Enhanced External Counterpulsation in the Treatment of Chronic Refractory Angina: A Long‐term Follow‐up Outcome from the International Enhanced External Counterpulsation Patient Registry

“…Compared with other patients, the 146 patients who did not complete their 3-year follow-up were younger (64.3 ± 11.7 versus 66.4 ± 10.7 years, p<0.05), their angina was more severe (CCSIII/IV 91.7% versus 88.8%, p<0.01) and frequent (10 [4-20] versus 6 [3][4][5][6][7][8][9][10][11][12][13][14] episodes/week, p<0.01), and history of HF was more prevalent (44.8% versus 33.8%, p<0.01). However, the workload they achieved on exercise stress test at baseline; their LVEF, the duration, distribution, and extent of their CAD; history of prior MI, previous revascularization, other cardiovascular risk factors, and medication use were similar to other patients.…”

Comparison of patients undergoing enhanced external counterpulsation and spinal cord stimulation for refractory angina pectoris

“…Patients with refractory angina, as might be expected, have according to Loh [26] a relatively high rate of events over a 12 months follow-up period. In this study two patients (1%) died of cardiac events and were lost to follow-up.…”

Impact of Enhanced External Counterpulsation on Canadian Cardiovascular Society Angina Class in Patients with Chronic Stable Angina: A Meta‐analysis

“…Fifty-seven full-text articles were evaluated, of which 44 were excluded for evaluating a different end point or not having adequate data, yielding a total of 13 studies reporting data on CCS class ( Figure 1). [11][12][13][14][15][16][17][18][19][20][21][22][23] Table 1 describes the characteristics of the included studies. A total of 949 patients were included in the overall analysis.…”
