Why Heart Health Screenings Matter
Heart disease remains the leading cause of death globally, but many cardiovascular conditions are preventable or manageable when detected early. Regular heart health screenings can identify risk factors before they develop into serious problems.
Key Statistics
- • Heart disease causes 1 in every 5 deaths in the United States
- • Many people don't know they have cardiovascular risk factors
- • Early detection can reduce heart attack risk by up to 80%
- • Regular screenings can add years to your life
Heart screenings help detect conditions like high cholesterol, high blood pressure, diabetes, and other cardiovascular risk factors that often have no symptoms in their early stages.
Essential Heart Health Screenings
Basic Screenings
- • Blood pressure measurement
- • Cholesterol and lipid panel
- • Blood glucose testing
- • Body mass index (BMI)
- • Waist circumference
Advanced Tests
- • Electrocardiogram (ECG/EKG)
- • Echocardiogram
- • Stress testing
- • Calcium scoring CT scan
- • Carotid ultrasound
Cholesterol and Lipid Testing
Understanding Your Lipid Panel
| Test | Optimal | Borderline | High Risk |
|---|---|---|---|
| Total Cholesterol | < 200 mg/dL | 200-239 mg/dL | ≥ 240 mg/dL |
| LDL (Bad) | < 100 mg/dL | 100-159 mg/dL | ≥ 160 mg/dL |
| HDL (Good) | ≥ 60 mg/dL | 40-59 mg/dL | < 40 mg/dL |
| Triglycerides | < 150 mg/dL | 150-199 mg/dL | ≥ 200 mg/dL |
Preparation for Cholesterol Testing
- • Fast for 9-12 hours before the test (water is okay)
- • Avoid alcohol for 24 hours before testing
- • Continue taking medications unless instructed otherwise
- • Inform your doctor about any recent illness or stress
Blood Pressure Monitoring
Blood Pressure Categories
Systolic < 120 and Diastolic < 80
Systolic 120-129 and Diastolic < 80
Systolic 130-139 or Diastolic 80-89
Systolic ≥140 or Diastolic ≥90
Home Monitoring Tips
- • Use a validated automatic cuff
- • Measure at the same time daily
- • Sit quietly for 5 minutes before measuring
- • Keep feet flat on floor
- • Take multiple readings
- • Record all measurements
Advanced Cardiac Tests
Electrocardiogram (ECG/EKG)
Records the electrical activity of your heart to detect irregular heartbeats, heart attacks, or other heart problems.
When Recommended:
- • Chest pain or shortness of breath
- • Family history of heart disease
- • Before starting exercise programs
- • Routine screening after age 40
What It Detects:
- • Irregular heartbeats (arrhythmias)
- • Previous heart attacks
- • Heart muscle thickness
- • Poor blood flow to heart
Stress Testing
Evaluates how your heart performs during physical activity, typically on a treadmill or stationary bike.
Types of Stress Tests:
- • Exercise stress test
- • Nuclear stress test
- • Stress echocardiogram
- • Pharmacological stress test
Preparation:
- • Wear comfortable shoes and clothes
- • Avoid caffeine for 24 hours
- • Don't eat 3 hours before test
- • Bring medication list
Calcium Score CT Scan
Measures calcium deposits in coronary arteries to assess cardiovascular disease risk.
| Calcium Score | Risk Level | Meaning |
|---|---|---|
| 0 | Very Low | No calcium detected |
| 1-10 | Low | Minimal plaque |
| 11-100 | Moderate | Mild plaque buildup |
| 101-400 | High | Moderate plaque |
| >400 | Very High | Extensive plaque |
When to Get Screened

- • Sedentary lifestyle
Understanding Your Results
Questions to Ask Your Doctor
- • What do my results mean for my heart health?
- • How do my results compare to previous tests?
- • What is my overall cardiovascular risk?
- • Do I need additional testing?
