Progression of chronic heart failure depends on various additional pathophysiologic factors like blood pressure, arrhythmias, congestion. Early detection of any alteration using telemonitoring of multiple vital parameters may avoid severe decompensation requiring hospital admission. The feasibility and the clinical outcome using a new telemonitoring device for recording multiple vital parameters and allowing communication on individual state of health is investigated. Twenty-four patients with chronic heart failure (mean age 65 years, mean LV ejection fraction 35%) requiring at least one hospital admission during the past year were investigated. Twice a day, the vital-parameters were measured (weight, blood pressure, heart rate and rhythm, oxygen saturation, respiration rate) and patients information on well being, shortness of breath, medication, and request for contact were received. Intra-individual comparison was carried out between the 12 month before inclusion in this study and 12 month under telemonitoring surveillance (extrapolated, if necessary). Performing over 10 500 measurements during 5751 patient days, critical events were diagnosed for 55 events concerning relative weight gain (43 episodes), blood pressure (6), decrease in oxygen saturation (3), new onset of atrial fibrillation with tachyarrhymia (3). Of these, 45 events were controlled on an outpatient basis by changing medication or external cardioversion. Only 10 patients required re-admission. Thus, the number of admission to the hospital could be reduced by 62%, those of days spent in hospital by 69%. Non-invasive telemonitoring of multiple vital parameters combined with patients statements on their health condition and out-patient treatment on the basis of these findings is found to be an effective and reliable approach to avoid hospital readmission for patients with chronic heart failure.
