— Written By Sarah Lewis, PharmDUpdated on September 15, 2021 What is a coronary calcium scan? A coronary calcium scan is a type of CT (computed tomography) scan. CT scans are diagnostic medical imaging exams. They are not invasive and use X-rays and a computer to make cross-sectional images of the body. A coronary calcium scan makes pictures of the coronary arteries—the arteries that supply blood to the heart muscle. The images can show the amount of calcified plaque buildup inside the coronary arteries; plaque buildup is a sign of atherosclerosis. Other names for the test include CT coronary calcium scan, coronary calcium heart scan, calcium scan of the heart, and calcium scan test. Doctors generate a coronary artery calcium score from the scan. Why is a coronary calcium scan performed? A coronary calcium scan can help your doctor determine your risk of atherosclerotic heart disease, heart attack, and stroke. The test looks for calcium in the walls of the coronary arteries. The presence of calcium is a good indication of plaque buildup—the cause of atherosclerosis and coronary artery disease (CAD). Plaque is a waxy substance containing cholesterol and other substances. Calcium in plaque hardens it. Plaque buildup and CAD make serious health events, such as heart attack and stroke, more likely.A coronary calcium scan isn’t for everyone. Your doctor may only recommend a coronary calcium scan if your heart health risk is uncertain.Current guidelines, without the scan, use a formula to classify your risk of future heart disease. Your

The HeartFlow® analysis is the first and only non-invasive test used to diagnose coronary artery disease (CAD). This cardiac test produces a personalized 3D model with exceptional visualization of the coronary arteries and enables physicians to develop effective treatment plans, unique to each patient. Historically, this detailed information was only available through an invasive heart procedure. The information gathered from the test, including how a blockage impacts the flow of blood to the heart, can help your doctor develop your customized treatment.What is Coronary Artery Disease?Coronary artery disease (CAD) is the leading cause of death of men and women in the United States. CAD can develop when arteries that lead to the heart narrow or become blocked – reducing blood flow to the heart. When this occurs, chest pain, heart attacks and death can result.Who is a candidate for a HeartFlow Analysis?If your doctor needs more information after a CT scan of the heart, he or she may order a HeartFlow Analysis. This test can be performed in the same clinic visit as your CT scan. There is not additional risk from the test.What to expect during a HeartFlow Analysis?HeartFlow technology will use the CT scan results to create a personalized digital 3D model of your coronary arteries. The analysis will calculate how much your blockages limit your blood flow in the heart.Your cardiologist will receive the digital, color-coded 3D model of your arteries and will use it to develop a customized treatment plan for you.Benefits of HeartFlow Analysis:Provides a

A worried patient who had often been told “nothing was wrong in your heart,” and prevent the blind empirical use of antianginals with side-effects such as hypotension or bradycardia.In summary, invasive testing for coronary vasospasm is part of a comprehensive assessment of INOCA and MINOCA, with the aims of achieving symptom relief and improving the quality of life and prognosis in these patients. Clinical PerspectiveCoronary vasospasm can be evaluated only through invasive studies with reliable accuracy.The most commonly used provocation agent in the invasive coronary artery spasm assessment is acetylcholine.Multiple protocols for acetylcholine use are available; practical and commonly used protocols are discussed in this paper.Unified protocols and results interpretation are paramount to accurate diagnosis and a standardized approach to treatment in vasospastic angina.
