Trial Outcomes & Findings for The Impact of Zinc Supplementation on Left Ventricular Function in Nonischemic Cardiomyopathy (NCT NCT00696410)
NCT ID: NCT00696410
Last Updated: 2017-11-06
Results Overview
The intervention group (patients with systolic heart failure) was given Zinc Acetate 50 mg po three times daily for 10 months. The change from baseline in markers of cardiac collagen turnover (PINP) in patients with systolic heart failure after 10 months of zinc acetate was measured and compared with a single measure from healthy controls.

Participant Flow
Patient were mainly recruited from the University of Michigan outpatient Cardiovascular clinic. 10 healthy controls (to quantify "normal" values and QA laboratory results for novel measures) were recruited from the community via advertisement.
The study was intended to run for 6 months. After further discussion with experts in zinc therapy, we opted to extend the study to 10 months.
Participant milestones
| Measure |
Zinc Acetate
The intervention group consisted of patients with heart failure. Patients were given Zinc Acetate 50 mg po three times a day for 10 months. The intended intervention group was n=40, of which n=38 were enrolled. Of these 38, n=25 completed 10 mo of follow-up.
|
Control
The control group consistent of 10 persons without any known health conditions who provided laboratory samples at a single encounter to quantify "normal" values for the novel labs measured. No intervention was provided to the healthy controls.

PRIMARY outcome
Timeframe: Baseline (time 0) and after 10 months of Zinc Acetate.Population: Power was determined using prior studies examining the change in PINP and (separately) PIIINP in heart failure following administration of aldactone. Results below are PINP. For Controls, a single measure was obtained without further followup.
The intervention group (patients with systolic heart failure) was given Zinc Acetate 50 mg po three times daily for 10 months. The change from baseline in markers of cardiac collagen turnover (PINP) in patients with systolic heart failure after 10 months of zinc acetate was measured and compared with a single measure from healthy controls.
