Myocardial infarction (MI) or acute myocardial infarction (AMI) commonly known as heart attack happens when there is marked reduction or loss of blood flow through one or more of the coronary arteries, resulting in cardiac muscle ischemia and necrosis.
Myocardial infarction is a part of a broader category of disease known as acute coronary syndrome, results from prolonged myocardial ischemia due to reduced blood flow through one of the coronary arteries.
In cardiovascular diseases, the leading cause of death in the United States and western Europe usually results from the cardiac damage or complications of MI. Mortality is high when treatment is delayed and almost one-half of sudden deaths due to an MI occur before hospitalization, within one hour of the onset of symptoms. The prognosis improves if vigorous treatment begins immediately.
Nursing Care Plans
The goals of treatment for myocardial infarction are to relieve chest pain, stabilize heart rhythm, reduce cardiac workload, revascularize the coronary artery, and preserve myocardial tissue.
Here are seven (7) myocardial infarction (heart attack) nursing care plans (NCP):
- Acute Pain
- Activity Intolerance
- Risk for Decreased Cardiac Output
- Risk for Ineffective Tissue Perfusion
- Risk for Excess Fluid Volume
- Deficient Knowledge
- Other Possible Nursing Care Plans
Acute Pain: Unpleasant sensory and emotional experience arising from actual or potential tissue damage or described in terms of such damage; sudden or slow onset of any intensity from mild to severe with anticipated or predictable end and a duration of <6 months.
- Pain, acute
May be related to
- Tissue ischemia (coronary artery occlusion)
Possibly evidenced by
- Reports of chest pain with/without radiation
- Facial grimacing
- Restlessness, changes in level of consciousness
- Changes in pulse, BP
- Verbalize relief/control of chest pain within appropriate time frame for administered medications.
- Display reduced tension, relaxed manner, ease of movement.
- Demonstrate use of relaxation techniques.
|Monitor and document characteristic of pain, noting verbal reports, nonverbal cues (moaning, crying, grimacing, restlessness, diaphoresis, clutching of chest) and BP or heart rate changes.||Variation of appearance and behavior of patients in pain may present a challenge in assessment. Most patients with an acute MI appear ill, distracted, and focused on pain. Verbal history and deeper investigation of precipitating factors should be postponed until pain is relieved. Respirations may be increased as a result of pain and associated anxiety; release of stress-induced catecholamines increases heart rate and BP.|
|Obtain full description of pain from patient including location, intensity (using scale of 0–10), duration, characteristics (dull, crushing, described as “like an elephant in my chest”), and radiation. Assist patient to quantify pain by comparing it to other experiences.||Pain is a subjective experience and must be described by patient. Provides baseline for comparison to aid in determining effectiveness of therapy, resolution and progression of problem.|
|Review history of previous angina, anginal equivalent, or MI pain. Discuss family history if pertinent.||Delay in reporting pain hinders pain relief and may require increased dosage of medication to achieve relief. In addition, severe pain may induce shock by stimulating the sympathetic nervous system, thereby creating further damage and interfering with diagnostics and relief of pain.|
|Instruct patient to report pain immediately. Provide quiet environment, calm activities, and comfort measures. Approach patient calmly and confidently.||Decreases external stimuli, which may aggravate anxiety and cardiac strain, limit coping abilities and adjustment to current situation.|
|Instruct patient to do relaxation techniques: deep and slow breathing, distraction behaviors, visualization, guided imagery. Assist as needed.||Helpful in decreasing perception and response to pain. Provides a sense of having some control over the situation, increase in positive attitude.|
|Check vital signs before and after narcotic medication.||Hypotension and respiratory depression can occur as a result of narcotic administration. These problems may increase myocardial damage in presence of ventricular insufficiency.|
|Administer supplemental oxygen by means of nasal cannula or face mask, as indicated.||Increases amount of oxygen available for myocardial uptake and thereby may relieve discomfort associated with tissue ischemia.|
|Administer medications as indicated:|
|Nitrates are useful for pain control by coronary vasodilating effects, which increase coronary blood flow and myocardial perfusion. Peripheral vasodilation effects reduce the volume of blood returning to the heart (preload), thereby decreasing myocardial workload and oxygen demand.|
|Important second-line agents for pain control through effect of blocking sympathetic stimulation, thereby reducing heart rate, systolic BP, and myocardial oxygen demand.May be given alone or with nitrates. Note: beta-blockers may be contraindicated if myocardial contractility is severely impaired, because negative inotropic properties can further reduce contractility.|
|Although intravenous (IV) morphine is the usual drug of choice, other injectable narcotics may be used in acute-phase and/or recurrent chest pain unrelieved by nitroglycerin to reduce severe pain, provide sedation, and decrease myocardial workload. IM injections should be avoided, if possible, because they can alter the CPK diagnostic indicator and are not well absorbed in underperfused tissue.|
