DEFINITION Angina pectoris is chest pain or
discomfort that occurs when the heart muscle doesn’t get enough blood.
Angina pectoris is chest pain resulting from myocardial ischemia (inadequate blood supply to the myocardium).

Characteristics of angina includes
Onset :- Develop quickly or slowly.
Location :- Slightly to the left of sternum.
Radiation :- Left shoulder and upper and may then travel down the inner aspect of the left arm to the elbow, wrist, fourth and fifth fingers, radiate to right shoulder, neck, jaw, epigastric region.

Duration :- Less than 5 minutes.Sensation :- Like squeezing,
burning, pressing , chocking, aching , pain feels like gas, heartburn.
Severity :- Usually mild or moderate in severity.
Treatment :- The client treated the pain with nitroglycerin. Angina should subside after nitroglycerin use.

Nursing DiagnosisAnxiety related to diagnosis of cardiac
disorder as evidenced by restlessness, tachycardia, and frequently asking questions regarding prognosis.
Acute chest pain related to decreased blood supply to myocardium as evidenced by distraction behaviors such as restlessness, discomfort and fatigue.
![Page 19: Angina pectoris](https://reader036.vdocuments.us/reader036/viewer/2022081520/58a0d47d1a28abeb378b4941/html5/thumbnails/19.jpg)
Ineffective tissue perfusion related to decreased oxygenation of myocardium as evidenced by chest pain, shortness of breath and tachycardia.
Decreased cardiac output related to negative ionotropic changes in the heart secondary to decreased oxygenation of myocardium as evidenced by chest pain, tachycardia and fatigue.

Impaired gas exchange related to decrease cardiac output as evidenced by dyspnea, pallor and fatigue.
Risk for bleeding related to coagulopathies associated with thrombolytic therapy or arterial puncture after angiography.
