Understanding the Role of Stents in Managing Blocked Arteries
Written on
Chapter 1: The Functionality of Stents
Stents play a crucial role in maintaining blood flow through arteries that have been narrowed or blocked. While they are effective in propelling blood circulation, it's important to note that arteries can still become obstructed again over time.
According to the World Health Organization, cardiovascular diseases are the leading cause of death globally. This has led to the healthcare industry evolving into a significant financial venture, ostensibly aimed at extending human life.
Numerous opportunities arise from the issue of heart disease, such as:
- The prescription of statins, which over 35 million Americans take daily.
- The deployment of stents, small tubes inserted into arteries to keep them open.
- The use of bypass surgery, redirecting blood flow around blocked arteries.
Despite these interventions, there is no assurance that stents, bypass surgeries, or medications like statins will prevent future heart attacks. A Reuters article indicates that previous studies have found no significant reduction in heart attack risk or mortality when combining invasive procedures with medical treatment, compared to non-invasive methods alone.
This presents a dilemma: individuals may seek costly surgeries for heart disease, only to discover they do not effectively reverse the condition.
Johns Hopkins Medicine states that nearly all angioplasty procedures now involve the use of coronary stents. These stents are small, expandable metal mesh coils placed within newly opened arteries to prevent them from narrowing again. Over time, tissue grows around the stent, coating it like a second skin, typically completing this process in 3 to 12 months, depending on whether the stent is medicated.
As a result, individuals diagnosed with blocked arteries may be advised to undergo surgery where a "tiny, expandable metal mesh coil" is inserted to ensure the artery remains open.
However, Newton's Third Law reminds us that for every action, there's an equal and opposite reaction. The blood flow generates force on the stent, which in turn exerts friction against the blood. This friction could lead to deposits forming on the stent's surface.
Section 1.1: How Arterial Calcification Affects Plaque Build-Up
Calcification can exacerbate the challenges of heart disease by accelerating plaque formation.
Johns Hopkins also cautions that tissue growth on the stent's surface is inevitable, as biological cells tend to accumulate on surfaces. This growth can lead to re-blockage of the artery.
Subsection 1.1.1: The Analogy of Bathroom Slime
The way our gut microbiome operates is reminiscent of how slime develops in unclean bathrooms. Both processes rely on similar principles of accumulation.
As tissue layers build up on the stent, the risk of artery re-obstruction increases. Thus, maintaining a dynamic equilibrium is vital.
Section 1.2: The Importance of Dynamic Equilibrium in Health
Health requires balancing various dynamic states, as living cells within our bodies are constantly active.
Tissue deposition on a stent parallels the growth of slime, necessitating methods to manage tissue accumulation. Blood thinners can reduce blood viscosity and create turbulence to counteract this.
Ultimately, patients with heart disease who receive stents often face chronic inflammation, which impedes their body's ability to eliminate cells effectively. This is a primary contributor to the buildup of atherosclerotic plaques.
Chapter 2: Limitations of Stents in Heart Disease Management
The first video titled "Coronary Stents: What You Need to Know" discusses the essential information regarding stents, their functions, and what patients should consider.
The second video titled "WHY Heart Stents FAIL?" explores the reasons why stents may not always work as intended, shedding light on the complexities of heart disease treatment.
In conclusion, while stents are designed to keep arteries open and facilitate blood flow, they do not guarantee protection against heart attacks. Blockages can still occur due to tissue accumulation around the stent, and lifestyle choices remain crucial in managing heart health. This biological issue cannot be easily resolved through surgical or medicinal means alone.
