So I began to think. It links together the sympathetic and parasympathetic nervous system, with the actions of the stress hormones, the adrenal glands, thyroxine, glucagon, insulin etc. A complex beast of a thing. Bjorntorp established that chronic psychological stress chronic strain creates a dysfunction of the HPA-axis that can be monitored, most easily, by looking at twenty-four-hour cortisol secretion.
What is Heart Disease? Kristy Haugen The term heart disease is a very broad term. Problems can arise within the heart muscle, arteries supplying blood to the heart muscle, or the valves within the heart that pump blood in the correct direction.
Understanding the differences between each disease of the heart can help with the confusing applications of the term heart disease. Coronary artery disease affects the arteries supplying blood to the heart muscle.
These coronary arteries harden and narrow due to the buildup of a waxy cholesterol, fatty substance referred to as plaque. This plaque buildup is known as atherosclerosis. The increase in plaque buildup causes the coronary arteries to become narrower.
This will cause blood flow to become restricted, decreasing the amount of oxygen delivered to the heart muscle. Decreasing the amount of oxygen supplied to the heart muscle can cause angina chest pain and lead to a heart attack. Coronary artery disease over time can weaken the heart muscle contributing to heart failure and arrhythmias abnormal heart rhythms.
Coronary heart disease is another confusing type of heart disease. Coronary heart disease is not the same thing as coronary artery disease. While coronary artery disease refers to the coronary arteries, coronary heart disease refers to the diseases of the coronary arteries and resulting complications.
This includes such complications such as chest pain, a heart attack, and the scar tissue caused by the heart attack. Understanding this subtle difference between the two may impress your cardiologist. Cardiomyopathy is a disease affecting the muscle of the heart.
Cardiomyopathy can be genetic or caused by a viral infection. Cardiomyopathy can be classified as primary or secondary. Primary cardiomyopathy is attributed to a specific cause hypertension, congenital heart defects, heart valve disease. Secondary cardiomyopathy is attributed to specific causes diseases affecting other organs.
There are three main types of cardiomyopathy. Dilated cardiomyopathy is enlargement and stretching of the cardiac muscle. Hypertrophic cardiomyopathy causes thickening of the heart muscle. Restrictive cardiomyopathy causes the ventricles of the heart to become excessively rigid causing blood flow to the ventricles to be difficult between heartbeats.
Valvular heart disease is a disease that affects the valves of the heart. Valves within the heart keep the blood flowing in the correct direction. Damage to valves can be caused by a variety of conditions leading to regurgitation or insufficiency leaking valveprolapse improper closing of the valveor stenosis narrowing of the valve.
Valvular heart disease can be genetic.
Valvular heart disease can also be caused by certain infections such as rheumatic fever, and certain medications or radiation treatments for cancer.Coronary heart disease is the major cause of death in Western societies but to a large extent is preventable.
Recognising the key risk factors which contribute to the development of atherosclerosis is an important step towards reducing the overall incidence of coronary heart disease. By , it is predicted that million people will die from cardiovascular diseases annually, mostly due to stroke and heart disease.
For women in the United States, heart disease is the. Causes. A hiatal hernia occurs when weakened muscle tissue allows your stomach to bulge up through your diaphragm. It's not always clear why this happens. The Causes Of Coronary Heart Disease Biology Essay Introduction.
