Researchers from the Heart Institute at Intermountain Medical Center in Murray, Utah, have devised a better way to determine an individual's risk for problems, such as heart attack and heart failure, according to a new study.
The research team has developed the Intermountain Risk Score, a measurement tool that looks at age and sex, but also adds the results of routine blood tests, which are not included in the assessment system commonly used by physicians today.
Researchers at Intermountain compared the Intermountain Risk Score with the Framingham Risk Score, currently the gold standard for measuring future coronary heart disease risk. The Framingham index looks at total cholesterol, HDL cholesterol, blood pressure, diabetes, age, and gender.
"Framingham does a good job of classifying groups of patients. But it's not as good at indentifying an individual's risk for disease," says Benjamin Horne, PhD, director of cardiovascular and genetic epidemiology at the Heart Institute at Intermountain Medical Center, and the principal author of the study.
That's where the Intermountain Risk Score can help.
"Our research has shown that the Intermountain Risk Score really improves a doctor's ability to measure patient risk. And it does it by including two simple and inexpensive tests: the complete blood count and metabolic profiles," he says.
Results of the study from the Heart Institute at Intermountain Medical Center will be presented at 1:30 pm, EST, on Sunday, March 14, at the American College of Cardiology's 59th annual scientific session in Atlanta.
Researchers followed over 5,000 patients who were treated for angiography, or vascular imaging. By combining the patients' Framingham Risk Score with their Intermountain Risk Score, researchers found that they were 30 percent more likely to correctly determine a woman's risk, and 57 percent more likely to determine a man's risk for a cardiovascular problem or death within 30 days of the angiography. The results remained substantially better than the Framingham score alone after one year (23 percent for women and 46 percent for men) and at five years (29 percent for women and 25 percent for men).
"Adding the Intermountain Risk Score to the Framingham Risk Score substantially improves our ability to determine an individual's risk of future coronary heart disease and associated problems," says Dr. Horne.
The Framingham Risk Score was developed as part of the Framingham Heart Study, which began in 1948 as a project of the National Heart, Lung and Blood Institute and Boston University. The objective of the study was to identify common characteristics that contribute to cardiovascular disease by following its development over a long period of time in a large group of participants who had not yet developed symptoms or suffered a heart attack or stroke.
Researchers at Intermountain Medical Center followed patients an average of three years after their angiogram, and some were followed for up to 10 years.
"We are in the process of replicating these findings at an academic center in North Carolina. Our previous studies of the Intermountain Risk Score showed that it applies very well both to patients and to the general population in different geographic settings, so we expect it will improve on the Framingham Risk Score in that East Coast population as well," Dr. Horne said. "We are also evaluating which health conditions are best predicted by the Intermountain Risk Score, and how changes over time in laboratory values influence the scoring system's ability to predict health outcomes."
Dr. Horne says that the goal at Intermountain Healthcare is to create an online risk score calculator to help clinicians around the world better assess their patients' health.

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...
