How does diabetes affect the presentation of myocardial infarction?
Factors unique to diabetes increase atherosclerotic plaque formation and thrombosis, thereby contributing to myocardial infarction. Autonomic neuropathy may predispose to infarction and result in atypical presenting symptoms in the diabetic patient, making diagnosis difficult and delaying treatment.
What are the five types of myocardial infarction?
Five Types of MI Will Make Up New Definition
- A primary coronary event, such as plaque rupture or dissection.
- A problem of oxygen supply and demand, such as coronary spasm, coronary embolism, arrhythmia, anemia, or hypotension.
What are the biochemical events that lead to MI?
Myocardial infarction (MI) usually results from an imbalance in oxygen supply and demand, which is most often caused by plaque rupture with thrombus formation in an epicardial coronary artery, resulting in an acute reduction of blood supply to a portion of the myocardium.
Why does diabetes cause myocardial infarction?
Why there is silent MI in diabetes?
When it comes to silent heart attacks, diabetics are particularly susceptible for a couple of reasons: Higher Risk of Heart Disease – Diabetic patients are at an increased risk of silent heart attack in large part because the condition has already put their heart in a more precarious position overall.
What does inferior infarct on ECG mean?
An inferior myocardial infarction (MI) is a heart attack or cessation of blood flow to the heart muscle that involves the inferior side of the heart. Inferior MI results from the total occlusion of either the right coronary artery in 85% of the cases or the left circumflex in 15% of the cases.
What is inferior MI?
An inferior wall MI — also known as IWMI, or inferior MI, or inferior ST segment elevation MI, or inferior STEMI — occurs when inferior myocardial tissue supplied by the right coronary artery, or RCA, is injured due to thrombosis of that vessel.
What is the best cardiac marker?
Troponin I is highly specific to the heart and stays higher longer than creatinine kinase-MB. Current guidelines from the American Heart Association (AHA) say this is the best biomarker for finding a heart attack. The AHA says to limit use of the other biomarkers. These include CK, CK-MB, and myoglobin.
What does inferior myocardial infarction mean?
Which complication is most likely to occur after a myocardial infarction MI )?
Ventricular free wall rupture. VFWR is the most serious complication of AMI. VFWR is usually associated with large transmural infarctions and antecedent infarct expansion. It is the most common cause of death, second only to LV failure, and it accounts for 15-30% of the deaths associated with AMI.
