Cardiac Imaging and Stress Testing
30 Mar 2026
1. Overview
Coronary Artery Disease (CAD) remains one of the leading causes of mortality worldwide. Early detection through non-invasive techniques like cardiac imaging and stress testing plays a crucial role in preventing adverse cardiac events. This case study highlights how combined diagnostic approaches improved patient outcomes.
2. Patient Profile
- Name: Mr. R (Anonymous)
- Age: 52 years
- Gender: Male
- Medical History:
- Hypertension (10 years)
- Type 2 Diabetes (5 years)
- Sedentary lifestyle
- Family history of heart disease
3. Presenting Symptoms
- Chest discomfort during exertion
- Shortness of breath
- Occasional fatigue
- No prior history of cardiac events
4. Initial Clinical Assessment
- Blood Pressure: 150/95 mmHg
- Resting ECG: Normal
- Cholesterol Levels: Elevated LDL
Due to risk factors and symptoms, further evaluation was recommended.
5. Diagnostic Approach
A. Stress Testing (Treadmill Test – TMT)
- Patient exercised under monitored conditions
- Findings:
- ST-segment depression during peak exercise
- Indication of myocardial ischemia
👉 Suggestive of reduced blood flow to the heart during stress
B. Cardiac Imaging
1. Echocardiography
- Normal resting cardiac function
- Mild left ventricular hypertrophy
2. Myocardial Perfusion Imaging (MPI)
- Reduced perfusion in the anterior wall
- Reversible ischemia detected
3. CT Coronary Angiography
- Significant narrowing (~70%) in the Left Anterior Descending (LAD) artery
6. Diagnosis
Stable Coronary Artery Disease with inducible ischemia
7. Treatment Plan
- Medical Management:
- Antiplatelets
- Statins
- Beta-blockers
- Lifestyle modifications
- Intervention:
- Percutaneous Coronary Intervention (PCI) with stent placement
8. Outcome
- Symptoms significantly reduced post-treatment
- Improved exercise tolerance
- Follow-up imaging showed restored blood flow
- Patient adopted healthier lifestyle habits
9. Key Learnings
Why Stress Testing Matters
- Detects hidden ischemia not visible at rest
- Helps assess functional capacity of the heart
Why Cardiac Imaging is Critical
- Provides anatomical clarity
- Identifies exact location and severity of blockage
Combined Approach Benefits
- Accurate diagnosis
- Better risk stratification
- Personalized treatment planning
10. Conclusion
This case demonstrates that early use of stress testing combined with advanced cardiac imaging can:
- Detect coronary artery disease before major events
- Guide precise interventions
- Improve long-term patient outcomes
