A man and his 40, complaining of pain in the chest, the doctor and the family. He had no known heart disease; It is a few pounds, sitting behind a desk all day. What is the chance to die within 10 years of coronary event next? Coronary CT Angiography (CCTA), a new, non-intrusive way, offers a fast and reliable for ruling out the presence of relevant arterial stenoses.
"5.5% (9 million) Americans aged 20 to 79 years of intermediate risk of death or serious heart heart attack 10 years, using standard NCEP definition of moderate risk-two or more risk factors with Framingham score of 10%-20%" according to Jon g Keevil., M.d., Department of medicine at the University of Wisconsin, Madison. "By setting the most liberal of all-not even bothering to count the risk factors, and instead tag them all with Framingham score of 6% to 20% as medium risk-so 16.2%," says Dr. Keevil.
Identifying and treating coronary (CAD) in the early stages of his has a positive effect on the health of the patients and is cheaper than the far-advanced treatment of vascular diseases.
One of the traditional test for determining the presence and severity of myocardial perfusion Imaging is CAD (MPI), which will indirectly block the arteries. This check is done by using a camera nuclear over up to several hours. Another test is the traditional, invasive imaging angiogram coronary ????????. Normal Angiogram is a small but expensive with the risk of complications, and it clearly requires hospitalization or a period of observation for a few hours after the procedure. According to Dr. Armin Zadeh, Director of from Johns Hopkins University School of medicine, "complication statistical diagnostic catheterization die is 1 in 1,000. There is still a 1 in 500 of the lines. The rate of cardiovascular complication is quite extreme. "
CCTA 20 minutes less patient than risk showing angiography invasive; Amin ruled out the presence of CAD patients for low to moderate to significant probability of CAD; And reliably achieve a high level of technical performance and diagnostic accuracy need to replace conventional angiography. Coronary CT angiography is also a useful alternative and clearer MPI, about the same level of exposure to radiation.
Coronary CT angiography using a CAT scanner, combined with the iodine-based contrast agents, to create a cross section views between heart hchliliim. Workstation advanced 3D rendering is obtained, to describe anatomy. Radiologist or crdiolog evaluates the rendered images and reports his or her findings.
But not all patients with chest pain has a coronary.
The article was brdiologia today, Dr. David Dowe, MD and imaging COO of the Atlantic Ocean, is written, "... Primary care physicians like that study (CCTA) telling them exactly where the patient stands with coronary. Essentially he meets the question, whether the patient has coronary or not? There will be many times already repaired by Sandy Cardiology when in fact they have walked right into their chest pains gastroenterologist that initially the esophagus. "
Coronary CTA helps hospitals and primary care physician's place in the hands of the appropriate specialist without the patient having to see crdiolog, pulmonologist and gastroenterologist. The advantage of avoiding unnecessary checks is sick, potentially dangerous and costs related to their htrgzoioth.
Finally, with the ability of CT Imaging of the heart as part of a larger scan, the scan of the chest CCTA multiplies a built-in, tumors, aneurysms and variances and other embolisms doom-that can be recognized.
