Abstract
<p><strong>INTRODUCTION:</strong></p> <p>Telemonitoring (TM) is a method that leverages telecommunications to track patient health from a distance, playing a key role in the follow-up and preventive medicine of chronic heart failure (HF) patients. Currently there is a lack of robust evidence for which patients would benefit the most from such programs, and such better help clinicians decide who to refer.</p> <p><strong>OBJECTIVE:</strong></p> <p>To identify patient characteristics associated with improved cardiovascular outcomes in HF patients enrolled in a TM program, to help optimize patient selection and improve program effectiveness.</p> <p><strong>METHODS:</strong></p> <p>Data was obtained and analysed from 31 HF patients in a TM program, comparing several biochemical and clinical endpoints in the year prior and after joining the program.</p> <p><strong>RESULTS:</strong></p> <p>The sample included 24 males (77%) with a mean age of 67 years, with multiple cardiovascular risk factors (CVRF) (61% hypertensive; 74% dyslipidaemic; 36% diabetic; 16% obese; 16% smoker) and multiple co-morbidities (23% chronic kidney disease; 19% atrial fibrillation; 16% sleep apnoea; 7% chronic obstructive lung disease). The majority of patients had ischaemic heart disease (81%) and a mean left ventricular ejection fraction (LVEF) of 34%. The most frequent TM alert was body-weight increase (59%), and the majority of the alerts were resolved without the need for a hospital visit (67%).</p> <p>After one year of follow-up, patients showed a mean decrease in hospitalizations (-0.7 mean; 0.95 SD), admission days (-5.8 mean; 11.0 SD), emergency room visits (-0.3 mean; 1.4 SD), NYHA class (-0.4 mean; 0.7 SD), diuretic dose (-0.7 mean; 33.3 SD), BNP levels (-1542.3 mean; 5000 SD), LDL levels (-30.6 mean; 51.9 SD), and an increase in LVEF (6.4 mean; 8.4 SD). Significant differences were found in number of hospitalizations (p<0.01), days in hospital (p<0.01), NYHA class (p<0.01), LDL levels (p<0.01), and LVEF (p<0.01) (Table 1). Multivariate analysis was performed to identify which characterists best correlate with positive clinical and biochemical outcomes. A significant reduction in clinical outcomes was observed in patients with higher previous hospitalizations, prolonged admissions, emergency room visits, NYHA functional class, diuretic dose, and lower LVEF, indicating that clinically worse patients with multiple recent events seem to benefit the most from this program.</p> <p><strong>CONCLUSION:</strong></p> <p>HF patients with advanced disease showed the most benefit from telemonitoring, with reductions in hospitalizations and improvements in NYHA class and LVEF. The presence of additional risk factors or comorbidities alone did not predict better outcomes, suggesting instead telemonitoring is particularly beneficial for patients with multiple recent cardiac events.</p>
