Brief Summary

The correlation between endothelial dysfunction and the risk of coronary heart disease is well known through previous studies. The degradation of the function of nitric oxide acting on the endothelium of blood vessels is mainly explained by reduction of synthesis, loss due to oxidative stress, and decreased sensitivity to vascular dilatation action. In particular, patients with high blood pressure have been known to have impaired vascular endothelial function through animal experiments and several clinical studies, mainly due to increased biomechanical friction in the blood vessels and decreased biological availability of nitric oxide, which in turn causes incongruity in the production of nitric monoxide and changes in normal vascular dilatation. There have also been reports recently that early diagnosis and treatment may improve endothelial dysfunction and prevent the progression of coronary artery disease. However, the reality is that the drugs available in vasospastic angina patients with endothelial dysfunction are very limited. Until recently, beta-blockers were reported to inhibit vascular dilatation of adrenaline stimuli, a drug corresponding to relative contraindications in vasospastic angina patients, with one study reporting that propranolol cannot, but rather exacerbates, vasospastic angina. However, a series of reports on the vascular dilatation of the recently developed third-generation beta-blockers have reinvented the role of beta-blockers in vasospastic angina, especially nebivolol (selective, continuous beta-blockers) is known to act on β-1 adrenaline receptor blockings and endothelium to create vascular dilatation, and also to stimulate β-3 adrenaline receptors to cause nitric oxide generation and antioxidant effects in the endothelium of blood vessels. Therefore, this clinical trial seeks to find whether nebivolol will inhibit vascular contraction in hypertensive patients and will work in angiospastic angina patients.

Outcome Measures

Primary Outcomes (1)

  • Changes in coronary spasm

    The descriptive statistics (mean subject number, standard deviation, median value, minimum value, and maximum value) of changes in the baseline and 12-week outcomes will be presented for each treatment group, and the comparison between the three groups for ANOVA or ANOVA Kruskal-Wallis test. Changes in each group will be analyzed using Paired t-test or Wilcoxon signed rank test. An ANCOVA analysis will be performed when there are more influencing factors.

    Baseline to 12 weeks

Secondary Outcomes (3)

  • Changes in Quality of Life

    Baseline to 12 weeks

  • Changes in mean sitting systolic blood pressure and mean sitting diastolic blood pressure

    Baseline to 6, 12 weeks

  • Percentage of target blood pressure reached

    Baseline to 6, 12 weeks
