You should consider a cardiac screening if you have any of these signs and symptoms, including:
- Chest pain and discomfort
- Slow or racing heartbeat
- Fatigue
- Shortness of breath
- Dizziness
- Fluttering in your chest
- Swelling in your feet or abdomen
How to prepare for a cardiac screening?
Different cardiac screening requires different types of preparation. The most common cardiac screening preparations include:
- Blood Pressure Screening:
In this screening test, doctors measure the force of blood against the artery walls. It is a non-invasive test, where certain factors can affect your reading.
How to prepare:
- Prevent the intake of caffeine, alcohol, and tobacco for at least 30 minutes before your screening because it can raise blood pressure temporarily.
- Avoid vigorous exercises at least 30 minutes before the test, which also raises your readings.
- Sit quietly for 5 to 10 minutes before screening to stabilize your heart rate and blood pressure.
- You should wear short-sleeved clothes that allow easy access to your upper arm for accurate cuff placement.
- Cholesterol screening:
In this screening, doctors measure total cholesterol, LDL (bad) cholesterol, HDL (good) cholesterol, and triglycerides. It usually needs fasting for accurate results.
How to Prepare:
- Fasting requirements: For fasting, you need to avoid eating or drinking (except water) for 9-12 hours before the test.
- Avoid consuming alcohol, high-fat, or high-cholesterol foods 24 hours before the screening because they affect your lipid levels.
- Keep yourself hydrated before the screening.
- Schedule your test early in the morning, so that you can complete your fasting period overnight and later consume your breakfast.
- Blood sugar (glucose) screening:
In this test, doctors measure blood glucose levels to find whether you have diabetes or prediabetes. Based on the type of test, you may need to fast.
How to prepare:
- Fasting blood sugar test: Keep a fast (no eating or drinking except water) for at least 8 hours before the test. Bring a healthy snack to eat after the test to normalize your blood sugar levels.
- Non-fasting blood sugar test: You don’t need any specific preparation, except to avoid high-sugar foods and drinks on the day of the test.
- Electrocardiogram (ECG or EKG):
In this test, doctors measure the electrical activity of the heart to detect arrhythmias, heart enlargement, and other heart conditions.
How to prepare:
- Avoid applying any lotions, oils, or creams to your chest or arms on the day of the test because they interfere with electrode placement.
- Wear loose clothes that give easy access to your chest area.
- Remove any jewelry or metal objects that can interfere with the ECG readings.
- Stress test:
In this test, doctors check how well your heart functions under physical pressure. Typically, it is used to diagnose coronary artery disease or to check the severity of existing heart conditions.
How to prepare:
- Avoid consuming anything for 2 to 4 hours before the test.
- Wear comfortable loose clothes and shoes suitable for exercise, such as sneakers or athletic wear.
- Avoid smoking and consuming caffeine at least 24 hours before the test, as they impact your heart rate and blood pressure.
What to expect?
When you go to a doctor’s clinic or hospital for a heart screening, the staff will guide you through the registration process, then send you to the doctor for a physical examination. During a physical exam, they check your history of heart problems, heart rate, blood pressure, eating habits, and physical activity. Additionally, they measure your weight and height. This helps your doctor decide what cardiac screening you need.
During the screening, the doctor may take a blood sample to check cholesterol, blood sugar, and other markers. For an ECG or stress test, electrodes are placed on your chest to monitor your heart’s electrical activity during rest and some physical activity like running.
After the screening, the doctor will discuss the results with you to determine whether you have any irregularities in your test or not. If irregularity is detected, the doctor tailors a treatment plan that may include lifestyle changes, medication, or further testing to prevent further complications while maintaining heart health.
Preparing for cardiac screening is not difficult, as your doctor will guide you with exact guidelines for the recommended cardiac screening test. However, the above-mentioned steps guide you on what to expect before, during, and after a cardiac screening for your heart health.
