Abstract: | OBJECTIVE: To investigate the changes of plasma hydrogen sulfide (H(2)S) in patients with coronary heart disease (CHD). METHODS: Plasma H(2)S levels were measured in 40 patients with CHD and 17 angiographically normal patients by sulfide-sensitive electrodes, and the variation of plasma H(2)S levels was analyzed in different clinical types of CHD and in different types of coronary artery lesions. The association of plasma H(2)S levels with the risk factors of CHD was also analyzed. RESULTS: Plasma H(2)S levels were significantly lowered in CHD patients in comparison with that in angiographically normal control subjects (26.10+/-14.27 micromol/L vs 51.74+/-11.94 micromol/L, P<0.001). In CHD patients, plasma H(2)S levels in unstable angina patients (UAP, 23.60+/-14.41 micromol/L) and acute myocardial infarction patients (AMI, 19.98+/-7.516 micromol/L) were significantly lower than that in stable angina patients (SAP, 38.41+/-14.53 micromol/L, P<0.05). No significant difference in plasma H(2)S levels was found between CHD patients with double-vessel and multi-vessel lesions (16.91+/-7.98 vs 18.39+/-7.78 micromol/L, P>0.05), but the two groups of patients had significantly lower plasma H(2)S levels than patients with single-vessel involvement (33.04+/-15.01 micromol/L, P<0.05 and P<0.01, respectively). Plasma H(2)S level was significantly lower in CHD patients with coronary artery occlusion than in patients with simple stenosis (19.04+/-9.55 vs 28.24+/-14.85 micromol/L, P<0.05). Among the CHD patients, H(2)S levels were significantly lower in smokers than in non-smokers (27.54+/-10.37 vs 32.24+/-15.77 micromol/L, P<0.05), also lower in hypertensive patients than in normotensive patients (20.36+/-8.69 vs 33.77+/-15.86 micromol/L, P<0.01). Plasma H(2)S levels showed a significant inverse correlation with blood glucose (r=-0.493 6, P=0.001 6), but there were no significant correlations with sex, age, cholesterol, triglyeride, TC, low-density lipoprotein, high-density lipoprotein, or body mass index. CONCLUSION: Decreased plasma H(2)S levels may correlate with the severity of CHD and changes of the coronary artery, and may implicate the risk factors of CHD such as smoking, hypertension, and high blood glucose. |
