In the study, called Coronary Artery Risk Development in Young Adults (CARDIA), the researchers looked at 495 men and women who were 35 to 47 years old and free
of coronary artery calcification in 2000 or 2001.
Their findings, published in the journal Atherosclerosis, showed a statistically significant inverse association of both the number of HDL particles (HDL - P) and the concentration of small and medium - sized HDL particles (MS - HDL - P)
with coronary artery calcification, after adjusting for age, statin use, smoking, and other factors.
The assessed risk of more than 65 % of patients without established cardiovascular disease who were evaluated for
coronary artery calcification via ungated chest CT was reclassified after undergoing Agatston - scored ungated CT scans, according to new research conducted at Mount Sinai Medical Center.
«Agatston scoring of
coronary artery calcification on routine ungated chest CT has the potential to spare many patients from unnecessary statin therapy,» said principal investigator Michael Kadoch.
«Our findings indicate that HDL - P and MS - HDL - P are better independent markers of coronary artery disease, as reflected
by coronary artery calcification, than HDL - C, at least in this bi-ethnic population of Israelis and Palestinians,» said Dr. Chobufo Ditah.
To study this concept, researchers evaluated the association between dietary intake of fruits and vegetables in young adults and the presence
of coronary artery calcification (CAC) 20 years later.
In women, aortic calcification appears earlier than
coronary artery calcification, and thus may be a more sensitive indicator of subclinical cardiovascular disease than coronary artery calcification.25 However, a previous Dutch study26 found no significant association between coronary calcification and whether a woman had ever compared with never breastfed.
They were four times more likely to have
coronary artery calcification.
There also was no independent association of MCI and intima media thickness (IMT) or
coronary artery calcification (CAC), two other surrogate markers of cardiovascular risk.
With these data in hand, they looked for associations between the concentrations and sizes of different HDL particles, and
coronary artery calcification.
One extra hour of sleep per night appears to decrease the risk of
coronary artery calcification, an early step down the path to cardiovascular disease, a research team based at the University of Chicago Medical Center reports in the Dec. 24/31 issue of JAMA.
This time they looked at the connections between sleep duration and
coronary artery calcification.
The Relationship Between Absence
Coronary Artery Calcification and Myocardial Perfusion Single Photon Emission Computed Tomography Coronary artery calcification score (CACS) is well validated prognostic tool in coronary artery disease (CAD).
In fact, an extra hour of sleep each night was associated with a 33 % lower chance of
coronary artery calcification, a reduction in heart risk that's on par with having about a 16 - point drop in systolic blood pressure, according to a study published in Wednesday's issue of the Journal of the American Medical Association.
The researchers found that 32 percent of the women who had not breast - fed had
coronary artery calcification, compared with 17 percent of the breast - feeding moms.
