It occurs when the arteries that supply blood to the heart muscle harden and narrow. This is due to the accumulation of cholesterol and other materials called plaque in the inner layer of the artery walls. This accumulation is called arteriosclerosis .
As it progresses, less blood flows through the arteries . As a consequence, the heart muscle cannot receive the blood or oxygen it needs. This can lead to chest pain ( angina ) or a heart attack . Most heart attacks occur when a clot suddenly interrupts the blood supply to the heart, causing permanent heart damage.
Age and belonging to the male sex are the main factors in developing the disease. Women tend to develop heart disease after men. Female hormones are believed to help protect women from these diseases before menopause. After menopause, women have heart disease as often as men. Some of the factors that increase the chances of having heart disease are:
- High cholesterol levels.
- Blood hypertension.
- Very high saturated fat diet
- Being overweight.
- Do not exercise.
- Too much stress.
- Close inheritance with heart disease at an early age.
Over time, the disease can also weaken the heart muscle and contribute to the presence of heart failure and arrhythmias . Heart failure means that the heart cannot adequately pump blood to the rest of the body. Arrhythmias are changes in the normal rhythm of the heart .
