"We wanted to understand why this occurs so that we can identify the small group of patients born premature who may need advice from their health care provider about this cardiovascular risk," said study author Paul Leeson, a professor of cardiology at the University of Oxford's Cardiovascular Clinical Research Facility in the U.K., in a press release. "The changes we have found in the right ventricle are quite distinct and intriguing." The study was funded by the British Heart Foundation. The human heart contains four chambers: the right and left atria -- which receive and collect blood -- and right and left ventricles, which pump blood from the heart into the circulatory system and rest of the body. The ventricle on the right side of the heart, specifically, pumps blood from the heart to the lungs, according to the National Heart Lung and Blood Institute. When breathing air in, a cycle kicks off in which oxygen is passed from the lungs through blood vessels and into the blood. Then, carbon dioxide (waste) is passed from the blood through the lungs where it's removed when you breathe out. The left atrium is what receives this oxygen-rich blood from the lungs, which is then pumped out by the left ventricle into the main artery of the body, the aorta. Then it is delivered to the rest of the body. The researchers followed a group of premature babies born in the 1980s until they were about 25. They were given standard heart tests checking for blood pressure and cholesterol, in addition to MRI machines to measure patients' blood vessels and heart structures. They then created a computer model to determine how much blood is being pumped in their hearts. "Their hearts appear to be slightly smaller, they had slightly thicker walls and had a slight reduction of the blood they are pumping," Leeson told CBS News' Alphonso Van Marsh of those born prematurely, when compared to those born at full term. People with these types of changes in the right ventricle's structure are more likely to have mild to moderate cases of high blood pressure (hypertension), and are at an increased risk for heart failure or cardiovascular-related death, according the researchers.
