MYOCARDIAL ISCHAEMIA Meaning and
Definition
-
Myocardial ischemia is a medical term that refers to the inadequate blood flow and oxygen supply to the heart muscle, commonly caused by partial or complete blockage of the coronary arteries. The term comes from the Latin words "myocardium" meaning "heart muscle," "isch" meaning "restriction," and "haima" meaning "blood."
During myocardial ischemia, the narrowing or blockage of the coronary arteries limits the heart's ability to receive the necessary oxygen and nutrients. This condition often occurs due to the development of atherosclerosis, a process where cholesterol and other substances build up and form plaques within the arterial walls. When blood flow is severely restricted, the heart muscle becomes deprived of oxygen and nutrients, leading to tissue damage and potentially life-threatening consequences.
Common symptoms of myocardial ischemia may include chest pain or discomfort, also known as angina, which typically presents as a squeezing or pressure-like sensation in the chest. Other indications can include shortness of breath, palpitations, dizziness, and even nausea.
Prompt medical attention is essential in cases of myocardial ischemia, as prolonged deprivation of adequate oxygen supply can result in a more severe condition called myocardial infarction or heart attack. Treatment options for myocardial ischemia may include lifestyle modifications, medication, and various interventions such as angioplasty, stenting, or bypass surgery to restore blood flow in the affected coronary arteries.
Regular monitoring and management of myocardial ischemia are crucial to prevent complications and improve overall heart health.
Etymology of MYOCARDIAL ISCHAEMIA
The word "myocardial" comes from the combination of two Greek words, "myo" meaning "muscle" and "cardio" meaning "heart". The term "ischaemia" is derived from the Greek word "ischaimos", meaning "to hold back or keep back". Therefore, "myocardial ischaemia" refers to the condition where the blood flow to the heart muscle (myocardium) is inadequate or restricted, often due to a blockage in the coronary arteries.
