According to The World Health Organization (WHO), cardiovascular diseases (CVD) account for 17.9 million deaths globally, making it the number 1 cause of death. A majority of deaths are due to CVDs are due to heart attack and stroke. When compared to AIDS, tuberculosis, and malaria, CVDs are responsible for 46 times the overall causes of death and 11 times the burden of disease. In this article, we discuss the different types of heart attacks and what you can do to prevent them.
Normal heart function
A healthy heart functions with a sequence of coordinated contractions that send deoxygenated blood to the lungs, which later sends oxygenated blood throughout the body. A powerful organ such as the heart, capable of sending blood to distant organs throughout the entirety of one’s lifespan, also requires a constant flow of oxygen-rich blood for it to function. This is the responsibility of the coronary arteries, which also receive their blood flow from the heart.
