We have greatly enjoyed reading the recently published article by Suzuki and colleagues [1]. The authors retrospectively evaluated clinical characteristics and outcomes in 68 consecutive patients with infective endocarditis (IE). Of the 68 patients 25 patients (37%) were complicated with cardioembolic stroke. When made a comparison between 19 with early cardiac surgery and 6 with conventional treatment in those with cardio-embolic strokes the authors found that in-hospital mortality was quite low in patients with early cardiac surgery compared to patients treated with conventional therapy. The effect of early surgery for IE with cerebral complications on clinical and neurologic outcomes, has not been clarified and which patients should undergo early surgery remains a conundrum [2]. Murai et al. very recently reviewed the data of 170 consecutive patients with active left-sided IE with cerebral complications [3]. The authors divided patients into 2 groups according to National Institutes of Health Stroke Scale (NIHSS) score; 33 patients had severe stroke (NIHSS ≥ 11) and 137 had nonsevere stroke (NIHSS ≤ 10). The results of this study

revealed that in patients with nonsevere stroke, the survival rate in the early surgery group was significantly greater than that in the conventional treatment group; and patients complicated by severe stroke had a poor prognosis, regardless of the treatment strategy [3]. These findings suggest that early surgical intervention within 2 weeks may further improve clinical outcomes, with acceptable mortality and neurologic prognosis in patients with active IE complicated by nonsevere stroke. Therefore, we think that reanalysis of the data by Suzuki and colleagues according to the stroke severity may provide valuable information. Conflict of interest The authors report no relationships that could be construed as a conflict of interest. References [1] M. Suzuki, S. Takanashi, Y. Ohshima, Y. Nagatomo, A. Seki, I.
