The addition of pentoxifylline to conventional therapy improves outcome in patients with peripartum cardiomyopathy.

We have reported previously that despite treatment with angiotensin-converting enzyme inhibitors and beta blockers, the outcome of patients with peripartum cardiomyopathy (PPC) remains unfavorable. Similar to other etiologies of left ventricular dysfunction, we found elevated levels of tumor necrosis factor-alpha (TNF-alpha) in this group of patients. In the present study we sought to evaluate the effects of pentoxifylline, a drug known to inhibit the production of TNF-alpha, on clinical status, left ventricular function, and circulating plasma levels of TNF-alpha, in patients with PPC.
