📚 Cardiac Diet — full study notes
The cheat sheet above is your quick recall card. These notes go deeper — what it is, what to do first, what must be reported, and what to teach.
A cardiac diet is heart-healthy eating that limits sodium, saturated and trans fats, and cholesterol while emphasizing fruits, vegetables, whole grains, and lean proteins. It is prescribed for hypertension, coronary artery disease, heart failure, and after myocardial infarction. The goal is to control blood pressure, lower cholesterol, and reduce cardiac workload.
🔑
Key points
Understand these first
Sodium is usually limited to about 2,000 mg per day to control blood pressure and fluid.
Saturated and trans fats are reduced to lower LDL cholesterol; fried and fatty foods are avoided.
Soluble fiber, omega-3 fish, and unsaturated fats support cardiovascular health.
The DASH eating pattern emphasizes fruits, vegetables, low-fat dairy, and whole grains.
Caffeine and alcohol are moderated, and patients on warfarin keep vitamin K intake consistent.
✅
Nursing priorities
What to do, in order
Teach reduction of sodium and saturated fat with practical food swaps.
Monitor blood pressure, weight, and lipid trends.
Reinforce consistent vitamin K intake if the patient takes warfarin.
Coordinate with the dietitian for an individualized heart-healthy plan.
Assess understanding of label reading for sodium and fat content.
🚩
Red flags — report now
Escalate immediately
Chest pain, dyspnea, or rapid weight gain may indicate worsening cardiac status and require immediate report.
Never advise large erratic swings in vitamin K foods for warfarin patients, as it disrupts anticoagulation.
Sudden 2 to 3 lb daily weight gain in heart failure signals fluid retention.
🧪
Labs & values
Numbers to know
