Green tea and coffee contain various bioactive compounds (e.g., polyphenols), and their consumption has been proposed to decrease the risk of cardiovascular diseases. Here, we investigated the associations between the consumption of green tea and that of coffee and the prevalence of coronary artery disease (CAD) in Japanese patients. The study group was 612 patients who underwent coronary angiography at Tokyo Medical Center between July 2008 and February 2017. CAD was confirmed in 388 of the patients: one-vessel disease (1-VD, n=166); two-vessel disease (2-VD, n=112); three-vessel disease (3-VD, n=110). Myocardial infarction (MI) was found in 138 patients. After adjustment for well-known atherosclerotic risk factors and other dietary habits, greater green tea consumption was significantly inversely associated with CAD prevalence (p for trend=0.044), and the patients who drank >3 cups/d had a lower prevalence of CAD compared to those who drank <1 cup/d (odds ratio [OR]: 0.54, 95% CI: 0.30-0.98). Greater green tea consumption (>3 cups/d) was also associated with a decreased prevalence of 3-VD (OR: 0.49, 95% CI: 0.24-0.98, p-trend=0.047) and MI (OR: 0.51, 95% CI: 0.27-0.97, p-trend=0.037). In contrast, coffee consumption was not associated with CAD or MI. In subgroup analyses, the inverse association between green tea consumption and CAD or MI was found in the high intake groups of vegetables or fruits but not in the low intake groups of vegetables or fruits. These results suggest a beneficial effect of green tea consumption, especially with a diet rich in vegetables and fruits, against coronary atherosclerosis in Japanese.

Aims: The long-term prognostic value of the bioavailability of L-arginine, an important source of nitric oxide for the maintenance of vascular endothelial function, has not been investigated fully. We therefore investigated the relationship between amino acid profile and long-term prognosis in patients with a history of standby coronary angiography. Methods: We measured the serum concentrations of L-arginine, L-citrulline, and L-ornithine by high-speed liquid chromatography. We examined the relationship between the L-arginine/L-ornithine ratio and the incidence of all-cause death, cardiovascular death, and major adverse cardiovascular events (MACEs) in 262 patients (202 men and 60 women, age 65±13 years) who underwent coronary angiography over a period of ≤ 10 years.Results: During the observation period of 5.5±3.2 years, 31 (12%) patients died, including 20 (8%) of cardiovascular death, while 32 (12%) had MACEs. Cox regression analysis revealed that L-arginine/L-ornithine ratio was associated with an increased risk for all-cause death (unadjusted hazard ratio, 95% confidence interval) (0.940, 0.888–0.995) and cardiovascular death (0.895, 0.821–0.965) (p<0.05 for all). In a mod el adjusted for age, sex, hypertension, hyperlipidemia, diabetes, current smoking, renal function, and log10-transformed brain natriuretic peptide level, cardiovascular death (0.911, 0.839–0.990, p=0.028) retained an association with a low L-arginine/ L-ornithine ratio. When the patients were grouped according to an L-arginine/L-ornithine ratio of 1.16, the lower L-arginine/L-ornithine ratio group had significantly higher incidence of all-cause death, cardiovascular death, and MACEs. Conclusion: A low L-arginine/L-ornithine ratio may be associated with increased 10-year cardiac mortality.

Background:Preprocedural dual antiplatelet therapy (DAPT) in percutaneous coronary interventions (PCI) has been shown to improve outcomes; however, the efficacy of the procedure and its complications in Japanese patients remain largely unexplored, so we examined the risks and benefits of DAPT before PCI and its association with in-hospital outcomes.Methods and Results:We analyzed data from patients who had undergone PCI at 12 centers within the metropolitan Tokyo area between September 2008 and September 2013.Our study group comprised 6,528 patients, of whom 2,079 (31.8%) were not administered preprocedural DAPT. Non-use of preprocedural DAPT was associated with death, postprocedural shock, or heart failure (odds ratio [OR]: 1.47, 95% confidence interval [CI]: 1.10–1.96, P=0.009), and postprocedural myocardial infarction (OR: 1.41, 95% CI: 1.18–1.69, P<0.001) after adjusting propensity scores for known predictors of in-hospital complications. Non-use of DAPT was not associated with procedure-related bleeding complications (OR: 0.98, 95% CI: 0.71–1.59, P=0.764).Conclusions:Approximately one-third of the patients who underwent PCI did not receive preprocedural DAPT despite guideline recommendations. Our results indicate that patients undergoing PCI with DAPT have a lower risk of postprocedural cardiac events without any increased bleeding risk. Further studies are needed to implement the use of DAPT in real-world PCI.
