Background and Purpose-Soluble corin was decreased in coronary heart disease. Given the connections between cardiac dysfunction and stroke, circulating corin might be a candidate marker of stroke risk. However, the association between circulating corin and stroke has not yet been studied in humans. Here, we aimed to examine the association in patients wtith stroke and community-based healthy controls. Methods-Four hundred eighty-one patients with ischemic stroke, 116 patients with hemorrhagic stroke, and 2498 healthy controls were studied. Serum soluble corin and some conventional risk factors of stroke were examined. Because circulating corin was reported to be varied between men and women, the association between serum soluble corin and stroke was evaluated in men and women, respectively. Results-Patients

Aims Underuse of oral anticoagulants (OACs) is commonly observed among patients with atrial fibrillation (AF), which hinders stroke prevention in AF. Shared decision-making (SDM) can help enhance adherence by minimizing patients’ misunderstanding of treatment and aligning care with their preferences. Decision aids (DAs) have been developed to facilitate the SDM process. This study aimed to: (i) evaluate the effects of DAs on AF patients’ knowledge, decisional conflict, OAC uptake, and adherence and on the incidence of stroke and bleeding; and (ii) explore characterizing factors associated with enhanced DA effectiveness. Methods and results Five databases were searched. Meta-analysis was conducted using RevMan 5.3 when data were available. Comparative analysis between effective and ineffective DAs was conducted to determine the DA designs associated with better effects. Ten studies were included. Pooling results indicated that DAs reduce decisional conflict related to warfarin use [mean difference = −0.10; 95% confidence interval (CI): −0.18 to −0.02; P = 0.01] and enhance OAC uptake [risk ratio: 1.03; 95% CI: 1.01–1.05; P = 0.004]. The effects of DAs on adherence and incidence of stroke and bleeding were unclear. Comparative analysis revealed that DAs with key elements of SDM (situation diagnosis, choice awareness, option clarification, benefits and disadvantages, and patient’s preference) and pre-consultation delivery are more likely to be effective in promoting SDM and OAC uptake. Conclusions DAs are promising in promoting SDM and OAC uptake in patients with AF. The evidence on adherence and incidence of stroke and bleeding remains uncertain. More trials with rigorous study design and longer follow-up are necessary to obtain evidence.

Acanthopanax senticosus (Rupr. et Maxim.) Harms (AS), a traditional herbal medicine, has been widely used to treat ischemic heart disease. However, the underlying cellular mechanisms of its benefits to cardiac function remain unclear. The present study examined the effects of total flavones from AS (TFAS) on L-type Ca(2+) channel currents (ICa-L ) using the whole cell patch-clamp technique and on intracellular calcium ([Ca(2+) ]i ) handling and cell contractility in rat ventricular myocytes with the aid of a video-based edge-detection system. Exposure to TFAS resulted in a concentration- and voltage-dependent blockade of ICa-L , with the half-maximal inhibitory concentration (IC50 ) of 283.12 µg/mL and the maximal inhibitory effect of 36.49 ± 1.95%. Moreover, TFAS not only increased the maximum current in the current-voltage relationship but also shifted the activation and inactivation curves of ICa-L toward the hyperpolarizing direction. Meanwhile, TFAS significantly reduced amplitudes of myocyte shortening and [Ca(2+) ]i with an increase in the time to 10% of the peak (Tp) and a decrease in the time to 10% of the baseline (Tr). Thus, the cardioprotective effects of TFAS may be attributed mainly to the attenuation of [Ca(2+) ]i through the direct inhibition of ICa-L in rat ventricular myocytes and consequent negative effect on myocardial contractility.
