The cardiovascular system is made up of the blood vessels and the heart. The cardiovascular system is responsible for delivering oxygen and nutrients to the relevant tissues and also facilitating waste products to the relevant organs for elimination. The blood vessels are made up of arteries and veins. Blood is carried to the rest of the body from the heart by the arteries while the veins help in carrying blood to the heart from the body. Due to one reason or the other, cardiovascular system may be affected by diseases or conditions that impair their proper functioning.
Symptoms of cardiovascular problems
Symptoms vary from one disease to the other. However, the following symptoms cut across all the cardiovascular diseases:
- Having shortness of breath – This condition is called dyspnea.
- Feeling fatigue and nausea
- Pressure or pains in the chest region – This may be indicator of angina
- Discomfort or pain in the arms, back, jaw, elbow
- Fainting and at times having a cold sweat.
As mentioned above, these symptoms are the most common and may vary from one person to another. Cardiovascular diseases The following are some of the diseases that are related to the heart (cardiac):
- Heart failure – this is a condition that is chronic and normally progressive where the muscles of the heart are unable to pump blood in sufficient quantity needed to meet the requirements of the body. The result is fatigue and having shortness of breath. Walking and doing simple chores become difficult.
- Heart attack – caused by a blood clot which has blocked the artery. This blockage starves the heart muscles of oxygen resulting in permanent damage to the muscle cells.
- Arrhythmia – This refers to the change in electrical impulses resulting in the heart beats being too slow, too fast or erratic. The pumping of blood is not effective in the process starving the brain, lungs and other vital organs. This will, in the long run, lead to damage or complete shutdown of these organs.
- Angina: This is the discomfort or pain caused when blood rich in oxygen does not reach the heart muscles. This discomfort may spread to areas like the back, jaw, arms, neck, etc. There is a feeling of pressure in the chest or indigestion.
- Pulmonary artery disease – this is the enlargement of the right ventricle of the heart. The effect is that there is a failure to respond to the high blood pressure or vascular resistance in the lungs. The lungs and the heart are intricately related. A negative effect on one of them will affect the other.
Cardiovascular diseases are largely caused by the lifestyles we lead. The choices that we make in this regard can greatly reduce our chances of having these diseases.Common cardiovascular problems in people…
