London ? Short people have a 50 percent higher risk of having a heart problem or dying from one than 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.

Researchers in Finland looked at 52 previous papers with data on height and heart problems in more than 3 million men and women.

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.

On average, short people were under 5 feet 3 inches and tall people were at least 5 feet 9 inches.

The study was paid for by the Finnish Foundation for Cardiovascular Research and others. It was published online Wednesday in the European Heart Journal.

“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.
