In one of the first studies to examine the relationship between consumption of different types of grains and premature coronary heart disease in the Middle East, researchers found that higher consumption of refined grains was associated with an increased risk of premature coronary heart disease among Iranian residents, while consumption of whole grains was associated with a reduced risk.
The results of the study will be presented at the American College of Cardiology (ACC) Middle East 2022 conference in conjunction with the 13th Congress of the Emirates Society of Cardiology, Medical Xpress reported.
This study evaluated the association between consumption of refined and whole grains and the risk of developing premature coronary heart disease.
Premature coronary heart disease is atherosclerotic narrowing of the coronary arteries in men under age 55 or in women under age 65. It is often asymptomatic in its early stages, but when it progresses, narrowing (stenosis) or plaque rupturing in the arterial wall can lead to chest pain (angina) and/or a heart attack. Risk factors include smoking, high cholesterol, high blood pressure and diabetes.
The study included 2,099 people with premature coronary heart disease from hospitals with cath labs in different cities and ethnic groups in Iran who underwent coronary angiography.
After adjustment for risk-limiting factors, higher consumption of refined grains was associated with an increased risk of premature coronary heart disease, whereas consumption of whole grains was inversely associated with a decreased risk of this disease.
