Cardiovascular diseases are the diseases of Heart and blood vessels. Primarily it includes numerous problems, most of which are related to a process called atherosclerosis, a condition that develops when a substance called plaque builds up in the walls of the arteries. This buildup narrows the arteries diameter, making it harder for blood to flow through. A blood clot formed, can stop the blood flow, leading to heart attack or stroke.
Heart attack/ Myocardial infarction (MI) occurs when the flow of blood to a part of the heart is blocked by a blood clot. If this clot cuts off the blood flow completely, the part of the heart muscle supplied by that artery begins to die. Most people survive first heart attack, but it provides a warning on clogged arteries. This situation should be dealt early by involving oneself in medication techniques and have lifestyle changes according to how badly the heart was damaged and what degree of heart disease caused the heart attack
Ischemic attack (the most common type) happens when a blood vessel that feeds the brain gets blocked, usually from a blood clot. When the blood supply to a part of the brain is shut off, brain cells will die. The result will be the inability to carry out some of the previous functions as before like walking or talking. A hemorrhagic stroke occurs on bursting of blood vessel within the brain.
Other Types of Cardiovascular Disease
Heart failure: Heart failure or congestive heart failure means that the heart isn't pumping blood as well as it should. The heart keeps working, but the body's need for blood and oxygen isn't being met by that.
Arrhythmia: This is an abnormal rhythm of the heart. Arrhythmia can be of many types. Heart can beat too slow, too fast or irregularly. Bradycardia is when the heart rate is less than 60 beats per minute. Tachycardia is when the heart rate is more than 100 beats per minute. An arrhythmia can affect how well the heart works. The heart may not be able to pump enough blood to meet the body's needs.
Heart valve problems: When heart valves don't open enough to allow the blood to flow through as it should, it's called stenosis. When the heart valves don't close properly and allow blood to leak through, it's called regurgitation. When the valve leaflets bulge or prolapse back into the upper chamber, it’s a condition called mitral valve prolapse.
Angina pectoris– Literally, “pain in the chest.” It is associated with the heart and often accompanied by shortness of breath, fatigue and nausea. Angina pectoris indicates the poor condition of heart when it is protesting/ begging for more blood.
