Feeling Content May Reduce Cardiovascular Risk

Dear readers,

My grandfather used to advise me “Be happy with your lot in life,” stressing contentment as a goal. New research this week indicates that his advice is associated with better cardiovascular risk factors and outcomes. On the other hand, exposure to a range of “heavy metals” is associated with greater calcification of heart arteries. Beware of your air and water quality. Coffee and tea get thumbs up for heart disease risk.

In addition, vegans (like me) are challenged to get enough creatine in the diet and even a small amount can lower homocysteine. Eating fruit for the antioxidants boosts your manhood, good to know. Visceral fat measured by ultrasound is associated with early atherosclerosis, a sad state of affairs. We finish with two brain articles: the MIND diet and delayed cognitive impairment, along with small vessel changes on MRI and future dementia. Many of my patients get a non-contrast brain MRI (self-pay) to look for white matter chronic ischemic changes and the finding leads them to institute a stricter lifestyle program.

Be well,
Joel Kahn, MD, FACC

    • Metal exposure from environmental pollution is associated with increased calcium buildup in the coronary arteries at a level comparable to traditional risk factors, according to a new study. The findings support that metals in the body are associated with the progression of plaque buildup in the arteries and potentially provide a new strategy for managing and preventing atherosclerosis.

    • Studying the health data of more than 300,000 participants in the UK Biobank, researchers in China and Sweden have found that drinking caffeine is associated with a lower risk of developing multiple cardiometabolic disorders.

      These include conditions such as hypertension, stroke, diabetes, or coronary heart disease. According to some estimates, having two of these disorders at once, as opposed to just one, can more than double the risk of death.

      Participants in the study who consumed a moderate amount of caffeine each day – roughly three or more cups of coffee or five or more cups of tea – had more than a 40 percent lower relative risk of developing two or more cardiometabolic diseases over the proceeding years.

    •  In this cohort study of 232 participants, early-life growth parameters, and particularly abdominal VAT development, were associated with a higher cIMT and carotid stiffness in adolescence. These findings suggest that assessment of adipose tissue development during childhood can aid characterization of lifetime risk trajectories and tailoring of cardiovascular prevention and risk management strategies.
