Silent Threat: Four Non-Invasive Tests to Detect Blocked Arteries, Says Cardiologist
New Delhi, India – September 9, 2025 – Millions unknowingly live with partially or fully blocked arteries, a leading cause of heart attack adn stroke. A cardiologist is urging proactive health monitoring, emphasizing that early detection is crucial for preventing life-threatening cardiovascular events. While chest pain is a well-known symptom, many individuals experience no warning signs until a critical blockage occurs. Fortunately,several accessible,non-invasive tests can reveal arterial health before symptoms manifest.
Cardiovascular disease remains the number one cause of death globally, accounting for an estimated 17.9 million deaths each year, according to the World Health Organization. in India, the prevalence of heart disease is rapidly increasing due to lifestyle changes, dietary habits, and rising stress levels. Identifying arterial blockages early allows for lifestyle modifications, medication, or minimally invasive procedures to restore blood flow and substantially reduce risk. “The key is to be proactive, not reactive,” explains Dr. Anya Sharma, a leading cardiologist at Apollo Hospitals. “These tests provide a window into your cardiovascular system without requiring surgery or extensive recovery time.”
Here are four essential non-invasive tests recommended for assessing arterial health:
1.Electrocardiogram (ECG/EKG): This simple, painless test measures the electrical activity of the heart. While it doesn’t directly show blockages,an ECG can detect signs of heart strain or previous damage caused by reduced blood flow. It’s often the first step in evaluating potential heart problems.
2. Stress Test: Also known as a treadmill test, this evaluates heart function during physical exertion. electrodes monitor the heart’s electrical activity while the patient walks on a treadmill, gradually increasing in intensity. Abnormalities detected during exercise can indicate blockages limiting blood supply.
3.Echocardiogram: This ultrasound of the heart provides detailed images of its structure and function. it can reveal areas of weakened heart muscle,valve problems,or abnormalities in blood flow suggestive of arterial blockages.A stress echocardiogram combines the ultrasound with exercise to assess heart function under stress.
4. Ankle-Brachial Index (ABI): This test compares blood pressure in the ankles to blood pressure in the arms. A meaningful difference can indicate peripheral artery disease (PAD), often a sign of blockages in arteries supplying the legs and feet, and a predictor of potential blockages in the heart. Dr. Sharma notes, “An ABI is a quick and easy screening tool that can identify individuals at higher risk who may benefit from further inquiry.”
Regular check-ups and awareness of family history are also vital components of cardiovascular health. Individuals with risk factors such as high blood pressure,high cholesterol,diabetes,smoking,or obesity should discuss appropriate screening schedules with their healthcare provider. Early detection and intervention are paramount in combating the silent threat of blocked arteries and safeguarding long-term heart health.
