A bad habit causes even more damage to the heart than previously thought. This conclusion was reached by scientists from the University of Copenhagen.
For decades, researchers have known that smoking provokes blockage of the arteries, and this is a direct path to heart attacks and strokes. A study involving almost 4,000 people showed that cigarettes make hearts denser and weaker, which is why they have great difficulty pumping blood through the body. And the more a person smokes, the weaker his heart works.
However, observations have also shown that after quitting smoking, the heart can, as they say, recover. Therefore, it is never too late to quit smoking, as cardiologists from Denmark emphasize. They proved that smoking threatens not only the blood vessels, but also the whole heart.
Dozens of studies have shown that smoking is associated with heart failure. Nicotine dangerously increases the heart rate and increases blood pressure. When burning a cigarette, various toxic substances are released, including carbon monoxide, which replaces oxygen in the blood, thereby reducing its availability to the heart.
