Painless Myocardial Ischemia

Currently, numerous clinical studies by domestic and foreign cardiologists have clearly shown that the presence of silent myocardial ischemia (SMI) significantly worsens the prognosis of patients with coro-nary heart disease (CHD). Patients with SMI represent a high-risk group in terms of the development of cardiovascular complications compared to patients who do not have episodes of ischemia. A.I. Martynov et al. (1995) note that the risk of sudden death in patients with SMI increases by 5-6 times, the development of myocardial infarction and chronic heart failure - by 1.5 times, more often there is a need for revascularization and / or repeated surgical intervention. A number of researchers consider "silent" ischemia a poor prognostic sign, since its presence is associated with an increased risk of unstable angina, myocardial infarction and sudden death. Since “silent” ischemia does not manifest itself as any discomfort in the heart region, its significance is often underestimated.
