"Severe deficiency is relatively rare, but in settings where this does occur it is very important to be proactive and avoid negative effects on the heart. Low levels of vitamin D are recorded by an estimated 23 per cent of people in Australia, 24 per cent of people in the US, and 37 per cent of people in Canada.Ĭhief investigator, UniSA's Prof Elina Hyppönen says appreciating the role of vitamin D deficiency for heart health could help reduce the global burden of cardiovascular disease. Low concentrations of vitamin D are common in many parts of the world, with data from the UK Biobank showing that 55 per cent of participants have low levels of vitamin D (<50 nmol/L) and 13 per cent have severe deficiency (<25 nmol/L). In Australia, CVD accounts for one in four deaths and costs the Australian economy five billion dollars each year, more than any other disease. Globally, cardiovascular diseases (CVDs) are the leading cause of death worldwide, taking an estimated 17.9 million lives per year. For participants with the lowest concentrations the risk of heart disease was more than double that seen for those with sufficient concentrations. The study, which is published in European Heart Journal today, shows that people with vitamin D deficiency are more likely to suffer from heart disease and higher blood pressure, than those with normal levels of vitamin D*. In the first study of its kind, researchers from the UniSA's Australian Centre for Precision Health at SAHMRI have identified genetic evidence for a role of vitamin D deficiency in causing cardiovascular disease. ![]()
