Researchers recommend considering both BMI and waist circumference in risk assessm...
A Kaiser Permanente study found that women who experienced gestational diabetes during pregnancy had a larger carotid artery wall thickness, indicating an increased risk of early atherosclerosis and heart disease. This finding suggests that reproductive complications can signal future disease risk.
Research suggests that a history of gestational diabetes may be a risk factor for early atherosclerosis in women during midlife. The study found that pregnant women who developed gestational diabetes had a slightly larger carotid artery intima-media thickness, an early measure of sub-clinical atherosclerosis, compared to those who didn't.
A study of 37 obese adolescents found that even after controlling for physical activity, low levels of sleep remained a significant predictor of cardiometabolic risk. Objective sleep assessment may be a useful screening tool to identify at-risk adolescents.

A nationwide study found larger daily temperature changes and higher average dew points were associated with increased stroke hospitalization rates. Lower annual temperatures also linked to higher hospitalization and death rates from ischemic strokes.
A new imaging technique can diagnose aortic disease and predict potential complications in patients with bicuspid aortic valve. Blood flow changes were found to be driven by specific types of abnormal aortic valves, and the study demonstrated a direct association between blood flow patterns and aortic diseases.
A study found that patients undergoing PCI have a higher risk of dying from non-cardiac diseases than heart disease, with only 37% of deaths being cardiac-related. The researchers attribute this to improved cardiac therapies, such as medication and catheterization laboratory technologies.
A new study using genetic signals has strengthened the case for high triglyceride levels as a cause of heart disease. The findings also suggest that high-density lipoprotein (HDL) cholesterol does not have a protective effect on cardiovascular health, contradicting conventional wisdom.
A large national study found that elevated blood pressure as young as age 18 is a warning sign of cardiovascular disease developing later in life. The study identified distinct blood pressure patterns from ages 18 to 55 that reveal people at high risk for calcification of coronary arteries, a marker for heart disease.
A recent study published in the European Journal of Preventive Cardiology found a causal link between depression symptoms and an increased risk of coronary heart disease. In contrast, no such association was found with stroke risk. The Whitehall II study, which followed over 10,000 civil servants in the UK for 20 years, suggests that r...
African American youth experiencing frequent discrimination during adolescence are at risk for chronic diseases like heart disease and diabetes. Emotional support from parents and peers can protect against stress-related damage.
A large prospective study has confirmed that vodka consumption is a major cause of early death in Russian men, with those who drink heavily facing a 60-70% increased risk. The study found that heavy vodka drinkers were more likely to die from alcohol-related causes such as poisoning, accidents, and violence.
A new study published in Psychosomatic Medicine found that children with depression are more likely to develop obesity, smoking habits, and lower physical activity levels. These factors can increase the risk of heart disease later in life, even as early as teenage years.
A University of Arizona researcher has shown that genetic mutations in the titin gene can cause skeletal muscle myopathy, a disease characterized by muscle weakness. The study, published in the Journal of General Physiology, could be an important step in developing treatments for this condition.
The Arab world has made significant strides in reducing premature death and disability, but still struggles with substantial burdens of communicable and non-communicable diseases. Governance and health systems are also critical to addressing these challenges.
Researchers at Dartmouth College have developed a new fluorescent compound to detect and measure cardiolipin, a unique lipid in cell membranes. The new dye, TTAPE-Me, improves upon existing methods for detecting cardiolipin, which is linked to various diseases including heart conditions, neurodegenerative disorders, and cancers.
New research published in The FASEB Journal found that tobacco smoke disrupts the circadian clock function in both lungs and brains, leading to reduced productivity, mood disorders, and depression. Quitting smoking may improve sleep quality and cognitive function by targeting a specific pathway involving the anti-aging molecule SIRT1.

The CANHEART health index found that 9.4% of Canadian adults and 16.6% of youth were in ideal cardiovascular health, while 37.3% of adults and 49.7% of youth had poor heart health. The study suggests that addressing behaviours can reduce cardiac risk factors.
Researchers found that increasing dietary fiber intake by just 1 extra portion of wholegrains and more fruit and vegetables can significantly lower the risk of heart disease. A 7g daily increase in fiber consumption was associated with a lower risk of CVD and CHD events.
A new study has found that heart disease is associated with an increased risk of cognitive decline and dementia in older postmenopausal women. Researchers analyzed data from nearly 6,500 U.S. women ages 65-79 and found that those with heart disease or vascular disease were 29% more likely to experience cognitive decline over time.
A study of 417 middle-aged women found that modest weight loss over two years reduced risk factors for heart disease and diabetes. Women who sustained a 10% or more weight loss benefited the most from this reduction in risk factors.
