LD-DSE indicates low-dose dobutamine stress echocardiography; Ref., reference number; Stress, stress echocardiography protocol; Total Pts, number of patients with chronic ischemic heart disease and impaired left ventricular systolic function studied with LD-DSE and subsequently followed up for the development of an adverse event (death or nonfatal myocardial infarction); Avg F/U, average period of follow-up after LD-DSE; Annualized Event Rate, percentage of patients per year who developed an adverse event during follow-up after LD-DSE; Viable, +Re, patients with viability (contractile reserve) demonstrated by LD-DSE who underwent revascularization and were then followed up; Viable, -Re, patients with viability (contractile reserve) demonstrated by LD-DSE who did not undergo revascularization and were then followed up; Not Viable, patients without contractile reserve by LD-DSE who were followed up for adverse events; and MI, nonfatal myocardial infarction.
Prognostic value of contractile reserve detected with LD-DSE in patients with chronic ischemic heart disease and impaired left ventricular systolic function. The annualized rate of death or MI is tabulated in patients with viable myocardium by LD-DSE depending on whether they did or did not undergo revascularization and also in those patients without viable myocardium.
