Tóm tắt
Of 209 patients with heart failure treated with combined cardiac resynchronization therapy and implantable cardioverter-defibrillator therapy, appropriate cardioverter-defibrillator shocks occurred at 34-month follow-up in 22 of 121 patients (18%) on statins and in 30 of 88 patients (34%) not on statins (P = .009). Deaths occurred in 3 of 121 patients (2%) on statins and in 9 of 88 patients (10%) not on statins (P = .017). Stepwise Cox regression analysis showed that significant independent prognostic factors for appropriate shocks were use of statins (risk ratio = 0.46), smoking (risk ratio = 3.5), and diabetes (risk ratio = 0.34). Significant independent prognostic factors for the time to mortality were use of statins (risk ratio = 0.05), use of digoxin (risk ratio = 4.2), systemic hypertension (risk ratio = 14.2), diabetes (risk ratio = 4.3), and left ventricular ejection fraction (risk ratio = 1.1).
