What factors increase risk in everyday life?
Many factors can contribute to atherosclerosis. Smoking, hypertension, untreated high cholesterol, diabetes, obesity, and a sedentary lifestyle are all risk factors known to most people. The problem is that many of these factors can be present simultaneously and work silently for a long time.
Many people consider stress merely an unpleasant side effect, but it can severely tax the cardiovascular system over the long term. The same goes for sleep deprivation, which can easily disrupt the body's balance over time. These aren't dramatic factors, but rather factors that, in hindsight, perhaps you should have taken more seriously.
Genetics can't be ignored either. It can be relevant even if a person feels otherwise healthy, which is why it's interesting that research is also examining blood type.
What does blood type research reveal?
Based on scientific evidence, several studies have found a correlation between certain blood types and the risk of cardiovascular disease. This doesn't mean that a person with a certain blood type will inevitably have problems, but rather that the risk can vary statistically.
Some studies have found a slightly increased risk in people with blood type A. This may be because they tend to have lower levels of bad cholesterol, which can contribute to atherosclerosis. It has also been hypothesized that their blood clotting characteristics may be slightly different, which could predispose them to clot formation in certain situations.
Several studies have also highlighted an increased risk for blood type AB, although the underlying causes may be different. Some studies cite metabolic differences, such as a greater predisposition to insulin resistance, which can indirectly impact the circulatory system. It has also been found that certain inflammatory markers may be more frequently elevated, potentially causing long-term damage to blood vessel walls.
In the case of blood type AB, several studies have found the strongest association with cardiovascular problems. This blood type is rarer, but it is often highlighted because several factors can be present simultaneously, such as a worse lipid profile and a greater tendency to clot. Large follow-up studies have suggested that the risk of heart disease may be significantly higher in blood type AB than in other groups, especially when other risk factors are also present.
