Coronary Artery Disease Diagnosis: 5 Accurate Tests For Heart

Coronary Artery Disease is caused by narrowed/blocked heart arteries, leading to chest pain and shortness of breath. Coronary Artery Disease Diagnosis involves a medical history, exams, and tests like ECGs and angiograms.


Treatment includes lifestyle changes, medications, and procedures like angioplasty or bypass surgery. Early Coronary Artery Disease Diagnosis and management improve outcomes, allowing for healthy, active living.


5 Diagnostic Test For Coronary Artery Disease Diagnosis

Coronary Artery Disease Diagnosis involves tests like ECG, stress test, echocardiogram, angiogram, and blood tests. These tests detect blockages, assess disease severity, and inform treatment plans.


List of coronary artery disease diagnosis tests:

  1. Electrocardiogram (ECG)
  2. Stress test
  3. Echocardiogram
  4. Angiogram
  5. Blood tests


Coronary Artery Disease Test - Drlogy


1. Electrocardiogram (ECG)

  • ECG Measures the electrical activity of the heart to detect abnormal rhythms and damage.
  • It is a non-invasive and painless procedure that takes only a few minutes to perform.
  • It Helps doctors diagnose conditions such as arrhythmias, heart attacks, and coronary artery disease.
Electrocardiogram (ECG) Details
Also Known As EKG
Purpose Diagnose heart rhythm abnormalities
Sample None
Preparation None
Procedure Electrodes attached to chest, limbs
Test Timing 5-10 minutes
Test Price (INR) 500-1500
Result Value Electrical activity of the heart
Normal Value Regular heart rhythm & rate
Accuracy 90-95%
Interpretation Results should be interpreted by a healthcare professional.

ECG test provides non-invasive detection of heart problems. The test is quick and painless with high accuracy. Test timing, preparation and price vary. Normal values can be interpreted by a medical professional in Coronary Artery Disease Diagnosis.


2. Stress Test

  • Measures how well your heart works during physical activity, revealing blockages and other issues
  • Provides information about exercise tolerance, heart rate, and blood pressure response to exertion
  • Can help diagnose coronary artery disease, determine its severity, and guide treatment plans.
Stress Test Details
Also Known As Exercise stress test
Purpose To measure the heart's response to physical activity
Sample None required
Preparation No caffeine or tobacco for several hours before the test
Procedure Exercise stress test
Test Timing About 45 minutes
Test Price (INR) 2,000-5,000
Result Value Coronary artery blockage test
Normal Value Stable heart function or stable vitals
Interpretation Positive results indicate the presence of coronary artery disease

A stress test is an exercise test used to measure the heart's response to physical activity and can help detect blockages in the heart's blood vessels in Coronary Artery Disease Diagnosis.


3. Echocardiogram

  • Accurate, non-invasive imaging of the heart's structure and function.
  • Helps diagnose heart disease, heart attack, valve problems, and more.
  • Provides real-time, moving images that can help guide treatment decisions.
Echocardiogram Details
Also Known As Echo, Echocardiography
Purpose Detect and evaluate CAD
Sample None
Preparation None
Procedure Ultrasound waves on the chest area
Test Timing 30-60 minutes
Test Price (INR) 1,500 - 8,000
Result value Cardiac function assessment
Normal Value 55-70%
Interpretation Done by a cardiologist or specialist

Echocardiogram detects coronary artery disease and evaluates heart function with ultrasound waves. Test is non-invasive and results show ejection fraction and wall motion abnormalities in Coronary Artery Disease Diagnosis.


4. Angiogram

  • Invasive imaging test to detect blockages in blood vessels.
  • Uses contrast dye and X-rays for visualization of blood vessels.
  • Helps in diagnosing heart conditions and guiding treatment plans.
Angiogram Details
Also Known As Coronary angiography
Purpose Visualize coronary arteries and identify blockages
Sample None
Preparation NPO for 6-8 hours prior to the procedure
Procedure X-ray with a contrast dye injected through the catheter
Test Timing 30-60 minutes
Test Price (INR) INR 10,000-25,000
Result value Images of coronary arteries
Normal Value Clear coronary arteries
Interpretation The cardiologist reviews images and identifies blockages or narrowing

Angiogram is a diagnostic test for coronary artery disease, done as an outpatient procedure for INR 10,000-25,000. It involves injecting a contrast dye while taking X-rays to identify blockages. Results provide images for cardiologists to identify narrowing.


5. Blood Tests

  • Measures average blood sugar levels over 2-3 months.
  • Used to diagnose and monitor diabetes.
  • Normal levels range from 4-5.6%. Higher levels indicate poor blood sugar control.
Blood Tests Details
Also Known As Serum analysis
Purpose Diagnose Coronary Artery Disease (CAD)
Sample Blood
Preparation Fasting for 9-12 hours
Procedure Blood Draw
Test Timing 2-4 hours
Test Price (INR) 500-5000
Result Value Various blood markers
Normal Value Varies by specific blood marker
Interpretation A doctor reviews results to determine the presence & severity of CAD

This above table provides information on blood tests for diagnosing coronary artery disease (CAD). Blood markers help determine CAD presence and severity, and normal values vary.


CAD Diagnosis Tests Comparison

Test Type Angiogram Test Echocardiogram Test Blood Tests
Also Known As Coronary Angiography Echocardiography Blood Biomarkers
Purpose To visualize Coronary flow To assess Heart analysis To detect Biomarker
Sample Arterial dye injection Chest ultrasound Blood sample
Preparation 6-hour fasting None None
Procedure Contrast catheterization procedure Cardiac ultrasound imaging performed Blood is drawn from a vein
Test Timing Typically takes 30-60 minutes Typically takes 30-60 minutes 2-4 hours
Test Price (INR) 10,000-50,000 2,000-5,000 500-5,000
Result Value Images of Coronary flow Images of heart analysis Blood biomarker levels
Normal Value Healthy coronary arteries Normal heart analysis Normal biomarker levels
Accuracy High High Biomarker-dependent
Interpretation Abnormal results indicate CAD Abnormal results indicate heart dysfunction Abnormal results indicate potential CAD risk

*Test Price, range, and timing may vary as per location, lab type, and procedure.

Compare angiogram, echocardiogram, and blood tests for diagnosing coronary artery disease. Includes cost, accuracy, and interpretation.


Coronary Artery Disease Differential Diagnosis

Similar Diseases Differentiating Factors
Angina, Heart Attack, Heart Failure Symptoms triggered by physical activity, and blockage of coronary arteries seen on imaging.
Asthma, Pneumonia, Bronchitis Sudden onset of shortness of breath, chest pain, and a blood clot in the lungs.
Heart Attack, Pulmonary Embolism, PE Severe chest pain that radiates to the back, a tearing sensation in the chest.

This table provides differential diagnosis of coronary artery disease with similar diseases and differentiating factors are useful for accurate Coronary Artery Disease Diagnosis.
