Tests That Can Detect Blocked Arteries Before Symptoms | Doctor Explains

Could your arteries be blocked without you knowing? Blocked arteries do not always cause obvious symptoms straight away. In some people, arteries can narrow silently over many years, and symptoms may not appear until the narrowing becomes significant. That is why understanding the right tests — and knowing which symptoms should never be ignored — can be so important. In this video, Doctor KDM explains how doctors check for blocked arteries in three major areas of the body: the neck and brain, the heart, and the legs. We look at carotid artery disease, coronary artery disease, and peripheral arterial disease in a clear, practical way for the lay public. You will learn why there is no single perfect “whole body artery scan,” why a normal ECG does not always mean your heart arteries are clear, and why leg pain when walking may be a warning sign of circulation problems. ⏱️ TIMESTAMPS: 0:00 - Introduction 1:40 - Neck and brain arteries 2:16 - Stroke and TIA warning symptoms 3:01 - Carotid Doppler ultrasound 4:12 - CT angiogram for neck/brain arteries 4:34 - MR angiogram and brain scans 5:18 - Neck/brain artery takeaway 5:35 - Heart/coronary arteries and angina symptoms 6:19 - Emergency chest pain warning signs 6:30 - ECG, troponin, and risk blood tests 7:13 - Stress tests 7:55 - Coronary calcium score 8:45 - CT coronary angiogram 9:11 - Invasive coronary angiogram 9:36 - Heart artery takeaway 10:08 - Leg arteries and peripheral arterial disease 10:20 - Walking pain/claudication symptoms 10:50 - Other leg artery warning signs 11:19 - ABPI ankle-brachial pressure test 11:57 - Toe pressure and other vascular tests 12:03 - Leg artery duplex ultrasound 12:19 - CT/MR angiography for leg arteries 12:47 - Leg artery takeaway 13:08 - Action plan and risk factors 13:30 - Take symptoms seriously 13:45 - Match the test to the artery system 14:19 - Don’t be falsely reassured by one normal test 14:42 - Prevention and treatment priorities 15:29 - Final takeaway 16:08 - Outro 👨‍⚕️ ABOUT ME: UK-based Consultant Physician with 15+ years of frontline hospital experience, Board-Certified in Internal Medicine.
