Abstract:

The aim of our study is to provide an assessment of heart rate variability (HRV) as a predictor for the survival of patients with pancreatic cancer (PCa). We conducted a retrospective, descriptive study. 53 consecutive patients who were newly diagnosed with pancreatic cancer (PCa), were included. In the end, 41 patients were included in the analysis, out of which 14 patients survived at least until the 24-month follow-up, while 27 patients died within 24 months from the diagnosis. These patients were monitored with 24-hour Holter electrocardiogram (ECG) prior to the initiation of any therapy for determining heart rate variability. To establish the cut-off values of HRV, 24-hour Holter ECG recordings of 20 healthy subjects were analyzed. In addition to heart rate analysis, HRV indices were also analyzed: SDNN, rMSSD, ULF and VLF. Median survival in patients with low value of SDNN was 9 months, compared to patients with hight SDNN where median survival was 15 months (Hazard ratio 2.301, 95% CI of ratio 0.9080 to 5.833, p= 0.034). Although low values of the HRV indices in the frequency domain were associated with reduced survival, no statistically significant differences were recorded. The reduction of heart rate variability indices is a negative prognostic factor in patients newly diagnosed with pancreatic cancer.
