Oral health-related quality of life in patients with heart failure and left ventricular assist devices—results of a cross-sectional study

OBJECTIVES: The aim of this cross-sectional study was to compare oral health-related quality of life (OHRQoL) of patients with left ventricular assist device (LVAD) and heart failure (HF). MATERIAL AND METHODS: Seventy-four patients with LVAD were recruited from University Department for Cardiac Surgery, Leipzig Heart Center, Germany. A group of 72 patients with HF was composed by matching (age, gender, smoking). The German short form of oral health impact profile (OHIP G14) was applied. Health-related quality of life (HRQoL) was measured by short form 36 survey (SF-36). Dental conditions (decayed-, missing- and filled-teeth [DMF-T]), remaining teeth and periodontal findings were assessed. Statistics: t-test, Mann-Whitney U test, Kruskal-Wallis test, chi-square or Fisher test, linear regression. RESULTS: Age, gender, smoking, underlying disease, co-morbidities and oral findings were comparable between groups (p > 0.05). OHIP G14 sum score was 3.53 ± 6.82 (LVAD) and 2.92 ± 5.35 (HF; p = 0.70), respectively. The scales SF-36 physical functioning (p = 0.05) and SF-36 social functioning (p < 0.01) were worse in LVAD. In the LVAD group, the DMF-T and remaining teeth negatively correlated with OHIP G14 sum score (p < 0.01). In HF patients, positive correlations were found between OHIP G14 and D-T (p < 0.01) and remaining teeth (p = 0.04). Moreover, DMF-T (p = 0.03) and remaining molars/premolars (p = 0.02) were negatively correlated with SF-36 scales in HF. CONCLUSIONS: Oral health and OHRQoL was comparable between LVAD and HF; thereby, OHRQoL reflected the clinical oral status. CLINICAL RELEVANCE: Dental care, with beginning in early stage of HF, should be fostered to preserve teeth and support quality of life before and after LVAD implantation.
