Angina silent ischemia and myocardial ischemia

• Silent Myocardial Ischemia

  Silent Myocardial Ischemia 787 Circulation Journal Vol.73, May 2009 minutes, silent myocardial ischemia can occur for minutes to over an hour (Figure 4).20 A diurnal pattern to the occur-rence of silent ischemia has been described in patients off therapy.21 This circadian pattern shows a rise in the inci-

• What is myocardial ischemia?

  ECG sufficient (and accurate)? As with angina pectoris, any given ECG change may not equal myocardial ischemia, but if the changes are transient and associated with chest discomfort, the diagnosis of myocardial ischemia is highly suspect. But, what if the patient has no symptoms associated with the ECG changes? Is this silent myocardial ischemia?

  MYOCARDIAL ISCHEMIA S. S. Moorthy, MD Patients with coronary artery disease (CAD) may develop symptom- atic (angina) or asymptomatic (silent) myocardial ischemia. Perioperative myocardial ischemia in CAD patients can occur secondarily due to hemodynamic aberrations or spontaneously, without hernodynamic changes.

  Silent Ischemia in People With Diabetes: A Condition That Must Be Heard Ramin Tabibiazar, MD, and Steven V. Edelman, MD A ngina pectoris has long been considered the cardinal symp-tom of myocardial ischemia. However, it is now known that angina pectoris may be a poor indicator for myocardial ischemia, particularly in patients with diabetes.

  Clinical techniques to detect “silent ischemia.” The defi- nition of “silent ischemia” varies from study to study. First, we must be consistent with what is meant by silent. Next, we must rigorously demonstrate ischemia. A wide variety of methods are now available to help demonstrate myocardial ischemia.
