Higher consumption of vitamin D was associated with an increased probability of myocardial infarction, with a daily intake of suggested as a critical level.

Does high consumption of vitamin D increase the risk of myocardial infarction?
Long-term high consumption of vitamin D may be associated with an increased risk of myocardial infarction.

May warrant caution with high vitamin D intake; leaves open causality and requires prospective confirmation.
A detailed investigation was carried out into the consumption of vitamin D from different sources in patients who had suffered from myocardial infarction, angina pectoris, and degenerative joint diseases. Randomly selected controls of the same ages and sex were drawn from the Central Bureau of Statistics. The consumption was significantly higher in infarction patients. A daily intake of 30 mug may be the critical level. Student's t test for trend showed increasing probability of myocardial infarction with increasing intake of vitamin D, and more infarction patients than controls had a history of kidney stone. Long-term high consumption of vitamin D may be a precipitating cause of myocardial infarction.

van der Linden (1974) conducted a case-control in Myocardial infarction, angina pectoris, and degenerative joint diseases. Vitamin D consumption vs. Age- and sex-matched controls was evaluated on Myocardial infarction. Higher consumption of vitamin D was associated with an increased probability of myocardial infarction, with a daily intake of suggested as a critical level.
