CARDIO (ANGINA PECTORIS) Flashcards
Is a clinical syndrome usually characterized by episodes of paroxysms of pain or pressure in the anterior chest
Angina pectoris
Angina pectoris is cause by
Insufficient coronary blood flow
Resulting In a decrease oxygen supply when there is increased myocardial demand for oxygen in response to physical exertion or emotional stress
Insufficient coronary blood flow
There are five classifications or types of angina
stable
Unstable
Intractable or Refractory
Variant
Silent schemia
There is predictable and consistent pain that occurs on exertion and is relieved and or nitroglycerine
Stable Angina
The symptoms increase in frequency and severity and may not be relieved with the rest or nitroglycerine
Unstable Angina
There is severe incapacitating chest pain
Intractable or Refractory Angina
There is a pain attack
at rest, with reversible ST segment elevation and thought to be caused by coronary artery vasospasm
Variant Angina
There is objective evidence of ischemia, But the patient reports no pain
Silent Ischemia
Angina is usually caused by
artherosclerotic disease
When there is blockage in a coronary artery, Flow cannot be increased, ans ischemia results which may lead to
necrosis or myocardial infarction
Several factors are associated with angina
Physical exertion
Exposure to cold
Eating a heavy meal
Stress
Stress causes the release of ______ which increase blood pressure, heart rate and myocardial workload
catecholamines
Clinical manifestations of angina
Chest pain
Numbness
Shortness of breath
Pallor
Is usually initiated at the onset of chest pain in an attempt to increase the amount of oxygen delivered to the myocardium and reduce pain.
Oxygen Therapy
Gives long-term and short-term reduction of myocardial oxygen consumption through selective vasodilation within 3 minutes
Nitroglycerin
Reduces myocardial oxygen consumption by blocking beta adrenergic stimulation of the heart
Beta blockers
have negative inotropic effects
Calcium channel blockers
prevent thrombus formation
anticoagulants
Secondary to CAD evidence by chest pain or other prodomal symptoms
Ineffective cardiac tissue perfusion
Nursing diagnoses
Death anxiety
Deficient knowledge
Noncompliance
Nursing interventions for a patient with angina pectoris include
Treating angina
Reducing anxiety
Preventing pain
Decreasing oxygen demand
