Understanding Arterial Calcification: Impacts on Heart Health
Written on
Chapter 1: The Role of Arterial Calcification
Arterial calcification significantly influences the formation of atherosclerotic plaques, exacerbating heart disease complications. This condition accelerates the overall progression of cardiovascular issues.
The coronary artery calcification (CAC) score is crucial for evaluating heart disease patients. This score indicates calcium accumulation in the plaque within the coronary arteries, which supply essential blood to the heart muscle. The presence of calcium may serve as an early indicator of coronary artery disease, potentially leading to heart attacks.
To grasp how our arteries can become calcified, we can draw a parallel to fouling in pipes.
Section 1.1: Understanding Fouling in Pipes
Pipes, hollow cylindrical structures, transport fluids across various applications—from supplying drinking water to removing wastewater. In industrial contexts, such as Nigeria's crude oil pipelines, these systems face vulnerabilities like sabotage and theft.
As a former chemical engineering student, I found mastering fluid mechanics to be quite challenging. Now, I have the task of imparting this knowledge to my students, which is equally daunting.
Biologically, our bodies also feature pipes—arteries carry oxygen-rich blood throughout, while veins return oxygen-poor blood to the lungs for replenishment.
Fouling, a term commonly used in technical fields, refers to the unintended buildup of deposits on surfaces. This phenomenon occurs in pipes, machinery, and heat exchangers, resulting from dissolved substances in liquids or external solids entering a system.
Subsection 1.1.1: The Impact of Calcium Carbonate
Calcium carbonate is a major contributor to fouling, particularly in water systems. The presence of hard water, rich in dissolved calcium carbonate, can lead to solid precipitation, forming scale on surfaces—a common issue known as scaling.
We must be vigilant about fouling because calcium carbonate and calcium phosphate are primary components of our bone minerals.
Imagine the osteoclast cells in our bones working excessively to convert bone minerals into soluble calcium for absorption back into the bloodstream.
Section 1.2: Misconceptions About Osteoporosis
Osteoporosis is often oversimplified as merely a lack of dietary calcium, but the reality is more complex.
The connection between calcium intake and bone health is crucial, especially if one consumes calcium carbonate supplements—often the cheapest option available—without adequate Vitamin K2.
Chapter 2: The Consequences of Inorganic Calcium Fouling
The inorganic calcium fouling can lead to further biofouling. Precipitated calcium deposits on pipe walls increase surface roughness, providing more area for biological microorganisms to adhere and form biofilms—known as biofouling.
Biofouling refers to the accumulation of biological organisms, similar to the bathroom slime that forms in toilets.
A collection of biological slime is termed a biofilm, which can also develop in areas like water meters, where it poses no harm. My former colleague even conducted her Ph.D. research on these biofilms!
As calcium carbonate scales build up inside pipes, the roughness of these walls increases. The difference between a smooth metallic surface and one covered in calcium deposits is easily noticeable; the latter appears white and feels rough to the touch.
As arteries accumulate calcium deposits, they too become more hospitable environments for biological organisms to settle, particularly foam cells, which are living entities in their own right.
The first video, "Coronary Artery Calcification: When Artery Becomes Bone," explores the implications of calcification on arterial health.
The second video, "Coronary Artery Calcification November 8 2019," provides insights into recent findings on coronary artery calcification and its health effects.
To prevent calcium in our blood from precipitating in our arteries, we must ensure it remains dissolved and transported to our bones for mineral formation. We certainly do not want our arteries resembling a mix of bone and artery, which is indicated by our CAC scores.
While our bodies can clear arterial deposits through a process known as efferocytosis, achieving this requires a dedicated lifestyle and discipline—challenges many of us face today.
