The complete reversal effect following angiotensin-converting enzyme inhibitors or angiotensin receptor blockers and beta-blockers after the primary diagnosis of dilated cardiomyopathy

BACKGROUND: Whether combination administration of angiotensin-converting enzyme inhibitors (ACEIs), angiotensin receptor blockers (ARBs), and beta-blockers (BBs) has a “reversal” effect on cardiac structure and function for first-diagnosed idiopathic dilated cardiomyopathy (FSIDCM) patients with unc...

Sumario:BACKGROUND: Whether combination administration of angiotensin-converting enzyme inhibitors (ACEIs), angiotensin receptor blockers (ARBs), and beta-blockers (BBs) has a “reversal” effect on cardiac structure and function for first-diagnosed idiopathic dilated cardiomyopathy (FSIDCM) patients with unclear etiologies and inducements is unknown. MATERIALS AND METHODS: We studied the effect of the protocol on FSIDCM patients. The effect was investigated in 26 FSIDCM patients. The criteria of “complete reversal” included left ventricular end-diastolic diameter (LVEDD) ≤50 mm for females or ≤55 mm for males and left ventricular ejection fraction (LVEF) ≥45%; the criteria of “partial reversal” was the decreased rate of LVEDD (ΔLVEDD) >10% or the increase rate of LVEF (ΔLVEF) >10%; the criteria of “no reversal” included LVEDD >50 mm for females or >55 mm for males and ΔLVEDD <10%, and LVEF <45% and ΔLVEF <10%. RESULTS: Within the follow-up period, nine patients showed “complete reversal,” eight “partial reversal,” and nine “no reversal.” Improvements in echocardiogram parameters were the most significant in “complete reversal” patients (P < 0.001), followed by “partial reversal” and “no reversal” patients (P < 0.05). The QRS (Q wave, R wave, S wave) duration and symptoms duration in “complete reversal” patients were the shortest, followed by “partial reversal” and “no reversal” patients. CONCLUSION: ACEIs or ARBs and BBs have a “complete reversal” effect on the left ventricular size and function of some FSIDCM patients. Patients with a narrow QRS and short symptom duration may have a good response.
