[vc_row][vc_column][vc_column_text]In general terms, ischemia is the reduction or interruption of blood flow to a part of the body. This results in a decreased supply of both oxygen and essential nutrients to the affected tissues.<\/p>\n
When oxygen and nutrients are lacking, cellular damage can occur, and if left untreated, it can lead to tissue death, known as necrosis.<\/p>\n
The causes of ischemia can be diverse, including atherosclerosis <\/a>(narrowing of blood vessels), the presence of blood clots, or compression of the vessels due to swelling or tumors.<\/p>\n The severity of the situation depends on the duration of the blood flow interruption and the type of organ or tissue affected.<\/p>\n Some forms of ischemia may be temporary and reversible, while others can cause permanent damage.<\/p>\n When explaining what ischemia is and the types that exist, they are generally classified based on the duration or the area affected by the blood flow interruption:<\/p>\n Among the various types of ischemia\u2014such as subepicardial ischemia, intestinal ischemia, lower limb ischemia, ischemic heart disease, and cerebral ischemia \u2014 are ischemic heart disease and cerebral ischemia are among the most common.<\/p>\n Ischemic heart disease<\/a>, also known as coronary artery disease, is a condition in which blood flow to the myocardium (the heart muscle) is reduced or blocked, typically due to the buildup of fatty plaques in the coronary arteries. These arteries are responsible for supplying both nutrients and oxygen to the heart.<\/p>\n In cardiac ischemia, blood flow is reduced, and the heart cannot receive enough oxygen. This may cause angina <\/a>(chest pain) or, in more severe cases, myocardial infarction (heart attack). Ischemic heart disease is one of the leading causes of death worldwide.<\/p>\n Cerebral ischemia is a condition in which blood flow to the brain is interrupted or reduced. This limits the supply of oxygen and essential nutrients needed for proper brain function.<\/p>\n Cerebral ischemia can lead to an ischemic stroke, one of the main causes of disability and mortality. Depending on the affected area, it can be focal cerebral ischemia, affecting a specific region of the brain, or global cerebral ischemia, which impacts the entire brain.<\/p>\n Regardless of the affected area, reduced blood flow can cause severe damage to the tissue, organ, and, of course, the overall health of the person.<\/p>\n At the ABC Medical Center\u2019s Vascular, Arterial, and Venous Disease<\/a> Department, we can provide you with specialized care.
