The most common causes of cardiomegaly are congenital (patients are born with the condition based on a genetic inheritance), high blood pressure (which can enlarge the left ventricle causing the heart muscle to weaken over time), and coronary artery disease. In the latter case, the disease creates blockages in the heart's blood supply, leading ...
Heart failure is caused by chronic oxygen deprivation due to reduced blood flow, which weakens the heart over time. Arrhythmias are caused by inadequate blood supply to the heart that interferes with the heart's electric impulse. The coronary arteries can constrict as a response to various stimuli, mostly chemical. This is known as a coronary ...
A heart attack requires immediate treatment to improve blood flow to your heart, relieve your symptoms, and prevent another heart attack. Some treatment options include: Medications such as ...
Coronary artery disease (CAD), also called coronary heart disease (CHD), or ischemic heart disease (IHD), [13] is a type of heart disease involving the reduction of blood flow to the cardiac muscle due to a build-up of atheromatous plaque in the arteries of the heart. [5] [6] [14] It is the most common of the cardiovascular diseases. [15]
Reduced blood flow to the heart associated with coronary ischemia can result in inadequate oxygen supply to the heart muscle. [6] When oxygen supply to the heart is unable to keep up with oxygen demand from the muscle, the result is the characteristic symptoms of coronary ischemia, the most common of which is chest pain. [6]
The treatment consists of drugs, mainly to relieve chest pain, but a very important part of the treatment is regularly visiting the doctor and repeating the tests to make sure the condition was taken care of in full. The first step in managing Microvascular angina is the administration of nitrates which may relieve the chest pain. They are used ...
Arterial grafts originate from the part of the internal thoracic artery (ITA) that runs near the edge of sternum, and can easily be mobilized and anastomosed to the native target vessel of the heart. The left artery is most often used because it is closer to the heart, but the right artery is sometimes used, depending on patient and surgeon ...
A coronary occlusion, or coronary artery disease, is the partial or complete obstruction of blood flow in a coronary artery. This condition may cause a heart attack . [ 1 ] It is the most common form of cardiovascular disease , and is the leading cause of death in the United States, affecting 18 million adults.
