In atrial fibrillation, a problem with the heart's electrical system the atria to quiver, or fibrillate. The quivering upsets the normal rhythm between the atria and the lower parts (ventricles) of the heart. The lower parts may beat fast and without a regular rhythm. Atrial fibrillation is dangerous because it greatly increases the risk of stroke. If the heart doesn't beat strongly, blood can collect, or pool, in the atria.
Sweating, dizziness, nausea, fainting, or shortness of breath may also occur. The dying area may upset normal electrical activity. The heart starts a wild, twitching movement called ventricular fibrillation. Then the heart is no longer pumping blood effectively. If this happens, CPR should be administered
DEFINITION/ETIOLOGY: The most common cause of heart failure is coronary artery disease (CAD), which is a narrowing of the small blood vessels that supply blood and oxygen to the heart. Hear failure can also occur when an infection weakens the heart muscles, this disorder is called cardiomyopathy. Other heart problems that may cause heart failure include: Congenital heart disease, Heart attack, heart valve disease, and some types of abnormal heart rhythms. Diseases such as emphysema, severe anemia, hyperthyroidism, or hypothyroidism may also cause or contribute to heart failure Systolic heart failure means that your heart muscle cannot pump, or eject the blood out of the heart very well. Diastolic heart failure means that your hearts pumping chamber does not fill up with blood.
CAD is usually due to atherosclerosis, which is a formation of plaque on the artery walls, causing them to narrow. Plaque is made up of cholesterol and fatty deposits that collect over time in the wall of a coronary artery. As the plaque narrows the lumen of the coronary artery, it makes it difficult for adequate quantities of blood to flow to the heart. Initially, the reduction of blood flow may not produce any symptoms. However, a gradual reduction of blood flow can cause angina and shortness of breath.
CHF is a chronic, long-term condition although at times it can develop quite suddenly. When a heart’s muscles can no longer efficiently pump blood out of the heart wall, systolic heart failure occurs, and when blood is no longer able to fill the heart’s cavity due to stiffened heart muscles, diastolic heart failure follows. When the heart is no longer able to eject blood outside of the heart wall, blood is prevented from entering as well. This, in turn, will lead to fluid build-up in the lungs, liver, GI (gastrointestinal) tract, arms, and legs, and as a result, a lack of oxygen and nutrition to these organs and body parts ensues. Although CHF can develop on its own, other heart problems or conditions such as Congenital Heart Disease, hearts attacks, and arrhythmias (abnormal heart beats) can lead to CHF (Hunt).
By affecting the kidney, it may impair their ability to rid waste from their body. If the lungs are affected then chest pains may occur, especially while breathing. When the central nervous system is affected headaches, dizziness, memory disturbances, vision problems, seizures, strokes, and changes in behavior may appear. Depending on what part of the body is affected will determine the type of medical doctor you will need to see. Most people who have mild to moderate disease will be treated by a rheumatologist, who specializes in the diseases of joints and muscles.
a patient history of severe, prolonged chest pain, unequivocal electrocardiogram (ECG) changes that include abnormal and persistent Q waves,changes in serial cardiac biomarker levels that indicate myocardial injury and infarction. 3. What are the treatment goals for a patient with AMI? Management of acute pain includes both pain relief and interventions to reduce the thrombosis and oxygen demands. 4.
The symptoms of atherosclerosis in the coronary arteries are shortness of breath, chest pain, increased heart rate, sleep problems, fatigue or tiredness, and lack of energy. So if you are experiencing any of these symptoms you need to talk to your doctor. SLIDE
Heart Bypass Surgery If you have blockage in one or more of your coronary arteries, your doctor may want to perform a heart bypass surgery. Coronary arteries are arteries that carry oxygen and nutrients in your blood. When your arteries become blocked your heart is not getting the blood supply that it needs. This is called ischemic heart disease and can often cause chest pain also known as Angina. Sometimes, heart bypass surgery is not the first treatment for ischemic heart disease.
