Blocking Effects Due to High Blood Pressure

When a person has high blood pressure and blood cholesterol levels, it leads to formation of plaque on the artery walls. This gradually leads to formation of large clots that completely block the artery pathways.Therefore, blocking effects include the eventual complete blockage or gradual narrowing of arteries by clots. Both of which stop or reduce the blood flow to all parts of the body.

Where do blocking effects happen?

Here are a list of the parts of the body where blocking effects usually happen.

Heart:

Complete blockage of a coronary artery damages part of the heart muscle (myocardial infarction or coronary thrombosis, a heart attack). Whereas, partial blockage of coronary arteries causes pain in the chest when you walk up stairs and hills.

Aorta:

The largest artery in the body is called the aorta, which is the most elastic normally. After many days of high blood cholesterol and high blood pressure, it becomes less elastic because of the formation of plaque. Then, it stretches to develop a swelling like a sausage-shaped balloon in the upper abdomen. Blood clots form on this aortic lining roughened by plaque which gradually develop more in depth or to an inch. Such clots may break loose and spread to an artery supplying in a thigh artery or supplying a kidney, thus interrupting the supply of blood to legs or kidneys.

Legs and feet:

The complete leg arteries may be blocked either by plaque forming in the thigh arteries or originating in the aorta. This causes gangrene in the foot or toes. Partial blockage of arteries of thigh or the lower trunk causes calf pain when walking uphill.

Brain:

Plaque roughens the carotid arteries which may cause formation of blood clots that can break up into tiny fragments called micro-emboli. These small fragments travel to the brain and cause giddiness, confusion or faintness that last for a few seconds and temporary loss of vision. Then, they break down into tiny particles and cause no further effects.

If it does not break up into tiny fragments, and instead travels to the brain as a large embolus, it can cause complete blockage to the brain arteries causing an embolic stroke.
