Patients should be asked about chest pain, its relation to physical activity, and radiation of the pain into the jaw, neck, left arm, or into the back. CAD is normally the result of atherosclerosis, the build-up of plaque due to damaged endothelium that allows fat to accumulate and decrease the diameter of the vessel. The diagnosis of MINOCA is dependent on the presence of clinical acute MI and the absence of obstructive coronary disease. Traditionally, CMD has been classified according to the clinical setting in which it may occur. If a patient with high pre-test probability has a … The cause depends on the type of coronary heart disease. Many people have both obstructive and nonobstructive forms of this disease. Pathophysiology of Coronary Artery Disease. Up to 75% of individuals with heart failure have a history of hypertension. Coronary artery disease occurs when atherosclerosis affects the coronary arteries that deliver blood flow to the myocardium. What is Coronary Artery Disease? Because of considerable heterogeneity of coronary vasculature, what is considered atypical, abnormal, aberrant, anomalous, accessory, ectopic, incidental, variant, or significant is often unclear. Coronary artery disease pathophysiology revolves around a few theories.

We review here how these advances have altered our concepts of and clinical approaches to both the chronic and acute phases of CAD. Viewpoints on the pathophysiology of coronary atherosclerosis have dramatically changed in the last few years. However, its ability to diagnose hemodynamically significant lesions is limited [5]. A patient with low pre-test probability and an initially slightly elevated cTn that remains stable on repeat testing probably has non-ACS cardiac disease (eg, heart failure, stable coronary artery disease). Coronary artery disease could manifest as stable ischemic heart disease (SIHD) or acute coronary syndrome (ACS). Br Heart J. About 20% of this plaque volume contains calcium which is measurable on CAT scan, providing a marker for the total plaque … The risk of any subject with coronary artery disease having a future acute event will depend on the number of these vulnerable plaques which are present rather than on the total number of plaques. CAD is usually caused by cholesterol deposits called plaques that cause inflammation and narrowing of the coronary arteries. Normally, blood flows through blood vessels like water through a hose.
