The life-threatening sign is called


The American scientists found out that the high level of calcium in coronary arteries is in the middle age connected with serious heart failure in the future. It is reported in the press release on EurekAlert!.

In a research took part 2449 people in young and middle age. By means of tomographic scanning experts estimated a condition of blood vessels of volunteers, including the level of accumulation in coronary arteries of calcific plaques. These plaques contain not only calcium, but also fat and cholesterol therefore the increased keeping of the last in blood promotes narrowing of vessels and reduction of a blood-groove.

the Indicator of accumulation of plaques (SAS) was estimated on 15th and 25th researches when average age of participants already reached 50 years. At the same time in a decade the share of volunteers with zero SAS decreased by five percent. Increase in level of calcific plaques correlated with age, increase in systolic arterial blood pressure, cholesterol content, presence of diabetes and smoking.

Besides, turned out that at high SAS the thickening and increase in the sizes of the left ventricle regardless of other factors is observed. Such changes lead to the fact that heart is forced to work more intensively to pump blood, and the risk of life-threatening heart failure increases.
