It could be chronic and is caused by the narrowing of the coronary artery and limitation of blood supply to part of the muscle. It also could be acute, which is the result from plaque suddenly rupturing. The inner wall of an artery is damaged. Some fatty deposits or plaques made up of cholesterol and other cellular waste products will accumulate at a site of injury in a process called atherosclerosis, the hardening of arteries. If the surface of the plaques break or rupture, blood cells, called platelets will clump or clot at that site to try and repair the artery.
It can lead to complications. Atrial fibrillation may lead to blood clots forming in the heart that may circulate to other organs and lead to blocked blood flow (ischemia)” The danger of this disorder is that the heart may not be able to pump enough blood to support the functioning of the body. There are some patients who will have some, all, or no symptoms at all. Some symptoms include: • “Palpitations, which are sensations of a racing, uncomfortable, irregular heartbeat or a flip-flopping in your chest • Weakness • Reduced ability to exercise • Fatigue • Lightheadedness • Dizziness • Confusion • Shortness of breath • Chest pain Atrial fibrillation may be: • Occasional. In this case it's called paroxysmal (par-ok-SIZ-mul) atrial fibrillation.
Sudden cardiac arrest is different from a heart attack, which occurs when blood flow to a portion of the heart is blocked. However, a heart attack can sometimes trigger an electrical disturbance that leads to sudden cardiac arrest. Sudden cardiac arrest is a medical emergency. If not treated immediately, it causes sudden cardiac death. With fast, appropriate medical care, survival is possible.
A rise in systolic blood pressure will also increase the chance for heart attacks, strokes, and kidney failure. Your physician will use both the systolic and the diastolic blood pressure to determine your blood pressure category and appropriate prevention and treatment activities. If your Systolic blood pressure reading is
Stroke Awareness Health Assessment The self-risk assessment I chose to complete was about strokes. A stroke occurs when blood supply to the brain is temporarily interrupted or disturbed. Being that the brain requires a constant flow of oxygen any interruptions could prove to be fatal. The two types of strokes are Ischemic or hemorrhagic. An ischemic stroke is typically caused by excess buildup of plague on the blood vessel walls that narrows blood flow dramatically.
Atherosclerosis is a multi focal, smoldering immunoinflammatory disease of medium sized and large arteries filled by lipids. (Curtis M. Rimmerman, 2008) When plaque builds up the condition is called Atherosclerosis, the build up of plaque over many years.If the flow of oxygen rich blood to your heart muscle is reduced or blocked, Angina or a heart attack can occur. Angina is chest pain or discomfort. It may feel like pressure or squeezing in your chest. Pain can also occur in the shoulders, arms, neck, jaw or back.
When blood pressure is high, it starts to damage the blood vessels, heart, and kidneys. This can lead to heart attack, stroke, and other problems. High blood pressure is called a “silent killer,” because it doesn’t usually cause symptoms while it is causing this damage. Your blood pressure consists of two numbers: systolic and diastolic. Someone with a systolic pressure of 120 and a diastolic pressure of 80 has a blood pressure of 120/80, or “120 over 80.” * The systolic number shows how hard the blood pressure pushes when the heart is pumping.
It also may due to a hemorrhage. - When the clot is block or impaired of the blood flow, it will depriving the brain from essential oxygen and nutrient. B. Hemorrhagic Stroke - Occured when blood vessel ruptured and causing leakage of blood in or around the brain. Basically, the term cerebrovascular accident (CVA) is used interchangeably with stroke to refer to the vascular conditions of brain. Clinically, a variety of facal deficits are possible including changes in the level of consciousness and impairments of sensory, motor, cognitive, perceptual and language functions.
Smoking: * Causes the platelets in your blood to clump together easily by making your blood cells more "sticky" and more likely to form clots. Clumping platelets can then block your coronary arteries and cause a heart attack. * Can cause spasms in your coronary arteries, which can reduce the blood flow to your heart in a way similar to that of atherosclerosis. * Can trigger irregular heartbeats (arrhythmias). * Lowers "good" cholesterol (high-density lipoprotein, or HDL).
Coronary artery disease is the leading cause of death for both men and women in the U.S. When the coronary arteries become partially blocked or clogged the result becomes coronary artery disease. Therefore this blockage limits the flow of blood from the coronary arteries, which are the major arteries supplying oxygen-rich blood to the heart. When the heart is working harder and needs more oxygen the coronary arteries expand. Here are a few examples of when the arteries expand, when a person is climbing stairs, exercising, or having sex.
