Disease of the Circulatory System

Hypertension

•         Blood flows through the blood vessels with a force greater than normal i.e. with a blood pressure reading of 140/90

•         When the blood pushes harder against the walls of your arteries, your blood pressure goes up

Prevention

•         Quit smoking

•         Exercise regularly

•         Reduce amount of sodium

•         Eating a healthy diet

Coronary Heart Disease/ Heart attack

•         A heart attack happens when the flow of oxygen-rich blood to a section of heart muscle suddenly becomes blocked and the heart can’t get oxygen.

•         If blood flow isn’t restored quickly, the section of heart muscle begins to die.

•         Coronary Heart disease

•         CHD is a condition in which plaque builds up inside the coronary arteries.

•         When plaque builds up in the arteries, the condition is called atherosclerosis

•         The buildup of plaque occurs over many years.

•         Coronary thrombosis-blood clot

Signs of heart attack

•         Chest pain or discomfort. Most heart attacks involve discomfort in the center or left side of the chest. 

•         Upper body discomfort: in one or both arms, the back, shoulders, neck, jaw, or upper part of the stomach

•         Shortness of breath

Causes

•         Cigarette smoking: nicotine both put a strain on the heart by making it work faster. They also increase your risk of blood clots.

•         Diet: diet high in saturated fat, will cause blood cholesterol levels will rise.

•         High blood pressure: Having poorly controlled high blood pressure  can weaken the coronary arteries

•         Being overweight or obese

•         Lack of physical activity

Cigarette smoke

•         Cause Constrict blood vessels, and increase blood pressure

•         Increase change of blood clots formation in arteries

•         About 22,700 to 69,600 premature deaths from heart and blood vessel disease are caused by other people's smoke each year.
