ABSTRACT The relationship between risk factors for coronary heart disease (CHD) and renal stone disease has been studied in a population of more than 2 000 middle-aged men. The only positive association found was a slight increase in diastolic BP among stone formers and a higher stone prevalence in untreated hypertensives. Furthermore, the prevalence of a history of renal stones in male survivors of myocardial infarction (MI) was similar to that found in the population study. An investigation of the vitamin D intake by means of a dietary questionnaire revealed no differences between stone formers, healthy controls and MI survivors. Contrary to other reports, the present study indicates that the risk factor profile for CHD in stone formers is similar to that in the general population.
