[7 elements in patients with heart diseases and their relationship with blood pressure and biochemical target].

The trace elements Zn, Cu, Fe, and ordinary elements K, Na, Ca, Mg in serum of 711 patients with heart disease (HD) were determined with GGX-II atomic absorption spectrophotometer and flame photometer. It was found that the contents of K, Ca/Mg in HD were significantly lower than those in the control, while the content of Na, Mg, Zn, Fe, and Zn/Cu, Na/K were significantly higher than those in the control. There was a significantly negative correlation between K, Ca/Mg and blood pressure (BP), between Zn/Cu and HDL-ch, and a significantly positive correlation between Na, Zn, Fe, Zn/Cu, Na/K and BP, between Fe and Hct, between Zn/Cu and Hct, TG, VLDL-ch.
