid complications and demonstrates freedom from complications Adheres to self-care program
