What to bring:

Bring your doctor's prescription or test requisition, a valid photo ID, and your corporate health insurance card if using cashless OPD. Wear short sleeves or clothing with sleeves that roll up easily.

When does a doctor order Cardiac PET CT?

Cardiologists order Cardiac PET CT when a patient presents with chest pain, exertional shortness of breath, palpitations, or unexplained fatigue. It is also routinely ordered in cardiovascular risk stratification for adults above 35 with hypertension, diabetes, a high BMI, a sedentary lifestyle, or a first-degree relative who experienced a cardiac event before 60.

Who should get Cardiac PET CT done in Chennai?

Tamil Nadu is reported to have among India's highest coronary artery disease rates. The Madras Diabetes Research Foundation has found elevated cardiovascular risk factors in a significant share of Chennai's urban adults , particularly in high-stress professional zones like Nungambakkam, Anna Nagar, and Adyar. Cardiac PET CT is used in advanced cardiac imaging panels when precise information about blood flow and heart muscle health is needed. Doctors may order it for people with chest pain, abnormal stress tests, unexplained breathlessness, or prior heart attacks to check for blockages, ischemia, scar tissue, or inflammation. Adults above 35 in Chennai , particularly those working in Ashok Nagar, Nungambakkam, and other urban centres , should have cardiac markers tested annually even without symptoms. Smokers, people with high blood pressure, a sedentary desk job, BMI above 25, or a first-degree relative with a heart attack before 60 face elevated risk that annual testing actively manages.

What conditions can Cardiac PET CT help diagnose?

An elevated LDL with low HDL indicates dyslipidaemia , the primary driver of coronary artery disease. Elevated triglycerides above 500 mg/dL require specific treatment. Troponin above the 99th percentile indicates myocardial injury. High-sensitivity CRP above 2 mg/L indicates vascular inflammation that independently increases cardiac risk beyond what lipids alone predict.

What do Cardiac PET CT results mean?

LDL above 130 mg/dL: elevated risk , your cardiologist will advise dietary changes or statin therapy based on your overall risk score. LDL above 190 mg/dL may indicate familial hypercholesterolaemia. HDL below 40 mg/dL (men) or 50 mg/dL (women): reduced protection. Triglycerides above 200 mg/dL: diet, alcohol, or diabetes-related. Troponin above the 99th percentile: heart muscle injury , may signal a heart attack, especially if rising on serial testing.

How often should Cardiac PET CT be repeated?

Low-risk adults with a normal lipid profile: annually. Patients on statin therapy: every 6 months to confirm LDL is meeting the treatment target. Post-cardiac event patients: every 3 to 6 months as directed by their cardiologist. Patients with familial hypercholesterolaemia: every 3 months until stable on treatment.
