Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.
