Unstable angina is a type of angina pectoris [1] that is irregular or more easily provoked. [2] It is classified as a type of acute coronary syndrome. [3]It can be difficult to distinguish unstable angina from non-ST elevation (non-Q wave) myocardial infarction.
If the ECG does not show typical changes consistent with STEMI, the term "non-ST segment elevation ACS" (NSTE-ACS) may be used and encompasses "non-ST elevation MI" (NSTEMI) and unstable angina. The accepted management of unstable angina and acute coronary syndrome is therefore empirical treatment with aspirin, a second platelet inhibitor such ...
For example, TIMI scores are frequently used to take advantage of EKG findings to prognose patients with MI symptoms. [10] Based on symptoms and electrocardiographic findings, practitioners can differentiate between unstable angina, NSTEMI and STEMI, normally in the emergency room setting. [11]
A resting electrocardiogram (EKG) is an early step in the diagnostic process. [11] An electrocardiogram (EKG) involves the use of electrodes that are placed on the arms, chest, and legs. [29] These sensors detect any abnormal rhythms that the heart may be producing. This test is painless and it helps detect insufficient blood flow to the heart ...
ST segment depression and T-wave changes may be seen in patients with unstable angina; Depressed but upsloping ST segment generally rules out ischemia as a cause. Also, it can be a normal variant or artifacts, such as: Pseudo-ST-depression, which is a wandering baseline due to poor skin contact of the electrode [3]
Wellens' syndrome is an electrocardiographic manifestation of critical proximal left anterior descending (LAD) coronary artery stenosis in people with unstable angina. Originally thought of as two separate types, A and B, it is now considered an evolving wave form, initially of biphasic T wave inversions and later becoming symmetrical, often ...
A subsequent study distinguished this type of angina from classical angina pectoris further by showing normal coronary arteries on cardiac catheterization. This finding is unlike the typical findings in classical angina pectoris, which usually shows atherosclerotic plaques on cardiac catheterization. [3]
EKG, chest x-ray, echocardiography, and angiography are needed if suspicion for myocardial ischemia or infarction is present. [7] Patients with systemic allergic reactions associated with clinical, electrocardiographic, angiographic, echocardiographic and laboratory findings of acute myocardial ischemia should be diagnosed as having Kounis ...
