Safety and Efficacy of Doxycycline in Patients With Non-Ischemic Cardiomyopathy (DOXY-HF)
Non-ischemic cardiomyopathy and heart failure are highly influenced by the presence of systemic inflammation.
Doxycycline is a FDA-approved drug to treat bacterial infections which also shows powerful anti-inflammatory effects.
In this study we plan to determine the effects of Doxycycline in patients with stable heart failure and non-ischemic cardiomyopathy on peak of aerobic exercise capacity (peak V02) and ventilator efficiency measured with a cardiopulmonary test.
Systolic Heart Failure (NYHA II-III)

Placebo Comparator: Placebo
In this study of Safety and Efficacy of Doxycycline in Patients with Non-Ischemic Cardiomyopathy Population, we will enroll 24 patients with a clinical diagnosis of heart failure and non-ischemic cardiomyopathy (recent imaging study documenting LV ejection fraction <50%, and no history of coronary or ischemic heart disease) in a single-center, randomized, double-blinded, placebo-controlled clinical trial with allocation 1:1:1 to Doxycycline 100 mg twice daily or Doxycycline 20 mg twice daily or Placebo for 2 weeks.
