Chatbot Check-Ins could spot heart failure trouble before It's too late

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Established diagnosis of chronic HF with reduced, mildly reduced, or preserved ejection fraction, NYHA II-III * History of heart failure (HF) hospitalization within the last 6 months before enrollment, defined as the presence of dyspnea, elevated NT-proBNP ≥300 pg/mL (sinus rhythm) or ≥600 pg/mL (if AF), and 2 of the following: i. Rales on chest auscultation or signs of congestion on X-ray/CT scan; ii. Peripheral Oedema; iii. Loop diuretics IV at admission * Free of signs and symptoms of congestion, defined as JVP of \<8 cm, with no orthopnea, pulmonary rales, and with trace peripheral edema or no edema. * Stable doses of oral loop diuretics, if prescribed * Ability to provide informed consent Exclusion Criteria: * Acute coronary syndrome, cardiac surgery, pulmonary embolism, cerebrovascular accident, ablation of atrial flutter/fibrillation, valve repair/replacement, implanted cardioverter defibrillator or urgent PCI within the last 3 months * Planned interventions, including major cardiac surgery (coronary artery bypass grafting, valve repair/replacement, ventricular assist device, cardiac transplantation), coronary revascularization, implantation of a cardiac device or ablation of atrial flutter/fibrillation during the study * Previous cardiac transplantation and candidates for heart transplantation * Complex congenital heart disease * Heart failure due to active myocarditis, pericardial constriction, known hypertrophic cardiomyopathy or cardiac amyloidosis, or uncorrected severe valvular heart disease * Primary pulmonary hypertension, chronic pulmonary embolism, severe pulmonary disease * Cirrhosis, chronic active hepatitis, or other severe hepatic disease * Significant drug or alcohol abuse during the last year * Hemodialysis * Infective endocarditis * Any active cancer
