Ch. 23 Coronary Vascular Disorders

stable angina

type of angina that is predictable, and can be relieved with rest or nitroglycerin

unstable angina

type of angina in which pain increases with severity and frequency, not relieved by rest or nitroglycerin

intractable/refractory angina

severe, incapacitating chest pain

variant angina

pain at rest with reversible ST-segment elevation

silent ischemia

objective finding of ischemia through ECG/EKG without complaint of pain

Location differentiation for MI

Anterior
Inferior
Posterior
Lateral

Timing differentiation of MI

Acute
Evolving
Old

Acute differentiation of MI

known as the immediate/active phase
ECG reveals acute electrical/functional changes

Evolving differentiation of MI

known as the intermediate phase
ECG reveals permanent damage

Old differentiation of MI

change in presence of Q waves without change to others, image reveals scar tissue

immediate management of MI

supplemental oxygen
nitroglycerin
Aspirin

Nursing interventions for MI (name 6)

Promote tissue perfusion
Relieve Pain
Monitor s/s of ischemia
Improve respiratory function
Reduce anxiety
Monitor for potential complications
Promote home, community based, and transitional care

PCI stands for…

Emergent Percutaneous Coronary Intervention

PCI mechanism of action

catheter is inserted (through the groin or wrist) to unblock a coronary artery

what are common agents of thrombolytic therapy?

alteplase, reteplase, tenecteplase

contraindications of thrombolytic therapy

active bleeding or bleeding disorders

Name 2 reperfusion procedures for angina

CABG - coronary artery bypass graft
PTCA - percutaneous transluminal coronary angioplasty
