Revascularization for Silent Ischemia?

Silent Ischemia

Myocardial ischemia can occur without overt symptoms. In fact, asymptomatic (or silent) ST-segment depression during ambulatory electrocardiogram monitoring occurs more often than symptomatic ST-segment depression in patients with coronary artery disease. Initial studies documented that silent ischemia provided independent prediction of adverse outcomes in patients with known and unknown corona...

Coronary revascularization for myocardial ischemia.

Do transmyocardial and percutaneous laser revascularization induce silent ischemia? An assessment by exercise testing.

BACKGROUND Transmyocardial and percutaneous laser revascularization (TMR, PTMR) may reduce angina and increase exercise tolerance in otherwise untreatable angina patients, although the mechanism is unknown and the placebo effect may be significant. One other proposed mechanism is cardiac denervation leading to silent ischemia. METHODS Electrocardiograms obtained during symptom-limited exercis...

Silent myocardial ischemia.

Silent myocardial ischemia is increasingly recognized as a common phenomenon in a variety of people with coronary artery disease. The natural history is poorly understood, but available data suggest that silent ischemia adversely affects prognosis in all groups studied. Based on this information, we believe that efforts should be directed at detecting and aggressively treating silent ischemic e...

Ischemia-Guided Percutaneous Revascularization

Submit Manuscript | http://medcraveonline.com The study of Hachamovitch et al. [3] emphasized the relationship between inducible ischemia on SPECT and the presence of shortterm survival benefits with early revascularization vs. medical therapy.Revascularization was associated with a reduction in mortality for patients having moderate to severe ischemia. The cut-off level of ischemic myocardium,...
