Blood-cadmium in hypertensives and normotensives

70 hypertensive patients and 70 controls matched for age and sex were investigated for a possible relationship between blood-cadmium and hypertension. No significant differences between the two groups were detected, although the blood-cadmium level was significantly higher in smokers as compared to non-smokers. These data do not support the hypothesis that cadmium is involved in the development of hypertension in man.
