[Magnesium, calcium, zinc, potassium, total and HDL cholesterol and total creatine kinase in 37 cases of instable angina: a correlation study].
Plasma and erythrocyte magnesium (P-Mg, E-Mg), zinc (P-Zn, E-Zn) and potassium (P-K, E-K), plasma calcium (P-Ca), HDL-cholesterol and total cholesterol and total creatine kinase (TCK) were determined in 37 cases (26 men, 11 women) of unstable angina pectoris (UAP) on the first day of hospitalization. The same variables, except P-K and TCK, were measured in 58 male and 53 female reference subjects. The methods of measurement were emission spectrometry for K, atomic absorption spectrometry for Mg, Ca and Zn, and the R CK NAC-activated Merckotest for TCK. According to the normality of distributions, statistical analysis of results was performed either by parametric or nonparametric tests. Multiple (R), simple (r) and Spearman (rs) correlation coefficients were calculated, and only significant correlations (p less than or equal to 0.05) were accepted. There was no significant R for UAP patients. For UAP men, r was negative and significant between P-Mg and E-K, but positive between P-Ca and P-Zn, as for reference subjects; and rs was negative and significant between P-Zn and TCK. For UAP women, only rs was positive and significant, between P-Mg and TCK. In the UAP population, contrary to the reference population, there were no significant differences relative to sex. In comparison with reference men, UAP men presented a significant (p less than 0.005) increase in E-Mg and significant (p less than 0.001) decreases in P-Ca and P-Zn.(ABSTRACT TRUNCATED AT 250 WORDS)
