Studies of plasma cardionatrin levels in coronary heart disease treated with microwave acupuncture

Plasma cardionatrin level （PCL） was determined with radioimmunoassay method in 20 healthy subjects and 28 patients with coronary heart disease （CHD） during pre-and post-treatment period with microwave acupuncture. The results showed that PCL in the patients with CHD during pretreatment was significanty lower than in the patients during post-treatment （P＜0.01） and in the healthy subjects （P＜0.01）. There was no significant difference between PCL in the patient with CHD during post-treatment and in the healthy subjects （P＞0.05）. There was signtificant difference of PCL during pre and post-treatment（P＜0.01）. In 10 patients with CHD complicated by hypertension, the PCL in 18 patients with normotension is not signtificanty differents between pre and post-treatment （P＞0.05）. Finally, the mechanism of change in PCL in the patients with CHD during pre and post-treatment was briefly discussed.
