Why might a thrombus in a coronary artery?
Why might a thrombus in a coronary artery?
Coronary artery thrombus occurs due to rupture or erosion of preexisting coronary artery plaque, resulting in the artery’s complete occlusion. [1] It manifests clinically as an acute coronary syndrome, including ST-elevation MI, Non-ST elevation myocardial infarction, and unstable angina[2].
What are the actual pumps of the heart?
The right and left sides of the heart are further divided into two top chambers called the atria, which receive blood from the veins, and two bottom chambers called ventricles, which pump blood into the arteries.
What is the main structure of the heart?
The heart is divided into four chambers consisting of two atria and two ventricles; the atria receive blood, while the ventricles pump blood. The right atrium receives blood from the superior and inferior vena cavas and the coronary sinus; blood then moves to the right ventricle where it is pumped to the lungs.
What are the symptoms of coronary thrombosis?
A coronary thrombus is asymptomatic until it causes significant obstruction, leading to various forms of angina or eventually a myocardial infarction. Common warning symptoms are crushing chest pain, shortness of breath, and upper body discomfort.
Is coronary thrombosis fatal?
Arterial Thrombosis Acute coronary thrombosis can result in nonfatal myocardial infarction or sudden death. This process is well defined in patients with heart failure, patients with coronary artery disease, and those dying of sudden cardiac death.
What would happen if the mitral valve is unable to close?
When the mitral valve doesn’t close all the way, blood flows backward into the upper heart chamber (atrium) from the lower chamber as it contracts. This cuts down on the amount of blood that flows to the rest of the body. As a result, the heart may try to pump harder. This may lead to congestive heart failure.
What do the four chambers do?
The heart has four chambers: two atria and two ventricles. The right ventricle pumps the oxygen-poor blood to the lungs. The left atrium receives oxygen-rich blood from the lungs and pumps it to the left ventricle. The left ventricle pumps the oxygen-rich blood to the body.
What are the different structures of the heart?
The internal cavity of the heart is divided into four chambers:
- Right atrium.
- Right ventricle.
- Left atrium.
- Left ventricle.
