Coronary angiography: a long look at a short queue
Article Abstract:
Patients with coronary artery disease required to wait three weeks or more for diagnostic angiography may be at increased risk for heart attack and death. Although there are many interventional cardiologists in practice, some patients must still wait in a queue for angiography services. It is, as yet, unclear whether patient queuing is the result of overly aggressive referral to cardiologists, failure to refer patients to other medical facilities, or an undersupply of angiography services. Patients with unstable angina or high-risk coronary artery disease should receive appropriate diagnostic care and treatment, regardless of local supply and demand issues among cardiologists.

Queuing for Coronary Angiography During Severe Supply-Demand Mismatch in a US Public Hospital
Article Abstract:
Delayed coronary angiography in patients with suspected coronary artery disease may increase the risk of heart attack and other complications. Researchers monitored 381 patients referred for radiologic examination of their coronary arteries, but required to wait until services became available. Seven percent of the patients required hospitalization, 1% had a heart attack, and 2% died awaiting angiography. Delays longer than two weeks, particularly in patients with very poor stress test results or requiring 2-3 anti-ischemia medications, should be avoided.

Cardiac troponin T and C-reactive protein for predicting prognosis, coronary atherosclerosis, and cardiomyopathy in patients undergoing long-term hemodialysis
Article Abstract:
Hemodialysis patients who have elevated blood levels of cardiac troponin T and C-reactive protein have a higher risk of premature death than other hemodialysis patients, according to a study of 224 patients. In addition, an elevated cardiac troponin T level was a risk factor for coronary artery disease and heart failure. Cardiac troponin T is a protein released by the heart when it is damaged. C-reactive protein is a marker of inflammation.
