Nursing care plan for myocardial infarction: ranked diagnoses, goals and rationales
Written and reviewed by Kevin Patel, MSN, RN, CCRN · 5 min read · Updated November 2026
Short answer
In a nursing care plan for myocardial infarction, the priority is ongoing ischemic chest pain, written as acute pain or decreased cardiac tissue perfusion, because pain means heart muscle is still at risk. Risk for decreased cardiac output from arrhythmias or pump failure follows, then activity intolerance, anxiety and readiness for cardiac rehabilitation teaching.
The MI plan in table form, top problem first
This plan fits a hypothetical 58-year-old admitted with substernal pressure radiating to the left arm, diaphoresis and nausea. Medications, reperfusion and oxygen orders come from the prescriber and protocol, so the interventions below are the nurse's assessments, timing and reports.
| Nursing diagnosis or problem | Goal or outcome | Interventions | Rationale |
|---|---|---|---|
| 1. Acute pain related to myocardial ischemia | Reports chest pain relieved within 30 minutes of treatment and no recurrence during the shift | Rate pain and character, obtain a 12-lead ECG with each new episode per protocol, give ordered antianginal and antiplatelet therapy, check blood pressure before nitrates, keep at rest | Persistent pain signals ongoing ischemia, so relieving it protects muscle, not only comfort |
| 2. Risk for decreased cardiac output | Heart rhythm, blood pressure and mental status stay at baseline; new changes reported at once | Continuous cardiac monitoring, lung sounds and new murmurs each assessment, urine output, skin temperature and capillary refill | Arrhythmias, heart failure and cardiogenic shock are the complications that kill after MI |
| 3. Activity intolerance | Walks the hall without chest pain, dyspnea or a heart rate rise beyond the ordered limit by day 3 | Progress activity as ordered, check vital signs before and after, stop and report if chest pain or dyspnea appears | Damaged muscle limits output, and graded activity tests tolerance safely |
| 4. Anxiety or fear | States two ways to cope and rates anxiety lower by discharge | Explain each procedure briefly, keep a calm environment, invite questions, involve family | Fear raises heart rate and oxygen demand, and depression and anxiety are common after MI |
| 5. Readiness for enhanced health management | Describes warning signs, medication purpose and the cardiac rehab plan before discharge | Teach to call 9-1-1 for chest pain, explain each discharge medicine, refer to cardiac rehabilitation | Supervised rehab lowers risk after MI, and adherence prevents a second event |
The ECG with each new pain episode matters because the rhythm strip and ST changes can reveal extension of the infarct that the patient describes only as pain coming back.
Chest pain is a perfusion problem first, comfort second
Students often place decreased cardiac output first and pain lower, treating pain as comfort. In MI, unrelieved pain is the bedside sign of ischemia still happening, so the two problems are linked and pain sits at the top while it is active. Once pain resolves, cardiac output monitoring becomes the lead problem.
MSD Manuals notes that about 20 percent of acute MIs are silent and up to 30 percent may be silent in patients with diabetes. That is why the plan does not rely on pain alone. Dyspnea, new nausea, sweating or a rhythm change in a patient without pain still counts as a cue for the cardiac output row.
Complication cues that move cardiac output to the top
MSD Manuals names cardiogenic shock as the largest cause of in-hospital death in STEMI patients treated with PCI. The nursing cues are falling blood pressure, cool clammy skin, confusion and low urine output. New crackles and dyspnea point to left ventricular failure. A new soft blowing murmur at the apex can mean papillary muscle dysfunction with mitral regurgitation.
MSD Manuals describes right ventricular infarction as hypotension with distended neck veins and clear lung fields, which is easy to mistake for a milder problem. A practical rule for the plan: check blood pressure before any nitrate and report hypotension rather than giving the next tablet. A friction rub heard within hours of onset suggests pericarditis rather than MI, a separate comparison page on this site.
Diagnostic statement, goals and how evaluation works
For the hypothetical patient: Acute pain related to decreased coronary blood flow to the myocardium as evidenced by substernal pressure rated 8 out of 10 radiating to the left arm, diaphoresis, guarding and heart rate 108. A measurable goal is pain rated 0 to 2 within 30 minutes of treatment with no recurrence over 8 hours.
Evaluation compares each finding to its goal. If pain returns, the plan is not met and the nurse repeats the ECG and notifies the prescriber per protocol. For activity, NHLBI describes cardiac rehabilitation as a supervised program, often 36 sessions over 12 weeks, so a discharge goal can be a scheduled rehab referral, not just a statement that the patient understands.
Hypothetical question: which MI client needs the nurse first?
Hypothetical scenario, not a real NCLEX item: on day 2 after MI, four findings arrive together. The patient is worried about returning to work, asks when they may shower, has a heart rate of 92 after walking to the bathroom, or now has new crackles at both bases with a respiratory rate of 26.
The new crackles and fast breathing come first because they suggest pump failure, a cardiac output problem. Worry about work is real and belongs to the anxiety row later in the shift. A heart rate of 92 after exertion is within what many activity protocols allow, and the shower question is teaching.

Substernal pressure radiating to neck, back or arms with dyspnea and diaphoresis; about 20% of MIs silent and up to 30% in diabetes; cardiogenic shock as largest cause of in-hospital death after PCI for STEMI; apical murmur from papillary muscle dysfunction; early friction rub suggests pericarditis; cardiac rehab recommended.
Heart Attack - Recovery | NHLBI, NIH. Cardiac rehabilitation as a supervised program often 36 sessions over 12 weeks, call 9-1-1 for symptoms of a second heart attack, depression and anxiety common after a heart attack, take medicines as prescribed.

Common questions
What is the priority nursing diagnosis for myocardial infarction?
While chest pain is active, acute pain related to myocardial ischemia, or decreased cardiac tissue perfusion, ranks first because pain means ongoing muscle injury. Once pain is relieved, risk for decreased cardiac output from arrhythmias, heart failure or shock becomes the lead problem.
What are nursing interventions for myocardial infarction?
Assess pain and obtain an ECG with new pain per protocol, give ordered therapies, check blood pressure before nitrates, keep continuous cardiac monitoring, listen for crackles and new murmurs, progress activity as ordered, reduce anxiety and teach warning signs and cardiac rehab.
How do you write a care plan for myocardial infarction?
Gather cues such as pain rating, ECG, vital signs and lung sounds, choose nursing diagnoses those cues support, rank them by perfusion and safety, set measurable goals with time frames, list nursing actions with rationales, then evaluate each shift against the goals.
