How to Prepare for Heart Surgery: A Patient's Step-by-Step Guide

Written by Admin | May 22, 2026, 12:00:00 PM

Preparing for heart surgery can feel overwhelming. Whether you are scheduled for a routine outpatient cardiac procedure or a more complex intervention, preparation can make the process smoother and reduce anxiety. Knowing what to do—and when to do it—can improve both your surgical experience and recovery.

At Lake Nona ASC, we understand the weight of this journey. Our team is dedicated to guiding patients through each step so they feel informed and supported. This guide covers key preparation steps, from your pre-operative consultation to the day of surgery.

Start with a Full Pre-Op Consultation

The foundation of a successful procedure is the pre-operative consultation. During this visit, your surgical team reviews your medical history, evaluates your current health status, and explains what to expect before and after surgery.


What Happens During Your Pre-Op Visit

Your care team will review:

  • Current medications, including prescriptions, vitamins, and supplements
  • Allergies, especially latex, iodine, or anesthetics
  • Recent lab work and imaging results 

One of the most important outcomes of this visit is receiving medication instructions. Many patients are asked to stop taking blood thinners (anticoagulants) or NSAIDs (like ibuprofen) several days before surgery to reduce bleeding risks.

 

Diagnostic Tests You May Need Beforehand

To confirm you are ready for surgery, your provider may order:

  • EKG (electrocardiogram) to evaluate heart rhythm
  • Chest X-ray to assess lung status
  • Blood work to check kidney function and hemoglobin levels
  • Echocardiogram to evaluate heart structure and function 

Understand Your Medication Instructions

How to prepare for heart surgery effectively hinges on one major factor: medication compliance. Following these guidelines is one of the most important and most overlooked steps in the pre-op process.


Medications to Stop Before Surgery

You may be instructed to temporarily stop:

  • Anticoagulants or blood thinners
  • Aspirin, unless otherwise directed
  • Herbal supplements (like garlic and ginkgo biloba) that may increase bleeding risk
  • Certain diabetes medications due to fasting requirements

Important: Never stop prescribed medications without instructions from your care team.

 

Medications That Are Safe to Continue

Some medications, especially blood pressure medications, are often continued up to the morning of surgery with a small sip of water. Always bring an updated medication list to appointments to avoid confusion.

Follow Your Pre-Surgery Diet and Fasting Guidelines

What you eat—and more importantly, when you stop eating—directly impacts the safety of your anesthesia.

  • When to Stop Eating and Drinking: The general rule is nothing to eat or drink (including water, gum, or mints) after midnight the night before your surgery. If your procedure is in the afternoon, your care team may provide a different fasting window.
  • Pre-Op Nutrition: In the days leading up to surgery, try to avoid heavy, fatty, or high-sodium meals. This helps reduce bloating and keeps your blood pressure stable. Make sure to stay hydrated as well, to help with prep and recovery from surgery.
  • Avoid Alcohol: For at least 48 hours before surgery, avoid alcohol, as it can interfere with anesthesia and contribute to dehydration 

Prepare Your Home for Recovery

Preparation doesn't stop at the doors of the ambulatory surgery center. Having a safe, comfortable space ready for your return is vital for a stress-free recovery.


Setting Up Your Recovery Space

If possible, prepare a comfortable recovery area on the main floor of your home to reduce stair use. Keep important items nearby, including:

  • Easy-to-prepare meals
  • Comfortable clothing
  • Water, chargers, medications, and remote controls

Button-down shirts are often more comfortable for cardiac patients after surgery.

 

Who Should Be With You

For outpatient cardiac procedures, a responsible adult must drive you home after surgery. It is also recommended that someone stay with you for the first 24 to 48 hours to assist with meals, lifting, or other daily tasks.

 

Know What to Bring on Surgery Day

Preparing the night before can reduce stress on surgery day.


Essential Items

Bring:

  • Photo ID
  • Insurance card
  • Imaging discs or reports, if requested
  • Completed patient paperwork

What to Wear

  • Choose loose, comfortable clothing.
  • Leave valuables and jewelry at home.
  • Remove nail polish, as it may interfere with monitoring equipment
  • Wear glasses instead of contact lenses if possible.
