2. Calcification - Wikipedia

   en.wikipedia.org/wiki/Calcification

   One of the principal causes of arterial stiffening with age is vascular calcification. Vascular calcification is the deposition of mineral in the form of calcium phosphate salts in the smooth muscle-rich medial layer of large arteries including the aorta. DNA damage, especially oxidative DNA damage, causes accelerated vascular calcification. [11]

3. BaleDoneen method - Wikipedia

   en.wikipedia.org/wiki/BaleDoneen_Method

   [5] The method also uses the coronary artery calcium score (CAC), [5] a measurement of the amount of calcium in the walls of the arteries that supply the heart muscle, using a coronary CT calcium scan of the heart. [6] [7] CAC has been shown to be an independent marker of risk for cardiac events, cardiac mortality, and all-cause mortality. [8]

4. Coronary CT calcium scan - Wikipedia

   en.wikipedia.org/wiki/Coronary_CT_calcium_scan

   A coronary CT calcium scan is a computed tomography (CT) scan of the heart for the assessment of severity of coronary artery disease. Specifically, it looks for calcium deposits in atherosclerotic plaques in the coronary arteries that can narrow arteries and increase the risk of heart attack. [ 1 ]

5. Troponin - Wikipedia

   en.wikipedia.org/wiki/Troponin

   When the muscle cell is stimulated to contract by an action potential, calcium channels open in the sarcoplasmic membrane and release calcium into the sarcoplasm. Some of this calcium attaches to troponin, which causes it to change shape, exposing binding sites for myosin (active sites) on the actin filaments .

7. T-tubule - Wikipedia

   en.wikipedia.org/wiki/T-tubule

   T-tubules (transverse tubules) are extensions of the cell membrane that penetrate into the center of skeletal and cardiac muscle cells.With membranes that contain large concentrations of ion channels, transporters, and pumps, T-tubules permit rapid transmission of the action potential into the cell, and also play an important role in regulating cellular calcium concentration.

8. 8 Common Cardiovascular Diseases for Men & How to Prevent Them

   Dilated cardiomyopathy is when the muscle walls of your heart become stretched and can’t pump blood properly. It can be caused by inherited genes, chronic conditions, and unhealthy lifestyle habits.

9. Myocardial contractility - Wikipedia

   en.wikipedia.org/wiki/Myocardial_contractility

   Increase the amount of calcium in the sarcoplasm. More calcium available for Troponin to use will increase the force developed. Decreasing contractility is done primarily by decreasing the influx of calcium or maintaining lower calcium levels in the cytosol of cardiac myocytes during an action potential.
