This data convinced the American College of Cardiology (ACC) to include CT calcium scoring in its revised guidelines for prevention and cholesterol released last fall. In addition, the ACC highlighted the evidence for CT calcium scoring as a late breaking session at its 63rd Annual Scientific Session in March.CT calcium scoring is a test that measures the amount and pattern of calcium that has accumulated in a patient’s coronary arteries. The test has been available for decades, but doctors and scientists debate whether and how it should be used to improve patient care.  Video Player is loading.GE Cardiographe cardiac CT scanner at SCCT19Play VideoPlayMuteCurrent Time 0:00/Duration 0:38Loaded: 26.15%Stream Type LIVESeek to live, currently playing liveLIVERemaining Time -0:38 Playback Rate1xChaptersChaptersDescriptionsdescriptions off, selectedCaptionscaptions settings, opens captions settings dialogcaptions off, selectedAudio Trackdefault, selectedFullscreenThis is a modal window.Beginning of dialog window.

There is mounting data showing CT coronary calcium scoring helps predict the risk level of cardiac patients. Mounting Evidence for Calcium ScoringThe new calcium scoring studies presented at ACC earlier this year, some of which tracked patients for 10 years or more, show calcium scans to be better at predicting long-term heart problems than other available tests, particularly when evaluating low-risk patients. “We made it into the primary ACC guidelines, which is a nice pat on the back for coronary calcium scoring,” said Matthew Budoff, M.D., FACC, professor of medicine, cardiology, Los Angeles Biomedical Research Institute, David Geffen School of Medicine, and a past-president of the Society of Cardiac CT (SCCT). “I also think it is very promising that cardiac CT has made the late breaking trials for the past several ACC meetings.”  A Long-term Complement to Detecting Heart DiseaseA meta-analysis of 17 studies conducted by a research team from Mount Sinai St. Luke’s-Roosevelt Hospital Center in New York found a rough, though not perfect, correlation between coronary calcium scores and the results of a common test used to detect coronary heart disease known as SPECT-MPI, which uses single-photon CT scanning to provide a 3-D image of the heart. The analysis revealed that calcium scores of zero generally are associated with negative SPECT-MPI tests for coronary heart disease, while calcium scores above 400 are generally associated with abnormal SPECT-MPI results. The frequency of ischemia rose with an increasing calcium score. Because the tests reflect different aspects of heart health, the two can be complementary, with coronary calcium scans offering valuable insights about long-term heart disease risk and SPECT-MPI offering a clearer picture of the short-term risk of an adverse cardiac event, said lead study author Chirag Bavishi, M.D., MPH.  Siemens Go.Top CT scanner at SCCT19Video Player is loading.Play VideoPlayMuteCurrent Time 0:00/Duration 1:05Loaded: 15.14%Stream Type LIVESeek to live, currently playing liveLIVERemaining Time -1:05 Playback Rate1xChaptersChaptersDescriptionsdescriptions off, selectedCaptionscaptions settings, opens captions settings dialogcaptions off, selectedAudio Trackdefault, selectedFullscreenThis is a modal window.Beginning of dialog window.

Dose ReductionOne of the biggest issues preventing expansion of cardiac CT over the past decade has been the significant levels of patient radiation exposure. However, Budoff said new iterative and model-based image reconstruction software and new X-ray tube and detector technology has slashed the radiation dose.

The advantages of calcium scoring were especially prominent in the approximately 80 percent of participating patients considered to be at low risk for heart disease based on their treadmill test results. Lead study author Su Min Chang, M.D., said the results show that calcium scoring can help catch patients who are on the way to developing heart disease earlier than other available tests. Related Content Feature | May 28, 2014 | Dave Fornell CT Coronary Calcium Scoring Predicts Long-term Cardiac Health New studies at ACC.14 bolster evidence for coronary artery calcium scans as assessment tool The ACC 2014 late-breaking trials included the following: Budoff said the new guidelines, released in November 2013, call for the use of calcium scoring to help stratify risk in patients to help identify patients that might require more aggressive treatments.  A Reflection of Overall Heart HealthCalcification in the coronary arteries is a common manifestation of unhealthy vascular aging and serves as a good predictor of poor cardiovascular outcomes. In contrast, a finding of a coronary artery calcium score of zero in a middle age or older adult is a sign of healthy aging and a good predictor of longevity. In a study of 1,850 participants from the Multi-Ethnic Study of Atherosclerosis (MESA), researchers at the Johns Hopkins Ciccarone Center for the Prevention of Heart Disease showed that no single risk factor predicted which individuals would maintain a coronary artery calcium score of zero over a 10-year period. Analyzing demographic and lifestyle risk factors of study participants who had a calcium score of zero at the start of the study, they found that younger participants and those without multiple traditional cardiovascular risk factors were more likely to maintain a score of zero during a second scan taken 10 years later. Lead author Seamus Whelton, M.D., said the study shows that healthy arterial aging appears to be influenced predominantly by the long-term maintenance of a healthy lifestyle rather than any one specific risk factor.  Videos | CT Angiography (CTA) | August 07, 2019 VIDEO: Walk Around of a GE Cardiographe Dedicated Cardiac CT Scanner This is a quick walk around of the GE Healthcare Cardiographe dedicated cardiac CT system on display at the… read more He said these anatomical views can be scanned in minutes, instead of sending a patient for an invasive diagnostic angiogram in the cath lab.

CT AngiographyThe use of coronary CT angiography (CCTA) has been growing rapidly over the past few years because of its noninvasive nature, ease of use and access as more hospitals install 64 or higher slice CT systems, and as evidence of its clinical utility continues to be positive. Budoff said the ACC late-breaking sessions have included CCTA trials for the past several years, highlighting the advances in the technology. CTA creates a dataset, which can be manipulated in advanced visualization software to create 3-D images of the cardiac anatomy and 2-D images of on any imaging plane. Budoff said this is increasing being used to plan more complex interventional and hybrid transcatheter procedures, including transcatheter aortic valve replacements (TAVR). He said TAVR guidelines now require CTA scans for procedural planning and periprocedural image guidance.  Sponsored Content | Case Study | Radiation Dose Management | August 13, 2019 The Challenge of Pediatric Radiation Dose Management Radiation dose management is central to child patient safety.

The vendors have really stepped up to the plate to reduce the amount of dose.” Coronary calcium indicates the extent to which plaque has accumulated and hardened in the heart’s main arteries and is an early sign of coronary heart disease, the number one cause of death for both men and women in the United States. Although the calcium itself is not dangerous, it contributes to the hardening of the arteries and its presence and pattern of accumulation reflects other conditions, such as narrowing of the arteries or an increased risk of dangerous blood clots, which can lead to heart attacks and impaired heart function.

The CT scanner might not come with protocols that are adequate for each hospital situation, so at Phoenix Children’s Hospital they designed their own protocols, said Dianna Bardo, M.D., director of body MR and co-director of the 3D Innovation Lab at Phoenix Children’s. Twenty Years of Data Help Refine Assessments of Low-risk PatientsA 20-year study of nearly 5,600 people offers new insights about the relative mortality risk of patients with no, low, moderate and high calcium scores who are otherwise considered to be at low risk for heart disease. Over an average follow-up period of 10 years, researchers at Los Angeles BioMed at Harbour UCLA Medical Center found that even patients with low calcium scores (1-99) were 50 percent more likely to die than patients with a calcium score of zero. Moderate scores (100-399) were associated with an 80 percent greater likelihood of dying and high scores (above 400) were associated with a three times greater risk of dying as compared to patients with zero calcium. Lead study authors Rine Nakanishi, M.D., Ph.D., and Budoff said the results bolster the case for calcium scoring as a method to refine assessments of a person’s risk for heart disease and identify those who are most likely to benefit from treatment.  A Powerful Indicator of the Risk of Heart Attack A study conducted at Israel’s Lady Davis Carmel Medical Center found coronary calcium scoring to be superior to other CT-based measures of a person’s heart health. Researchers tracked the long-term (eight-year) likelihood of death or heart attack among 620 patients who were referred for CT scanning after experiencing chest pain but who had not been previously diagnosed with coronary artery disease. Comparing three measurements taken during the scans: coronary calcium score, atheroma and luminal stenosis, the researchers found coronary calcium score to be the only independent CT predictor of death or heart attacks long-term after adjusting for clinical risk. Ronen Rubinshtein, M.D., lead study author, said the results suggest coronary calcium is a useful predictor of long-term health outcomes in patients with chest pain because it likely reflects the risk of both plaque accumulation and disease duration and activity, unlike other metrics tested in the study.last_img read more
