Pulmonary artery stenosis, or PCAS, is a common heart disease that develops a narrowing of a narrow blood artery in the lung, the large, main artery that carries blood from the upper heart through the body and to the lungs. This narrowing can force the lungs to take in less oxygen than they need, causing high blood pressure and an enlarged heart in the side of the chest.
The arteries in the lungs are lined by smooth muscle and provide for an airtight seal against the walls of the chest cavity
As long as the blood is flowing, there should be no problem. However, if the flow of blood is not steady and regular, there may be a buildup of build up of fluid and fatty deposits in the walls of the lungs, making it difficult for the walls of the lungs properly function. When this happens, the flow of blood through the body and the breathing of those who have this condition becomes much more difficult.
One of the main problems is that arteries do not have blood vessels at the ends of their body. This allows you to create more pressure in the arteries, as well as the accumulation of fluid and fatty deposits in the walls of the arteries. There are several factors that contribute to this problem. Some of these factors include high blood cholesterol, obesity, and a sedentary lifestyle. The more in your body, the more difficult it is to keep it moving and healthy.
For example, high cholesterol, high blood cholesterol, obesity and sedentary lifestyle are the number one risk factors for developing this condition. If you already have high cholesterol levels, you are more likely to develop this condition. These factors also increase your chances of developing other complications such as heart disease, stroke, and even aneurysm.
The arteries of the chest wall, along with the lungs, are surrounded by soft tissues called the pleura. As long as the walls of these walls and the lungs are healthy, there is no real danger of developing this condition. Over time, however, this can lead to a buildup of fluid and fatty deposits on the walls of the arteries, making them less flexible, allowing less blood to pass through them, putting more pressure on the walls and causing them to enlarge.
When this happens, blood flow is not enough to keep the arteries moving properly, causing the walls to relax. This causes the flow of blood to stop and the breathing to slow. When this condition gets worse, the lungs can get the pressure it as well, causing a feeling of shortness of breath and chest pain. Eventually, the person may lose consciousness.
A third major risk factor for this type of heart condition is smoking. Smokers often have a greater chance of developing this than non-smokers, because smoking relaxes the walls of arteries that may have a tendency to become narrowed, especially those in the chest. Those who smoke are at a greater risk because of their increased chances of developing more serious heart problems, including a buildup of fat in these arteries.
Even though you might think you do not have a good chance of having this condition, it is wise to quit smoking and try to reduce your overall weight as much as possible. Smokers who want to lower their chances of developing this heart condition should be aware that they should also stay away from foods high in saturated fats, and cholesterol, especially if they are trying to lower their cholesterol levels.
