Coronary Artery Disease: Risk Factor Control, Statin Safety, and Heart Attack Warning Signs
Teach control of modifiable risk factors: tobacco cessation, blood pressure below 130/80 mm Hg, the prescribed LDL target, diabetes control, healthy weight, and at least 150 minutes of moderate activity weekly. Teach daily statin use and reporting of unexplained muscle pain, weakness, or dark urine. Take aspirin only when prescribed, and call 911 for chest discomfort lasting more than a few minutes.
Who needs this teaching
Clients with coronary artery disease, including clients with stable angina, a prior myocardial infarction, or a coronary stent, and the family member who shops and cooks. Atherosclerotic plaque narrows the coronary arteries and reduces myocardial blood flow. Control of modifiable risk factors slows plaque progression and reduces the risk of acute coronary syndrome.
The priority teaching points
- Modifiable risk factors. Separate modifiable risk factors (tobacco use, hypertension, elevated LDL cholesterol, diabetes, obesity, physical inactivity) from nonmodifiable risk factors (age, sex, family history). Focus teaching on the factors the client controls.
- Tobacco cessation. Stop all tobacco products, including e-cigarettes, and avoid secondhand smoke. Nicotine causes vasoconstriction, and smoking causes endothelial injury. Offer counseling and prescribed cessation medications.
- Blood pressure and diabetes. Keep blood pressure below 130/80 mm Hg unless the provider sets another goal. For clients with diabetes, the usual A1C target is below 7% (normal A1C is below 5.7%); follow the individualized goal.
- Statin therapy. Take the statin every day as prescribed. Statins lower LDL cholesterol and stabilize plaque. Follow the LDL target the provider sets; many clients with coronary artery disease aim for an LDL below 70 mg/dL. Report unexplained muscle pain, tenderness, or weakness, and dark urine. These indicate myopathy or rhabdomyolysis. Keep lipid panel appointments.
- Heart-healthy eating. Teach a Mediterranean or DASH eating pattern: vegetables, fruits, whole grains, legumes, nuts, fish, and lean proteins. Replace saturated fat (fatty red meat, butter, full-fat dairy) with unsaturated fat such as olive oil. Avoid trans fat. Keep sodium below 2,300 mg daily, or the prescribed limit.
- Weight and activity. Aim for at least 150 minutes of moderate activity weekly, such as brisk walking 30 minutes on 5 days, after provider clearance. Work toward a body mass index of 18.5 to 24.9 and a waist circumference below 40 in (102 cm) for men and 35 in (88 cm) for women. Keep the influenza vaccine current each year.
- Aspirin and emergency action. Take aspirin only when the provider prescribes it. Call 911 for chest pain, pressure, or tightness lasting more than a few minutes or returning, with or without pain in the arm, back, neck, or jaw, dyspnea, diaphoresis, or nausea. Women, older adults, and clients with diabetes frequently present with fatigue, dyspnea, or epigastric discomfort, with or without chest pain. Do not drive to the hospital.
Red flags the client reports
| Call the provider the same day | Call 911 or the local emergency number |
|---|---|
| Unexplained muscle pain, tenderness, or weakness during statin therapy | Chest pain, pressure, or tightness lasting more than a few minutes or returning |
| Dark urine with muscle symptoms: call promptly | Chest discomfort with dyspnea, diaphoresis, nausea, or pain radiating to the arm, back, neck, or jaw |
| Home blood pressure or blood glucose readings repeatedly above the target | New angina, angina at rest, a change in the usual pattern, or syncope |
Teach-back questions
- "Which two risk factors will you work on first?"
- "How many minutes of activity will you aim for each week?"
- "Show me the saturated fat and sodium on this label."
- "Which symptoms will you report while you take your statin?"
- "What will you do if chest pressure lasts more than a few minutes?"
Teaching tips
- Write the client's blood pressure, LDL, and A1C targets on the handout.
- Use examples from the client's usual foods and cooking methods.
- Rehearse the emergency plan: stop activity, call 911, and unlock the door.

Why this matters for the NCLEX
Teaching is effective when the client states, "I will take my statin every day and report muscle pain I cannot explain," and "I will call 911, not drive myself, if chest pressure lasts more than a few minutes." Statements requiring further teaching include, "I will start a daily aspirin on my own," "I will stop my statin once my cholesterol is normal," and "Heart attack pain always travels down the left arm."
Frequently asked questions
Should every client with coronary artery disease start aspirin on their own?
No. Take aspirin only when prescribed. The provider weighs thrombosis prevention against bleeding risk for each client.
Can the client stop the statin when the LDL reaches the target?
No. The LDL reflects ongoing statin therapy. Stopping the statin returns the LDL toward the pretreatment level.
