Document Summary
"atheroma"); also known as a "fibrofatty plaque" or just plain "plaque": atherosclerosis - a disease of large and medium-sized arteries. 140 mmhg and/or a diastolic pressure consistently greater than 90 mmhg. Infarction - a localized area of ischemic necrosis produced by blockage of the arterial supply or its venous drainage. Atherosclerosis: atherosclerosis is a systemic disease affecting large and medium-sized arteries. 5: angina is chest pain, which is the result of myocardial ischemia, and this blood. If myocardium is ischemic for about 30 - 40 minutes, it begins to die, and the result is a myocardial infarct (mi). It is therefore important to seek prompt medical attention when an anginal episode does not resolve within this time period. Note the area of necrotic infarct in the wall of the left ventricle and septal region (at tip of arrows - see areas of soft, yellowish tissue). Infarct size is variable; prognosis is worse for larger lesions.
