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.
When plaque builds up in the arteries, it reduces, or eventually blocks where blood can flow. CAD over time can weaken the heart muscle, cause an irregular heartbeat, cause heart failure, or lead to death. Treatment and prevention are vital to caring for a patient with CAD. Treatment occurs after a patient has been diagnosis with CAD. They have either suffered a myocardial infarction or simply had angina (chest pain) that was evaluated with coronary angiography.
Coronary Artery Disease Coronary Artery Disease is also known by other names such as, Atherosclerosis, hardening of the ateries, heart disease, Ischemic heart disease and narrowing of the arteries. Coronary Artery Disease is where one or more of the arteries supplying blood to the heart muscle become blocked. It is a disease in which a waxy substance called plaque builds up inside the coronary arteries. These arteries supply oxygen rich blood to the heart muscle. Atherosclerosis is a multi focal, smoldering immunoinflammatory disease of medium sized and large arteries filled by lipids.
HEART FAILURE This is also referred to as Congestive heart failure. it is a clinical syndrome which occurs when the heart is unable to pump sufficient amount of blood to meet the metabolic requirement of the tissue for oxygen. It can also result from structural cardiac abnormalities which impair the ability of the ventricle to fill or eject blood. The heart is weakened and cannot pump enough blood as strongly as before this implies that less oxygen is reaching the organs and muscles which can cause tiredness or shortness of breath. Etiology of cardiac failure: • Systemic hypertension-The most common cause in 75% of cases • Changes in the structure of the heart -changes in the valves causes volume and pressure overload • Disease conditions-valvular
Coronary Artery Disease (CAD) or also referred to as Coronary Heart Disease (CHD), a heart disease that develops when your coronary arteries, the major blood vessels that supply your heart with blood, oxygen and nutrients become damaged. CHD is a term used commonly for buildup of plaque in the hearts arteries that could lead to heart attack. Cholesterol containing deposits, also known as plaque on your arteries is to blame for CAD. With CAD, the plaque starts to first grow in the coronary arteries until blood flow to the heart’s muscle becomes limited, in other words, ischemia. It could be chronic and is caused by the narrowing of the coronary artery and limitation of blood supply to part of the muscle.
The resulting ischemia (restriction in blood supply) and ensuing oxygen shortage if left untreated for a sufficient period of time, can cause damage or death (infarction) of heart muscle tissue (myocardium). Cardiac Arrest is an “electrical“ problem while Heart Attack is a “circulation“ problem. Sudden cardiac arrest is not a (myocardial infarction) heart attack, but can occur during a heart attack. Heart attacks occur when there is a blockage in one or more of the arteries to the heart, preventing the heart from receiving enough oxygen-rich blood. If the oxygen in the blood cannot reach the heart muscle, the heart becomes damaged, or the part of the heart that does not receive oxygen and nutrients becomes
Abstract The impact of stress on a person’s life is well documented. The effect of stress on cortisol and catecholamine levels leading to atherosclerosis and resulting in coronary artery disease may leave the person with a poorer quality of life. Medical interventions for heart disease include medication to lower cholesterol and vasodilator to assist blood flow to the heart. Treatments for stress are antidepressants and therapeutic techniques. In this case study, the personality of a heart disease candidate is discussed and the nature of the illness and its effects on the person.
ECG shows how fast the heart is beating, whether the rhythm of the heartbeat is steady or irregular and also the strength and timing of electrical signals as they pass through each part of the heart. Medical professionals use ECG to detect and study many heart problems, such as heart attacks, arrhythmias and heart failure. The test’s results also can suggest other disorders that affect heart failure. Health history is a collection of information obtained from the patients and from other sources concerning the patient’s physical status as well as his or her psychological, social and sexual function (Mcfrerran, 2008). Health history will be based on a 45 year old iTaukei lady living in Cunningham Stage 1 with her husband and three sons.
Increased blood pressure can cause your blood vessels to weaken and bulge, forming an aneurysm. If an aneurysm ruptures, it can be life-threatening. Heart failure. To pump blood against the high pressure in your vessels, your heart muscle thickens. The thickened muscle may have a hard time pumping enough blood to meet your body’s needs, which can lead to heart failure.
