LONDON - Short people have a 50 percent higher risk of having a heart problem or dying from one, when compared to tall people, a new study says, though weight, blood pressure and smoking habits remain more important factors.

Previous studies have suggested a link between height and heart problems like angina, heart attacks and angioplasties. This is the first major review of such studies, including research from around the world, confirming the relationship.

Experts did not consider patients' heights objectively, but within the context of a particular country's population. They found the shortest people in the population were one and a half times more likely to have heart problems or die from them than the tallest people.

"We don't want to scare short people, but perhaps they should be extra cautious about their lifestyle," said Borge Nordestgaard, a professor of genetic epidemiology at the University of Copenhagen. He was not connected to the study.

Height's impact on heart disease was still less important than things like smoking, which increases the chance of a heart ailment by up to four times, he said.

Scientists aren't sure why short people might be more susceptible to heart problems, but think there could be several explanations. Being short might be a result of being poor, meaning people of small stature could be undernourished and vulnerable to health problems in general.

Experts also suggested there could be a biological explanation, such as a hormone imbalance that hurts the heart. Scientists also suspect that because short people have smaller arteries, those could theoretically get clogged quicker with cholesterol and be more easily damaged by any changes in blood pressure.
