Cardiovascular Heart Disease
Cardiovascular heart disease (CVD) refers to the disease of the human heart or blood vessels. The heart is the strongest muscle in the human body. It works persistently throughout our life, from 21 to 28 days after conception (that is before we are born) and up till the day we die. On average the average heart beats about 100,000 times a day at approximately 70 to 80 times a minute. However, the heart beat rate can double during physical exercise or at times of emotion. When it beats blood is pumped through the blood vessels or arteries to other parts of the body.
Cardiovascular system is two words taken together as one. The first part is “cardio” meaning the heart and the second part is “vascular” meaning a system or network of blood vessels. The system is essential for life. The cardiovascular system is often referred to as the circulatory system. The blood travels from the left side of the heart, rich in oxygen through the arteries that are of decreasing sizes till it reaches the capillaries in all the organs and parts of the body. These capillaries are the narrowest of arteries. The blood then travels delivering oxygen and nutrients and collecting waste products on its way back to the right side of the heart through a system of increasingly enlarging veins. This is process is referred to as the circulatory system or cardiovascular system. However the flow of blood to the heart or other parts of the body and brain may not always be smooth or regular. It can be reduced as a result of a blood clot (thrombosis) and build-up of fatty deposits in the artery, causing the artery to harden and narrow (atherosclerosis).
Cardiovascular heart disease (CVD)
CVD can be classified into four main types. These are:
- coronary heart disease (CHD)
- aortic disease
- peripheral arterial disease
A stroke occurs when the blood supply to the brain is disturbed. As with other human organs, the brain requires a regular supply of oxygen and nutrients to effectively carry out its role. The blood provides these oxygen and nutrients. Therefore, if the blood supply is constrained or stopped then the brain cells begin to die, which may result in brain damage and may result in death. Stroke is considered a medical emergency, requiring prompt treatment in order to reduce possible damage or the level of damage. So the sooner a stroke victim receives treatment, the less damage they are likely to suffer. (See Stroke And The After Effect) Stroke symptoms vary. However, the four main symptoms have the acronyms “FAST”, which stands for:
- Face– one side of the face of a stroke patient may have drooped, such that the person may not be able to smile.
- Arms– the patient with suspected stroke may suffer weakness or numbness in their arm. So they may not be able to lift their arm and keep it raised.
- Speech– the stroke patient may not be able to speak even when they appear to be awake or their speech may be slurred or garbled.
- Time– time is of the essence for a stroke victim, because the sooner you get medical help the better the level the damage. So if you notice any of the above stroke signs or symptoms get medical help immediately.
Coronary heart disease
The causes of coronary heart disease (CHD) are anything that can block or interrupt the heart’s blood supply. The blockage or interruption is mainly caused by a build-up of fatty substances (atheroma) in the two major blood vessels that supply the heart with blood. These blood vessels are the coronary arteries. If a build-up of atheroma caused the coronary arteries to become narrow then it will restrict the blood supply to the heart. This may cause the person to suffer chest pains (angina). When the coronary artery is completely blocked, it can cause person to suffer heart attack.
The aorta carries blood from the heart to the rest of the body. It is the largest blood vessel in the body. The aortic aneurysm is the most common type. Aorta aneurysm is where the wall of the aorta becomes weakened and bulges outwards. The symptoms the patient will suffer include pain in the chest, back or abdomen. For more information about aorta aneurysm, please see Aneurysm: Blood Vessel Disorder
Peripheral arterial disease
Peripheral arterial disease may also be referred to as peripheral vascular disease. The disease occurs when there is a blockage in the arteries to the limbs (mainly the legs). The usual peripheral arterial disease symptom is pain in one or both of the thighs, hips or calves (in the legs) while walking. The patient may experience a pain in the leg muscles that may be in the form of a sensation of heaviness, a cramp, or a dull pain. Normally, the pain will come and go but will get worse when doing physical exercise that requires the use of the legs. These include normal walking or climbing up the stairs.
Cardiovascular Disease Causes
Cardiovascular disease causes may be due to a number of risk factors. Some of these risk factors may be linked, meaning that if the patient has one they may also have some of the others. However, the main causes are:
- high blood pressure or hypertension, which may result in damage artery walls and blood clot. See High blood pressure (hypertension)
- High blood cholesterol- may cause the arteries to narrow and increase the risk of developing a blood clot.
- smoking – tobacco toxins can also cause damage and narrow the coronary arteries. See Stop smoking to boost your good cholesterol
- poor diet – diets high in fats can increase the rate of formation of fatty deposits in the arteries, which causes high blood cholesterol levels as well as high blood pressure. See A diet that prevents heart attack
- diabetes – type 1 and type 2 diabetes can damage the arteries. See Reduce Your Diabetes Risk
- lack of exercise – normally causes higher cholesterol levels, high blood pressure and high stress levels.
- overweight or obese – causes diabetes and high blood pressure.
- excessive alcohol consumption, increases cholesterol levels and blood pressure.
- stress – increases blood pressure and may also the blood glucose levels.
