WebA coronary angiogram is a test that uses X-rays to show how well your blood is moving in your heart’s arteries ( coronary arteries ), and to look for clogs in them. Your coronary arteries are important because they get blood to your heart’s muscle. A blocked coronary artery can lead to a heart attack, which is when heart muscle dies. WebNov 7, 2000 · Background—Coronary blood flow occurs mainly during the diastolic phase of each cardiac cycle and is mainly dependent on diastolic driving pressure, especially in the left anterior descending coronary artery (LAD).We hypothesized that calculation of the ratio of the diastolic driving pressure of a stenotic LAD to its normal value, namely diastolic … The decision to perform a percutaneous coronary intervention (PCI) is usually based on angiographic results alone. Angiography can be used for the visual evaluation of the inner diameter of a vessel. In ischemic heart disease, deciding which narrowing is the culprit lesion is not always clear-cut. Fractional flow reserve can provide a functional evaluation by measuring the pressure decline caused by a vessel narrowing. toc in obsidian
