Nailfold videocapillaroscopy is a noninvasive technique used to examine the microvasculature. OBJECTIVE: In this study, we aimed to investigate the nailfold capillaroscopic abnormalities in heart failure patients with reduced and preserved ejection fraction and compare those with control group. METHODS: Three groups of patients were recruited for the study: HFrEF group includes the patients with heart failure with reduced ejection fraction (HFrEF), HFpEF group, patients with heart failure with preserved ejection fraction (HFpEF) and control group, healthy asymptomatic individuals. Nailfold videocapillaroscopy was performed with a videodermatoscope and all nailfold images were evaluated for enlargement and hemorrhages. RESULTS: Abnormal videocapillaroscopic findings including enlargement and\/or hemorrhages were present in 7 (24%) patients in HFrEF group, 19 (66%) patients in HFpEF group and 11 (37%) in control group. The number of patients with abnormal videocapillaroscopic findings were significantly greater in HFpEF group compared to HFrEF (p\u200a&lt;\u200a0.05) and control groups (p\u200a&lt;\u200a0.05). However, no significant difference was observed in videocapillaroscopic findings between HFrEF and control groups. CONCLUSIONS: Our study showed that microvascular abnormalities demonstrated by videodermatoscopic examination of nailfold capillaries are considerably more common in HFpEF patients compared to HFrEF and control groups.<\/jats:p>","DOI":"10.3233\/ch-200968","type":"journal-article","created":{"date-parts":[[2020,9,8]],"date-time":"2020-09-08T09:58:09Z","timestamp":1599559089000},"page":"115-121","source":"Crossref","is-referenced-by-count":19,"title":["Abnormal
