Check exclusion criteria of each trial listed, related hearth issues (?), normally protocol specify very well what are these "heart issues", or you find a generic phrase like:
"Any disorder, unwillingness or inability, not covered by any of the other exclusion criteria, which in the investigator's opinion, might jeopardise the subject's compliance with the extension of the trial"
Find below some exclusions examples (taken from links):
Patients with long QT syndrome or severe ventricular arrhythmias;
Patients using drugs that prolong the QT interval;
Patients with retinopathy or macular degeneration; (these can be diabetics but I haven't find a specific exclusion for diabetic patients).
Use of medications that are contraindicated with hydroxychloroquine: citalopram, escitalopram, hydroxyzine, domperidone, pipéraquine;
