10 papers analyzed
Some studies suggest that atherosclerosis, or hardening of the arteries, develops due to factors like smoking, diabetes, high blood pressure, and high cholesterol, while other studies indicate it can be managed or even reversed through lifestyle changes, medications, and regulating bone-forming cells.

Hardening of the Heart: A Dual Perspective
Theological Perspective on Hardening of the Heart
Hardening of the Heart in Religious Texts
The concept of "hardening of the heart" is prominently featured in religious texts, often symbolizing a deliberate rejection of divine messages. In Mark 3:1-6, the hardening of the Jewish religious leaders' hearts is depicted as a sign of their continued unbelief and rejection of Jesus' teachings. This hardening is not merely a lack of understanding but an intentional refusal to accept the message, akin to the hardening of Pharaoh's heart in the Exodus narrative. Theological interpretations suggest that this hardening leads to divine judgment, as seen in the plagues of Egypt and the eventual catastrophe at the Red Sea.
The Intensity Structure of Pharaoh's Heart Hardening
The story of Pharaoh's heart hardening in the Exodus narrative has been subject to various interpretations. One approach suggests an "Intensity Structure," where the LORD's actions against Pharaoh's heart were gradual, starting with a peaceful message and escalating in severity as Pharaoh's obstinacy increased. This interpretation posits that the LORD did not directly harden Pharaoh's heart but responded to Pharaoh's increasing resistance with greater force, ultimately leading to Pharaoh's downfall.
Medical Perspective on Hardening of the Heart
Atherosclerosis: The Biological Hardening of the Heart
In medical terms, "hardening of the heart" often refers to atherosclerosis, a condition characterized by the buildup of plaques in the arteries. These plaques, composed of fat, cholesterol, and calcium, cause the arteries to become narrow and stiff, obstructing blood flow and leading to heart disease. This process is similar to bone formation, involving a balance between bone-forming cells (osteoblasts) and bone-destroying cells (osteoclasts).
Risk Factors and Consequences of Atherosclerosis
Atherosclerosis is influenced by several risk factors, including smoking, diabetes, high blood pressure, high cholesterol, and a sedentary lifestyle. The stiffening of arteries, known as arteriosclerosis, impairs the elasticity of blood vessels, reducing their ability to maintain smooth blood flow and leading to conditions such as diastolic heart failure and cognitive decline. The increased pulse wave velocity in stiffened arteries is a marker of this condition and is associated with higher risks of heart attack and stroke.
Calcium's Role in Arterial Hardening
Calcium plays a significant role in the formation of arterial plaques. The accumulation of calcium in the arterial walls resembles the process of bone formation, contributing to the stiffness and narrowing of the arteries. This calcification is a critical factor in the development of atherosclerosis and its associated complications, such as heart attacks and strokes.
Conclusion
The concept of "hardening of the heart" spans both theological and medical domains, symbolizing spiritual obstinacy in religious texts and a literal stiffening of arteries in medical science. In theology, it represents a deliberate rejection of divine messages, leading to judgment, while in medicine, it denotes a pathological condition resulting from plaque buildup in arteries, leading to severe cardiovascular diseases. Understanding both perspectives provides a comprehensive view of this multifaceted concept.
