Our bodies are made up of millions of cells that need oxygen and other substances to function. And the heart is responsible for pumping blood to deliver these substances through the blood vessels.
Dr. Roberto Martín Reyes , interventional cardiologist at Hospital La Luz , discusses this muscle, essential for life, and the most outstanding advances in cardiology on the program ¿Qué me pasa doctor ? on laSexta .
Cardiology studies diseases that affect the heart and blood vessels, currently the main cause of mortality worldwide.
Among the most frequent is heart failure, which occurs when there is an imbalance between the heart's ability to pump blood and the body's needs. It causes abnormal fatigue, shortness of breath when lying down, and fluid retention, among other symptoms.
On the other hand, high blood pressure occurs due to a narrowing of the small arteries responsible for regulating blood flow , forcing the heart to work harder and generating pressure in the blood vessels. This condition increases the risk of having a heart attack.
A myocardial infarction occurs when an artery becomes blocked, decreasing the amount of oxygen that reaches the heart, which causes the death of cells and the destruction of part of the heart muscle.
