Heart failure affects about 5 million people in most countries in the world. About 550,000 people with heart failure are diagnosed every year, and this is the main reason for hospitalization for older people over the age of 65.
What is heart failure?
Heart failure does not mean that the heart may stop working, but heart failure means that the force of the heart pumping is less effective than normal with a heart failure, and as a result blood moves through the heart and body at a slower rate, leading to increased pressure while the heart is pumping As a result, the heart can not pump enough blood to carry oxygen and nutrients to meet the needs of the body. Heart chambers (internal organs of the heart) may respond to heart failure, which expands to carry more blood to the body during blood pumping or May become more severe and thicker, and this helps keep the blood moving for longer than However, at times, the walls of the heart muscle may weaken and become unable to pump with the same force. As a result, the kidneys respond – kidney reaction – by causing the body to retain fluids (water) and sodium, and if accumulated Fluids in the arms, legs, ankles, feet, lungs, or other organs, the body becomes bloated, and congestive heart failure is a term used to describe such a condition.
What causes heart failure
Heart failure occurs by many conditions that pertain to myocardial infarction, including:
Coronary artery disease (CAD) is a disease of arteries that supply blood and oxygen to the heart. Causes of low blood flow to the heart muscle result from blockage of the arteries or a severe narrowing of the arteries, which causes the heart to need oxygen and nutrients.
2 – heart attack: – may occur heart attack when the coronary artery suddenly stop, stop the flow of blood to the heart muscle leads to damage, and all / or part of the heart muscle becomes cut off from the supply of oxygen, and heart attack can cause damage to Myocardial infarction, resulting in a ruptured area resulting from the operation – a blood pumping process – that occurs improperly.
3 – myocardial infarction: – Myocardial infarction and includes all of the problems of the artery or blood flow, and inflammation, and the use of alcohol and drugs.
Conditions that cause heart fatigue include several cases including: high blood pressure, heart valve diseases, thyroid disease, kidney disease, diabetes, or heart defects at birth and can cause heart failure. In addition, failure can occur Heart for many diseases or sudden circumstances.
