Can you exercise if you have blocked arteries?

Can you exercise if you have blocked arteries?. Many people often disregard the pre-workout class warnings that advise consulting a doctor before engaging in strenuous exercise. The prevailing belief is that exercise is universally beneficial for one's health. However, it is crucial to acknowledge that there are certain medical conditions that can render the elevated heart rate experienced during exercise potentially hazardous. Thus, it is imperative to take these warnings seriously and seek medical advice to ensure one's safety before embarking on rigorous physical activities.

Researchers from the Indian Institute of Technology Kharagpur have discovered that an increased heart rate can trigger a stroke in individuals with severely blocked carotid arteries. In contrast, for individuals who are healthy or have mildly blocked arteries, exercise plays a crucial role in promoting and maintaining healthy blood circulation. This study highlights the importance of considering individual health conditions and seeking medical advice to determine the appropriate level of physical activity for optimal cardiovascular health.

Carotid arteries are responsible for supplying blood flow to the facial tissues and the brain. These vital arteries are situated on both sides of the neck. However, when substances like fat, cholesterol, and other particles accumulate within the inner walls of the carotid arteries, they gradually develop into a plaque, causing a narrowing of the artery. This narrowing can impede the smooth flow of blood, potentially leading to various health complications.

The narrowing of the carotid artery due to plaque accumulation is known as stenosis

The narrowing of the carotid artery due to plaque accumulation is known as stenosis. Detecting the early stages of plaque buildup can be quite challenging. However, stenosis poses a significant risk as it restricts the blood flow to the brain. When the brain is deprived of an adequate blood supply, it also lacks the necessary oxygen, leading to a medical emergency known as a stroke. It is crucial to address stenosis promptly to prevent or minimize the occurrence of strokes and their potential long-term consequences.

In individuals without stenosis, an elevated heart rate serves to enhance and stabilize the drag force that blood exerts on the walls of blood vessels, thereby reducing the risk of stenosis. This mechanism helps maintain healthy blood flow and minimizes the chances of plaque buildup in the arteries. However, for individuals who already have stenosis, the benefits of an elevated heart rate may not be as pronounced. In such cases, it is important to consider the specific circumstances and consult with medical professionals to determine the most appropriate course of action for managing stenosis and optimizing cardiovascular health.

This comprehensive investigation

The researchers employed a specialized computational model to replicate blood flow patterns within carotid arteries at three distinct stages of stenosis: no blockage, a mild 30% blockage, and a moderate 50% blockage. They conducted a comparative analysis by examining the impact of two different heart rate scenarios: an exercise-induced heart rate of 140 beats per minute and resting heart rates of 67 and 100 beats per minute, respectively. This comprehensive investigation allowed them to assess how varying degrees of stenosis and heart rates influenced blood flow dynamics, providing valuable insights into the relationship between cardiovascular health and exercise-induced heart rate in individuals with different levels of arterial blockage.

As anticipated, the findings revealed that in the case of healthy individuals and those with mild blockages, the exercise condition had a positive impact on the simulated carotid artery's health. However, the outcomes for individuals with moderate blockages raised concerns. Author Somnath Roy stated, "Intense exercise demonstrates adverse effects on patients with moderate or higher levels of stenosis." The study discovered that intense exercise significantly amplified the shear stress at the stenosis site, which could potentially lead to the rupture of the plaque.

This ruptured plaque has the potential to travel to the brain and impede its blood supply, consequently increasing the risk of ischemic stroke. These findings underscore the importance of caution and tailored exercise regimens for individuals with moderate or severe stenosis to mitigate the potential adverse consequences associated with intense physical activity.
