silent myocardial ischemia

Silent ischemia Cardiology Objective–eg, EKG–ST-segment depression, perfusion defects, radionuclide angiography or echocardiography of myocardial ischemia without associated Sx–ie, crushing precordial anginal pain Prognosis SMI is an independent predictor of poor clinical outcome in Pts with CADSee Angina, Myocardial infarction, Total ischemic burden.
Silent myocardial ischemia
True silent ischemia The nociceptive pathways have a marked ↓ in sensitivity to pain, as occurs in DM, present in 10-20% of Pts with both CAD and DM resulting in significant coronary artery spasms
Pseudosilent ischemia The Pt either
• Denies pain, recognizing both its import, and that myocardial ischemia would have an immediate impact on lifestyle or
• Recognizes the pain but attributes it to something else, ie heartburn

However, it is important to note that the incidence of silent myocardial ischemia secondary to coronary vasospasm is more than twice than that of symptomatic ischemia [7] as in this case where the phenomenon was detected incidentally from ECG or cardiac monitoring.
Recently, the cross-sectional study screened the performance of ABI, microalbuminuria, and harmonics of the radial pulse to stratify the risk of SCAD and severe silent myocardial ischemia in patients with T2DM and had at least one traditional risk factor.

This is known as the coronary steal phenomenon.3 Circulatory insufficiency, myocardial infarction, and life-threatening cardiac dysrhythmias are the most common clinical presentations during infancy.2,3 Older patients carry the risk of sudden death due to myocardial infarction, left ventricular dysfunction and mitral regurgitation, or silent myocardial ischemia.

Objective: To determine the frequency of positive exercise tolerance test (ETT) for silent myocardial ischemia in asymptomatic uncomplicated type 2 diabetic patients.
AMSTERDAM -- Sixty percent of all myocardial infarctions and cardiovascular deaths in a large population of stable outpatients with coronary artery disease occurred in patients with neither anginal symptoms in daily life nor evidence of silent myocardial ischemia.
Atypical chest pain symptoms commonly seen in women, the elderly and silent myocardial ischemia patients are also reviewed.
SAN DIEGO -- Nearly 80% of patients with type 2 diabetes who had silent myocardial ischemia revealed by stress myocardial perfusion imaging had a reversal of exercise-induced myocardial perfusion abnormalities when they were retested 3 years later.
(13) Silent myocardial ischemia occurs in more than 20% of asymptomatic diabetic patients.

New research shows that people with coronary artery disease who awaken at night -- particularly those who get out of bed -- risk suffering an episode of silent myocardial ischemia, a temporary and often painless reduction in blood flow to the heart muscle.
