New Exercise Parameter for the Identification of Severe Coronary Artery Disease: Conclusion

The case we have described here illustrates the clinical usefulness of f SBP-RR in the diagnosis of severe coronary artery disease in patients receiving antianginal therapy. As shown in Figure 2, the patients 12-lead electrocardiographic recordings during peak exercise and recovery period failed to reveal diagnostic ST segment changes, and the patient did not experience […]

New Exercise Parameter for the Identification of Severe Coronary Artery Disease: Outcome

Crawford et al demonstrated that an abnormal SBP-RR (defined as a SBP-RR >1.0, >0.9, >0.8 at respectively 1, 2, and 3 minutes in the recovery period) is equal in sensitivity to exercise thallium 201 scintigraphy in detecting single vessel disease. Finally, Mohan and Wasir observed that after coronary artery bypass surgery, the SBP-RR returned back […]

New Exercise Parameter for the Identification of Severe Coronary Artery Disease: Discussion

The heart was tomographically imaged under an orbitor gamma scintillation camera within 10 minutes after exercise and three hours later to obtain the redistribution images. The thallium 201 scintigrams revealed reversible filling defects indicative of ischemia in the anterior, inferior, and septal regions of the heart (Fig 3). Discussion This case demonstrates the usefulness of […]

New Exercise Parameter for the Identification of Severe Coronary Artery Disease: Case Report

Case Report The patient is a 60-year-old white man with a history of insulin-dependent diabetes mellitus, hypertension, and two prior non-q-wave myocardial infarctions. The patient also has exertional angina usually relieved by rest and sublingual nitroglycerin. Cardiac catheterization had revealed significant three-vessel coronary artery disease; mid-left circumflex artery lesion (80 percent), proximal right coronary artery […]

New Exercise Parameter for the Identification of Severe Coronary Artery Disease

Exercise testing remains one of the most useful ┬ánoninvasive diagnostic tests for identification of the patient with coronary artery disease. Significant ST segment depression, chronotropic incompetence,┬áhypotensive systolic blood pressure response, and angina at low workload have all been shown to be of diagnostic and prognostic value in patients with severe coronary artery disease. However, the […]
