Treatment with low-dose prasugrel might be more beneficial even in chronic stable coronary artery disease (CAD) patients treated with clopidogrel. We compared platelet reactivity between standard maintenance-dose and low-dose prasugrel in stable CAD patients.This multicenter study enrolled 164 stable CAD patients receiving dual antiplatelet therapy with aspirin and clopidogrel. Patients were randomly assigned to continue treatment with 75-mg clopidogrel daily (n = 80) or switch to 3.75-mg prasugrel daily (n = 84). Platelet reactivity was evaluated by measuring P2YThe PRU level was comparable between the two groups at baseline but was significantly lower in the prasugrel group than in the clopidogrel group on days 5 (133.0 vs. 156.8 PRU, P = 0.005) and 30 (124.3 vs. 158.0 PRU, P 0.001). On day 30, the PRU level was lower in the prasugrel group among patients categorized as poor and intermediate metabolizers but not among extensive metabolizers.Low-dose prasugrel achieves more consistent antiplatelet effects than clopidogrel irrespective of the metabolic phenotype in Japanese patients with stable CAD. Low-dose prasugrel might be also beneficial in the chronic phase without increasing the bleeding risk among stable CAD patients in other countries.

Key Clinical Message Refractory coronary vasospasm subsequent to reperfusion, such as cardiopulmonary resuscitation or revascularization, for myocardial infarction may respond to fasudil in the superacute phase. Continuous low-dose fasudil administration should be an option for refractory coronary vasospastic angina (VSA).

We herein report the first case of a single-incision laparoscopic access (SILA) adrenalectomy in Japan. A 74-year-old woman who was a hepatitis B virus carrier was referred to our hospital because of an abnormal screening result during a routine health checkup. Abdominal computed tomography and an endocrinologic workup revealed a 2-cm left adrenal tumor with primary aldosteronism. We prioritized the safety of the SILA adrenalectomy by choosing a left lower abdominal approach. A SILS port was inserted through a 2.5-cm incision. An ultrasonic coagulator was the main tool used during the surgical procedure. The duration of the surgery was 105 min and the blood loss was 1 ml. This result was comparable to that of a conventional laparoscopic adrenalectomy. Based on our experience, an SILA adrenalectomy is thus considered to be feasible and safe, with better cosmetic results and a greater overall patient satisfaction than that of a conventional laparoscopic adrenalectomy. However, further studies will be necessary before the universal adoption of this new technique can be considered.
