Ischemic cardiomyopathy happens when your heart is unable to pump blood to the rest of your body as a result of coronary artery disease. Blood arteries leading to the heart muscle constrict and get blocked. The cardiac muscle is deprived of oxygen as a result of this. Heart failure is frequently caused by ischemic cardiomyopathy.
Hypertrophic cardiomyopathy occurs when your heart becomes thick and stiff because of excessive growth of collagen fibers in its muscle tissue. This prevents the heart from functioning properly as it fails to respond to signals from the brain that it needs more blood flow.
Dilated cardiomyopathy is also called congestive heart failure. It occurs when your heart muscles become stretched out and fail to hold enough blood within them to supply the body's other organs with vital nutrients and oxygen. The heart becomes weak and ineffective.
Alcoholism can cause cardiomyopathy through several different mechanisms. Alcohol causes inflammation of the heart tissue, which can lead to scarring and eventual replacement of normal tissue with fat or connective tissue. Heavy alcohol use can also cause hypertension (high blood pressure) and diabetes, both of which may contribute to developing cardiomyopathy.
Other factors such as viral infections, toxins, and genetics can also cause or contribute to the development of cardiomyopathy.
Heart failure, also known as congestive heart failure, happens when your heart muscle fails to pump blood as efficiently as it should. Certain disorders, such as restricted arteries in your heart (coronary artery disease) or high blood pressure, progressively weaken or stiffen your heart, making it unable to fill and pump properly. Other factors such as age, gender, and genetics may also contribute to heart failure.
Decreased cardiac function means that the heart is working too hard to pump enough blood through a weak vessel system. This can be caused by a number of different conditions. As less blood is pumped by the heart, more of it has to travel through smaller vessels. These small vessels are prone to collapse during times of stress, like when you exercise.
Without adequate blood flow, the muscles begin to waste energy trying to push blood through an area that doesn't receive enough of it. Over time, these changes lead to increased fatigue, lower levels of activity, and poorer quality of life.
There are several ways to improve cardiac function. The first step is to find the cause of the problem. This may include testing your blood for markers of heart disease or taking other tests to determine the source of your symptoms. If no serious problems are found, your doctor may suggest medications or other treatments to help prevent further damage to your heart muscle.
If you have heart failure, your goal is to give your heart time to recover.
Coronary artery disease, sometimes known as a heart attack, is the most prevalent cause. It can, however, be caused by genetic flaws. Cardiomyopathy with hypertrophy This kind involves abnormal thickening of your heart muscle, making it more difficult for the heart to function. The main cause is unknown but mutations in several genes have been linked to this condition.
Cirrhosis of the liver is another common cause of cardiomyopathy. As the liver fails, toxic substances build up in the blood and may damage the heart. Cirrhosis can also occur without any other problem being detected after careful examination; this type is called "idiopathic" or "of unknown origin".
Certain medications can also cause cardiomyopathy. These include alcohol, some drugs used to treat cancer, depression, and anxiety, and certain hormones such as estrogen and testosterone.
Finally, cardiomyopathy can be an incidental finding during surgery on the heart.
The main treatment for cardiomyopathy is still improved cardiac function. Medications are often prescribed to reduce the risk of future heart attacks and strokes. If medical management isn't effective, cardiac transplantation may be considered. In very severe cases, mechanical aids such as pacemakers and artificial hearts may be necessary.
The most common causes of cardiomegaly are congenital (patients are born with the condition due to a genetic inheritance), high blood pressure (which can enlarge the left ventricle, causing the heart muscle to weaken over time), and coronary artery disease (the latter case causes blockages in the coronary arteries). Other causes may be cancer or other diseases that cause swelling in the body.
Cardiomegaly means enlargement of the heart. The heart is a muscular pump used to circulate blood through the body. Enlarged hearts tend to be heavy and stiff, and often lack sufficient strength to supply enough blood flow to the organs. As a result, patients are at risk of developing problems with their lungs (emphysema), brain (stroke), or kidneys (renal failure). Enlarged hearts may also lead to symptoms such as shortness of breath when walking up stairs or exercising, dizziness when standing up, pain in your shoulders, neck, or back when you bend over, fatigue, and cold hands and feet.
The heart is made up of multiple chambers that work together to pump blood throughout the body. The large upper chamber is called the left ventricle, and it sends oxygen-rich blood into all parts of the body via the aorta. The small lower chamber is called the right ventricle, and it sends blood into the lungs where it gets oxygenated before releasing into the bloodstream.
When the flow of oxygen-rich blood to the heart muscle is stopped or decreased, coronary heart disease develops. This increases the pressure on the heart and can result in angina, or chest discomfort caused by limited blood supply to the heart muscle. When blood supply to the heart muscle is suddenly cut off, a heart attack occurs. As many as half of all people who have a heart attack will die as a result.
Heart disease can also lead to other problems beyond pain and fatigue. It can cause permanent damage to the heart muscle, leading to congestive heart failure. Some people who suffer heart attacks may be at risk for developing dementia as they get older. This is because areas of the brain that are not getting enough blood flow may decline in size or even disappear completely.
The most common symptom of heart disease is angina, which is pain or discomfort in the chest, arms, neck, or jaw due to lack of oxygen to the heart muscles. Other symptoms include shortness of breath, nausea, dizziness, arm pain when lifting weights, and fatigue. People with end-stage heart disease may have no symptoms at all until something triggers a heart attack. In some cases, the first sign of trouble is hearing loss or abnormal bleeding from the ears or nose. Others may experience abdominal swelling or pain, depression, anxiety, or insomnia.
