Abstract PDF: Salt reduction is important for reducing hypertension and the risk of cardiovascular events and stroke. Despite knowledge about the ill consequences, many people continue to consume high levels of salt in their diet. This paper introduces salt-reducing programs for individual, population, and country-level strategies to reduce salt intake. To effectively decrease salt intake, it is necessary to reduce the consumption of high-salt foods and replace high-salt seasonings with low-salt alternatives. Thus, healthcare professionals must effectively provide information on salt-reduction for patients with hypertension. Social strategies, such as voluntary sodium reduction targets for the food industry, are necessary to promote population strategies for salt reduction. In this paper, we examine a brief report on new salt intake values based on chronic disease risk reduction and explain the utilization of mobile health technologies to reduce salt consumption. Considering the relationship between dietary salt intake and the risk of chronic disease, ways to remove the barriers to strategies for salt reduction should be considered, as it is the most effective way for the prevention and control of hypertension and cardiovascular disease in the future.

Background
The “comparison of triflusal and clopidogrel effects in secondary prevention of stroke based on cytochrome P450 2C19 (CYP2C19) genotyping (MAESTRO)” study was a prospective, multicenter, randomized, open-label, and blind genotype trial. We performed a subgroup analysis of the MAESTRO study to explore the relationship between VerifyNow P2Y12 assay with regard to CYP2C19 polymorphisms and smoking status in patients with non-cardiogenic ischemic stroke who underwent clopidogrel treatment.
Methods
For the study, patients treated with clopidogrel and who underwent VerifyNow P2Y12 assay was selected from the MAESTRO study.
Results
Of the 393 patients in 18 hospitals, 256 (65%) patients in 12 hospitals were entered for this subgroup analysis. P2Y12 reaction unit (PRU) was significantly lower and percent inhibition (% INH) was higher in the current smoking group than in the nonsmoking group (p<0.001). The same results were also observed in the good genotype group when compared with the poor genotype group (p<0.001). Among the groups, significant lower PRU and higher % INH was demonstrated in current smoking with good genotype group. However, there was no difference in PRU and % INH between current smoking with poor genotype group and nonsmoking with good genotype group, suggesting that clopidogrel activity was concurrently related to CYP2C19 polymorphisms and smoking status.
Conclusions
Regarding secondary stroke prevention, patients who were current smokers and had a poor genotype for clopidogrel metabolism may benefit from clopidogrel treatment similar to that in patients who were nonsmokers and had a good genotype.
