Nuclear ventriculography: This uses tracers, or radioactive materials, to create an image of the heart chambers. Each modality has specific criteria for an abnormal test.
Thus, for application of the exercise ECG, there cannot be a requirement for involvement of greater than or equal to two coronary artery territories for further discussion, refer to the following paragraph, as well as to item 3 in the section on concluding concepts and Recommendation Coronary angiography is most often performed following an abnormal stress test or in the setting of an acute coronary syndrome unstable angina or heart attack in individuals who are candidates for revascularization either by PCI or CABG.
EECP was shown to increase the time to ST-segment depression during exercise testing, reduce angina, and improve health-related quality of life for at least 1 year in a randomized, double-blind study of patients with chronic stable angina Soran et al.
MRI machines use a powerful magnetic field, radio waves and a computer to produce detailed images. If there are areas with decreased blood flow, this could indicate plaque with blood vessel narrowing.
Chronic high-grade narrowing of the coronary arteries can induce transient ischemia which leads to the induction of a ventricular arrhythmiawhich may terminate into a dangerous heart rhythm known as ventricular fibrillationwhich often leads to death. However, most reports in patient records do not provide these descriptors, but rather they simply categorize the exercise ECG as being normal or abnormal, positive or negative.
CT scans: These help the doctor visualize the arteries, detect calcium within fatty deposits, and characterize any heart anomalies. Medications that people can take to reduce the risk or impact of CHD include: Beta-blockers: A doctor may prescribe beta-blockers to reduce blood pressure and heart rate, especially among people who have already had a heart attack.
Angina is classified using the Canadian Cardiovascular Society CCS scheme, which grades angina or an anginal equivalent e. Ranolazine increases exercise tolerance in patients with stable angina, reduces episodes of recurrent ischemia, and provides additional antianginal benefit in patients who are already on intensive antianginal therapy with beta-blockers and CCBs.
