Progressive Coronary Artery Calcium Buildup






 What this tells us is that measuring the change in calcium buildup just happens to be a strong predictor of heart disease. This can be independent of other symptoms. In fact it would be beneficial to have a way to even determine that progression throughout life.

It says nothing about cause and effect and we certainly have seen plenty of speculation. The nanobacteria concept was at least somewhat convincing. The fact remains that the calcium must crystallize and that remains unclear. It certainly will not be because there is any actual imbalance in the blood unless some other part of the system is imbalanced.

Large micro crystals will surely stimulate inflammation and plausibly produce the remaining effects. For that reason understanding what is happening here happens to be important and has already spawned a range of related therapies.

Question? Is it driven by vitamin C or vitamin D deficiency?



Increased Risk of Heart Attack and Death With Progressive Coronary Artery Calcium Buildup


May 2, 2013 — Patients with increasing accumulations of coronary artery calcium were more than six times more likely to suffer from a heart attack or die from heart disease than patients who didn't have increasing accumulations, according to a recent study published in the Journal of the American College of Cardiology.

The study, conducted at Los Angeles Biomedical Research Institute (LA BioMed) and five other sites, suggests more frequent monitoring of patients with coronary artery calcium accumulations could help determine the risk of heart attacks and give those patients time to make changes to reduce the risk.

For the study, researchers measured the coronary artery calcium in a diverse group of 6,778 persons aged 45 to 84 years from the MESA (Multi-Ethnic Study of Atherosclerosis) study. The participants had no history of coronary heart disease prior to enrolling the MESA study.

Researchers found that nearly half (49.9%) of the participants had coronary artery calcium in their initial scans -- and most of them (84.8%) continued to accumulate coronary artery calcium, as measured in subsequent CT (computed tomography) scans approximately 2.5 years later. For those with the greatest increase in coronary artery calcium buildup (300 units or more), the study found a more than six-fold increase in coronary heart disease incidents independent of other risk factors for heart disease.

"We have known that coronary artery calcium can be related to heart disease, but this study shows the progression of the accumulation of the calcium in the arteries can be a significant factor in evaluating the risk that a patient may suffer a heart attack in the future," said Matthew Budoff, MD, the primary author of the study and an LA BioMed principal investigator and director of Cardiac CT. "By conducting serial CT scans, we may be able to identify people at high risk of a heart attack and intervene to prevent that heart attack through new therapies, lifestyle changes and other modifications. Further study is needed to determine if more frequent CT scans would be a cost-effective approach to reducing coronary heart disease, the No. 1 cause of death for both men and women in the U.S."

About 600,000 people in the U.S. die of heart disease every year, and coronary heart disease costs the country nearly $109 billion annually, according the Centers for Disease Control and Prevention.

CT scans can look for specks of calcium, or calcifications, in the walls of the coronary arteries to detect early signs of coronary heart disease, which is caused by the buildup of plaque, a waxy substance in the coronary arteries. Coronary heart disease can lead to heart attacks, heart failure and arrhythmias, which are problems with the rate or rhythm of the heart.
